Euthyphro

Besides being an excellent example of the early, so-called Socratic dialogues, Euthyphro contains several passages with important philosophical implications. These include those in which Socrates speaks of the one Form, presented by all the actions that we call pious (5d), as well as the one in which we are told that the gods love what is pious because it is pious; it is not pious because the gods love it (10d). Another passage clarifies the difference between genus and species (11e–12d).
