“Too often, the notion of progress is used as a code word for perfection, the chain of being in a different guise. The term should be employed with caution. Some see an arrow of time in biology, as in physics, but in the opposite direction- a relentless tendency to improve, just as a universe has a built-in trend towards chaos and disorder. That is too optimistic. Some lineages get more complicated, some simpler, and much of life has to struggle to stay in the same place. If everyone is evolving, nobody can afford to stop, and there may be constant change with no overall advance at all. ”

“Some properties should not be changed. The Answer to Life, the Universe, and Everything is 42, and you want it to stay that way. Error and status flags will often be hard-coded into your classes. Although they should be publicly and statically available, client code should not be able to change them.”

“The universe danced towards life. Life was a remarkably common commodity. Anything sufficiently complicated seemed to get cut in for some, in the same way that anything massive enough got a generous helping of gravity. The universe had a definite tendency towards awareness. This suggested a certain subtle cruelty woven into the very fabric of space-time.”

“I eventually realized that some of us carry a lot and some of us not so much. And it changes at different times of our lives. If your shopping cart is too full, is more than you can maneuver through life, then it's not my place or anyone else's place to say you should've been stronger, been able to carry more.”

“How much more generous it would be if, instead of writing parables about childhood wounds, psychologists were to accept that some differences between the sexes just are, that they are in the nature of the beasts, because each sex has an evolved tendency to develop that way in response to experience.”

“Some of us, I imagine, write out of anger; some out of pain; some write out of prejudice or loss, some out of passion, the promise of something better, perhaps the belief that—even now—a book can be capable of changing a life. Some of us write to remember, some to forget; some to change things, some to ensure things stay the same. Some of us—as my editor and agent will all too easily testify—write because we cannot stop.”
