Human dignity is one of the key concepts of our ethical evaluations, in politics, in biomedicine, as well as in everyday life. In moral philosophy, however, human dignity is a source of intractable trouble. It has a number of characteristic features which apparently do not fit into one coherent ethical concept. Hence, philosophers tend to ignore or circumvent the concept. There is hope for a philosophically attractive conception of human dignity, however, given that one takes three crucial turns. The negative (...) turn: to start the inquiry with violations of human dignity. The inductive turn: to consider the whole range of applications of the concept of human dignity in different areas of ethics. And finally, the historical turn: to take into account the historical bonds between human dignity and traditional conceptions of dignity. Taken together they point in the direction of an understanding of human dignity as universal nobility. (shrink)

This article concerns the morality of establishing regulated kidney markets in an effort to reduce the chronic shortage of kidneys for transplant. The article tries to rebut the view, recently defended by James Taylor, that if we hold autonomy to be intrinsically valuable, then we should be in favor of such markets. The article then argues that, under current conditions, the buying and selling of organs in regulated markets would sometimes violate two Kantian principles that are seen as moral constraints. (...) One principle forbids expressing disrespect for the dignity of humanity; the other forbids treating others merely as means. In light of the moral danger posed by regulated markets, the article advocates an alternative way of diminishing the current organ shortage, namely opt-out systems of cadaveric organ donation.
