If you have certain problems with your brain but are raised in a good home, you might turn out okay. If your brain is fine and your home is terrible, you might still turn out fine. But if you have mild brain damage and end up with a bad home life, you're tossing the dice for a very unlucky synergy.

When we're in a human body, we don't care about universal collapse - instead, we care only about a meeting of the eyes, a glimpse of bare flesh, the caressing tones of a loved voice, joy, love, light, the orientation of a house plant, the shade of a paint stroke, the arrangement of hair.

The brain runs its show incognito.

What we find is that our brains have colossal things happening in them all the time.

It is only through us that God lives. When we abandon him, he dies.

The three-pound organ in your skull - with its pink consistency of Jell-o - is an alien kind of computational material. It is composed of miniaturized, self-configuring parts, and it vastly outstrips anything we've dreamt of building.

We don't really understand most of what's happening in the cosmos. Is there any afterlife? Who knows.
