A CARPENTER doth not come and say, "Hear me discourse on the art of building"; but he hires a house and fits it up and shows himself master of his trade. Let it be your business likewise to do something like this: eat like a man; drink, dress, marry, have children, perform the duty of a citizen; bear reproach; bear with an unreasonable brother; bear with a father; bear with a son, a neighbour, a companion, as becomes a man. Show us these things that we may see that you have really learnt somewhat from the philosophers.
