6.1
I will try also to show how he encouraged his companions to become skilled in discussion. Socrates held that those who know what any given thing is can also expound it to others; on the other hand, those who do not know are misled themselves and mislead others. For this reason he never gave up considering with his companions what any given thing is.To go through all his definitions would be an arduous task. I will say only enough to indicate his method of analysis.
6.2
His analysis of Piety — to take that first — was more or less as follows:Tell me, Euthydemus, what sort of thing is Piety, in your opinion?A very excellent thing, to be sure, he replied.Can you say what sort of man is pious?He who worships the gods, I think.May a man worship the gods according to his own will and pleasure?No, there are laws to be observed in worshipping the gods!
6.3
Then will not he who knows these laws know how he must worship the gods?I think so.Then does he who knows how he must worship the gods think that he must do so according to his knowledge, and not otherwise?He does indeed.And does everyone worship the gods as he thinks he ought, and not otherwise?I think so.
6.4
Then will he who knows what is lawful about the gods worship the gods lawfully?Certainly.Then does not he who worships lawfully worship as he ought?Of course.Yes, but he who worships as he ought is pious?Certainly.Shall we therefore rightly define the pious man as one who knows what is lawful concerning the gods?I at any rate think so.
