The Rationalist and Empirical Spirit

  • Chapter
The Supplément to the Encyclopédie

Abstract

Jacques Proust has suggested that such post-Encyclopédie ventures as the Supplément should be studied for further information about the literary life of the period.1 As demonstrated above, the history of the publication of the Supplément provides information of this sort in great detail. A study of the text of the work likewise furnishes insights into many intellectual tendencies of pre-Revolutionary France. These currents can be described in general as the rationalist and empirical, the non-mechanist and sentimental, and the reformist. Since they did not develop separately and simultaneously, but rather grew from each other, the Supplément of the mid-1770’s is a more complete source of evidence of these trends than the earlier Encyclopédie . The following chapters summarize, and illustrate with textual references, the expression of these different approaches in the Supplément.

Butts concludes that d’Alembert professed empiricism in order to fight metaphysics and because he agreed with other points connected with empiricism, such as religious scepticism. D’Alembert’s method, however, was Cartesian: he wanted to reduce knowledge to principles, and he assigned a high place to mathematics.

Abraham Wolf, A History of Science, Technology, and Philosophy in the Eighteenth Century (New York: The Macmillan Co., 1939), p. 501, observes that progress in agriculture in the eighteenth century was mainly of an empirical nature. It was not until the nineteenth century that scientists began to understand their information.
