This paper discusses the materialist views of Margaret Cavendish, focusing on the relationships between her views and those of two of her contemporaries, Thomas Hobbes and Henry More. It argues for two main claims. First, Cavendish's views sit, often rather neatly, between those of Hobbes and More. She agreed with Hobbes on some issues and More on others, while carving out a distinctive alternative view. Secondly, the exchange between Hobbes, More, and Cavendish illustrates a more general puzzle about just what (...) divided materialists from their opponents. Seemingly straightforward disagreements about whether incorporeal substances exist turn out to be more complex ones in which the nature of those things is disputed at the same time as their existence.

The generation of animals was a difficult phenomenon to explain in the seventeenth century, having long been a problem in natural philosophy, theology, and medicine. In this paper, I explore how generation, understood as epigenesis, was directly related to an idea of rational nature. I examine epigenesis—the idea that the embryo was constructed part-by-part, over time—in the work of two seemingly dissimilar English philosophers: William Harvey, an eclectic Aristotelian, and Margaret Cavendish, a radical materialist. I chart the ways that they (...) understood and explained epigenesis, given their differences in philosophy and ontology. I argue for the importance of ideas of harmony and order in structuring their accounts of generation as a rational process. I link their experiences during the English Civil war to how they see nature as a possible source for the rationality and concord sorely missing in human affairs. (shrink)

Animals – both tame and wild, as metaphors and as real presences – populate many of More’s works. In this essay, I show that, from the early Psychodia Platonica to the Divine Dialogues, animals are at the core of key metaphysical issues that reverberate on the levels of psychology and ethics. In particular I discuss three main aspects: the role of animals in More’s critique of atheism, both as safeguard for the body–soul interaction and as proofs of divine providence in (...) nature; the problem of evil in the universe, and how to justify the existence of ‘evil’ animals in particular; the differentiation between animals and humans, especially on the basis of their respective possibility of attaining happiness. In all three cases, I argue that More attempts to ‘tame’ the nature of animals, and yet that he is aware that ‘animality’ remains partly untamed. (shrink)

Henry More was an expounder of Cambridge Platonism, as he largely relied on a Platonicinspired standpoint in pursuing his aims: the demonstration of the immortality of soul, the critique of atheism and religious enthusiasm. He maintains that soul emanates from God (being therefore not created and pre-existing body) and argues for the existence of a spirit of nature as means to explain natural phenomena, which cannot be accounted for only in mechanical terms. Moreover, he argues for the extended nature of (...) God and spirits, as only in this way they can act on the world. Accordingly, More rejects Descartes’s theory of immaterial substance, but relies on his ontological argument provide a demonstration of the existence of God. His critique to enthusiasm (especially that one characterizing Neoplatonic mysticism) is medical, as he distinguishes between a rational, religious inspiration, and a melancholic one. (shrink)

Since the dawn of philosophy, the paradoxical interconnection between the continuous and the discrete plays a central rôle in attempts to understand the ontology of the world, while defying all attempts at consistent formulation. I investigate the relation between (classical) logic and concepts of “space” and “time” in physical and metaphysical theories, starting with the Greeks. An important part of my research consists in exploring the strong connections between paradoxes as they appear and are dealt with in ancient philosophy, and (...) their re-appearance in early modern natural philosophy, as well as in the foundations of contemporary science and mathematics. The way paradoxes are dealt with sheds light on a theory’s hidden metaphysical assumptions, especially with respect to matter, space, time and causation, it defines its ontological signature. This conclusion led me to the in-depth study of early modern natural philosophy, the origin of natural science, especially the influences ancient thinkers had on the new conceptions of space, time and causation developed by Newton, Huygens and Leibniz.

This paper examines connections between concepts of space and extension on the one hand and immaterial spirits on the other, specifically the immanentist concept of spirits as present in rerum natura. Those holding an immanentist concept, such as Thomas Aquinas, typically understood spirits non-dimensionally as present by essence and power; and that concept was historically linked to holenmerism, the doctrine that the spirit is whole in every part. Yet as Aristotelian ideas about extension were challenged and an actual, infinite, dimensional (...) space readmitted, a dimensionalist concept of spirit became possible—that asserted by the mature Henry More, as he repudiated holenmerism. Despite More’s intentions, his dimensionalist concept opens the door to materialism, for supposing that spirits have parts outside parts implies that those parts could in principle be mapped onto the parts of divisible bodies. The specter of materialism broadens our interest in More’s unconventional ideas, for the question of whether other early modern thinkers, including Isaac Newton, followed More becomes a question of whether they too unwittingly helped usher in materialism. This paper shows that More’s attack upon holenmerism fails. He illegitimately injects his dimensionalist concept of spirit into the doctrine, failing to recognize it as a consequence of the non-dimensionalist concept of spirit, which in itself secures indivisibility. The interpretive consequence for Newton is that there is no prima facie reason to suppose that the charitable interpretation takes him to deny holenmerism. (shrink)

This is a preprinted excerpt from: Kochiras, “By ye Divine Arm: God and Substance in De gravitatione”, Religious Studies (Sept. 2013), 49(3): 327-356 (available at: https://www.cambridge.org/core/journals/religious-studies/article/by-ye-divine-arm-god-and-substance -in-de-gravitatione/08D21B2C2611624FA11A0D6B115849AD ). In this preprinted excerpt, I explicate the concepts of matter and space that Newton develops in De gravitatione. As I interpret Newton’s account of created substances, bodies are constructed from qualities alone, as configured by God. Although regions of space and then “determined quantities of extension” appear to replace the Aristotelian substrate by functioning (...) as property-bearers, they actually serve only as logical subjects. An implication of the interpretation I develop is that only space is extended by having parts outside parts; material bodies are spatially extended only in a derivative sense, via the presence of their constitutive qualities or powers in space.

This paper presents a comparison of the philosophical systems of Francesco Patrizi and Henry More. The point, however, is not to demonstrate Patrizi’s influence on More but rather to see how, with respect to some particular subjects, they both tried to offer a modern interpretation of Neoplatonism. The main axis of the analysis follows the topics of space, light, and soul. While to More, light is of merely marginal interest, it is demonstrated that space and soul are of crucial importance (...) and play a similar role in both authors’ systems. They function as intermediary entities that link the higher and the lower reality and form a sort of canvas upon which the material world unfolds. Yet, in comparison with Patrizi, More’s system is both constrained by a much stricter, dualistic classification and at the same time veers dangerously close to immanentism and pantheism (which More tries to avoid).

In my paper, I dispute Christian Hengstermann’s analysis of More’s philosophical system as a form of panentheistic panpsychism in which matter is alive by virtue of being the last emanation from God. I show that, in his mature period, More explicitly rejected such an emanationist doctrine and attributed the non-mechanical powers of matter to an outside immaterial principle, the Spirit of Nature. Ultimately, this leads to a system in which divine space, the Spirit of Nature and the spirit of God (...) are representations of various aspects of the divine essence, as it is at work in the world. On the other hand, matter is not part of this triadic structure and can only be said to be alive at the cost of a rather counterintuitive redefinition of the notion of “life”. (shrink)

The following article consists of an introduction by the first author, an annotated translation by the second, and then an analysis by the first, of the earliest known Scandinavian response to the Vampire phenomenon of Medvedia in 1732 by Nicolaus Boye, a state-employed physician residing in Stockholm. The translation shows that Boye’s own article, which constitutes a complete refutation of Johann Flückinger’s claims, was meticulously organised, abstracting and arguing against the major themes which he observed in the Visum et Repertum, (...) while the analysis shows that Boye was working under the topical medical theories of the Dutch botanist and physician Herman Boerhaave. The analysis also demonstrates the extent to which Boye’s rationalism in refuting the Visum at Repertum is informed by his Lutheranism and belief in the Day of Judgement, and concludes by showing examples of the impact his work exerted on other academics in the 1730s.

According to the Cambridge Platonist Henry More, individual spirits--the souls of humans and non-human animals--are extended but cannot be physically divided. His contemporaries and recent commentators have charged that More has never given an explication of the grounds on which the indivisibility of spirits is based. In this article, I suggest that exploring the usage that More makes of the analogy between spirits and light could go some way towards providing such an explication. More compares the relation between spirit and (...) matter to the relation that, according to Aristotelian theories of light, holds between ?intentional species? and matter. I will argue that the purpose of his comparison is to highlight that both intentional species and spirits are existentially independent from matter. The existential independence of intentional species from matter expresses itself in the fact that light is not moved through the motion of the illuminated body. The existential independence of spirits from matter expresses itself in the fact that when a body that is coextensive with a spirit is divided, the spirit is not thereby divided but rather contracts into the remaining living organism.

One of the earliest refutations of the Visum et Repertum (1732) by Johann Flückinger was from Johann Wilhelm Nöbling, a young student of philosophy and theology at the University of Jena, who attacked the findings from a position of scientific scepticism enshrouded with Lutheran theology in his thesis Concerning the Blood-Sucking Corpses of those so-called Vampires or People-Suckers. While he is best remembered for first proposing the incubus or nightmare of sleep paralysis as being the real cause of the superstition, (...) his major contribution was theological, concerning the relation between body and soul. And yet while Nöbling provides a rigorous, scripture-based denial of vampirism, his framework necessarily accommodates contemporary medical theory, demonstrating both the adaptation of theology to science and the extent to which pneumatology still inhered in scientific enquiry.

RÉSUMÉ: Cet article examine les façons dont le platonicien de Cambridge Henry More, au XVIIe siècle, a tenté de défendre une rigoureuse séparation ontologique entre les substances matérielles et les substances spirituelles tout en maintenant que les unes et les autres étaient étendues. Nous élucidons certaines des théories et certains des concepts propres à More, tels que l’indiscerpabilité, la pénétrabilité, la spissitude essentielle et l’hylopathie, qui fournissaient, croyait-il, une base solide à cette séparation. Mais nous montrons aussi certaines faiblesses inhérentes (...) à ces théories, concluant en fin de compte que More n’est pas arrivé à maintenir la distinction stricte qu’il recherchait. (shrink)

ABSTRACTIn this paper, I explore Margaret Cavendish’s engagement with mid-seventeenth-century debates on spirits and spiritual activity in the world, especially the problems of incorporeal substance and magnetism. I argue that between 1664 and 1668, Cavendish developed an increasingly robust form of materialism in response to the deficiencies which she identified in alternative philosophical systems – principally mechanical philosophy and vitalism. This was an intriguing direction of travel, given the intensification in attacks on the supposedly atheistic materialism of Hobbes. While some (...) scholars claim that Cavendish’s views were not formed out of extensive engagement with contemporary thinkers, I suggest that, on the contrary, Cavendish engaged very closely with the views of More, Hobbes and others – including the vitalist thinker Johannes Baptista van Helmont and the mechanical philosopher Henry Power – on the subject of spirits and...
