The article exposes and analyzes Michel Foucault’s ideas on ethics. He embarked on this particular analysis by surveying classical Greece, in order to discover some pointers in doing ethics for today. He called it aesthetics of existence, as the ancient Greeks patterned their individual existence based on what they believe as the way towards attaining a beautiful life. The two important principles that were dominant then were care of the self (epimeleia heauton) and know yourself (gnothi heauton). Through his genealogy, it became clear that the ancient people puts more accentuation on the know yourself principle, which lead to what he calls as history’s wrong turning. He meant to look back in ancient period so that the modern subjects can have a glimpse of a possible paradigm they can adopt, which is to have a new ethics. Foucault would have that modern subjects also consider rapport a soi (the self’s relation to itself) as an important component a subject should assume to have a veritable ethical dimension. Finally, Foucault argues that there is a new way of doing ethics which is more in congruence to the situation of the contemporary subject.
