Recap – Lessons 7-9

Socrates’ turn to ethical questions on how one should live a good life was characterized by (1) the subjects of his inquiry, for example, in The Republic, the question what is justice?; and (2) the technique he employed – dialectic – which provided an example of how one should authentically seek knowledge. Compared to the technique employed by the sophists, which was to “win” an argument without particular regard for the truth, dialectic was both more collaborative and more open-ended. It could also be more frustrating, as the discussions rendered by Plato didn’t always yield a definitive conclusion, and we’re often left to develop our own answers.

That was the case after our first reading from The Republic. Your answers to the question, what is justice?, clustered around the notions of it being external and based on punishment and reward. As we read, Socrates dealt with similar formulations from Cephalus, Polemarchus, Thrasymachus, and Glaucon. Each fell short of providing a satisfactory conception. Glaucon proposed perhaps the greatest challenge to any conception of justice by retelling the story of Gyges Ring: what would you do if you could get away with anything?

To answer, Socrates and his companions undertake an elaborate thought experiment where they build a city from scratch, the goal being to first identify where justice resides in the city, then to find analogues in the individual. Our second reading from The Republic described the virtues – wisdom, courage, and moderation – as they appear in both the city and the soul. Justice, it’s finally agreed, is harmony among these virtues, with each performing its function to sustain that balance.

Since justice is internal and not purely motivated by reward and punishment, Socrates and Plato have to take up the final task of answering why one should be just. By way of explaining, Socrates relates the allegory of the cave, which you skillfully rendered for your third assignment. As a metaphor for Plato’s theory of knowledge (the divided line), the story relays the struggle entailed for humans to break free from the comforts of illusion. There’s also a caution: sharing newly acquired wisdom may be hazardous to your health. The allegory also contains a mystery, which some of you identified: who freed the prisoner, and what was his/her status?
