A Review of The Realm of Rights

This book has two purposes: first, to state what it means to have a right; and second, to state which rights human beings have. Because Thomson believes that the first question is prior to the second, she begins by asking why it is morally significant that human beings have rights. Her answer to this question is that rights are a kind of moral constraint such that, other things being equal, one's rights ought to be accorded. As to the second question, Thomson distinguishes rights human beings have qua human beings from rights they have by participating in private transactions or living under a legal system. The former category includes the right not to be killed or harmed; the latter category includes rights related to promise keeping and private property. By explaining what in general makes the attribution of a human or social right true, Thomson seeks to provide a foundation for the notion that the interests of human beings are worthy of respect.
