Abstract
In my analysis I deal with some causes and origins of evil and of moral degeneration in the human dimension. My analysis focuses on Plato’s Republic. The origins and causes of the presence of injustice and of vice lie in the very structure of the human soul. The division of the soul into parts which are at least reciprocally independent of each other implies that there is the possibility that they are in conflict with each other. This is the origin of injustice and the root of every form of evil. The correct equilibrium among the parts of the soul, which, in my opinion, are to be interpreted as authentic potencies, can be achieved only by developing the rational part. This development requires a thorough education in philosophy. Throughout my analysis I quote passages in which Plato points out the presence of bad instincts and, in general, of a morally difficult component in our soul. The kind of soul considered in my analysis is the embodied soul.
