In book I of Plato’s Republic, Socrates and Thrasymachus discuss the nature of justice. After Socrates deconstructs Polemarchus’s notion of justice, Thrasymachus eagerly interjects, posing a startling claim that initially perplexed me. Nonetheless, through class discussion and my own analysis, I ultimately gained a deeper understanding of Thrasymachus’s insights.
Once Socrates and Polemarchus abandon Polemarchus’s definition of justice, Thrasymachus inserts himself into their conversation.

According to our class discussion, Thrasymachus’s ideas are grounded in the assumption that a true ruler possesses relevant expertise. While a ruler in title only is prone to mistakes, a ruler with the appropriate expertise can perfectly serve his own advantage. Through this lens, all laws implemented by a true ruler are purposeful and beneficial to the ruler. The notion that laws must be rooted in reason and purpose made Thrasymachus’s argument more appealing to
