Which famous ancient Greek philosopher taught Alexander the Great?

Alexander the Great was famously tutored by Aristotle, one of the most significant figures in Western philosophy. Aristotle, a student of Plato, had a profound impact on various fields, including ethics, politics, metaphysics, and natural sciences. His teachings emphasized the importance of empirical observation and logic, which greatly influenced Alexander's approach to leadership and governance.

Under Aristotle's mentorship, Alexander developed critical thinking skills and a deep appreciation for knowledge and culture, which he carried with him throughout his conquests. This relationship between teacher and student is significant in history, highlighting how Aristotle's philosophies shaped the worldview of one of history's most renowned military leaders. In contrast, Socrates and Plato were influential philosophers in their own right but did not directly teach Alexander. Hippocrates, though a key figure in medicine, was not associated with Alexander's philosophical education. Thus, the correct answer identifies the tutor who had the most direct influence on Alexander's intellectual development.
