Aristotle (; Greek: Ἀριστοτέλης Aristotélēs, pronounced [aristotélɛːs]; 384–322 BC) was a Greek philosopher during the Classical period in Ancient Greece, the founder of the Lyceum and the Peripatetic school of philosophy and Aristotelian tradition. Along with his teacher Plato, he has been called the "Father of Western Philosophy". His writings cover many subjects – including physics, biology, zoology, metaphysics, logic, ethics, aesthetics, poetry, theatre, music, rhetoric, psychology, linguistics, economics, politics and government. Aristotle provided a complex synthesis of the various philosophies existing prior to him, and it was above all from his teachings that the West inherited its intellectual lexicon, as well as problems and methods of inquiry. As a result, his philosophy has exerted a unique influence on almost every form of knowledge in the West and it continues to be a subject of contemporary philosophical discussion.

Nonviolence is not some exalted regimen that can be practiced only by a monk or a master; it also pertains to the way one interacts with a child, vacuums a carpet, or waits in line. . . . Whenever we separate ourselves from a given situation (for example, through inattentiveness, negative judgments, or impatience), we "kill" something valuable: . . . people, things, one's own composure, the moment itself. . . . These small-scale incidences of violence accumulate relentlessly, are multiplied on a social level, and become a source of the large-scale violence that can sweep down upon us so suddenly. . . . One need not wait until war is declared and bullets are flying to work for peace. . . . A more constant and equally urgent battle must be waged each day against the forces of one's own anger, carelessness, and self-absorption.
