Aristotle’s ideas of Being and Change, of elements and compounds and of the structure of the universe had an overwhelming influence, even upon those, such as the Stoics and the Neoplatonists, who did not belong to his school of thought. In the Middle Ages all scholastic sects accepted his cosmology; later the vast majority of Renaissance philosophers, even though they were more inclined towards Platonism, would accept much of his natural philosophy and most of his astronomical system.
