1 00:00:03,040 --> 00:00:07,000 Speaker 1: Welcome to Stuff to Blow Your Mind, a production of iHeartRadio. 2 00:00:12,920 --> 00:00:15,120 Speaker 2: Hey, welcome to Stuff to Blow your Mind. 3 00:00:15,280 --> 00:00:18,480 Speaker 3: My name is Robert Lamb and I am Joe McCormick. 4 00:00:18,640 --> 00:00:21,560 Speaker 3: And Hey, it is no longer October. But is this 5 00:00:21,600 --> 00:00:23,960 Speaker 3: still a topic that we planned on doing in October 6 00:00:23,960 --> 00:00:27,360 Speaker 3: and never got to Possibly. We'll let you guess if 7 00:00:27,400 --> 00:00:28,319 Speaker 3: that is the case or not. 8 00:00:29,000 --> 00:00:31,240 Speaker 2: Yeah, And you might be like, I don't know, Joe 9 00:00:31,280 --> 00:00:33,800 Speaker 2: and Robert, I don't know if I wont Halloween content 10 00:00:33,920 --> 00:00:37,080 Speaker 2: and the early part of November, shouldn't we be doing 11 00:00:37,120 --> 00:00:42,239 Speaker 2: Christmas content now? No, absolutely not. There will be Christmas 12 00:00:42,240 --> 00:00:44,760 Speaker 2: content in due time, but it will not be this month. 13 00:00:45,240 --> 00:00:48,720 Speaker 2: It'll barely be next month. So you're getting more Halloween 14 00:00:48,760 --> 00:00:50,400 Speaker 2: content whether you want it or not. 15 00:00:51,000 --> 00:00:53,120 Speaker 3: Are your Halloween decorations still up or do you get 16 00:00:53,159 --> 00:00:53,760 Speaker 3: them down yet? 17 00:00:54,080 --> 00:00:56,880 Speaker 2: We took them down over the weekend, but the jack 18 00:00:56,920 --> 00:01:00,880 Speaker 2: O Landin's are still out there. They haven't turn to 19 00:01:00,960 --> 00:01:03,120 Speaker 2: jelly yet, but I'm having to give them the tap 20 00:01:03,520 --> 00:01:07,679 Speaker 2: test every day. If they jiggle, then it's dangerously close 21 00:01:07,720 --> 00:01:09,760 Speaker 2: and I have to get them to the backyard and 22 00:01:10,040 --> 00:01:10,800 Speaker 2: spill them there. 23 00:01:11,000 --> 00:01:15,039 Speaker 3: I know exactly what you're saying. We have squirrels very 24 00:01:15,160 --> 00:01:18,319 Speaker 3: slowly eating our pumpkins. It's like they take one bite 25 00:01:18,319 --> 00:01:19,400 Speaker 3: out of them every day. 26 00:01:20,440 --> 00:01:22,280 Speaker 2: It's weird. We have plenty of squirrels around here, but 27 00:01:22,319 --> 00:01:24,640 Speaker 2: I don't think they ever messed with the pumpkins. But 28 00:01:25,600 --> 00:01:28,199 Speaker 2: it has been I feel like more people are chronicling 29 00:01:28,280 --> 00:01:31,160 Speaker 2: the decay and or consumption of their jack lanterns and 30 00:01:31,200 --> 00:01:33,720 Speaker 2: pumpkins this year, and it's been nice to watch. 31 00:01:34,000 --> 00:01:36,840 Speaker 3: I'm curious why just the like one bite and run away, 32 00:01:36,959 --> 00:01:40,000 Speaker 3: Like it can't be that delicious if they don't stay 33 00:01:40,080 --> 00:01:41,360 Speaker 3: to take a few more bites. 34 00:01:42,200 --> 00:01:45,959 Speaker 2: Unless it's you know, just gnawing. It's gnawing action. I'm 35 00:01:45,959 --> 00:01:46,399 Speaker 2: not sure. 36 00:01:46,680 --> 00:01:49,720 Speaker 3: But Okay, what was this Halloween related topic that we 37 00:01:49,760 --> 00:01:51,880 Speaker 3: didn't get to in October and they're covering now. 38 00:01:51,960 --> 00:01:56,120 Speaker 2: It's headlessness, Yeah, which ties in nicely with the idea 39 00:01:56,120 --> 00:01:59,320 Speaker 2: of jackal lanterns. I mean, these two concepts are are 40 00:01:59,400 --> 00:02:02,480 Speaker 2: connected in many ways. Yeah, we're going to discuss the 41 00:02:02,560 --> 00:02:07,800 Speaker 2: idea of headless entities, mostly in the human imagination, but 42 00:02:08,680 --> 00:02:11,360 Speaker 2: it probably makes sense to think about what's lacking in 43 00:02:11,440 --> 00:02:14,040 Speaker 2: these fantastic creatures and what we tend to take for granted. 44 00:02:14,480 --> 00:02:16,720 Speaker 2: It's we're going to get into just the concept of 45 00:02:17,120 --> 00:02:20,160 Speaker 2: why do creatures have heads? What is a head? Even 46 00:02:20,680 --> 00:02:23,040 Speaker 2: it's easy to just take that whole idea for granted, 47 00:02:24,320 --> 00:02:26,760 Speaker 2: because I mean, the basics I think are pretty obvious, 48 00:02:26,919 --> 00:02:29,079 Speaker 2: and you know, we have to stop and look them 49 00:02:29,080 --> 00:02:31,320 Speaker 2: in the mirror and realize. A head is the top 50 00:02:31,400 --> 00:02:35,120 Speaker 2: or front part of an organism, the upper or anterior 51 00:02:35,160 --> 00:02:38,640 Speaker 2: division of the animal body that contains the brain, most 52 00:02:38,639 --> 00:02:41,320 Speaker 2: of the sense organs, and the mouth. It is the 53 00:02:41,360 --> 00:02:45,639 Speaker 2: communication array as we've described it many times before. It's 54 00:02:45,680 --> 00:02:48,359 Speaker 2: the matter consumer, and it's also the nerve center of 55 00:02:48,400 --> 00:02:49,079 Speaker 2: the organism. 56 00:02:49,320 --> 00:02:52,639 Speaker 3: Now, most of the animals you can probably think of 57 00:02:52,639 --> 00:02:56,080 Speaker 3: off the top of your head do have heads, but 58 00:02:56,240 --> 00:02:59,720 Speaker 3: actually a head is not a necessary part of what 59 00:02:59,760 --> 00:03:02,840 Speaker 3: it means to be an animal. There are animals without heads, 60 00:03:03,120 --> 00:03:06,519 Speaker 3: So that raises the question of why do certain animals 61 00:03:06,560 --> 00:03:09,320 Speaker 3: have heads and not others? What causes this difference? 62 00:03:10,240 --> 00:03:12,919 Speaker 2: Yeah, we have to realize that heads emerge in organisms 63 00:03:12,960 --> 00:03:15,639 Speaker 2: over the course of evolutionary time and a process referred 64 00:03:15,680 --> 00:03:20,160 Speaker 2: to as cephalization, during which the mouth, sense organs and 65 00:03:20,240 --> 00:03:23,240 Speaker 2: nerve ganglia moved toward the front or what would we 66 00:03:23,280 --> 00:03:25,240 Speaker 2: would come to think of at the front of the creatures, 67 00:03:25,480 --> 00:03:29,720 Speaker 2: resulting in head morphology and the emergence of complex brains 68 00:03:30,160 --> 00:03:36,560 Speaker 2: and arthropods, cephalopod mollus and invertebrates. So these organisms tend 69 00:03:36,560 --> 00:03:42,320 Speaker 2: to be cephalized or semi cephalized. And would that mean 70 00:03:42,360 --> 00:03:45,000 Speaker 2: that a creature in fantasy that has lost its head 71 00:03:45,000 --> 00:03:51,640 Speaker 2: and continues to move around and act and behave is decephalized. 72 00:03:52,200 --> 00:03:54,040 Speaker 3: Well, I think that would be the term. The head 73 00:03:54,080 --> 00:03:57,680 Speaker 3: is removed, a thing is decephalized. But whether or not 74 00:03:57,720 --> 00:04:00,040 Speaker 3: a thing can continue to act without its head, it 75 00:04:00,200 --> 00:04:04,200 Speaker 3: probably depends on the degree to which it was originally 76 00:04:04,400 --> 00:04:09,160 Speaker 3: cephalized as a matter of its innate anatomy. I'll get 77 00:04:09,200 --> 00:04:12,240 Speaker 3: back to that in a few minutes. Actually, So I 78 00:04:12,280 --> 00:04:14,920 Speaker 3: was thinking about this, and it probably helps to put 79 00:04:15,080 --> 00:04:22,680 Speaker 3: cephalization within the broader evolutionary history of bilateral animals or bilatarians. 80 00:04:22,839 --> 00:04:25,720 Speaker 3: These are animals that have a left side and a 81 00:04:25,839 --> 00:04:29,240 Speaker 3: right side of the body that are roughly symmetrical, that 82 00:04:29,360 --> 00:04:32,560 Speaker 3: are mirror images of each other. So we are bilatarians, 83 00:04:32,800 --> 00:04:35,279 Speaker 3: and again, most of the animals you can think of off 84 00:04:35,160 --> 00:04:38,360 Speaker 3: the top of your head are bilatarians. The symmetry does 85 00:04:38,400 --> 00:04:41,919 Speaker 3: not have to be exact. It refers to the overall 86 00:04:42,040 --> 00:04:45,679 Speaker 3: body plan and how the animal develops in its earliest 87 00:04:45,680 --> 00:04:48,520 Speaker 3: phases of growth. So even in the case of animals 88 00:04:48,520 --> 00:04:53,040 Speaker 3: that happen to have evolved wildly asymmetrical features. One example 89 00:04:53,080 --> 00:04:55,920 Speaker 3: we've talked about on the show before is male fiddler crabs, 90 00:04:56,000 --> 00:04:59,279 Speaker 3: which have one claw that's much bigger than the other, 91 00:04:59,320 --> 00:05:02,000 Speaker 3: in some cases half of the crab's body weight, So 92 00:05:02,600 --> 00:05:04,800 Speaker 3: you know, roughly on the scale of a human with 93 00:05:04,880 --> 00:05:08,000 Speaker 3: one regular sized hand and then another hand that's four 94 00:05:08,040 --> 00:05:11,880 Speaker 3: feet in diameter and weighs eighty pounds, even that animal 95 00:05:12,120 --> 00:05:15,600 Speaker 3: is a bilatarian because the animal's body plan has bilateral 96 00:05:15,640 --> 00:05:19,120 Speaker 3: symmetry overall, with the exception of the claw, And it's 97 00:05:19,160 --> 00:05:22,920 Speaker 3: also a question of its evolutionary clade. It is descended 98 00:05:23,080 --> 00:05:28,160 Speaker 3: from the evolutionary clade of bilateral animals. So bilateral symmetry 99 00:05:28,240 --> 00:05:30,919 Speaker 3: is not just a feature of an animal body, but 100 00:05:31,000 --> 00:05:34,440 Speaker 3: a particular branch on the evolutionary tree, going back to 101 00:05:34,480 --> 00:05:37,640 Speaker 3: a common ancestor. As I was saying a minute ago, 102 00:05:38,080 --> 00:05:41,480 Speaker 3: though most of the animals you can think of are bilateral, 103 00:05:41,680 --> 00:05:44,440 Speaker 3: not all animals are. There are lots of sea creatures 104 00:05:44,520 --> 00:05:50,039 Speaker 3: like sponges, jellyfish, hydri and corals, that are animals but 105 00:05:50,120 --> 00:05:55,440 Speaker 3: are not Bilatarians. We don't know for sure when exactly 106 00:05:55,480 --> 00:05:58,680 Speaker 3: this split took place, when the last common ancestor of 107 00:05:58,760 --> 00:06:02,600 Speaker 3: all bilatarians split off from the ancestors of other animals, 108 00:06:02,600 --> 00:06:04,960 Speaker 3: but based on what I've been reading, I think it's 109 00:06:05,040 --> 00:06:08,560 Speaker 3: probably sometime between roughly five hundred and fifty and six 110 00:06:08,680 --> 00:06:11,880 Speaker 3: hundred million years ago. Is clearly it pre dates the 111 00:06:12,400 --> 00:06:16,920 Speaker 3: Cambrian Explosion, because in the Cambrian era, starting around five 112 00:06:17,000 --> 00:06:20,679 Speaker 3: hundred and fifty million years ago, you see a great 113 00:06:20,839 --> 00:06:26,039 Speaker 3: diffusion or profusion of different animal body plans that exhibit 114 00:06:26,080 --> 00:06:30,400 Speaker 3: bilateral symmetry. So clearly their last common ancestor was before that. 115 00:06:31,240 --> 00:06:34,760 Speaker 3: There's still debate about exactly what that animal was like, 116 00:06:35,000 --> 00:06:39,480 Speaker 3: but whatever its exact features were, it is mind boggling 117 00:06:39,520 --> 00:06:47,600 Speaker 3: to imagine the common ancestor of all of the world's fish, crabs, cats, squid, slugs, 118 00:06:47,920 --> 00:06:50,719 Speaker 3: barnacles and worms all in one body. 119 00:06:51,160 --> 00:06:53,120 Speaker 2: Yeah, you can't just combine all those things in your 120 00:06:53,160 --> 00:06:54,960 Speaker 2: head and say, like, all right, a little bit of 121 00:06:54,520 --> 00:06:56,839 Speaker 2: the cat, a little bit of the squid. It's a 122 00:06:56,920 --> 00:06:58,679 Speaker 2: different sort of arithmetic in play. 123 00:06:59,320 --> 00:07:02,320 Speaker 3: But one of the things, apart from bilateral symmetry that 124 00:07:02,480 --> 00:07:08,280 Speaker 3: makes Bilatarians unique is their degree of cephalization. That they 125 00:07:08,480 --> 00:07:12,200 Speaker 3: these animals really started to develop heads in ways that 126 00:07:12,320 --> 00:07:16,520 Speaker 3: non biletarian animals did not. And the authors of a 127 00:07:16,520 --> 00:07:19,920 Speaker 3: paper I was looking at, they they define cephalization as 128 00:07:20,040 --> 00:07:25,080 Speaker 3: quote anterior concentration, and remember anterior means front, so front 129 00:07:25,120 --> 00:07:30,640 Speaker 3: facing concentration of nervous tissue, sensory organs, and the appearance 130 00:07:30,680 --> 00:07:35,960 Speaker 3: of dedicated feeding structures surrounding the mouth. Now, one question 131 00:07:36,040 --> 00:07:38,800 Speaker 3: I was wondering about was how to even decide which 132 00:07:39,000 --> 00:07:42,760 Speaker 3: is the anterior part of an animal that doesn't already 133 00:07:42,840 --> 00:07:45,520 Speaker 3: have a head. I think the answer is it's where 134 00:07:45,560 --> 00:07:49,240 Speaker 3: the mouth is. Makes sense. Yeah, Now to get some 135 00:07:49,280 --> 00:07:53,920 Speaker 3: more perspective on why and how a head developed in Bilatarians, 136 00:07:54,080 --> 00:07:57,400 Speaker 3: I was reading a few chapters from a book. It 137 00:07:57,560 --> 00:08:00,960 Speaker 3: was a book called Creatures of acxis The Rise of 138 00:08:01,000 --> 00:08:03,920 Speaker 3: the Animal Kingdom, published by Hill and Wang two thousand 139 00:08:03,920 --> 00:08:07,440 Speaker 3: and seven by an author named Wallace Arthur. 140 00:08:07,880 --> 00:08:07,960 Speaker 2: So. 141 00:08:08,040 --> 00:08:11,080 Speaker 3: The author of this book, Wallace Arthur is an evolutionary 142 00:08:11,120 --> 00:08:14,440 Speaker 3: biologist who was a professor at the University of Galway 143 00:08:14,520 --> 00:08:17,080 Speaker 3: in Ireland. I looked him up and it seems like 144 00:08:17,120 --> 00:08:19,720 Speaker 3: his work focused a lot on the interplay between evolution 145 00:08:19,840 --> 00:08:23,360 Speaker 3: and development and the emergence of animal body plans, which 146 00:08:23,360 --> 00:08:25,800 Speaker 3: is what we're talking about here, And in a couple 147 00:08:25,880 --> 00:08:29,000 Speaker 3: of chapters of this book he has a very nice, 148 00:08:29,000 --> 00:08:33,720 Speaker 3: plain language summary of the likely pressures leading early by 149 00:08:33,800 --> 00:08:38,959 Speaker 3: leetarians to acquire ahead. So one interesting thing to think 150 00:08:38,960 --> 00:08:42,680 Speaker 3: about here is that the early evolution of the animal 151 00:08:42,679 --> 00:08:47,160 Speaker 3: lineage found different types of symmetries. So the first animals 152 00:08:47,200 --> 00:08:50,400 Speaker 3: were not symmetrical, and there are animals today that are 153 00:08:50,440 --> 00:08:54,080 Speaker 3: not symmetrical in their bodies, like sponges. You know, you 154 00:08:54,160 --> 00:08:56,640 Speaker 3: can't cut them down the middle and get a mirror 155 00:08:56,679 --> 00:09:01,559 Speaker 3: image in any direction. Then there came animals with radial symmetry, 156 00:09:02,040 --> 00:09:06,240 Speaker 3: where the body is symmetrically reproduced around an axis in 157 00:09:06,280 --> 00:09:09,880 Speaker 3: the middle. And a great example here would be a jellyfish. Jellyfish, 158 00:09:10,280 --> 00:09:14,400 Speaker 3: they're not bilaterally symmetrical, but they're radially symmetrical. Finally, there 159 00:09:14,400 --> 00:09:18,000 Speaker 3: came animals with bilateral symmetry, tracing back to a common 160 00:09:18,040 --> 00:09:21,760 Speaker 3: ancestor that is known in the literature as the ur bileatarian, 161 00:09:22,000 --> 00:09:26,040 Speaker 3: so biletarian with the letters you are in front of it, 162 00:09:26,080 --> 00:09:29,320 Speaker 3: you are meaning like original or first. And again we 163 00:09:29,360 --> 00:09:31,640 Speaker 3: don't know exactly what this animal was like, but Arthur 164 00:09:31,720 --> 00:09:34,560 Speaker 3: thinks the best guess is that it was somewhat similar 165 00:09:34,960 --> 00:09:39,560 Speaker 3: to modern flatworms. This, he acknowledges this is debatable, and 166 00:09:39,600 --> 00:09:41,440 Speaker 3: I was reading a bit about the modern debate here 167 00:09:41,480 --> 00:09:45,079 Speaker 3: it seems like this is still one of the one 168 00:09:45,160 --> 00:09:47,560 Speaker 3: of the possible pictures of what this creature was like. 169 00:09:48,240 --> 00:09:52,000 Speaker 3: So Arthur asks a question, if you compare a bilaterally 170 00:09:52,040 --> 00:09:56,920 Speaker 3: symmetrical flatworm with a radially symmetrical animal like a jellyfish, 171 00:09:57,280 --> 00:10:00,640 Speaker 3: can we really say that one is more complex than 172 00:10:00,679 --> 00:10:04,559 Speaker 3: the other? He writes, quote, does a flatworm have more 173 00:10:04,640 --> 00:10:08,960 Speaker 3: different types of parts than a jellyfish? Well, not really. Yes, 174 00:10:09,000 --> 00:10:11,800 Speaker 3: it has left and right sides, which a jellyfish does not, 175 00:10:12,040 --> 00:10:15,440 Speaker 3: but that's about it. Although the flatworm has head and 176 00:10:15,520 --> 00:10:18,720 Speaker 3: tail ends while the jellyfish does not, The jellyfish has 177 00:10:18,720 --> 00:10:21,800 Speaker 3: a top side and an underside, the latter having the mouth, 178 00:10:22,160 --> 00:10:24,800 Speaker 3: which pretty much amount to the same thing. And the 179 00:10:24,880 --> 00:10:29,640 Speaker 3: jellyfish has tentacles while the flatworm does not. And yet 180 00:10:29,640 --> 00:10:32,200 Speaker 3: despite this basic parity, or maybe you might even say 181 00:10:32,200 --> 00:10:35,240 Speaker 3: that the jellyfish seems more complex, we do tend to 182 00:10:35,320 --> 00:10:40,280 Speaker 3: think of bilaterally symmetrical animals as more complex than animals 183 00:10:40,280 --> 00:10:42,880 Speaker 3: with radial symmetry. Why do we think of them that way. Well, 184 00:10:43,400 --> 00:10:46,160 Speaker 3: Arthur says that there could be a good reason for this, 185 00:10:46,200 --> 00:10:50,800 Speaker 3: and it's that bilateral symmetry led to subsequent steps of 186 00:10:50,880 --> 00:10:56,440 Speaker 3: increasing complexity. Bilateral symmetry was not itself necessarily more complex, 187 00:10:56,840 --> 00:11:01,760 Speaker 3: but it became a platform for future complexity to emerge, 188 00:11:02,160 --> 00:11:05,400 Speaker 3: making the point that some changes in evolution can seem 189 00:11:05,440 --> 00:11:09,360 Speaker 3: really important to us because they are necessary precursors to 190 00:11:09,559 --> 00:11:13,080 Speaker 3: other developments, maybe millions of years down the line, and 191 00:11:13,160 --> 00:11:16,800 Speaker 3: you couldn't always necessarily predict what those future developments would 192 00:11:16,800 --> 00:11:19,480 Speaker 3: be at the time. Like if we were standing there 193 00:11:19,480 --> 00:11:22,760 Speaker 3: in the pre Cambrian era looking at the orbilatarian, you 194 00:11:22,760 --> 00:11:26,000 Speaker 3: wouldn't necessarily be able to look at this little flatworm 195 00:11:26,120 --> 00:11:28,040 Speaker 3: like creature or whatever it was that it looked like 196 00:11:28,040 --> 00:11:31,080 Speaker 3: some kind of little little organism that has left and 197 00:11:31,160 --> 00:11:34,760 Speaker 3: right sides that roughly mirror each other and think, well, yes, 198 00:11:35,240 --> 00:11:37,520 Speaker 3: this is going to be big, This will turn into 199 00:11:37,520 --> 00:11:39,559 Speaker 3: spiders and cats and octopuses. 200 00:11:41,440 --> 00:11:42,160 Speaker 2: But that is. 201 00:11:42,120 --> 00:11:45,520 Speaker 3: Exactly what happened. It became this sort of platform for 202 00:11:45,840 --> 00:11:49,640 Speaker 3: future development. But to come back to the question, what 203 00:11:50,040 --> 00:11:54,400 Speaker 3: is it about these early Bilatarians that favors the evolution 204 00:11:54,559 --> 00:11:57,920 Speaker 3: of a head. Well, Arthur argues that it is the 205 00:11:57,960 --> 00:12:02,800 Speaker 3: peculiarities of pre cam animal movement. It had to do 206 00:12:02,840 --> 00:12:07,439 Speaker 3: with how animals move. So he says, you know, jellyfish, 207 00:12:07,480 --> 00:12:11,800 Speaker 3: this animal with radial symmetry swims around in the open sea. 208 00:12:11,920 --> 00:12:13,880 Speaker 3: You know, it floats in the water column. It kind 209 00:12:13,880 --> 00:12:16,280 Speaker 3: of pulses to swim where it wants. And then you 210 00:12:16,360 --> 00:12:18,760 Speaker 3: might have other animals that have radial symmetry, like the 211 00:12:18,800 --> 00:12:22,320 Speaker 3: sea anemone. This lives it's a sessile organism, so it 212 00:12:22,360 --> 00:12:24,600 Speaker 3: lives most of its life by sticking itself to a 213 00:12:24,640 --> 00:12:30,360 Speaker 3: surface and staying there, you know, grabbing things from the water. Flatworms, however, 214 00:12:31,160 --> 00:12:36,120 Speaker 3: creep across the two dimensional surfaces of solid objects like 215 00:12:36,280 --> 00:12:39,800 Speaker 3: rocks in the water. So you can imagine what he 216 00:12:39,880 --> 00:12:43,920 Speaker 3: thinks is likely the form of the orbiletarian traversing the 217 00:12:43,920 --> 00:12:47,920 Speaker 3: face of a flat boulder in an archaic lagoon. And 218 00:12:47,960 --> 00:12:50,680 Speaker 3: so he zeros in on the different ways that these 219 00:12:50,720 --> 00:12:54,840 Speaker 3: creatures move. For the jellyfish with radial symmetry floating in 220 00:12:54,880 --> 00:12:57,880 Speaker 3: the water, Arthur says, there is little reason to think 221 00:12:57,920 --> 00:13:01,320 Speaker 3: of any direction as forward or backward. All directions are 222 00:13:01,360 --> 00:13:05,240 Speaker 3: basically the same. The sessile sea an enemy doesn't generally 223 00:13:05,280 --> 00:13:07,719 Speaker 3: travel around, so travel isn't a big issue for it. 224 00:13:07,800 --> 00:13:11,960 Speaker 3: But for the flatworm like or biltarian, there is a 225 00:13:12,200 --> 00:13:17,080 Speaker 3: very definite forward and backward regime in the way that 226 00:13:17,120 --> 00:13:19,600 Speaker 3: this animal moves. You can think of the difference between 227 00:13:19,920 --> 00:13:23,439 Speaker 3: a car and an aerial drone. You know, the jellyfish 228 00:13:23,480 --> 00:13:25,400 Speaker 3: might be more like the aerial drone. It can kind 229 00:13:25,400 --> 00:13:28,280 Speaker 3: of go in whatever direction a car has to like 230 00:13:28,480 --> 00:13:32,679 Speaker 3: aim its movement. It crawls, it creeps along on a 231 00:13:32,720 --> 00:13:33,680 Speaker 3: forward path. 232 00:13:34,080 --> 00:13:36,320 Speaker 2: That's a good way of putting it. Yeah, yeah, drones 233 00:13:37,000 --> 00:13:37,760 Speaker 2: versus cars. 234 00:13:37,840 --> 00:13:41,600 Speaker 3: Yeah, now, no, there's absolutely nothing wrong with moving like 235 00:13:41,640 --> 00:13:44,560 Speaker 3: a drone, you know, the jellyfish, and there's nothing wrong 236 00:13:44,600 --> 00:13:48,480 Speaker 3: with these other lineages. Jellyfish can be highly successful without 237 00:13:48,480 --> 00:13:51,720 Speaker 3: a brain and with limited range of behaviors. They're doing 238 00:13:51,800 --> 00:13:54,080 Speaker 3: just find how they are, and this leads to what 239 00:13:54,240 --> 00:13:57,840 Speaker 3: Arthur calls an evolutionary cul de sac. You know, they're 240 00:13:57,960 --> 00:14:00,880 Speaker 3: just successful in the way they already are. But for 241 00:14:00,920 --> 00:14:06,200 Speaker 3: the orbiletarian, with a definite bias for forward movement, there 242 00:14:06,360 --> 00:14:09,480 Speaker 3: is a lot of reason to differentiate the front of 243 00:14:09,520 --> 00:14:12,080 Speaker 3: the body from the back. There are reasons this animal 244 00:14:12,160 --> 00:14:15,920 Speaker 3: needs to change based on the way it moves. Arthur writes, quote, 245 00:14:16,280 --> 00:14:18,679 Speaker 3: it is more important to be able to detect the 246 00:14:18,720 --> 00:14:21,640 Speaker 3: features of the area you are moving into than the 247 00:14:21,640 --> 00:14:24,880 Speaker 3: one you're leaving behind. So it is to be expected 248 00:14:24,920 --> 00:14:28,440 Speaker 3: that natural selection will favor variants that have more of 249 00:14:28,480 --> 00:14:32,400 Speaker 3: their nerve net upfront. As part of this concentration of 250 00:14:32,440 --> 00:14:35,480 Speaker 3: perceptive powers at the front of the animal, in the 251 00:14:35,520 --> 00:14:38,360 Speaker 3: region that will one day merit the term head, there 252 00:14:38,360 --> 00:14:43,160 Speaker 3: may be rudimentary forward pointing outgrowths densely populated with sensory 253 00:14:43,240 --> 00:14:48,040 Speaker 3: nerves primitive antennae. And I was thinking about this. Maybe 254 00:14:48,040 --> 00:14:50,040 Speaker 3: this is getting a little too philosophical about it, but 255 00:14:50,160 --> 00:14:53,160 Speaker 3: you could argue that the evolution of the head in 256 00:14:53,240 --> 00:14:57,160 Speaker 3: animals is related to the nature of time. For an 257 00:14:57,280 --> 00:15:01,360 Speaker 3: organism that specializes in moving in one direction, moving like 258 00:15:01,400 --> 00:15:05,360 Speaker 3: a car, or like a flatworm moving forward along varied terrain, 259 00:15:06,040 --> 00:15:08,680 Speaker 3: the gathering of nerve cells and sensory organs in the 260 00:15:08,720 --> 00:15:12,840 Speaker 3: front reflects the fact of reality that it is more 261 00:15:12,880 --> 00:15:16,000 Speaker 3: important to sense and react to the future where you 262 00:15:16,080 --> 00:15:18,800 Speaker 3: are headed than to the past where you've just been. 263 00:15:19,240 --> 00:15:22,280 Speaker 3: The past can't hurt you anymore, but the future can no. 264 00:15:22,400 --> 00:15:24,240 Speaker 2: I think that's a good way of looking at it. 265 00:15:24,080 --> 00:15:27,360 Speaker 2: And it reminds me of some accounts. Off the top 266 00:15:27,400 --> 00:15:29,800 Speaker 2: of my head. I can't recall how accurate these are 267 00:15:29,800 --> 00:15:32,200 Speaker 2: held up to be, but there was at least an 268 00:15:32,200 --> 00:15:37,120 Speaker 2: idea that was put forward in Western writing that certain 269 00:15:37,240 --> 00:15:42,680 Speaker 2: members of Native Arctic groups kind of referred linguistically to 270 00:15:44,040 --> 00:15:49,440 Speaker 2: something in the distance as being tomorrow, like this relationship 271 00:15:49,520 --> 00:15:53,880 Speaker 2: between where you will be and how you think about 272 00:15:54,000 --> 00:15:57,360 Speaker 2: what is ahead of you. And yeah, I can sort 273 00:15:57,360 --> 00:15:59,480 Speaker 2: of see that reflected in what we're talking about here. 274 00:16:00,040 --> 00:16:02,640 Speaker 3: Oh, this came up when we were talking about the 275 00:16:02,720 --> 00:16:07,480 Speaker 3: cultural spatialization of time. Yeah, how people represent time in 276 00:16:07,640 --> 00:16:10,280 Speaker 3: as a type of physical space or the metaphor of 277 00:16:10,320 --> 00:16:13,120 Speaker 3: the space around them. And I don't remember if that 278 00:16:13,320 --> 00:16:16,120 Speaker 3: example in particular was thought to be valid, but that 279 00:16:16,160 --> 00:16:19,720 Speaker 3: there are cultural differences in the spatial metaphors people used 280 00:16:19,800 --> 00:16:22,880 Speaker 3: to describe, like the future in the past and so forth. 281 00:16:23,520 --> 00:16:27,120 Speaker 2: Yeah, yeah, but even today, you know, we can easily 282 00:16:27,280 --> 00:16:31,640 Speaker 2: think about everything that's coming into us is like our future. 283 00:16:32,000 --> 00:16:34,400 Speaker 2: You know, it's the future of our body in that 284 00:16:34,640 --> 00:16:36,880 Speaker 2: in what we are consuming the you know, the future 285 00:16:36,920 --> 00:16:40,000 Speaker 2: of our thoughts based on the sense data that's entering 286 00:16:40,480 --> 00:16:44,440 Speaker 2: entering our body and our mind and so forth. So 287 00:16:44,920 --> 00:16:47,120 Speaker 2: uh yeah, I can see this this holding up. Whereas 288 00:16:47,200 --> 00:16:50,160 Speaker 2: what is it like? I mean, to the limited extent 289 00:16:50,200 --> 00:16:52,160 Speaker 2: you can even ask this question, what is it like then? 290 00:16:52,520 --> 00:16:56,000 Speaker 2: For the creature that is not farward loaded, that is, 291 00:16:56,080 --> 00:16:58,040 Speaker 2: you know, it's kind of like an a nowness. It's 292 00:16:58,120 --> 00:17:02,320 Speaker 2: kind of perhaps something at least distantly comparable to that 293 00:17:02,960 --> 00:17:07,520 Speaker 2: state of calmness and serenity that we aspire to, you know, 294 00:17:08,040 --> 00:17:09,679 Speaker 2: or so many of us aspire to to try and 295 00:17:09,720 --> 00:17:14,840 Speaker 2: get out of that forward headlong you know, sprint into 296 00:17:14,880 --> 00:17:15,880 Speaker 2: the future. 297 00:17:15,760 --> 00:17:29,200 Speaker 3: Assume the mind of a jellyfish. Yeah yeah, okay. Next 298 00:17:29,320 --> 00:17:34,240 Speaker 3: ecological consideration pressure on the creation of a head in 299 00:17:34,600 --> 00:17:39,760 Speaker 3: the early piletarians. Arthur says that forward movement also favors 300 00:17:39,800 --> 00:17:42,879 Speaker 3: the evolution of a front facing mouth. If you think 301 00:17:42,920 --> 00:17:45,440 Speaker 3: about this, this will make sense. It's kind of obvious. 302 00:17:45,560 --> 00:17:48,840 Speaker 3: Like if you feed by taking things into an orifice 303 00:17:48,840 --> 00:17:51,919 Speaker 3: in your body, it's best to be able to aim 304 00:17:52,040 --> 00:17:56,480 Speaker 3: your body movement to engulf food matter with that orifice. 305 00:17:56,880 --> 00:17:59,239 Speaker 3: So like, in the same way that it wouldn't make 306 00:17:59,280 --> 00:18:02,320 Speaker 3: sense to build a combine harvester with its intake on 307 00:18:02,400 --> 00:18:05,359 Speaker 3: the side. Right, you'd want it in the front of 308 00:18:05,400 --> 00:18:07,640 Speaker 3: the vehicle so you can aim it at the thing 309 00:18:07,680 --> 00:18:09,200 Speaker 3: you're trying to harvest. 310 00:18:09,520 --> 00:18:13,760 Speaker 2: Essentially an eat the future approach. Basically we've covered so. 311 00:18:13,800 --> 00:18:18,080 Speaker 3: Far right, So aiming the mouth orifice at food and 312 00:18:18,160 --> 00:18:22,960 Speaker 3: making sure food gets inside also requires extra motor control 313 00:18:23,359 --> 00:18:26,920 Speaker 3: around this region of the body. And this also favors 314 00:18:27,240 --> 00:18:31,000 Speaker 3: nerve cells being concentrated at the anterior or the front 315 00:18:31,160 --> 00:18:34,200 Speaker 3: of the bileatarian body. So nerve cells want to gather 316 00:18:34,280 --> 00:18:37,240 Speaker 3: there not just to sense what is ahead in your 317 00:18:37,320 --> 00:18:41,400 Speaker 3: movement schema, but also to control the mouth to eat 318 00:18:41,480 --> 00:18:44,560 Speaker 3: what is ahead in the movement schema. And you can 319 00:18:44,600 --> 00:18:47,840 Speaker 3: see this, this direct connection between nerve cell density and 320 00:18:47,880 --> 00:18:52,240 Speaker 3: eating behavior in an example that Arthur sites, which are 321 00:18:52,680 --> 00:18:56,400 Speaker 3: modern snails and slugs, some of the simpler bileateian animals 322 00:18:56,440 --> 00:19:00,680 Speaker 3: extant today. These creatures, he writes quote, have a arrangement 323 00:19:00,760 --> 00:19:03,920 Speaker 3: of mouth and nerve cells such that the nerves form 324 00:19:04,000 --> 00:19:07,600 Speaker 3: a ring around the mouth or the esophagus, and at 325 00:19:07,680 --> 00:19:11,320 Speaker 3: various points around this ring are expanded groupings of nerve 326 00:19:11,400 --> 00:19:15,879 Speaker 3: cells called ganglia or mini brains if you like. So 327 00:19:16,040 --> 00:19:19,520 Speaker 3: I love that. Of course, what begins as ganglia for 328 00:19:19,640 --> 00:19:22,159 Speaker 3: control of just like a mouth, you know, the eating 329 00:19:22,240 --> 00:19:26,520 Speaker 3: orifice could well evolve over millions of years into denser 330 00:19:26,560 --> 00:19:30,200 Speaker 3: and more complex structures of neurons, and eventually could even 331 00:19:30,280 --> 00:19:34,639 Speaker 3: become a brain. And so I thought this was fascinating. 332 00:19:34,680 --> 00:19:38,600 Speaker 3: According to Arthur's argument here, so much of the strange 333 00:19:38,640 --> 00:19:43,959 Speaker 3: and complicated and unpredictable evolutionary potential of the bileatarian body 334 00:19:44,000 --> 00:19:48,040 Speaker 3: plan arises out of the simple circumstance that these animals, 335 00:19:48,080 --> 00:19:52,439 Speaker 3: the Orbileatarians, had specific limitations on their range of movement, 336 00:19:52,760 --> 00:19:56,800 Speaker 3: that their world was a world of moving forward. One 337 00:19:56,800 --> 00:19:58,760 Speaker 3: more thing from this book I wanted to mention before 338 00:19:58,760 --> 00:20:01,800 Speaker 3: I move on is something that he talks about in 339 00:20:01,840 --> 00:20:04,600 Speaker 3: the next chapter, which is sort of the idea that 340 00:20:04,720 --> 00:20:09,040 Speaker 3: cephalization is not a binary It's not like you are 341 00:20:09,119 --> 00:20:13,520 Speaker 3: cephalized or not, but a question of degree. Some creatures 342 00:20:13,560 --> 00:20:17,919 Speaker 3: are strongly cephalized, others are more weakly cephalized. And to 343 00:20:17,960 --> 00:20:21,000 Speaker 3: illustrate this, Arthur begins by telling a story about a 344 00:20:21,000 --> 00:20:23,800 Speaker 3: time he was collecting centipedes from an area along the 345 00:20:23,840 --> 00:20:27,400 Speaker 3: coast of northeast England. He says he collected a number 346 00:20:27,400 --> 00:20:29,800 Speaker 3: of centipedes. He brought him back to the lab for examination, 347 00:20:30,280 --> 00:20:32,880 Speaker 3: where they seem to be functioning fine. Some of them 348 00:20:32,920 --> 00:20:35,920 Speaker 3: had injuries, like they might be missing legs or parts 349 00:20:35,920 --> 00:20:39,600 Speaker 3: of legs, but he explains that these centipedes have an 350 00:20:39,640 --> 00:20:43,840 Speaker 3: adaptation where they cover the stumps of their missing appendages 351 00:20:44,240 --> 00:20:47,840 Speaker 3: with a thick black substance that looks like tar, presumably 352 00:20:47,920 --> 00:20:51,840 Speaker 3: to seal off the wound and prevent anything that's on 353 00:20:51,880 --> 00:20:54,280 Speaker 3: the outside from getting in or anything on the inside 354 00:20:54,280 --> 00:20:55,000 Speaker 3: from getting out. 355 00:20:55,520 --> 00:20:57,760 Speaker 2: Seems like a solid approach, some sort of weird black 356 00:20:57,800 --> 00:20:59,120 Speaker 2: centipede sealant. 357 00:20:58,840 --> 00:21:01,960 Speaker 3: Okay, yep, yeap, seal it up. But then he came 358 00:21:02,000 --> 00:21:05,919 Speaker 3: across something weird, he writes, quote to my surprise, I 359 00:21:06,000 --> 00:21:10,040 Speaker 3: found that one specimen had lost its head and had 360 00:21:10,160 --> 00:21:14,840 Speaker 3: used that same black tar technique to seal the wound. Strangely, 361 00:21:15,119 --> 00:21:18,159 Speaker 3: it was moving around in a normal fashion, just like 362 00:21:18,200 --> 00:21:21,159 Speaker 3: all its friends who had retained their heads. It walked 363 00:21:21,160 --> 00:21:24,040 Speaker 3: in the way centipedes do, usually in a forward direction, 364 00:21:24,400 --> 00:21:28,240 Speaker 3: but it was also able to retreat backward from threatening stimulis, 365 00:21:28,320 --> 00:21:30,960 Speaker 3: such as my giving it a tap on its anterior 366 00:21:31,160 --> 00:21:33,800 Speaker 3: end with a pair of tweezers. Not only did it 367 00:21:33,840 --> 00:21:36,880 Speaker 3: do so for a considerable period in the lab hours, 368 00:21:37,320 --> 00:21:39,639 Speaker 3: but it had probably done so for an even longer 369 00:21:39,680 --> 00:21:43,480 Speaker 3: one days in the wild before I found it, because 370 00:21:43,680 --> 00:21:47,800 Speaker 3: the wound looked old. Inasmuch as you can tell these things. Wow, 371 00:21:48,400 --> 00:21:52,080 Speaker 3: So he says that this headless centipede eventually died because 372 00:21:52,119 --> 00:21:55,560 Speaker 3: it probably starved to death. No mouth means it can't eat. 373 00:21:56,320 --> 00:22:00,439 Speaker 3: But that's amazing. It's hard for us, being extremely highly 374 00:22:00,440 --> 00:22:04,480 Speaker 3: cephalized organisms, to imagine that, Like the first problem to 375 00:22:04,520 --> 00:22:07,199 Speaker 3: reach the crisis point with a headless animal would be 376 00:22:07,240 --> 00:22:10,040 Speaker 3: that it starves to death. And the difference here is 377 00:22:10,119 --> 00:22:13,399 Speaker 3: the level of cephalization in each organism. The centipede and 378 00:22:13,440 --> 00:22:17,159 Speaker 3: the human are both cephalized. They both have heads, but 379 00:22:17,240 --> 00:22:21,280 Speaker 3: the human is strongly cephalized and the centipede only weakly so. 380 00:22:21,320 --> 00:22:25,600 Speaker 3: In humans, control of the body functions is strongly localized 381 00:22:25,600 --> 00:22:27,760 Speaker 3: in the brain, which is in the head, and the 382 00:22:27,800 --> 00:22:31,480 Speaker 3: body really can't do anything without the brain. Centipedes, on 383 00:22:31,520 --> 00:22:33,960 Speaker 3: the other hand, they do have a brain of sorts 384 00:22:34,000 --> 00:22:36,199 Speaker 3: in the head. There is a cluster of nervous tissue 385 00:22:36,240 --> 00:22:39,160 Speaker 3: up there, but they also have clusters of nerve cells 386 00:22:39,160 --> 00:22:42,479 Speaker 3: in each body segment that work as a distributed system 387 00:22:42,520 --> 00:22:46,320 Speaker 3: of many secondary brains throughout the body. Even without the 388 00:22:46,320 --> 00:22:48,679 Speaker 3: brain in the head, the body segments can keep on 389 00:22:48,800 --> 00:22:52,400 Speaker 3: living and acting individually. They can make the centipede walk around, 390 00:22:52,520 --> 00:22:56,080 Speaker 3: react to stimuli, and so forth, but not forever. But 391 00:22:56,359 --> 00:22:59,200 Speaker 3: to come back to headlessness in nature, I want to 392 00:22:59,240 --> 00:23:05,080 Speaker 3: emphasize again that not every animal naturally has a head. Jellyfish, 393 00:23:05,160 --> 00:23:10,240 Speaker 3: for example, there's some disagreement to the extent to which 394 00:23:10,280 --> 00:23:13,240 Speaker 3: you should say they are cephalized, but they really don't 395 00:23:13,240 --> 00:23:16,240 Speaker 3: have anything you would normally call ahead. In fact, jellyfish, 396 00:23:16,240 --> 00:23:19,680 Speaker 3: you don't even have brains or hearts, or even blood 397 00:23:19,760 --> 00:23:22,480 Speaker 3: for that matter. They do have a nervous system, but 398 00:23:22,640 --> 00:23:26,120 Speaker 3: it is distributed throughout the body tissues without a central 399 00:23:26,200 --> 00:23:29,680 Speaker 3: like a major command center like a biletarian brain. 400 00:23:30,359 --> 00:23:34,560 Speaker 2: Yeah, it's fascinating and maybe a little treacherous right to 401 00:23:34,960 --> 00:23:37,280 Speaker 2: look at some of these organisms and ask questions like, 402 00:23:37,280 --> 00:23:40,040 Speaker 2: all right, where's the head? Where's the head at? Because 403 00:23:40,160 --> 00:23:44,639 Speaker 2: sometimes an animal that seems to be headless may just 404 00:23:44,680 --> 00:23:47,800 Speaker 2: be all head It's another way of sort of spinning it. 405 00:23:48,560 --> 00:23:51,160 Speaker 2: This was an argument I was reading about from some 406 00:23:51,200 --> 00:23:55,280 Speaker 2: researchers at Stanford University and UC Berkeley. This came out 407 00:23:55,320 --> 00:23:58,000 Speaker 2: I believed this earlier this month. In a paper published 408 00:23:58,000 --> 00:24:00,960 Speaker 2: in Nature, they found that ceased to once thought of 409 00:24:01,000 --> 00:24:05,440 Speaker 2: as headless, actually exhibit gene expressions associated with head development 410 00:24:05,520 --> 00:24:09,679 Speaker 2: all over their bodies. Meanwhile, genes related to torsos and 411 00:24:09,760 --> 00:24:13,880 Speaker 2: tails were largely absent, so you could, I guess, think 412 00:24:13,920 --> 00:24:18,120 Speaker 2: of them more as disembodied or never bodied heads than 413 00:24:18,160 --> 00:24:20,920 Speaker 2: you would think of them as a body without a head. 414 00:24:21,119 --> 00:24:25,000 Speaker 3: Another interesting fact about sea stars is that so they're 415 00:24:25,040 --> 00:24:28,560 Speaker 3: thought of as animals with radial symmetry, not bilateral symmetry, 416 00:24:29,000 --> 00:24:33,640 Speaker 3: but they are actually descended from Bileatrians, So these are 417 00:24:33,840 --> 00:24:38,200 Speaker 3: animals whose ancestors are part of that group. They did 418 00:24:38,240 --> 00:24:41,480 Speaker 3: have bilateral symmetry and they evolved to lose it. 419 00:24:43,040 --> 00:24:46,600 Speaker 2: The idea of something having a head in a body 420 00:24:46,640 --> 00:24:50,159 Speaker 2: and then becoming mostly head I was instantly reminded of 421 00:24:50,200 --> 00:24:54,800 Speaker 2: a character from Marvel comics named Modoc. Included a picture 422 00:24:54,800 --> 00:24:56,920 Speaker 2: for you here, Joe. You're not familiar with this guy, 423 00:24:56,960 --> 00:24:59,399 Speaker 2: but essentially I believe he was supposed to have been 424 00:24:59,400 --> 00:25:01,800 Speaker 2: a human at one point in the comics, and I 425 00:25:01,800 --> 00:25:06,719 Speaker 2: think definitely in the movies, and he has, through you know, 426 00:25:07,000 --> 00:25:11,439 Speaker 2: comic book events, become just this enormous head with much 427 00:25:11,440 --> 00:25:14,320 Speaker 2: smaller arms and legs hanging off of him. You know, 428 00:25:14,359 --> 00:25:16,600 Speaker 2: there's a sense that like even these may go eventually 429 00:25:16,640 --> 00:25:19,320 Speaker 2: because he doesn't need them. It's all you know, cerebral 430 00:25:19,359 --> 00:25:20,040 Speaker 2: power in there. 431 00:25:20,640 --> 00:25:23,760 Speaker 3: I notice a strange body feature here, which is that 432 00:25:23,840 --> 00:25:29,000 Speaker 3: Modoc's legs are not on the underside of his head body, 433 00:25:29,000 --> 00:25:31,760 Speaker 3: but the front of his head body, almost like little 434 00:25:31,840 --> 00:25:35,040 Speaker 3: tentacles or fe feeder jaws around the mouth. 435 00:25:35,760 --> 00:25:40,880 Speaker 2: Yeah. Yeah, and this being, I guess, the first imagined 436 00:25:41,440 --> 00:25:44,240 Speaker 2: being that we've referenced here. It's something to keep in 437 00:25:44,320 --> 00:25:46,600 Speaker 2: mind with all of these is the question of like, okay, well, 438 00:25:46,640 --> 00:25:50,399 Speaker 2: what was literally intended with this character, but also like 439 00:25:50,720 --> 00:25:56,160 Speaker 2: how did the imaginations behind them? How did the creators 440 00:25:56,200 --> 00:25:59,200 Speaker 2: behind them sort of channel some of these ideas we've 441 00:25:59,240 --> 00:26:02,959 Speaker 2: already been discussed, either overtly or just sort of subconsciously, 442 00:26:03,080 --> 00:26:05,280 Speaker 2: Like what do we think of when we have a head, 443 00:26:05,680 --> 00:26:08,480 Speaker 2: what do we think of them when we imagine beings 444 00:26:08,800 --> 00:26:11,760 Speaker 2: that have lost their head, that have a much larger 445 00:26:11,800 --> 00:26:14,159 Speaker 2: head than a body, and so forth. Like there's a 446 00:26:14,200 --> 00:26:16,879 Speaker 2: lot of you know, overt and then sort of hidden 447 00:26:16,960 --> 00:26:17,760 Speaker 2: language in there. 448 00:26:17,800 --> 00:26:20,520 Speaker 3: I think, yes, in some ways, it's kind of hard 449 00:26:20,600 --> 00:26:24,840 Speaker 3: not to approach everything with a sort of vertebrate anatomical bias, 450 00:26:24,880 --> 00:26:29,000 Speaker 3: where you, you know, you are looking for the analogies 451 00:26:29,080 --> 00:26:32,200 Speaker 3: to the way your body is put together in everything 452 00:26:32,240 --> 00:26:34,360 Speaker 3: in the world, even in even in you know, non 453 00:26:34,440 --> 00:26:37,520 Speaker 3: living inanimate objects. I mean you often, Rob, I'm sure 454 00:26:37,520 --> 00:26:39,359 Speaker 3: you have this experience. You look at some kind of 455 00:26:39,400 --> 00:26:42,200 Speaker 3: inanimate object and look for the head or the legs 456 00:26:42,600 --> 00:26:43,160 Speaker 3: or whatever. 457 00:26:44,160 --> 00:26:46,760 Speaker 2: Yeah. Yeah, And and on top of that, like the 458 00:26:46,800 --> 00:26:51,000 Speaker 2: other wrinkle for a human's especially is that in the 459 00:26:51,000 --> 00:26:53,760 Speaker 2: head we see a centralization of the nervous system on 460 00:26:53,840 --> 00:26:56,400 Speaker 2: the front and upper part of the creature amid its 461 00:26:56,400 --> 00:26:59,960 Speaker 2: sense organs in its mouth. It's the defining feature of 462 00:27:00,040 --> 00:27:02,920 Speaker 2: both humans and when humans are looking at animals, and 463 00:27:03,000 --> 00:27:06,480 Speaker 2: certainly animals, it's you know, it's become it's come to 464 00:27:06,480 --> 00:27:08,880 Speaker 2: be thought of as a center of personhood and self. 465 00:27:09,280 --> 00:27:12,200 Speaker 2: It is the face, you know, at the front part 466 00:27:12,200 --> 00:27:15,880 Speaker 2: of the head, if you will. And of course that 467 00:27:15,880 --> 00:27:19,040 Speaker 2: that factors into a lot of our conceptions of not 468 00:27:19,080 --> 00:27:22,760 Speaker 2: only people, animals, but also just inanimate things. We're always 469 00:27:22,760 --> 00:27:25,679 Speaker 2: looking for the face. We're looking for that that front 470 00:27:25,720 --> 00:27:32,080 Speaker 2: facing communication array of micro and macro expressions, you know, 471 00:27:32,720 --> 00:27:36,359 Speaker 2: and we can also couple that with this idea of 472 00:27:36,640 --> 00:27:40,879 Speaker 2: the head the face looking into the future, and what 473 00:27:41,000 --> 00:27:46,600 Speaker 2: happens when these two future gazing facial arrays see each other. Then, Oh, 474 00:27:46,640 --> 00:27:49,320 Speaker 2: you have to have all the computation. What does it 475 00:27:49,400 --> 00:27:52,560 Speaker 2: mean that this person is in my immediate future? Am 476 00:27:52,640 --> 00:27:55,720 Speaker 2: I going to eat them? Are we going to communicate 477 00:27:55,720 --> 00:27:57,760 Speaker 2: on seven level? Or are we going to turn our 478 00:27:57,800 --> 00:28:01,000 Speaker 2: eyes away and continue on our own forward core? Yeah? 479 00:28:01,040 --> 00:28:03,600 Speaker 3: I mean, for a second there, I was thinking about 480 00:28:04,040 --> 00:28:07,919 Speaker 3: the salients of faces. Why we notice faces everywhere? I mean, 481 00:28:07,920 --> 00:28:10,320 Speaker 3: we see faces in electrical outlets, and we see the 482 00:28:10,400 --> 00:28:14,080 Speaker 3: you know, the boxing octopus and the kadhook on the wall. 483 00:28:14,119 --> 00:28:17,080 Speaker 3: Everything is a face. Part of me wanted to interpret 484 00:28:17,080 --> 00:28:19,639 Speaker 3: that as a result of our highly social brains. You know, 485 00:28:19,680 --> 00:28:22,359 Speaker 3: we're always looking at other people's faces to try to 486 00:28:22,520 --> 00:28:25,040 Speaker 3: understand what they're thinking, how they're feeling towards us, and 487 00:28:25,080 --> 00:28:28,120 Speaker 3: all that. That is very important. But then it could 488 00:28:28,160 --> 00:28:31,520 Speaker 3: actually be even deeper than that in an ecological origin, 489 00:28:31,600 --> 00:28:36,040 Speaker 3: because of course, understanding like looking for the face of 490 00:28:36,080 --> 00:28:38,920 Speaker 3: a predatory animal could help you understand like, am I 491 00:28:39,240 --> 00:28:43,240 Speaker 3: in the attentional zone of this this big looking animal 492 00:28:43,280 --> 00:28:47,000 Speaker 3: over there? So it could go even deeper than social factors. 493 00:28:47,840 --> 00:28:49,680 Speaker 2: Yeah, no, that's a good point, and it goes back 494 00:28:49,720 --> 00:28:52,960 Speaker 2: to numerous things we've discussed, but most recently talking about 495 00:28:52,960 --> 00:28:55,200 Speaker 2: what happens when you meet eyes with just a household cat. 496 00:28:55,600 --> 00:28:59,480 Speaker 2: Yeah know, and how that is maybe an anxious experience 497 00:28:59,480 --> 00:29:01,440 Speaker 2: for the cat because again, it doesn't have all these 498 00:29:01,520 --> 00:29:04,480 Speaker 2: layers of human cognition. It gets down to the basic 499 00:29:05,440 --> 00:29:08,760 Speaker 2: interactions that a creature like a house cat that is 500 00:29:08,760 --> 00:29:12,200 Speaker 2: both predator and prey would have when it's locking eyes 501 00:29:12,240 --> 00:29:15,560 Speaker 2: with another organism. And so on top of all that, 502 00:29:16,840 --> 00:29:20,680 Speaker 2: as we begin to venture into the world of fantastic beings, 503 00:29:20,720 --> 00:29:26,400 Speaker 2: imagined beings, creatures of mythology, folklore, and much more. Yeah, 504 00:29:26,440 --> 00:29:28,800 Speaker 2: it's like to imagine something without a head is of 505 00:29:28,800 --> 00:29:31,400 Speaker 2: course also to imagine something without a face, And you 506 00:29:31,440 --> 00:29:33,680 Speaker 2: could just you can easily just you could focus on 507 00:29:33,680 --> 00:29:35,960 Speaker 2: the facial aspect of this, and there's plenty of ways 508 00:29:36,000 --> 00:29:38,000 Speaker 2: to cut that apart. But then on top of that 509 00:29:38,080 --> 00:29:40,800 Speaker 2: this idea of here is a thing that has no 510 00:29:40,960 --> 00:29:45,040 Speaker 2: head or separated from its head, and knowing like what 511 00:29:45,040 --> 00:29:46,960 Speaker 2: that would mean for a human being, Like you said, 512 00:29:47,800 --> 00:29:52,240 Speaker 2: survival is not possible even for a very short period 513 00:29:52,280 --> 00:29:55,440 Speaker 2: of time. I mean there, of course, studies and there've 514 00:29:55,480 --> 00:29:58,560 Speaker 2: long been some fascination about to what degree a human 515 00:29:58,560 --> 00:30:02,440 Speaker 2: head can survive without its body. The answer still remains 516 00:30:03,000 --> 00:30:06,800 Speaker 2: not very long at all. So to take all of that, 517 00:30:06,960 --> 00:30:11,000 Speaker 2: these observations and knowledge about the importance of a human head, 518 00:30:11,040 --> 00:30:14,040 Speaker 2: the role that a head plays in a human's life 519 00:30:14,200 --> 00:30:17,320 Speaker 2: and personhood, what happens when that is cut away? What 520 00:30:17,400 --> 00:30:19,560 Speaker 2: happens when you have an imagine being that can live 521 00:30:19,640 --> 00:30:22,920 Speaker 2: without a head? And what does it mean? You know? 522 00:30:22,960 --> 00:30:26,719 Speaker 3: When I go back in my history of taking in 523 00:30:26,960 --> 00:30:29,640 Speaker 3: stories of headless beings, the main one that comes to mind, 524 00:30:29,720 --> 00:30:31,920 Speaker 3: of course, is probably not a big surprise, is the 525 00:30:31,920 --> 00:30:35,440 Speaker 3: headless Horseman story and Ichabod Crane and all that, which 526 00:30:35,480 --> 00:30:39,360 Speaker 3: has been realized in many you know, Halloween specials on 527 00:30:39,400 --> 00:30:42,080 Speaker 3: TV and stuff like that through all the years. And 528 00:30:42,280 --> 00:30:44,880 Speaker 3: one thing I always remember thinking about the headless horsemen 529 00:30:44,880 --> 00:30:46,600 Speaker 3: that made them different than other kind of ghosts and 530 00:30:46,640 --> 00:30:51,000 Speaker 3: monsters is that the headless horseman seemed less like a 531 00:30:51,240 --> 00:30:55,520 Speaker 3: personal entity and more like a machine or a robot 532 00:30:56,200 --> 00:30:59,640 Speaker 3: than most other types of monsters and ghosts. Do you 533 00:30:59,640 --> 00:31:00,760 Speaker 3: have this experience? 534 00:31:01,360 --> 00:31:03,280 Speaker 2: Yeah, yeah, And I think it's one of the reasons 535 00:31:03,320 --> 00:31:05,680 Speaker 2: that at times, I mean, there's also the effects level 536 00:31:05,720 --> 00:31:07,880 Speaker 2: of this, but it's one of one of the reasons 537 00:31:07,880 --> 00:31:11,160 Speaker 2: that at times filmmakers have struggled with portraying it. I 538 00:31:11,160 --> 00:31:13,880 Speaker 2: think of the Tim Burton film where you had Christopher 539 00:31:13,880 --> 00:31:16,320 Speaker 2: Walken playing the headless being, and sometimes you see his head, 540 00:31:16,400 --> 00:31:20,440 Speaker 2: you see his face, because that helps convey like the 541 00:31:20,480 --> 00:31:23,400 Speaker 2: intent and the horror of the thing. You take that away, 542 00:31:23,440 --> 00:31:25,760 Speaker 2: it's like, yeah, it's like a robot. It's like all action, 543 00:31:25,880 --> 00:31:30,280 Speaker 2: but without cognition, all like physical It's certainly still a 544 00:31:30,280 --> 00:31:35,520 Speaker 2: physical threat, but there is no mind communication. Will like, 545 00:31:35,560 --> 00:31:39,120 Speaker 2: you take this entire aspect of what it is to 546 00:31:39,200 --> 00:31:42,920 Speaker 2: be an entity in the physical world, and you remove 547 00:31:43,000 --> 00:31:46,080 Speaker 2: this huge slice of it. How do you reason with that? 548 00:31:46,200 --> 00:31:47,840 Speaker 2: How do you even comprehend it? 549 00:31:48,280 --> 00:31:50,120 Speaker 3: I guess part of it is that even with a 550 00:31:50,160 --> 00:31:54,720 Speaker 3: regular ghost, you know, this imagined entity that doesn't behave 551 00:31:54,800 --> 00:31:58,880 Speaker 3: by normal biological rules, we still make biological inferences about it. 552 00:31:58,920 --> 00:32:01,760 Speaker 3: So like with a ghost, a monster, you can tell 553 00:32:01,800 --> 00:32:04,440 Speaker 3: you're in danger if it looks at you. You know, 554 00:32:04,600 --> 00:32:08,000 Speaker 3: like you are still tracking its gaze to understand what 555 00:32:08,120 --> 00:32:10,360 Speaker 3: its state of mind and attention is doing. And with 556 00:32:10,400 --> 00:32:12,320 Speaker 3: a headless beast. You can't do that. 557 00:32:12,960 --> 00:32:25,040 Speaker 2: Yeah, So we're going to begin to go through some 558 00:32:25,160 --> 00:32:28,080 Speaker 2: various ideas that, you know, especially with with what we've 559 00:32:28,080 --> 00:32:29,640 Speaker 2: talked about so far, I think this will make for 560 00:32:29,640 --> 00:32:34,600 Speaker 2: a nice discussion. The various examples of beings and entities 561 00:32:34,680 --> 00:32:38,320 Speaker 2: that have lost their heads are separated from their heads 562 00:32:38,960 --> 00:32:41,720 Speaker 2: and so forth, and in doing so they often have 563 00:32:41,800 --> 00:32:44,600 Speaker 2: lost a face, though, as we'll discuss, sometimes the face 564 00:32:44,680 --> 00:32:49,920 Speaker 2: finds a way. But let's start with roughly with the 565 00:32:49,960 --> 00:32:53,360 Speaker 2: realm of the divine headless. And I suppose the notion 566 00:32:53,400 --> 00:32:55,560 Speaker 2: of the divine headless is interesting to think of in 567 00:32:55,640 --> 00:32:59,040 Speaker 2: light of some of the popular modern religious views that 568 00:32:59,080 --> 00:33:03,800 Speaker 2: position a mon theistic God as being essentially bodyless. And 569 00:33:03,880 --> 00:33:07,160 Speaker 2: in this respect you might well argue that, well God 570 00:33:07,240 --> 00:33:09,760 Speaker 2: is headless, then if God has no body, then God 571 00:33:09,800 --> 00:33:12,520 Speaker 2: has no head, at least in the literal sense. But 572 00:33:12,600 --> 00:33:14,680 Speaker 2: of course it's hard to escape the head in virtually 573 00:33:14,720 --> 00:33:19,400 Speaker 2: any sort of anthropomorphism or any number of linguistic uses 574 00:33:19,400 --> 00:33:22,280 Speaker 2: of the word head. We even have the term godhead 575 00:33:22,640 --> 00:33:25,800 Speaker 2: used to sum up different theological concepts, particularly in the 576 00:33:26,960 --> 00:33:30,640 Speaker 2: Abrahamic and religions, and also in Hinduism, though. 577 00:33:30,560 --> 00:33:33,920 Speaker 3: That is a false cognate. You know. The head in 578 00:33:34,040 --> 00:33:37,520 Speaker 3: godhead actually has nothing to do with the biological head. 579 00:33:37,640 --> 00:33:40,920 Speaker 3: I think it is derived from the term that essentially 580 00:33:40,960 --> 00:33:44,880 Speaker 3: means like godhood. It is like the essence of godness. 581 00:33:45,200 --> 00:33:48,400 Speaker 2: Yeah, but then you throw that into a language system 582 00:33:48,440 --> 00:33:50,800 Speaker 2: where head means head. You can't help but think of 583 00:33:50,840 --> 00:33:54,520 Speaker 2: it as such. Right now. Another thing to look at is, Okay, 584 00:33:54,560 --> 00:33:57,000 Speaker 2: if your god or goddess of choice goes through different 585 00:33:57,000 --> 00:34:01,560 Speaker 2: avatars or incarnations, then well, no matter what their pure 586 00:34:01,720 --> 00:34:03,840 Speaker 2: form is, they're going to wind up having a head 587 00:34:03,960 --> 00:34:07,960 Speaker 2: of some sort at some point, at least for a while. 588 00:34:09,200 --> 00:34:12,480 Speaker 2: I think a fantasy example we might turn to if 589 00:34:12,520 --> 00:34:15,600 Speaker 2: you think of a Sauron from The Lord of the Rings, right, 590 00:34:15,719 --> 00:34:18,760 Speaker 2: he takes on a number of bipedal and headed being 591 00:34:19,160 --> 00:34:22,239 Speaker 2: of forms, but ultimately assumes the physical form of a 592 00:34:22,239 --> 00:34:25,360 Speaker 2: great disembodied eye, devoid of body and head in the 593 00:34:25,400 --> 00:34:26,440 Speaker 2: literal sense. 594 00:34:26,560 --> 00:34:28,799 Speaker 3: Though it is interesting that it's still the eyes at 595 00:34:28,800 --> 00:34:31,120 Speaker 3: the top of a tower, making it kind of like 596 00:34:31,200 --> 00:34:31,600 Speaker 3: a head. 597 00:34:32,320 --> 00:34:35,320 Speaker 2: Yeah. Yeah, And I guess the idea is that during 598 00:34:35,360 --> 00:34:39,440 Speaker 2: that incarnation, like it has, he has become all seeking 599 00:34:39,600 --> 00:34:42,600 Speaker 2: all because there is only one thing that it wants. 600 00:34:42,640 --> 00:34:46,040 Speaker 2: It is not consumption. It is just to find the 601 00:34:46,120 --> 00:34:46,640 Speaker 2: one ring. 602 00:34:47,200 --> 00:34:49,560 Speaker 3: It's kind of the opposite of the headless horseman issue, 603 00:34:49,600 --> 00:34:52,560 Speaker 3: where like you can't tell where it's looking, all Sauron 604 00:34:52,880 --> 00:34:54,520 Speaker 3: is is looking at something. 605 00:34:55,000 --> 00:34:59,680 Speaker 2: Yeah. Now, in actual religions, though, gods do sometimes lose 606 00:34:59,680 --> 00:35:03,360 Speaker 2: their head heads, but unlike with human beings, this doesn't 607 00:35:03,400 --> 00:35:05,520 Speaker 2: spell the end of it, because here you're dealing with 608 00:35:06,520 --> 00:35:11,160 Speaker 2: again divine beings and magical powers and so forth. We've 609 00:35:11,200 --> 00:35:15,160 Speaker 2: discussed in the past. The Hindu god Rahu, this is 610 00:35:15,200 --> 00:35:19,560 Speaker 2: the entity that is associated with eclipses. He was once 611 00:35:19,600 --> 00:35:22,640 Speaker 2: a proud oserer, a demi god of immense power and 612 00:35:22,760 --> 00:35:27,760 Speaker 2: hunger seeking immortality. For demi gods are just another realm 613 00:35:27,800 --> 00:35:31,560 Speaker 2: in the wheel of Samsara. Rahu drinks the divine nectar 614 00:35:31,719 --> 00:35:35,680 Speaker 2: known as Amrita, but before he can swallow it all 615 00:35:35,680 --> 00:35:38,840 Speaker 2: the way, as it's passing down his throat, all powerful 616 00:35:38,920 --> 00:35:42,040 Speaker 2: Vishnu decapitates him for the transgression. 617 00:35:42,480 --> 00:35:44,000 Speaker 3: He wasn't supposed to drink the nectar. 618 00:35:44,040 --> 00:35:46,000 Speaker 2: He was not supposed to drink it and was stopped 619 00:35:46,000 --> 00:35:48,360 Speaker 2: in the act of drinking it. So the power of 620 00:35:48,400 --> 00:35:51,239 Speaker 2: the nectar. In at least some tellings and understandings of 621 00:35:51,280 --> 00:35:55,879 Speaker 2: the story makes his disembodied head immortal, and so this 622 00:35:56,000 --> 00:35:59,440 Speaker 2: cleaved and fallen god continually seeks his revenge on the 623 00:35:59,440 --> 00:36:03,480 Speaker 2: two planets jerry deities who ratted him out to Vishnu. However, 624 00:36:04,080 --> 00:36:06,359 Speaker 2: in a lot of these tellings, his headless body is 625 00:36:06,400 --> 00:36:09,160 Speaker 2: still in the mix under the new name of Ketu, 626 00:36:09,560 --> 00:36:13,319 Speaker 2: so both Rahu and Katu take on the classification of 627 00:36:13,440 --> 00:36:17,880 Speaker 2: shadow planets in Indian astronomy. Katu is indeed sometimes depicted 628 00:36:17,960 --> 00:36:22,920 Speaker 2: in Hindu iconography as a body without a head. Interesting now, 629 00:36:23,000 --> 00:36:26,719 Speaker 2: Hinduism also boasts a headless goddess of sorts by the 630 00:36:26,840 --> 00:36:32,400 Speaker 2: name of Chinnamasta. She is depicted as a nude, red fleshed, 631 00:36:32,640 --> 00:36:37,520 Speaker 2: self decapitating tantric goddess. She's generally depicted standing atop the 632 00:36:37,560 --> 00:36:40,640 Speaker 2: bodies of a divine couple with a scimitar in one 633 00:36:40,680 --> 00:36:43,640 Speaker 2: hand and her own head in the other, with three 634 00:36:43,760 --> 00:36:47,680 Speaker 2: jets of blood spurting out of her neck, which her 635 00:36:47,680 --> 00:36:51,680 Speaker 2: own severed head plus two attendants like gaze upward and 636 00:36:51,680 --> 00:36:53,880 Speaker 2: open their mouths and drink like a fountain. 637 00:36:54,280 --> 00:36:57,359 Speaker 3: So she's understood to have cut her own head off 638 00:36:57,440 --> 00:36:59,200 Speaker 3: with the scimitar. 639 00:36:59,400 --> 00:37:02,520 Speaker 2: Right right, now I suppose she is still head in 640 00:37:02,640 --> 00:37:05,839 Speaker 2: body as one, even in separation, or at least that's 641 00:37:05,840 --> 00:37:10,560 Speaker 2: my understanding. This might differ, you know, if one were 642 00:37:10,600 --> 00:37:15,680 Speaker 2: to dive more into the theology of this particular god 643 00:37:16,200 --> 00:37:21,800 Speaker 2: and what these depictions mean. But it's my limited understanding 644 00:37:21,800 --> 00:37:25,080 Speaker 2: that you still think of them as as the same goddess, 645 00:37:25,480 --> 00:37:29,480 Speaker 2: and she's associated with destruction and creation, but also apparently paradoxes, 646 00:37:30,239 --> 00:37:34,320 Speaker 2: which I think is worth highlighting. Now, another headless divine 647 00:37:34,320 --> 00:37:37,920 Speaker 2: figure can be found in Chinese mythology, and this is 648 00:37:38,000 --> 00:37:43,360 Speaker 2: Sing Ten. As Anne Beryl describes in Chinese Mythology and introduction, 649 00:37:44,360 --> 00:37:48,680 Speaker 2: Sing Ten is a failed hero in minor deity. His 650 00:37:48,760 --> 00:37:52,040 Speaker 2: plight is described in the Shanghaijing, the Classic of Mountains 651 00:37:52,040 --> 00:37:53,880 Speaker 2: and Seas, which we've talked about on the show before. 652 00:37:53,920 --> 00:37:56,160 Speaker 2: This is a work from between five hundred and two 653 00:37:56,200 --> 00:38:01,359 Speaker 2: hundred BCE. Taking into account of variations of his name, 654 00:38:02,320 --> 00:38:05,799 Speaker 2: Beryl writes that we might very roughly translate his name 655 00:38:05,880 --> 00:38:10,480 Speaker 2: as punished by heavens or formed by heavens or And 656 00:38:10,520 --> 00:38:12,319 Speaker 2: I love this one because this one sounds like he 657 00:38:12,320 --> 00:38:16,800 Speaker 2: could straight up be a death metal band. Is form 658 00:38:17,040 --> 00:38:20,600 Speaker 2: prematurely dying? Who you can just imagine that in that 659 00:38:20,680 --> 00:38:24,160 Speaker 2: nearly illegible script on a festival poster. 660 00:38:24,040 --> 00:38:26,360 Speaker 3: Right right, yes, in the Batlord fond. 661 00:38:26,840 --> 00:38:30,760 Speaker 2: Yeah. So Beryl points out that the story of Sing 662 00:38:30,760 --> 00:38:34,160 Speaker 2: Ten kind of stands out for its gruesomeness in the 663 00:38:34,280 --> 00:38:38,120 Speaker 2: in the classic, and this is partially thought to be 664 00:38:38,120 --> 00:38:41,399 Speaker 2: because many instances of sex and violence were like edited 665 00:38:41,440 --> 00:38:43,440 Speaker 2: a bit and cleaned up a bit over time in 666 00:38:43,480 --> 00:38:46,120 Speaker 2: that work, and for one reason or another, this one 667 00:38:46,160 --> 00:38:51,319 Speaker 2: was not. She describes Sington as an odentic warrior, and 668 00:38:51,360 --> 00:38:52,880 Speaker 2: we might well think of him as kind of a 669 00:38:52,880 --> 00:38:55,360 Speaker 2: Satanic figure as well, if you know, comparing him to 670 00:38:55,760 --> 00:39:02,400 Speaker 2: modern Christian and certainly Western literature depictions of Satan, because 671 00:39:02,520 --> 00:39:05,200 Speaker 2: we know, for what little we know about him is 672 00:39:05,239 --> 00:39:07,880 Speaker 2: that he winds up in this position of having no 673 00:39:08,000 --> 00:39:11,440 Speaker 2: head due to his hubris, due to his violent opposition 674 00:39:11,719 --> 00:39:15,000 Speaker 2: to the supreme god Huangdi, the Yellow Emperor. 675 00:39:16,320 --> 00:39:17,719 Speaker 3: So what's the story, all right? 676 00:39:17,760 --> 00:39:20,240 Speaker 2: So the story goes that sing Ten, who sometimes described 677 00:39:20,239 --> 00:39:23,400 Speaker 2: as a giant as well, challenges the Yellow Emperor on 678 00:39:23,480 --> 00:39:27,560 Speaker 2: a particular battleground for a divine rule. You know, He's like, 679 00:39:27,760 --> 00:39:32,319 Speaker 2: you shouldn't be ruined everything, I should. Let's battle it. Out. Now, 680 00:39:32,480 --> 00:39:35,759 Speaker 2: the Yellow Emperor is victorious in the end, and he 681 00:39:35,840 --> 00:39:40,000 Speaker 2: beheads his challenger and buries the head on cheng Yang Mountain. 682 00:39:41,160 --> 00:39:45,440 Speaker 2: But Sing Ten is too proud to die. According to 683 00:39:45,480 --> 00:39:49,120 Speaker 2: one translation, quote Ten made his nipples serve as eyes 684 00:39:49,239 --> 00:39:52,720 Speaker 2: and his navel as his mouth, and brandishing his shield 685 00:39:52,800 --> 00:39:56,280 Speaker 2: and battle axe, he danced. And we might well imagine 686 00:39:56,280 --> 00:40:00,840 Speaker 2: this dance is a proud kind of war dance, a 687 00:40:00,840 --> 00:40:04,520 Speaker 2: a vein dance, a spiteful dance. Again, he has been defeated, 688 00:40:04,560 --> 00:40:07,640 Speaker 2: his head has been removed from his giant body, and 689 00:40:07,719 --> 00:40:12,319 Speaker 2: yet he refuses to truly give up, to cease his 690 00:40:12,360 --> 00:40:16,319 Speaker 2: opposition to the Yellow Wimperor, and continues to fight, though 691 00:40:16,360 --> 00:40:19,200 Speaker 2: in time the body dies as well and the body 692 00:40:19,280 --> 00:40:22,319 Speaker 2: is buried as well. Now I included some illustrations of 693 00:40:22,360 --> 00:40:25,040 Speaker 2: this entity for you to look at here Joe, the 694 00:40:25,080 --> 00:40:28,160 Speaker 2: first of which is an older illustration from the Shanghaijiing 695 00:40:28,239 --> 00:40:31,719 Speaker 2: which folks can can look up. Is found in a 696 00:40:31,719 --> 00:40:34,200 Speaker 2: lot of places, very very simple and kind of comical. 697 00:40:34,680 --> 00:40:40,680 Speaker 2: But by doing image searches, especially using the Chinese characters 698 00:40:41,080 --> 00:40:43,680 Speaker 2: for the entity, you can find a number of really 699 00:40:43,760 --> 00:40:46,880 Speaker 2: cool like modern illustrations. I don't know to what extent, 700 00:40:46,920 --> 00:40:51,279 Speaker 2: Like he's been utilized in Chinese comic books and video 701 00:40:51,360 --> 00:40:53,640 Speaker 2: games and whatnot. But it looks like a lot of 702 00:40:53,680 --> 00:40:56,719 Speaker 2: folks have done some very unique sketches of him that 703 00:40:56,880 --> 00:41:00,720 Speaker 2: look very horrifying, very demonic, with like the belly erupting 704 00:41:00,760 --> 00:41:05,200 Speaker 2: into a big fanged mouth and indeed the nipples becoming eyes, 705 00:41:05,760 --> 00:41:08,279 Speaker 2: and you know, this is the ferocious form, you know, 706 00:41:08,360 --> 00:41:11,040 Speaker 2: still carrying and brandishing its battle axe. 707 00:41:12,160 --> 00:41:14,520 Speaker 3: At least one of these illustrations has a little bit 708 00:41:14,560 --> 00:41:15,520 Speaker 3: of Critter's energy. 709 00:41:16,160 --> 00:41:19,719 Speaker 2: Yeah, yeah, they have. Maybe there there's one thing to 710 00:41:19,760 --> 00:41:21,919 Speaker 2: keep in mind, like ideas of like what happens when 711 00:41:22,440 --> 00:41:25,400 Speaker 2: like the head is fused with the body, or thought 712 00:41:25,440 --> 00:41:27,000 Speaker 2: to have fused with the body. We'll get back to 713 00:41:27,080 --> 00:41:29,560 Speaker 2: that in a bit. But yeah, it's like there's also 714 00:41:29,600 --> 00:41:32,040 Speaker 2: this kind of spirit of, well, you can't be head 715 00:41:32,120 --> 00:41:34,640 Speaker 2: me again, Like my head is literally my torso. Now 716 00:41:34,640 --> 00:41:36,160 Speaker 2: what are you going to do? Cut my torso off? 717 00:41:36,440 --> 00:41:38,480 Speaker 3: I can't believe I didn't connect it to this earlier, 718 00:41:38,520 --> 00:41:40,400 Speaker 3: but I mean when you were talking about Modoc, I 719 00:41:40,440 --> 00:41:43,479 Speaker 3: mean the critters, the crits really sort of are all head. 720 00:41:43,480 --> 00:41:47,520 Speaker 3: They're like a head, an eating head with legs and arms. 721 00:41:47,719 --> 00:41:51,439 Speaker 2: Yeah, and what does it mean sort of conceptionally if 722 00:41:51,480 --> 00:41:54,160 Speaker 2: we are imagining a creature that doesn't have a head 723 00:41:54,239 --> 00:41:56,600 Speaker 2: with a mouth, but its body is the mouth, where 724 00:41:56,640 --> 00:42:00,160 Speaker 2: like head and body are fused into one. You know, 725 00:42:00,239 --> 00:42:03,360 Speaker 2: on some level, does that kind of mess with our 726 00:42:03,480 --> 00:42:06,000 Speaker 2: concepts of head and body? Like one of the concepts 727 00:42:06,000 --> 00:42:09,840 Speaker 2: we've discussed in the past is how arguably modern humans 728 00:42:09,840 --> 00:42:14,320 Speaker 2: tend to think of body and head as horse and rider. 729 00:42:14,560 --> 00:42:16,719 Speaker 2: You know, we're the head and there's the body. It's 730 00:42:16,719 --> 00:42:19,560 Speaker 2: doing its thing. But of course there's really more of 731 00:42:19,600 --> 00:42:23,120 Speaker 2: a centaur concept where horse and rider are one, and 732 00:42:23,800 --> 00:42:26,880 Speaker 2: that breaks down in a number of different ways. But 733 00:42:26,920 --> 00:42:29,680 Speaker 2: then what if we imagine, like the horse, human is 734 00:42:29,760 --> 00:42:32,280 Speaker 2: just one entity, you know, Like, how are we supposed 735 00:42:32,320 --> 00:42:35,360 Speaker 2: to take take account of that? Like, here is this creature, 736 00:42:35,480 --> 00:42:40,480 Speaker 2: like the critter like sington, who now has its belly 737 00:42:41,080 --> 00:42:43,200 Speaker 2: more or less in its body, its eyes or in 738 00:42:43,239 --> 00:42:46,279 Speaker 2: its body. What does that mean about its volition and 739 00:42:46,320 --> 00:42:46,840 Speaker 2: its intent? 740 00:42:47,400 --> 00:42:48,840 Speaker 3: I don't have a good answer on this, but I 741 00:42:48,880 --> 00:42:50,600 Speaker 3: was just trying to think, how would your vision be 742 00:42:50,680 --> 00:42:55,600 Speaker 3: different if your eyes were in your nipples'd be farther 743 00:42:55,680 --> 00:42:58,360 Speaker 3: apart than human eyes usually are. And I don't know 744 00:42:58,400 --> 00:42:59,880 Speaker 3: exactly how that would change things. 745 00:43:00,320 --> 00:43:03,480 Speaker 2: Well, yeah, they would be wider apart, and certainly these 746 00:43:03,520 --> 00:43:06,840 Speaker 2: depictions of like Singing ten. You know, he seems to 747 00:43:06,840 --> 00:43:10,080 Speaker 2: be have a very broad giant's body, so the nipples 748 00:43:10,120 --> 00:43:14,720 Speaker 2: are pretty far apart. Yeah, I'm not sure exactly how 749 00:43:14,760 --> 00:43:17,279 Speaker 2: to cut that. But in a way, it's like by 750 00:43:17,320 --> 00:43:20,640 Speaker 2: having the belly be the mouth, it's like it does 751 00:43:20,840 --> 00:43:24,840 Speaker 2: tend to give us this idea that like the hunger 752 00:43:24,920 --> 00:43:27,600 Speaker 2: is even more all consuming, like the belly itself is 753 00:43:27,680 --> 00:43:29,279 Speaker 2: opening up and wishes to eat. 754 00:43:29,719 --> 00:43:32,400 Speaker 3: There will not be like an esophagus in between the 755 00:43:32,440 --> 00:43:35,440 Speaker 3: food and the stomach. You're just like chomping. It's like 756 00:43:35,480 --> 00:43:37,160 Speaker 3: the stomach itself has teeth. 757 00:43:37,640 --> 00:43:39,640 Speaker 2: Yeah, yeah, I don't imagine there's a lot of tasting. 758 00:43:40,920 --> 00:43:42,759 Speaker 2: This critter is not going for the tasting menu, is 759 00:43:42,800 --> 00:43:45,520 Speaker 2: going for the buffet. That's right by the way. If 760 00:43:45,560 --> 00:43:47,759 Speaker 2: we dip back into Hindu epics for just a second, 761 00:43:47,800 --> 00:43:51,080 Speaker 2: there is a demon with these basic features that pops 762 00:43:51,160 --> 00:43:55,600 Speaker 2: up there, known as Kabanda, and the story goes that 763 00:43:55,680 --> 00:44:00,600 Speaker 2: Indra stove this individual's head and thighs in stove them 764 00:44:00,640 --> 00:44:04,120 Speaker 2: into his body with the celestial thunderbolt weapon known as 765 00:44:04,160 --> 00:44:08,759 Speaker 2: the Vadra. But then Indra shows mercy and says, well, 766 00:44:08,800 --> 00:44:11,759 Speaker 2: he's still alive, he should be allowed to eat. So 767 00:44:11,840 --> 00:44:15,359 Speaker 2: Indra gives him long arms and a belly mouth. And 768 00:44:15,440 --> 00:44:19,200 Speaker 2: I included one depiction of this creature here for you, Joe. 769 00:44:19,200 --> 00:44:21,000 Speaker 3: On this drawing. He's kind of cute. He's like a 770 00:44:21,040 --> 00:44:21,879 Speaker 3: blue Teddy bear. 771 00:44:22,560 --> 00:44:25,400 Speaker 2: Yeah. Yeah. But this one's interesting too because it's like 772 00:44:25,440 --> 00:44:28,160 Speaker 2: the head is not removed. The head is just kind 773 00:44:28,160 --> 00:44:31,400 Speaker 2: of like apparently it's like driven down into the body 774 00:44:31,440 --> 00:44:34,640 Speaker 2: with something like it's easy to imagine like some gruesome 775 00:44:35,080 --> 00:44:40,879 Speaker 2: Mortal Kombat esque battle field fatality here, and then that 776 00:44:41,520 --> 00:44:46,600 Speaker 2: is rectified by divine magic to some extent. Now, if 777 00:44:46,600 --> 00:44:51,000 Speaker 2: we look to the world of Japanese jokai, there is 778 00:44:51,040 --> 00:44:54,000 Speaker 2: also a creature there that is described as headless but 779 00:44:54,080 --> 00:44:56,880 Speaker 2: with nipple eyes and a belly mouth. This is a 780 00:44:57,440 --> 00:45:01,880 Speaker 2: donatsura or torso face, according to I couldn't find out 781 00:45:01,920 --> 00:45:04,160 Speaker 2: a lot about this one. I was looking at yokai 782 00:45:04,200 --> 00:45:08,640 Speaker 2: dot com where Matthew Meyer describes this entity and says 783 00:45:08,640 --> 00:45:12,040 Speaker 2: that the main connotation here is to shame and some 784 00:45:12,080 --> 00:45:15,239 Speaker 2: sort of saying in Japanese about lowering the lowering of 785 00:45:15,280 --> 00:45:18,640 Speaker 2: one's face. I think the effectiveness of this is likely. 786 00:45:18,760 --> 00:45:23,040 Speaker 2: You know, something that's lost in translation. M okay. There's 787 00:45:23,120 --> 00:45:29,239 Speaker 2: another yokai that Meyer describes called Kuba kajiri, and this 788 00:45:29,280 --> 00:45:32,640 Speaker 2: one is also apparently sometimes described as headless. It's a 789 00:45:32,719 --> 00:45:35,240 Speaker 2: kind of ghoul that consumes the heads of the dead, 790 00:45:35,880 --> 00:45:39,120 Speaker 2: though plenty of illustrations depict it as having a head, 791 00:45:39,760 --> 00:45:42,440 Speaker 2: as being a being with a head that is gnawing 792 00:45:42,560 --> 00:45:47,560 Speaker 2: on disembodied heads, and this may seem this seems to 793 00:45:47,560 --> 00:45:50,319 Speaker 2: be maybe connected to the idea of bodies buried without 794 00:45:50,360 --> 00:45:53,600 Speaker 2: heads coming back as vengeful spirits that seek out corpse 795 00:45:53,640 --> 00:45:56,400 Speaker 2: heads to eat. It could also be linked to starvation, 796 00:45:56,640 --> 00:45:59,920 Speaker 2: according to Meyer. But at this point, obviously we're our 797 00:46:00,160 --> 00:46:02,800 Speaker 2: beginning to talk about things that are maybe less divine 798 00:46:02,840 --> 00:46:05,800 Speaker 2: and maybe a little more diabolical, a little lower down 799 00:46:05,880 --> 00:46:10,360 Speaker 2: the ladder of power when it comes to supernatural entities. 800 00:46:10,840 --> 00:46:13,839 Speaker 2: And so this is where we're going to leave off. 801 00:46:13,840 --> 00:46:15,480 Speaker 2: But in the next episode we're going to come back 802 00:46:15,520 --> 00:46:17,719 Speaker 2: in and we're going to discuss other examples of more 803 00:46:18,040 --> 00:46:23,600 Speaker 2: outright diabolical headless entities, and we'll also get into the 804 00:46:23,640 --> 00:46:29,160 Speaker 2: works of antiquity and various descriptions of peoples in distant 805 00:46:29,200 --> 00:46:31,680 Speaker 2: parts of the world or distant from the writers and 806 00:46:31,680 --> 00:46:35,360 Speaker 2: observers here, that were said to have no heads, but 807 00:46:35,440 --> 00:46:38,160 Speaker 2: of course to have faces on their bodies. And so 808 00:46:38,239 --> 00:46:41,000 Speaker 2: we'll get into that and discuss like where these ideas 809 00:46:41,040 --> 00:46:44,399 Speaker 2: came from and what they seem to mean. So we'll 810 00:46:44,400 --> 00:46:48,360 Speaker 2: get into that on Thursday. In the meantime, we'll remind 811 00:46:48,400 --> 00:46:50,440 Speaker 2: everyone out there that, Yeah, Stuff to Blow Your Mind 812 00:46:50,520 --> 00:46:53,480 Speaker 2: is a science podcast with core episodes on Tuesdays and Thursdays. 813 00:46:53,520 --> 00:46:56,479 Speaker 2: Mondays we do listener mail.
