## TL;DR

Greek philosophy is often introduced through Socrates, Plato, and Aristotle, but the field also includes Presocratic thinkers and Hellenistic schools such as Stoicism, Epicureanism, and Skepticism.

## Core Explanation

Socrates is known indirectly, mostly through later writers. Plato developed philosophical dialogues that made Socrates central to questions about knowledge, ethics, politics, and metaphysics. Aristotle, who studied in Plato's Academy, developed systematic inquiries across logic, biology, ethics, politics, rhetoric, and natural philosophy.

## Evidence Notes

This article now uses the Stanford Encyclopedia of Philosophy for the core biographical and disciplinary claims. It avoids unsupported claims such as calling Plato's Academy the first Western university.
