"Euthyphro" is a dialogue written by the ancient Greek philosopher Plato. It features a conversation between Socrates and Euthyphro, who is prosecuting his father for murder. The dialogue explores the nature of piety and morality, questioning what it means to be virtuous and how divine approval relates to ethical behavior. Throughout their discussion, Socrates challenges Euthyphro to define piety, leading to a deeper examination of the relationship between the gods and moral values. This philosophical inquiry raises important questions about whether actions are good because the gods approve of them or if the gods approve of them because they are inherently good.
