Oh Socrates...

Poor Euthyphro, Socretes just toys with him and then shows him that he can't figure out what he believes in.  I'm sure Euthyphro knows what he believes but Socretes, the ever-clever thinker, keeps leading his arguments around in circles so that Euthyphro never really gets a word in that is 'constructive' to his beliefs. 

This does on the other hand prove Socretes' skill at logic and argument.
