 In his original presentations, Buffon conceptualized these internal molds and specifying organic molecules to have originated from divine creation. As the Natural History progressed, however, Buffon increasingly viewed the organic molecules to be formed from an original undifferentiated “brute” matter, and the internal molds themselves were seen to arise spontaneously, obtaining their specificity of action purely from the differential forces of attraction between different shapes of organic particles (Buffon “De la Nature. Seconde vue”, 1765, [OP, 38–41]).
