In this symposium, we discuss the intellectual developments in the ancient Greek world that led to the development of the notion of the Logos. We start with mentioning several meanings of the notion of the logos, as well as a discussion of the intellectual transition from the Homeric paradigm to the paradigm of the early Presocratics. Then, we focus on several fragments of Heraclitus where he talks about the Logos. We proceed to discuss the metaphysics of Empedocles and his theory of cosmic cycles. We end the symposium with a brief mention of Polybius, his theory of the anacyclosis of political constitutions, and how it can be seen as influenced by the Presocratics.
