The modern notion of guilt, understood as evaluative conflict (moral) is a psychological historically constructed category. The Greeks of the archaic and classical period lacked the experience of guilt as we feel it now. This paper discuss about the problem of guilt in ancient Greece and about the conditions that made possible his birth and operation. Between these they emphasize the moralization of até it; originally understood as a irrational madness, and transformed in the archaic period in punishment of the gods, and, increasing the gradient of personal freedom to the detriment of the religious powers, which is emerging in the 5th century B.C. in Sophocles and Euripides, and especially in Aristotle in the 4th century B.C. Finally we present a line of interpretation about how historical practices associated of the notion of guilt are crossing the clinic and psychotherapeutic work.
Key words: Guilt, Genealogy of moral, freedom, psychotherapy.
