The Pursuit of Justice in Plato's Republic

The pursuit of justice in the Republic commences when the elderly, wealthy Cephalus suggests that justice involves nothing more than telling the truth and repaying one's debts. But Socrates points out that by following these simple rules without exception could have dire consequences. In an effort to avoid such difficulties, Polemarchus offers a refinement of the definition by suggesting that justice means "giving to each what is owed". The new definition codifies formally our deeply-entrenched practice of seeking always to help our friends and harm our enemies. Thrasymachus recommends that justice should be seen as the advantage of the stronger because those in positions of power simply use their might to decree what shall be right. Glaucon and Adeimantus continue with the challenge concerning the meaning and the nature of justice. According to Glaucon the pursuit of justice disadvantages the just when they are deprived of the social rewards for their behaviour because justice is a social compromise. It is well known that people ignore the demands of justice when certain opportunities arise. Adeimantus places the emphasis on the condition of the individual soul, and of the individual himself, rather than the strength of justice over injustice. However not everyone will agree that justice should be defended as praiseworthy for its own sake, rather than for the extrinsic advantages that may result from its practice. Socrates expounds on the importance of justice in a simple though ambiguous sense, pointing to the fact that true justice must also contribute to the self-fulfilment of the just man. The just city serves the primary purpose of illuminating the just soul which is liberated from the subjection of injustice.
