Polytheism, or that aspect of paganism, was never to the pagan what Catholicism is to the Catholic. It was never a view of the universe satisfying all sides of life; a complete and complex truth with something to say about everything. It was only a satisfaction of one side of the soul of man, even if we call it the religious side; and I think it is truer to call it the imaginative side. But this it did satisfy; in the end it satisfied it to satiety. All that world was a tissue of interwoven tales and cults, and there ran in and out of it, as we have already seen, that black thread among its more blameless colours: the darker paganism that was really diabolism. But we all know that this did not mean that all pagan men thought of nothing but pagan gods. Precisely because mythology only satisfied one mood, they turned in other moods to something totally different. But it is very important to realise that it was totally different. It was too different to be inconsistent. It was so alien that it did not clash. While a mob of people were pouring on a public holiday to the feast of Adonis or the games in honour of Apollo, this or that man would prefer to stop at home and think out a little theory about the nature of things. Sometimes his hobby would even take the form of thinking about the nature of God; or even in that sense about the nature of the gods. But he very seldom thought of pitting his nature of the gods against the gods of nature. It is necessary to insist on this abstraction in the first student of abstractions. He was not so much antagonistic as absent-minded. His hobby might be the universe; but at first the hobby was as private as if it had been numismatics or playing draughts. And even when his wisdom came to be a public possession, and almost a political institution, it was very seldom on the same plane as the popular and religious institutions. Aristotle, with his colossal common sense, was perhaps the greatest of all philosophers; certainly the most practical of all philosophers. But Aristotle would no more have set up the Absolute side by side with the Apollo of Delphi, as a similar or rival religion, than Archimedes would have thought of setting up the Lever as a sort of idol or fetish to be substituted for the Palladium of the city. Or we might as well imagine Euclid building an altar to an isosceles triangle, or offering sacrifices to the square on the hypotenuse. The one man meditated on metaphysics as the other man did on mathematics; for the love of truth or for curiosity or for the fun of the thing. But that sort of fun never seems to have interfered very much with the other sort of fun; the fun of dancing or singing to celebrate some rascally romance about Zeus becoming a bull or a swan. It is perhaps the proof of a certain superficiality and even insincerity about the popular polytheism, that men could be philosophers and even sceptics without disturbing it. These thinkers could move the foundations of the world
