“You admit,” says our adversary, “that we sometimes are under no obligation to him from whom we have received a benefit. In that case it has been taken by force.” Nay, there are many things which would cause us to cease to feel gratitude for a benefit, not because the benefit has been taken from me, but because it has been spoiled. Suppose that a man has defended me in a lawsuit, but has forcibly outraged my wife; he has not taken away the benefit which he conferred upon me, but by balancing it with an equivalent wrong, he has set me free from my debt; indeed, if he has injured me more than he had previously benefited me, he not only puts an end to my gratitude, but makes me free to revenge myself upon him, and to complain of him, when the wrong outweighs the benefit; in such a case the benefit is not taken away, but is overcome. Why, are not some fathers so cruel and so wicked that it is right and proper for their sons to turn away from them, and disown them? Yet, pray, have they taken away the life which they gave? No, but their unnatural conduct in later years has destroyed all the gratitude which was due to them for their original benefit.
