'Naturalist' is an ambiguous word. For me it conjures my childhood hero, Hugh Lofting's Doctor Dolittle (who, by the way, had more than a touch of the 'philosopher' naturalist of HMS Beagle about him). In the eighteenth and nineteenth centuries, naturalist meant what it still means for most of us today: a student of the natural world. Naturalists in this sense, from Gilbert White on, have often been clergymen. Darwin himself was destined for the Church as a young man, hoping that the leisurely life of a country parson would enable him to pursue his passion for beetles. But philosophers use 'naturalist' in a very different sense, as the opposite of supernaturalist. Julian Baggini explains in Atheism: A Very Short Introduction the meaning of an atheist's commitment to naturalism:

'What most atheists do believe is that although there is only one kind of stuff in the universe and it is physical, out of this stuff come minds, beauty, emotions, moral values – in short the full gamut of phenomena that gives richness to human life.'

Human thoughts and emotions emerge from exceedingly complex interconnections of physical entities within the brain. An atheist in this sense of philosophical naturalist is somebody who believes there is nothing beyond the natural, physical world, no supernatural creative intelligence lurking behind the observable universe, no soul that outlasts the body and no miracles – except in the sense of natural phenomena that we don't yet understand. If there is something that appears to lie beyond the natural world as it is now imperfectly understood, we hope eventually to understand it and embrace it within the natural. As ever when we unweave a rainbow, it will not become less wonderful.

Great scientists of our time who sound religious usually turn out not to be so when you examine their beliefs more deeply. This is certainly true of Einstein and Hawking. The present Astronomer Royal and President of the Royal Society, Martin Rees, told me that he goes to church as an 'unbelieving Anglican . . . out of loyalty to the tribe'. He has no theistic beliefs, but shares the poetic naturalism that the cosmos provokes in the other scientists I have mentioned. In the course of a recently televised conversation, I challenged my friend the obstetrician Robert Winston, a respected pillar of British Jewry, to admit that his Judaism was of exactly this character and that he didn't really believe in anything supernatural. He came close to admitting it but shied at the last fence (to be fair, he was supposed to be interviewing me, not the other way around). When I pressed him, he said he found that Judaism provided a good discipline to help him structure his life and lead a good one. Perhaps it does; but that, of course, has not the smallest bearing on the truth value of any of its supernatural claims. There are many intellectual atheists who proudly call themselves Jews and observe Jewish rites, perhaps out of loyalty to an ancient tradition or to murdered relatives, but also because of a confused and confusing willingness to label as 'religion' the pantheistic reverence which many of us share with its most distinguished exponent, Albert Einstein. They may not believe but, to borrow Dan Dennett's phrase, they 'believe in belief'.

One of Einstein's most eagerly quoted remarks is 'Science without religion is lame, religion without science is blind.' But Einstein also said,

It was, of course, a lie what you read about my religious convictions, a lie which is being systematically repeated. I do not believe in a personal God and I have never denied this but have expressed it clearly. If something is in me which can be called religious then it is the unbounded admiration for the structure of the world so far as our science can reveal it.
