One man is naturally prone to avarice, another is the slave of wine, a third of lust; or, if not yet enslaved by these passions, he is so fashioned by nature that this is the direction in which his character would probably lead him. Therefore, to return to my original proposition, every bad man is ungrateful, because he has the seeds of every villainy in him; but he alone is rightly so called who is naturally inclined to this vice. Upon such a person as this, therefore, I shall not bestow a benefit. One who betrothed his daughter to an ill-tempered man from whom many women had sought a divorce, would be held to have neglected her interests; a man would be thought a bad father if he entrusted the care of his patrimony to one who had lost his own family estate, and it would be the act of a madman to make a will naming as the guardian of one’s son a man who had already defrauded other wards. So will that man be said to bestow benefits as badly as possible, who chooses ungrateful persons, in whose hands they will perish.
