The Republic - pg. 76

"Now, as it seems, if a man who is able by wisdom to
become every sort of thing and to imitate all things
should come to our city, wishing to make a display
of himself and his poems, we would fall on our knees
before him as a man sacred, wonderful, and pleasing;
but we would say that there is no such man sacred,
wonderful, and pleasing; but we would say that there
is no such man among us in the city, not is it lawful
for such a man to be born there. We would send him
to another city, with myrrh poured over his head
and crowned with wool, while we ourselves would
use a more austere and less pleasing poet and teller of
tales for the sake of our benefit, one who would imitate
the style of the decent man and would say what he says
in those models that we set down as laws at the beginning,
when we undertook to educate the soldiers."
