The author made an attempt to recreate the psychology, theory of knowledge and logical teaching of the Ancient Stoa in the context of the entire worldview of the school. Particular attention is paid to the process of formation of the categorical world and the system of terms within which this world was formed. The study is based on the author's own translations. A separate section contains the author's translations of fragments of the Early and Middle Stoas related to moral issues.
