Let me lay my cards on the table. If I were to give an award for the single best idea anyone ever had, I'd give it to Darwin, ahead of even Newton or Einstein and everyone else. In a single stroke, the idea of evolution by natural selection unifies the realm of life, meaning, and purpose with the realm of space and time, cause and effect, mechanism and physical law. It is not just a wonderful idea. It is a dangerous idea.
Daniel DennettThe kindly God who lovingly fashioned each and every one of us and sprinkled the sky with shining stars for our delight - that God is, like Santa Claus, a myth of childhood, not anything [that] a sane, undeluded adult could literally believe in. That God must either be turned into a symbol for something less concrete or abandoned altogether.
Daniel DennettCults and prophets proclaiming the imminent end of the world have been with us for several millennia, and it has been another sour sort of fun to ridicule them the morning after, when they discover that their calculations were a little off. But, just as with Marxists, there are some among them who are working hard to "hasten the inevitable," not merely anticipating the End Days with joy in their hearts, but taking political action to bring about the conditions they think are the prerequisites for that occasion.
Daniel DennettMy faith in the expertise of physicists like Richard Feynman, for instance, permits me to endorseโand, if it comes to it, bet heavily on the truth ofโa proposition that I don't understand. So far, my faith is not unlike religious faith, but I am not in the slightest bit motivated to go to my death rather than recant the formulas of physics. Watch: E doesn't equal mc2, it doesn't, it doesn't! I was lying, so there!
