For more than a century, people have often thought that the conclusion to draw from Darwin's vision is that Homo sapiens, our species - and we're just animals too, we're just mammals - that there is nothing morally special about us. I myself don't think this follows at all from Darwin's vision, but it is certainly the received view in many quarters.

... there could be talking bunny rabbits, spiders who write English messages in their webs, and for that matter, melancholy choo-choo trains. There could be, I suppose, but there aren't-so my theory doesn't have to explain them.

Isn't it true that whatever isn't determined by our genes must be determined by our environment? What else is there? There's Nature and there's Nurture. Is there also some X, some further contributor to what we are? There's Chance. Luck. This extra ingredient is important but doesn't have to come from the quantum bowels of our atoms or from some distant star. It is all around us in the causeless coin-flipping of our noisy world, automatically filling in the gaps of specification left unfixed by our genes, and unfixed by salient causes in our environment.

Sometimes you don’t just want to risk making mistakes; you actually want to make them - if only to give you something clear and detailed to fix.

Now that mobile phones and the internet have altered the epistemic selective landscape in a revolutionary way, every religious organisation must scramble to evolve defences or become extinct.

You don't get to advertise all the good that your religion does without first scrupulously subtracting all the harm it does and considering seriously the question of whether some other religion, or no religion at all, does better.

The evidence for evolution pours in, not only from geology, paleontology, biogeography, and anatomy, but of course from molecular biology and every other branch of the life sciences.
