For Margaret Cavendish, every single part of matter has self-knowledge, and almost every part has perceptive knowledge. This paper asks what is at stake for Cavendish in ascribing self-knowing and perceptive properties to matter. Whereas many commentators take perception and self-knowledge to be guides to Cavendish’s epistemology, this paper takes them to be guides to her metaphysics, in that it shows that these categories account for individual specificity and for relationality. A part of matter is a unique individual insofar as (...) it is self-knowing – and it is a part in relation to other parts, and to the whole of matter, insofar as it is a perceptive part. This is so because self-knowledge is purely self-referential and complete, while perceptive knowledge is purely relational. (shrink)

The nature of light is a focus of Thomas Hobbes’s natural philosophical project. Hobbes’s explanation of the light of lucid bodies differs across his works, from dilation and contraction in Elements of Law to simple circular motions in De corpore. However, Hobbes consistently explains perceived light by positing that bodily resistance generates the phantasm of light. In Letters I.XIX–XX of Philosophical Letters, fellow materialist Margaret Cavendish attacks the Hobbesian understanding of both lux and lumen by claiming that Hobbes has illicitly (...) made abstractions from matter. In this paper, I argue that Cavendish’s criticisms rely on an incorrect understanding of the nature of Hobbesian geometry and the role it plays in Hobbes’s natural philosophy. Rather than understanding geometry as wholly abstract, Hobbes attempts to ground geometry in different ways of considering bodies and their motions. Furthermore, Hobbes’s own criticisms of abstraction suggest that he would share many of the worries she raises but deny that he falls prey to them. (shrink)

In this paper, I offer a new interpretation of Margaret Cavendish’s remarks on beauty. According to it, Cavendish takes beauty to be a real, response-independent quality of objects. In this sense, Cavendish is an aesthetic realist. This position, which remains constant throughout her philosophical writings, contrasts with the non-realist views that were soon after to dominate philosophical reflections on matters of taste in the early modern period. It also, I argue, contrasts with the realism of Cavendish’s contemporary, Henry More. While (...) there are passages in Cavendish’s work that might seem to count against my reading—specifically, passages on disagreement in aesthetic judgement, on the power of beauty to elicit the passions, and on our inability to specify the nature of beauty—I show that, when situated against the background of Cavendish’s broader metaphysical and epistemological views, those passages in fact support the realist interpretation.

Henry More argues that materialism cannot account for cases where a single subject or perceiver has multiple perceptions simultaneously. Since we clearly do have multiple perceptions at the same time--for example, when we see, hear, and smell simultaneously--More concludes that we are not wholly material. In response to More's argument, Margaret Cavendish adopts a two-fold strategy. First, she argues that there is no general obstacle to mental unification in her version of materialism. Second, Cavendish appeals to the mind or rational (...) matter--terms she often uses interchangeably—to explain the integration of sensory input from multiple senses. When the mind integrates perceptions across modalities, the different parts of rational matter share their knowledge so that they all come to perceive alike. When rational parts successfully communicate their knowledge, each part knows what all the others know. They pool their knowledge; they perceive alike. Thus, when someone hears, sees, and tastes, each part of her mind hears, sees, and tastes alike, in parallel and in unison. The Cavendishian mind, in short, approximates simplicity by achieving uniformity or homogeneity of perceptions across its parts. (shrink)

Consider the distinctive qualitative property grass visually appears to have when it visually appears to be green. This property is an example of what I call sensuous color. Whereas early modern mechanists typically argue that bodies are not sensuously colored, Margaret Cavendish (1623–73) disagrees. In cases of veridical perception, she holds that grass is green in precisely the way it visually appears to be. In defense of her realist approach to sensuous colors, Cavendish argues that (i) it is impossible to (...) conceive of colorless bodies, (ii) the very possibility of color experience requires that bodies are sensuously colored, and (iii) the attribution of sensuous colors to bodies provides the best explanation of color constancy. Although some passages might suggest that Cavendish endorses a reductive account of sensuous color, according to which sensuous color reduces to a body's microscopic surface texture (or some other mechanistically respectable property), I argue that she accepts a nonreductive account, on which sensuous color is not thus reducible.

Many of Margaret Cavendish’s criticisms of Thomas Hobbes in the Philosophical Letters (1664) relate to the disorder and damage that she holds would result if Hobbesian pressure were the cause of visual perception. In this paper, I argue that her “two men” thought experiment in Letter IV is aimed at a different goal: to show the explanatory potency of her account. First, I connect Cavendish’s view of visual perception as “patterning” to the “two men” thought experiment in Letter IV. Second, (...) I provide a potential reply on Hobbes’s behalf that appeals to physiological differences between perceivers’ sense organs, drawing upon Hobbes’s optics in De homine. Third, I argue that such a reply would misunderstand Cavendish’s objective of showing the limited explanatory resources available in understanding visual perception as pressing when compared to her view of visual perception as patterning.

ABSTRACTThis paper discusses how early modern materialism can be defined and delineated, before turning to a brief survey of the main philosophical resources early modern materialist theories draw on. Subsequently, I discuss competing overall narratives concerning early modern materialism, and conclude with a defence of the controversial view that material soul theories belong to materialism proper.

Scholarly interest in Margaret Cavendish's philosophical views has steadily increased over the past decade, but her epistemology has received little attention, and no consensus has emerged; Cavendish has been characterized as a skeptic, as a rationalist, as presenting an alternative epistemology to both rationalism and empiricism, and even as presenting no clear theory of knowledge at all. This paper concludes that Cavendish was only a modest skeptic, for she believed that humans can achieve knowledge through sensitive and rational perception as (...) well as through self-knowledge and can form probable opinions through reasoning.

This paper considers Margaret Cavendish's distinctive anti-mechanist materialism, focusing on her 1664 Philosophical Letters, in which she discusses the views of Hobbes, Descartes, and More, among others. The paper examines Cavendish's views about natural, material souls: the soul of nature, the souls of finite individuals, and the relation between them. After briefly digressing to look at Cavendish's views about divine, supernatural souls, the paper then turns to the reasons for Cavendish's disagreement with mechanist accounts. There are disagreements over the explanation (...) of particular phenomena, but also a broader disagreement over what to take as one's most basic causal model. (shrink)

Margaret Cavendish is widely known as a materialist. However, since Cavendishian matter is always in motion, “matter” and “motion” are equally important foundational concepts for her natural philosophy. In Philosophical Letters (1664), she takes to task her materialist rival Thomas Hobbes by assaulting his account of accidents in general and his concept of “rest” in particular. In this article, I argue that Cavendish defends her continuous-motion view in two ways: first, she claims that her account avoids seeing accidents as capable (...) of generation and annihilation, which she argues is inconceivable; and second, she contends that according to Hobbes’s own view “rest” is an absurd conception since it cannot be drawn from experience. Beyond its function as a defense, I claim that Cavendish’s focused criticism of “rest” shows that she is a perceptive reader of Hobbes’s natural philosophy, insofar as her criticisms undercut the two a priori principles of Hobbesian physics. Finally, I show how her views developed in more detail in Philosophical and Physical Opinions (1663) and Observations upon Experimental Philosophy ([1666] 2001) avoid the worries she raises for Hobbesian materialism.

This paper pursues a question about the spatial relations between the three types of matter posited in Margaret Cavendish’s metaphysics. It examines the doctrine of complete blending and a distinctive argument against atomism, looking for grounds on which Cavendish can reject the existence of spatial regions composed of only one or two types of matter. It establishes, through that examination, that Cavendish operates with a causal conception of parts of nature and a dynamic notion of division. While the possibility of (...) unmixed spatial regions is found to be consistent with both the doctrine of complete blending and Cavendish’s anti-atomism by themselves, it is finally ruled out by a consideration of her theory of place. In fact, the geometrical question of the spatial relations between types of matter that drives the paper is ultimately exposed as illicitly mathematical from the perspective of Cavendish’s metaphysics.

This paper explores Thomas Hobbes’s account of animal life and mind. After a critical examination of Hobbes’s mechanistic explanation of operations of the mind such as perception and memory, I argue that his theory derives its strength from his idea of the dynamic interaction of the body with its surroundings. This dynamic interaction allows Hobbes to maintain that the purposive disposition of the animal is not merely an upshot of its material configuration, but an expression of its distinctive bodily history. (...) In support of Hobbes, I show how this is complemented by his account of the unity and continuity of the animal body in terms of a unification through the self-preserving drive that originates in perception. Nonetheless, I argue that Hobbes’s philosophy of animal life and mental faculties is hindered by a kind of epiphenomenalist perspective that is embedded in his materialist framework, and this perspective leaves the status of ideas and mental content unclear. I explain why Hobbes’s dynamic theory, founded upon the reciprocal determination of moving bodies, supports his idea of animal development and habituation while failing to account for the reflexivity of the mind.

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...

This essay explores an unstudied compendium to Margaret Cavendish’s 1655 Philosophical and Physical Opinions that was composed by the learned physician, plant anatomist, and secretary of the Royal Society, Nehemiah Grew. Despite the growing body of scholarship on Cavendish, minimal attention has been dedicated to her early reception. But studying this compendium provides some fascinating insights into how one of the foremost thinkers of her day read, emended, and manipulated her ideas. I propose that Grew turned to Cavendish’s work when (...) developing his substance theory in the years leading up to the publication of his 1682 The Anatomy of Plants, but that shifting intellectual tides led him to critique her version of material vitalism in his 1701 Cosmologia Sacra. Supported by a transcription of the compendium as an appendix, this article also sheds light on the role that early modern pedagogical techniques and memory tools played in shaping concepts of matter and mind.

This paper explores Cavendish’s argument for what she calls “animate matter.” Her commitment to the ubiquity of animate matter, styled “Cavendish’s animism,” is presented as the conclusion of an inference to the best explanation of nature’s order. The reconstruction of Cavendish’s argument begins with an examination of the relationship between God’s creation of our world and the order produced through nature’s wise governance of her parts. Cavendish’s materialism and anti-atomism are presented as ingredients in her final account of God’s ordering (...) of the world by making it a self-moving whole. On the present account of Cavendish’s metaphysics, this self-moving whole then freely produces the regular motions that constitute its ordering of itself, as a distinct ordering beyond God’s initial act of creating our world. The depth of Cavendish’s commitment to the animistic elements of her materialism—or in other words, the extent to which her system is genuinely animistic—is then considered. (shrink)
