The English word "philosophy" comes from the Greek word φιλοσοφία, meaning "love of wisdom", probably coined by Pythagoras. Along with the word itself, the discipline of philosophy as we know it today has its roots in ancient Greek thought, and according to Martin West "philosophy as we understand it is a Greek creation". Ancient philosophy was traditionally divided into three branches: logic, physics, and ethics. However, not all of the works of ancient philosophers fit neatly into one of these three branches. For instance, Aristotle's "Rhetoric" and "Poetics" have been traditionally classified in the West as "ethics", but in the Arabic world were grouped with logic; in reality, they do not fit neatly into either category.
