From “On the Wit of Whistler” in Heretics:
Unquestionably it is a very common phrase of modern intellectualism to say that the morality of one age can be entirely different to the morality of another. And like a great many other phrases of modern intellectualism, it means literally nothing at all. If the two moralities are entirely different, why do you call them both moralities? It is as if a man said, “Camels in various places are totally diverse; some have six legs, some have none, some have scales, some have feathers, some have horns, some have wings, some are green, some are triangular. There is no point which they have in common.”…Of course, there is a permanent substance of morality, as much as there is a permanent substance of art; to say that is only to say that morality is morality and art is art.
