Abstract

The article suggests that the position ascribed to thrasymachus in book i of plato's "republic" may be confused but need not be self-contradictory. A formal argument is constructed that derives his conclusion from premisses based on things he says, though not always in the language he uses. It is not suggested that plato ascribes this argument to thrasymachus, but only that it is consistent and intelligible in itself and compatible with what thrasymachus does say
