“I feel as if one would only discover on one's death-bed what one ought to have lived for, and realise too late that one's life has been wasted. Any passionate and courageous life seems good in itself, yet one feels that some element of delusion is involved in giving so much passion to any humanly attainable object. And so irony creeps into the very springs of one's being.”

“One of the most powerful of all our passions is the desire to be admired and respected.”

“One of the painful things about our time is that those who feel certainty are stupid, and those with any imagination and understanding are filled with doubt and indecision.”

“Religious toleration, to a certain extent, has been won, because people have ceased to consider religion so important as it was once thought to be. But in politics and economics, which have taken the place formerly occupied by religion, there is a growing tendency to persecution, which is not by any means confined to one party.”

“With the wise man, what he has does not cease to be enjoyable because some one else has something else. Envy, in fact, is one form of vice, partly moral, partly intellectual, which consists in seeing things never in themselves but only in their relations”

“The life of Man is a long march through the night, surrounded by invisible foes, tortured by weariness and pain, towards a goal that few can hope to reach, and where none may tarry long. One by one, as they march, our comrades vanish form our sight, seized by the silent orders of omnipotent Death. Very brief is the time in which we can help them, in which their happiness or misery is decided. Be it ours to shed sunshine on their path, to lighten their sorrows by the balm of sympathy, to give them the pure joy of a never-tiring affection, to strengthen failing courage, to instill faith in times of despair.”

“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.”
