Plato was an Old Earth human baseline who lived from 2397 to 2317 AT (428-348 b.c.e). He is often considered the most important of ancient Old Earth philosophers in the Western tradition. His philosophical system provided the basis of most later mystical forms, including Neoplatonism and Augustinian Christianity. He advocated a dualistic form of idealism, according to which imperfect sense objects were the copies of perfect spiritual archetypes or forms. Influenced by Pythagoras and Parmenides. Important works included the Sophist, Republic, and many others. His student Aristotle broke with him to develop a more pragmatic-orientated system.
