Major Writings

Aristotle wrote an estimated 200 works, most in the form of notes and manuscript drafts. They consist of dialogues, records of scientific observations and systematic works.
Aristotle’s major writings on logic include Categories, On Interpretation, Prior Analytics and Posterior Analytics. In them, he discusses his system for reasoning and for developing sound arguments.

Aristotle’s written work also discussed the topics of matter and form. In his book Metaphysics, he clarified the distinction between the two. To Aristotle, matter was the physical substance of things, while form was the unique nature of a thing that gave it its identity.

In Politics, Aristotle examined human behavior in the context of society and government.
