asked whether the just is always the pious, or the pious always the just;
and whether there may not be justice where there is not piety; for justice
is the more extended notion of which piety is only a part. Do you dissent?

EUTHYPHRO: No, I think that you are quite right.

SOCRATES: Then, if piety is a part of justice, I suppose that we should
enquire what part? If you had pursued the enquiry in the previous cases;
for instance, if you had asked me what is an even number, and what part of
number the even is, I should have had no difficulty in replying, a number
which represents a figure having two equal sides. Do you not agree?

EUTHYPHRO: Yes, I quite agree.

SOCRATES: In like manner, I want you to tell me what part of justice is
piety or holiness, that I may be able to tell Meletus not to do me
injustice, or indict me for impiety, as I am now adequately instructed by
you in the nature of piety or holiness, and their opposites.

EUTHYPHRO: Piety or holiness, Socrates, appears to me to be that part of
justice which attends to the gods, as there is the other part of justice
which attends to men.

SOCRATES: That is good, Euthyphro; yet still there is a little point about
which I should like to have further information, What is the meaning of
'attention'? For attention can hardly be used in the same sense when
applied to the gods as when applied to other things. For instance, horses
are said to require attention, and not every person is able to attend to
them, but only a person skilled in horsemanship. Is it not so?
