The place of physical education has been contested in recent times and it has been argued that its justification as part of school curricula seems to be marginal at best. Such justifications as have been offered, propose that physical education is justified because of its contribution to moral development or because it is capable of being studied as a theoretical subject. Other justifications have centred on the embodied nature of the human being. In this article we draw on some classical thinkers, Plato, Aristotle, Aquinas, Augustine and Benedict, to argue for a strong, integrated view of the human person. From this it is concluded that physical education is a necessary component of education and that a complete education therefore involves physical education. Physical education is understood in a broad sense as a family resemblance concept which incorporates a wide variety of physical activities. Disciplined physical activity which enables individuals to gain those physical skills required for learning, it is proposed, is essential for intellectual development. Benedictine education, which involves hard physical work, reading, prayer and reflection, illustrates how the physical and mental aspects of a person are to be integrated in order to attain the ends of the committed Benedictine monk.
