Abstract

Hersz Bad (1869–1942) was Kazimierz Twardowski’s student and belonged to the first generation of the Lvov-Warsaw School members. He specialized in the history of philosophy and led a number of remarkable analyses concerning Kant’s philosophy. At the example of his work one may see, how the methodological postulates of the Lvov Warsaw School were fulfilled at the field of historical philosophical investigations. The goal of the paper is to present Bad’s main achievements and to evaluate their meaning from the point of view of the current state of research of Kant’s philosophy. To be reviewed in detail are Bad’s remarks concerning the scientific status of the so called Kant-Laplace Theory as well as the validity of its name.
