Book 6.8

Some men may receive benefits without knowing it, but no man can bestow them without knowing it. Many sick persons have been cured by chance circumstances, which do not therefore become specific remedies; as, for instance, one man was restored to health by falling into a river during very cold weather, as another was set free from a quartan fever by means of a flogging, because the sudden terror turned his attention into a new channel, so that the dangerous hours passed unnoticed. Yet none of these are remedies, even though they may have been successful; and in like manner some men do us good, though they are unwilling--indeed, because they are unwilling to do so--yet we need not feel grateful to them as though we had received a benefit from them, because fortune has changed the evil which they intended into good. Do you suppose that I am indebted to a man who strikes my enemy with a blow which he aimed at me, who would have injured me had he not missed his mark? It often happens that by openly perjuring himself a man makes even trustworthy witnesses disbelieved, and renders his intended victim an object of compassion, as though he were being ruined by a conspiracy. Some have been saved by the very power which was exerted to crush them, and judges who would have condemned a man by law, have refused to condemn him by favour. Yet they did not confer a benefit upon the accused, although they rendered him a service, because we must consider at what the dart was aimed, not what it hits, and a benefit is distinguished from an injury not by its result, but by the spirit in which it was meant. By contradicting himself, by irritating the judge by his arrogance, or by rashly allowing his whole case to depend upon the testimony of one witness, my opponent may have saved my cause. I do not consider whether his mistakes benefited me or not, for he wished me ill.
