Abstract

The paper tries to represent the polemic between the Stoics and the sceptically oriented Academy, concerning the abilities of human knowledge. It gives a brief account of the stoic epistemology on the basis of the characteristics of its criterion of knowledge – cataleptic fantasy. The description of the external and internal features of the latter is the ground of its criticism from Academy’s side.
