Philosophy

During the Hellenistic period, many different schools of thought developed, and these schools of Hellenistic philosophy had a significant influence on the Greek and Roman ruling elite.

Athens, with its multiple philosophical schools, continued to remain the center of philosophical thought. However, Athens had now lost her political freedom, and Hellenistic philosophy is a reflection of this new difficult period. In this political climate, Hellenistic philosophers went in search of goals such as ataraxia (un-disturbedness), autarky (self-sufficiency), and apatheia (freedom from suffering), which would allow them to wrest well-being or eudaimonia out of the most difficult turns of fortune. This occupation with the inner life, with personal inner liberty and with the pursuit of eudaimonia is what all Hellenistic philosophical schools have in common.

The Epicureans and the Cynics eschewed public offices and civic service, which amounted to a rejection of the polis itself, the defining institution of the Greek world. Epicurus promoted atomism and an asceticism based on freedom from pain as its ultimate goal. The Cyrenaics and Epicureans embraced hedonism, arguing that pleasure was the only true good. Cynics such as Diogenes of Sinope rejected all material possessions and social conventions (nomos) as unnatural and useless. Stoicism, founded by Zeno of Citium, taught that virtue was sufficient for eudaimonia as it would allow one to live in accordance with Nature or Logos. The philosophical schools of Aristotle (the Peripatetics of the Lyceum) and Plato (Platonism at the Academy) also remained influential. Against these dogmatic schools of philosophy the Pyrrhonist school embraced philosophical skepticism, and, starting with Arcesilaus, Plato's Academy also embraced skepticism in the form of Academic Skepticism.

The spread of Christianity throughout the Roman world, followed by the spread of Islam, ushered in the end of Hellenistic philosophy and the beginnings of Medieval philosophy (often forcefully, as under Justinian I), which was dominated by the three Abrahamic traditions: Jewish philosophy, Christian philosophy, and early Islamic philosophy. In spite of this shift, Hellenistic philosophy continued to influence these three religious traditions and the Renaissance thought which followed them.
