71. Now, this being one of the most complete and special ways of wasting money,--no money being less productive of good, or of any percentage whatever, than that which we shake away from the ends of undertakers' plumes,--it is of course the duty of all good economists, and kind persons, to prove and proclaim continually, to the poor as well as the rich, that respect for the dead is not really shown by laying great stones on them to tell us where they are laid; but by remembering where they are laid, without a stone to help us; trusting them to the sacred grass and saddened flowers; and still more, that respect and love are shown to them, not by great monuments to them which we build with _our_ hands, but by letting the monuments stand, which they built with _their own_. And this is the point now in question. 72. Observe, there are two great reciprocal duties concerning industry, constantly to be exchanged between the living and the dead. We, as we live and work, are to be always thinking of those who are to come after us; that what we do may be serviceable, as far as we can make it so, to them, as well as to us. Then, when we die, it is the duty of those who come after us to accept this work of ours with thanks and remembrance, not thrusting it aside or tearing it down the moment they think they have no use for it. And each generation will only be happy or powerful to the pitch that it ought to be, in fulfilling these two duties to the Past and the Future. Its own work will never be rightly done, even for itself--never good, or noble, or pleasurable to its own eyes--if it does not prepare it also for the eyes of generations yet to come. And its own possessions will never be enough for it, and its own wisdom never enough for it, unless it avails itself gratefully and tenderly of the treasures and the wisdom bequeathed to it by its ancestors.
