“If most of us are ashamed of shabby clothes and shoddy furniture let us be more ashamed of shabby ideas and shoddy philosophies.... It would be a sad situation if the wrapper were better than the meat wrapped inside it.”

“I feel compelled to say something else to you. There has been a certain ill-feeling between us the cause of which I do not want to analyze. I have struggled against the feeling of bitterness attached to it, with complete success. I think of you again with unmixed geniality and ask you to try to do the same with me. It is a shame when two real fellows who have extricated themselves somewhat from this shabby world do not afford each other mutual pleasure.”

“I would not think that philosophy and reason themselves will be man's guide in the foreseeable future; however, they will remain the most beautiful sanctuary they have always been for the select few.”

“The most beautiful thing we can experience is the mysterious. It is the source of all true art and science. He to whom the emotion is a stranger, who can no longer pause to wonder and stand wrapped in awe, is as good as dead —his eyes are closed. The insight into the mystery of life, coupled though it be with fear, has also given rise to religion. To know what is impenetrable to us really exists, manifesting itself as the highest wisdom and the most radiant beauty, which our dull faculties can comprehend only in their most primitive forms—this knowledge, this feeling is at the center of true religiousness.”

“What a sad era when it is easier to smash an atom than a prejudice.”

“We act as though comfort and luxury were the chief requirements of life. All that we need to make us happy is something to be enthusiastic about.”

“Love is a better master than duty.”
