Ordinary people merely think how they shall 'spend' their time; a man of talent tries to 'use' it. - Arthur Schopenhauer

The animals are much more content with mere existence than we are; the plants are wholly so; and man is so according to how dull and insensitive he is. The animal’s life consequently contains less suffering but also less pleasure than the human’s, the direct reason being that on the one hand it is free from care and anxiety and the torments that attend them, but on the other is without hope and therefore has no share in that anticipation of a happy future which, together with the enchanting products of the imagination which accompany it, is the source of most of our greatest joys and pleasures. The animal lacks both anxiety and hope because its consciousness is restricted to what is clearly evident and thus to the present moment: the animal is the present incarnate.

In the sphere of thought, absurdity and perversity remain the masters of the world, and their dominion is suspended only for brief periods.

It may sometimes happen that a truth, an insight, which you have slowly and laboriously puzzled out by thinking for yourself could have easily have been found already written in a book: but it is a hundred times more valuable if you have arrived at it by thinking for yourself. For only then will it enter your thought system as an integral part and living member, be perfectly and firmly consistent with it and in accord with all its other consequences and conclusions, bear the hue, colour and stamp of your whole manner of thinking, and have arrived at just the moment it was needed ; thus it will stay firmly and forever lodged in your mind.
