I am passionate about truth and passionate about clarity, and I don't regard myself as particularly militant or aggressive. I simply wish to discuss what is true and to listen to evidence and put evidence forward to other people and have a sensible, sane, moderated argument.

I don't want to sound callous. I mean, even if I have nothing to offer, that doesn't matter, because that still doesn't mean that what anybody else has to offer therefore has to be true.

The genetic code is not a binary code as in computers, nor an eight-level code as in some telephone systems, but a quaternary code with four symbols. The machine code of the genes is uncannily computerlike.

I think I would abolish schools which systematically inculcate sectarian beliefs.

There is an anaesthetic of familiarity, a sedative of ordinariness which dulls the senses and hides the wonder of existence. For those of us not gifted in poetry, it is at least worth while from time to time making an effort to shake off the anaesthetic. What is the best way of countering the sluggish habitutation brought about by our gradual crawl from babyhood? We can't actually fly to another planet. But we can recapture that sense of having just tumbled out to life on a new world by looking at our own world in unfamiliar ways.

I don't understand why so many people who are sophisticated in science go on believing in God. I wish I did.

A God capable of continuously monitoring and controlling the individual status of every particle in the universe cannot be simple. His existence is going to need a mammoth explanation in its own right.
