Perhaps this is why we feel so drawn to trees. Groves of redwoods and beeches are often compared to the naves of great cathedrals: the silence; the green, filtered, numinous light. A single banyan, each with its multitude of trunks, is like a temple or a mosque – a living colonnade. But the metaphor should be the other way around. The cathedrals and mosques emulate the trees. The trees are innately holy. Christians with their one omnipotent God may take exception to such pagan musings; but the totaras and the kauris were sacred to the Maoris, and the banyan and bodhi and the star-flowered temple trees (and many, many others) to Hindus and Buddhist, and the roots of this reverence, one feels, run back not simply to the enlightenment of Buddha as he sat beneath a bo tree (in 528 BC, tradition has it), but to the birth of humanity.
But Christianity did give rise to modern science. The roots of science run far back in time and from all directions – from the Babylonians, the Greeks, many great Arab scholars in what Europeans call the Middle Ages, the Indians, the Chinese, the Jews, and the much underappreciated natural history of all hunter-gatherers and subsistence farmers everywhere. But it was the Christians from the thirteenth century onwards, with an obvious climax in the seventeenth, who gave us science in a recognisably modern form. The birth of modern science is often portrayed by secular philosophers as the ‘triumph’ of ‘rationality’ over religious ‘superstition’. But it was much more subtle and interesting than that. The great founders of modern thinking – Galileo, Newton, Leibniz, Descartes, Robert Boyle, the naturalist John Ray – were all devout. For them (as Newton put the matter) science was the proper use of the God-given intellect, the better to appreciate the works of God. Pythagoras, five centuries before Christ, saw science (as he then construed it) as a divine pursuit. Galileo, Newton, Ray and the rest saw their researches as a form of reverence.
