Many a profound genius, I suppose, who fills the world with fame of his exploding renowned errors, is yet everyday posed and baffled by trivial questions at his own supper table.
The fatal errors of life are not due to man's being unreasonable: an unreasonable moment may be one's finest moment. They are due to man's being logical.
The only thing that one really knows about human nature is that it changes. Change is the one quality we can predicate of it. The systems that fail are those that rely on the permanency of human nature, and not on its growth and development. The error of Louis XIV was that he thought human nature would always be the same. The result of his error was the French Revolution. It was an admirable result.
Were half the power that fills the world with terror, Were half the wealth bestowed on camps and courts, Given to redeem the human mind from error, There were no need of arsenals or forts.
Who else is it who calls us back from the death of error, except the life that does not know death, and the wisdom which, needing no light, enlightens minds which are in darkness, that wisdom by which the whole world, even to the leaves of trees drifting in the wind, is governed?
I have reached the conviction that the abolition of the death penalty is desirable. Reasons: 1) Irreparability in the event of an error of justice, 2) Detrimental moral influence of the execution procedure on those who, whether directly or indirectly, have to do with the procedure.
Zarathustra was the first to consider the fight of good and evil the very wheel in the machinery of things: the transposition of morality into the metaphysical realm, as a force, cause, and end in itself, is his work. [...] Zarathustra created this most calamitous error, morality; consequently, he must also be the first to recognize it.
