aristocracy. The Rise of the Third Estate was influential in the overthrow of the monarchy in the French Revolution in 1789. French thinking also evolved greatly, thanks to major discoveries in science by Newton, Watt, Volta, Leibniz, Buffon, Lavoisier, and Monge, among others, and their rapid diffusion throughout Europe through newspapers, journals, scientific societies, and theaters. Faith in science and progress was the driving force behind the first French Encyclopedia of Denis Diderot and Jean le Rond d'Alembert. The authority of the Catholic Church was weakened, partly by the conflicts between high and low clergy, partly by the conflict between the State and Jesuits, who were finally expelled from the Kingdom in 1764. The Protestants achieved legal status in France in 1787. The church hierarchy was in continual battle with the Lumieres, having many of their works banned, and causing French courts to sentence a Protestant, Jean Calas, to death in 1762 for blasphemy, an act which was strongly condemned by Voltaire. The explorations of the New World and the first encounters with American Indians also brought a new theme into French and European Literature; exoticism, and the idea of the Noble Savage, which inspired such works as Paul et Virginie by Jacques-Henri Bernardin de Saint-Pierre. The exchange of ideas with other countries also increased. British ideas were particularly important, particularly such ideas as constitutional monarchy and romanticism, which greatly influenced French writers, particularly in the following century. The visual arts of the 18th century were highly decorative and oriented toward giving pleasure, as exemplified by the Regency style and Louis XV style, and the paintings of François Boucher, Jean-Honoré Fragonard, Watteau and Chardin, and portrait painters Quentin de La Tour, Nattier and Van Loo. Toward the end of the century, a more sober style appeared, aimed at illustrating scenery, work, and moral values exemplified by Greuze, Hubert Robert and Claude Joseph Vernet. The leading figures in French music were François Couperin and Jean-Philippe Rameau, but they were overshadowed by other European composers of the century, notably Vivaldi, Mozart Haendel, Bach, and Haydn.
