„To try to be happy is to try to build a machine with no other specification than that it shall run noiselessly.“

Contexte: Everyone wants rather to be pleasing to women and that desire is not altogether, though it is very largely, a manifestation of vanity. But one cannot aim to be pleasing to women any more than one can aim to have taste, or beauty of expression, or happiness; for these things are not specific aims which one may learn to attain; they are descriptions of the adequacy of one's living. To try to be happy is to try to build a machine with no other specification than that it shall run noiselessly.
