384-322 BCE
-384 – -322Aristotle
Ancient Greek philosopher and polymath who systematized knowledge across logic, ethics, politics, biology, and metaphysics.
About Aristotle
Born in Stagira, trained at Plato's Academy for twenty years, then tutor to the young Alexander who would conquer the world, Aristotle became perhaps history's most influential thinker. He invented formal logic, founded biology as a science (dissecting over 500 species), wrote the foundational texts of ethics, politics, physics, metaphysics, rhetoric, and poetics. Where Plato looked to abstract Forms, Aristotle looked at the world before him: the oak tree, the city-state, the human being striving for flourishing (eudaimonia). His golden mean taught that virtue lies between extremes; his four causes showed how to truly explain anything. For two millennia, to study philosophy meant to study Aristotle.

Example conversation with Aristotle
Topic: The Golden Mean and Practical Wisdom
You
How does the golden mean actually work? Is it just about being moderate in everything?Aristotle
Not at all, and this is a common misunderstanding. The mean is not arithmetic moderation but the right response for the right situation. Consider courage: it is the mean between cowardice and recklessness. But what counts as courageous depends on who you are, what you face, and what is at stake. A soldier and a physician require different forms of courage. The mean is relative to the person and the circumstance, which is precisely why virtue requires practical wisdom, phronesis, not merely a formula one applies mechanically.You
So how do you actually develop this practical wisdom? It sounds like it takes a lifetime.Aristotle
It does take time, and that is why I insist that virtue is a hexis, a stable disposition formed through repeated practice. You become courageous by doing courageous things, just as you become a skilled builder by building. But practice alone is insufficient. You must also deliberate well about your ends, observe those who exhibit excellence, and reflect on your own actions honestly. The young can be brilliant in mathematics, but practical wisdom requires experience of life. One must have lived through enough situations to recognize the relevant features of new ones.You
What about situations where there is no obvious middle ground? What if all the options seem extreme?Aristotle
Then you must attend carefully to the particular circumstances, for the mean is not always equidistant from the extremes. Sometimes you must lean toward one side to correct a tendency in yourself or in the situation. If you are naturally timid, you must deliberately practice acts that others might consider bold. I also teach that some actions admit of no mean at all: murder, theft, and cruelty are wrong absolutely, not matters of degree. The person of practical wisdom perceives these distinctions, and this perception, trained through habit and reflection, is itself the standard by which we judge.Key ideas
- •Virtue as a mean between extremes (golden mean)
- •Four causes: material, formal, efficient, final
- •Phronesis (practical wisdom) as the bridge from knowledge to action
- •Syllogistic logic and systematic classification
- •Teleology: understanding things in terms of their ends (telos)
How to apply
- •Explain systems with the four causes before optimizing them
- •Use taxonomy-first thinking to clarify messy domains
- •Cultivate habits that move behavior toward virtuous means
- •Balance universal principles with context via practical wisdom
