Abstract
The problem of justice lies at the heart of the philosophy of jurisprudence. Then what justice does, the purpose for which a legal system exists, the central principle of jurisprudence, is to provide, for concrete cases, a basis for decisions as to what is just. In the lecture I will first of all deal with Kant's ideas about justice, as shown in his works. They can also be seen as examples of a concept of justice from a previous epoch. The magnitude of these distances will become apparent when one bears in mind what Kant meant, and in what context, when he used this concept. At the same time Kant is the thinker who is most often mentioned in the contemporary discourse on justice. This is for two reasons. Firstly, Kant's position is exemplary for that position that holds that justice is the trancendental centre of any theory of jurisprudence; secondly, Kant is seen as the most significant thinker of that epoch, which is seen as the starting point for the present: the modern European Enlightenment. Finally I would like to contrast the concept of justice which has been developed in this way with the concept that seems fitting for the concrete situation of the Istanbul Congress of 2003.
