Hey, it's Guy here. So today's show is all about what makes us, us, ideas from genetic psychology

and philosophy about why we humans are who we are. This episode first aired in July of 2016,

but this time around we've included an amazing new interview. It's with neuroscientist,

Anel Seth, and he says what makes us human is consciousness, our visual and emotional experience

of the world around us and of ourselves in it. But how consciousness even happens and whether

we can recreate it artificially? These are questions that we're still trying to figure out.

You'll hear Anel Seth later on in this really mind-blowing episode, so please take a listen and enjoy.

This is the Ted Radio Hour.

Each week, groundbreaking Ted Talks. Ted. Ted. Technology. Entertainment. Design.

Design. Is that really what's 10 for us? I've never known the...

Delivered at Ted Conferences Around the World. It's the gift of the human imagination.

We've had to believe in impossible things. The true nature of reality beckons from just beyond.

Those talks, those ideas adapted for radio. From NPR.

I'm Guy Ross. So imagine a big, thick book about the size of a dictionary. And inside that book,

each and every page filled with just four letters. Just four letters.

Printed over and over. A, G, C, and T. It's right, four letters of DNA.

The same four letters that every species in the planet has.

It's made up of four letters each representing a chemical compound arranged in just such a way to make you... you.

This is really where the information comes from. It's not the four letters, but exactly how they're connected to each other.

So is it A, G, C, T or A, A, G or A, A, C, T or A, A, A, T?

This, by the way, is Sam Sternberg. I study gene editing technology.

And Sam says, if you print it up all of the A's, G's, and C's, and T's, it takes to complete your entire genetic code.
