The biologist can push it back to the original protist, and the chemist can push it back to the crystal, but none of them touch the real question of why or how the thing began at all. The astronomer goes back untold million of years and ends in gas and emptiness, and then the mathematician sweeps the whole cosmos into unreality and leaves one with mind as the only thing of which we have any immediate apprehension. Cogito ergo sum, ergo omnia esse videntur. All this bother, and we are no further than Descartes. I suppose that perpetually contemplating things on so vast a scale makes them feel either that it doesn't matter a hoot anyway, or that anything so large and elaborate must have some sense in it somewhere.
Science is always wrong.
It never solves a problem without creating ten more. When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is most probably wrong. Clarke's First Law When the lay public rallies round to an idea that is denounced by distinguished by elderly scientists and supports the idea with great fervour and emotion, the distinguished but elderly scientests are then, after all, right. The eternal mystery of the world is its comprehensibility.
