Excellence is an art won by training and habituation. We do not act rightly because we have virtue or excellence, but we rather have those because we have acted rightly. We are what we repeatedly do. Excellence, then, is not an act but a habit. Aristotle
Together with Plato and Socrates (Plato's teacher), Aristotle (384 BC – 322 BC) 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. We will meet him from time to time, for example when we think about the need to classify ideas and concepts.
