Bernard Bolzano, who was born in Prague in 1781 and died there in 1848, was the greatest logician between Leibniz and Frege, universally renowned for his theories of logical truth, inference and reasoning. He was a creative mathematician, but also a Catholic priest who was convinced that his church was in need of reform, an astute analyst of moral and political concepts and a political dissident. In his magisterial study, his opus magnum, Wolfgang Künne describes Bolzano's life and afterlife in the context of Czech history between Joseph II and Václav Havel. He introduces the reader to Bolzano's contemporary friends and enemies and to his rediscoverers, who were pupils or grand-pupils of Bolzano or Czech mathematicians. And he presents Bolzano's most important writings in the order in which they were written and comments on them in detail.
