This work presents a complete and informative overview of Nicholas Reschers philosphy. A prominent representative of contemporary pragmatism and of the twentieth centurys intellectual history, Rescher has written an impressive amount of volumes and essays on a wide variety of philosophical topics. The present book attempts to make his theses and theories accessible in one single volume. Moreover, it provides an apparatus of references to the relevant literature produced by Reschers critics, and positions his work in the wider setting of its links with various contemporary American and European philosophers. The mixture of pragmatism and idealism typical of Reschers stance is carefully taken into account, along with his contributions to logic, philosophy of science, metaphysics, theory of knowledge, ethics, social and political philosophy.
