Conquest of Happiness, Excitement and Boredom

"Love is an experience in which our whole being is renewed and refreshed as is that of plants by rain after drought. In sex intercourse without love there is nothing of this. When the momentary pleasure is ended, there is fatigue, disgust, and a sense that life is hollow. Love is part of the life of Earth; sex without love is not."

Bertrand Russell, 1930.
