Greek philosopher and scientist, Aristotle, lived in the 4th century B.C. and is regarded as one of the most important figures of classical antiquity. Aristotle was probably the most famous member of Plato's Academy in Athens, whose writings would ultimately form the first comprehensive system of Western philosophy. His writings were not constrained to simply one field of inquiry but covered such various subjects as physics, biology, metaphysics, logic, ethics, aesthetics, rhetoric, linguistics, politics, and government. Contained in this volume is Aristotle's "Metaphysics", one of the most important philosophical treatises of all time. In this highly influential work, Aristotle explores the fundamental nature of existence, humanity's perception of it through both the senses and human reason, and the various static and transitory qualities of reality. A reconciliation of the metaphysical theories which came before him, including Plato's "Theory of Forms" and the contrasting theories of Heraclitus and Parmenides, Aristotle's "Metaphysics" is a work which seeks to answer some of the most fundamental of philosophical questions; what is existence, how does it undergo change, and how do we as humans come to understand it?
