“Machines deprive us of two things which are certainly important ingredients of human happiness, namely, spontaneity and variety.”

“The main things which seem to me important on their own account, and not merely as means to other things, are knowledge, art, instinctive happiness, and relations of friendship or affection.”

“Understanding human nature must be the basis of any real improvement in human life. Science has done wonders in mastering the laws of the physical world, but our own nature is much less understood, as yet, than the nature of stars and electrons. When science learns to understand human nature, it will be able to bring a happiness into our lives which machines and the physical sciences have failed to create.”

“To like many people spontaneously and without effort is perhaps the greatest of all sources of personal happiness.”

“This [Hegel's philosophy] illustrates an important truth, namely, that the worse your logic, the more interesting the consequences to which it gives rise.”

“a certain amount of boredom is...essential to a happy life”

“There lies before us, if we choose, continual progress in happiness, knowledge and wisdom. Shall we instead choose death, because we cannot forget our quarrels? I appeal as a human being to human beings; remember your humanity, and forget the rest.”
