Try to acquire the weird practice of savoring your mistakes, delighting in uncovering the strange quirks that led you astray. Then, when you have sucked out all the goodness to be gained from having made them, you can cheerfully forget them and go on to the next big opportunity.

If I were to give a prize for the single best idea anybody ever had, I'd give it to Darwin for the idea of natural selection - ahead of Newton, ahead of Einstein - because his idea unites the two most disparate features of our universe: the world of purposeless, meaningless matter and motion, particles jostling on the one side, and the world of meaning and purpose, design on the other.

People are afraid of being more ignorant than their children―especially, apparantly, their daughters.

We need to let our children grow up to face the world armed with knowledge, with much more knowledge than we ourselves had at their age. It is scary, but the alternative is worse.

Some of the greatest, most revolutionary advances in science have been given their initial expression in attractively modest terms, with no fanfare.

To put it bluntly but fairly, anyone today who doubts that the variety of life on this planet was produced by a process of evolution is simply ignorant — inexcusably ignorant, in a world where three out of four people have learned to read and write.

If the history of resistance to Darwinian thinking is a good measure, we can expect that long into the future, long after every triumph of human thought has been matched or surpassed by 'mere machines,' there will still be thinkers who insist that the human mind works in mysterious ways that no science can comprehend.
