“Or how about this hypothetical definition. Reason is a complex type of instinct that has not yet formed completely. This implies that instinctual behavior is always purposeful and natural. A million years from now our instinct will have matured and we will stop making the mistakes that are probably integral to reason. An then, if something should change in the universe, we will all become extinct - precisely because we will have forgotten how to make mistakes, that is, to try various approaches not stipulated by an inflexible program of permitted alternatives.”

“Because of our broken instincts we are in pain. We continue in pain because our instincts have been twisted by reason. So, what are we supposed to do? Should we abandon knowledge? Throw away reason? In any event, that wouldn't be possible. For better or worse, we ate the fruit of knowledge long, long ago.”

“I'm afraid that we all make mistakes. One of the things that defines our character is how we handle mistakes. If we lie about having made a mistake, then it can't be corrected and it festers. On the other hand, if we give up just because we made a mistake, even a big mistake, none of us would get far in life.”

“A lot of ballads are about the mistakes we inevitably make while trying to figure out how to live our lives.”

“The dinosaurs became extinct because they didn't have a space program. And if we become extinct because we don't have a space program, it'll serve us right!”

“We have to make mistakes, it's how we learn compassion for others.”
