Richard Dawkins on Knowledge

"University is about confronting new ideas, unfamiliar, un-"safe". If you want to be "safe" you are not worthy of a university education."

"You know you've won the argument when the only counter argument they can find is that you are white or male or old."

"Darwin made it possible to be an intellectually fulfilled atheist."

"This is one of the hardest lessons for humans to learn. We cannot admit that things might be neither good nor evil, neither cruel nor kind, but simply callous – indifferent to all suffering, lacking all purpose."

"I can't be sure God does not exist... On a scale of seven, where one means I know he exists, and seven I know he doesn't, I call myself a six... That doesn't mean I'm absolutely confident, that I absolutely know, because I don't."

"Mild paedophilia is bad. Violent paedophilia is worse. If you think that's an endorsement of mild paedophilia, go away and learn how to think. Date rape is bad. Stranger rape at knifepoint is worse. If you think that's an endorsement of date rape, go away and learn how to think."

"On the properties of God: "Such a bandwidth! God, who may not have a brain made of neurons, or a CPU made of silicon, but if he has the powers attributed to him he must have something far more elaborately and non-randomly constructed than the largest brain or the largest computer we know."

"Never say, and never take seriously anyone who says, "I cannot believe that so-and-so could have evolved by gradual selection". I have dubbed this kind of fallacy "the Argument from Personal Incredulity". Time and again, it has proven the prelude to an intellectual banana-skin experience."

"If we want to know where the truth lies in particular cases, we have to look. What the Darwinian corpus gives us is not detailed expectations about particular organisms. It gives us something subtler and more valuable: understanding of principle. But if we must have myths, the real facts about vampires could tell a different moral tale."

"The fact that something is written down is persuasive to people not used to asking questions like: ‘Who wrote it, and when?’ ‘How did they know what to write?’ ‘Did they, in their time really mean what we, in our time, understand them to be saying?’ ‘Were they unbiased observers, or did they have an agenda that coloured their writing?’."

"Even sticking to the higher plane of love, is it so very obvious that you can't love more than one person? We seem to manage it with parental love , love of books, of food, of wine , love of composers, poets, holiday beaches, friends . . . why is erotic love the one exception that everybody instantly acknowledges without even thinking about it?"

"Ten years ago, you could have traveled thousands of miles through the United States and never seen a baseball cap turned back to front. Today, the reverse baseball cap is ubiquitous. I do not know what the pattern of geographical spread of the reverse baseball cap precisely was, but epidemiology is certainly among the professions primarily qualified to study it."

"You could give Aristotle a tutorial. And you could thrill him to the core of his being. Aristotle was an encyclopedic polymath, an all time intellect. Yet not only can you know more than him about the world, you also can have a deeper understanding of how everything works. Such is the privilege of living after Newton, Darwin, Einstein, Planck, Watson, Crick and their colleagues."

"I think it is not helpful to apply Darwinian language too widely. Conquest of nation by nation is too distant for Darwinian explanations to be helpful. Darwinism is the differential survival of self-replicating genes in a gene pool, usually as manifested by individual behaviour, morphology, and phenotypes. Group selection of any kind is not Darwinism as Darwin understood it nor as I understand it. There is a very vague analogy between group selection and conquest of a nation by another nation, but I don't think it's a very helpful analogy. So I would prefer not to invoke Darwinian language for that kind of historical interpretation."
