was bound and thrown into a ditch by the command of Euthyphro's father, who
sent to the interpreters of religion at Athens to ask what should be done
with him. Before the messenger came back the criminal had died from hunger
and exposure.

This is the origin of the charge of murder which Euthyphro brings against
his father. Socrates is confident that before he could have undertaken the
responsibility of such a prosecution, he must have been perfectly informed
of the nature of piety and impiety; and as he is going to be tried for
impiety himself, he thinks that he cannot do better than learn of Euthyphro
(who will be admitted by everybody, including the judges, to be an
unimpeachable authority) what piety is, and what is impiety. What then is
piety?

Euthyphro, who, in the abundance of his knowledge, is very willing to
undertake all the responsibility, replies: That piety is doing as I do,
prosecuting your father (if he is guilty) on a charge of murder; doing as
the gods do--as Zeus did to Cronos, and Cronos to Uranus.

Socrates has a dislike to these tales of mythology, and he fancies that
this dislike of his may be the reason why he is charged with impiety. 'Are
they really true?' 'Yes, they are;' and Euthyphro will gladly tell
Socrates some more of them. But Socrates would like first of all to have a
more satisfactory answer to the question, 'What is piety?' 'Doing as I do,
charging a father with murder,' may be a single instance of piety, but can
hardly be regarded as a general definition.

Euthyphro replies, that 'Piety is what is dear to the gods, and impiety is
what is not dear to them.' But may there not be differences of opinion, as
among men, so also among the gods? Especially, about good and evil, which
