Aristotle

384–322 BCE

Plato's student, who systematised logic and wrote on nearly every field of knowledge, from biology and physics to ethics, politics and metaphysics.

Man is naturally a political animal.

Politics 1253a, translated by William Ellis

Born in Stagira in northern Greece, Aristotle studied at Plato’s Academy and later founded his own school, the Lyceum. Unlike Plato, he located the forms of things within the things themselves, and he placed great weight on careful observation. His logic remained the standard for two thousand years, and his ethics — centred on virtue and human flourishing (eudaimonia) — is still widely studied.

His work was transmitted to the medieval world largely through Arabic philosophers, who called him simply “the First Teacher”.

Key ideas

The first logic
Aristotle was the first to set out the rules of valid reasoning systematically. His theory of deduction, known today as syllogistic, came with a logic of the possible and the necessary.
The four causes
To explain something fully we must give four causes, the “because”s behind it. These are what it’s made of (the bronze of a statue), its form, what brought it about (the sculptor) and its end, the purpose it serves.
Form and matter
Ordinary objects such as houses, horses and humans are composites of matter and form. This answers Parmenides’ challenge to the reality of change: whenever something changes, one thing stays while another is acquired or lost.
Happiness as flourishing (eudaimonia)
The highest human good is eudaimonia, achieved by fully realising our nature and developing our human capacities to the highest degree. It consists in living by reason, and is not a matter of personal taste.
Political animals
Human beings are by nature political animals, who can flourish only within an organised city (polis). The city “comes into being for the sake of living, but it remains in existence for the sake of living well”.
