This paper provides a systematic reconstruction of Cavendish's general epistemology and a characterization of the fundamental role of that theory in her natural philosophy. After reviewing the outlines of her natural philosophy, I describe her treatment of 'exterior knowledge', i.e. of perception in general and of sense perception in particular. I then describe her treatment of 'interior knowledge', i.e. of self-knowledge and 'conception'. I conclude by drawing out some implications of this reconstruction for our developing understanding of Cavendish's natural philosophy.

According to Margaret Cavendish the entire natural world is essentially rational such that everything thinks in some way or another. In this paper, I examine why Cavendish would believe that the natural world is ubiquitously rational, arguing against the usual account, which holds that she does so in order to account for the orderly production of very complex phenomena (e.g. living beings) given the limits of the mechanical philosophy. Rather, I argue, she attributes ubiquitous rationality to the natural world in (...) order to ground a theory of the ubiquitous freedom of nature, which in turn accounts for both the world's orderly and disorderly behavior.

Recent exciting work on Cavendish’s natural philosophy highlights the important role of motion in her system. But what is motion, according to Cavendish? I argue that motion, for Cavendish, is what I call ‘compositional motion’: for a body to be in motion is just for it to divide from some matter and join with other matter. So when Cavendish claims to reduce all natural change to motion, she is really reducing all natural change to mereological change. Cavendish also uses ‘motion’ (...) to name the power that matter has to set itself in compositional motion. That power is not reducible to local motion. If motion is not local motion and if motive power is not a function of actual motion, then despite her polemics, Cavendish does not reduce natural change to local motion. Instead, she offers a unique and exciting account of natural change. (shrink)

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.

Between 1653 and 1655 Margaret Cavendish makes a radical transition in her theory of matter, rejecting her earlier atomism in favour of an infinitely-extended and infinitely-divisible material plenum, with matter being ubiquitously self-moving, sensing, and rational. It is unclear, however, if Cavendish can actually dispense of atomism. One of her arguments against atomism, for example, depends upon the created world being harmonious and orderly, a premise Cavendish herself repeatedly undermines by noting nature’s many disorders. I argue that her supposed difficulties (...) with atomism expose a deeper tension in her work between two fundamental metaphysical commitments each of which has substantial philosophical support: her monist theory of the material world (which maintains that there exists just one natural substance which is the single principal cause) and her occasional theory of causation (which requires multiple finite principal causes in nature -- causes that might be considered individual substances). Her monism undermines atomism while her theory of occasional cause seems to rest on a conception of nature that would be especially friendly to atomism. I argue further that we can solve this tension within a Cavendishian framework in such a way as to preserve her theory of causation and her monism, but that this solution depends upon our taking her monism in a particular (and weak) form. I finally note that we can best make sense of her unique and interesting form of monism by acknowledging her social-political motivations in addition to her motivations in natural philosophy.

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.

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.

Margaret Cavendish was an English natural philosopher. Influenced by Hobbes and by ancient Stoicism, she held that the created, natural world is purely material; there are no incorporeal substances that causally affect the world in the course of nature. However, she parts company with Hobbes and sides with the Stoics in rejecting a participate theory of matter. Instead, she holds that matter is a continuum. She rejects the mechanical philosophy's account of the essence of matter as simply extension. For Cavendish, (...) matter is also essentially living, sensing, and rational. She also rejects the mechanical philosophy's explanation of change solely in terms of transference of motion. Her own explanation of change relies upon a notion of "occasional cause." This paper argues that Cavendish's occasional causes are not to be confused with those of Malebranche; hers have some efficient causal powers. It traces the concept of an occasional cause from the ancient Stoics, through Galen, to Renaissance natural philosophers such as J. B. van Helmont, and ultimately to Cavendish and to Descartes. Thus, the aim of the paper is to explicate Cavendish's non-mechanical model of natural change and to show how the key concept in this model, that of "occasional cause," has a long philosophical pedigree. L'anglaise Margaret Cavendish pratique la philosophic naturelle. Sous l'influence de Hobbes et du stoïcisme ancien, elle a soutenu que le monde naturel créé est purement matériel ; dans le cours de la nature, il n'y a pas de substances incorporelles qui affectent causalement le monde. Elle se sépare néanmoins de Hobbes et rejoint les Stoïciens dans son rejet d'une théorie de la matière particulaire. Elle considère au contraire que la matière est un continuum. Elle rejette l'explication de l'essence de la matière comme simple extension, fournie par la philosophic mécaniste. Pour Cavendish, la matière est de plus essentiellement vivante, sentante et rationnelle. Elle rejette aussi l'explication mécaniste du changement en simples termes de transmission de mouvement. Sa propre explication du changement s'appuie sur la notion de cause occasionnelle. Cet article defend l'idée que les causes occasionnelles de Cavendish ne doivent pas être confondues avec celles de Malebranche ; les siennes ont des pouvoirs causaux efficients. Il permet done de suivre l'histoire du concept de cause occasionnelle des anciens Stoïciens, en passant ensuite par Galien jusqu'aux Philosophes de la nature de la Renaissance, comme J. B. van Helmont, et finalement jusqu'à Cavendish et Descartes. Le but de cet article est ainsi de rendre explicite le modèle que Cavendish donne du changement naturel et de montrer comment le concept clé de ce modèle, celui de cause occasionnelle, est le produit d'une longue filiation philosophique.

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.

Margaret Cavendish was a philosopher, poet, scientist, novelist, and playwright of the seventeenth century. Her work is important for a number of reasons. It presents an early and compelling version of the naturalism that is found in current-day philosophy; it offers important insights that bear on recent discussions of the nature and characteristics of intelligence and the question of whether or not the bodies that surround us are intelligent or have an intelligent cause; it anticipates some of the central views (...) and arguments that are more commonly associated with figures like Thomas Hobbes and David Hume. This is the first full account of Cavendish’s philosophy and covers the whole span of her work. David Cunning begins with an overview of Cavendish’s life and work before assessing her contribution to a wide range of philosophical subjects, including her arguments concerning materialism, experimentation, the existence of God, social and political philosophy and free will and compatibilism. Setting Cavendish in both historical and philosophical context, he argues that like Spinoza she builds on central tenets of Descartes’ philosophy and develops them in a direction that Descartes himself would avoid. She defends a plenum metaphysics according to which all individuals are causally interdependent, and according to which the physical universe is a larger individual that constitutes all of reality. Cavendish is essential reading for students of seventeenth-century philosophy, early modern philosophy and seventeenth-century literature. (shrink)

The Well-Ordered Universe argues that Cavendish's natural philosophy, social and political philosophy, and medical theory share an underlying concern with order. This reveals interesting connections among Cavendish's natural philosophy and her views on gender, animals and the environment, and human health, and explains her commitment to monarchy and social hierarchy.

Lisa T. Sarasohn acutely examines the brilliant work of this untrained mind and explores the unorthodox development of her natural philosophy.
