"What saves a man is to take a step. Then another step."

"Man's "progress" is but a gradual discovery that his questions have no meaning"

"The machine does not isolate man from the great problems of nature but plunges him more deeply into them."

“I have no right to say or do anything that diminishes a man in his own eyes. What matters is not what I think of him but what he thinks of himself. Hurting a man in his dignity is a crime.” 

"To be a man is to be responsible. It is to feel shame at the sight of what seems to be unmerited misery. It is to take pride in a victory won by one's comrades. It is to feel, when setting one's stone, that one is contributing to the building of the world."

"Once men are caught up in an event, they cease to be afraid. Only the unknown frightens men."

The goal is not to be better than the other man, but your previous self.

A spoon cannot taste of the food it carries. Likewise, a foolish man cannot understand the wise man’s wisdom even if he associates with a sage.

For men, I think, love is a thing formed of equal parts lust and astonishment. The astonishment part women understand. The lust part they only think they understand.

love is what moves the world, I've always thought...it is the only thing which allows men and women to stand in a world where gravity always seems to want to pull them down...bring them low...and make them crawl...

A new type of thinking is essential if mankind is to survive and move toward higher levels.
