In another time and place, that boy could have been me under the stars, dazzled by Orion, Cassiopeia and Ursa Major, tearful with the unheard music of the Milky Way, heady with the night scents of frangipani and trumpet flowers in an African garden. Why the same emotion should have led my chaplain in one direction and me in the other is not an easy question to answer. A quasi-mystical response to nature and the universe is common among scientists and rationalists. It has no connection with supernatural belief. In his boyhood at least, my chaplain was presumably not aware (nor was I) of the closing lines of The Origin of Species — the famous 'entangled bank' passage, 'with birds singing on the bushes, with various insects flitting about, and with worms crawling through the damp earth'. Had he been, he would certainly have identified with it and, instead of the priesthood, might have been led to Darwin's view that all was 'produced by laws acting around us':
Thus, from the war of nature, from famine and death, the most exalted object which we are capable of conceiving, namely, the production of the higher animals, directly follows. There is grandeur in this view of life, with its several powers, having been originally breathed into a few forms or into one; and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved.
Carl Sagan, in Pale Blue Dot, wrote:
How is it that hardly any major religion has looked at science and concluded, 'This is better than we thought! The Universe is much bigger than our prophets said, grander, more subtle, more elegant'? Instead they say, 'No, no, no! My god is a little god, and I want him to stay that way.' A religion, old or new, that stressed the magnificence of the Universe as revealed by modern science might be able to draw forth reserves of reverence and awe hardly tapped by the conventional faiths.
All Sagan's books touch the nerve-endings of transcendent wonder that religion monopolized in past centuries. My own books have the same aspiration. Consequently I hear myself often described as a deeply religious man. An American student wrote to me that she had asked her professor whether he had a view about me. 'Sure,' he replied. 'He's positive science is incompatible with religion, but he waxes ecstatic about nature and the universe. To me, that is religion!' But is 'religion' the right word? I don't think so. The Nobel Prize-winning physicist (and atheist) Steven Weinberg made the point as well as anybody, in Dreams of a Final Theory:
Some people have views of God that are so broad and flexible that it is inevitable that they will find God wherever they look for him. One hears it said that 'God is the ultimate' or 'God is our better nature' or 'God is the universe.' Of course, like any other word, the word 'God' can be given any meaning we like. If you want to say that 'God is energy,' then you can find God in a lump of coal.
Weinberg is surely right that, if the word God is not to become completely useless, it should be used in the way people have generally understood it: to denote a supernatural creator that is 'appropriate for us to worship'.
Much unfortunate confusion is caused by failure to distinguish what can be called Einsteinian religion from supernatural religion. Einstein sometimes invoked the name of God (and he is not the only atheistic scientist to do so), inviting misunderstanding by supernaturalists eager to misunderstand and claim so illustrious a thinker as their own. The dramatic (or was it mischievous?) ending of Stephen Hawking's A Brief History of Time, 'For then we should know the mind of God', is notoriously misconstrued. It has led people to believe, mistakenly of course, that Hawking is a religious man. The cell biologist Ursula Goodenough, in The Sacred Depths of Nature, sounds more religious than Hawking or Einstein. She loves churches, mosques and temples, and numerous passages in her book fairly beg to be taken out of context and used as ammunition for supernatural religion. She goes so far as to call herself a 'Religious Naturalist'. Yet a careful reading of her book shows that she is really as staunch an atheist as I am.
'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).3 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'.4
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.
