Aristotelianism
Aristotelianism is the long wager that the world is intelligible through the things it is for: forms in matter, causes in order, virtues in balance, and minds trained to follow nature’s purposes rather than fear its complexity.

Timeline
Birth of Aristotle
**384 BC** — Aristotle was born in Stagira, a city on the Macedonian fringe of the Greek world. His later philosophy would combine outsider attentiveness with the training of the Athenian intellectual center.
Aristotle Joins Plato’s Academy
**367 BC** — Aristotle entered the Academy in Athens and remained there for roughly two decades. The experience placed him inside Plato’s philosophical inheritance while setting up the divergences that would define his mature work.
Composition of Core Biological and Metaphysical Works
**350 BC** — During and after his years of independent inquiry, Aristotle developed the lines of thought that appear in works such as the Physics, De Anima, and Parts of Animals. These texts show the emergence of his explanatory scheme of form, matter, and purpose.
Founding of the Lyceum
**345 BC** — After leaving the Academy, Aristotle established his own school in Athens, the Lyceum. There the study of constitutions, animals, logic, and ethics became part of a shared research program.
Nicomachean Ethics and the Doctrine of Eudaimonia
**340 BC** — In the ethical writings, Aristotle articulated the idea that human flourishing depends on virtuous activity over a complete life. The account of virtue as a mean relative to us became one of the most influential formulations in moral philosophy.
Politics and the Human Being as a Political Animal
**330 BC** — Aristotle’s political theory argued that the polis exists by nature and that human beings are political animals. The work tied civic life to the possibility of virtue and the good life, not merely to survival or contract.
Death of Aristotle
**322 BC** — Aristotle died in 322 BCE after leaving Athens amid political turbulence. His school survived him, and the question became how his systematic inquiry would be preserved and interpreted.
Alexander of Aphrodisias Systematizes Aristotelian Commentary
**00200** — In late antiquity, Alexander of Aphrodisias produced influential commentaries that treated Aristotle as the authoritative interpreter of nature and intellect. His work helped define what it meant to read Aristotle seriously as a system.
Birth of Averroes
**1126** — Ibn Rushd was born in Cordoba and would become one of the most important Aristotelian interpreters in the Islamic world. His commentaries would reshape the transmission of Aristotle into Latin scholasticism.
Aquinas Completes the Great Scholastic Synthesis
**1274** — Thomas Aquinas died in 1274 after having integrated Aristotelian concepts into Christian theology at the highest level. His work became the classic example of Aristotelianism transformed rather than merely preserved.
Birth of Galileo Galilei
**1564** — Galileo’s work on motion and astronomy challenged the physical assumptions of the Aristotelian cosmos. His success marked the beginning of a long reorganization of natural philosophy away from classical teleology.
Aristotelian Natural Philosophy Gives Way to the Mechanical Philosophy
**1642** — By the time of Galileo’s death, the scientific revolution had decisively shifted the explanatory center of gravity. Aristotelianism remained influential in ethics, metaphysics, and theology, but not as the dominant physics of nature.
