Plato’s writings were in the form of dialogues, usually between Socrates and one or more interlocutors. In one of these dialogues, Euthyphro, there is a discussion concerning whether “right” can be defined as “that which the gods command.” Socrates is skeptical and asks: Is conduct right because the gods command it, or do the gods command it because it is right? It is one of the most famous quotations in the history of philosophy. The contemporary British philosopher Antony Flew suggests that “one good test of a person’s aptitude for philosophy is to discover whether he can grasp its force and point.”
