If someone can dispose of something at pleasure in his own name, then that someone has a right to that thing. But if someone can perform only in the name of another, he transacts this business such that the other is thereby bound, as if the business were transacted by himself. (Quod quis facit per alium, ipse fecisse putandus set). Therefore my right to the transacting of a business in the name of another is a personal positive right, to necessitate the author of the business to guarantee something, namely, to answer for everything which he has done through me, or to which he obliges himself through me. The publishing of the work is now a speech to the public (by printing) in the name of the author, and is consequently a business in the name of another. Therefore the right to it is a right of the editor's against a person: not merely to defend himself in the use of his property at pleasure against him; but to necessitate him to acknowledge and to answer for as his own a certain business, which the editor transacts in his name; consequently this is a personal positive right.

The copy, according to which the editor prints, is a work of the author's and belongs totally to the editor after he has purchased it, either in the manuscript form or the printed form, to do with it everything the editor pleases, where said doings can be done in the editor's own name; for that is a requisite of the complete right in a thing, i.e. ownership. But the use, which the editor cannot make of it except only in the name of another (namely the author's), is a business (opera) that this other transacts through the owner of the copy, where in addition to the ownership of the copy, a particular contract is still requisite for other rights to be provided to the owner of the copy.

Now, the publication of a book is a business which can only be transacted in the name of another (namely the author, whom the editor presents as speaking to the public through him); therefore the rights of transacting the business of publishing the book is separate from the rights that are associated with the ownership of a copy of the book. The right to publish the book can legally be acquired only by a particular contract with the author. Who publishes without such a contract with the author (or, if the author has already granted this right to another, i.e. to an authorized editor, without a contract with that authorized editor) is the counterfeiter, who then damages the authorized editor, and must make amends to him for all damages.
