Art is either plagiarism or revolution.

It is the eye of ignorance that assigns a fixed and unchangeable color to every object; beware of this stumbling block.

Life being what it is, one dreams of revenge.

There is always a heavy demand for fresh mediocrity. In every generation the least cultivated taste has the largest appetite.

Life is hardly more than a fraction of a second. Such a little time to prepare oneself for eternity!

Civilization is what makes you sick.

Life has no meaning unless one lives it with a will, at least to the limit of one's will. Virtue, good, evil are nothing but words, unless one takes them apart in order to build something with them; they do not win their true meaning until one knows how to apply them.

Stressing output is the key to improving productivity, while looking to increase activity can result in just the opposite.
