Modern Polish philosophy has an impressive record as a powerful, innovating tradition, in many respects parallel to but independent of the development of analytical philosophy in Britain and America. Owing to an absence of adequate translations however, the work of its leading exponents has generally only been encountered second-hand. To remedy this, Quinton and Skolimowski have translated an introduction to philosophy written by Kazimierz Ajdukiewicz, probably the outstanding representative of the generation. Problems and Theories of Philosophy surveys concisely and, so far as possible, systematically the main problems in epistemology and metaphysics and the most historically important of the solutions proposed to them. The book still reads freshly and displays many of the characteristic intellectual virtues of Polish philosophy: clarity and straightforwardness of presentation combined with a bracing rigour and precision. It is in no sense parochial to its Polish origins and can stand beside the classic English introductions to the subject as stimulating and lucid analysis of perennial philosophical problems and strategies.
