Book 6.9

In order that I may be grateful, I must wish to do what my benefactor must have wished in order that he might bestow a benefit. Can anything be more unjust than to bear a grudge against a person who may have trodden upon one's foot in a crowd, or splashed one, or pushed one the way which one did not wish to go? Yet it was by his act that we were injured, and we only refrain from complaining of him, because he did not know what he was doing. The same reason makes it possible for men to do us good without conferring benefits upon us, or to harm us without doing us wrong, because it is intention which distinguishes our friends from our enemies. How many have been saved from service in the army by sickness! Some men have been saved from sharing the fall of their house, by being brought up upon their recognizances to a court of law by their enemies; some have been saved by ship-wreck from falling into the hands of pirates; yet we do not feel grateful to such things, because chance has no feeling of the service it renders, nor are we grateful to our enemy, though his lawsuit, while it harassed and detained us, still saved our lives. Nothing can be a benefit which does not proceed from good will, and which is not meant as such by the giver. If any one does me a service, without knowing it, I am under no obligation to him; should he do so, meaning to injure me, I shall imitate his conduct.
