Stanislaw Lesniewski 1886 – 1939
Stanislaw Lesniewski (1886 – 1939) was a Polish philosopher of the Contemporary era, associated with Analytic Philosophy.
Stanislaw Lesniewski was a Polish logician, philosopher of mathematics, and the most uncompromising formalist of the Lwow-Warsaw school. After studies under Kazimierz Twardowski at Lwow and a doctorate under Hans Cornelius at Munich, he held the chair of the philosophy of mathematics at Warsaw, where he developed his three interrelated formal systems: Mereology, the logic of parts and wholes; Ontology, his general theory of names and predication; and Protothetic, a comprehensive logic of propositions and quantifiers. The extreme rigor of his standards meant that much of his work survives only through his pupils, above all Alfred Tarski.
