'Take offense at the drop of a hat' is the unwritten eleventh commandment.

If your plane is being hijacked by an armed man who, though prepared to take risks, presumably wants to go on living, there is room for bargaining.

I think that a new kind of replicator has recently emerged on this very planet. It is staring us in the face. It is still in its infancy, still drfiting clumsily about in its primeval soup, but already it is achieving evolutionary change at a rate which leaves the old gene panting far behind.

I think from my point of view - I won't say it doesn't matter whether [Darwinian explanations] are right or wrong, it's just sufficient in some cases, for me, to be able to say, Well, at least it's not totally implausible from a Darwinian point of view.

The list of things about which we strictly have to be agnostic doesn't stop at tooth fairies and celestial teapots. It is infinite. If you want to believe in a particular one of them - teapots, unicorns, or tooth fairies, Thor or Yahweh - the onus is on you to say why you believe in it. The onus is not on the rest of us to say why we do not. We who are atheists are also a-fairyists, a-teapotists, and a-unicornists, but we don't have to bother saying so.

The assignment of purpose to everything is called teleology. Children are native teleologists, and many never grow out of it.

It really comes down to parsimony, economy of explanation. It is possible that your car engine is driven by psychokinetic energy, but if it looks like a petrol engine, smells like a petrol engine and performs exactly as well as a petrol engine, the sensible working hypothesis is that it is a petrol engine.
