Abstract

The paper focuses on the stoic doctrine of knowing, highlighting the nature of the stoik phantasy, which had been understood as an impression and later as a change of the tension of the main part of the soul . The stoic phantasies are devided according to their origin and epistemological meanaing into sense and non-sense ones and into cataleptical and non-cataleptical ones. In stoic epistemology a clear definition of a catleptic phantasy is very important, because for the Stoics it embodies a means for grasping the lecta, it is therefore the citerion of the true knowledge
