Plato ("Statesman" 262de) rejected the Greek–barbarian dichotomy as a logical absurdity on just such grounds: dividing the world into Greeks and non-Greeks told one nothing about the second group, yet Plato used the term barbarian frequently in his seventh letter. In Homer's works, the term appeared only once ("Iliad" 2.867), in the form () ("of incomprehensible speech"), used of the Carians fighting for Troy during the Trojan War. In general, the concept of "barbaros" did not figure largely in archaic literature before the 5th century BC. It has been suggested that the "barbarophonoi" in the "Iliad" signifies not those who spoke a non-Greek language but simply those who spoke Greek badly.
