The Greek word philosophy means “the love of wisdom”. Ancient Greek philosophy was the ancient Greeks’ attempt to make sense out of the world, in a non-religious way. So rather than using myths to understand the world, they used their intelligence and reasoning skills. Philosophy gained prominence in the 6th century BC and continued throughout the Hellenistic period when Alexnader the Great spread the Greek ideals and culture in most of the known world of his time.
Greek philosophers, such as Plato and Aristotle, dealt with a wide variety of subjects, including political philosophy, ethics, metaphysics, ontology, logic, biology, rhetoric, and aesthetics.
It’s widely accepted by most modern philosophers and historians that Greek philosophy has influenced much of Western culture since its inception.
As stated by the philosopher Martin Litchfield West “Greek philosophers taught themselves to reason. Philosophy as we understand it is a Greek creation“.
Western philosophic tradition was so influenced by Socrates (as presented by his student Plato, and also by Xenophon) that it is conventional to refer to philosophy developed prior to Socrates as pre-Socratic philosophy. The periods following this until the wars of Alexander the Great are those of “classical Greek” and “Hellenistic” philosophy.
