It is raining DNA outside. On the bank of the Oxford canal at the bottom of my garden is a large willow tree, and it is pumping downy seeds into the air. ... spreading DNA whose coded characters spell out specific instructions for building willow trees that will shed a new generation of downy seeds. ... It is raining instructions out there; it's raining programs; it's raining tree-growing, fluff-spreading, algorithms. That is not a metaphor, it is the plain truth. It couldn't be any plainer if it were raining floppy discs.

There is something wrong with using faith - belief without evidence - as a political weapon. I wouldn't say there is something similar about using science. Science - or the products of science like technology - is just a way of achieving something real, something that happens, something that works.

I'd like everybody to be secular. I suppose I have to say politically I would like religion to become gentler and nicer and to stop interfering with other people's lives, stop repressing women, stop indoctrinating children, all that sort of thing. But I really, really would like to see religion go away altogether.

The psychologist Elizabeth Loftus has shown great courage, in the face of spiteful vested interests, in demonstrating how easy it is for people to concoct memories that are entirely false but which seem, to the victim, every bit as real as true memories.

Gould carried the art of bending over backward to positively supine lengths. Why shouldn't we comment on God, as scientists? ... A universe with a creative superintendent would be a very different kind of universe from one without. Why is that not a scientific matter?

Scientific and technological progress themselves are value-neutral. They are just very good at doing what they do. If you want to do selfish, greedy, intolerant and violent things, scientific technology will provide you with by far the most efficient way of doing so. But if you want to do good, to solve the world's problems, to progress in the best value-laden sense, once again, there is no better means to those ends than the scientific way.

I think a fundamentalist is somebody who believes something unshakably and isn't going to change their mind.
