A belief is not true because it is useful

True humility is contentment.

Let us be true: this is the highest maxim of art and of life, the secret of eloquence and of virtue, and of all moral authority.

Order is a great person's need and their true well being.

I'm not interested in age. People who tell me their age are silly. You're as old as you feel.

Why not grow something useful, like potatoes?
