Why not? I mean, that's what we do.

Is all persuasion self persuasion? You tell me.

(Laughter)

This must be who I'm directly descended from.

Why would God wire you to do something and then not have you do it?

In some, they wear masks. In many, soldiers are anonymous in uniform.

This book deals with anthropology.

They spring from the same source.

This is for science, for human knowledge.

He was seeing this anthropologist, but...

The ones on the right were made by Neanderthals, our distant cousins, not our direct ancestors, living in Europe, and they date from around 50,000 or 60,000 years ago.

He majors in social anthropology.

Except, if you had taken physical anthropology as recently as 20 or 30 years ago, in many cases you would have learned basically that same classification of humanity.

That is not necessary.

They're clicking on things and staring at screens.

Archeology is a science that studies the activities of human beings and their changes through the study of the traces left by them.

(Laughter)

(Laughter)

Because, look, I'm not a social anthropologist but I have a friend who is.

Because neoteny means the retention of immature qualities into adulthood.

But there is a totally different type of learning, which I call expansive learning, and this is the learning you do on behalf of humanity.

To my surprise, the anthropologist was accused of murder.

Destroying our environment has to stop.

We have a way to look at Earth like that, you know,

Historically, for example, chopsticks according to one Japanese anthropologist who wrote a dissertation about it at the University of Michigan resulted in long term changes in the dentition, in the teeth, of the Japanese public.

The next artist is Hazel Clausen.

I applied to read anthropology at university.

This is the Forensic Anthropology Research Facility, and on a six acre plot there are approximately 75 cadavers at any given time that are being studied by forensic anthropologists and researchers who are interested in monitoring a rate of corpse decomposition.

Man should make peaceful use of technologies.

The anthropologist delivered a lecture on primitive cultures.

It's us mammals we're one of these.

The world needs you, badly.

Well there's a couple of ways to do it.

Man has no instincts, from the anthropologist Ashley Montagu

It gets adopted because people use it and it's made for humans.

And you move from a discipline of engineering, you move from a discipline of chemistry, into a discipline of biology.

We don't have that kind of time.

And a few days ago, Matt said

A very stunning conclusion.

I call book learning.

But the materiality matters too, because in every society that anthropologists have looked at, material stuff operates as a kind of language a language of goods, a symbolic language that we use to tell each other stories stories, for example, about how important we are.

Possibilities about our ancestry, but not the probabilities that we're really looking for.

There might be some way of treating that as true.

I think the key idea is that language is a way of negotiating relationships, and human relationships fall into a number of types.

I believe our only hope for the future is to adopt a new conception of human ecology, one in which we start to reconstitute our conception of the richness of human capacity.
