In books it is easy to make mention of the forgotten dead to whom we are indebted, and to acknowledge an obligation at the same time and place that we incur it. The more original a writer is, the more pleasure will he take in calling attention to the forgotten work of those who have gone before him. The conventions of painting and music, on the other hand, while they admit of borrowing no less freely than literature does, do not admit of acknowledgement; it is impossible to interrupt a piece of music, or paint some words upon a picture to explain that the composer or painter was at such and such a point indebted to such and such a source for his inspiration, but it is not less impossible to avoid occasionally borrowing, or rather taking, for there is no need of euphemism, from earlier work. Where, then, is the line to be drawn between lawful and unlawful adoption of what has been done by others? This question is such a nice one that there are almost as many opinions upon it as there are painters and musicians. To leave painting on one side, if a musician wants some forgotten passage in an earlier writer, is he, knowing where this sleeping beauty lies, to let it sleep on unknown and unenjoyed, or shall he not rather wake it and take it—as likely enough the earlier master did before him—with, or without modification? It may be said this should be done by republishing the original work with its composer’s name, giving him his due laurels. So it should, if the work will bear it; but more commonly times will have so changed that it will not. A composer may want a bar, or bar and a half, out of, say, a dozen pages—he may not want even this much without more or less modification—is he to be told that he must republish the ten or dozen original pages within which the passage he wants lies buried, as the only righteous way of giving it new life? No one should be allowed such dog-in-the-manger-like ownership in beauty that because it has once been revealed to him therefore none for ever after shall enjoy it unless he be their cicerone. If this rule were sanctioned, he who first produced anything beautiful would sign its death warrant for an earlier or later date, or at best would tether that which should forthwith begin putting girdles round the world.
