Aristotle (
Greek:
Ἀριστοτέλης,
Aristotélēs) (384 BC – 322 BC) was a
Greek philosopher, a student of
Plato and teacher of
Alexander the Great. His writings cover many subjects, including
physics,
metaphysics,
poetry, theater, music, logic, rhetoric, politics, government, ethics, biology, and zoology. Together with Plato and
Socrates (Plato's teacher), Aristotle is one of the most important founding figures in Western philosophy. Aristotle's writings were the first to create a comprehensive system of Western philosophy, encompassing morality and aesthetics, logic and science, politics and metaphysics.
Aristotle's views on the
physical sciences profoundly shaped medieval scholarship, and their influence extended well into the
Renaissance, although they were ultimately replaced by
Newtonian physics. In the zoological sciences, some of his observations were confirmed to be accurate only in the nineteenth century. His works contain the earliest known formal study of logic, which was incorporated in the late nineteenth century into modern
formal logic. In metaphysics,
Aristotelianism had a profound influence on
philosophical and theological thinking in the Islamic and Jewish traditions in the
Middle Ages, and it continues to influence
Christian theology, especially
Eastern Orthodox theology, and the
scholastic tradition of the
Catholic Church. His ethics, though always influential, gained renewed interest with the modern advent of
virtue ethics. All aspects of Aristotle's philosophy continue to be the object of active academic study today. Though Aristotle wrote many elegant treatises and dialogues (
Cicero described his literary style as "a river of gold"),
[1] it is thought that the majority of his writings are now lost and only about one-third of the original works have survived.
[2] Despite the far-reaching appeal that Aristotle's works have traditionally enjoyed, today modern scholarship questions a substantial portion of the Aristotelian corpus as authentically Aristotle's own.
