If we were to live here always, with no other care than how to feed, clothe, and house ourselves, life would be a very sorry business. It is immeasurably heightened by the solemnity of death. The brutes die even as we; but it is our knowledge that we have to die that makes us human. If nature cunningly hides death, and so permits us to play out our little games, it is easily seen that our knowing it to be inevitable, that to every one of us it will come one day or another, is a wonderful spur to action. We really do work while it is called to-day, because the night cometh when no man can work. We may not expect it soon--it may not have sent us a single _avant-courier_--yet we all know that every day brings it nearer. On the supposition that we were to live here always, there would be little inducement to exertion. But, having some work at heart, the knowledge that we may be, any day, finally interrupted, is an incentive to diligence. We naturally desire to have it completed, or at least far advanced toward completion, before that final interruption takes place. And knowing that his existence here is limited, a man's workings have reference to others rather than to himself, and thereby into his nature comes a new influx of nobility. If a man plants a tree, he knows that other hands than his will gather the fruit; and when he plants it, he thinks quite as much of those other hands as of his own. Thus to the poet there is the dearer life after life; and posterity's single laurel leaf is valued more than a multitude of contemporary bays. Even the man immersed in money-making does not make money so much for himself as for those who may come after him. Riches in noble natures have a double sweetness. The possessor enjoys his wealth, and he heightens that enjoyment by the imaginative entrance into the pleasure which his son or his nephew may derive from it when he is away, or the high uses to which he may turn it. Seeing that we have no perpetual lease of life and its adjuncts, we do not live for ourselves. And thus it is that death, which we are accustomed to consider an evil, really acts for us the friendliest part, and takes away the commonplace of existence. My life, and your life, flowing on thus day by day, is a vapid enough piece of business; but when we think that it must _close_, a multitude of considerations, not connected with ourselves but with others, rush in, and vapidity vanishes at once. Life, if it were to flow on forever and _thus_, would stagnate and rot. The hopes, and fears, and regrets, which move and trouble it, keep it fresh and healthy, as the sea is kept alive by the trouble of its tides. In a tolerably comfortable world, where death is not, it is difficult to see from what quarter these healthful fears, regrets, and hopes could come. As it is, there are agitations and sufferings in our lots enough; but we must remember that it is on account of these sufferings and agitations that we become
