“ Years advance, and the sun of philosophy, unlike that of Heracleitus, sets never to rise again. This order of education should be reversed; it should begin with gymnastics in youth, and as the man strengthens, he should increase the gymnastics of his soul. Then, when active life is over, let him finally return to philosophy. ‘You are in earnest, Socrates, but the world will be equally earnest in withstanding you—no more than Thrasymachus.’ Do not make a quarrel between Thrasymachus and me, who were never enemies and are now good friends enough. ”
Thrasymachus
Definition and stakes
Thrasymachus, a figure from Plato’s Republic, embodies the challenge to Socratic ideals through his assertion that “justice is the interest of the stronger.” In Plato’s dialogues, he debates Socrates on whether injustice leads to greater personal advantage, portraying morality as a means of power. C. E. M.
Joad later reinterprets Thrasymachus’ claim, emphasizing its dual implications for both worldly and divine interests. While other authors, such as Hudson and Arrigoni, briefly mention “thrush” in naturalist contexts, the central exploration of Thrasymachus remains grounded in philosophical discussion, revealing lasting tensions between justice, authority, and ethical relativism.
Quotes about “Thrasymachus”
Plato,
The Republic of Plato
(1901)
“ You appear rather, I replied, to have no care or thought about us, Thrasymachus—whether we live better or worse from not knowing what you say you know, is to you a matter of indifference. Prithee, friend, do not keep your knowledge to yourself; we are a large party; and any benefit which you confer upon us will be amply rewarded. For my own part I openly declare that I am not convinced, and that I do not believe injustice to be more gainful than justice, even if uncontrolled and allowed to have free play. ”
Plato,
The Republic of Plato
(1901)
“ For mankind censure injustice, fearing that they may be the victims of it and not because they shrink from committing it. And thus, as I have shown, Socrates, injustice, when on a sufficient scale, has more strength and freedom and mastery than justice; and, as I said at first, justice is the interest of the stronger, whereas injustice is a man’s own profit and interest. Thrasymachus, when he had thus spoken, having, like a bath-man, deluged our ears with his words, had a mind to go away. ”
