Injustice in this world is not something comparative; the wrong is deep, clear, and absolute in each private fate.

The aim of life is some way of living, as flexible and gentle as human nature; so that ambition may stoop to kindness, and philosophy to condor and humor. Neither prosperity nor empire nor heaven can be worth winning at the price of a virulent temper, bloody hands, an anguished spirit, and a vain hatred of the rest of the world.

The Universe, so far as we can observe it, is a wonderful and immense engine; its extent, its order, its beauty, its cruelty, makes it alike impressive.

Spirit itself is not human; it may spring up in any life... it may exist in all animals, and who know in how many undreamt-of beings, or in the midst of what worlds?

Wealth, religion, military victory have more rhetorical than efficacious worth.

Sometimes we have to change the truth in order to remember it.

Man's most serious activity is play.
