Abstract:In order to get out of modern individual emotional and ethical dilemmas,Macintyre advocates the restoration of the Aristotelianism tradition of virtual ethics.His efforts are certainly failure.Machiavelli at the beginning of the modern time revived the classical virtual tradition of republicanism which has provided us with a new option out of modern ethical dilemma.He established the basic ethical principles of communitarianism that the community is priority to the individual and the public goodness priority to the private goodness,highlighted the country’s public instrument,and demonstrated individual participation in community life by virtues,the importance for sustainable community.However,the virtual community of classical republicanism is not the best community,has nothing to do with the soul perfect,there is a moral debt in it,and needs to constantly improve itself.
