“For man to become successful, for man to establish himself as the ruler of the planet, it was necessary for him to use his brain as something more than a device to make the daily routine of getting food and evading enemies a little more efficient. Man had to learn to control his environment.”
"The Tragedy of the Moon," The Magazine of Fantasy and Science Fiction (July 1972)

The Analects, The Doctrine of the Mean
Context: It is the way of the superior man to prefer the concealment of his virtue, while it daily becomes more illustrious, and it is the way of the mean man to seek notoriety, while he daily goes more and more to ruin. It is characteristic of the superior man, appearing insipid, yet never to produce satiety; while showing a simple negligence, yet to have his accomplishments recognized; while seemingly plain, yet to be discriminating. He knows how what is distant lies in what is near. He knows where the wind proceeds from. He knows how what is minute becomes manifested. Such a one, we may be sure, will enter into virtue.

“Nothing would more contribute to make a Man wise, than to have always an Enemy in his view.”
