If ingratitude were liable to a law, we must never give but before witnesses, which would overthrow the dignity of the benefit: and then the punishment must either be equal where the crimes are unequal, or else it must be unrighteous, so that blood must answer for blood. He that is ungrateful for my saving his life must forfeit his own. And what can be more inhuman than that benefits should conclude in sanguinary events? A man saves my life, and I am ungrateful for it. Shall I be punished in my purse? that is too little; if it be less than the benefit, it is unjust, and it must be capital to be made equal to it. There are, moreover, certain privileges granted to parents, that can never be reduced to a common rule. Their injuries may be cognizable, but not their benefits. The diversity of cases is too large and intricate to be brought within the prospect of a law: so that it is much more equitable to punish none than to punish all alike. What if a man follows a good office with an injury; whether or no shall this quit scores? or who shall compare them, and weigh the one against the other? There is another thing yet which perhaps we do not dream of: not one man upon the face of the earth would escape, and yet every man would expect to be his judge. Once again, we are all of us ungrateful; and the number does not only take away the shame, but gives authority and protection to the wickedness.
