ENThe article tries to discern what historical structures of morality are investigated in Foucault's genealogy. It concludes that in every historical culture he discerns the same repeating structural contours of morality. He sees a connection between power games and the relation towards oneself (rapport ą soi) in Greek, Roman and Christian cultures. The article concludes that acording to Foucault's books his interest in ancient morality cannot be identified with his own ethical views. He does not look for a universal ground for morality in the ethics of antiqity. This historical theatre of changes in ethics, reconstructed by Foucault, was only to see the possibility of thinking about ourselves in a different manner than we do today. But the subject of Foucault's ethics is always rooted in historical situations.
