Remember, my dear hearers, who are thus thinking, that political economy, like every other subject, cannot be dealt with effectively if we try to solve two questions at a time instead of one. It is one question, how to get plenty of a thing; and another, whether plenty of it will be good for us. Consider these two matters separately; never confuse yourself by interweaving one with the other. It is one question, how to treat your fields so as to get a good harvest; another, whether you wish to have a good harvest, or would rather like to keep up the price of corn. It is one question, how to graft your trees so as to grow most apples; and quite another, whether having such a heap of apples in the store-room will not make them all rot.
Now, therefore, that we are talking only about grafting and growing, pray do not vex yourselves with thinking what you are to do with the pippins. It may be desirable for us to have much art, or little--we will examine that by and by; but just now, let us keep to the simple consideration how to get plenty of good art if we want it. Perhaps it might be just as well that a man of moderate income should be able to possess a good picture, as that any work of real merit should cost £500 or £1,000; at all events, it is certainly one of the branches of political economy to ascertain how, if we like, we can get things in quantities--plenty of corn, plenty of wine, plenty of gold, or plenty of pictures.
It has just been said, that the first great secret is to produce work that will last. Now, the conditions of work lasting are twofold: it must not only be in materials that will last, but it must be itself of a quality that will last--it must be good enough to bear the test of time. If it is not good, we shall tire of it quickly, and throw it aside--we shall have no pleasure in the accumulation of it. So that the first question of a good art-economist respecting any work is, Will it lose its flavour by keeping? It may be very amusing now, and look much like a work of genius. But what will be its value a hundred years hence?
You cannot always ascertain this. You may get what you fancy to be work of the best quality, and yet find to your astonishment that it won't keep. But of one thing you may be sure, that art which is produced hastily will also perish hastily; and that what is cheapest to you now, is likely to be dearest in the end.
