What does Thrasymachus mean by "justice is really the good of another"

Question: What does Thrasymachus mean by "justice is really the good of another" (343c)!.!?

For his first position on justice he says "justice is nothing other than the advantage of the stronger” (338c)!. But I don't see what he means by his second position, “justice is really the good of another, the advantage of the stronger and the ruler, and harmful to the one who obeys and serves” (343c)!.

My teacher said it can be implied that he means justice is the disadvantage of the stronger!. How is that!?Www@QuestionHome@Com

It is the disadvantage for the stronger meaning the rulers because eventually the people will rebel!. The concept of Justice here is subjective and based on their era, but we can apply it to our era with the Bush Administration!. Bush has set unreasonable standards and has often invaded privacy in his quest to fight terror, what he deems as justice is based on convenience to what HE thinks will work best, what the RULER thinks will work best!. But does it truly benefit the people!? Justice is the standard set by society, typically the rulers, when they set these standards they set them according to what benefits them the most and what keeps the people in check (the rich get richer the poor get poorer)!. When the people act in a manner of injustice they are going against justice in the form of oppression and thus are more freer than if they were a slave to the rules because they act in their own best interest instead of the rulers best interest!. If that did not make sense drop me an email, I'll try to elaborate!.Www@QuestionHome@Com
