In the distant future I see open fields for far more important researches. Psychology will be based on a new foundation, that of the necessary acquirement of each mental power and capacity by gradation. Light will be thrown on the origin of man and his history.

Nobody can think straight who does not work. Idleness warps the mind.

One receives as reward for much ennui, despondency, boredom-such as a solitude without friends, books, duties, passions must bring with it-those quarter-hours of profoundest contemplation within oneself and nature. He who completely entrenches himself against boredom also entrenches himself against himself: he will never get to drink the strongest refreshing draught from his own innermost fountain.

The greatest events - they are not our loudest but our stillest hours.

Every man should ask himself each day whether he is not too readily accepting negative solutions.

Open your eyes, look within. Are you satisfied with the life you're living?
