“Overall, I think that there is at least a good case that absent defeaters, a number of interesting cognitive capacities will explode. I think the most likely defeaters are motivational. But I think that it is far from obvious that there will be defeaters.”

“If Venn diagrams can be thought of as the equivalent of kids’ crayon drawings, then category theory is more akin to the works of Picasso.”

“I listen to all these complaints about rudeness and intemperateness, and the opinion that I come to is that there is no polite way of asking somebody: have you considered the possibility that your entire life has been devoted to a delusion? But that’s a good question to ask. Of course we should ask that question and of course it’s going to offend people. Tough.”

“When will we realize that the fact that we can become accustomed to anything, however disgusting at first, makes it necessary to examine carefully everything we have become accustomed to?”
—George Bernard Shaw, A Treatise on Parents and Children (1910)
“The choice is with us still, but the civilization now in jeopardy is all humanity. As the ancient myth makers knew, we are children equally of the earth and the sky. In our tenure of this planet we’ve accumulated dangerous evolutionary baggage — propensities for aggression and ritual, submission to leaders, hostility to outsiders — all of which puts our survival in some doubt. But we’ve also acquired compassion for others, love for our children and desire to learn from history and experience, and a great soaring passionate intelligence — the clear tools for our continued survival and prosperity. Which aspects of our nature will prevail is uncertain, particularly when our visions and prospects are bound to one small part of the small planet Earth. But up there in the immensity of the Cosmos, an inescapable perspective awaits us. There are not yet any obvious signs of extraterrestrial intelligence and this makes us wonder whether civilizations like ours always rush implacably, headlong, toward self-destruction. National boundaries are not evident when we view the Earth from space. Fanatical ethnic or religious or national chauvinisms are a little difficult to maintain when we see our planet as a fragile blue crescent fading to become an inconspicuous point of light against the bastion and citadel of the stars.”
