I contributed an entry on Voltaire's philosophical novel Candide and an entry on 18th-century writer Antoine-François Prévost d'Exiles.
Excerpt from the entry on Candide:
The richness of Candide lies in the fact that the book reveals popular eighteenth-century philosophical theories, ones which are also linked to the Enlightenment. Another central theme in the story involves the triumph of action over scholarly discourse, the latter which ultimately proves to be inept. Several characters embody the type of false savant hated by Voltaire, especially Candide’s tutor, Pangloss whose mechanical repetitions of the phrase “Tout va bien…” is directly contradicted by the accumulation of misfortunes befalling the characters. Throughout Candide, the narrator mocks characters who think they possess knowledge even though they do not understand its meaning, merely repeating ready-made sentences summarizing philosophical theories and doctrines. Between Pangloss’s optimism and Martin’s pessimism, it is only after having traveled the world and lived through trying experiences that Candide creates his own way of understanding the world. His quest could thus be understood as a search for happiness. In fact, one of the main topics of discussion in salons of the mid-18th century was the possibility of earthly happiness for every man and no longer in a heavenly paradise for a selected few after death.
There are three places in the narrative where this happiness is possible: Westphalia, Eldorado, and at the end of the tale, in Candide’s garden. Each corresponds to an ideal: ignorance of the problems of the world in the gardens of the castle of Thunder-ten-tronckh; the utopia of the Enlightenment put into practice in Eldorado; finally, the culture of one’s own happiness in the face of the problems of society. In the end, Voltaire shows that real happiness can only be achieved by working on oneself, focusing on human problems rather than metaphysical ones, and acting concretely.
Excerpt from the entry on Antoine-François Prévost d'Exiles:
This superiority of the sensitive man, the honored hero of the eighteenth-century novel, implies a clear renunciation of the imperatives of seventeenth-century moralist philosophy, which postulated the possibility of controlling the passions by way of the conscience. The equanimity and repose, which characterized the French conception of the honnête homme, gave way to an entirely different virtue, one which could only be acquired by the hardship and trials of multiple excessive passions. It was no longer a matter of being oneself against everything, but of allowing oneself to be invaded and transformed by passion. The legitimacy that Prévost’s novel accords to irrational and paroxysmal behavior, to the spectacular manifestations of sentiment, was entirely new in 1731. In fact, it did not appear as a literary motif until later in the century, and is exemplified in Denis Diderot’s La Religieuse (1780)
