I have no doubt that in reality the future will be vastly more surprising than anything I can imagine. Now my own suspicion is that the Universe is not only queerer than we suppose, but queerer than we can suppose.

Christianity is haunted by the theory of a God with a craving for bloody sacrifices.

It was a reaction from the old idea of "protoplasm", a name which was a mere repository of ignorance.

Religion is still parasitic in the interstices of our knowledge which have not yet been filled. Like bed-bugs in the cracks of walls and furniture, miracles lurk in the lacunae of science. The scientist plasters up these cracks in our knowledge; the more militant Rationalist swats the bugs in the open. Both have their proper sphere and they should realize that they are allies.

Teleology is like a mistress to a biologist: he cannot live without her but he's unwilling to be seen with her in public.

There is no great invention, from fire to flying, which has not been hailed as an insult to some god.

Science is as yet in its infancy, and we can foretell little of the future save that the thing that has not been is the thing that shall be; that no beliefs, no values, no institutions are safe.
