I have never quite understood - and this is no doubt my failing - I never quite understood why you would read fiction to understand the human condition.

If we want to postulate a deity capable of engineering all the organized complexity in the world, either instantaneously or by guiding evolution, that deity must have been vastly complex in the first place. The creationist, whether a naive Bible-thumper or an educated bishop, simply postulates an already existing being of prodigious intelligence and complexity. If we are going to allow ourselves the luxury of postulating organized complexity without offering an explanation, we might as well make a job of it and simply postulate the existence of life as we know it!

People who believe the earth was created 6000 years ago, when it's actually 4.5 billion years old, should also believe the width of North America is 8 yards. That is the scale of the error.

The obvious objections to the execution of Saddam Hussein are valid and well aired. His death will provoke violent strife between Sunni and Shia Muslims, and between Iraqis in general and the American occupation forces.

Our leaders have described the recent atrocity with the customary cliche: mindless cowardice. Mindless may be a suitable word for the vandalising of a telephone box. It is not helpful for understanding what hit New York on September 11. Those people were not mindless and they were certainly not cowards. On the contrary, they had sufficiently effective minds braced with an insane courage, and it would pay us mightily to understand where that courage came from. It came from religion.

You can't even begin to understand biology, you can't understand life, unless you understand what it's all there for, how it arose - and that means evolution.

The human psyche has two great sicknesses: the urge to carry vendetta across generations, and the tendency to fasten group labels on people rather than see them as individuals.
