Abstract

Polish philosopher Kazimierz Ajdukiewicz’s survey of epistemological and metaphysical problems, taken from a positivist orientation, is notable for its brief, clear characterizations of philosophical problems and its well placed, simplified expositions of the theories of Plato, Aristotle, Descartes, Berkeley, Hume, Kant, Hegel, Bergson and Husserl. He focusses on the logical limitations of the solutions for clearly defined problems. Any lack of depth in this book is compensated for by the accurate outlines which encourage the reader to question the foundations of classical positions. In the first part of the book, the theory of truth is given logical priority to epistemology. We "... should define truth as agreement of thought with final and irrevocable criteria," to avoid the contradiction of extreme skepticism which could not be formulated without, at least, tacit reference to "reality." Because of this positive but stipulative orientation, a priorism in epistemology is given a thorough exposition. Realism, "... we can know reality only on the basis of experience," is proposed to balance the abstractness of a priorism.
