Seeing that they were always moving and running, from their running
nature they were called Gods or runners (Theous, Theontas); and when
men became acquainted with the other Gods, they proceeded to apply the
same name to them all. Do you think that likely?
Her. I think it very likely indeed.
Soc. What shall follow the Gods?
Her. Must not demons and heroes and men come next?
Soc. Demons! And what do you consider to be the meaning of this word?
Tell me if my view is right.
Her. Let me hear.
Soc. You know how Hesiod uses the word?
Her. I do not.
Soc. Do you not remember that he speaks of a golden race of men who
came first?
Her. Yes, I do.
Soc. He says of them-
But now that fate has closed over this race
They are holy demons upon the earth,
Beneficent, averters of ills, guardians of mortal men.
Her. What is the inference?
Soc. What is the inference! Why, I suppose that he means by the golden
men, not men literally made of gold, but good and noble; and I am
convinced of this, because he further says that we are the iron race.
Her. That is true.
Soc. And do you not suppose that good men of our own day would by him
be said to be of golden race?
Her. Very likely.
Soc. And are not the good wise?
Her. Yes, they are wise.
Soc. And therefore I have the most entire conviction that he called
them demons, because they were daemones (knowing or wise), and in our
older Attic dialect the word itself occurs. Now he and other poets say
truly, that when a good man dies he has honour and a mighty portion
among the dead, and becomes a demon; which is a name given to him
signifying wisdom. And I say too, that every wise man who happens to
be a good man is more than human (daimonion) both in life and death,
and is rightly called a demon.
Her. Then I rather think that I am of one mind with you; but what is
the meaning of the word "hero"? (eros)
Soc. I think that there is no difficulty in explaining, for the name
is not much altered, and signifies that they were born of love.
Her. What do you mean?
Soc. Do you not know that the heroes are demigods?
Her. What then?
Soc. All of them sprang either from the love of a God for a mortal
woman, or of a mortal man for a Goddess; think of the word in the old
Attic, and you will see better that the name heros is only a slight
alteration of Eros, from whom the heroes sprang: either this is the
meaning, or, if not this, then they must have been skilful as
rhetoricians and dialecticians, and able to put the question (erotan),
for eirein is equivalent to legein. And therefore, as I was saying, in
the Attic dialect the heroes turn out to be rhetoricians and
questioners. All this is easy enough; the noble breed of heroes are a
tribe of sophists and rhetors. But can you tell me why men are called
anthropoi?- that is more difficult.
Her. No, I cannot; and I would not try even if I could, because I
think that you are the more likely to succeed.
Soc. That is to say, you trust to the inspiration of Euthyphro.
Her. Of course.
Soc. Your faith is not vain; for at this very moment a new and
ingenious thought strikes me, and, if I am not careful, before
tomorrow's dawn I shall be wiser than I ought to be. Now, attend to
me; and first, remember that we of put in and pull out letters in
words, and give names as we please and change the accents. Take, for
