Philosophical and Scientific Empiricism and Rationalism in the Seventeenth and Eighteenth Centuries

Abstract

The paper critically evaluates two commonplaces of historiography. One is that Empiricism as a philosophical movement of the seventeenth and early eighteenth centuries was opposed to Rationalism corresponding to an English-Continental division of personnel. The other commonplace is the view that the main accomplishments of eighteenth century science were mainly taxonomic in contrast to the remarkable conceptual innovations of Galileo, Descartes and Newton. I point instead, as characteristic of eighteenth century science, to an energetic blend of hands-on experimentalism, methodological caution about the employment of metaphysical concepts, and imaginative speculation where the powers of ‘matter’ unassisted by God were concerned, with Buffon playing a leading role. Kant’s attempt to confine empirical reasoning and the Newtonian system to the (mere) appearances reflects widely held views about the ‘veiling’ of nature behind our ideas in eighteenth century methodological reflection but serves mainly to ground his appeals to the supersensible element in human agency.
