Anecdotes

Aristotle was the tutor of the young Alexander of Macedon, the future Alexander the Great, for approximately three years beginning in 343 BC. King Philip II entrusted him with his son's education at the sanctuary of the Nymphs, in Mieza. This teacher-student relationship is one of the most celebrated in history.

Aristotle had a habit of teaching while walking along the shaded paths of the Lyceum, his school in Athens. His students thus came to be known as the "Peripatetics", from the Greek peripatein meaning "to walk". This pedagogical method has remained associated with his name.

Upon the death of Alexander the Great in 323 BC, anti-Macedonian sentiment spread through Athens. Aristotle, regarded as close to the Macedonians, was accused of impiety. He chose to flee to Chalcis, declaring that he did not wish Athens to "sin twice against philosophy", alluding to the condemnation of Socrates.

Aristotle was a passionate observer of nature. He dissected marine animals on the island of Lesbos and produced anatomical descriptions of remarkable precision for his time. Some of his observations on cephalopods were not confirmed by modern science until centuries later.

After the death of his first wife Pythias, niece of his patron Hermias, Aristotle lived with Herpyllis, originally from Stagira. In his will, he expressly requested that Pythias's bones be placed beside his own, testifying to a deep attachment.

Primary Sources

Nicomachean Ethics (vers 340 av. J.-C.)
Happiness is an activity of the soul in accordance with virtue, and if there are several virtues, in accordance with the best and most complete among them.
Politics (vers 330 av. J.-C.)
Man is by nature a political animal. He who lives outside the city, naturally and not by chance, is either a degraded being or a superhuman one.
Metaphysics (vers 340 av. J.-C.)
All men by nature desire to know. The pleasure we take in the perceptions of our senses is proof of this.
Poetics (vers 335 av. J.-C.)
Tragedy is the imitation of a noble action, carried through to its end and having a certain magnitude, by means of language embellished with various kinds of ornament. It operates through pity and fear to bring about the purgation of these emotions.
History of Animals (vers 343 av. J.-C.)
We must, without reluctance, approach the study of every animal, for in each there is something natural and beautiful.
