The path up is the path down. The way forward is the way back. The universe inside is outside but the universe outside is inside.

The novels that get praised in the NY Review of Books aren't worth reading. Ninety-seven percent of science fiction is adolescent rubbish, but good science fiction is the best and only literature of our times.

Certitude is seized by some minds, not because there is any philosophical justification for it, but because such minds have an emotional need for certitude.

Taking somebody's money without permission is stealing, unless you work for the IRS; then it's taxation. Killing people en masse is homicidal mania, unless you work for the Army; then it's National Defense. Spying on your neighbors is invasion of privacy, unless you work for the FBI; then it's National Security. Running a whorehouse makes you a pimp and poisoning people makes you a murderer, unless you work for the CIA; then it's counter-intelligence.

I like pacifists and people who have a heavy emotional identification with deathism and war would probably call me a pacifist, but I am a non-invasivist rather than a non-violentist. That is, I believe that an invaded people have the right to defend themselves by any means necessary. This includes putting ground glass or poison in the invaders' food, shooting at them from ambush, sabotage, the general strike, armed revolution, etc. It's up to the invaded to decide which of these techniques they will use. It's not up to some moralist to tell them which techniques are permissible.

Death makes me realize how deeply I have internalized the agnosticism I preach in all my books. I consider dogmatic belief and dogmatic denial very childish forms of conceit in a world of infinitely whirling complexity. None of us can see enough from one corner of space-time to know "all" about the rest of space-time.

What the thinker thinks, the prover proves.
