Denied the outlet, through play, of his energies, he recoiled upon himself and developed his mental processes. He became cunning; he had idle time in which to devote himself to thoughts of trickery.

I do not live for what the world thinks of me, but for what I think of myself.

Life creeps slowly upward.... When some forgotten inventor of the older world smote his rival or enemy with a branch of wood and found that it was good and thereafter made a practice of smiting rivals and enemies with branches of wood, then, and on that day, artificiality may be said to have begun. Then, and on that day, was begun a revolution destined to change the history of life. Then, and on that day, was laid the cornerstone of that most tremendous of artifices, CIVILIZATION!

Deep in the forest a call was sounding, and as often as he heard this call, mysteriously thrilling and luring, he felt compelled to turn his back upon the fire and the beaten earth around it, and to plunge into the forest, and on and on, he knew not where or why; nor did he wonder where or why, the call sounding imperiously, deep in the forest.

I early learned that there were two natures in me. This caused me a great deal of trouble, till I worked out a philosophy of life and struck a compromise between the flesh and the spirit. Too great an ascendancy of either was to be abnormal, and since normality is almost a fetish of mine, I finally succeeded in balancing both natures. Ordinarily they are at equilibrium; yet as frequently as one is permitted to run rampant, so is the other. I have small regard for an utter brute or for an utter saint.

To be able to forget means sanity.
