Marcus Aurelius (121-180) was the Roman
emporor who as a Stoic philosopher endowed
chairs in Athens for the four great
philosophical schools of the Academy, the
Lyceum, The Garden and the Stoa. Aurelius'
Stoicism, tempered by his frined Fronto's
humanism, held to a rational world-order
and providence as well as to a notion of
probable truth rather than of the Stoic
infallibilism.
