One of Euthyphro's proposed definitions of to hosion says: '[T]he pious is what all the gods love...'. Scholarly analyses of Socrates' refutation of this definition have focused on its validity or even its 'truth'. By contrast, this paper restricts itself to the refutation's logical structure, particularly the way Socrates juxtaposes the agreed-upon premises to derive a double or 'chiastic' contradiction. In this article, I lay out the details of Socrates' ingenious logical construction, without regard to its validity or fallaciousness, and (...) argue that the chiastic contradiction alone makes possible Socrates' refutation of Euthyphro's claim to expertise in the realm of to hosion.

Plato's Euthyphro is a dialogue about the virtue of piety. It is also one of the aporetic dialogues, ending in apparent failure to discover what piety is. It is common to understand the dialogue as teaching lessons about other things, about definition, for instance, or about the logic of refutation. About piety, however, it is thought to teach us only negatively, showing a few of the many things which piety is not.My thesis, on the contrary, is that there is a (...) positive account of the nature of piety in the dialogue; it is, moreover, an account which cannot be separated from the other lessons which the dialogue teaches. I shall find it necessary to expose the structure of the logical lessons in order to develop my account of the holy. (shrink)
