Topic > Plato and Thrasymachus: Different Philosophies on Morality

Thrasymachus was a rhetorician whose oratory skills were praised by Dionysus of Halicarnassus as "pure, subtle, and capable of speaking concisely or with abundance of words" (Guthrie, 1969, p. .167). Thrasymachus believed, like most sophists, that justice was an obstacle to an individual's genuine interests: wealth, power, and pleasure. Thrasymachus conveys that justice is the interest and advantage of the strongest or “might makes right” (Plato, The Republic, 380 BC, pp. 338d-339a). Thrasymachus felt that conventional morality should be worn like a garment to hide underlying selfish and self-centered motivations. Justice is nothing more than a convention that serves the interests of legislators and if justice is wanted, the way forward is to acquire power instead of appealing to an absolute standard of morality. This is where Plato's theory and Thrasymachus' objections seem to reach their climax
