Do not let your fire go out.

A man doesn't borrow pieces of his body. A building doesn't borrow hunks of its soul. Its maker gives it the soul and every wall, window and stairway to express it.

In western civilization, the period ruled by mysticism is known as the 'Dark Ages' and the 'Middle Ages'. I will assume that you know the nature of that period and the state of human existence in those ages. The Renaissance broke the rules of the mystics. "Renaissance" means the "rebirth". Few people today will care to remind you that it was a rebirth of reason - of man's mind.

Do not ever say that the desire to 'do good' by force is a good motive. Neither power-lust nor stupidity are good motives.

Don't bother to examine a folly-ask yourself only what it accomplishes.
