Quidquid luce fuit tenebris agit: but also the other way around. What we experience in dreams, so long as we experience it frequently, is in the end just as much a part of the total economy of our soul as anything we "really" experience: because of it we are richer or poorer, are sensitive to one need more or less, and are eventually guided a little by our dream-habits in broad daylight and even in the most cheerful moments occupying our waking spirit.

Sometimes we remain true to a cause simply because its opponents are unfailingly tasteless.

One unconsciously takes it for granted that doer and sufferer think and feel alike, and according to this supposition we measure the guilt of the one by the pain of the other.

The earth has a skin and that skin has diseases; one of its diseases is called man.

The will to power can express itself only against resistances; it seeks that which resists it--this is the native tendency of theamoeba when it extends its pseudopodia and gropes around.

Improvements are invented only by those who can feel that something is not good.

There is sense in hoping for recognition in a distant future only when we take it for granted that mankind will remain essentially unchanged, and that whatever is great is not for one age only but will be looked upon as great for all time.
