Three opinions about Justice in Bk 1 are expressed;
1. Cephalus (the head, the chief) = telling the truth and giving back what is owed
2. Polemarchus (one who begins, or leads a war) = do good to friends and harm to enemies
3. Thrasymachus (bold fighter) = advantage of the strong
Justice, ton dikaion, righteousness or goodness is all these things. The righteous man does tell the truth and gives back what is owed; he does good to his friends and harm to his enemies; he has the advantage over other b/c he possesses the strength of being beyond the law and obedient to the law.
This set of three is repeated in the three types of good presented by Glaucon (the Eurydice figure)
1. good enjoyed for its own sake
2. good enjoyed for its sake and what it produces
3. good produced from something that is hateful (which is where Glaucon says most people equate Justice)
And this set of three is reiterated in the idea of justice as a mean between two extremes
1. best = doing injustice w/o penalty
2. justice = not v. great, but not too painful; doing some smaller injustices w/o penalty of severe punishment
3. worst = suffering injustice w/o revenge
This set of three is like unto the setting of the dialogue, namely
1. Acropolis (Olympus; realm of the gods, or the land of light & life)
2. the main or middle city
3. Peiraeus (Hades; realm of the dead, darkness & chaos)
This is parallel to the metaphysical states of
But Glaucon/Eurydice, who has accosted Socrates/Orpheus in his return to the light, suggests that most people live in that limbo realm of the long grey day - justice is a compromise, and the best that we can hope for, in this life and the next, although not too thrilling or inspiring is at least not too painful.
The Acropolis/Olympus of doing injustice w/o penalty, is like the Playboy mansion, the bling of the gangsta, the pimp with the money and the babes and the convertible. Most of us will not achieve that, but if we were able to with impunity we would jump at that chance. Who, after all, wants to be a millionaire?
The Peiraeus/Hades of suffering injustice is a horrible prospect; malaka; utter degradation and despair coupled with eternal pain. No one wants that and the fear of its prospect keeps most people, as Nietzsche pointed out, from "aspiring to greatness". We are like Macbeth,
To be the same in thine own act and valour
As thou art in desire? Wouldst thou have that
Which thou esteem'st the ornament of life,
And live a coward in thine own esteem,
Letting 'I dare not' wait upon 'I would,'
Like the poor cat i' the adage?
