There seems . . . to be in authours a stronger right of property than that by occupancy; a metaphysical right, a right, as it were, of creation, which should from its nature be perpetual; but the consent of nations is against it, and indeed reason and the interests of learning are against it; for were it to be perpetual, no book, however useful, could be universally diffused amongst mankind, should the proprietor take it into his head to restrain its circulation. No book could have the advantage of being edited with notes, however necessary to its elucidation, should the proprietor perversely oppose it. For the general good of the world, therefore, whatever valuable work has once been created by an authour, and issued out by him, should be understood as no longer in his power, but as belonging to the publick; at the same time the authour is entitled to an adequate reward. This he should have by an exclusive right to his work for a considerable number of years.
