The Greco-Persian Wars appear in Jean-Jacques Rousseau’s account as a defining contrast between Greece’s earlier courage and its later subjection: the Greeks twice vanquished Asia before the arts and sciences, in his argument, had corrupted their manners. The victories establish the force of an uncorrupted civic character, while the history that follows turns their achievement into a warning about cultural decline.

Background and Stakes

Rousseau presents Greece as once peopled by heroes and emphasizes that its letters were still in their infancy when the Greeks twice defeated Asia. In this account, their victories belong to a period before the progress of the sciences had altered the disposition of the inhabitants. The contrast makes the wars more than a record of military success: they mark the strength Greece possessed before the moral change Rousseau associates with learning and refinement.

Cultural Decline and Conquest

Rousseau links the subsequent progress of the sciences to a dissoluteness of manners and the imposition of the Macedonian yoke. From then on, he says, Greece remained learned and voluptuous but also enslaved, experiencing through its revolutions no more than a change of masters. The passage thus sets the earlier victories against a later political condition in which intellectual distinction does not restore independence.

Rhetorical Significance

The wars serve as the passage’s initial measure of Greek strength, sharpening its argument that later cultural accomplishment did not preserve freedom. Rousseau completes the contrast by invoking Demosthenes: not even his eloquence could breathe life into a body enervated by luxury and the arts. The image makes the reversal stark: Greece had once defeated Asia, but eloquence could not revive it after the decline Rousseau describes.
