All that causes one man to differ from another is a very slight thing. What is it that is the origin of beauty or ugliness, health or weakness, ability or stupidity? A slight difference in the organs, a little more or a little less bile. Yet this more or less is of infinite importance to men; and when they think otherwise they are mistaken.
Luc de ClapiersMost people grow old within a small circle of ideas, which they have not discovered for themselves. There are perhaps less wrong-minded people than thoughtless.
