For a long time Franz Brentano has been widely perceived almost exclusively as the re-discoverer of intentionality and the founder of the continental phenomenology. It was only during the last 30 years that his immense importance for the development of analytic philosophy (and also the arbitrariness of the very division between analytic and continental philosophy) became clear. This volume is devoted to Brentano’s influence on the Polish Analytic Philosophy better known under the name of : “Lvov-Warsaw School”.
