Aristotle was one of the greatest philosophers of ancient Greece, and one of the greatest minds in human history. Although many of his works were disproved with modern technology, the gaps he made with his limited knowledge of the world at that time shows truly how smart he was. His works cover a many different fields, and the ideas that do not survive today lasted two millennia, until the Renaissance period in the 16th and 17th century.
Aristotle was born in 384 BC to Nicomachus, a physician of Mayntas II of Macedon. He was born in Chalcis, and later moved to Athens in 367 BC. He became a student at Plato's Academy, where he was taught directly by Plato himself, another great mind of ancient Greece. He spent twelve years at the Academy, until the time of Plato's death. He moved around after leaving the Academy, going from Asia Minor, to the Island of Lesbos, to even spending several years with a young Alexander the Great as his personal tutor. .
Aristotle's theories and works included different fields, from logic, philosophy, and ethics to physics, biology, psychology, politics, and rhetoric. The goal of his treatises, known as the Organon, was devolped to create a standard method of philosphy, by which he would be able to understand everthing about reality. He created a system of catagorys which systematicly helped him trying to attain his goal. "Aristotle applied this method, with characteristic emphasis on telogical explaination, to astronomical and biological explorations of the natural world." (Dhawan 1).
One field that Aristotle created that is still studied heavily today is metaphysics. .
Where as physics is the attempt to discover the laws that govern fundamental concrete objects, metaphysics is the attempt to discover the laws that systematize the fundamental abstract objects presupposed by physical science, such as natural numbers, real numbers, functions, sets and properties, physically possible objects and events, to name just a few.
