Socrates and Thrasymachus fought three times. According to a query on China Education Online, Socrates and Thrasymachus had three rounds of dialogue. In the first round of rebuttal, Socrates very keenly grasped the weakness of the "stronger" in the argument "justice is the interest of the strong". Thrasymachus further argued that "the so-called truly strong people do not make mistakes" and they can always come up with ways to benefit themselves and realize their "intentional" interests. The two sides began the second round of argument. It is the so-called "dispute of skills". Socrates promoted people. Each skill serves its object, and the ruler also serves the people. Finally, the two started a third round of debate on Thrasymachus's proposition that "the unjust are more advantageous". This round of debate was Socrates' acceptance of Gelaocon's will, which convinced Gelaocon that "justice is beneficial" and made Thrasymachus admit his mistake. Socrates and Thrasymachus were both great philosophers with very high levels of thought and debating skills. This wonderful argument has passed the test of time and is still of research value today.
