“Don't flatter yourself that friendship authorizes you to say disagreeable things to your intimates. The nearer you come into relation with a person, the more necessary do tact and courtesy become. Except in cases of necessity, which are rare, leave your friend to learn unpleasant things from his enemies; they are ready enough to tell them.”

“For I say to you in all the sadness of conviction, that to think great thoughts you must be heroes as well as idealists. Only when you have worked alone – when you have felt around you a black gulf of solitude more isolating than that which surrounds the dying man, and in hope and in despair have trusted to your own unshaken will – then only will you have achieved. Thus only can you gain the secret isolated joy of the thinker, who knows that, a hundred years after he is dead and forgotten, men who have never heard of him will be moving to the measure of his thought – the subtle rapture of a postponed power, which the world knows not because it has no external trappings, but which to his prophetic vision is more real than that which commands an army.”

“The mind of a bigot is like the pupil of the eye. The more light you shine on it, the more it will contract.”

“If I had a formula for bypassing trouble, I wouldn't pass it around. Wouldn't be doing anybody a favor. Trouble creates a capacity to handle it. I don't say embrace trouble. That's as bad as treating it as an enemy. But I do say, meet it as a friend, for you'll see a lot of it and had better be on speaking terms with it.”

“Certitude is not the test of certainty. We have been cocksure of many things that were not so.”

“We must think things not words, or at least we must constantly translate our words into the facts for which they stand, if we are to keep to the real and the true.”
