You are doubtless aware that the constitution of this republic is one which answers the great test proposed by Tom Paine, who imagined it to be of the essence of a free constitution that it should be capable of being _put into the pocket_! That splendid capability was never more fully realised by the laws of a sixpenny club, than by the great charter of American liberties. It is a thing written on paper, and may be thrust into the breeches, or hung up on the wall, as best suits the notions of its worshipper, and his manner of exhibiting respect. Now the law of copyright is not here, as you suppose, a mere matter of statute; nor is the doctrine that an author has no perpetual property in what his intellect creates, a simple decision of courts. It is a part of the constitution, which empowers the national Congress "to promote the progress of science and useful arts, by securing _for limited times_, to authors and inventors, the exclusive right to their respective writings and discoveries." An American writer has remarked, that its equivalent would have been the concession of a power to _promote_ the fisheries, by allowing to fishermen a _limited number_ of the cod-fish and herrings which they take on a Newfoundland fog-bank. Here then, you will say, is a fundamental obstruction to literary justice in America! But your hasty conclusion will show that you have thought but little on written constitutions. I agree with the Count de Maistre, that such instruments are of all things the most slippery. What is easier than for Congress to evade its restriction, and make the _limited time_ exactly the years of Methusaleh! Such a limit would be about as good as "to one's heirs for ever." But there is yet another facility in written constitutions: "a breath unmakes them, as a breath has made." In America, a constitution is as easily overhauled, new-ribbed, and launched again, as ever a sloop-of-war was dry-docked and new-coppered. Here, for instance, is the great "Empire State" of New York, with a constitution hardly a year old! The stripling who has just attained his majority, has actually survived the whole life of its predecessor; and he who lives half as long again, will see the new one superannuated and going the way of all written constitutions. The late constitution of this State was in many respects a noble one; but its successor plays the mischief with every thing; and I have heard an old freeholder complain that he hardly knows whether he has a house, a wife, or a head on his shoulders; so radically has the revolution affected whatever is social and civil. This will show you that there is, after all, no necessary perpetuity in the present condition of things; and so I come to the statute, which is the only just cause of complaint.
