Overview

The Peripatetic School is the philosophical community that began when Aristotle established the Lyceum in Athens in 335 BCE. Its members investigated subjects ranging from logic and metaphysics to ethics, politics, and biology. After an early decline, a text-centered Aristotelian commentary tradition revived in the first century BCE and culminated around 200 CE with Alexander of Aphrodisias, the last major ancient commentator committed strictly to Aristotelian philosophy.

Key ideas

  • Four Causes: To explain anything fully requires identifying its material, formal, efficient, and final causes — what it's made of, its structure, what produced it, and its purpose.
  • Hylomorphism: Aristotle analyzes perceptible substances as compounds of matter (hyle) and form (morphe), locating their forms in the substances themselves.
  • Eudaimonia and Virtue: The good life consists in flourishing (eudaimonia), achieved by developing virtues — stable dispositions to act in accordance with reason, hitting the mean between extremes.
  • Formal Logic: Aristotle's logical works contain the earliest surviving formal study of logic. Their account of syllogistic deduction shaped later ancient, Arabic, and Latin logical traditions.

Methods used

Positions held

Influenced by

  • Platonism

    Aristotle trained in Plato's Academy for about twenty years, and Platonic questions and methods remained a major point of departure even where his own school rejected Plato's answers.

Reacts to

  • Platonism

    Aristotle's rejection of separately existing Forms — locating form in the particular substance rather than a transcendent realm — is his defining departure from his teacher.

Later connections

  • Averroism Influenced by this tradition

    Siger of Brabant and Boethius of Dacia developed Aristotle's philosophy on its own terms even where it contradicted Christian teaching; Boethius held that Aristotelian natural science must deny that the world had a beginning.

  • Medieval Islamic Philosophy Influenced by this tradition

    Once the whole of Aristotle's corpus had been translated into Arabic, al-Farabi and Avicenna read it as one system of demonstrative science crowned by the Metaphysics, and Alexander of Aphrodisias's treatises shaped their cosmology and their account of the intellect.

  • Medieval Jewish Philosophy Influenced by this tradition

    Maimonides used Aristotelian logic and metaphysics to reinterpret Scripture, reconciling revelation with demonstrative reason in the Guide of the Perplexed.

  • Scholasticism Influenced by this tradition

    The twelfth- and thirteenth-century Latin recovery of Aristotle's works gave the schools the framework they worked in — hylomorphism, the four causes, and demonstration from prior premises — and theological questions were then posed in those terms.

  • Virtue Ethics Revival Renewed this tradition after a break

    Anscombe's 1958 essay called for a return to Aristotle's ethical vocabulary — the virtues, practical wisdom (phronesis), and eudaimonia as flourishing — and Foot, MacIntyre and Hursthouse then rebuilt a full normative theory on those concepts.

  • Neoplatonism Incorporated this tradition into a synthesis

    Plotinus made Aristotle's self-thinking divine intellect the model for Nous, the second level of reality, and used the matter-and-form analysis throughout, while denying that the first principle could be an intellect at all.
