Abstract
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.
