In arguing against the likelihood of consciousness in non-human animals, Descartes advances a slippery slope argument that if thought were attributed to any one animal, it would have to be attributed to all, which is absurd. This paper examines the foundations of Thomas Willis’ comparative neuroanatomy against the background of Descartes’ slippery slope argument against animal consciousness. Inspired by Gassendi’s ideas about the corporeal soul, Thomas Willis distinguished between neural circuitry responsible for reflex behaviour and that responsible for cognitively or (...) consciously mediated behaviour. This afforded Willis a non-arbitrary basis for distinguishing between animals with thought and consciousness and those without, a methodology which retains currency for neuroscience today. (shrink)

This volume takes cue from the idea that the thought of no philosopher can be understood without considering it as the result of a constant, lively dialogue with other thinkers, both in its internal evolution as well as in its reception, re-use, and assumption as a starting point in addressing past and present philosophical problems. In doing so, it focuses on a feature that is crucially emerging in the historiography of early modern philosophy and science, namely the complexity in the (...) production of knowledge. The book explores the applicability of this approach to a long-considered armchair philosopher, namely René Descartes, who is now more and more understood as a full-blown scientist, networker, and intellectual éminence grise rather than as the mere philosopher of the cogito, as well as the originator of different ‘Cartesianisms’ which encompassed many ideas and approaches for long captured by dichotomic historiographical categories as rationalism and empiricism, or speculative and experimental philosophy. The essays gathered in the volume aim to address the ways in which Descartes’s philosophy evolved and was progressively understood by scientists, philosophers, and intellectuals from different contexts and eras, either by considering direct interlocutors of Descartes such as Isaac Beeckman and Elisabeth of Bohemia, early modern thinkers who developed upon his ideas and on particular topics as Nicolas Malebranche or Thomas Willis, those who adapted his overall methodology in developing new systems of knowledge as Johannes Clauberg and Pierre-Sylvain Régis, and contemporary thinkers from continental and analytic traditions like Emanuele Severino and Peter Strawson.

It is often assumed that in the collapse of the Aristotelian distinction between art and nature that results from the rise of mechanical philosophies in the early modern period, the collapse falls on the side of art. That is, all of the diversity among natures that was explained previously as differences among substantial forms came to be seen simply as differences in arrangements of matter according to laws instituted by the “divine artificer”, God. This paper argues that, for René Descartes, (...) the collapse occurs on both sides. Natures are artefacts of God, and human artefacts, under some conditions, can be classified as natures or, at least, continuous within nature. Drawing on developments across both horticulture and engineering in the 16th and 17th centuries, as well as Descartes’ mechanical philosophy, this paper explores challenges to the Aristotelian nature/art distinction. The question then is what, in the advent of this collapse, are human artificers doing when they construct artefacts? Are they replicating God’s powers by creating new natures, or are they doing something else, and if so, what might that be? It is argued that we should view human invention for Descartes not as creating new natures so much as discovering them. These findings have consequences for how we interpret Descartes’ use of the term “nature” in relation to automata and other artefacts produced by human hands. (shrink)
