 The most influential account of respect for persons is found in the moral philosophy of Immanuel Kant (1785, 1788, 1793, 1797). Indeed, most contemporary discussions of respect for persons explicitly claim to rely on, develop, or challenge some aspect of Kant’s ethics. Central to Kant’s ethical theory is the claim that all persons, regardless of personal qualities or achievements, social position, or moral track-record, are owed respect just because they are persons, that is, beings with rational and autonomous wills. To be a person is to have a status and worth unlike that of any other kind of being: it is to be an end in itself with dignity. And the only appropriate response to such a being is respect. Moreover, respect for persons is not only appropriate but also unconditionally required: persons must always be respected. Because we are all too often inclined not to respect each other, one formulation of the Categorical Imperative, which is the supreme principle of morality, commands that our actions express due respect for persons: “Act in such a way that you treat humanity, whether in your own person or the person of any other, never simply as a means but always at the same time as an end” (Grundlegung zur Metaphysik der Sitten (Groundwork of the Metaphysics of Morals) (1785, 4:429). Although commentators disagree about how precisely to understand this imperative, one common view is that it defines our fundamental moral obligation as respect all persons, including ourselves, and thus defines morally right actions as those that express respect for persons as ends in themselves and morally wrong actions as those that express disrespect or contempt for persons (Wood 1999). (On other readings, respect is one of our fundamental duties, but there are others, such as love, justice, and moral self-improvement.) In addition to this general commandment, Kant argues that there are also more specific duties of respect for other persons and self-respect, to which we’ll return. For now, we must address the question, What is it to be an end in itself and to possess dignity?
