ANTIOCHUS OF ASCALON (1st century, B.c.), Greek philosopher who attempted to reconcile the doctrines of his teachers Philo of Larissa and Mnesarchus the Stoic. Against the scepticism of Philo, he held that the intellect has in itself a sufficient test of truth; against Mnesarchus, that happiness, though its main factor is virtue, depends also on outward circum stances. This electicism is known as the Fifth Academy (see ACADEMY, GREEK). His writings are lost, and we owe our in formation to Cicero (Acad. Pr., ii. 43) , and Sextus Empiricus (Pyrrh. hyp., i. 235). Antiochus lectured also in Rome and Alexandria.
