There is nothing so insupportable to man as to be in entire repose, without passion, occupation, amusement, or application. Then it is that he feels his own nothingness, isolation, insignificance, dependent nature, powerless, emptiness. Immediately there issue from his soul ennui, sadness, chagrin, vexation, despair.
Blaise PascalWe are only troubled by the fears which we, and not nature, give ourselves, for they add to the state in which we are the passions of the state in which we are not.
Blaise Pascal
