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)

Margaret Cavendish was a philosopher and writer active in mid-seventeenth century England. She is important not just as one of the first women active in philosophy in early modern age but as the expounder of an original scientific theory based on vitalism and materialism, by which she rejected the mechanical philosophy of Descartes and Hobbes and the experimental philosophy of Boyle and Hooke. Also, while not developing a theory of gender equality, she envisaged a form of emancipation of women based (...) on intellectual activity as a way to social recognition and to the exercise of influence on society and politics.

Perception plays a central and wide-ranging role in the philosophy of Margaret Cavendish. In this paper, I argue that Cavendish holds a naïve realist theory of perception. The case draws on what Cavendish has to say about perceptual presentation, the role of sympathy in experience, the natures of hallucination and of illusion, and the individuation of kinds. While Cavendish takes perception to have representational content, I explain how this is consistent with naïve realism. In closing, I address challenges to the (...) interpretation, one of which turns on whether Cavendish allows for action at a distance. I argue that she does. (shrink)

Margaret Cavendish’s views about the nature of bodies and perception leave her with a potentially problematic implication: that light has no role in visual perception. For her, perception occurs through the self-motion of animate matter, not through a mechanical system that appeals to local motions and collisions of contiguous bodies. This means that motion is not transferred from external objects with light playing a mediating role; the matter of our eyes simply moves itself to copy the sensible qualities of external (...) bodies. However, Cavendish cannot ignore the simple empirical fact that we appear to have visual perceptions in the presence of light but not in the presence of darkness. Light must play some role. I argue that light for Cavendish plays an intermediary role but does not transfer motions as the mechanical model suggests. Rather, light behaves like our eyes by moving itself to form copies of external objects. Our eyes then see these copies. For Cavendish, we are directly acquainted with a “veil of light” rather than the objects themselves. (shrink)

Seventeenth-century philosopher Margaret Cavendish wrote not only several philosophical treatises, but also many fictional works. I argue for taking the latter as serious objects of study for historians of philosophy, and sketch a method for doing so. Cavendish's fiction is full of conflicting viewpoints, and many authors have argued that this demonstrates that she did not intend her literary works to serve serious philosophical purpose. But if we consider philosophers more central to the canon, such as Plato or Kierkegaard, who (...) sometimes used literary forms to do serious philosophy, we see that these arguments are unfounded. Like those philosophers, Cavendish had several philosophical motivations for pursuing value-theoretic issues through the flexible formats of literary genres. This suggests that Cavendish's literary corpus may be fruitful and largely unexplored ground for the history of philosophy. (shrink)

The empress of Margaret Cavendish’s The Blazing World dismisses pure mathematicians as a waste of her time, and declares of the applied mathematicians that “there [is] neither Truth nor Justice in their Profession”. In Cavendish’s theoretical work, she defends the Empress’ judgments. In this paper, I discuss Cavendish’s arguments against pure and applied mathematics. In Sect. 3, I develop an interpretation of some relevant parts of Cavendish’s metaphysics and epistemology, focusing on her anti-abstractionism and what I call her ’assimilation’ view (...) of knowledge. In Sects. 4 and 5, I use this to develop Cavendish’s critiques of pure and applied mathematics, respectively. These critiques center on the claims that mathematics purports to describe non-beings, that nature is infinitely and irreducibly complex, and, perhaps most originally, that mathematical thinking deforms the subject of representation, not just the object.

In this paper, I develop a new interpretation of the order of nature, its function, and its implications in Margaret Cavendish’s philosophy. According to the infinite balance account, the order of nature consists in a balance among the infinite varieties of nature. That is, for Cavendish, nature contains an infinity of different types of matter: infinite species, shapes, and motions. The potential tumult implicated by such a variety, however, is tempered by the counterbalancing of the different kinds and motions of (...) matter against one another, or what Cavendish calls the “poising” of nature’s actions by their opposites. The infinite balance account of order offers insight into a central notion of Cavendish’s system and bears important implications for other interpretive issues. To wit, the account resolves the standing issue of whether there is genuine disorder in Cavendish’s universe and elucidates the nature of her opposition to atomism. Nevertheless, the interpretation faces an epistemic challenge, insofar as Cavendish appears to deny knowledge of infinity. I argue that, for Cavendish, our knowledge of the order of nature is conceptual and non-empirical, revealing limits to her apparent empiricism. (shrink)

Este artículo analiza la posición de Margaret Cavendish sobre la realidad y la ficción en los sueños y su papel dentro del escepticismo moderado de su filosofía. Cavendish sostiene que no hay distinción entre las representaciones que se tienen en los sueños y en la vigilia, no considera que la diferencia entre la realidad y la ficción sea tajante o relevante; de modo que, si bien promueve un discurso filosófico que articula la razón que busca conocer la realidad y la (...) fantasía (fancy) que construye ficciones, considera que solo las fantasías poéticas “elevadas” son competentes para la con-strucción de este discurso.

It has often been noted that Margaret Cavendish discusses God in her writings on natural philosophy far more than one might think she ought to given her explicit claim that a study of God belongs to theology which is to be kept strictly separate from studies in natural philosophy. In this article, I examine one way in which God enters substantially into her natural philosophy, namely the role he plays in her particular version of teleology. I conclude that, while Cavendish (...) has some resources with which to partially alleviate this tension, she is nonetheless left with a significant difficulty. (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.

Nos proponemos estudiar las objeciones de Cavendish hacia la filosofía experimental desde una perspectiva no dicotómica para mostrar que, lejos de establecer un enfrentamiento entre la filosofía contemplativa y la experimental, la razón y la sensación, o la naturaleza y el arte, la autora plantea una cooperación organizada entre estos aspectos. La postura de Cavendish puede comprenderse adecuadamente si se tiene en cuenta que su epistemología se arraiga en su metafísica, en la que los grados de la materia y los (...) distintos seres vivos que conforman el universo ocupan un lugar determinado y cumplen cierta función conformando una totalidad orgánica y armónica.

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 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.

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.

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.

Margaret Cavendish (1623-1673) argues that when someone throws a ball, their hand does not cause the ball to move. Instead, the ball moves itself. In this chapter, I reconstruct Cavendish’s argument that material things—like the ball—are self-moving. Cavendish argues that body-body interaction is unintelligible. We cannot make sense of interaction in terms of the transfer of motion nor the more basic idea that one body acts in another body. Assuming something moves bodies around, Cavendish concludes that bodies move themselves. Still, (...) Cavendish needs to explain why bodies appear to causally interact even if they do not really. Balls do not usually throw themselves without a helping hand. I offer a new reading of the way bodies respond to their external circumstances in terms of prerequisites or enabling conditions.

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.

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)

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)
