“We hear a great deal of talk about idealism, the idealism of America, the idealism of men. There are two conceptions of idealism. If by idealism is meant that a man is so exalted in his purposes that he disregards his own interests from any selfish standpoint and endeavors to benefit other people without trying to benefit himself, that kind of idealism is admirable in an individual. But if by idealism is meant that a man follows visions and dreams, that he does things that are impractical, that will not work out, then that kind of idealism is closely associated with insanity.”
