“As technology accumulates and people in more parts of the planet become interdependent, the hatred between them tends to decrease, for the simple reason that you can't kill someone and trade with him too.”

“The world has far too much morality, at least in the sense of activity of people's moral instincts. If you look, and this become clear to me as I tried to identify the causes of violence at various scales throughout human history, from police blotters where the biggest motive for homicide is not just amoral predacious: a smuggler killing someone to steal his Rolex, the biggest categories of motives for homicide are moralistic in the eyes of the perpetrator, of the murderer, is capital punishment: killing someone who deserve to die because: whether is a spouse who's unfaithful or someone who distim him in an argument over a parking space or cheated him in a deal. That's why people kill each other: for moral reasons. That is true as large scales as well.If you'll look up at the largest episodes of bloodletting in human history most of them would have moralistic motives: the nazi Holocaust, Pol Pot, Stalin, the Gulag, Mao, the European war of religions, the Crusades, all of them were killing people for, not because they wanted to accumulate vast amounts of money, or huge harems of women, but because they thought they were acting out of a moral cause.”

“The indispensability of reason does not imply that individual people are always rational or are unswayed by passion and illusion. It only means that people are capable of reason, and that a community of people who choose to perfect this faculty and to exercise it openly and fairly can collectively reason their way to sounder conclusions in the long run. As Lincoln observed, you can fool all of the people some of the time, and you can fool some of the people all of the time, but you can't fool all of the people all of the time.”

“The more you think about and interact with other people, the more you realize that it is untenable to privilege your interests over theirs, at least not if you want them to listen to you. You can’t say that my interests are special compared to yours any more than you can say that the particular spot that I am standing on is a unique part of the universe because I happen to be standing on it that very minute.”

“The Rights Revolutions too have given us ideals that educated people today take for granted but that are virtually unprecedented in human history, such as that people of all races and creeds have equal rights, that women should be free from all forms of coercion, that children should never, ever be spanked, that students should be protected from bullying, and that there’s nothing wrong with being gay. I don’t find it at all implausible that these are gifts, in part, of a refined and widening application of reason.”

“Fiction is empathy technology.”

“Reason is up to these demands because it is an open-ended combinatorial system, an engine for generating an unlimited number of new ideas. Once it is programmed with a basic self-interest and an ability to communicate with others, its own logic will impel it, in the fullness of time, to respect the interests of ever-increasing numbers of others. It is reason too that can always take note of the shortcomings of previous exercises of reasoning, and update and improve itself in response. And if you detect a flaw in this argument, it is reason that allows you to point it out and defend an alternative.”
