Euthyphro Outline
Setting: King-Archon's Court
Characters: Socrates, Euthyphro
Definition 1: Piety is doing what I am doing now, 5d
Objection: does not have proper form.
Socrates seeks
(a) some one thing 6d
(b) a model 6e
Definition 2: Piety is what is dear to (loved by) the gods. 7a
Elenchus (Refutation): The same things are both god-loved and god-hated. 8a
Definition 3: Piety is what all the gods love. 9e
Elenchus:
(a) Is it loved because it is pious?
or
(b) Is it pious because it is loved? 10a
Socrates objects that Euthyphro's definition is of the form (b) not (a).
It describes an effect, or piety as having something happen accidentally to it.
Elenchus: How can we construe "care of" in this definition?
It is absurd to say that we are pious in order to benefit the gods.
Service enables the thing served to achieve a fine end; but this is absurd to say about our service to the gods.
This amounts to saying that if we are pious, we give the gods what pleases them. So we are back to Definition 2 or 3.
