In 335 BC, Aristotle returned to Athens and established a school at the Lyceum. The investigations associated with him and his students ranged from animal anatomy and political constitutions to logic, ethics, and poetry. The surviving works preserve an extraordinary breadth of inquiry, but also difficult passages, disputed interpretations, and conclusions later readers rejected. His time at Plato’s Academy and his tuition of Alexander place that work within the intellectual and political life of the fourth century BC.
“It is owing to wonder that men both now and at the first began to philosophise.”
384–322 BC
Born in Stagira, a small Greek colony in Chalcidice. Died in exile in Chalcis on the island of Euboea, reportedly saying he would not let Athens sin twice against philosophy — a reference to Socrates's execution seventy-seven years earlier.
20 years
Aristotle remained associated with Plato’s Academy from about age seventeen until Plato’s death in 347 BC. The relationship involved learning, debate, and the development of his own inquiries.
200+
Ancient catalogues list over two hundred treatises. Only about thirty-one survive — mostly lecture notes and working drafts, not the polished dialogues that made him famous in antiquity.
335 BC
The school supported collaborative work across philosophy and natural inquiry. Its research included animal studies, constitutions, and historical records.
Philosopher, scientist, tutor of Alexander the Great, founder of the Lyceum
Defining Events
Tutor to Alexander
Philip II invited Aristotle to educate Alexander during the prince’s early teens. Later accounts emphasize Homer and medicine, but the precise lessons and their influence remain uncertain. Plutarch recounts an annotated Iliad carried on campaign; that later biography should not be treated as a complete record of the tuition.
Founding the Lyceum
Aristotle taught at the public sanctuary of Apollo Lyceus after returning to Athens. The school fostered collaborative inquiry and collected texts, observations, and historical materials. The later name Peripatetic probably came from the walkway, or peripatos, associated with the site.
A System of Logic
Aristotle developed a formal theory of deduction, including categorical and modal syllogisms, in works later grouped as the Organon. Its influence was immense, but logic continued to develop: Stoic philosophers examined propositional arguments, and medieval and modern thinkers expanded the field. A valid inference also requires true premises if its conclusion is to establish knowledge.
Timeline
Born in Stagira
Born in the Greek colony of Stagira in Chalcidice, on the border of Macedonia. His father Nicomachus was court physician to King Amyntas III of Macedon — a connection that would prove decisive decades later when Philip II sought a tutor for his son.
Enters Plato's Academy
At seventeen, Aristotle travels to Athens and enrolls in Plato's Academy, the premier intellectual institution in the Greek world. He would remain there for twenty years — first as student, then as teacher and researcher. Plato reportedly called him 'the reader' and 'the mind of the school.'
Plato Dies; Aristotle Leaves Athens
When Plato dies, leadership of the Academy passes to his nephew Speusippus rather than to Aristotle. Whether Aristotle was passed over or chose to leave is debated. He departs Athens, accepting an invitation from Hermias, ruler of Atarneus and Assos in Asia Minor — a fellow former student of the Academy.
Marine Biology on Lesbos
Aristotle worked with Theophrastus on Lesbos and pursued detailed studies of animals. His biological writings combine observation, dissection, reports from others, and causal arguments. They preserve accurate descriptions alongside errors.
Summoned to Tutor Alexander
Philip II of Macedon invites Aristotle to tutor his thirteen-year-old son Alexander at the sanctuary of Mieza. In return, Philip rebuilds Stagira, which he had previously destroyed, and frees its enslaved inhabitants. Aristotle teaches Alexander for approximately three years.
Founds the Lyceum
Returns to Athens and establishes the Lyceum in a grove sacred to Apollo. The school becomes a centre for empirical research — students collect constitutions of 158 Greek city-states, catalogue animal species, and compile records of dramatic festivals. Aristotle lectures on everything from physics to ethics.
Alexander Dies; Aristotle Flees
When Alexander the Great dies in Babylon, anti-Macedonian sentiment explodes in Athens. Aristotle, closely associated with the Macedonian court, is charged with impiety — the same charge that killed Socrates. He flees to Chalcis, reportedly saying he will not allow Athens to sin twice against philosophy.
Death in Chalcis
Aristotle died on Euboea in 322 BC. His will, preserved by Diogenes Laertius, provides for family members and selected enslaved people, including conditional future freedom for younger servants. It does not record a general rejection of slavery.
Key Figures
Plato
Aristotle spent roughly twenty years at Plato’s Academy. His later criticism of separate Forms developed from problems explored within that intellectual community. The familiar saying about Plato and truth compresses an argument in Nicomachean Ethics I.6; it is not an exact quotation of the surviving passage.
Alexander the Great
Aristotle educated Alexander in his early teens. Later writers emphasized Homer, medicine, and stories of royal support for natural inquiry. The actual scope of their collaboration is uncertain. Callisthenes, Aristotle’s relative and Alexander’s historian, opposed proskynesis and was later arrested in connection with the royal pages’ conspiracy; accounts of his death disagree.
The Legacy of Aristotle
Aristotle’s works traveled through Greek, Syriac, Arabic, Latin, and other traditions, where readers translated, criticized, and transformed them. His influence belongs to that history of interpretation as well as to the inquiries he conducted. Logic, biology, ethics, and political philosophy all owe him much without being reducible to his methods.
The same surviving record contains arguments for slavery and the subordination of women. Their place in his society helps explain them; it does not settle their truth or remove their consequences. This dramatized biography follows a philosopher whose questions remain powerful and whose conclusions remain open to scrutiny.
