Aristotle was an ancient Greek philosopher whose work has been extremely important to the development of both western philosophy and western theology. It has traditionally been thought that Aristotle started out in agreement with Plato and gradually moved away from his ideas, but recent research suggests just the opposite. Important Books by Aristotle Very little of what we have appears to have been published by Aristotle himself. Instead, we have notes from his school, much of which were created by his students during the time Aristotle taught. Aristotle himself wrote a few works intended for publication, but we only have fragments of these. Major works: CategoriesOrganonPhysicsMetaphysicsNicomachean EthicsPoliticsRhetoricPoetics Famous Quotations by Aristotle “Man is by nature a political animal.”(Politics) “Excellence or virtue is a settled disposition of the mind that determines our choice of actions and emotions and consists essentially in observing the mean relative to us ... a mean between two vices, that which depends on excess and that which depends on defect.”(Nicomachean Ethics) Early Life & Background of Aristotle Aristotle came to Athens as a teenager and studied with Plato for 17 years. After Plato’s death in 347 BCE, he traveled widely and ended up in Macedonia where he served as the private tutor of Alexander the Great. In 335 he returned to Athens and founded his own school, called the Lyceum. He was forced to leave in 323 because the death of Alexander allowed free reign to anti-Macedoninan sentiment and Aristotle was too close to the conqueror to dare stick around. Aristotle and Philosophy In Organon and similar works, Aristotle develops a comprehensive system of logic and reasoning for addressing problems of logic, being and reality. In Physics, Aristotle investigates the nature of causation and, hence, our ability to explain what we see and experience. In Metaphysics (which got its name not from Aristotle, but from a later librarian who needed a title for it and, because it was shelved following Physics, got the name After-Physics), Aristotle engages in a very abstract discussion of being and existence in his attempts to justify his other work on causation, experience, etc. In Nicomachean Ethics, among other works, Aristotle explores the nature of ethical conduct, arguing that an ethical life involves achieving happiness and that happiness is best achieved through rational thought and contemplation. Aristotle also defended the idea that ethical conduct derives from human virtues and that virtues are themselves a product of moderation between extremes. With regards to politics, Aristotle argued that humans are, by nature, political animals. This means that humans are also social animals and that any understanding of human behavior and human needs must include social considerations. He also investigated the merits of various kinds of political systems, describing their different virtues and vices. His classification system of monarchies, oligarchies, tyrannies, democracies and republics is still used today.
