VIII.4 A particular cause of corruption of the people

Great achie­ve­ments, espe­cially ones to which the peo­ple contri­bute greatly, make them so proud that it is no lon­ger pos­si­ble to lead them. Jealous of the magis­tra­tes, they become jea­lous of the magis­tracy ; enemy of those who govern, they are soon the enemy of the cons­ti­tu­tion. That is how the vic­tory of Salamis over the Persians cor­rup­ted the repu­blic of Athens1 ; that is how the defeat of the Athenians doo­med the repu­blic of Syracuse.2

The repu­blic of Marseille never expe­rien­ced these great swings from humi­lia­tion to great­ness ; it it also true that it always gover­ned itself wisely, and always pre­ser­ved its prin­ci­ples.
