History is always repeating itself, but each time the price goes up.

Every science begins as philosophy and ends as art; it arises in hypothesis and flows into achievement.

Historically the belief in heaven and the belief in utopia are like compensatory buckets in a well: when one goes down the other comes up. When the classic religions decayed, communistic agitation rose in Athens (430 B.C.), and revolution began in Rome (133 B.C.); when these movements failed, resurrection faiths succeeded, culminating in Christianity; when, in our eighteenth century, Christian belief weakened, communism reappeared. In this perspective the future of religion is secure.

There is no real philosophy until the mind turns around and examines itself.

Wherever men do things, other men will arise who will explain to them how things should be done.

Cultivate your garden. Do not depend upon teachers to educate you... follow your own bent, pursue your curiosity bravely, express yourself, make your own harmony.

To seek, beneath the universal strife, the hidden harmony of things.
