Chemical Philosophy in the 16th and 17th Centuries
This chapter provides the philosophical background for the discussion of Robert Boyle’s chemical philosophy by highlighting the most relevant theories that either influenced Boyle or to which Boyle was responding. The chapter begins by addressing the vitalistic character of Renaissance alchemy. The chapter then discusses the Scholastic theory of substantial form, to which Boyle seeks to provide an alternative. After this, the chapter addresses the Paracelsian spagyria and theory of the tria prima, since these come under specific attack in Boyle’s writings. The doctrines of semina rerum and minima naturalia are then discussed as they relate to vitalistic corpuscularian theories of matter. Finally, the theories and work of early modern alchemists Daniel Sennert and Jan Baptista van Helmont are discussed in detail since the experiments of these alchemists had a significant impact on the Boyle’s experimental work.
