The Dignity of Persons

Kant’s profound idea that every human being has an intrinsic, inviolable worth - a dignity beyond all price - which became the philosophical foundation of modern human rights.

From the lesson

Kant drew one of the most profound distinctions in the history of ethics: between things that have a price and beings that have a dignity. A thing has a price if it can be exchanged for, or replaced by, something else of equivalent value - if it has a value relative to something else, for which it can be traded. But a being has a dignity if it has an intrinsic, unconditional, incomparable worth - a worth that is above all price, that admits of no equivalent, that cannot be exchanged or replaced. And rational beings - persons - have, Kant argued, not a price but a dignity: an intrinsic, unconditional, incomparable worth, above all price, that must always be respected. Persons are not things to be valued by their price, used and exchanged; they have a dignity - an intrinsic, priceless, inviolable worth - that sets them above all price and demands respect. This distinction - between the price of things and the dignity of persons - is one of the most profound and influential in the history of ethics.

A profound and revolutionary implication of Kant’s idea of dignity is that all persons have equal dignity - that every human being, simply in virtue of their rational, autonomous, moral nature, has the same intrinsic, inviolable worth, regardless of their wealth, status, achievements, race, sex, or any other contingent feature. The dignity of persons, grounded in their shared rational, autonomous, moral nature, belongs to every person equally - for every person is a rational, autonomous, moral being, an end in itself, with the same intrinsic worth. No person has more or less dignity than another based on wealth, status, achievement, race, sex, or any contingent feature; all persons have equal dignity, simply as rational, autonomous, moral beings. This equal dignity of all persons - the radical idea that every human being, regardless of any contingent feature, has the same intrinsic, inviolable worth - is one of the most profound and revolutionary moral ideas in history. It grounds the moral equality of all persons, the equal worth and equal claim to respect of every human being, against all hierarchies and discriminations based on contingent features. The equal dignity of all persons, grounded in their shared rational nature, is one of the foundations of modern morality, human rights, and the moral equality of all human beings.

Kant’s idea of human dignity - the intrinsic, inviolable, equal worth of every person - became the philosophical foundation of modern human rights. The modern conception of human rights - the rights every person has simply as a human being, which must be respected and protected - rests largely on the idea of human dignity that Kant articulated. The Universal Declaration of Human Rights (1948), the foundational document of modern human rights, opens by affirming ‘the inherent dignity… of all members of the human family’ as the foundation of human rights - grounding human rights in the inherent dignity of every person, in language that echoes Kant. The modern human rights tradition rests on the Kantian idea that every person has an intrinsic, inviolable, equal dignity that must be respected, and that this dignity grounds the rights every person has simply as a human being. Kant’s idea of human dignity - the intrinsic, inviolable, equal worth of every person, grounded in their rational, autonomous, moral nature - thus became the philosophical foundation of the modern human rights tradition, one of the great moral achievements of the modern world. The idea that every human being has an inherent dignity that grounds inviolable rights - central to modern morality, law, and human rights - derives largely from Kant, and is perhaps his greatest and most consequential contribution to the moral life of humanity.

This is the opening of the lesson. The rest — the dialogue, the primary source, and the recall — is in the app.

What you'll be able to recall

You learned that Kant grounded human dignity in the intrinsic worth of rational persons, becoming the foundation of human rights. Explain Kant’s idea of dignity and its significance for human rights, in your own words.
