Question

Passage:

Historically, the transition from the qualitative pursuits of alchemy to the quantitative rigor of modern chemistry is often heralded as a paradigmatic shift catalyzed by Robert Boyle in the seventeenth century. Boyle's seminal work, *The Sceptical Chymist* (1661), is frequently cited as the death knell for the Aristotelian theory of four elements and the Paracelsian *tria prima* (salt, sulfur, and mercury). However, recent historiography suggests that this conventional narrative oversimplifies the intellectual milieu of early modern Europe. While Boyle undeniably championed the mechanical philosophy—positing that all macroscopic phenomena could be explained by the size, shape, and motion of indivisible corpuscles—he did not entirely abandon the fundamental tenets of his alchemical predecessors.

Indeed, Boyle remained deeply invested in chrysopoeia, the alchemical pursuit of transmuting base metals into gold, until his death. His advocacy for a corpuscular theory of matter was not an outright rejection of transmutation but rather a theoretical framework that made it logically permissible. If all matter was composed of the same universal catholic matter differentiated only by corpuscular arrangement, then rearranging those corpuscles to transform lead into gold was theoretically possible. Thus, Boyle's critique in *The Sceptical Chymist* was aimed primarily at the epistemological foundations of Paracelsian theory, not the possibility of transmutation itself. He argued that the Paracelsian elements were not fundamental building blocks of nature but rather temporary compounds formed during the application of fire, which was the primary analytical tool of the alchemists.

Furthermore, Boyle's empiricism was heavily indebted to the robust laboratory traditions established by earlier alchemists like Joan Baptista Van Helmont. It was Van Helmont who first systematically deployed the balance in chemical experiments and recognized the conservation of mass during chemical reactions, principles that Boyle later refined and popularized. While Boyle criticized the intentional obscurity and mystical allegories of traditional alchemical texts, demanding instead transparent and replicable experimental reports, his methodological innovations were evolutionary rather than revolutionary. He systematically adopted and expanded upon the quantitative techniques of his predecessors, stripped them of their astrological contexts, and presented them within the emerging framework of the mechanical philosophy.

Therefore, the portrayal of Boyle as the first modern chemist who unilaterally vanquished the pseudoscience of alchemy obscures the deep continuities between the two fields. It is more accurate to view his work as a crucial inflection point where the meticulous experimental practices of alchemy were married to the ontological assumptions of the new mechanical philosophy, setting the stage for the chemical revolution of the late eighteenth century.

According to the passage, Boyle characterized the Paracelsian elements as which of the following?
