“Probability is not a mere computation of odds on the dice or more complicated variants; it is the acceptance of the lack of certainty in our knowledge and the development of methods for dealing with our ignorance.”

“The more we learn about the world, and the deeper our learning, the more conscious, specific, and articulate will be our knowledge of what we do not know; our knowledge of our ignorance. For this indeed, is the main source of our ignorance - the fact that our knowledge can be only finite, while our ignorance must necessarily be infinite.”

“What's more, the kaleidoscopic blend of gender-variant and gender-typical traits that characterizes gay people is exactly what enables us to make our own unique contributions to society. It's the reason that we should be valued, celebrated, and welcomed into society rather than merely being tolerated. The aim should be to foster acceptance of gay people as we are, in all our rich diversity and not to seek acceptance by shoe-horning ourselves into conformity with the straight majority.”

“Certainty is the most vivid condition of ignorance and the most necessarycondition for knowledge.”

“The corollary of constant change is ignorance. This is not often talked about: we computer experts barely know what we're doing. We're good at fussing and figuring out. We function well in a sea of unknowns. Our experience has only prepared us to deal with confusion. A programmer who denies this is probably lying, or else is densely unaware of himself.”

“All our knowledge merely helps us to die a more painful death than the animals that know nothing.”
