Pre-Socratic Greek philosophy

Greek philosophy arose and was established in the sixth century BC and continued during the Hellenistic period, and covered a wide range of topics, including political philosophy, ethics, metaphysics, ontology, logic, biology, rhetoric, and aesthetics. Many philosophers today have acknowledged that "Western philosophy is nothing but a series of Plato's notes." Greek philosophy, in the history of Western philosophy, represents the first moment in the development of philosophical thought. From a chronological perspective, this stage is defined as the period starting from the seventh century BC until the end of the Athenian Academy in 529 AD according to the Justinian decree.
