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

You are more likely to believe that a statement is true if you have heard it before - whether or not it is actually true.

We spend our lives on a thin slice between the unimaginably small scales of the atoms that compose us and the infinitely large scales of galaxies.

It is more parsimonious to assume that the sun goes around the Earth, that atoms at the smallest scale operate in accordance with the same rules that objects at larger scales follow, and that we perceive what is really out there. All of these positions were long defended by argument from parsimony, and they were all wrong.

Who you are depends on the sum total of your neurobiology.

If you ever feel lazy or dull, take heart: you're the busiest, brightest thing on the planet.

We are not the ones driving the boat of our behavior, at least not nearly as much as we believe.
