These things of which we spoke are not benefits, but they possess the appearance of benefits. “Then, just as they are quasi-benefits, so your man is quasi-ungrateful, not really ungrateful.” This is untrue, because both he who gives and he who receives them speaks of them as benefits; so he who fails to return the semblance of a real benefit is as much an ungrateful man as he who mixes a sleeping draught, believing it to be poison, is a poisoner.
