The Lvov-Warsaw School and the Idea of Unification of Scientific Knowledge

Abstract

The article is divided into three parts. The first section contains explications of the concept of unity of science, of the concept of reduction, and of their mutual relation. These conceptual investigations are presented against the background of the Vienna Circle’s programme. The second part presents the criticism of the idea of unity of science in the Lvov-Warsaw School, mostly in the works of Kazimierz Ajdukiewicz and Maria Kokoszyńska. The third part concerns various proposals of reduction which appeared in the Lvov-Warsaw School.
