No guilt is forgotten so long as the conscience still knows of it.

Fate is never too generous even to its favorites. Rarely do the gods grant a mortal more than one immortal deed.

It would be foolhardy to count on the conscience of the world.

Nothing that has ever been thought and said with a clear mind and pure ethical strength is totally in vain; even if it comes froma weak hand and is imperfectly formed, it inspires the ethical spirit to constantly renewed creation.

But don't despise error. When touched by genius, when led by chance, the most superior truth can come into being from even the most foolish error. The important inventions which have been brought about in every realm of science from false hypotheses number in the hundreds, indeed in the thousands.

Every epoch which seeks renewal first projects its ideal into a human form. In order to comprehend its own essence tangibly, the spirit of the time chooses a human being as its prototype and raising this single individual, often one upon whom it has chanced to come, far beyond his measure, the spirit enthuses itself for its own enthusiasm.

Only the person who has experienced light and darkness, war and peace, rise and fall, only that person has truly experienced life.
