The first thing we learn from studying our own circuitry is a simple lesson: most of what we do and think and feel is not under our conscious control.

As we develop better technologies for probing the brain, we detect more problems.

The brain runs its show incognito.

If our brains were simple enough to be understood, we wouldn't be smart enough to understand them.

I'm using the afterlife as a backdrop against which to explore the joys and complexities of being human - it turns out that it's a great lens with which to understand what matters to us.

It is the most wondrous thing we have discovered in the universe, and it is us.

Because vision appears so effortless, we are like fish challenged to understand water.
