Intellect is invisible to the man who has none. - Arthur Schopenhauer

Boredom is certainly not an evil to be taken lightly: it will ultimately etch lines of true despair onto a face. It makes beings with as little love for each other as humans nonetheless seek each other with such intensity, and in this way becomes the source of sociability.

:Kurz ist der Schmerz, unendlich ist die Freude.

The charlatan takes very different shapes according to circumstances; but at bottom he is a man who cares nothing about knowledge for its own sake, and only strives to gain the semblance of it that he may use it for his own personal ends, which are always selfish and material.
