1 00:00:05,720 --> 00:00:08,160 Speaker 1: Hey, welcome to Stuff to Blow your Mind. My name 2 00:00:08,200 --> 00:00:11,639 Speaker 1: is Robert Lamb and I'm Joe McCormick, and it's Saturday. 3 00:00:11,640 --> 00:00:14,280 Speaker 1: Time for a vault episode. This one originally aired on 4 00:00:14,360 --> 00:00:19,200 Speaker 1: June and it's called The Origins of Numerous e. This 5 00:00:19,280 --> 00:00:22,560 Speaker 1: is all about the human number since all right, let's 6 00:00:22,600 --> 00:00:28,040 Speaker 1: jump right in Welcome to Stuff to Blow Your Mind 7 00:00:28,320 --> 00:00:37,440 Speaker 1: production of my Heart Radio. Hey, welcome to Stuff to 8 00:00:37,440 --> 00:00:40,080 Speaker 1: Blow your Mind. My name is Robert Lamb and I'm 9 00:00:40,159 --> 00:00:42,239 Speaker 1: Joe McCormick. And today we're going to be looking at 10 00:00:42,320 --> 00:00:45,800 Speaker 1: an interesting question about the human mind and some of 11 00:00:45,840 --> 00:00:51,320 Speaker 1: it's possibly innate or possibly learned capacities, and those capacities 12 00:00:51,360 --> 00:00:54,480 Speaker 1: have to do with numbers. Were Today we're gonna be 13 00:00:54,560 --> 00:00:58,000 Speaker 1: looking at the question of the uh, the origins in 14 00:00:58,040 --> 00:01:02,000 Speaker 1: the brain of numerous See. Yeah, this is this is 15 00:01:02,000 --> 00:01:05,640 Speaker 1: one of those topics that I found rather interesting for 16 00:01:05,640 --> 00:01:07,399 Speaker 1: for a while, and it's it's a great one to 17 00:01:07,440 --> 00:01:10,560 Speaker 1: dive into because on one hand, there's the there's this 18 00:01:10,680 --> 00:01:12,559 Speaker 1: the stuff about it that just seems to be true 19 00:01:12,640 --> 00:01:15,160 Speaker 1: that you and you that we take for granted, and 20 00:01:15,200 --> 00:01:17,200 Speaker 1: then when you dive into it you find all sorts of, 21 00:01:18,000 --> 00:01:20,320 Speaker 1: you know, arguments on two different sides of the equation, 22 00:01:20,400 --> 00:01:23,560 Speaker 1: And sometimes a lot of the argumentation is about, like 23 00:01:23,600 --> 00:01:26,400 Speaker 1: where you're drawing the line between in this case, like 24 00:01:26,480 --> 00:01:31,520 Speaker 1: what is what is like preloaded hardware and software and 25 00:01:31,560 --> 00:01:37,240 Speaker 1: what is is learned? What is transmitted educationally, culturally, etcetera. 26 00:01:37,480 --> 00:01:40,440 Speaker 1: Like where what is what is our innate uh number 27 00:01:40,480 --> 00:01:44,119 Speaker 1: since and how does that then allow us to build 28 00:01:44,160 --> 00:01:48,240 Speaker 1: upon it numerous e mathematics, etcetera. Uh, you know when 29 00:01:48,240 --> 00:01:50,800 Speaker 1: did the numbers come in? You know, is there is 30 00:01:50,840 --> 00:01:54,560 Speaker 1: there something that is five, that is that is already 31 00:01:54,600 --> 00:01:58,640 Speaker 1: in the brain or is easily um more easily acquired 32 00:01:58,760 --> 00:02:01,160 Speaker 1: by the human brain for as compared to you know, 33 00:02:01,200 --> 00:02:05,040 Speaker 1: animal brains. Uh. You know you can ultimately can kind 34 00:02:05,080 --> 00:02:07,360 Speaker 1: of chase your tail through all of this and it's 35 00:02:07,360 --> 00:02:10,520 Speaker 1: it's it's a wonderful Uh. It's a wonderful experience, wonderful 36 00:02:10,560 --> 00:02:13,160 Speaker 1: topic we're gonna get into here now. Like so many 37 00:02:13,200 --> 00:02:15,480 Speaker 1: of the most interesting topics, one thing about it is 38 00:02:15,520 --> 00:02:18,640 Speaker 1: that you quickly realize, like the central now and that 39 00:02:18,720 --> 00:02:22,440 Speaker 1: you're discussing is much harder to define than you might guess. 40 00:02:22,520 --> 00:02:25,560 Speaker 1: If you know, like everybody knows what a number is, right, 41 00:02:25,680 --> 00:02:28,360 Speaker 1: you just know that intuitively, but could you give the 42 00:02:28,400 --> 00:02:34,040 Speaker 1: definition of a number? Please? I'll wait. Yeah, I would 43 00:02:34,040 --> 00:02:35,560 Speaker 1: love for everyone out there to think about that for 44 00:02:35,639 --> 00:02:38,680 Speaker 1: just a second. So what comes to your mind for me? Like, 45 00:02:38,800 --> 00:02:40,480 Speaker 1: if you just ask me that question, you don't give 46 00:02:40,520 --> 00:02:42,200 Speaker 1: me a chance to sort of like back it up. 47 00:02:42,480 --> 00:02:45,680 Speaker 1: The first thing I think about our our shorts cartoon 48 00:02:45,760 --> 00:02:49,160 Speaker 1: shorts on Sesame Street, you know, because ultimately, like that's 49 00:02:49,200 --> 00:02:52,560 Speaker 1: the case, we're sort of hit very early on with 50 00:02:52,560 --> 00:02:57,200 Speaker 1: with numerical and counting essentially propaganda, you know, like like 51 00:02:57,560 --> 00:03:00,320 Speaker 1: let us show you the way of the numbers. But yeah, 52 00:03:00,320 --> 00:03:02,200 Speaker 1: as we'll get into here, like what what is what 53 00:03:02,360 --> 00:03:07,119 Speaker 1: is actually already there? What is built upon, etcetera. Um, So, yeah, 54 00:03:07,160 --> 00:03:09,000 Speaker 1: I thought it would be good to get into a 55 00:03:09,160 --> 00:03:13,480 Speaker 1: you know, basically a brief discussion of just what numbers are. Now, 56 00:03:13,520 --> 00:03:15,600 Speaker 1: this might seem a bit elementary to many of you, 57 00:03:15,720 --> 00:03:18,840 Speaker 1: but first of all, I'd invite you to sit in 58 00:03:18,880 --> 00:03:21,640 Speaker 1: on an elementary math class or or just take a 59 00:03:21,639 --> 00:03:25,080 Speaker 1: look through an elementary student's math textbook and see how 60 00:03:25,160 --> 00:03:27,960 Speaker 1: that comparison stacks up with what you think. You know, 61 00:03:28,480 --> 00:03:32,080 Speaker 1: I find it it's often a uh learning experience about 62 00:03:32,080 --> 00:03:36,000 Speaker 1: oneself in one's own mathematical skills by by looking at 63 00:03:36,040 --> 00:03:39,200 Speaker 1: how kids today are learning math. Well, one of the 64 00:03:39,200 --> 00:03:41,800 Speaker 1: interesting things is that I don't think you can begin 65 00:03:41,960 --> 00:03:46,920 Speaker 1: to teach mathematics or even uh arithmetic sense by starting 66 00:03:46,920 --> 00:03:49,480 Speaker 1: with the most basic questions like what is a number? 67 00:03:49,560 --> 00:03:51,880 Speaker 1: You actually have to start at a higher level and 68 00:03:51,880 --> 00:03:55,160 Speaker 1: work your way down to that. Yeah. I think ultimately 69 00:03:55,240 --> 00:03:57,560 Speaker 1: numbers and math are are things that we we so 70 00:03:57,640 --> 00:03:59,920 Speaker 1: easily take for granted and we forget at a basically 71 00:04:00,000 --> 00:04:02,320 Speaker 1: ab what they actually are. Uh. So I think it's 72 00:04:02,360 --> 00:04:06,400 Speaker 1: helpful to sort of take a back step before moving 73 00:04:06,440 --> 00:04:09,680 Speaker 1: forward from in order to have that maximum wonder with 74 00:04:09,760 --> 00:04:14,200 Speaker 1: the topic. So UM. I remember looking at a couple 75 00:04:14,240 --> 00:04:17,640 Speaker 1: of sources on this, uh several years back when I 76 00:04:17,640 --> 00:04:20,000 Speaker 1: wrote an article on math for how Stuff Works. So 77 00:04:20,080 --> 00:04:23,919 Speaker 1: one of those was uh stanis laws the hainis what 78 00:04:24,000 --> 00:04:27,680 Speaker 1: are numbers really a cerebrial basis for number since and 79 00:04:27,720 --> 00:04:30,039 Speaker 1: that was published on Edge. But I also had a 80 00:04:30,040 --> 00:04:33,520 Speaker 1: wonderful book that sadly is um. I think it's at 81 00:04:33,520 --> 00:04:35,080 Speaker 1: the office, so I haven't I don't have access to 82 00:04:35,160 --> 00:04:38,040 Speaker 1: it right now, but it was by by two authors, 83 00:04:38,320 --> 00:04:41,800 Speaker 1: Richard Kurant and Herbert Robbins titled What is Mathematics? That 84 00:04:41,839 --> 00:04:47,080 Speaker 1: was from University Oxford University Press, published back in But um, 85 00:04:47,320 --> 00:04:48,800 Speaker 1: that's a great book if you just want to, like, 86 00:04:48,839 --> 00:04:51,479 Speaker 1: all right, I'm gonna start from the basics, let me 87 00:04:51,560 --> 00:04:53,760 Speaker 1: learn what math is, uh and and and you know 88 00:04:53,800 --> 00:04:57,040 Speaker 1: it bit and builds up from there. So as as 89 00:04:57,080 --> 00:04:59,360 Speaker 1: for what a number is, again, you probably don't need 90 00:04:59,400 --> 00:05:02,320 Speaker 1: more than that a moment of contemplation to to state 91 00:05:02,360 --> 00:05:04,719 Speaker 1: that it's a word, and it's a symbol, and it 92 00:05:04,800 --> 00:05:09,440 Speaker 1: represents account, not a vampire account, because that's where mind 93 00:05:09,680 --> 00:05:12,400 Speaker 1: my mind goes instantly as well again the sesame Street. 94 00:05:12,680 --> 00:05:17,000 Speaker 1: But but account as in UM an understanding of how 95 00:05:17,279 --> 00:05:19,600 Speaker 1: many things, an analysis of how many things there are 96 00:05:19,920 --> 00:05:23,280 Speaker 1: a quantity. I came across a definition of numbers that 97 00:05:23,640 --> 00:05:26,200 Speaker 1: I thought was very useful, and this was one that 98 00:05:26,320 --> 00:05:30,440 Speaker 1: was derived from a study that was authored by Raphael 99 00:05:30,520 --> 00:05:33,280 Speaker 1: Nunez at All, who is a figure I'll come back 100 00:05:33,320 --> 00:05:36,320 Speaker 1: to later in this episode. But this definition was that 101 00:05:36,560 --> 00:05:42,680 Speaker 1: numbers are discrete entities with exact values that are represented 102 00:05:42,720 --> 00:05:45,920 Speaker 1: by symbols in the form of words and signs. So 103 00:05:46,000 --> 00:05:48,599 Speaker 1: like each part of that definition I think contributes something 104 00:05:48,720 --> 00:05:52,040 Speaker 1: important about what a number is so first of all, discreet, 105 00:05:52,200 --> 00:05:56,440 Speaker 1: meaning each one is different from the others. Uh. Exact 106 00:05:56,680 --> 00:05:59,440 Speaker 1: values is very important to the concept of a number, 107 00:05:59,480 --> 00:06:04,560 Speaker 1: because because a number is different than a quantity, quantities 108 00:06:04,640 --> 00:06:06,880 Speaker 1: can be fuzzy, right Like you can look at a 109 00:06:06,960 --> 00:06:09,520 Speaker 1: quantity of something and say, I don't know, this seems 110 00:06:09,520 --> 00:06:13,400 Speaker 1: approximately more than this other thing. But seven is not 111 00:06:13,600 --> 00:06:17,719 Speaker 1: just more than five, It is exactly two more than five, 112 00:06:17,800 --> 00:06:21,640 Speaker 1: and that never changes. So yeah, so the numbers are exact. 113 00:06:21,720 --> 00:06:24,480 Speaker 1: And then finally, and you alluded to this in in 114 00:06:24,520 --> 00:06:28,440 Speaker 1: your definition you just cited it's represented by symbols such 115 00:06:28,440 --> 00:06:31,600 Speaker 1: as words or signs, And this also seems like a 116 00:06:31,680 --> 00:06:36,120 Speaker 1: very important thing, and that a number can exist independently 117 00:06:36,240 --> 00:06:39,920 Speaker 1: of a concrete object being counted. So in a world 118 00:06:39,960 --> 00:06:43,640 Speaker 1: without human mathematics, obviously there could still be a pile 119 00:06:43,760 --> 00:06:46,360 Speaker 1: of five rocks if there were no humans and no math. 120 00:06:46,560 --> 00:06:50,840 Speaker 1: But could there still be the number five without any rocks. 121 00:06:51,520 --> 00:06:56,040 Speaker 1: That's an open question. I think with numbers, you can store, manipulate, 122 00:06:56,080 --> 00:07:02,480 Speaker 1: and interpret the symbols themselves independent to any observable material reality. 123 00:07:02,560 --> 00:07:05,440 Speaker 1: To be counting, you can just say, what's five plus two? 124 00:07:05,520 --> 00:07:09,280 Speaker 1: Not like five apples plus two apples. Yeah, Like, I 125 00:07:09,320 --> 00:07:11,920 Speaker 1: guess it's irresistible to compare it to words in this respect, 126 00:07:11,920 --> 00:07:13,840 Speaker 1: even though it's not a one to one here. But 127 00:07:14,120 --> 00:07:16,400 Speaker 1: we we think about how you have like a word, 128 00:07:16,680 --> 00:07:19,240 Speaker 1: the word cat, that stands in for that thing you're 129 00:07:19,280 --> 00:07:21,880 Speaker 1: looking at, that that furry creature that is distinct from 130 00:07:21,920 --> 00:07:25,280 Speaker 1: other furry creatures. And once you have that label for it, 131 00:07:25,360 --> 00:07:29,120 Speaker 1: that enables communication and various other more advanced uses of 132 00:07:29,320 --> 00:07:33,320 Speaker 1: set information, uh, as opposed to just having to describe 133 00:07:33,520 --> 00:07:36,239 Speaker 1: the beast every time you need to tell someone about 134 00:07:36,280 --> 00:07:39,360 Speaker 1: it and not having like an easy peg for what 135 00:07:39,400 --> 00:07:41,240 Speaker 1: a cat is. If you you want to you know, 136 00:07:41,520 --> 00:07:44,320 Speaker 1: engage in metaphors, etcetera. You don't have to say the 137 00:07:44,320 --> 00:07:48,360 Speaker 1: four legged boss of my house every time? Right? Um? 138 00:07:48,480 --> 00:07:50,640 Speaker 1: And and so I mean this is where we get 139 00:07:50,640 --> 00:07:53,360 Speaker 1: into like the idea of Okay, what if I what 140 00:07:53,440 --> 00:07:55,920 Speaker 1: if I didn't have the word for cat, what could 141 00:07:55,960 --> 00:07:58,640 Speaker 1: I still do? Uh? You know? And likewise, if I 142 00:07:58,640 --> 00:08:00,800 Speaker 1: did not have the numbers, what could I still do? 143 00:08:00,880 --> 00:08:03,800 Speaker 1: And this is ultimately going to be a question that 144 00:08:04,200 --> 00:08:06,480 Speaker 1: we're going to go back and forth on throughout this episode. 145 00:08:06,480 --> 00:08:08,560 Speaker 1: And and uh, you know, their their arguments on both 146 00:08:08,600 --> 00:08:13,520 Speaker 1: sides essentially. But um, it comes down to this idea 147 00:08:13,680 --> 00:08:17,840 Speaker 1: of of of of of numeracy and also numbers, since 148 00:08:18,320 --> 00:08:21,760 Speaker 1: so I've read that the numeracy seems to entail first 149 00:08:21,760 --> 00:08:25,800 Speaker 1: of all, approximate representation of numerical magnitude and then two 150 00:08:25,920 --> 00:08:31,760 Speaker 1: precise representation of the quantity of individual items. And there's 151 00:08:31,840 --> 00:08:33,800 Speaker 1: there's an argument to be made that this is an 152 00:08:33,840 --> 00:08:36,880 Speaker 1: innate ability of human beings. Will discuss more what this 153 00:08:36,960 --> 00:08:39,600 Speaker 1: means in a bit, and will also discuss animals. Um. 154 00:08:39,679 --> 00:08:42,520 Speaker 1: And the idea here is that it that whatever is 155 00:08:42,559 --> 00:08:47,040 Speaker 1: innate there does not depend on individual or cultural acquisition 156 00:08:47,080 --> 00:08:51,320 Speaker 1: of mathematical knowledge. That mathematical knowledge is then built upon 157 00:08:51,760 --> 00:08:54,079 Speaker 1: what is already innate. Yeah, and I guess one of 158 00:08:54,120 --> 00:08:57,600 Speaker 1: the big questions we're looking at here is when humans 159 00:08:57,640 --> 00:09:00,600 Speaker 1: manipulate numbers with their brains, when they count, when they 160 00:09:00,640 --> 00:09:04,320 Speaker 1: do arithmetic, editions, attraction and all that, what part of 161 00:09:04,360 --> 00:09:07,160 Speaker 1: what they're doing is innate? What part is just they're 162 00:09:07,160 --> 00:09:11,319 Speaker 1: already in the brain without any education whatsoever. And what part, 163 00:09:11,400 --> 00:09:13,960 Speaker 1: if any, is a product of culture is something that 164 00:09:14,040 --> 00:09:16,480 Speaker 1: was invented at some point in history and has to 165 00:09:16,520 --> 00:09:21,520 Speaker 1: be learned. Yeah, Now it's interesting to to realize that 166 00:09:21,520 --> 00:09:25,439 Speaker 1: that numerous e appears to predate literacy in human culture 167 00:09:25,480 --> 00:09:30,240 Speaker 1: by several thousand years. Neolithic societies used clay and stone 168 00:09:30,280 --> 00:09:33,480 Speaker 1: counters to keep track of quantities of stored goods, for example, 169 00:09:34,120 --> 00:09:36,720 Speaker 1: and UH and counting was a primary function of written 170 00:09:36,760 --> 00:09:40,040 Speaker 1: records in the earliest state societies of the late fourth 171 00:09:40,080 --> 00:09:44,320 Speaker 1: millennium b C. This is pointed out by anthropologist Brian 172 00:09:44,320 --> 00:09:48,600 Speaker 1: and Fagan and Eleanor robson UH in the you Know 173 00:09:48,679 --> 00:09:51,080 Speaker 1: the Great Inventions of the Ancient World. But Robinson is 174 00:09:51,120 --> 00:09:55,560 Speaker 1: the author of Mesopotamian Math and the Literature of Ancient Summer, 175 00:09:55,960 --> 00:09:59,240 Speaker 1: so um I found their thoughts on this rather interesting 176 00:09:59,280 --> 00:10:02,440 Speaker 1: that they point that the first large scale evidence of 177 00:10:02,520 --> 00:10:05,959 Speaker 1: mathematics as an intellectual activity probably dates to the Middle 178 00:10:06,000 --> 00:10:10,320 Speaker 1: Bronze Agent Egypt around fifteen sixty b C. But that 179 00:10:10,320 --> 00:10:13,920 Speaker 1: would be mathematics as an intellectual activity more in the 180 00:10:13,960 --> 00:10:16,120 Speaker 1: realm of what you might see people doing with you know, 181 00:10:16,200 --> 00:10:19,800 Speaker 1: pure math today. Obviously, the more functional things like counting 182 00:10:19,880 --> 00:10:22,559 Speaker 1: go even further back, much further back. Yeah, this is 183 00:10:22,760 --> 00:10:24,840 Speaker 1: getting down to like, how do we keep track of 184 00:10:24,880 --> 00:10:27,000 Speaker 1: these goods? How do we trade with these goods? We 185 00:10:27,040 --> 00:10:30,280 Speaker 1: need things to stand in for certain quantities. And this 186 00:10:30,360 --> 00:10:32,520 Speaker 1: definitely came up in the past when we've talked about 187 00:10:32,840 --> 00:10:36,000 Speaker 1: some of the earliest written records that exist. A lot 188 00:10:36,040 --> 00:10:38,280 Speaker 1: of that. You might think, well, what are the earliest 189 00:10:38,320 --> 00:10:41,120 Speaker 1: written records? Is it you know, is it mythology? Is 190 00:10:41,120 --> 00:10:43,360 Speaker 1: it telling like a great poem about the creation of 191 00:10:43,360 --> 00:10:45,920 Speaker 1: the world. I mean, we do have very ancient examples 192 00:10:45,920 --> 00:10:48,679 Speaker 1: of that, but actually older than that are written records 193 00:10:48,720 --> 00:10:53,600 Speaker 1: that seem to usually denote uh quantities of property. Who 194 00:10:53,679 --> 00:10:56,880 Speaker 1: has how much of this? Or how much of this 195 00:10:56,960 --> 00:11:00,840 Speaker 1: do you owe me? And so forth? Yeah, and I think, uh, this, 196 00:11:01,160 --> 00:11:03,040 Speaker 1: like a number of topics we've discussed in the show, 197 00:11:03,040 --> 00:11:04,800 Speaker 1: I think a lot of it comes back to, you know, 198 00:11:04,880 --> 00:11:07,520 Speaker 1: some some key aspects of human cognition that there are 199 00:11:07,679 --> 00:11:10,400 Speaker 1: limits to what we've evolved to deal with, you know, 200 00:11:10,480 --> 00:11:13,840 Speaker 1: and then we have to to build upon upon that 201 00:11:14,000 --> 00:11:17,200 Speaker 1: natural ability. So, for example, it's one thing to know 202 00:11:17,280 --> 00:11:19,480 Speaker 1: how many bags of coffee you need to buy on 203 00:11:19,600 --> 00:11:22,679 Speaker 1: each grocery store visit in order for you or your 204 00:11:22,679 --> 00:11:25,400 Speaker 1: immediate family to get through to the next week. You know, Like, 205 00:11:25,440 --> 00:11:27,400 Speaker 1: if you're like me, you may not even need to 206 00:11:27,400 --> 00:11:29,520 Speaker 1: get into numbers at all. You know, you just realize, 207 00:11:29,520 --> 00:11:32,679 Speaker 1: well I have less than one bag, I'll need more 208 00:11:32,840 --> 00:11:34,720 Speaker 1: than that to get through the week. So I guess, 209 00:11:34,720 --> 00:11:37,240 Speaker 1: get one bag, and then once I have that patterned down, 210 00:11:37,280 --> 00:11:39,320 Speaker 1: I can just keep doing that for the rest of 211 00:11:39,360 --> 00:11:42,840 Speaker 1: my life. Wait, what what if your need for coffee explodes? 212 00:11:42,920 --> 00:11:48,040 Speaker 1: What if it just increases exponentially. Well that's a great question, 213 00:11:48,040 --> 00:11:49,480 Speaker 1: because you could, I guess, hand you could. You can 214 00:11:49,520 --> 00:11:53,240 Speaker 1: handle that at least for a while. Um uh, that's 215 00:11:53,480 --> 00:11:56,520 Speaker 1: the thing when complications enter the picture, be it um, 216 00:11:56,720 --> 00:12:01,240 Speaker 1: you know, fluctuations, or or just increase chan change. Or 217 00:12:01,679 --> 00:12:03,960 Speaker 1: how about this? What if you were buying coffee for 218 00:12:04,040 --> 00:12:06,920 Speaker 1: two different houses, so your house and I don't know, 219 00:12:06,960 --> 00:12:09,480 Speaker 1: maybe you have a vacation home, or maybe you agreed 220 00:12:09,520 --> 00:12:12,360 Speaker 1: to buy all the coffee for your parents house and 221 00:12:12,440 --> 00:12:15,360 Speaker 1: your siblings house. Oh and then how about this. You 222 00:12:15,400 --> 00:12:17,800 Speaker 1: also have a business and it sells coffee and you 223 00:12:17,840 --> 00:12:20,600 Speaker 1: need to provide it with coffee. Oh, now you have 224 00:12:20,640 --> 00:12:24,800 Speaker 1: two locations with two different streams of clientele. So I 225 00:12:24,840 --> 00:12:27,319 Speaker 1: mean the details of this, I guess is important. It's 226 00:12:27,320 --> 00:12:29,960 Speaker 1: just the idea that, like whatever is in your immediate 227 00:12:30,000 --> 00:12:34,760 Speaker 1: sphere regarding some level of number, since uh, and even 228 00:12:34,880 --> 00:12:36,960 Speaker 1: numerous e like you're gonna have to You're gonna have 229 00:12:37,000 --> 00:12:39,080 Speaker 1: to build upon that if you're going to deal with 230 00:12:39,120 --> 00:12:43,480 Speaker 1: some sort of larger experience that emerges out of human invention. 231 00:12:43,800 --> 00:12:45,800 Speaker 1: This just goes to highlight something that I think will 232 00:12:45,840 --> 00:12:49,240 Speaker 1: be increasingly apparent, as as we talked throughout the episode, 233 00:12:49,240 --> 00:12:53,280 Speaker 1: that what kind of sense of numbers you need has 234 00:12:53,440 --> 00:12:55,560 Speaker 1: very much to do with how you're making a living, 235 00:12:55,600 --> 00:12:57,800 Speaker 1: with what you have to do to get by. And 236 00:12:57,840 --> 00:13:00,640 Speaker 1: so some people may have ways of making a living 237 00:13:00,760 --> 00:13:05,120 Speaker 1: that are essentially almost totally devoid of need for for 238 00:13:05,240 --> 00:13:08,000 Speaker 1: numbers of more than a handful, whereas other people have 239 00:13:08,080 --> 00:13:11,400 Speaker 1: ways of making a living that are heavily exact number dependent. 240 00:13:12,520 --> 00:13:15,640 Speaker 1: And I like how you mentioned a handful of numbers, 241 00:13:16,080 --> 00:13:19,000 Speaker 1: um So, so I think we're gonna do another episode 242 00:13:19,000 --> 00:13:22,360 Speaker 1: in the future that is going to deal more specifically 243 00:13:22,360 --> 00:13:24,600 Speaker 1: with like the creation of numbers, the invention of numbers, 244 00:13:24,600 --> 00:13:27,840 Speaker 1: and different number of systems. But it is interesting to 245 00:13:27,880 --> 00:13:30,960 Speaker 1: think of our fingers and ultimately our toes as well, 246 00:13:31,360 --> 00:13:34,920 Speaker 1: because one of the initial steps here is that humans 247 00:13:34,920 --> 00:13:37,319 Speaker 1: had to come up with ways to augment their number. 248 00:13:37,400 --> 00:13:40,560 Speaker 1: Since we already mentioned using little tokens, to stand in 249 00:13:40,800 --> 00:13:42,680 Speaker 1: you know, clay tablets and what not to stand in 250 00:13:42,760 --> 00:13:45,600 Speaker 1: for things. But another method, of course is just that's 251 00:13:45,640 --> 00:13:49,240 Speaker 1: immediately available is turning to fingers and or toes. You 252 00:13:49,240 --> 00:13:51,959 Speaker 1: have tin fingers, you have tin toes. And for this reason, 253 00:13:52,040 --> 00:13:55,439 Speaker 1: various numerical systems depend on groups of five, ten, or twenty. 254 00:13:56,080 --> 00:13:58,400 Speaker 1: Based ten or decimal systems stem from the use of 255 00:13:58,440 --> 00:14:03,079 Speaker 1: both hands, while based twenty or vegicimal systems are based 256 00:14:03,080 --> 00:14:05,880 Speaker 1: on the use of fingers and toes. So the argument 257 00:14:05,880 --> 00:14:07,960 Speaker 1: here is that you know this is ultimately an externalization 258 00:14:07,960 --> 00:14:10,280 Speaker 1: of number, since that this is the root, the roots 259 00:14:10,320 --> 00:14:14,600 Speaker 1: of mathematics, or the bedrock upon which mathematics may be built. Um. 260 00:14:14,640 --> 00:14:16,680 Speaker 1: And I guess that's the way I keep coming back 261 00:14:16,679 --> 00:14:18,200 Speaker 1: to thinking about it, or the way that i've I've 262 00:14:18,200 --> 00:14:21,120 Speaker 1: thought about it for a while, the idea of of 263 00:14:21,120 --> 00:14:24,480 Speaker 1: of of number since and numeracy and mathematics, it's like 264 00:14:24,520 --> 00:14:28,520 Speaker 1: building this tower. You know that we we keep building. Uh, 265 00:14:28,520 --> 00:14:32,280 Speaker 1: that you have these different types of numbers that are utilized. Uh, 266 00:14:32,320 --> 00:14:36,600 Speaker 1: you have different um types of mathematics. And the higher 267 00:14:37,440 --> 00:14:41,200 Speaker 1: the tower a sense, the greater height, the greater power, 268 00:14:41,440 --> 00:14:44,960 Speaker 1: the greater your vantage point from which to understand the cosmos, 269 00:14:45,600 --> 00:14:48,120 Speaker 1: a cosmos that that some for instance Max tech Mark 270 00:14:48,360 --> 00:14:51,000 Speaker 1: goes as far as to describe as a single, vast 271 00:14:51,120 --> 00:14:54,880 Speaker 1: mathematical object. So I actually got the idea to talk 272 00:14:54,880 --> 00:14:56,440 Speaker 1: about this today when I was reading a couple of 273 00:14:56,480 --> 00:15:00,320 Speaker 1: recent articles that I found very interesting. One was a 274 00:15:00,480 --> 00:15:04,560 Speaker 1: news feature in Nature from June one by Colin Barris 275 00:15:04,720 --> 00:15:08,640 Speaker 1: called how did Neanderthals and other ancient humans learn to count? Uh? 276 00:15:08,680 --> 00:15:10,760 Speaker 1: And so, so that got my brain going on this. 277 00:15:10,840 --> 00:15:13,840 Speaker 1: But also I was reading an article by Philip Ball 278 00:15:13,880 --> 00:15:18,400 Speaker 1: and Eon magazine called how natural is numerous? E uh 279 00:15:18,440 --> 00:15:22,120 Speaker 1: Now as to the specific archaeological evidence, linguistic evidence, and 280 00:15:22,160 --> 00:15:25,880 Speaker 1: other stuff about how how humans in fact first started 281 00:15:25,920 --> 00:15:28,960 Speaker 1: displaying number. Since we might come back to that more 282 00:15:29,120 --> 00:15:32,520 Speaker 1: in a future episode, I wanted to focus more today 283 00:15:32,560 --> 00:15:36,280 Speaker 1: on this question of how natural is numerousy to what 284 00:15:36,480 --> 00:15:40,920 Speaker 1: degree is our number? Since in eight and so? Of course, 285 00:15:41,040 --> 00:15:43,240 Speaker 1: you know, like we were saying at the beginning, it 286 00:15:43,400 --> 00:15:46,320 Speaker 1: can feel very natural to be able to count to 287 00:15:46,440 --> 00:15:50,560 Speaker 1: a hundred and thirty seven, But basic numerical literacy that 288 00:15:50,680 --> 00:15:54,200 Speaker 1: includes counting up to arbitrary numbers and the ability to 289 00:15:54,320 --> 00:15:57,760 Speaker 1: do basic math, it might seem so natural that you 290 00:15:57,880 --> 00:16:01,480 Speaker 1: just assume it is an evolved by biological capacity, right, 291 00:16:01,600 --> 00:16:05,160 Speaker 1: something that any human brain could just automatically do naturally. 292 00:16:05,840 --> 00:16:09,440 Speaker 1: But actually there's some question about this. The question would be, 293 00:16:09,440 --> 00:16:12,920 Speaker 1: how do we know that numerous e is not to 294 00:16:13,120 --> 00:16:17,880 Speaker 1: some degree and invented cultural capacity more like the ability 295 00:16:17,920 --> 00:16:21,280 Speaker 1: to read sheet music or the ability to play football, 296 00:16:21,400 --> 00:16:23,760 Speaker 1: something that generally people can do if they're taught how 297 00:16:23,800 --> 00:16:26,400 Speaker 1: to do it, but it's not something that's like in 298 00:16:26,440 --> 00:16:30,960 Speaker 1: our biology, is a part of our ancestral evolved capabilities. 299 00:16:31,440 --> 00:16:33,520 Speaker 1: One of the things I love about this discussion or 300 00:16:33,720 --> 00:16:36,480 Speaker 1: or even argument, if you want to frame it that way, 301 00:16:37,120 --> 00:16:38,560 Speaker 1: and it's you know, it's been going on for a while, 302 00:16:38,600 --> 00:16:41,880 Speaker 1: is it Also it lines up rather well with the 303 00:16:41,880 --> 00:16:46,320 Speaker 1: the the argument slash discussion of whether mathematics is a 304 00:16:46,400 --> 00:16:50,280 Speaker 1: human invention or a human discovery, you know, And and 305 00:16:50,640 --> 00:16:52,720 Speaker 1: it's one of those two where I don't know, being 306 00:16:52,880 --> 00:16:57,240 Speaker 1: one that's not like professionally engaged with either side, I've 307 00:16:57,280 --> 00:16:59,000 Speaker 1: tended to I tend to sort of fall in the 308 00:16:59,000 --> 00:17:01,840 Speaker 1: middle and think, what seems like it's it's it's both, right, 309 00:17:01,880 --> 00:17:04,560 Speaker 1: I mean, it's it's both. This thing that we uh 310 00:17:04,640 --> 00:17:07,359 Speaker 1: that is the universe and is a description of the universe. 311 00:17:07,760 --> 00:17:10,399 Speaker 1: It is both this thing that we have some level 312 00:17:10,440 --> 00:17:14,840 Speaker 1: of innate capability for, and yet it is also there's 313 00:17:14,880 --> 00:17:17,879 Speaker 1: also undeniably, um you know, plenty of it that is 314 00:17:17,920 --> 00:17:20,679 Speaker 1: acquired that is, uh, that is written down in a 315 00:17:20,720 --> 00:17:24,040 Speaker 1: textbook and then or or put into a sesame street 316 00:17:24,080 --> 00:17:26,760 Speaker 1: short and then related in you know, into the mind. 317 00:17:27,240 --> 00:17:31,439 Speaker 1: So uh, that's again, that's that's that's something that I 318 00:17:31,480 --> 00:17:34,320 Speaker 1: just find um fascinating about the topic. Well, yeah, I 319 00:17:34,320 --> 00:17:36,960 Speaker 1: mean I think you could argue that it is to 320 00:17:37,119 --> 00:17:40,240 Speaker 1: some degree, like you could say, it's like the rules 321 00:17:40,280 --> 00:17:43,480 Speaker 1: of chess. So like chess is not something that exists 322 00:17:43,520 --> 00:17:46,760 Speaker 1: outside of human invention. Humans had to invent it. But 323 00:17:46,880 --> 00:17:50,359 Speaker 1: once you have invented the rules, it's not up to 324 00:17:50,720 --> 00:17:54,160 Speaker 1: human chess players to say, like what is the most 325 00:17:54,240 --> 00:17:57,720 Speaker 1: advantageous move or something like that. That's just objectively true, 326 00:17:57,880 --> 00:18:00,840 Speaker 1: right you know, So, like you have aided a system 327 00:18:00,880 --> 00:18:04,000 Speaker 1: of rules and symbols, but it turns out within that 328 00:18:04,040 --> 00:18:07,639 Speaker 1: system of rules and symbols, you can discover objectively true 329 00:18:07,680 --> 00:18:12,160 Speaker 1: facts about the universe. Right, So I guess it would 330 00:18:12,160 --> 00:18:16,120 Speaker 1: be like if chess gave you objective understanding of actual warfare. 331 00:18:16,160 --> 00:18:19,159 Speaker 1: I don't know. Maybe it does to a certain extent um, 332 00:18:19,200 --> 00:18:22,640 Speaker 1: except that horses. Horses are not limited by going what 333 00:18:23,080 --> 00:18:25,160 Speaker 1: two spaces us and then one to the side, or 334 00:18:25,359 --> 00:18:27,399 Speaker 1: or one space up and then one diagonal, depending on 335 00:18:27,440 --> 00:18:30,000 Speaker 1: how you which is it? Which is it considered? Is 336 00:18:30,040 --> 00:18:32,720 Speaker 1: the horse going two up and then one over or 337 00:18:32,760 --> 00:18:35,560 Speaker 1: is it going one up and then one diagonal the night? Rather, 338 00:18:35,640 --> 00:18:37,679 Speaker 1: it's not the horse. I think it's two up and 339 00:18:37,720 --> 00:18:40,199 Speaker 1: one over. It's two up and one over. Yeah, it 340 00:18:40,320 --> 00:18:43,160 Speaker 1: is a fact of physics that bishops can only move diagonally. 341 00:18:44,400 --> 00:18:46,919 Speaker 1: Have you ever seen a bishop strathe? I have not, 342 00:18:48,040 --> 00:18:50,600 Speaker 1: It's true. But anyway, to come back to the main 343 00:18:50,720 --> 00:18:54,440 Speaker 1: question we're talking about here again, it's not so much 344 00:18:54,520 --> 00:18:57,400 Speaker 1: the bigger question about like is math a a pre 345 00:18:57,520 --> 00:18:59,960 Speaker 1: existing sort of fact of the universe or is it 346 00:19:00,119 --> 00:19:03,400 Speaker 1: human invention that merely describes the universe? The question here 347 00:19:03,400 --> 00:19:07,240 Speaker 1: would be uh, it is numerous e a baseline evolved 348 00:19:07,320 --> 00:19:10,480 Speaker 1: capability in the human brain, meaning like, do you have 349 00:19:10,720 --> 00:19:14,240 Speaker 1: number meat in your head? Or is it a cultural 350 00:19:14,280 --> 00:19:17,360 Speaker 1: invention that makes use of some meat in your head? 351 00:19:17,400 --> 00:19:20,720 Speaker 1: It makes use of the brain's natural capacities, but is 352 00:19:20,760 --> 00:19:25,240 Speaker 1: not itself and evolved innate capacity, not something that would 353 00:19:25,240 --> 00:19:34,160 Speaker 1: be arrived at unless you were taught it. Than now, 354 00:19:34,160 --> 00:19:37,440 Speaker 1: there is plenty of evidence that researchers point to as 355 00:19:38,080 --> 00:19:42,720 Speaker 1: as supporting the idea of a biologically endowed number sense. 356 00:19:43,359 --> 00:19:45,760 Speaker 1: And one thing that often gets pointed to here is 357 00:19:45,920 --> 00:19:49,960 Speaker 1: the is the capacity of other animals for certain kinds 358 00:19:50,000 --> 00:19:53,199 Speaker 1: of number consciousness. And so the question would be to 359 00:19:53,240 --> 00:19:56,600 Speaker 1: what extent are non human animals capable of numerous e 360 00:19:57,040 --> 00:19:59,840 Speaker 1: what kinds of number consciousness, if any, can they do 361 00:20:00,040 --> 00:20:02,760 Speaker 1: and straight? And where do they differ from us? So 362 00:20:02,920 --> 00:20:07,920 Speaker 1: studies with animals, including monkeys, some apes, marine mammals like dolphins, 363 00:20:07,960 --> 00:20:11,560 Speaker 1: and dogs have shown that these creatures do have some 364 00:20:11,720 --> 00:20:15,720 Speaker 1: basic innate sense of quantity. For example, they can look 365 00:20:15,760 --> 00:20:18,520 Speaker 1: at two groups of food items and they can usually 366 00:20:18,560 --> 00:20:21,520 Speaker 1: tell which one has more items in it, provided that 367 00:20:21,560 --> 00:20:24,840 Speaker 1: the numbers of items are small enough. So if it's like, 368 00:20:24,960 --> 00:20:28,399 Speaker 1: you know, fewer than ten items, more often than not 369 00:20:28,720 --> 00:20:31,880 Speaker 1: a dog can look at that and tell which which 370 00:20:31,920 --> 00:20:34,040 Speaker 1: pile has more food items in it and go to 371 00:20:34,119 --> 00:20:38,159 Speaker 1: that pile. And in fact it's sometimes even to surprising 372 00:20:38,160 --> 00:20:41,119 Speaker 1: extents there There was one study that Ball linked to 373 00:20:41,200 --> 00:20:45,080 Speaker 1: that I thought was interesting called quantity based Judgments in 374 00:20:45,119 --> 00:20:48,919 Speaker 1: the Domestic Dog, published in the journal Animal Cognition in 375 00:20:48,960 --> 00:20:53,000 Speaker 1: two thousand seven by camill Ward and Barbara be Smuts, 376 00:20:53,119 --> 00:20:56,320 Speaker 1: and these authors tested dogs on the mental management of 377 00:20:56,359 --> 00:20:58,840 Speaker 1: different food quantities, and one of the things they found 378 00:20:59,000 --> 00:21:01,880 Speaker 1: was that in in a second experiment they did so well. 379 00:21:01,920 --> 00:21:06,720 Speaker 1: Their first experiment was that they would simultaneously visually present 380 00:21:06,960 --> 00:21:10,639 Speaker 1: two options to a dog and they would see, you know, 381 00:21:10,720 --> 00:21:14,040 Speaker 1: does the dog reliably choose the larger quantity of food 382 00:21:14,080 --> 00:21:17,480 Speaker 1: instead of the smaller quantity? And they found that yes, 383 00:21:17,600 --> 00:21:19,600 Speaker 1: dogs on average do tend to go more for the 384 00:21:19,680 --> 00:21:22,320 Speaker 1: larger quantity when they can see both. But they found 385 00:21:22,359 --> 00:21:26,679 Speaker 1: that numerically close comparisons were more difficult, so like, you know, 386 00:21:26,720 --> 00:21:29,359 Speaker 1: if if it's like five versus six, the dog's going 387 00:21:29,400 --> 00:21:31,679 Speaker 1: to have a harder time going to the six than 388 00:21:31,760 --> 00:21:35,679 Speaker 1: if it's you know, eight versus three. But they also 389 00:21:35,760 --> 00:21:38,919 Speaker 1: found interestingly that in a second experiment they had some 390 00:21:38,960 --> 00:21:44,439 Speaker 1: additional conditions where the food was not visually available to 391 00:21:44,520 --> 00:21:46,560 Speaker 1: the dog at the time they made their choice, So 392 00:21:46,600 --> 00:21:49,360 Speaker 1: the food would be shown to the dog and then 393 00:21:49,440 --> 00:21:51,720 Speaker 1: hidden from the dog, and then the dog would have 394 00:21:51,760 --> 00:21:53,760 Speaker 1: to make a choice. So the question is does the 395 00:21:53,800 --> 00:21:57,560 Speaker 1: dog remember the differences in quantities when it can't see 396 00:21:57,600 --> 00:22:00,359 Speaker 1: it right in the moment. And they found yeah, even 397 00:22:00,440 --> 00:22:03,840 Speaker 1: in this case quote subjects still chose the larger quantity 398 00:22:03,880 --> 00:22:06,919 Speaker 1: more often than the smaller quantity when the food was 399 00:22:07,000 --> 00:22:10,639 Speaker 1: not simultaneously visible at the time of choice. And they 400 00:22:10,640 --> 00:22:13,919 Speaker 1: also said that they work to exclude other cues like 401 00:22:13,960 --> 00:22:16,840 Speaker 1: olfactory cues. You know, maybe the dog can smell more 402 00:22:17,040 --> 00:22:19,760 Speaker 1: food in one case than the other and uh and 403 00:22:20,000 --> 00:22:23,640 Speaker 1: queuing by the experiment ers. They work to eliminate those influences. 404 00:22:24,160 --> 00:22:27,199 Speaker 1: Uh So, it seems if there's really no chance that 405 00:22:27,359 --> 00:22:31,040 Speaker 1: dogs have culturally learned or invented number systems that they're 406 00:22:31,080 --> 00:22:34,720 Speaker 1: working from. Uh So, if they can more often than 407 00:22:34,760 --> 00:22:38,880 Speaker 1: not visually assess numbers of food items tell which grouping 408 00:22:38,920 --> 00:22:42,360 Speaker 1: has more even when they can no longer see them, 409 00:22:42,400 --> 00:22:44,600 Speaker 1: maybe you could interpret that as a sign that there's 410 00:22:44,600 --> 00:22:47,320 Speaker 1: some kind of innate capacity, not just in human brains, 411 00:22:47,320 --> 00:22:51,880 Speaker 1: but in the broader mammalian brain structure for understanding numbers, 412 00:22:51,920 --> 00:22:55,119 Speaker 1: at least in a rudimentary way. Right, Well, maybe not 413 00:22:55,200 --> 00:22:57,800 Speaker 1: so fast. We we will come back to that, um. 414 00:22:57,880 --> 00:22:59,800 Speaker 1: But there are plenty of other examples that have been 415 00:23:00,000 --> 00:23:03,240 Speaker 1: ideit of of animals showing some kind of sense of 416 00:23:03,280 --> 00:23:05,560 Speaker 1: what could be called numerous e or maybe would be 417 00:23:05,600 --> 00:23:09,760 Speaker 1: called appreciation of quantities if not numbers. For example, I 418 00:23:09,800 --> 00:23:13,320 Speaker 1: was I was looking at one study published in Philosophical 419 00:23:13,320 --> 00:23:17,199 Speaker 1: Transactions of the Royal Society b Biological Sciences by Rosa 420 00:23:17,280 --> 00:23:21,679 Speaker 1: Rugani that was studying, uh, the appreciation of differences in 421 00:23:21,800 --> 00:23:25,919 Speaker 1: quantities in day old chicks. So these are chickens they 422 00:23:26,000 --> 00:23:29,560 Speaker 1: have hatched for one day, and they can tell some 423 00:23:29,640 --> 00:23:34,879 Speaker 1: differences in quantities of food looking like pellet items. So 424 00:23:34,960 --> 00:23:36,960 Speaker 1: you know, in the dogs the chicks, this this is 425 00:23:36,960 --> 00:23:39,120 Speaker 1: not something they learned in school. It's not a cultural 426 00:23:39,160 --> 00:23:42,520 Speaker 1: invention here that this is playing on some innate capacity 427 00:23:42,600 --> 00:23:44,639 Speaker 1: they have. Now I found that really interesting what you 428 00:23:44,640 --> 00:23:48,320 Speaker 1: said earlier about about them accounting for the idea that 429 00:23:48,359 --> 00:23:51,400 Speaker 1: the dog might smell more meat in one direction as 430 00:23:51,400 --> 00:23:54,560 Speaker 1: opposed to the other. Uh and and and instead focusing 431 00:23:54,600 --> 00:23:57,880 Speaker 1: more on visual stimuli. And then perhaps this is something 432 00:23:57,960 --> 00:24:00,760 Speaker 1: to get into in the study for sure? By is 433 00:24:00,840 --> 00:24:03,040 Speaker 1: that fair? I wonder it was something like a dog 434 00:24:03,280 --> 00:24:08,879 Speaker 1: who's who's um olfactory senses are far superior to that 435 00:24:09,000 --> 00:24:12,480 Speaker 1: of humans, like alter like if they are thinking based 436 00:24:12,640 --> 00:24:16,600 Speaker 1: on olfactory data as opposed to visual data, Like, aren't 437 00:24:16,600 --> 00:24:20,040 Speaker 1: we ultimately talking about the same thing? Well, I mean, 438 00:24:20,160 --> 00:24:23,080 Speaker 1: so that gets into something interesting about numbers. Right, So 439 00:24:23,160 --> 00:24:27,040 Speaker 1: a dog could maybe smell that one pile of meat 440 00:24:27,119 --> 00:24:30,720 Speaker 1: has more meat in it than another pile, But would 441 00:24:30,720 --> 00:24:33,400 Speaker 1: that involve numbers, Because so you could take like one 442 00:24:33,480 --> 00:24:36,440 Speaker 1: ounce of meat and cut it in half and that's 443 00:24:36,480 --> 00:24:38,639 Speaker 1: now like two pieces of meat, but it would be 444 00:24:38,640 --> 00:24:40,879 Speaker 1: the same mass of it, right, So you'd imagine it 445 00:24:40,880 --> 00:24:44,560 Speaker 1: would admit probably about the same amount of smell. But 446 00:24:44,640 --> 00:24:47,359 Speaker 1: it seems like the visual sense is especially useful for 447 00:24:47,480 --> 00:24:51,919 Speaker 1: distinguishing numbers of objects. You know. I don't know how 448 00:24:51,960 --> 00:24:53,960 Speaker 1: exactly that would change our understanding of the study, but 449 00:24:54,240 --> 00:24:56,119 Speaker 1: it is a good point, and it raises this interesting 450 00:24:56,200 --> 00:25:01,639 Speaker 1: question about gross quantity versus discreete numbers of quantity, you know, like, 451 00:25:01,680 --> 00:25:04,600 Speaker 1: doesn't make make a difference to a dog to have like, uh, 452 00:25:05,040 --> 00:25:07,800 Speaker 1: if it's the exact same weight of meat, but it's 453 00:25:07,840 --> 00:25:11,560 Speaker 1: cut into more pieces. Clearly, and this may be a 454 00:25:11,560 --> 00:25:14,919 Speaker 1: product of our numerical education. We're very primed to think 455 00:25:14,960 --> 00:25:17,280 Speaker 1: about numbers of pieces of something, you know, which is 456 00:25:17,320 --> 00:25:19,520 Speaker 1: why it seems like it's better to get like more 457 00:25:19,520 --> 00:25:23,359 Speaker 1: smaller pieces of candy than one big piece of candy, right, Yeah, 458 00:25:23,400 --> 00:25:25,600 Speaker 1: I mean candy being key, I guess because you know, 459 00:25:25,760 --> 00:25:28,800 Speaker 1: also candy plays into some of these experiments with humans, 460 00:25:28,800 --> 00:25:30,919 Speaker 1: which we'll get into in a bit here. But like 461 00:25:31,000 --> 00:25:33,280 Speaker 1: you think about the like the chocolate bar that you 462 00:25:33,359 --> 00:25:37,040 Speaker 1: get and it already has the divisions you know, mapped out, uh, 463 00:25:37,240 --> 00:25:39,600 Speaker 1: so that you can be completely fair about how how 464 00:25:39,600 --> 00:25:42,000 Speaker 1: the pieces are broken up. This is a no cheat 465 00:25:42,040 --> 00:25:45,320 Speaker 1: candy bar. Yeah. But anyway, I also wanted to mention 466 00:25:45,359 --> 00:25:49,600 Speaker 1: that there is research also in human babies for evidence 467 00:25:49,640 --> 00:25:53,000 Speaker 1: of a biologically endowed number, since that has not learned 468 00:25:53,040 --> 00:25:56,600 Speaker 1: through culture. And so for example, in his article, Philip 469 00:25:56,640 --> 00:26:00,119 Speaker 1: Ball sites a cognitive neuroscientists named Daniel and Sorry the 470 00:26:00,200 --> 00:26:05,040 Speaker 1: University of Western Ontario in London, Canada, and on Sarry 471 00:26:05,160 --> 00:26:08,520 Speaker 1: says quote, studies with newborns and infants show that if 472 00:26:08,560 --> 00:26:11,760 Speaker 1: you show them eight dots repeatedly and then change it 473 00:26:11,800 --> 00:26:15,720 Speaker 1: to sixteen dots, areas in the right parietal cortex of 474 00:26:15,720 --> 00:26:19,520 Speaker 1: the brain respond to a change in numerosity. This response 475 00:26:19,560 --> 00:26:23,560 Speaker 1: is very similar in adults and this this might not 476 00:26:23,600 --> 00:26:25,720 Speaker 1: be exactly what it seems we can come back to 477 00:26:25,800 --> 00:26:29,000 Speaker 1: this later, but that's at least sort of a baseline finding, 478 00:26:29,359 --> 00:26:31,239 Speaker 1: and there are plenty of people who adhere to this 479 00:26:31,320 --> 00:26:34,920 Speaker 1: view and interpret this uh this evidence favorably. For example, 480 00:26:35,000 --> 00:26:38,800 Speaker 1: Ball sites a researcher named Andreas Nieder who is a 481 00:26:38,800 --> 00:26:42,800 Speaker 1: neuroscientist at the University of Tubingen in Germany, and actually 482 00:26:42,880 --> 00:26:45,560 Speaker 1: Needer recited in both of the articles I mentioned earlier, 483 00:26:46,119 --> 00:26:49,879 Speaker 1: but this researcher argues that the neuroscience helps support the 484 00:26:49,920 --> 00:26:53,040 Speaker 1: idea that human number since is innate and a product 485 00:26:53,040 --> 00:26:56,720 Speaker 1: of biological evolution rather than just culture. And one big 486 00:26:56,760 --> 00:27:01,280 Speaker 1: clue here is the is the brain imaging showing similarities 487 00:27:01,280 --> 00:27:05,640 Speaker 1: between what happens when non human animals and babies process 488 00:27:05,760 --> 00:27:09,600 Speaker 1: quantities in the brain and when adult humans process quantities 489 00:27:09,600 --> 00:27:12,360 Speaker 1: and the numbers in the brain, And so Neater would 490 00:27:12,440 --> 00:27:15,960 Speaker 1: argue that the similarity in the biological substrate here points 491 00:27:16,000 --> 00:27:19,960 Speaker 1: to an innate biological capacity that you've got some number meat. 492 00:27:20,440 --> 00:27:22,520 Speaker 1: And this debate has actually been going on for quite 493 00:27:22,560 --> 00:27:24,520 Speaker 1: some time. I think there's sort of a revival and 494 00:27:24,640 --> 00:27:27,760 Speaker 1: interest in it with some recent research that's made coming out, 495 00:27:27,800 --> 00:27:30,920 Speaker 1: but people have been talking about this question for a while. Yeah, 496 00:27:30,920 --> 00:27:33,160 Speaker 1: I mean to the point where I mean I feel 497 00:27:33,160 --> 00:27:35,560 Speaker 1: like it would be difficult. Like sometimes when we're discussing 498 00:27:35,560 --> 00:27:38,359 Speaker 1: two sides of a given debate, we can sort of 499 00:27:38,440 --> 00:27:42,240 Speaker 1: easily point to like the key papers, the key studies 500 00:27:42,760 --> 00:27:44,840 Speaker 1: um or or we just or or just you know, 501 00:27:44,880 --> 00:27:46,960 Speaker 1: pick a handful. And I feel like this is one 502 00:27:47,000 --> 00:27:48,840 Speaker 1: of those situations where you, yeah, you just have kind 503 00:27:48,840 --> 00:27:52,399 Speaker 1: of like ebbs and flows of of of as far 504 00:27:52,440 --> 00:27:54,840 Speaker 1: as the whole research goes. But uh, yeah, like as 505 00:27:54,840 --> 00:27:58,080 Speaker 1: far back as There's an article I was looking at 506 00:27:58,080 --> 00:28:01,800 Speaker 1: it I found rather helpful by Robert schwartz um discussing 507 00:28:01,840 --> 00:28:05,240 Speaker 1: the debate, and this was in the Philosophy of Science journal, 508 00:28:05,280 --> 00:28:08,200 Speaker 1: and the article is titled is Mathematical Competence in eate? 509 00:28:08,920 --> 00:28:11,840 Speaker 1: And schwartz points out that, you know, some of the 510 00:28:11,840 --> 00:28:17,520 Speaker 1: the earlier principles before models, uh, the theseum the work 511 00:28:17,520 --> 00:28:21,960 Speaker 1: here relates to, uh, some published findings in the nineteen 512 00:28:22,040 --> 00:28:26,399 Speaker 1: seventies by Gelman and Galistel, and that they quote argue 513 00:28:26,400 --> 00:28:31,280 Speaker 1: that innate number of specific principles underlie children's ability to count. Okay, 514 00:28:31,320 --> 00:28:34,400 Speaker 1: so maybe we invent the words for numbers, but that 515 00:28:34,600 --> 00:28:37,240 Speaker 1: the the number since is already something in the brain 516 00:28:37,359 --> 00:28:41,760 Speaker 1: that they're innately harnessing. Right. But then a counter argument 517 00:28:41,800 --> 00:28:44,680 Speaker 1: that Schwartz mentions, uh, and this was one that that 518 00:28:45,000 --> 00:28:50,760 Speaker 1: he cites Karen c uh Fusion from Night, who argued 519 00:28:50,800 --> 00:28:54,120 Speaker 1: a principles after model, and the idea here would be 520 00:28:54,160 --> 00:28:58,960 Speaker 1: that children begin by mechanically repeating sequences of counting words, 521 00:28:59,400 --> 00:29:02,920 Speaker 1: and it it fields up from there um. And so 522 00:29:03,200 --> 00:29:06,560 Speaker 1: Schwartz goes from there, you know, in relatively short time. 523 00:29:07,040 --> 00:29:09,400 Speaker 1: Uh to discuss the divide as follows own to read 524 00:29:09,400 --> 00:29:11,800 Speaker 1: this quote because I thought it was pretty helpful quote. 525 00:29:11,960 --> 00:29:16,200 Speaker 1: In many discussions of mathematical cognition, the principles before model 526 00:29:16,280 --> 00:29:20,120 Speaker 1: is identified as a Nativist thesis and the principles after 527 00:29:20,200 --> 00:29:23,800 Speaker 1: model as non nativist. I believe this is a mistake. 528 00:29:24,160 --> 00:29:27,360 Speaker 1: For suppose the principles before model is correct, that children 529 00:29:27,440 --> 00:29:30,440 Speaker 1: understand the basis for counting before they are able to count, 530 00:29:30,720 --> 00:29:35,160 Speaker 1: and that this understanding guide's skill development. Nothing specifically mathematical 531 00:29:35,320 --> 00:29:38,760 Speaker 1: is thereby innate. A principles before model is a Nativist 532 00:29:38,800 --> 00:29:42,480 Speaker 1: thesis only if the how to count principles are themselves 533 00:29:42,520 --> 00:29:46,880 Speaker 1: not learned. Showing this, however, is not easy, so I 534 00:29:46,920 --> 00:29:48,800 Speaker 1: don't know I like that breakdown. I like the way 535 00:29:48,800 --> 00:29:53,240 Speaker 1: that he approaches uh, the divide if you will, Oh, 536 00:29:53,320 --> 00:29:56,320 Speaker 1: I see. Okay, So even if there is some underlying 537 00:29:56,360 --> 00:30:00,480 Speaker 1: capacity that's being harnessed um when when you are learning 538 00:30:00,520 --> 00:30:03,640 Speaker 1: to count, you would still have to show that the 539 00:30:03,720 --> 00:30:07,400 Speaker 1: underlying capacity was not itself something that had been learned 540 00:30:07,520 --> 00:30:12,640 Speaker 1: before the counting education took place. Yeah, Like, I mean, well, 541 00:30:12,680 --> 00:30:14,560 Speaker 1: one way that I was thinking about some of this 542 00:30:14,680 --> 00:30:16,880 Speaker 1: earlier was too was thinking about, like, okay, what happens 543 00:30:16,880 --> 00:30:19,800 Speaker 1: when I pick up a paint brush? You know, because 544 00:30:19,840 --> 00:30:22,600 Speaker 1: on one level, I have more or lessoning. You know this, 545 00:30:22,840 --> 00:30:25,360 Speaker 1: I have this innate ability where I can pick up 546 00:30:25,400 --> 00:30:29,000 Speaker 1: something and it and my body schema updates to incorporate it. 547 00:30:29,000 --> 00:30:31,360 Speaker 1: I mean that's just basic tool use that is, that 548 00:30:31,520 --> 00:30:34,880 Speaker 1: is something that that our our species has going for it. Right, 549 00:30:35,120 --> 00:30:36,920 Speaker 1: But that doesn't mean you can pick up a paint 550 00:30:36,920 --> 00:30:40,000 Speaker 1: brush and then uh you know, you know, reproduce the 551 00:30:40,240 --> 00:30:42,440 Speaker 1: works of Michaelangelo or what have you, or create just 552 00:30:42,520 --> 00:30:47,200 Speaker 1: anything of of you know, of of of usefulness. There 553 00:30:47,280 --> 00:30:49,880 Speaker 1: is a place where you cross the threshold of innate 554 00:30:49,920 --> 00:30:55,240 Speaker 1: ability and you get into um education and skill acquisition. Right. Well, 555 00:30:55,280 --> 00:30:56,960 Speaker 1: and I guess It's a good question in the case 556 00:30:56,960 --> 00:30:59,720 Speaker 1: of the paint brush, also, like what part of it 557 00:30:59,840 --> 00:31:02,040 Speaker 1: is the innate part? Like what what's the part that 558 00:31:02,200 --> 00:31:04,560 Speaker 1: is just what kind of animal you are? And what 559 00:31:04,720 --> 00:31:07,240 Speaker 1: is the part where your seat you're watching things that 560 00:31:07,320 --> 00:31:11,200 Speaker 1: other people have done and you've learned from them. Um, 561 00:31:11,240 --> 00:31:14,160 Speaker 1: there's a good distinction in that Phillip Ball article where 562 00:31:14,160 --> 00:31:19,520 Speaker 1: he talks about the example of tennis, you know, so, like, Uh, 563 00:31:19,560 --> 00:31:24,480 Speaker 1: nobody would seriously argue that we are biologically evolved to 564 00:31:24,600 --> 00:31:28,480 Speaker 1: play tennis, and yet of course tennis does make use 565 00:31:28,640 --> 00:31:32,000 Speaker 1: of tons of things that are biologically evolved. Good tennis 566 00:31:32,000 --> 00:31:34,680 Speaker 1: players make use of a range of capacities that probably 567 00:31:34,720 --> 00:31:39,800 Speaker 1: evolve based on their ancestral pressures, involving things like hunting 568 00:31:40,080 --> 00:31:45,600 Speaker 1: or searching the environment for movement or escape behaviors, perhaps throwing. 569 00:31:45,760 --> 00:31:48,720 Speaker 1: You know, so, like there were things that originally shaped 570 00:31:48,800 --> 00:31:51,760 Speaker 1: what our bodies are nervous systems and our muscles could do. 571 00:31:52,480 --> 00:31:55,080 Speaker 1: And that's not exactly what we're doing, but it's somehow 572 00:31:55,160 --> 00:31:58,880 Speaker 1: close enough that we can use those uh skills and 573 00:31:59,040 --> 00:32:03,520 Speaker 1: capacities for this highly artificial thing like tennis. Yeah, like 574 00:32:03,560 --> 00:32:06,680 Speaker 1: what is tennis? But hit thing with stick? Right, but 575 00:32:06,800 --> 00:32:09,720 Speaker 1: hit thing with stick that is taken to um a 576 00:32:09,800 --> 00:32:14,240 Speaker 1: very specific and advanced degree, um you know, with you know, 577 00:32:14,400 --> 00:32:16,560 Speaker 1: hitting things with stick is something innate ever since the 578 00:32:16,560 --> 00:32:19,840 Speaker 1: monolith came. But but you know, you could like take 579 00:32:20,080 --> 00:32:21,920 Speaker 1: like all the Olympics, like a lot of it kind 580 00:32:21,920 --> 00:32:23,320 Speaker 1: of well not all of it, but there's a lot 581 00:32:23,360 --> 00:32:25,640 Speaker 1: of stuff there that kind of comes down to hit 582 00:32:25,680 --> 00:32:28,040 Speaker 1: thing with stick, or do things with rock and or 583 00:32:28,160 --> 00:32:30,400 Speaker 1: do things with rock and stick. Yeah, there are very 584 00:32:30,400 --> 00:32:32,520 Speaker 1: few competitions there that you could say are just like 585 00:32:32,760 --> 00:32:35,959 Speaker 1: purely biologically adapted to though maybe things that are just 586 00:32:36,080 --> 00:32:39,640 Speaker 1: purely like running or jumping or wrestling or something like that. 587 00:32:39,680 --> 00:32:43,000 Speaker 1: But yeah, once you're involving, once you're involving rules and 588 00:32:43,040 --> 00:32:46,120 Speaker 1: a ball and all that, you're getting increasingly abstract away 589 00:32:46,160 --> 00:32:50,000 Speaker 1: from the ancestral environment. But but the environment is also 590 00:32:50,120 --> 00:32:52,360 Speaker 1: key here because, like you you pointed out earlier, like 591 00:32:52,400 --> 00:32:54,479 Speaker 1: it's not just a situation of you know, you pick 592 00:32:54,560 --> 00:32:57,000 Speaker 1: up the paintbrush and then you figure out in a 593 00:32:57,080 --> 00:32:59,800 Speaker 1: vacuum what to do with it. You're immersed in, you 594 00:33:00,240 --> 00:33:03,360 Speaker 1: in in a culture, in an environment in which it 595 00:33:03,440 --> 00:33:05,680 Speaker 1: is used in a particular way. You're seeing it used 596 00:33:05,680 --> 00:33:08,760 Speaker 1: in a particular way. Even if if and then um, 597 00:33:08,800 --> 00:33:11,440 Speaker 1: you know, there's probably going to be some level of 598 00:33:11,440 --> 00:33:16,320 Speaker 1: of of direction and education uh there as well. Uh 599 00:33:16,360 --> 00:33:18,920 Speaker 1: so that for instance, there was another treatment on this 600 00:33:19,000 --> 00:33:23,160 Speaker 1: by Baruti at all Um in a titled The Development 601 00:33:23,240 --> 00:33:25,719 Speaker 1: of Young Children's Early number in Operations Since and Its 602 00:33:25,760 --> 00:33:28,560 Speaker 1: Implications for Early Childhood Education from two thousand and six, 603 00:33:29,080 --> 00:33:32,720 Speaker 1: and they pointed out that you know that that a 604 00:33:32,800 --> 00:33:36,520 Speaker 1: young child's whatever their spontaneous number attention is, that's how 605 00:33:36,520 --> 00:33:39,640 Speaker 1: they defined its spontaneous number attention, it's then going to 606 00:33:39,720 --> 00:33:43,080 Speaker 1: be also affected by their age, by their language, by 607 00:33:43,080 --> 00:33:45,520 Speaker 1: their collective makeup. I mean, they're they're all these other 608 00:33:45,560 --> 00:33:48,160 Speaker 1: factors that come in. Yeah, of course that's true. And 609 00:33:48,160 --> 00:33:50,520 Speaker 1: so one thing that might be helpful for sorting this 610 00:33:50,560 --> 00:33:54,000 Speaker 1: out is looking at the question of what is it 611 00:33:54,160 --> 00:33:58,440 Speaker 1: that uh that typically non human animals and and babies 612 00:33:58,920 --> 00:34:01,960 Speaker 1: have not been docu minute to do in any known case, 613 00:34:02,120 --> 00:34:05,680 Speaker 1: that that can be done once you have a numerical education. 614 00:34:06,400 --> 00:34:08,959 Speaker 1: And uh, I think one of the important things here 615 00:34:09,280 --> 00:34:13,600 Speaker 1: is the ability to make fine distinctions between differences in 616 00:34:13,760 --> 00:34:18,160 Speaker 1: quantities of again more than a handful so animals of 617 00:34:18,200 --> 00:34:21,680 Speaker 1: all sorts with non symbolic quantitative senses might be able 618 00:34:21,719 --> 00:34:25,080 Speaker 1: to tell a difference between one and two, or between 619 00:34:25,160 --> 00:34:28,680 Speaker 1: two and three, or between three and five, and they 620 00:34:28,760 --> 00:34:31,360 Speaker 1: might be able to tell a difference between one hundred 621 00:34:31,440 --> 00:34:35,080 Speaker 1: and two hundred. But what seems really unique of humans 622 00:34:35,120 --> 00:34:38,120 Speaker 1: with a number of education is the ability to tell 623 00:34:38,239 --> 00:34:42,280 Speaker 1: the difference between something like twenty one and twenty two, 624 00:34:42,880 --> 00:34:45,400 Speaker 1: or the difference between a hundred and fifty and a 625 00:34:45,480 --> 00:34:48,719 Speaker 1: hundred and fifty three. And I do think the researchers 626 00:34:48,719 --> 00:34:53,360 Speaker 1: who favor the biological adaptation argument would would acknowledge this point, 627 00:34:53,520 --> 00:34:55,879 Speaker 1: that this seems to be a unique and different kind 628 00:34:55,920 --> 00:34:58,200 Speaker 1: of thing. So I guess this brings us to the 629 00:34:58,200 --> 00:35:01,200 Speaker 1: other camp of researchers, the ones who are more sympathetic 630 00:35:01,280 --> 00:35:04,400 Speaker 1: to the idea that that numerous e is in some 631 00:35:04,480 --> 00:35:08,319 Speaker 1: sense a cultural invention and it needs to be learned. Now, 632 00:35:08,320 --> 00:35:11,000 Speaker 1: there's one major figure in this area of research who 633 00:35:11,080 --> 00:35:13,279 Speaker 1: is mentioned in both of the articles I talked about 634 00:35:13,360 --> 00:35:16,040 Speaker 1: up top that that got me interested in the subject, 635 00:35:16,360 --> 00:35:19,799 Speaker 1: and it is the cognitive scientist Raphael Nuniez of the 636 00:35:19,880 --> 00:35:23,719 Speaker 1: University of California at San Diego. Now I knew his 637 00:35:23,840 --> 00:35:26,080 Speaker 1: name seemed familiar when I read it, so I was like, 638 00:35:26,120 --> 00:35:27,719 Speaker 1: I bet we've talked about him in the past. I 639 00:35:27,719 --> 00:35:29,960 Speaker 1: looked it up in our previous notes, and actually he 640 00:35:30,040 --> 00:35:33,520 Speaker 1: was involved in some of the cultural variance research on 641 00:35:33,719 --> 00:35:38,919 Speaker 1: pointing that we talked about in the Pointing episodes. Remember this, Rob, Yeah, 642 00:35:38,920 --> 00:35:41,200 Speaker 1: it was the study that found that while pointing with 643 00:35:41,280 --> 00:35:43,960 Speaker 1: the index finger is very common around the world, there 644 00:35:43,960 --> 00:35:47,600 Speaker 1: are some cultural and language groups that have a preference 645 00:35:47,680 --> 00:35:51,160 Speaker 1: for facial pointing, pointing often with the nose instead of 646 00:35:51,160 --> 00:35:54,319 Speaker 1: with the the index finger. And the specific example they 647 00:35:54,320 --> 00:35:56,720 Speaker 1: looked at was the you know, people of Papua New Guinea. 648 00:35:57,440 --> 00:35:59,560 Speaker 1: I remember that study was really interesting because it was 649 00:35:59,560 --> 00:36:02,480 Speaker 1: trying to find, well, what could be some possible explanations 650 00:36:02,520 --> 00:36:05,080 Speaker 1: why this, uh, why this one group of people, this 651 00:36:05,160 --> 00:36:08,560 Speaker 1: language group tends to prefer pointing with the nose instead 652 00:36:08,560 --> 00:36:11,120 Speaker 1: of with the hand, or at least a higher relative 653 00:36:11,120 --> 00:36:13,440 Speaker 1: frequency of pointing with the nose than you find in 654 00:36:13,480 --> 00:36:16,479 Speaker 1: other cultures and language groups. And there were a number 655 00:36:16,480 --> 00:36:18,759 Speaker 1: of possible explanations there. I didn't want to get into 656 00:36:18,800 --> 00:36:21,400 Speaker 1: all of them, but one that seemed interesting and perhaps 657 00:36:21,480 --> 00:36:25,319 Speaker 1: very relevant to today's topic was the possibility that it 658 00:36:25,400 --> 00:36:27,880 Speaker 1: could have something to do with the yup no language 659 00:36:28,480 --> 00:36:35,160 Speaker 1: having more geographically specific demonstratives than many other languages do. So, 660 00:36:35,280 --> 00:36:38,759 Speaker 1: for example, not just like this and that, which we 661 00:36:38,800 --> 00:36:41,880 Speaker 1: have in English, but versions of this and that that 662 00:36:42,120 --> 00:36:48,440 Speaker 1: encode more specific location information with quote uphill downhill distinctions 663 00:36:48,440 --> 00:36:52,120 Speaker 1: and a three way distance contrast. So imagine if you 664 00:36:52,160 --> 00:36:54,880 Speaker 1: had words for like this and that that sort of 665 00:36:54,920 --> 00:36:59,800 Speaker 1: included something akin to uh north south east west, nearer 666 00:37:00,040 --> 00:37:02,160 Speaker 1: further and that kind of thing. Would you need to 667 00:37:02,200 --> 00:37:04,880 Speaker 1: do as much pointing in your life? Oh, that's a 668 00:37:04,920 --> 00:37:07,239 Speaker 1: good point, or at least would you need to do 669 00:37:07,280 --> 00:37:10,480 Speaker 1: the kind of precise pointing that's achievable with the finger, 670 00:37:10,680 --> 00:37:13,480 Speaker 1: or would a more general kind of facial point or 671 00:37:13,560 --> 00:37:16,600 Speaker 1: nod in the direction be more suitable anyway, I remember. 672 00:37:16,920 --> 00:37:18,920 Speaker 1: So that was really interesting. But we're talking about the 673 00:37:18,920 --> 00:37:22,440 Speaker 1: same researcher here, Nunez, and he has an idea to 674 00:37:22,680 --> 00:37:25,880 Speaker 1: make sense of some of the research with animals and 675 00:37:25,920 --> 00:37:30,279 Speaker 1: babies showing some limited numerical distinctions they can make. And 676 00:37:30,400 --> 00:37:34,080 Speaker 1: his idea here is that of making a distinction between 677 00:37:34,200 --> 00:37:39,520 Speaker 1: numerical cognition and what he calls quantical cognition. So here 678 00:37:39,560 --> 00:37:42,680 Speaker 1: to read from Philip Ball's article and summarizing this quote, 679 00:37:43,120 --> 00:37:47,799 Speaker 1: the perceptual rough discrimination of stimuli differing in numerousness or 680 00:37:47,880 --> 00:37:51,040 Speaker 1: quantities seen in babies and other animals is what he 681 00:37:51,120 --> 00:37:55,000 Speaker 1: calls quantical cognition. The ability to compare a hundred and 682 00:37:55,040 --> 00:37:58,600 Speaker 1: fifty two and a hundred and fifty three items, in contrast, 683 00:37:59,040 --> 00:38:04,080 Speaker 1: is numerical cognition. Quantical cognition cannot scale up to numerical 684 00:38:04,160 --> 00:38:09,800 Speaker 1: cognition via biological evolution alone, Nuniaz said. And this seems 685 00:38:09,840 --> 00:38:13,480 Speaker 1: to correspond with the possibility that without education, to the contrary, 686 00:38:14,040 --> 00:38:18,920 Speaker 1: humans naturally tend to process quantities in terms of a 687 00:38:19,000 --> 00:38:23,839 Speaker 1: logarithmic scale rather than an arithmetic scale. Yeah, there there 688 00:38:23,880 --> 00:38:27,560 Speaker 1: was one study that I was looking at. There are 689 00:38:27,560 --> 00:38:29,600 Speaker 1: a lot of studies to deal with logarithmic thinking in 690 00:38:29,840 --> 00:38:32,640 Speaker 1: in infants, but I was just looking at a two 691 00:38:33,360 --> 00:38:36,880 Speaker 1: Duke Institute for Brain Science and study that found that 692 00:38:36,920 --> 00:38:39,759 Speaker 1: babies that were good at discerning between large and small 693 00:38:39,800 --> 00:38:42,640 Speaker 1: groups of items before learning to count, we're more likely 694 00:38:42,680 --> 00:38:45,360 Speaker 1: to do better with numbers in the future. And so 695 00:38:45,440 --> 00:38:47,880 Speaker 1: the idea here again is that there there's you know, 696 00:38:47,920 --> 00:38:50,400 Speaker 1: some sort of primitive number. Since that the acquisition of 697 00:38:50,520 --> 00:38:53,359 Speaker 1: numeracy and mathematics is built a top off. But even 698 00:38:53,400 --> 00:38:57,319 Speaker 1: that the researchers, they were quick to point out that 699 00:38:57,400 --> 00:38:59,960 Speaker 1: this doesn't mean you can totally predict an infants mathematic 700 00:39:00,040 --> 00:39:03,040 Speaker 1: called future off of this data, but rather that there's 701 00:39:03,080 --> 00:39:06,600 Speaker 1: some sort of cognitive overlap between the two. Yeah, and 702 00:39:06,640 --> 00:39:09,000 Speaker 1: I think there there probably is. But to explain the 703 00:39:09,040 --> 00:39:12,200 Speaker 1: difference more, we should say so the arithmetic scale is 704 00:39:12,239 --> 00:39:14,920 Speaker 1: the one that you learn in school. The arithmetic scale 705 00:39:15,080 --> 00:39:17,880 Speaker 1: is the one with a number line where each number 706 00:39:18,040 --> 00:39:22,120 Speaker 1: increases by one and is evenly spaced, So one fifty 707 00:39:22,200 --> 00:39:25,440 Speaker 1: one is more than one fifty, So when you picture 708 00:39:25,440 --> 00:39:28,320 Speaker 1: the number line, it's like that each plus one is 709 00:39:28,320 --> 00:39:32,400 Speaker 1: is evenly spaced. But under log arrhythmic cognition, in contrast, 710 00:39:32,480 --> 00:39:36,760 Speaker 1: the difference between numbers is about ratios rather than about 711 00:39:36,800 --> 00:39:41,680 Speaker 1: absolute magnitude, increasing one unit at a time. So under 712 00:39:41,760 --> 00:39:45,279 Speaker 1: log arrhythmic cognition, the difference between something like you know, 713 00:39:45,360 --> 00:39:48,600 Speaker 1: like one thousand and two thousand can be viewed as 714 00:39:48,680 --> 00:39:52,359 Speaker 1: similar to the difference between one and two, even though 715 00:39:52,400 --> 00:39:55,319 Speaker 1: on the arithmetic scale it's a thousand times more of 716 00:39:55,360 --> 00:39:58,000 Speaker 1: a difference, and you can you can again see this 717 00:39:58,080 --> 00:40:00,560 Speaker 1: kind of comes back to the coffee description from earlier, 718 00:40:00,600 --> 00:40:04,640 Speaker 1: like you know, on on on us. On a logarithmic level, 719 00:40:05,000 --> 00:40:07,440 Speaker 1: there's really what's the difference between a thousand and a 720 00:40:07,480 --> 00:40:10,000 Speaker 1: thousand and one? Right? And if and if you were 721 00:40:10,000 --> 00:40:13,120 Speaker 1: just dealing on an individual level, I mean, there's ultimately 722 00:40:13,120 --> 00:40:16,600 Speaker 1: no experiential difference between the two. But if you're dealing 723 00:40:16,600 --> 00:40:19,759 Speaker 1: in units of like a thousand things you know, like 724 00:40:20,480 --> 00:40:22,600 Speaker 1: and then then there is a real difference between a 725 00:40:22,640 --> 00:40:24,960 Speaker 1: thousand and a thousand and one, you know, or between 726 00:40:24,960 --> 00:40:29,160 Speaker 1: a thousand and you know. Well, this actually brings me 727 00:40:29,200 --> 00:40:30,880 Speaker 1: back to do you remember when we did the episode 728 00:40:30,920 --> 00:40:35,800 Speaker 1: on Fermi estimation? Uh, a slightly different thing, but so, uh, 729 00:40:35,880 --> 00:40:40,200 Speaker 1: you're a physicist like Enrico Fermi, you obviously need arithmetic 730 00:40:40,400 --> 00:40:43,600 Speaker 1: sense of numbers in order to do precise calculations to 731 00:40:43,640 --> 00:40:47,000 Speaker 1: do your science. But also Fermi was famous for being 732 00:40:47,120 --> 00:40:51,360 Speaker 1: good at estimating quantities when other whereas other people, you know, 733 00:40:51,400 --> 00:40:55,080 Speaker 1: other colleagues of his, who had very good arithmetic number sense, 734 00:40:55,200 --> 00:40:57,600 Speaker 1: might not be. He was really good at just looking 735 00:40:57,640 --> 00:41:00,439 Speaker 1: at something and guessing some huge number or that would 736 00:41:00,440 --> 00:41:03,239 Speaker 1: turn out to be actually quite accurate. And apparently a 737 00:41:03,280 --> 00:41:06,400 Speaker 1: lot of his reasoning was based on not getting bogged 738 00:41:06,400 --> 00:41:09,040 Speaker 1: down in particulars, but thinking about things in terms of 739 00:41:09,239 --> 00:41:13,279 Speaker 1: orders of magnitude, which actually seems closer to the log 740 00:41:13,400 --> 00:41:16,840 Speaker 1: rhythmic type consciousness. Maybe that kind of thing is really 741 00:41:16,880 --> 00:41:22,080 Speaker 1: good for fast and dirty estimation of meaningful quantities. Yeah, 742 00:41:22,600 --> 00:41:24,319 Speaker 1: But another way of putting it is that on the 743 00:41:24,400 --> 00:41:29,200 Speaker 1: log rhythmic scale, differences between numbers become smaller or less 744 00:41:29,239 --> 00:41:32,480 Speaker 1: important as the numbers increase. So you know, the difference 745 00:41:32,480 --> 00:41:35,160 Speaker 1: between one and two is huge, the difference between two 746 00:41:35,200 --> 00:41:37,799 Speaker 1: and three is still pretty big. Once you're getting into 747 00:41:37,800 --> 00:41:41,040 Speaker 1: the differences between twenty eight and twenty nine, these are 748 00:41:41,080 --> 00:41:44,760 Speaker 1: not very meaningful distinctions anymore. And there is some research 749 00:41:44,800 --> 00:41:48,400 Speaker 1: indicating that some people who live in hunter gatherer societies 750 00:41:48,480 --> 00:41:52,720 Speaker 1: today tend to conceive of quantities in a log rhythmic 751 00:41:52,800 --> 00:41:56,080 Speaker 1: sense rather than an arithmetic sense. And I think you 752 00:41:56,080 --> 00:41:58,600 Speaker 1: could make a very strong case that this way of 753 00:41:58,640 --> 00:42:01,880 Speaker 1: looking at numbers, the log of the version, is biologically 754 00:42:01,920 --> 00:42:06,239 Speaker 1: adaptive in a way that that arithmetic numerousy is not 755 00:42:06,400 --> 00:42:10,920 Speaker 1: necessarily so. Again, to read from balls article quote, attributing 756 00:42:10,960 --> 00:42:13,719 Speaker 1: more weight to the difference between small than between large 757 00:42:13,800 --> 00:42:16,760 Speaker 1: numbers makes good sense in the real world and fits 758 00:42:16,800 --> 00:42:20,600 Speaker 1: with what a researcher named Vim Fias says about judging 759 00:42:20,640 --> 00:42:24,040 Speaker 1: by difference ratios. A difference between families of two and 760 00:42:24,200 --> 00:42:28,440 Speaker 1: three people is of comparable significance in a household as 761 00:42:28,480 --> 00:42:31,400 Speaker 1: the difference between two hundred and three hundred people in 762 00:42:31,480 --> 00:42:34,720 Speaker 1: a tribe, while the distinction between tribes of a hundred 763 00:42:34,719 --> 00:42:38,560 Speaker 1: and fifty two and a hundred and fifty three is negligible. 764 00:42:39,200 --> 00:42:41,600 Speaker 1: And so I think this could be a very insightful 765 00:42:42,280 --> 00:42:44,480 Speaker 1: way of breaking through this issue. It seems to me 766 00:42:44,640 --> 00:42:50,239 Speaker 1: quite conceivable that logarithmic cognition is the baseline for reasoning 767 00:42:50,320 --> 00:42:53,880 Speaker 1: about quantities, is just sort of what our brains naturally do, 768 00:42:54,600 --> 00:42:58,080 Speaker 1: and that we have to harness that innate capacity for 769 00:42:58,080 --> 00:43:01,920 Speaker 1: for logarithmic thinking and retrain it to use the equally 770 00:43:02,040 --> 00:43:06,279 Speaker 1: spaced arithmetic number line through education in school, since that 771 00:43:06,360 --> 00:43:09,840 Speaker 1: arithmetic number line is useful for certain types of work, 772 00:43:09,880 --> 00:43:11,920 Speaker 1: work that we often end up getting trained for, like 773 00:43:11,960 --> 00:43:14,080 Speaker 1: if you need to be an engineer or an architect 774 00:43:14,200 --> 00:43:18,120 Speaker 1: or something. Yeah, And I think it's also worth worth 775 00:43:18,160 --> 00:43:21,680 Speaker 1: stressing that that the idea that say, a human infant 776 00:43:22,320 --> 00:43:25,760 Speaker 1: can engage in logarithmic thinking, like that's incredible, Like that's 777 00:43:25,840 --> 00:43:28,520 Speaker 1: that's I find that really amazing. I like, I don't 778 00:43:28,560 --> 00:43:30,920 Speaker 1: think the read on it should be if if that 779 00:43:31,040 --> 00:43:33,920 Speaker 1: is indeed the cut off, if that is the base 780 00:43:34,160 --> 00:43:37,480 Speaker 1: upon which the further you know, tower of numbers and 781 00:43:37,520 --> 00:43:40,879 Speaker 1: mathematics is built, Like, that's still really incredible. I think 782 00:43:40,920 --> 00:43:44,040 Speaker 1: that's that's that's amazing to think about the way that 783 00:43:44,120 --> 00:43:47,600 Speaker 1: the you know, that this developing mind is able to 784 00:43:47,600 --> 00:43:50,200 Speaker 1: to view the world and look at, you know, one 785 00:43:50,239 --> 00:43:52,960 Speaker 1: pile of marshmallows versus another. I know, I'm taking the 786 00:43:53,000 --> 00:43:56,839 Speaker 1: difficult um stance of babies are are are good as 787 00:43:56,880 --> 00:43:59,759 Speaker 1: opposed to babies are bad and dumb? Well, yeah, I 788 00:43:59,760 --> 00:44:02,480 Speaker 1: think one very important takeaway from this is that the 789 00:44:02,600 --> 00:44:06,320 Speaker 1: more log arrhythmic style of conceiving of numbers is in 790 00:44:06,719 --> 00:44:09,760 Speaker 1: no way an indication of like a lack of sophistication 791 00:44:09,920 --> 00:44:12,640 Speaker 1: or anything like that. Instead, it has to do with 792 00:44:12,760 --> 00:44:16,879 Speaker 1: what kinds of quantity concepts are useful for your way 793 00:44:16,880 --> 00:44:18,680 Speaker 1: of life, like what do you need to do to 794 00:44:18,760 --> 00:44:21,120 Speaker 1: get through a day? And for some ways of making 795 00:44:21,120 --> 00:44:24,480 Speaker 1: a living, arithmetic cognition may be more useful, but for 796 00:44:24,560 --> 00:44:27,800 Speaker 1: other ways of living, uh, a more approximate log arrhythmic 797 00:44:27,840 --> 00:44:30,040 Speaker 1: cognition might be more useful. So it's really just a 798 00:44:30,120 --> 00:44:32,400 Speaker 1: question of what do you need in order to do 799 00:44:32,440 --> 00:44:42,320 Speaker 1: what you do to survive than There's another thing Philip 800 00:44:42,320 --> 00:44:45,319 Speaker 1: Ball sites in this article that I'd read before but 801 00:44:45,880 --> 00:44:47,880 Speaker 1: I had forgotten about until now, which I thought was 802 00:44:47,880 --> 00:44:50,600 Speaker 1: pretty interesting. He talks about some of the research of 803 00:44:50,920 --> 00:44:55,040 Speaker 1: Jean Piage in the nineteen sixties that was about how 804 00:44:55,280 --> 00:44:59,479 Speaker 1: young children often instinctively use visual features of quantities rather 805 00:44:59,560 --> 00:45:03,440 Speaker 1: than splicit counting, in order to judge the magnitude of 806 00:45:03,440 --> 00:45:05,880 Speaker 1: a quantity. For example, if you're to ask a child 807 00:45:05,920 --> 00:45:08,239 Speaker 1: you know which group of marbles has more in it, 808 00:45:08,600 --> 00:45:11,320 Speaker 1: you take the same number of marbles and you line 809 00:45:11,320 --> 00:45:15,680 Speaker 1: them up widely spaced versus densely spaced. Young children will 810 00:45:15,719 --> 00:45:18,560 Speaker 1: tend to think that the group with wider spacing has 811 00:45:18,640 --> 00:45:20,960 Speaker 1: more marbles in it, even if they're the same number. 812 00:45:21,000 --> 00:45:22,879 Speaker 1: And I could be wrong about this, but I think 813 00:45:22,920 --> 00:45:25,760 Speaker 1: I recall when I was reading this that the studies 814 00:45:25,760 --> 00:45:28,200 Speaker 1: showed that the kids thought even if you just moved 815 00:45:28,320 --> 00:45:31,040 Speaker 1: the same number of marbles around right in front of 816 00:45:31,040 --> 00:45:33,239 Speaker 1: their eyes, they still thought when you spaced them out 817 00:45:33,280 --> 00:45:38,440 Speaker 1: there was more in them. Interesting. Yeah, this this reminds 818 00:45:38,440 --> 00:45:40,600 Speaker 1: me of of something that I've accused my child and 819 00:45:40,680 --> 00:45:43,000 Speaker 1: my cat off on many occasions. Not so much of 820 00:45:43,040 --> 00:45:45,640 Speaker 1: my keeping my child anymore more when he was younger, 821 00:45:45,640 --> 00:45:48,680 Speaker 1: but uh, the idea of crumb blindness, where once the 822 00:45:48,760 --> 00:45:51,879 Speaker 1: larger portions of a particular meal have been consumed, there 823 00:45:51,920 --> 00:45:53,960 Speaker 1: is an inability to realize that there is still a 824 00:45:53,960 --> 00:45:56,920 Speaker 1: substantial amount of food on the plate, albeit in smaller 825 00:45:56,960 --> 00:46:00,640 Speaker 1: spread out form. Um. I think the boy figured it out, 826 00:46:00,760 --> 00:46:03,400 Speaker 1: but the cat still seems clueless to this. Well. I 827 00:46:03,400 --> 00:46:06,360 Speaker 1: think it could also highlight something which is that, Um, 828 00:46:07,200 --> 00:46:09,480 Speaker 1: there's some indication I mentioned earlier that I was going 829 00:46:09,560 --> 00:46:13,280 Speaker 1: to come back to that that research indicating that babies 830 00:46:13,400 --> 00:46:15,920 Speaker 1: or maybe using what is sometimes believed to be a 831 00:46:16,040 --> 00:46:19,560 Speaker 1: number module in the brain when they're judging different quantities 832 00:46:19,560 --> 00:46:22,719 Speaker 1: of objects in their visual field. Uh. There was that 833 00:46:22,760 --> 00:46:26,200 Speaker 1: researcher Daniel and Sorry who I mentioned earlier, um who 834 00:46:26,360 --> 00:46:29,239 Speaker 1: who also is cited in this article talking about how 835 00:46:29,280 --> 00:46:32,799 Speaker 1: the neuroscience research into human infants actually became more complicated 836 00:46:32,840 --> 00:46:35,280 Speaker 1: as it went on, where he said that more recent 837 00:46:35,320 --> 00:46:40,560 Speaker 1: research has revealed some dissimilarities between the way that brains 838 00:46:40,640 --> 00:46:44,280 Speaker 1: process non symbolic numbers. So that would mean like something 839 00:46:44,320 --> 00:46:45,920 Speaker 1: that you can look at, you know, a number of 840 00:46:45,960 --> 00:46:49,839 Speaker 1: dots in your visual field, versus symbolic numbers, you know, 841 00:46:49,960 --> 00:46:53,040 Speaker 1: numbers that you're manipulating based on their symbols nine plus 842 00:46:53,080 --> 00:46:56,040 Speaker 1: five or something. And this more recent research has found 843 00:46:56,040 --> 00:46:59,320 Speaker 1: that they're not always correlated. Uh, to read part of 844 00:46:59,320 --> 00:47:02,240 Speaker 1: a quote from an sorry here that challenges the notion 845 00:47:02,280 --> 00:47:06,080 Speaker 1: that the brain mechanisms for processing culturally invented number symbols 846 00:47:06,120 --> 00:47:09,680 Speaker 1: maps onto the non symbolic number system. I think these 847 00:47:09,680 --> 00:47:13,520 Speaker 1: systems are not as closely related as we thought. So 848 00:47:13,560 --> 00:47:16,120 Speaker 1: maybe the brain is actually doing something importantly kind of 849 00:47:16,160 --> 00:47:20,960 Speaker 1: different when it's judging quantities based on you know, visual cues, 850 00:47:21,000 --> 00:47:24,399 Speaker 1: like looking at a number of physical objects, versus when 851 00:47:24,440 --> 00:47:29,560 Speaker 1: it is manipulating abstract numbers through learned symbols. But this 852 00:47:29,840 --> 00:47:32,000 Speaker 1: makes you wonder about, like, is it possible that a 853 00:47:32,040 --> 00:47:36,319 Speaker 1: crucial element in number sense is actually language or some 854 00:47:36,560 --> 00:47:40,200 Speaker 1: form of language. Does having a naming system for numbers 855 00:47:40,400 --> 00:47:43,319 Speaker 1: unlock types of numeracy that aren't really there if you 856 00:47:43,400 --> 00:47:46,000 Speaker 1: don't have that naming system, Yeah, I mean it kind 857 00:47:46,000 --> 00:47:47,480 Speaker 1: of comes back to what I said earlier about the 858 00:47:47,520 --> 00:47:49,920 Speaker 1: cat right, if without the word for cat. You can't 859 00:47:50,320 --> 00:47:55,960 Speaker 1: engage in more complex uses of its basic catinus. You know, 860 00:47:56,040 --> 00:48:00,600 Speaker 1: I can't. I can't make comparisons and analogy and metaphors 861 00:48:00,600 --> 00:48:03,719 Speaker 1: regarding the cat. Uh if I don't have some sort 862 00:48:03,760 --> 00:48:06,680 Speaker 1: of word for it. Right, Well, this here you go. 863 00:48:06,840 --> 00:48:08,800 Speaker 1: Maybe this will tie a way back to our first 864 00:48:08,840 --> 00:48:12,920 Speaker 1: Monster episode. Could you imagine a cat human hybrid if 865 00:48:12,960 --> 00:48:16,440 Speaker 1: you didn't have a word for cat's? Having a word 866 00:48:16,680 --> 00:48:19,680 Speaker 1: for these animals allow you to start mixing and matching 867 00:48:19,719 --> 00:48:21,600 Speaker 1: them in a way that you wouldn't if you didn't 868 00:48:21,640 --> 00:48:27,400 Speaker 1: have the word. Yeah, doing theeomorphic arithmetic, Yeah, I don't know, 869 00:48:27,480 --> 00:48:29,840 Speaker 1: just a weird idea. And now that I think about it, 870 00:48:29,880 --> 00:48:32,560 Speaker 1: maybe I'm doubting that. Actually, surely you could picture that 871 00:48:32,600 --> 00:48:35,640 Speaker 1: with it Well, I don't know who knows what Well, 872 00:48:35,680 --> 00:48:38,040 Speaker 1: I'm doubting myself every which way. Now, Well, but I 873 00:48:38,080 --> 00:48:40,799 Speaker 1: guess that I guess on one level, Yes, if you're 874 00:48:40,920 --> 00:48:42,839 Speaker 1: you're a human being, you're standing next to a human 875 00:48:42,880 --> 00:48:46,040 Speaker 1: being and you see the lion, I'm I'm gonna be 876 00:48:46,120 --> 00:48:48,640 Speaker 1: generous enough to imagine that that even the ancient and 877 00:48:48,840 --> 00:48:53,040 Speaker 1: imaginative force was enough to put the two together. But then, 878 00:48:53,360 --> 00:48:56,880 Speaker 1: for that combination then itself to have some sort of 879 00:48:56,960 --> 00:49:00,880 Speaker 1: value that can be easily transmitted than it helps to 880 00:49:00,920 --> 00:49:03,839 Speaker 1: have those two words, right, because then you can say, like, 881 00:49:04,200 --> 00:49:08,320 Speaker 1: imagine the wolfman or you know, imagine the Lyon man, 882 00:49:08,760 --> 00:49:10,720 Speaker 1: as opposed to saying, hey, you ever seen that credit 883 00:49:10,719 --> 00:49:12,839 Speaker 1: out there that you know, that big, the big scary one, 884 00:49:12,960 --> 00:49:16,000 Speaker 1: that that that you know, I don't eight Tharg the 885 00:49:16,000 --> 00:49:19,680 Speaker 1: other day, Well imagine that, but with Tharg's head no 886 00:49:19,880 --> 00:49:22,360 Speaker 1: instead of its own. You know, it just becomes more complicated. 887 00:49:22,360 --> 00:49:23,880 Speaker 1: Try and put the two together. But if you have 888 00:49:23,920 --> 00:49:27,040 Speaker 1: the words, then you have the like, then the combination 889 00:49:27,080 --> 00:49:30,200 Speaker 1: of the two words, the hybrid is also so much 890 00:49:30,239 --> 00:49:34,239 Speaker 1: more easily um conveyed to other people and discussed and 891 00:49:34,400 --> 00:49:38,680 Speaker 1: used and has kind of weight all its own. Yeah, 892 00:49:38,800 --> 00:49:40,399 Speaker 1: we may have to come back to this, but also 893 00:49:40,520 --> 00:49:42,680 Speaker 1: back to numbers, because I think there's another way of 894 00:49:42,680 --> 00:49:45,000 Speaker 1: looking at this question that that we'll have to revisit 895 00:49:45,000 --> 00:49:48,200 Speaker 1: in a future episode, which is, do we have any 896 00:49:48,239 --> 00:49:51,160 Speaker 1: evidence that could answer the question of how in fact 897 00:49:51,320 --> 00:49:55,880 Speaker 1: our prehistoric ancestors first started using the concept of numbers 898 00:49:55,960 --> 00:49:59,120 Speaker 1: and displaying signs of a number since as opposed to 899 00:49:59,200 --> 00:50:02,680 Speaker 1: just a quantity sense, uh and if there are signs 900 00:50:02,680 --> 00:50:05,360 Speaker 1: of that, can that shed any light on this question? 901 00:50:05,560 --> 00:50:07,040 Speaker 1: I think we will come back to that in a 902 00:50:07,200 --> 00:50:10,839 Speaker 1: future episode, maybe a very near future episode. Yeah, yeah, 903 00:50:10,840 --> 00:50:12,680 Speaker 1: I mean it might. I was we were talking about 904 00:50:12,680 --> 00:50:14,520 Speaker 1: this earlier. Should we do apart one in a part two? 905 00:50:14,600 --> 00:50:16,439 Speaker 1: Maybe it is ultimately a part one in part two 906 00:50:16,480 --> 00:50:19,799 Speaker 1: instead of like two related standalone episodes. I don't know, 907 00:50:20,280 --> 00:50:23,040 Speaker 1: but but yeah, we'll think it will definitely be back 908 00:50:23,200 --> 00:50:26,160 Speaker 1: to discuss this more like ultimately, Like it's kind of 909 00:50:26,160 --> 00:50:29,719 Speaker 1: the invention of numbers? Uh what? What what does it mean? 910 00:50:29,800 --> 00:50:32,720 Speaker 1: And then where is the invention taking place? And what cultures, 911 00:50:32,719 --> 00:50:35,319 Speaker 1: what different systems, etcetera. And what can we what can 912 00:50:35,400 --> 00:50:38,799 Speaker 1: we learn from those? Yeah, I'm jazzed jazz for numbers. Man, 913 00:50:40,000 --> 00:50:43,200 Speaker 1: I'm gonna have one more small child story. And I 914 00:50:43,280 --> 00:50:45,719 Speaker 1: don't know how this relates to anything we've discussed. Maybe 915 00:50:45,719 --> 00:50:51,600 Speaker 1: it doesn't. Um, but when my son was either less 916 00:50:51,600 --> 00:50:53,239 Speaker 1: than two or more than two, I'm not sure how 917 00:50:53,239 --> 00:50:56,279 Speaker 1: old he was, he was approximately a two year old, 918 00:50:56,320 --> 00:50:59,480 Speaker 1: I think, Um. I remember there would be these situations 919 00:50:59,480 --> 00:51:01,360 Speaker 1: where he would have a snack or a meal or 920 00:51:01,400 --> 00:51:04,680 Speaker 1: something generally a snack situation or some sort of like 921 00:51:04,719 --> 00:51:09,480 Speaker 1: shared um uh you know, plate situation, and he would 922 00:51:09,520 --> 00:51:13,120 Speaker 1: be excited about eating something and then if if if I, 923 00:51:13,200 --> 00:51:15,560 Speaker 1: as an adult, were to come up and have a 924 00:51:15,560 --> 00:51:17,880 Speaker 1: piece of it, like to take a cheerio for myself 925 00:51:17,960 --> 00:51:20,840 Speaker 1: or what have you or a chip. Uh there were 926 00:51:20,880 --> 00:51:23,480 Speaker 1: on more than one occasion, he would look dejected and 927 00:51:23,520 --> 00:51:27,760 Speaker 1: he would say why you eat it all? And uh? 928 00:51:27,800 --> 00:51:30,279 Speaker 1: And I keep coming back to that, like it's like 929 00:51:30,320 --> 00:51:33,040 Speaker 1: a you know, some level of like food and security 930 00:51:33,160 --> 00:51:35,080 Speaker 1: or just like or this, you know, how does it 931 00:51:35,120 --> 00:51:38,640 Speaker 1: relate to our discussing of of uh you know, of 932 00:51:38,680 --> 00:51:41,640 Speaker 1: you know, thinking about quantities and numbers, because like clearly 933 00:51:41,640 --> 00:51:44,560 Speaker 1: I didn't eat at all, and never did I come 934 00:51:44,600 --> 00:51:46,640 Speaker 1: around and just eat all of the food that was 935 00:51:46,680 --> 00:51:49,920 Speaker 1: allocated to him. Uh oh, this seems very related to 936 00:51:49,920 --> 00:51:55,680 Speaker 1: the general psychological phenomenon of um of totalizing the single experience. 937 00:51:55,800 --> 00:51:59,200 Speaker 1: You ever notice, how like if you if you do 938 00:51:59,400 --> 00:52:03,359 Speaker 1: something one time that somebody doesn't like, sometimes they'll be like, 939 00:52:03,400 --> 00:52:05,960 Speaker 1: why are you always doing this? But in fact you 940 00:52:06,000 --> 00:52:08,560 Speaker 1: did it once, But if like they really didn't like it, 941 00:52:08,560 --> 00:52:13,960 Speaker 1: it feels like it's always happening, right right, Yeah, So anyway, 942 00:52:13,960 --> 00:52:15,480 Speaker 1: like I said, that may have may have no connection 943 00:52:15,480 --> 00:52:18,080 Speaker 1: to anything we've discussed here, but I've been thinking about 944 00:52:18,120 --> 00:52:19,600 Speaker 1: it in the background the whole time, so I had 945 00:52:19,640 --> 00:52:21,960 Speaker 1: to share it. Why you eat them all? All Right, 946 00:52:22,040 --> 00:52:24,319 Speaker 1: We're gonna go and close it out for today, but 947 00:52:24,360 --> 00:52:27,160 Speaker 1: we'll be back with more discussion of numbers and more 948 00:52:27,160 --> 00:52:31,319 Speaker 1: discussion of various other topics in the immediate future. In 949 00:52:31,360 --> 00:52:33,040 Speaker 1: the meantime, if you would like to listen to other 950 00:52:33,040 --> 00:52:35,200 Speaker 1: episodes of Stuff to Blow Your Mind, you can find 951 00:52:35,200 --> 00:52:38,240 Speaker 1: them wherever you get your podcasts.

That's the day that we 960 00:53:03,160 --> 00:53:05,719 Speaker 1: set most of the science and culture aside and we 961 00:53:05,840 --> 00:53:09,760 Speaker 1: just discussed some manner of b movie or weird film 962 00:53:09,880 --> 00:53:12,480 Speaker 1: or whatever. It happens to be huge things. As always 963 00:53:12,480 --> 00:53:15,279 Speaker 1: to our excellent audio producer Seth Nicholas Johnson.
