I suppose if you look back to your early childhood you accept everything people tell you, and that includes a heavy dose of irrationality - you're told about tooth fairies and Father Christmas and things.
For the first half of geological time our ancestors were bacteria. Most creatures still are bacteria, and each one of our trillions of cells is a colony of bacteria.
We humans are an extremely important manifestation of the replication bomb, because it is through us - through our brains, our symbolic culture and our technology - that the explosion may proceed to the next stage and reverberate through deep space.
Science coverage could be improved by the recognition that science is timeless, and therefore science stories should not need to be pegged to an item in the news.
Of course in science there are things that are open to doubt and things need to be discussed. But among the things that science does know, evolution is about as certain as anything we know.
The enlightenment is under threat. So is reason. So is truth. So is science, especially in the schools of America.
I am one of those scientists who feels that it is no longer enough just to get on and do science. We have to devote a significant proportion of our time and resources to defending it from deliberate attack from organised ignorance.
It has become almost a cliche to remark that nobody boasts of ignorance of literature, but it is socially acceptable to boast ignorance of science and proudly claim incompetence in mathematics.
Isn't it sad to go to your grave without ever wondering why you were born? Who, with such a thought, would not spring from bed, eager to resume discovering the world and rejoicing to be part of it?
There may be fairies at the bottom of the garden. There is no evidence for it, but you can't prove that there aren't any, so shouldn't we be agnostic with respect to fairies?
It would be intolerant if I advocated the banning of religion, but of course I never have.
Many of us saw religion as harmless nonsense. Beliefs might lack all supporting evidence but, we thought, if people needed a crutch for consolation, where's the harm? September 11th changed all that.
One of the things that is wrong with religion is that it teaches us to be satisfied with answers which are not really answers at all.
I am against religion because it teaches us to be satisfied with not understanding the world.
Religion is about turning untested belief into unshakable truth through the power of institutions and the passage of time.
I love romantic poetry.
The Bible should be taught, but emphatically not as reality. It is fiction, myth, poetry, anything but reality. As such it needs to be taught because it underlies so much of our literature and our culture.
Nothing is wrong with peace and love. It is all the more regrettable that so many of Christ's followers seem to disagree.
Complex, statistically improbable things are by their nature more difficult to explain than simple, statistically probable things.
I'm not one of those who wants to purge our society of our Christian history.
