Transcripts

when did you first become fascinated

with the human brain since forever uh as

far back as I can remember I've been

interested in the human brain I mean uh

I was you know a thoughtful kid

and a bit of an outsider and you you

know sit there thinking about what the

most important things in the world

are uh in your in your little tiny

adolescent

brain and the answer that I came to that

I converged on was uh that all of the

things you can possibly conceive of as

things that are important for human

beings to care about are literally

contained you know in the skull uh both

the perception of them and their

relative values and you know the

solutions to all our problems and all of

our problems are all contained in the

skull and if we knew more about how that

worked

uh how the brain encodes information and

generates desires and generates Agony

and

suffering uh we we could do more about

it you know you think about all the all

the really great triumphs in human

history you think about all the really

horrific

tragedies um you know you think about

the Holocaust you think about um

any prison full of human

stories uh and and all of those

problems boil down to

neurochemistry so if you get a little

bit of control over

that you provide people the option to do

better in the way I read history the way

people have dealt with having better

tools is that they most often in the end

do better uh with huge

asterisks but I think it's a an

interesting a worthy a noble pursuit to

give people more options more tools yeah

that's a fascinating way to look at

human history you just imagine all these

neurobiological mechanisms stal and

Hitler all of these Jenis Khan all of

them just had like a a brain it just a

bunch of neurons you know like few tons

of billions of

neurons uh gaining a bunch of

information over a period of time they

have set a module that does language and

memory and all that and from there in in

in the case of those people they're able

to murder Millions of people yeah and

all that coming

from uh there's not some glorified

notion of a a dictator of this enormous

mind or something like this it's just

it's just the brain yeah yeah I mean a

lot of that has to do with how well

people like that can organize those

around them other brains yeah and so I

always find it interesting to look to

primatology you know look to our closest

non-human relatives uh for Clues as to

how humans are going to behave and and

what particular humans are able to

achieve and so you look

at um chimpanzees and bonobos and you

know they're similar but different in

their social structures

particularly and I went to Emory in

Atlanta and studied under uh France Dall

the great Fran Dall who was kind of the

leading primatologist uh who recently

died and his work in at looking at

chimps through the lens of you know how

you would watch an episode of Friends

and understand the motivations of the

characters interacting with each other

he would look at a chimp colony and

basically apply that lens I'm massively

oversimplifying it if you do that

instead of just saying you know subject

473 you know through his feces at

subject 471

you talk about them in terms of their

human struggles Accord them the Dignity

of themselves as actors with

understandable goals and drives what

they want out of life and primarily it's

you know the things we want out of life

food sex

companionship um

Power uh you can understand chimp and

Boba behavior in those same lights uh

much more EAS easily and I think doing

so gives you the tools you need to

reduce human behavior from the kind of

false complexity that we layer on to it

with

language and look at it in terms of oh

well these humans are looking for

companionship sex food

power um and I think that that's a

pretty powerful tool to have in

understanding human behavior and I just

uh went to the Amazon jungle for a few

weeks and you it's a very visceral

reminder that a lot of life on Earth is

just trying to get laid yeah they're all

screaming at each other like I saw a lot

of monkeys and they're just trying to

impress each other or maybe there's a

battle for power but a lot of the battle

for power has to do with them getting

laid right reading rights often go with

Alpha status and so if you can get a

piece of that then you're going to do

okay and would like to think that we're

somehow fundamentally different but

especially when it talk comes to

primates where really aren you know we

can use fancer poetic language but maybe

some of the underlying drives that

motivate us are um similar yeah I think

that's true and all that is coming from

this the brain
