Abstract

We propose a comparison between Descartes' and Cicero's Ethics. Both started from the doubt, but the first one left the moral philosophy under the doubt while the other projected it to the excellence. We underline that Cicero's book On the Duties contains -even nowadays- a program for the youth: leadership, social commitment and courage. And we add that Cicero's ethics lean on the wise man example: the one who dares to remain alone
