Yet I love facts, and hate lubricity and people without perception. Then I have the same title to write on prudence that I have to write on poetry or holiness.

We write from aspiration and antagonism, as well as from experience. We paint those qualities which we do not possess. The poet admires the man of energy and tactics; the merchant breeds his son for the church or the bar; and where a man is not vain and egotistic you shall find what he has not by his praise. Moreover it would be hardly honest in me not to balance these fine lyric words of Love and Friendship with words of coarser sound, and whilst my debt to my senses is real and constant, not to own it in passing.

Prudence is the virtue of the senses. It is the science of appearances. It is the outmost action of the inward life.
