Thrasymachus Character Analysis in The Republic

A Sophist, or professional tutor and philosopher. Thrasymachus is the only real opposition to Socrates. Thrasymachus believes firmly that "justice is to the advantage of the stronger." Sophists as a group tended to emphasize personal benefit as more important than moral issues of right and wrong, and Thrasymachus does as well. Thrasymachus' depiction in Republic is unfavorable in the extreme. He appears conceited, given to boasts and bluster, and his frustration with Socrates and Socrates' method of approaching knowledge through questioning is evident. He leaves at the end of Book I, but his exit suggests he is frustrated and is aware that he has not successfully debated Socrates. Although the choice of name may be inspired by the historical Sophist Thrasymachus, the name literally means "schemer."
