  • So one of the propositions that I?

  • Set forth for you last week was that

  • the most real Things are

  • the things that are most permanent across time and and that

  • Manifests themselves in the largest number of situations and those are the things that you have to map successfully in order to survive

  • survive of individuals that survive as a species over a very long period Of time and so

  • the question is one question is

  • what are the

  • constants of experience if you are a

  • follower of the Evolutionary

  • Psychologists and to some degree the evolutionary biologist, but I would say more the psychologists

  • like to be in close Metis

  • They have a very afro centric

  • view of Human evolution and the idea basically is that

  • After we diverged from the common ancestor between Chimpanzees Bonobos and human beings

  • We spent a tremendous amount of time in the african environment

  • Mostly on the veldt although. We're not absolutely certain about that

  • We're also very good in water human beings and we have some of the features of aquatic mammals

  • so

  • while hairlessness being one of them

  • Women have a subcutaneously

  • They are fat or feeder quite nicely adapted for swimming and so buckminster fuller who I wouldn't call a mainstream

  • evolutionary psychologist

  • Hypothesized back in the 70s that we spent some period of time in our evolutionary history living on beaches near the ocean

  • That idea really

  • Echoes for me because we like beaches a lot, and it's a great place if you want to get easy food

  • And we're pretty damn good at swimming for for Terrestrial mammals

  • And we are hairless

  • And we do cry salt tears and there's a lot of evidence that we and our feet if you think about our feet

  • They're quite flipper like I know we are stand up and all that and walk, so that's part of the adaptation

  • But we're pretty good at swimming

  • so

  • anyways

  • The classical evolutionary psychology view is that we spent most of our time on the African veldt?

  • It in the critical period of our evolutionary development

  • let's say after we diverged from this common ancestor, and that were adapted for that environment and one of the

  • consequences of that is the idea that we're that things have changed so much around us that we're really not adapted to the

  • environment that we're in anymore, and I really believe that because I think that the idea that the

  • primary Forces that shaped our evolution

  • shaped them during that period of time

  • call it A

  • Roughly a seven million period Year period of time something like that and

  • That that was somehow a special time for human evolution that set our nature. I don't believe that

  • I mean, it's true to some degree, but

  • it's more useful to view the evolution of human cognitive processes over the entire span of

  • Evolutionary history and not necessarily give preference to any particular

  • Epoch and I certainly believe that the idea that we're no longer adapted to the environment because of our rapid technological

  • Transformations is simply not true and the reason. I think that it's not true is because the fundamental constants of the

  • Environment let's say or it's more of the fundamental constants constituent elements of being I think that's the right way to think about it

  • They're the same they haven't changed a bit

  • and there is no way of changing them as far as I can tell without us being radically and

  • Incomprehensibly different than we are and you know with with the rapid rise of artificial intelligence and robotics and all of that

  • It's certainly possible then in five hundred years will be completely

  • Will be so like unlike the way we are now that we won't even be the same creatures

  • I don't think that's a particularly great outcome, but it's certainly possible. So what are the fundamental?

  • constituent Elements

  • Well, they're expressed in mythology, but they're not merely symbolic. I think it's the wrong way to think about it

  • They're symbolic, but they reflect a very deep reality and they actually reflect a reality that's not easily apprehensible

  • Directly by the senses now your senses are tuned for a particular duration

  • That's roughly excuse me

  • That's roughly the duration that you live let's say

  • But more importantly it's the duration whatever that duration is across which meaningful actions take place

  • And we kind of have some idea of what that duration is. You know if you look at a

  • computer screen if

  • it has a

  • Refresh rate of less than 60 Hertz you can see it's liquor abut above 60 Hertz you can't its uniform and with movies

  • Anywhere between 20 and 50 frames a second is enough to give you the illusion of continual motion

  • so you know we live in a universe that's

  • Above the tenth of a second domain or maybe the hundredth of a second somewhere in there anyways

  • And I mean it's not like time isn't almost infinitely subdivide

  • At higher levels of resolution than that, but we don't operate

  • generally speaking at higher temporary

  • A something approximating 1/2 a second to a second you know I mean, it's an estimate obviously

  • but a

  • second is a

  • meaningful unit of time for a person and a hundredth of a second really isn't and certainly a billionth of a second isn't and then

  • You know we can think across hours and days and weeks and months

  • But we really can't once you start getting out in two years it gets kind of sketchy and it's hard to think more than five

  • Years down the road and the reason for that is that the particulars upon which you're basing your predictions are likely to change

  • Sufficiently over a five year period So that extending out your vision past that just exposes you to accelerating error

  • Right and that and of course that's the problem with predicting the future period So we live in a time range

  • That's about say a tenth of a second to three three years something like that now

  • I know it can expand Beyond up

  • But that's that's kind of where we're set and our senses seem to be tuned to those durations and and to be

  • Operative so that we make proper

  • Decisions within those durations and and also from from a particular spatial position and so forth you know

  • Your eyes see what's roughly

  • Maybe we could say a walkable distance in front of you something like that, so

  • Then you get detect things and in the locale that enables you to immediately interact with things

  • But it isn't necessarily the case that senses that are tuned to do that are

  • Also tuned to inform you directly about what the most permanent things about being itself are I think that those things have to be?

  • Inferred and there's some there's some supporting evidence for that kind of thing from

  • from pSycholinguistics

  • there's a level of

  • categorization that we seem to

  • Manifest more or less automatically or implicitly so for example when children perceive?

  • Animals they they perceive at the level of cat or dog

  • They don't they don't perceive at the level of subspecies like siamese cat or or?

  • Or or let's say samoyed you know there's this. There's a natural

  • I can't remember what they call that base category something like that

  • it's usually specified by very short words that are easily learn about and so the

  • Linguistic system seems to map right on to the to the object recognition

  • Characteristics of the Sensory systems that are built right into it and and if they weren't built into it

  • We couldn't communicate easily because our natural categories. I think that's it, but it's probably wrong our natural categories

  • They have to be the same for every one or it would be very difficult for us to communicate, okay?

  • So having said all that then the question is

  • Well, what are the most?

  • What are the most real categories?

  • and I think there's there's a real division in ways to think about this because there's a scientific way of thinking about it and

  • And in in that case the most real categories are well

  • mathematical equations certainly seem to be and in the top category there that equations that describe the

  • physical universe, but then then the

  • hypothesis of

  • the existence of such things as protons and and

  • electrons, and you know that the material elements that make up everything that's every element of being the

  • possible exception of empty space

  • But in the in the mythological world the categories, I think are more derived from Darwinian

  • by the effect of Darwinian processes on cognitive and perceptual function

  • So which is to say that we have learned to perceive and then to infer those things that are most necessary?

  • For us in order to continue our existence

  • Propagate live well all of those things and that would be true at the level of individual survival

  • And maybe it's also true at the level of Growth survival although

  • You know the there's a tremendous debate among evolutionary biologists about whether or not selection can take place at the level of the group

  • Anyways there are these basic level categories that manifest themselves to you and then there's categories of the imagination that you have to infer up

  • from the sensory domain and we do that partly in Science by

  • Comparing our sensory representations across people

  • But we also do it by thinking abstractly conceptualizing abstractly

  • And you know one of the things that's interesting about

  • Abstractions is it's not clear whether they're more or less real than the things they're abstracted from you know that this is a perennial debate

  • among let's call them ontology who are

  • interested in that fundamental fundamental nature of reality itself in some sense independent of Conceptual structures are

  • numbers more or less real than the things they represent it's a really hard question to answer because

  • Knowing like using numbers as a representational system gives you unbelievable power

  • And there are mathematicians that believe that there isn't anything more real than mathematical

  • Representations now it depends to some degree of course on how you classify reality. That's the problem with the question like is a

  • Equivalent to be the answer that always is well it depends on how you define a and it depends on how you define b

  • So generally it's not a very useful question, but you can still get the point that there's something very real about abstraction

  • Incredibly real because otherwise why would you bother with them they wouldn't give you any handle on the world?

  • So what's the what's the most useful or what's the most?

  • What's the broadest possible level of abstraction and is there any use of?

  • any utility in thinking in that manner and I tried to

  • make the case last time that that in the

  • Mythological world there are three categories or four depending on what you do with the strange fourth Category?

  • There's a fourth category sort of the category of on categories able

  • entities and

  • So it's sort of the category of everything that not only do you not know but you don't know you don't know it's it's or

  • You can think about it as the category of potential. I actually think that's the best way to think about it

  • Is that it's the dragon of Chaos is the category of potential, and I do believe that

  • Where our materialist view is essentially wrong?

  • I think that the proper way of looking at the at being is that being is?

  • Potential and from that potential whatever consciousness is extracts out the reality that we inhabit anyways

  • that's certainly the mythological Viewpoint and and

  • But it's not just a mythological Viewpoint. It's a it's a

  • sequence of ideas for example that deeply underlies the thinking of young piaget and piaget by the way

  • it was very interested in reconciling the gap between

  • religion and science that's really what he devoted his life to doing and

  • So and there are other streams of philosophy and I would say heidegger the phenomenologist are are

  • Thinking along lines that are similar to this as well because heidegger was concerned not with the nature of material reality

  • but with being as such and and and

  • so

  • You can extract out the viewpoint that I just described from from Mythology, but it isn't the only source of such
