This chapter engages in a critical encounter with the work of Stanley Cavell on cinema, focusing skeptical attention on the claims made for the contribution of cinema to the ethical character of democratic life. In 1757, Jean d'Alembert wrote an entry on "Genève" in the seventh volume of the Encyclopédie, the great encapsulation of the Enlightenment, of which he was also one of the general editors. Jean-Jacques Rousseau, born in Geneva, had contributed many entries to the Encyclopédie on music and political economy and was well known as a composer and patron of the theater. Determined to oppose Voltaire's suggestion that theater represented cultural and political progress, he wrote a public letter to his editor and friend. It was published in 1758 as Letter to M. d'Alembert on the Theatre. It provoked an extended public exchange and represented Rousseau's permanent break from d'Alembert, Diderot and all his former Enlightenment allies.
