The aim of the paper is to shed light on the concept of cataleptic phantasy, which in Stoic fhiilosophy has been the kriterion of true knowledge. On the basis of original texts of Stoic fragments the author points out specific subjective and objective symptoms of its cataleptical chracter, distinguishing at the same time strictly between sensory ane non-sensory kind of Stoic 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 menaning that makes it possible. Thus the author inclines clearly to the rationalist interpretation of Stoic epistemology, which, contrary to sensualistic approaches, puts the stress on the importance of non-sensory cataleptic phantasy as the kriterion of true knowledge in Stoic Philosophy.
