Cataleptic phantasy in Stoic epistemology

The aim of the paper is to shed light on the concept of cataleptic phantasy , which in Stoic philosophy has been the criterion of true knowledge. On th e basis of original texts of Stoic fragments the author points out the spec ific subjective and objective symptoms of its cataleptic character, disting uishing the same time strictly between sensory and non-sensory kind of Stoi c phantasies. The author shows, that the way from a cataleptic phantasy to a cognitive content is not a straightforward one and that it is the logical meaning that makes it possible. Thus, the author inclines clearly to the r ationalist interpretation of Stoic epistemology, which, contrary to sensual approaches, puts the stress on the importance of non-sensory cataleptic ph antasy as the criterion of true knowledge in Stoic philosophy.
