‘When a lively-minded ingenuous youth hears all this, what will be his
conclusion? “Will he,” in the language of Pindar, “make justice his
high tower, or fortify himself with crooked deceit?” Justice, he
reflects, without the appearance of justice, is misery and ruin;
injustice has the promise of a glorious life. Appearance is master of
truth and lord of happiness. To appearance then I will turn,—I will put
on the show of virtue and trail behind me the fox of Archilochus. I
hear some one saying that “wickedness is not easily concealed,” to
which I reply that “nothing great is easy.” Union and force and
rhetoric will do much; and if men say that they cannot prevail over the
gods, still how do we know that there are gods? Only from the poets,
who acknowledge that they may be appeased by sacrifices. Then why not
sin and pay for indulgences out of your sin? For if the righteous are
only unpunished, still they have no further reward, while the wicked
may be unpunished and have the pleasure of sinning too. But what of the
world below? Nay, says the argument, there are atoning powers who will
set that matter right, as the poets, who are the sons of the gods, tell
us; and this is confirmed by the authority of the State.
‘How can we resist such arguments in favour of injustice? Add good
manners, and, as the wise tell us, we shall make the best of both
worlds. Who that is not a miserable caitiff will refrain from smiling
at the praises of justice? Even if a man knows the better part he will
not be angry with others; for he knows also that more than human virtue
is needed to save a man, and that he only praises justice who is
incapable of injustice.
‘The origin of the evil is that all men from the beginning, heroes,
poets, instructors of youth, have always asserted “the temporal
dispensation,” the honours and profits of justice. Had we been taught
in early youth the power of justice and injustice inherent in the soul,
and unseen by any human or divine eye, we should not have needed others
to be our guardians, but every one would have been the guardian of
himself. This is what I want you to show, Socrates;—other men use
arguments which rather tend to strengthen the position of Thrasymachus
that “might is right;” but from you I expect better things. And please,
as Glaucon said, to exclude reputation; let the just be thought unjust
and the unjust just, and do you still prove to us the superiority of
justice’...
The thesis, which for the sake of argument has been maintained by
Glaucon, is the converse of that of Thrasymachus—not right is the
interest of the stronger, but right is the necessity of the weaker.
Starting from the same premises he carries the analysis of society a
step further back;—might is still right, but the might is the weakness
of the many combined against the strength of the few.
