The imperial examination system was known to Europeans as early as 1570. It received great attention from the Jesuit Matteo Ricci (1552–1610), who viewed it and its Confucian appeal to rationalism favorably in comparison to religious reliance on "apocalypse." Knowledge of Confucianism and the examination system was disseminated broadly in Europe following the Latin translation of Ricci's journal in 1614. During the 18th century, the imperial examinations were often discussed in conjunction with Confucianism, which attracted great attention from contemporary European thinkers such as Gottfried Wilhelm Leibniz, Voltaire, Montesquieu, Baron d'Holbach, Johann Wolfgang von Goethe, and Friedrich Schiller. In France and Britain, Confucian ideology was used in attacking the privilege of the elite. Figures such as Voltaire claimed that the Chinese had "perfected moral science" and François Quesnay advocated an economic and political system modeled after that of the Chinese. According to Ferdinand Brunetière (1849-1906), followers of Physiocracy such as François Quesnay, whose theory of free trade was based on Chinese classical theory, were sinophiles bent on introducing "l'esprit chinois" to France. He also admits that French education was really based on Chinese literary examinations which were popularized in France by philosophers, especially Voltaire. Western perception of China in the 18th century admired the Chinese bureaucratic system as favourable over European governments for its seeming meritocracy. However those who admired China such as Christian Wolff were sometimes persecuted. In 1721 he gave a lecture at the University of Halle praising Confucianism, for which he was accused of atheism and forced to give up his position at the university.
