The proposed research project studies two motifs which play a very important role in contemporary philosophy and are inextricably bound up with one another. The first motif is 'the end of metaphysics' in post-Hegelian philosophies of the history of philosophy and philosophies of history in general. The second motif is the self-perception and self-definition of several important post-Hegelian philosophers or philosophical tendencies as post-metaphysical. The first motif contains the idea that metaphysics, as a way of thinking, is not the product of a permanent 'metaphysical need', but that it is a definite phase in the development of humanity, andt that this phase has come to an end, or has to come to an end. The second motif complements and modifies the first one. It contains the idea that metaphysical thinking, as the 'hard core' of Western philosophical tradition up to and including Hegel, is inextricably bound up with the use of several fundamental strategies of thought. These strategies have become irreversibly problematic, and therefore must be at any cost avoided by means of new forms of thought that replace metaphysics.
