The former "Queen of Science" seems to be lacking both a specific subject and a particular method. Thus the need arises for intra- and metaphilosophical orientation – especially since the way philosophy sees itself stems from various influential schools and traditions whose mutual exchange is not as lively as one might have hoped. This volume of original essays brings together some of the protagonists of different metaphilosophical debates that have so far been led fairly independently of each other. The authors discuss the question of both the possibility and the scope of philosophical knowledge under a variety of aspects, particularly: (1) a priori knowledge and the role of intuitions, (2) transcendental arguments, (3) analytic philosophy and its methods as well as (4) phenomenology and analytic philosophy.
