Aristotle is synonymous with ancient Greek tradition, and is the foundation on which almost all Western thought is pried upon. A brilliant philosopher, Aristotle authored and framed several discourses on a wide range of subjects from ethics, economics, politics, and logic.
Plato is believed to have mentored Aristotle, and yet, their philosophies are miles apart. Where Plato is vague, Aristotle is vivid, where Plato is an idealist, Aristotle is a rationalist and a realist. This results in a very interesting dichotomy: The liege vs the prodigy, and Idealism vs Realism.
