This is plainly the principle acted upon in Political Communities: he receives no honour who gives no good to the common stock: for the property of the Public is given to him who does good to the Public, and honour is the property of the Public; it is not possible both to make money out of the Public and receive honour likewise; because no one will put up with the less in every respect: so to him who suffers loss as regards money they award honour, but money to him who can be paid by gifts: since, as has been stated before, the observing due proportion equalises and preserves Friendship.
Like rules then should be observed in the intercourse of friends who are unequal; and to him who advantages another in respect of money, or goodness, that other should repay honour, making requital according to his power; because Friendship requires what is possible, not what is strictly due, this being not possible in all cases, as in the honours paid to the gods and to parents: no man could ever make the due return in these cases, and so he is thought to be a good man who pays respect according to his ability.
For this reason it may be judged never to be allowable for a son to disown his father, whereas a father may his son: because he that owes is bound to pay; now a son can never, by anything he has done, fully requite the benefits first conferred on him by his father, and so is always a debtor. But they to whom anything is owed may cast off their debtors: therefore the father may his son. But at the same time it must perhaps be admitted, that it seems no father ever would sever himself utterly from a son, except in a case of exceeding depravity: because, independently of the natural Friendship, it is like human nature not to put away from one’s self the assistance which a son might render. But to the son, if depraved, assisting his father is a thing to be avoided, or at least one which he will not be very anxious to do; most men being willing enough to receive kindness, but averse to doing it as unprofitable.
