We seldom speak of what we have but often of what we lack. - Arthur Schopenhauer

Human life must be some kind of mistake. The truth of this will be sufficiently obvious if we only remember that man is a compound of needs and necessities hard to satisfy; and that even when they are satisfied, all he obtains is a state of painlessness, where nothing remains to him but abandonment to boredom. This is direct proof that existence has no
real value in itself; for what is boredom but the feeling of the emptiness of life? If life — the craving for which is the very essence of our being — were possessed of any positive intrinsic value, there would be no such thing as boredom at all: mere existence would satisfy us in itself, and we should want for nothing.

Der allgemeine Ueberblick zeigt uns, als die beiden Feinde des menschlichen Glückes, den Schmerz und die Langeweile.

Science is not a taxi-cab that we can get in and out of whenever we like.
