Read morePlato’s system, as presented through his dialogues and letters, rests on a Parmenidean foundation that requires serious consideration. His critique of Parmenides forms the foundation upon which he constructs his ontology, epistemology, logic, ethics, and aesthetics. Consequently, understanding Plato’s system necessitates an in-depth exploration of his relationship with Parmenides. This study aims to illuminate overlooked aspects in the history of philosophy by examining this relationship, most notably the “possibility of the third state (included middle)” as a principle of logic in Plato’s system. Therefore, the first part of this study focuses on Parmenides, referred to as the “father” in the Sophist, who enabled Plato to establish this principle of logic. The second part reveals how this principle unfolds in the dialogues and how Plato critiques Parmenides to provide a foundation for things that exist “in between.” This study primarily examines the Sophist but also considers Parmenides - Peri Phuseôs, Plato - Parmenides, Symposium, Politeia, and Theaetetus.
