It is only the superficial qualities that last. Man's deeper nature is soon found out.

People say sometimes that Beauty is superficial. That may be so. But at least it is not so superficial as Thought is. To me, Beauty is the wonder of wonders. It is only shallow people who do not judge by appearances. The true mystery of the world is the visible, not the invisible.

Pleasure is Nature's test, her sign of approval. When man is happy, he is in harmony with himself and his environment.

The only thing that one really knows about human nature is that it changes. Change is the one quality we can predicate of it. The systems that fail are those that rely on the permanency of human nature, and not on its growth and development. The error of Louis XIV was that he thought human nature would always be the same. The result of his error was the French Revolution. It was an admirable result.

All art is at once surface and symbol. Those who go beneath the surface do so at their peril.

We have deep depth.
