“But complex animals had obtained their adaptive flexibility at some cost--they had traded one dependency for another. It was no longer necessary to change their bodies to adapt, because now their adaptation was behavior, socially determined. That behavior required learning. In a sense, among higher animals adaptive fitness was no longer transmitted to the next generation by DNA at all. It was now carried by teaching.”

“For our own species, evolution occurs mostly through our behavior. We innovate new behavior to adapt.”

“The purpose of life is to stay alive. Watch any animal in nature--all it tries to do is stay alive. It doesn't care about beliefs or philosophy. Whenever any animal's behavior puts it out of touch with the realities of its existence, it becomes exinct.”

“Like it or not, I'm here now, in the year 1Q84. The 1984 that I knew no longer exists. It's 1Q84 now. The air has changed, the scene has changed. I have to adapt to this world-with-a-question-mark as soon as I can. Like an animal released into a new forest. In order to protect myself and survive, I have to learn the rules of this place and adapt myself to them.”

“What makes you think human beings are sentient and aware? There's no evidence for it. Human beings never think for themselves, they find it too uncomfortable. For the most part, members of our species simply repeat what they are told-and become upset if they are exposed to any different view. The characteristic human trait is not awareness but conformity, and the characteristic result is religious warfare. Other animals fight for territory or food; but, uniquely in the animal kingdom, human beings fight for their 'beliefs.' The reason is that beliefs guide behavior which has evolutionary importance among human beings. But at a time when our behavior may well lead us to extinction, I see no reason to assume we have any awareness at all. We are stubborn, self-destructive conformists. Any other view of our species is just a self-congratulatory delusion. Next question.”

“And the most successful people are those who accept, and adapt to, constant change. This adaptability requires a degree of flexibility and humility most people can't manage.”

“All human behavior has a reason. All behavior is solving a problem.”
