I was raised as an Orthodox Jew in a major neighborhood specializing in that, in Brooklyn. And somewhere when I was about 14, something changed. And that change probably involved updating every molecule in my body, in that I sort of realized: this is nonsense, there's no God, there's no free will, there is no purpose.

I am completely of the school that mind is entirely the manifestation of brain. So when there's a change in mind, there's got to be a neurobiological underpinning.

I'm a professor of neuroscience at Stanford University, and I'm kind of half-neurobiologist, half-primatologist.
