James Stephens

"The only trouble the body can know is disease. All other miseries come from the brain, and, as these belong to thought, they can be driven out by their master as unruly and unpleasant vagabonds; for a mental trouble should be spoken to, confronted, reprimanded and so dismissed. The brain cannot afford to harbor any but pleasant and eager citizens who will do their part in making laughter and holiness for the world, for that is the duty of thought."

"Young people are fools in their heads and old people are fools in their hearts, and they can only look at each other and pass by in wonder."
