Bernard Le Bovier de Fontenelle

Fontenelle was a popular figure in the educated French society of his period, by holding a position of esteem comparable only to that of Voltaire. Unlike Voltaire, however, Fontenelle avoided making important enemies. He balanced his penchant for universal critical thought with liberal doses of flattery and praise to the appropriate individuals in aristocratic society. Fontenelle forms a link between two periods of French literature: the 17th century beaux esprits of Corneille, Racine and Boileau, and the 18th century philosophes of Voltaire, D'Alembert and Diderot. According to Charles Augustin Sainte-Beuve, he deserves a place dans la classe des esprits infiniment distingués but is distinguished by being ought to be added by intelligence rather than by intellect and less by the power of saying much than by the power of saying a little well. There have been several collected editions of Fontenelle's works, the first being printed in 3 vols. at the Hague in 1728–1729. The best is that of Paris, in 8 vols., 1790. Some of his separate works have been frequently reprinted and also translated. The Pluralité des mondes was translated into modern Greek in 1794. Sainte-Beuve has an interesting essay on Fontenelle, with several useful references, in the Causeries du lundi, vol. iii. See also Villemain, Tableau de la littérature française au XVIIIe siècle; the abbé Trublet, Mémoires pour servir à l'histoire de la vie et des ouvrages de M. de Fontenelle (1759); A Laborde-Milaà, Fontenelle (1905), in the "Grands écrivains français" series; and L. Maigron, Fontenelle, l'homme, l'œuvre, l'influence (Paris, 1906). His Dialogues of the dead show both his erudition and wit by presenting invented but plausible dialogues between dead ancients, dead moderns and a whole book devoted to dialogues between an ancient and a modern. To Montaigne asking him if some centuries had more wise men than other, Socrates answers sadly, "The general order of natures seems very constant". In one of the books Roxelane and Anne Boleyn discuss about politics and the way for a woman to decide a man to marry her. The dialogue between Montezuma and Cortez allows the former to dismiss some myths about the wisdom in ancient Greece by quoting some counter-examples. In 1935, the lunar crater Fontenelle was named after him, and so was the asteroid 10069 Fontenelle, which was discovered in 1989.

In 1691 he was received into the French Academy in spite of the determined efforts of the partisans of the "ancients", especially Racine and Boileau, who on four previous occasions had ensured his rejection. He was thus a member both of the Academy of Inscriptions and of the Academy of Sciences. In 1697 he became perpetual secretary to the Academy of Sciences, an office he held for forty-two years. It was in this official capacity that he wrote the Histoire du renouvellement de l'Académie des Sciences (Paris, 3 vols., 1708, 1717, 1722) containing extracts and analyses of the proceedings, and also the éloges of the members, written with great simplicity and delicacy. Perhaps the best known of his éloges, of which there are sixty-nine in all, is that of his uncle Pierre Corneille. This was first printed in the Nouvelles de la republique des lettres (January 1685) and, as Vie de Corneille, was included in all the editions of Fontenelle's Œuvres. The other important works of Fontenelle are his Éléments de la géometrie de l'infini (1727) and his Théorie des tourbillons (1752). In the latter he supported the views of René Descartes concerning gravitation, material that by that time had effectively been superseded by the work of Isaac Newton. He is noted for the accessibility of his work – particularly its novelistic style. This allowed non-scientists to appreciate scientific development in a time where this was unusual, and scientists to benefit from the thoughts of the greater society. If his writing is often seen as trying to popularize the astronomical theories of Descartes, whose greatest exponent he is sometimes considered, it also appealed to the literate society of the day to become more involved in "natural philosophy," thus enriching the work of early-Enlightenment scientists. In spite of the inarguable value and quality of his writings, he had no serious pretensions to original scientific or mathematical work, but did not let that stop him from outspoken support for Descartes' proposed conceptions of the roles of vortices in physics.
