Aristotle first used the term Ethics to name a field of study developed by his predecessors Socrates and Plato. In philosophy, Ethics is the attempt to offer a rational response to the question of how humans should best live. Aristotle regarded Ethics and Politics as 2 related but separate fields of study, since Ethics examines the good of the individual, while Politics of the Polis.

Metaphysics (τὰ μετὰ τὰ φυσικά, "things after the ones about the natural world"; Latin: Metaphysica) is one of the principal works of Aristotle, in which Aristotle develops the doctrine that he refers to sometimes as Wisdom, sometimes as First Philosophy, and sometimes as Theology. It is one of the first major works of the branch of western philosophy known as Metaphysics.

Politics (Πολιτικά) is a work of political philosophy by Aristotle, a 4th-century BC Greek philosopher. The title of Politics literally means "the things concerning the πόλις : Polis", and is the origin of the modern English word politics. Aristotle's Politics is divided into 8 books, which are each further divided into chapters. Aristotle distinguishes 3 Good Constitutions: Royalty, Aristocracy and Constitutional Government.
