Abstract

One challenge of societies in the 21st century is the conflict of norms between different cultures. In Ancient Greece, too, such conflicts arose, and great thinkers offered great solutions. In this contribution we will argue for the following: - Ancient ethical theories were not only individual ethical theories but also social ethical theories (II). - The ancient methods of scientific examinations are useful not only in classical sciences but also in ethics (III). - Accepting the result of (III) yields highly interesting theoretical results about conflicts of norms between different cultures (IV).
