Euthyphro:  Accusations - corruption of youth, atheism.  Euthyphro is accusing his father of the murder of a slave.
 -Gods.  Socrates is "a maker of gods, and . . . (he) creates new gods while not believing in the old gods." 
 Euthyphro claims that he is doing a pious act by prosecuting his father.  However, Socrates claims that this may be an impious thing.  (Euthyphro is supposed to be an expert in such matters.)

1.  What is piety, and what is impiety?  Reference to forms at 5d.  Prosecuting someone guilty of a crime is piety, and not doing so is impiety.  
 Socratic critique:  Euthyphro is not answering the question in a generic sense, he is simply stating one instance of piety and impiety; Socrates wants a better definition.   Euthyphro's definition does not give the "form" of piety, no essence.   Avoid the use of examples.

2.  Piety is that which is pleasing (dear to) the gods, and impiety is that which is not dear to them.  
 Socratic critique:  The gods are admitted to having differences among themselves, so what may be pleasing to some gods may be displeasing to others.  This would imply that one thing may be both pious and impious at the same time, a contradiction.  

3.  The pious is what all the gods love (9d) and what they all hate is impious.
 Socratic critique:  Are acts right because they are commanded, or are they commanded because they are right?  All that Euthyphro's definition does is to tell something about the acts - that the gods approve of them, not that they are pious or impious.  Add divine command theory.

4.  Knowledge of how to give to and beg from the gods.    Three tries here:  Care of the Gods. - No benefit to them.  2) Service to the gods; What service?   3) Pleasing to them, Give to, beg from.  4) no benefit.  15c=circular.
 Socratic Critique:  What does this have to do with the care of the gods?  If Euthyprho is right, piety would make the gods better. But Euthyprho agrees that this is wrong.  Euthyphro amends his statement and says that "care" is a service to the gods.  The Socratic analysis in this case is to ask what aim is achieved by serving the gods.  The answer Euthyphro gives is that piety is pleasing to the gods.  But this is the same as what is dear to them = circular.
