Real and Personal Rights.—In different systems of legal nomenclature the term “right” has different meanings, some writers applying it in a restricted, and others in a wider, sense. I shall use it in its wider sense as including “personal rights,” “proprietary rights,” “powers,” “liberties,” “licences,” and so on. The precise meaning of these various kinds of right need not be discussed here, because all legal rights can be broadly divided into two main classes—“personal rights” and “real rights.” As reference will occasionally be made to this broad distinction, a brief explanation of its character is necessary. According to Gloag and Henderson, the difference between real rights and personal rights is correlative to the distinction between duties and obligations. Thus, if I have the full proprietary right in a certain article, including possession and use, this is called a Real Right; and I can make the demand against men in general, or “the world at large,” that my possession and use should not be interfered with. The world at large owes me the Duty of non-interference. I may, however, lend my property to someone for a stated period; and at the end of this period I have the right that he in particular should perform the specific act of returning my property to me. Here it is said that I have a Personal Right against him, and that he has an Obligation to perform this specific act.
