Margaret Cavendish (1623—1673)

Margaret Lucas Cavendish, the Duchess of Newcastle, was a philosopher, poet, playwright and essayist. Her philosophical writings were concerned mostly with issues of metaphysics and natural philosophy, but also extended to social and political concerns. Like Hobbes and Descartes, she rejected what she took to be the occult explanations of the Scholastics. Against Descartes, however, she rejected dualism and incorporeal substance of any kind. Against Hobbes, on the other hand, she argued for a vitalist materialism, according to which all things in nature were composed of self-moving, animate matter. Specifically, she argued that the variety and orderliness of natural phenomena cannot be explained by blind mechanism and atomism, but instead require the parts of nature to move themselves in regular ways, according to their distinctive motions. And in order to explain that, she argued for panpsychism, the view that all things in nature possess minds or mental properties. Indeed, she even argued that all bodies, including tables and chairs, as well as parts of the bodies of organisms, such as the human heart or liver, know their own distinctive motions and are thereby able to carry it out. These different parts of nature, each knowing and executing their distinctive motions, create and explain the harmonious and varied order of it. In several ways, Cavendish can be seen as one of the first philosophers to take up several interesting positions against the mechanism of the modern scientific worldview of her time. Thus it is possible to add that she presages thinkers such as Spinoza and Leibniz.

When she turned to discuss political and social issues, Cavendish’s metaphysical commitments seem to remain. Cavendish was a staunch royalist and aristocrat; perhaps not surprisingly, then, she argued that each person in society has a particular place and distinctive activity and that, furthermore, social harmony only arises when people know their proper places and perform their defining actions. She was therefore critical of social mobility and unfettered political liberty, seeing them as a threat to the order and harmony of the state. Even so, her writings also contain nuanced and complex discussions of gender and religion, among a variety of other topics.

Despite her conservative political tendencies, Cavendish herself can be seen as a model for later women writers. She wrote dozens of books, at least five of which alone were on natural philosophy, under her own name, a feat which may make her the most published female author of the seventeenth century and one of the most prolific women philosophers in the early modern period. In addition to writing much on natural philosophy, she wrote on a dizzying array of other topics and, perhaps most impressively, in a wide range of genres. Her philosophically informed poetry, plays, letters and essays are at times as philosophically valuable as her treatises of natural philosophy.

1. Life and Works

Margaret Lucas was born in 1623 in Colchester into a family of aristocrats and staunch royalists. She received little formal education, being tutored at home with her seven siblings, of which she was the youngest. She reports having spent much time in conversation with one of her brothers, John, who considered himself a scholar and who would become a founding member of the Royal Society. She joined the Queen’s court and served as a maid to Queen Henrietta Maria, following her into exile in 1644, during the English Civil War. While in exile she met William Cavendish, then Marquess and later Duke of Newcastle. They were married in 1645.

While in exile in Paris and Antwerp, she reports discussing philosophy and natural science with her husband and his younger brother, Sir Charles Cavendish, who held a regular salon attended by Thomas Hobbes, Kenelm Digby and occasionally René Descartes, Marin Mersenne and Pierre Gassendi. Margaret herself reports having attended several dinners, at which these philosophers were present, though she denies having spoken to them about any, but the most superficial of matters.

While her husband remained in exile, she returned in 1651 and again in 1653 to England. This was during the reign of Commonwealth, during which her husband, were he to have returned, would have had to renounce his royalism and swear fealty to the Commonwealth, as was required by the republican parliament of the time. The parliament did not extend that requirement to women, claiming that women were not capable of such political acts. Thus Margaret was allowed to return to England without swearing fealty to the Commonwealth.

During her 1653 visit, she arranged for the publication of her first collection of writings, Poems and Fancies and Philosophical Fancies. She reports having delivered the second philosophical treatise a few days too late to have it included with the first in a single publication, which had been her original intention. The publisher was Martin and Allestyre, at the Bell in St. Paul’s Churchyard, which was a well-regarded publisher, who later became the official publisher for the Royal Society. It is truly remarkable that she was able to secure their publication, as few women published philosophy in England in the seventeenth century, much less under their own name and while in exile.

The same publishing house would publish The World’s Olio and Philosophical and Physical Opinions in 1655 and Nature’s Pictures in 1656. The second work of 1655, Philosophical and Physical Opinions, contained five parts and 210 chapters, the first part of which, consisting of 58 chapters, was in fact a reprinting of her earlier Philosophical Fancies. With her 1655 Philosophical and Physical Opinions, she added a number of epistles and her “Condemning Treatise on Atoms” to the front matter and also extended the work beyond the earlier Philosophical Fancies significantly.

With the Restoration of Charles II to the throne, she returned to England with her husband and continued to write. In addition to publishing on natural philosophy, she also wrote essays on a remarkable variety of other topics, including the nature of poetry, the proper way to hold a feast, fame, women’s roles in society and many others. She also wrote many plays and poems, as well as a fantastic utopia, The Description of a New World, Called the Blazing World in 1668.

There may have been some controversy over a woman publishing works on natural philosophy, as she felt the need to include several epistles, both from herself and from her husband and brother-in-law, attesting to the fact that she had written these works herself. Indeed, she returns to defend herself as an author and natural philosopher at a number of different places in her work, often in epistles to the reader. She also defends the propriety of her being so bold as to write in her own name and to think her thoughts worthy of publication. Her several discussions of fame are worth noting in this context.

She continued to write on natural philosophy, among other topics, to growing attention. She sent her works to many of the well-known philosophers then operating in England, as well as to the faculties at Cambridge and Oxford.  Indeed, after she had published her most famous work of natural philosophy, Observations Upon Experimental Philosophy in 1666, she was invited to attend a meeting of the Royal Society, a privilege rarely granted to women at the time.

In all, she may be the most prolific woman writer of early modern Europe and certainly the most prolific woman philosopher. Depending on how one counts, she published over a dozen and perhaps as many as twenty works, at least five of which are works on natural philosophy and many more contain essays with substantive philosophical content.

2. Natural Philosophy

Cavendish wrote half a dozen of works on natural philosophy. Indeed, natural philosophy constituted the largest part of her philosophical output and a large part of her writing as a whole. Her philosophical commitments can be described as materialist, vitalist and panpsychist. In what follows, her philosophical discussions will be grouped around several recurring themes and arguments.

a. Materialism

Like Hobbes, Descartes or Bacon, Cavendish regularly motivates her position by attacking the Aristotelianism of the schools, mocking those whom her husband calls the “gown-tribe.” She criticized what she took to be their commitment to occult powers and incorporeal beings in nature and offers her materialism as an alternative. She explains that her intent is to provide a philosophical system accessible to all, without special training. From her earliest work, Philosophical Fancies, published in 1653, Cavendish argued for materialism in nature. In the first two chapters of that work, which she reprinted in Philosophical and Physical Opinions in 1655, she claims that nature is one infinite material thing, which she sometimes describes as “the substance of infinite matter” (“Condemning Treatise of Atomes”). This infinite material substance is composed of an infinite number of material parts, with infinite degrees of motion. Similarly, this motion is all of the same kind, differing from instance to instance only in swiftness or direction. In other words, the natural world is entirely constituted by a single type of stuff, which she calls matter and a single force, which she calls motion. She distinguishes the objects and events in nature from one another by the varying parts of matter, bearing different motions, within that one infinite material substance. She explicitly extends this materialist doctrine to the human mind in chapter 2 of the Philosophical Fancies, where she says that the forms of the gown-tribe, as well as human minds, are nothing but “matter moving, or matter moved.” Furthermore, she remained committed to this materialism throughout her career, such as in her Observations Upon Experimental Philosophy first published in 1666, claiming that all actions of sense or of reason are corporeal. Thus we see from the very beginning of her first work that she is a materialist.

The exact nature of her materialism develops over time, however. In her earliest work from 1653, she allows for an atomist account of nature and matter, though by 1656 she is already arguing against atomism in her “Condemning Treatise of Atomes”. Later, in her Observations from 1666, she provides at least two arguments against atomism. First, she argues that the concept of an extended yet indivisible body is incoherent, saying, “whatsoever has body, or is material, has quantity; and what has quantity, is divisible” (Ch. 31, 125); this is an argument that was commonly employed against atomism in the seventeenth century. She also argues that composite bodies, each with their own motions, could not account for the unity of the complex body, but would instead be like a swarm of bees or a school of fish. Atomism, she argues, cannot explain organic unity. She says, “[w]herefore, if there should be a composition of atoms, it would not be a body made of parts, but of so many whole and entire single bodies, meeting together as a swarm of bees...and the concourse of them would rather cause a confusion, than a conformity in nature” (Ch. 31, 129). Instead of atomism, Cavendish proposes that matter is both infinite in extension and always further divisible. Furthermore, for Cavendish, complex beings such as animals are composed of distinctive matter in motion, which she takes to provide them with their unity. Even so, her primary targets are not atomist materialism, as much as both the occultism of the Schools and the mechanism of some of her contemporaries.

She also applies her materialism to the human mind. In her early works, she suggests that there is nothing of the human being that is not material. For example, in her first work, she wrote a brief dialogue between body and mind, in which she claims that the only way the mind can attain any sort of life after the death of the body is by fame, that is, by being thought well of by others. Indeed, she elsewhere claims that "all the actions of sense and reason...are corporeal” and “sense and reason are the same in all creatures and all parts of nature” (Ch. 31, 128), as well as, “knowledge, being material, consists of parts” (Ch. 37, 160).

Cavendish seems to qualify her materialism with regard to the human soul later in her career, when she clarifies that her previously strong and consistent commitment to materialism only applies to the natural world. For example, in Observations, she claims that humans have both a material mind and, in addition, a supernatural, immaterial soul. She argues that the way, in which this supernatural soul is related to the material mind and body is itself supernatural. After all, she suggests, place is a property belonging only to bodies and thus, could not belong to an immaterial soul. Therefore, the way, in which the immaterial soul is related to the material person is itself a supernatural, that is, miraculous phenomenon. Unfortunately, she offers little explanation for this immaterial soul and refrains from explaining whether or how the immortal soul might interact at all with anything in nature, instead implying that it does not. To make matters even more confusing, she seems to amend her view in 1668 when claiming that only God is immaterial and all other things are material. It may be that she had changed her mind as to whether or not human beings have immaterial, supernatural souls, but the texts themselves do not seem to speak definitively.

Throughout her work, however, Cavendish did claim that human beings possess a material soul. She explains the material, natural soul in the same way, in which she explains the mind, through her distinction among the different degrees of motion in matter, as mentioned above. Briefly, she claims that matter may have differing degrees of motion, such that some matter is relatively inert and gross, that is, being composed of larger pieces of matter, which she sometimes calls “dull matter”. In contrast, there is also a finer and more rare matter, which possesses more motion. This faster and lighter matter infuses dull matter. The natural, material, human soul or mind, she explains, is the finer, rarer matter within our grosser, cruder material bodies. Scholars have noted the similarity this view bears to Stoic doctrine, in that the rarer, more quickly moving matter resembles the Stoic pneuma.

Just like the Stoics, she also explicitly states in her later works—and suggests at times in her earlier works—that all bodies are completely infused with varying degrees of this active matter. Indeed, it is this matter that accounts for the regularity of natural phenomena across all of nature. She says that “there can be no order, method or harmony, especially such as appears in the actions of nature, without there be reason to cause that order and harmony” (Ch 6, 207). She claims, for example, that animals possess motions visible externally, such as jumping or running, whereas vegetables and minerals possess and exhibit motions only detectable internally, such as contracting or dilating. She refers to the motions found in animals, vegetables and minerals to varying degrees as sensitive spirits, a term that calls to mind Descartes’ animal spirits. But even minerals and vegetables and also animals and humans possess a further, yet finer and more quickly moving form of matter, which she calls “rational spirits.” These rational spirits are the quickly moving, but rare pneuma-like matter described above, which ultimately explain the various motions and behaviors of the natural objects. Ultimately, though, these motions and the matter they infuse are of the same fundamental kind, differing only in their degree of motion. This view, coupled with her radical claims that “all motion is life” and “knowledge is motion” will lead to her vitalism and panpsychism.

Another of Cavendish’s distinctive commitments about the nature of matter is this: matter bears an infinite degree of motion and, crucially, it bears that motion eternally. In other words, if a bit of matter has a certain degree of motion, according to Cavendish, it cannot lose that degree of motion nor communicate it to another piece of matter. We might say that, for Cavendish, the particular degree of motion that a part of matter bears is essential to that part. Thus, the cruder and grosser matter that bears a lesser degree of matter does so by its nature and cannot lose or gain a degree of motion. Similarly, the more quickly moving, finer parts of matter also bear their greater degree of motion by nature and cannot gain, lose or communicate the motion either. This view is related to another major theme of Cavendish’s work, one that we might call vitalism.

b. Vitalism and the Variability Argument

In addition to her commitment to materialism, Cavendish took pains to reject a position that was often associated with materialism in the seventeenth century, namely that of mechanism. Mechanism can be understood as the view that the natural world, as well as human beings, are made up of uniform material components that interact according to laws of motion and collision. One statement of this view, with which Cavendish was familiar, can be found in the opening chapters of Thomas Hobbes’ Leviathan. René Descartes, too, provided a mechanistic account of the natural world—apart from his commitment to the existence of the immaterial souls of human beings, of course.

Cavendish argued that mechanism could not be an accurate account of the natural world, because it could not properly explain the world that we observe. She claimed that two notable features of the natural world are variety and orderliness. The world around us is full of a vast array of different sorts of creatures and things, each performing distinctive activities or bearing distinct properties. Despite the natural world’s plentitude, it was also orderly. If we understand the nature of a particular creature or substance, we could predict successfully how it might behave or react to certain stimuli. Cavendish reasoned that if the world was ultimately constituted by uniform matter, passively receiving and transferring motion, according to mathematical laws of collision, then the universe should be either entirely homogenous or entirely chaotic. In other words, if passive, uniform matter communicating motion was really all we had to explain nature, we would not be able to account for its variety and orderliness—it would lack one or the other.

Instead, she claimed, different parts of the infinite material substance bear different degrees of motion by nature. They cannot directly transfer motion from one body to another, since motion is a property of the body that possesses it and not as something that can exist apart from its body. Thus individual bodies cannot give or receive their motions. Hence, the phenomena we observe are not to be explained by reference to uniform pieces of matter exchanging motion via collision. Rather, she explains, what we see is like a dance, in which each body moves according to its own, distinctive, internal principle, such that a pattern might be created by the dancers on the dance floor. She explicitly offers this dance metaphor in her first work of 1653 and again in 1655. For example, when she explains perception, she claims that the rational spirits flow in and out of the body through the eyes and touch upon the object being perceived, intermixing with the rational spirits found therein. The object, possessing its own distinctive spirits and motions, dances a pattern before the rational spirits, which flow back into the eyes.  These rational spirits then take up the dance themselves, flowing back into the brain and continuing the dance, which she takes to be sufficient for the mind’s perceiving the object in virtue of the mind’s containing the distinctive dance or pattern. In these early works, she further explains that the rational spirits copy these dances based on a “natural sympathy” among adjacent bodies, particularly between the rational spirits of the perceiver and object perceived. Note that, throughout this account of perception, motion is never transferred from one body to another. Instead, motions and “dances” are taken up from the internal activity of the rational spirits, that is, from the nature of the moving matter. The matter moves itself according to its own nature and initiates changes in its own motion via natural sympathy.

By the 1660s, though, she largely replaces the dance metaphor with the terms “imitation” and “figuring out”, the latter in the sense of tracing or copying a shape or distinctive pattern of motion. Even so, the account is largely the same. Her argument from the Observations could be reconstructed as follows:

  1. Bodies move in orderly and infinitely variable ways.
  2. Either they are moved by spirits or they are moved by bodies.
  3. But not spirits because that is mysterious, so bodies.
  4. If bodily motion issues from the body, then, it must issue from either inanimate matter (mechanism) or animate matter (vitalism).
  5. But not inanimate matter (mechanism), for the mechanistic account of bodily motion, (such as animals spirits and inanimate fine particles that transmit force), cannot account for the infinite variety and orderliness of the activity in nature.
  6. So the bodily cause of motion must be the body’s animate matter, which (it is alleged) has an ability to produce an infinite variety of orderly effects.

This is what might be called the argument from the variability and regularity of nature for self-moving matter. Premise 5 implies the argument that if the world was ultimately constituted by uniform matter, passively receiving and transferring motion, according to mathematical laws of collision, then the universe should be either entirely homogenous or entirely chaotic. In this argument for self-moving matter, many of the central themes of Cavendish’s natural philosophy are visible: her materialist rejection of incorporeal causes, her denial of mechanistic explanation and her resulting vitalism.

Another significant feature of her natural philosophy, and one that appears especially clearly when she critiques mechanism, is her refusal to take mathematical physics as an exemplar. Whereas Cartesian and Hobbesian natural philosophy could be described as attempts to understand nature with metaphors and modes of explanation taken from the new, mathematical physics, Cavendish instead draws from other sources, especially her personal experiences with country life and, less directly, the life sciences. When explaining natural phenomena, she often makes reference to the behaviors of animals and humans, as well as her awareness of botanical phenomena. She in fact reported in the 1650s that Gerald’s Herbal, a botanical reference book, was the only scientific work she had read. Perhaps because of this, she often explained the behaviors of an animal’s or plant’s rational spirits in terms of their macro-level behaviors, rather than in terms of atomic or corpuscular, mathematical explanation. By the 1660s, at least, we know that she had read and engaged the work of other vitalist and anti-mechanists, such as the alchemist Johannes Baptista Van Helmont. However, even before that time, her preference for biological metaphors over those of mathematical physics was evident.

Cavendish’s preference for biological modes of explanation can also be seen in her organicism. Not only does she deny atomism, but she also argues that the parts of bodies in part possess their distinctive motions and natures in virtue of the larger, organic systems, in which they are located. She says, “[f]or example: an eye, although it be composed of parts, and has a whole and perfect figure, yet it is but part of the head, and could not subsist without it” (Observations, Ch. 31). This is not an argument for organicism; instead, she means it as an analogy to illustrate her views on individuals more generally.

Despite the similarities of her vitalism to that of Van Helmont or perhaps Henry More, Cavendish also departs from them in her commitment to materialism. Indeed, she accounts for life in nature by claiming that “[a]ll motion is life,” even in her first work of 1653. Human beings are alive, she says, because they are material beings composed of matter with varying degrees of motion moving in a distinctive pattern. For Cavendish that is all that is needed for something to be alive. Note, though, that all things in nature, from humans and animals and plants down to minerals and artifacts, are the things they are, because they are composed of matter with distinctive patterns and degrees of motion. In this regard, she resembles Hobbes, even though she will ultimately reject his mechanistic view of matter, especially with her view that all matter is self-moving. We might therefore say that Cavendish’s natural philosophy is committed to pan-vitalism or animism, or even, as Cudworth would later say, hylozoism. But we must remember that her view departs from the Cambridge Platonists and Van Helmont in denying that the principles of life are to be explained by reference to incorporeal powers, entities or properties. All matter is to some extent alive and all of nature is infused with a principle of life, but this principle of life is simply motion.

Thus Cavendish provides a fairly deflationary account of life as motion and in this regard her natural philosophy may resemble Hobbes or Descartes. Despite this similarity, Cavendish again rejects their mechanism in her denial of determinism, even with regards to bodily interaction. Though she often appeals to the orderliness and regularity of nature in defending her theory of self-moving matter, she also recognizes the presence of disorder in nature, such as in disease. In fact, she explains illness or disease as the rebellion of a part of the body against the whole, explaining that some bits of matter have freely chosen alternative motions and thus disrupted the harmonious all. In short, Cavendish ascribes a libertarian freedom not only to human agents but even to the parts of matter themselves, explaining the behaviors of organisms with a social ‘body politic’ metaphor. We might say, then, that she draws from experiences of the biological and botanical world to explain her metaphysics, but she also incorporates a Hobbesian sense of the body politic into her metaphysics and in so doing reinforces her rejection of the mechanistic worldview.

However, Cavendish does not stop at explaining the principle of life by reference to degrees of motion in matter, because she also claims to explain mental representation and ultimately knowledge in this way. When a particular pattern of motion occurs in the brain, say, via perception, the person perceives the object; for the person to have an idea of the object is just for her brain to contain its distinctive motion. More generally, she takes the presence of such patterned motions in matter to mean that said matter has knowledge, at least in some sense. Yet she also argues that such motions can be found throughout all of nature, every body possessing its own distinctive motions. For these reasons, her vitalist materialism fits nicely with her panpsychism.

c. Panpsychism

In saying that all motion is life and that all things in nature are composed of matter with a degree of motion, Cavendish affirms that life permeates all of the natural world, including what we might call inanimate objects. For Cavendish, inanimate objects are alive, because they possess motion, though they might have a lesser degree of motion, and thus a lesser degree of life, than an animal or human being. Indeed, she also believes that knowledge is similarly diffused across all of nature to greater and lesser degrees. For these reasons, we might call Cavendish an incremental naturalist with regard to knowledge and life. That is, she takes distinctively human traits such as knowledge and life to be natural properties that are present to varying degrees throughout all of nature.

Throughout her work, Cavendish argues that whatever has motion has knowledge and that knowledge is innate or internally directed motion. In her Philosophical Fancies of 1653, she explains that

the touch of the heel, or any part of the body else, is the like motion, as the thought thereof in the head; the one is the motion of the sensitive spirits, the other in the rational spirits, as touch from the sensitive spirits, for thought is only a strong touch, and touch a weak thought. So sense is a weak knowledge, and knowledge a strong sense, made by the degrees of the spirits (Chapter 45).

In the next chapter she continues to argue that all matter exhibits regular motion, which occurs because all matter is infused with sensitive spirits; but to have sensitive spirits is to be able to sense; thus all matter senses things.

Now, in her earliest work, she offers at best a “who knows so why not” sort of argument that matter thinks, saying, “[i]f so, who knows, but vegetables and minerals may have some of those rational spirits, which is a mind or soul in them, as well as man?" and “if their [vegetables and minerals] knowledge be not the same knowledge, but different from the knowledge of animals, by reason of their different figures, made by other kind of motion on other tempered matter, yet it is knowledge” (Chapter 46).

Later, for example in her Observations, she argues that the regularity of nature can best—or perhaps only—be explained by admitting that all material bodies possess knowledge. She argues that matter and material beings exhibit regular motion and then argues that “there can be no regular motion without knowledge, sense, and reason” (Observations, 129). Furhtermore, she argues that each part of the body and each object in nature exhibits a distinctive activity. The brain thinks; the stomach digests; the loins produce offspring—and they do so in regular and consistent ways. Indeed, each of these organs or parts of the body are themselves also composite, made up of an infinite number of smaller bodies. What unites them, however, is their distinctive motions, producing their distinctive behaviors. And Cavendish takes each of these distinctive motions to be a kind of knowledge.

She argues that we ought to think of these distinctive motions as knowledge, because that is the best, or perhaps only, way to explain the regularity and stability of these composites. If these parts are to do these things, they must know what they do, especially given the regular and consistent ways in which they do them. Indeed, without matter knowing its own distinctive motions, she argues, perception would be impossible. She says, “[s]elf-knowledge is the ground, or fundamental cause of perception: for were there not self-knowledge, there could not be perception” (Observations, 155). In short, all material entities, which is to say all things in nature, possess knowledge. The view that all things in nature possess mind or mental properties is panpsychism, to which Cavendish is committed here.

Even so, she uses the concept of knowledge in an unusual way. When she ascribes knowledge to a rock, or to my liver for example, but she neither necessarily means that the rock or my liver have mental states like ours nor that they can perceive their environments in the same way we do. For Cavendish, the knowledge of a thing like a mirror is, indeed, conditioned by the sort of motions that constitute the mirror, the motions that make it the thing it is; as such, mirror-knowledge and mirror-perception are very different from their human analogues. Even so, the mirror’s perception and knowledge are in some ways analogous to human perception and knowledge; both involve the object’s patterning out its own matter in a way, which copies or resembles an external object. Despite this similarity between a mirror and a human, the human being is composed of matter capable of many different kinds of perception and knowledge, whereas the mirror has a very limited ability to pattern out or reflect its environment. And the human has sufficient amounts of rational spirits uniting its parts to be able to conduct rational inquiry, whereas the rational matter of a mirror is very limited indeed.

This might sound as though she is walking back her commitment to panpsychism, but in fact she is not. For these parts or degrees of matter that possess varying levels of awareness are in fact entirely intermixed together in all things. She says, “there is a double perception in all parts of nature, to wit, rational and sensitive.... I believe there is sense and reason, or sensitive and rational knowledge, not only in all creatures, but in every part of every particular creature” (Ch. 36). Thus the rock, though it possesses a great deal of duller matter, also possesses sensitive and even rational spirits within. So Cavendish says,

self-motion is the cause of all the various...actions of nature; these cannot be performed without perception: for all actions are knowing and perceptive; and, were there no perceptions, there could not possibly be any such actions: for, how should parts agree, either in generation, composition, or dissolution of composed figures, if they had no knowledge or perception of each other? (Ch. 37, 167).

In short, Cavendish’s natural philosophy is materialist, vitalist and panpsychist, as well as anti-atomist and anti-mechanist. Unlike many of her opponents who favor mathematical physics, she takes the living things—and the limited awareness of the life sciences—as a model for her natural philosophy, as evidenced in her organicism, as well as her particular use of metaphor. In other words, she agrees with Descartes and Hobbes against the occult explanations of the Scholastics, with More and Van Helmont against the reductive mechanism of Hobbes and Descartes and with Hobbes and Stoic materialism against the incorporeal principles of More and Van Helmont.

d. God

Cavendish’s views on God are puzzling. She regularly repeats that we cannot assert the existence of things that are not observable material objects in the natural world and she does so in a way that might suggest to the modern reader that she does not believe in the immortality of the soul or the existence of an immaterial God. This would likely be a mistake, however, as there are several passages where she instead explains that she does not include God in her speculations, because we cannot speak with any degree of confidence about God’s nature. Though God is mostly absent from her work in the 1650s, in the Observations she says, “there is an infinite difference between divine attributes, and natural properties; wherefore to similize [sic] our reason, will, understanding, faculties, passions and figures etc. to God, is too high a presumption, and in some manner a blasphemy” (“Further Observations”, Ch 10, 215) and “God is incomprehensible, and above nature: but inasmuch as can be known, to wit, his being [i.e., that he exists]; and that he all-powerful...eternal, infinite, omnipotent, incorporeal, individual, immovable being” (*Further Observations*, Ch 11, 216-17). This certainly suggests that she takes God to exist or, at least, that she takes questions of his existence and nature to lie largely outside of the realm of natural philosophy and instead, perhaps, to be a matter of faith alone.

Nevertheless, we might speculate on the details of her views. As mentioned above, her views on the existence of a supernatural soul seem to be in tension with her other metaphysical commitments.  Similarly, her views on the existence of an immaterial God seem similarly in tension. Interestingly, she attaches an erratum on the final page of her first work, Philosophical Fancies, apologizing to the reader for having omitted the appropriate pieties and references to God in her natural philosophical system. What is even stranger is that, when she would reprint and re-write that system in her 1656 Philosophical and Physical Opinions, she would again omit any references to God and instead include the same erratum a second time.

Even so, it is unlikely she thought of herself as an atheist. Perhaps, as some scholars have interpreted Thomas Hobbes, she simply believed that she had no business discussing the nature of God’s existence as that was not a matter of rational inquiry but mere faith. It should be noted, however, that her several discussions of fame suggest that she was not convinced that she would have an existence after her own death.

3. Political Philosophy

In addition to her substantial work on natural philosophy, Cavendish also wrote many other works in a variety of genres, from essays on social issues to poems and plays, even the fantastic utopian fiction The Blazing World. Unlike her work on natural philosophy, however, in which she sets out her views in relatively systematic ways and in philosophical treatises, her thoughts on social or political issues appear in works of fiction or in essays strongly conditioned by rhetorical devices. For example, in Orations of Divers Sorts, she speaks in a variety of voices, imagining several fictional interlocutors who present a number of positions on issues, without indicating the author’s own views. Similarly, in her fiction, she often has several characters advocate for philosophical positions, which complicates any attribution of that view we might make to the author herself. Indeed, in The Blazing World Margaret Cavendish, the Duchess of Newcastle, appears as a character, who advises the Empress of the Blazing World on how her society ought to be governed. In this case, we might feel fairly confident that the views espoused by the character of Cavendish accord with the author’s own, but such attributions should be made only tentatively. Despite the challenges presented by the genres, in which she chose to address these issues, we might still attribute certain general views to her. Among the recurring issues she addressed are aristocracy, gender and fame.

a. Religious Liberty

To see the difficulty in ascribing unambiguous views to Cavendish in these works, consider her thoughts on liberty and stability. In her 1666 fictional work The Blazing World, an Empress restructured her subjects into professional scientific societies. In the story, this change results in a breakdown of social harmony; the old institutions, by which the society had harmoniously functioned, begin to fail, there is strife and faction, and anarchy and civil war loom. Into this situation arrives the character of Margaret Cavendish who advises the formation of a single state sponsored religion. She further instructs the Empress in architectural details, indicating that an imposing cathedral be built from a magical burning stone found in this fictional world. Made, again, by some magical device, to float above the city, with a voice issuing from the Church with booming decrees that the old ways be reinstated, with everyone being born into and retaining the stations. The character of Cavendish proposes that doing so will cow the factious citizens and make them agree, so that cobblers will beget cobblers, soldiers give rise to soldiers and so on. When the Empress executes this plan social harmony is restored. This suggests to the reader that the author Cavendish opposes the sort of political progress that the Empress had proposed; the reader might also conclude that Cavendish supports the institution of a strong state Church.

Yet in her 1662 Orations of Divers Sorts, she states in one of her orations that, if the people have already adopted a variety of religious views, then the government should grant liberty of conscience—that is, freedom of religion—because doing so is the only way to maintain peace. Indeed she says explicitly there that the government should grant this liberty, because a failure to do so will result in anarchy. Then, in the next oration immediately after, she argues from a different perspective, claiming instead that liberty of conscience would lead to liberty in the state, which in turn would result in anarchy. Political liberty, she claims, undermines the rule of law, without which there can be no justice and thus there will be anarchy. Finally, she presents a third oration in defense of a middle view. There she argues that liberty of conscience is acceptable if it concerns only private devotions, but not if it disrupts the public. In other words, if their religious beliefs do neither violate any laws nor harm the public, then those beliefs are to be allowed. We might speculate that she intends this final, middle view to be taken as the author’s own, but it is not always clear, especially when, rather than presenting two views and concluding with a compromise, she instead presents six or seven different opinions, as she does on the question of whether women are equal to men. Even so, the reader may suspect that, in this case, the compromise view is closest to Cavendish’s own.

One feature that unites these varied discussions, however, is Cavendish’s fundamental commitment to the importance of political stability. In each of the above cases, she motivates her position by assuming that social and political stability must be preserved above all. All the orations, as well as the character of Cavendish in The Blazing World, seem to assume that political stability is the goal and that the sovereign ought to employ whatever means will be successful in securing it. Like Hobbes, then, Cavendish takes the primary function of the State to provide stability. This attitude recurs in her defenses of royalism and aristocracy.

b. Royalism and Aristocracy

Cavendish came from a family of royalists, served as a maid in waiting to Queen Henrietta Maria during her and Charles the Second’s exile from England at the hands of the republican revolutionaries of Cromwell and married one of Charles’s staunchest royalist supporters, William Cavendish, Duke of Newcastle. Her commitment to royalism and, more generally, to aristocracy, appears frequently in her writing. When she discusses how a country ought to be governed, she is unwavering in her view that states are best ruled by a King or Queen, who should come from the aristocracy.

One can draw an interesting analogy between her natural philosophy and her politics here. When discussing the distinction between health and illness in animals, Cavendish describes the organism as a body politic; the healthy body is one, in which each part of the body plays its role appropriately, whereas a diseased body is one, in which one or more parts are in rebellion, acting against their natures, to the detriment of the whole organism. Indeed, given her vitalism and panpsychism, she might describe disease in the human body and political unrest or rebellion in remarkably similar terms. In both cases, the whole body is composed of a variety of different parts, each with its own distinctive activity or motion. Each part knows its role, its place, in the body politic, yet each part is free to direct its motions in a way contrary to its natural activity. If a part chooses to do so, it will throw the orderly harmony of the whole out of balance. To expand upon this metaphysical account, we might say that, for Cavendish, people have certain stations—roles and places—in society from birth by nature and social harmony is achieved when the citizens conduct themselves according to their knowledge of their own distinctive activities. As long as the cobblers cobble, the soldiers defend, the judges judge and the rulers rule, social harmony will be maintained and each person can cultivate themselves accordingly.

Indeed, this seems to be one of the central features of Cavendish the character’s advice to the Empress in The Blazing World. Being a fantastical and quasi-science fictional story, The Blazing World features citizens of a variety of animal species, all sentient, capable of human language and so on. Originally, each species has their own distinctive roles, belonging to their own, species-specific guilds. It is to this world that Cavendish urges the Empress to return, one where the citizens are like different species, each with their own peculiar skills and roles received in virtue of what sorts of people their parents were. If the people of The Blazing World simply accepted the stations into which they were born, social harmony would be regained. It is difficult not to see this as a parable of the Restoration of Charles II and the English aristocracy; peace is restored to England by the return of the aristocracy. Moreover, in 1665, the year before The Blazing World was published, her family was restored their lands and her husband was advanced to Dukedom for his service to the King during the Civil Wars.

c. Gender

Cavendish is also described at times as an early feminist. To be sure, her own remarkable life as an author and philosopher leads many to take her as an exemplar; one might say she was a feminist in deed, if not always in word.

Beyond that, though, some scholars argue that her writings are feminist as well. For many of the reasons cited above, such claims can be complicated. Consider the seven orations on women in her Orations of Divers Sorts. There she presents seven speeches that take up a variety of positions. She begins by lamenting the fact that men possess all the power and women entirely lack it. In a subsequent oration, she speculates that women lack power in society, due to natural inferiority. She then counters in the next oration that women might be able to achieve as much as men were they given the opportunity to engage in traditionally masculine activities. But the next speaker claims that, were women to imitate men in this way, they would become “hermaphroditical.” Instead, this orator suggests, women should cultivate feminine virtues such as chastity and humility. In the very next oration, however, the orator suggests that feminine virtues are inferior to masculine, so women should pursue masculine virtues instead. She concludes the series of orations on this topic with a new position, arguing that women are in fact superior to men because women, through their beauty, can control men.

What is the reader to make of this series of orations? It seems likely that Cavendish affirms the following empirical facts about her society: women lack power; women could gain fame and even perhaps power if they pursued masculine virtues; they might even be equally capable as men in cultivating these virtues; yet women would be despised if they did pursue these virtues; if women cultivated feminine virtues, they would not be despised and could even acquire a kind of indirect power, but such a state of affairs is ultimately inferior to the power men possess. What is less clear is whether Cavendish really believes that the pursuit of so-called masculine virtues would somehow harm women by causing them to deny their natures. In other words, it is not clear from these orations whether Cavendish thinks women are naturally inferior to men. In her earlier Worlds Olio, on the other hand, she seems less ambivalent, claiming that women are in general inferior to men at rhetoric. Some women may cultivate skill in rhetoric to rival and even exceed that of men, but they are few, she claims, in this work.

Some readers might point to The Blazing World, and to the power of the Empress or the success of the character of Cavendish as a political adviser. It is true that the Empress leads her people in a successful naval battle, defeating a mortal enemy of her homeland. A similar event occurs in her story Bell in Campo. Even so, the considerations above suggest that social harmony is restored because she returns to aristocratic values. After all, the notion that a woman might lead an empire, even into war, would not be so foreign to an English subject in the 1660s, given that Queen Elizabeth ruled just a few decades before and had overseen the important naval defeat of the Spanish Armada.

From her first work and throughout her career, Cavendish engaged the issue of women in her writing, reflecting on her own experience as a woman and how, or whether, it shaped her writing or philosophy. Thus, with her impressive life and regular consideration of the relevance of gender to her thought, Cavendish can be seen as an important precursor for later more explicitly feminist writers, even if she herself might not be aptly so described.
