Stoic physicsStoic physics refers to the natural philosophy of the Stoic philosophers of ancient Greece and Rome which they used to explain the natural processes at work in the universe. To the Stoics, the cosmos is a single pantheistic god, one which is rational and creative, and which is the basis of everything which exists. Nothing incorporeal exists. The nature of the world is one of unceasing change, driven by the active part or reason (logos) of God which pervades all things.
Platonic AcademyThe Academy (Akademía) was founded by Plato in 387 BC in Athens. Aristotle studied there for twenty years (367–347 BC) before founding his own school, the Lyceum. The Academy persisted throughout the Hellenistic period as a skeptical school, until coming to an end after the death of Philo of Larissa in 83 BC. The Platonic Academy was destroyed by the Roman dictator Sulla in 86 BC. The Akademia was a school outside the city walls of ancient Athens.
Religious skepticismReligious skepticism is a type of skepticism relating to religion. Religious skeptics question religious authority and are not necessarily anti-religious but skeptical of specific or all religious beliefs and/or practices. Socrates was one of the most prominent and first religious skeptics of whom there are records; he questioned the legitimacy of the beliefs of his time in the existence of the Greek gods.
PyrrhonismPyrrhonism is an Ancient Greek school of philosophical skepticism which rejects dogma and advocates the suspension of judgement over the truth of all beliefs. It was founded by Aenesidemus in the first century BCE, and said to have been inspired by the teachings of Pyrrho and Timon of Phlius in the fourth century BCE. Pyrrhonism is best known today through the surviving works of Sextus Empiricus, writing in the late second century or early third century CE.
Middle PlatonismMiddle Platonism is the modern name given to a stage in the development of Platonic philosophy, lasting from about 90 BC – when Antiochus of Ascalon rejected the scepticism of the new Academy – until the development of neoplatonism under Plotinus in the 3rd century. Middle Platonism absorbed many doctrines from the rival Peripatetic and Stoic schools. The pre-eminent philosopher in this period, Plutarch (c. 45–120), defended the freedom of the will and the immortality of the soul.
PyrrhoPyrrho of Elis (ˈpɪroʊ; Pyrrhо̄n ho Ēleios; 360-270 BC), born in Elis, Greece, was a Greek philosopher of Classical antiquity, credited as being the first Greek skeptic philosopher and founder of Pyrrhonism. Pyrrho of Elis is estimated to have lived from around 365/360 until 275/270 BCE. Pyrrho was from Elis, on the Ionian Sea. He was likely a member of the Klytidiai, a clan of seers in Elis who interpreted the oracles of the Temple of Zeus at Olympia where Pyrrho served as a high priest.
EpistemeIn philosophy, episteme (epistēmē; épistémè) is knowledge or understanding. The term epistemology (the branch of philosophy concerning knowledge) is derived from episteme. Plato, following Xenophanes, contrasts episteme with doxa: common belief or opinion. The term episteme is also distinguished from techne: a craft or applied practice. In the Protagoras, Plato's Socrates notes that nous and episteme are prerequisites for prudence (phronesis).
EclecticismEclecticism is a conceptual approach that does not hold rigidly to a single paradigm or set of assumptions, but instead draws upon multiple theories, styles, or ideas to gain complementary insights into a subject, or applies different theories in particular cases. However, this is often without conventions or rules dictating how or which theories were combined. It can sometimes seem inelegant or lacking in simplicity, and eclectics are sometimes criticized for lack of consistency in their thinking.
AenesidemusAenesidemus (Αἰνησίδημος or Αἰνεσίδημος) was a 1st-century BC Greek Pyrrhonist philosopher from Knossos who revived the doctrines of Pyrrho and introduced ten skeptical "modes" (tropai) for the suspension of judgment. He broke with the Academic Skepticism that was predominant in his time, synthesizing the teachings of Heraclitus and Timon of Phlius with philosophical skepticism. Although his primary work, the Pyrrhonian Discourses, has been lost, an outline of the work survives from the later Byzantine empire, and the description of the modes has been preserved by few ancient sources.
AtaraxiaIn Ancient Greek philosophy, ataraxia (Greek: ἀταραξία, from "a-", negation and tarachē "disturbance, trouble")—generally translated as "unperturbedness", "imperturbability", "equanimity", or "tranquility"—is a lucid state of robust equanimity characterized by ongoing freedom from distress and worry. In non-philosophical usage, ataraxia was the ideal mental state for soldiers entering battle. Achieving ataraxia is a common goal for Pyrrhonism, Epicureanism, and Stoicism, but the role and value of ataraxia within each philosophy varies in accordance with their philosophical theories.
