"Cicero never hid the fact that he wrote his own On the Republic in imitation of, and as a corrective of, Plato’s more famous Republic. Indeed, Cicero reveled in the idea. Yet, his own work is never slavish. In book four of Cicero’s version—of which, sadly, very little survives and much of it only in fragments quoted in other works—Cicero openly criticizes Plato for several things. Even in his criticisms, though, Cicero is playful, with the participants of the dialogue noting that Plato seems to be exempt from all wrong doing."
