Abstract

According to Plutarch, the theory of psychological disharmony relies on the Platonic music harmony. When Plato refers to music harmony, he means the kind of harmony where the concept of God is the source through which all beings emanate. The mental passions define the quality of human character and consequently develop the social man. As far as the Aristotelian ethical theory is concerned, morality does not condemn the passions, because it has a clear ontological and anthropological basis. The Stoics stress that a trait of the human soul is sociality, and that happens because all human beings are under the law of sympathy and constitute a whole. At medieval times, Boethius portrays the middle age social conditions which also resemble with our postmodern societies.
