Hellenistic philosophy

Hellenistic philosophy is the period of Western philosophy that was developed in the Hellenistic civilization following Aristotle and ending with the beginning of Neoplatonism.

Hellenistic schools of thought

Pythagoreanism

Pythagoreanism is the name given to the system of philosophy and science developed by Pythagoras, which influenced nearly all the systems of Hellenistic philosophy which followed. Two schools of Pythagorean thought eventually developed, one based largely on mathematics and continuing his line of scientific work, the other focusing on his more esoteric teachings, though each shared a part of the other.

Pythagoras of Croton (570-495 BCE)
Hippasus (5th century BCE)

Sophism

In Ancient Greece, the sophists were a category of teachers who specialized in using the tools of philosophy and rhetoric for the purpose of teaching aretê — excellence, or virtue — predominantly to young statesmen and nobility.

Protagoras (490-420 BCE)
Gorgias (485-380 BCE)
Antiphon (480-411 BCE)

Cynicism

The Cynics were an ascetic sect of philosophers beginning with Antisthenes in the 4th century BC and continuing until the 5th century AD. They believed that one should live a life of Virtue in agreement with Nature. This meant rejecting all conventional desires for wealth, power, health, or fame, and living a life free from possessions.

Antisthenes (445-365 BCE)
Diogenes of Sinope (412-323 BCE)
Crates of Thebes (365-285 BCE)
Menippus (c. 275 BCE)
Demetrius (10-80 CE)

Cyrenaicism

The Cyrenaics were an ultra-hedonist school of philosophy founded in the 4th century BC, by Aristippus of Cyrene. They held that pleasure was the supreme good, especially immediate gratifications. The school was replaced within a century by the more moderate doctrine of Epicureanism.

Aristippus of Cyrene (435-360 BCE)

Platonism

Platonism is the name given to the philosophy of Plato, which was maintained and developed by his followers. The central concept was the Theory of forms: the transcendent, perfect archetypes, of which objects in the everyday world are imperfect copies. The highest form was the Form of the Good, the source of being, which could be known by reason. In the 3rd century BC, Arcesilaus adopted skepticism, which became a central tenet of the school until 90 BC when Antiochus added Stoic elements, rejecting skepticism. With the adoption of oriental mysticism in the 3rd century AD, Platonism evolved into Neoplatonism.

Speusippus (407-339 BCE)
Xenocrates (396-314 BCE)
Arcesilaus (316-232 BCE)
Carneades (214-129 BCE)
Antiochus of Ascalon (130-68 BCE)
Plutarch (46-120 CE)

Peripateticism

The Peripatetics was the name given to the philosophers who maintained and developed the philosophy of Aristotle. They advocated examination of the world to understand the ultimate foundation of things. The goal of life was the happiness which originated from virtuous actions, which consisted in keeping the mean between the two extremes of the too much and the too little.

Aristotle (384-322 BCE)
Theophrastus (371-287 BCE)
Strato of Lampsacus (335-269 BCE)
Alexander of Aphrodisias (c. 200 CE)

Skepticism

Pyrrhonism, or Pyrrhonian skepticism, was a school of skepticism beginning with Pyrrho in the 3rd century BC, and further advanced by Aenesidemus in the 1st century BC. It advocated total philosophical scepticism about the world in order to attain "ataraxia" or a tranquil mind, maintaining that nothing could be proved to be true so we must suspend judgement.

Pyrrho (365-275 BCE)
Timon (320-230 BCE)
Aenesidemus (1st century BCE)
Sextus Empiricus (2nd century CE)

Epicureanism

Epicureanism was founded by Epicurus in the 3rd century BC. It viewed the universe as being ruled by chance, with no interference from gods. It regarded absence of pain as the greatest pleasure, and advocated a simple life. It was the main rival to Stoicism until both philosophies died out in the 3rd century AD.

Epicurus (341-270 BCE)
Metrodorus (331-278 BCE)
Zeno of Sidon (1st century BCE)
Philodemus (110-40 BCE)
Lucretius (99-55 BCE)

Stoicism

Stoicism was founded by Zeno of Citium in the 3rd century BC. Based on the ethical ideas of the Cynics, it taught that the goal of life was to live in accordance with Nature. It advocated the development of self-control and fortitude as a means of overcoming destructive emotions. It was the most successful school of philosophy until it died out in the 3rd century AD.

Zeno of Citium (333-263 BCE)
Cleanthes (331-232 BCE)
Chrysippus (280-207 BCE)
Panaetius (185-110 BCE)
Posidonius (135-51 BCE)
Seneca (4 BCE-65 CE)
Epictetus (55-135 CE)
Marcus Aurelius (121-180 CE)

Eclecticism

Eclecticism was a system of philosophy which adopted no single set of doctrines but selected from existing philosophical beliefs those doctrines that seemed most reasonable. Its most notable advocate was Cicero.

Varro Reatinus (116-27 BCE)
Cicero (106-43 BCE)
Seneca the Younger (4 BCE-65 CE)

Hellenistic Judaism

Hellenistic Judaism was an attempt to establish the Jewish religious tradition within the culture and language of Hellenism. Its principal representative was Philo of Alexandria.

Philo of Alexandria (30 BC-45 CE)
Josephus (37-100 CE)

Neopythagoreanism

Neopythagoreanism was a school of philosophy reviving Pythagorean doctrines, which was prominent in the 1st and 2nd centuries CE. It was an attempt to introduce a religious element into Greek philosophy, worshipping God by living an ascetic life, ignoring bodily pleasures and all sensuous impulses, to purify the soul.

Nigidius Figulus (98-45 BCE)
Apollonius of Tyana (40-120 CE)
Numenius of Apamea (2nd century CE)

Hellenistic Christianity

Hellenistic Christianity was the attempt to reconcile Christianity with Greek philosophy, beginning in the late 2nd century. Drawing particularly on Platonism and the newly emerging Neoplatonism, figures such as Clement of Alexandria sought to provide Christianity with a philosophical framework.

Clement of Alexandria (150-215 CE)
Origen (185-254 CE)
Augustine of Hippo (354-430 CE)

Neoplatonism

Neoplatonism, or Plotinism, was a school of religious and mystical philosophy founded by Plotinus in the 3rd century AD and based on the teachings of Plato and the other Platonists. The summit of existence was the One or the Good, the source of all things. In virtue and meditation the soul had the power to elevate itself to attain union with the One, the true function of human beings. It was the main rival to Christianity until dying out in the 6th century.
