Aristotelianism, alchemy and corpuscularianism in the thirteenth century: the problem of substantial form and its corpuscular solution

The Avicennan text <i>De congelatione et conglutinatione lapidum</i> had a great influence on the alchemical thought of the thirteenth century. This Latin text disputed both the veracity of alchemy and the possibility of alchemical transmutation by arguing that art is inferior to nature and that the alchemists cannot manipulate a metal because its true characteristics are hidden from our senses; thus an alchemist cannot change something which is unknown to him. Newman's pioneer studies examined the diffusion and impact of the first Avicennan argument on medieval alchemy and he shed light on the art-versus-nature debate. This paper has a twofold aim: on the one hand it aims to further Newman's study by focusing on the second Avicennan argument, which is closely related to the problem of substantial form, and on the other hand it aims to show how the aforesaid problem paved the way for the emergence of corpuscularianism, which flourished during the early modern period. In this regard, it will become clear that the historiographical case of alchemy and its problem of substantial form can serve as an exegetical tool for 'bridging' the Middle Ages and the early modern period with respect to the relation between Aristotelianism and corpuscularianism.
