Augustine argues that Greco-Roman civic virtue is the product of the servile fear in his The City of God, and that their pursuit of glory is simply the mask for the lust for domination. Defining apatheia as a condition that the mind cannot be touched by any emotion, he also shows that apatheia, a good life Greco-Roman philosophy pursuits, is the worst of all vices rather than goodness. The uniqueness of Augustine's account of fear is his usage of clean fear as signifying the act of will by which the citizens of the city of God could necessarily keep away from sin. For him, the servile fear is a just retribution which the first human beings received for their disobedience, while the clean fear, a gift from God and obedience as its essence, will be eternal.
