  Antiochus, who was active in the latter part of the second and the early part of the first centuries B.C.E., was a member of the Academy, Plato’s school, during its skeptical phase. After espousing skepticism himself, he became a dogmatist. He defended an epistemological theory essentially the same as the Stoics’ and an ethical theory which synthesized elements from the Stoa and Plato and Aristotle. In both areas he claimed to be reviving the doctrines of the Old Academy of Plato and his earliest successors and Aristotle.
