The so-called ‘redintegration experiment’ is traditionally at the center of the comments on the supposed Boyle/Spinoza controversy. A. Clericuzio influentially argued in his publications that, in De nitro, Boyle accounted for the ‘redintegration’ of saltpeter on the grounds of the chemical properties of corpuscles and “did not make any attempt to deduce them from mechanical principles”. By way of contrast, this paper argues that with his De nitro Boyle wanted to illustrate and promote his new corpuscular or mechanical philosophy, and (...) that he made significant attempts to explain the phenomena in terms of mechanical qualities. Boyle had borrowed the ‘redintegration experiment’ from R. Glauber and used it in an attempt to demonstrate that his philosophy was superior to the Peripatetic and Paracelsian theory. Consequently, Clericuzio’s characterization of the Boyle/Spinoza controversy as a discussion between a strict mechanical philosopher and a chemist is problematic and a wider view of Spinoza’s interpretation and its context gives a fairer picture.

Summary Robert Boyle did not subordinate chemistry to mechanical philosophy. He was in fact reluctant to explain chemical phenomena by having recourse to the mechanical properties of particles. For him chemistry provided a primary way of penetrating into nature. In his chemical works he employed corpuscles endowed with chemical properties as his explanans. Boyle's chemistry was corpuscular, rather than mechanical. As Boyle's views of seminal principles show, his corpuscular philosophy cannot be described as a purely mechanical theory of matter. Boyle's (...) classification of corpuscles allowed him to connect his corpuscular views of matter with chemistry. Boyle did not rule out the possibility of a classification of chemical substances based on their properties: his aim was to reform the received classification. (shrink)
