Abstract

Author discusses the possibility of thought experiment to produce a priori knowledge. Author analyzes some arguments which come from the critics of a priori. In this paper he examines the ontological and epistemological role of thought experiment in natural science and humanities. Author claims that the concept of 'apriorism' should be considered as a crucial point for classical understanding of cognition, especially within the empiricism and rationalism tradition. However, nowadays 'apriorism' loses its epistemological meaning within some modern epistemological traditions.
