Consciousness, knowledge, and truth

Scholars from all the continents have written articles to celebrate the seventieth birthday of Jan Srzednicki, a thinker still at the height of his powers. Born in Warsaw on 24 April 1993, Jan Srzednicki divided his energies between his philosophical studies at the University of Warsaw and his service in the underground army. In 1944 he was caught up in the dramatic attempt to liberate Warsaw from the Nazis. Srzednicki's scientific work alternates between problems of Austrian and German philosophy and questions of political philosophy. The papers published in this volume discuss topics of general philosophy, in the clear and deep style both of Srzednicki's own philosophical work and of the Authors investigated in his writings (mainly Brentano and the Polish tradition of analytic philosophy). The topics developed pertain to the fields of epistemology (common sense, knowledge and objectivity, truth and perception) and of logic and philosophy of logic (paraconsistent logic, definition and duality).
