Which philosopher is known for teaching Alexander the Great?

The philosopher known for teaching Alexander the Great is Aristotle. As a student of Plato, Aristotle founded his own school, the Lyceum, where he developed his philosophical ideas and conducted extensive research. His influence extended beyond philosophy into various fields, including science, ethics, and politics.

When Aristotle began tutoring Alexander at a young age, he imparted not only academic knowledge but also lessons in ethics and leadership. This mentorship significantly shaped Alexander's thinking and character, which later influenced his approach to governance and conquest. Aristotle's teachings emphasized the importance of virtue and rationality, which likely contributed to Alexander's strategies and behaviors as a leader.

In contrast, while Plato, Socrates, and Epicurus were highly influential philosophers, their direct interactions with Alexander or specific teachings that shaped his development do not hold the same relevance as Aristotle's role as his tutor. Therefore, Aristotle's direct mentorship and philosophical guidance to Alexander position him as the correct answer to this question.
