a generation that cannot endure boredom will be a generation of little men, of men unduly divorced from the slow process of nature, of men in whom every vital impulse slowly withers as though they were cut flowers in a vase. Bertrand Russell
The true dualism I take to be the contrast between two wills, one of which is felt as vital impulse (élan vital) and the other as vital control (frein vital). Irving Babbitt
