Stanisław Leśniewski (1886-1939) was one of the most influential and prominent Polish logicians of the twentieth century, and a co-founder of the Warsaw School of Logic. He is best known for the creation of a unique system of the foundations of mathematics comprising three deductive theories: Protothetic, Ontology, and Mereology.

Despite Leśniewski's notable contributions to logic and the foundations of mathematics, he only managed to publish a few hundred pages, leaving a substantial portion of his work unpublished at the time of his death. Unfortunately, in 1944, all of his unpublished manuscripts were lost in the fire of bombed Warsaw.

The roots of Protothetic can already be found in Leśniewski's early research conducted between 1912 and 1914. The `deductions' that can be found in his 1916 work on the general theory of sets are based on his logical intuitions which eventually were captured in the axioms and directives of Protothetic and Ontology. In 1921, having developed his systems of Mereology and Ontology, Leśniewski was ready to search for a general system `of first principles', which he named Protothetic.

This volume is a collection of the major contributions to Protothetic. The title Leśniewski's Systems: Protothetic does not imply that all relevant papers on Protothetic are included, as some were omitted due to similarity or volume constraints. Also excluded are Leśniewski's own papers dealing with Protothetic, as they are already republished in Stanisław Leśniewski: Collected Works, 1992.
