... Here Thrasymachus, who has made several attempts to interrupt, but has
hitherto been kept in order by the company, takes advantage of a pause and
rushes into the arena, beginning, like a savage animal, with a roar.
'Socrates,' he says, 'what folly is this?--Why do you agree to be
vanquished by one another in a pretended argument?' He then prohibits all
the ordinary definitions of justice; *337* to which Socrates replies that
he cannot tell how many twelve is, if he is forbidden to say 2 x 6, or
3 x 4, or 6 x 2, or 4 x 3. At first Thrasymachus is reluctant to argue; but
at length, *338* with a promise of payment on the part of {xx} the company
and of praise from Socrates, he is induced to open the game. 'Listen,' he
says, 'my answer is that might is right, justice the interest of the
stronger: now praise me.' Let me understand you first. Do you mean that
because Polydamas the wrestler, who is stronger than we are, finds the
eating of beef for his interest, the eating of beef is also for our
interest, who are not so strong? Thrasymachus is indignant at the
illustration, and in pompous words, apparently intended to restore dignity
to the argument, he explains his meaning to be that the rulers make laws
for their own interests. *339* But suppose, says Socrates, that the ruler
or stronger makes a mistake--then the interest of the stronger is not his
interest. Thrasymachus is saved from this speedy downfall by his disciple
Cleitophon, who introduces the word 'thinks;' *340* --not the actual
interest of the ruler, but what he thinks or what seems to be his
interest, is justice. The contradiction is escaped by the unmeaning
evasion: for though his real and apparent interests may differ, what the
ruler thinks to be his interest will always remain what he thinks to be
his interest.
Of course this was not the original assertion, nor is the new
interpretation accepted by Thrasymachus himself. But Socrates is not
disposed to quarrel about words, if, as he significantly insinuates, his
adversary has changed his mind. In what follows Thrasymachus does in fact
withdraw his admission that the ruler may make a mistake, for he affirms
that the ruler as a ruler is infallible. *341* Socrates is quite ready to
accept the new position, which he equally turns against Thrasymachus by
the help of the analogy of the arts. *342* Every art or science has an
interest, but this interest is to be distinguished from the accidental
interest of the artist, and is only concerned with the good of the things
or persons which come under the art. And justice has an interest which is
the interest not of the ruler or judge, but of those who come under his
sway.
