ArgumentThis article argues that during the seventeenth century chemistry achieved intellectual and institutional recognition, starting its transition from a practical art – subordinated to medicine – into an independent discipline. This process was by no means a smooth one, as it took place amidst polemics and conflicts lasting more than a century. It began when Andreas Libavius endeavored to turn chemistry into a teaching discipline, imposing method and order. Chemistry underwent harsh criticism from Descartes and the Cartesians, who reduced natural (...) phenomena to the mechanical affections of matter, leaving little room for chemistry as an independent discipline. Boyle rejected the chemical principles and promoted the fusion of chemistry with corpuscularianism. He did not reduce chemical phenomena to the mechanical affections of matter, but strived to promote chemistry as part of natural philosophy. Lemery gave strong impulse to the recognition of chemistry as a discipline in its own right by fostering a compromise of chemistry and mechanism. Lemery adopted the chemical principles, but did not see them as the ultimate ingredients of bodies. In order to promote chemistry, he distanced it from alchemy and pursued the reform of chemical terminology. (shrink)
