Twardowski, Kazimierz (1866–1938)

Twardowski, one of the most distinguished of Brentano’s students, became famous for his distinction between the content and object of presentations. Twardowski, after his appointment as a professor of philosophy at the University of Lwów (Lvov), considerably limited his own philosophical research for the sake of teaching activities. He set himself an ambitious task: to create a scientific philosophy in Poland. Twardowski fully realized his aim, giving the first step towards the so-called Lwów–Warsaw School, a group of philosophers working in analytic philosophy – in particular, logic, philosophy of science, and philosophy of language. In spite of his concentration on teaching, Twardowski also made remarkable contributions to philosophy after coming to Lwów.
