Abstract
The text shortly introduces Rousseau’s De l’imitation théatrale (1764). Rousseau’s writing is basically a translation of the first pages of Book X of Plato’s Republic. On the one hand, Rousseau shares with Plato the ethical rigor that, in view of a certain political project, leads to the moral condemnation of theatrical practices. On the other hand, the metaphysical assumptions on which Plato’s critique relies are much heavier than those of Rousseau, whose sensualistic nominalism is incompatible with the metaphysical realism about universals that underlies the arguments of Book X of the Republic. In this respect, it is surprising that Rousseau refers to Book X rather than Book III, in which the same critique of theatrical spectacles is developed from a psychological and moral point of view.
