The famous balance of nature is the most extraordinary of all cybernetic systems. Left to itself, it is always self-regulated.

To have passed through life and never experienced solitude is to have never known oneself. To have never known oneself is to have never known anyone.

If people destroy something replaceable made by mankind, they are called vandals; if they destroy something irreplaceable made by God, they are called developers.

There is no such thing as a dangerous woman; there are only susceptible men.

The impulse to mar and to destroy is as ancient and almost as nearly universal as the impulse to create. The one is an easier way than the other of demonstrating power.

Is it wholly fantastic to admit the possibility that Nature herself strove toward what we call beauty? Face to face with any one of the elaborate flowers which man's cultivation has had nothing to do with, it does not seem fantastic to me. We put survival first. But when we have a margin of safety left over, we expend it in the search for the beautiful. Who can say that Nature does not do the same?

There is no conceivable human action which custom has not at one time justified and at another condemned.
