The question of the motivation of the individual's pursuit of mature self fulfillment can best be analyzed in terms of the phenomenon that has tradition ally been called askesis. We should be aware that this phenomenon is basic to human development and is not limited to religious applications. Thus Marshall McLuhan speaks of literacy as "an abstract asceticism that prepares the way for endless patterns of privation in the human community."1 The idea of privation for the sake of attaining bodily excellence, prizes, or fame is, of course, the basis for the training program (askesis) of the athlete. More complex goals sometimes involve a collective asceticism. Thus our technical culture, like the monastic culture of the Middle Ages, presumes a vast heritage of behavioral conditioning in which punctuality, teamwork, postponement of rewards, mechanical apti tudes, and discipline are all essential parts.2 Individual and collective ascesis both require that something that is itself relatively good be sacrificed for the sake of something considered more valuable. For example, the beauty of the creative work of the individual artist-craftsman, something quite definitely good in itself, has had to be sacrificed to a great extent in the course of the development of industrial society.3 The idea of ascetical practice is usually connected with projects of a long-term nature involving goals that are intended to give man a sense of having realized a higher form of human existence. The philosopher is defined by the goal in life that he has assigned to himself, namely, the pursuit of wisdom. The Greeks put great value on the attainment of kalos kagathos, the great and worthy man; Epictetus spoke of the "freedom of the sage who acts without hindrance in choice"; the Orphies and Pythagoreans chose ritual purification, while the Cynic-Stoic popular tradition opted for detachment in a search for a more human existence. Ascesis as a religious experience has been characterized by strict methodology and often minutely regulated practices involving much austerity, self-denial, and even self-infliction of pain.4
