In his own life, then, a man is not to expect happiness, only to profit by it gladly when it shall arise; he is on duty here; he knows not how or why, and does not need to know; he knows not for what hire, and must not ask. Somehow or other, though he does not know what goodness is, he must try to be good; somehow or other, though he cannot tell what will do it, he must try to give happiness to others. And no doubt there comes in here a frequent clash of duties. How far is he to make his neighbour happy? How far must he respect that smiling face, so easy to cloud, so hard to brighten again? And how far, on the other side, is he bound to be his brother's keeper and the prophet of his own morality? How far must he resent evil?
The difficulty is that we have little guidance; Christ's sayings on the point being hard to reconcile with each other, and (the most of them) hard to accept. But the truth of his teaching would seem to be this: in our own person and fortune, we should be ready to accept and to pardon all; it is our cheek we are to turn, r coat that we are to give away to the man who has taken our cloak. But when another's face is buffeted, perhaps a little of the lion will become us best. That we are to suffer others to be injured, and stand by, is not conceivable and surely not desirable. Revenge, says Bacon, is a kind of wild justice; its judgments at least are delivered by an insane judge; and in our own quarrel we can see nothing truly and do nothing wisely. But in the quarrel of our neighbour, let us be more bold. One person's happiness is as sacred as another's; when we cannot defend both, let us defend one with a stout heart. It is only in so far as we are doing this, that we have any right to interfere: the defence of B is our only ground of action against A. A has as good a right to go to the devil, as we to go to glory; and neither knows what he does.
The truth is that all these interventions and denunciations and militant mongerings of moral half-truths, though they be sometimes needful, though they are often enjoyable, do yet belong to an inferior grade of duties. Ill-temper and envy and revenge find here an arsenal of pious disguises; this is the playground of inverted lusts. With a little more patience and a little less temper, a gentler and wiser method might be found in almost every case; and the knot that we cut by some fine heady quarrel-scene in private life, or, in public affairs, by some denunciatory act against what we are pleased to call our neighbour's vices, might yet have been unwoven by the hand of sympathy.
