Pure Wit: The Revolutionary Life of Margaret Cavendish by Francesca Peacock, Apollo 14 Sept. 2023, 384 pages

“Fame is nothing but a great noise… therefore I wish my book may set a-work every tongue.”

Margaret Cavendish

“For I doubt not, but if it had been a thing contrary to any man's right of dominion, or to the interest of men that have dominion, that the three angles of a triangle should be equal to two angles of a square, that doctrine should have been, if not disputed, yet by the burning of all books of geometry suppressed, as far as he whom it concerned was able.”

Thomas Hobbes

“Thus, Karl Marx wrote about the British origin of modern materialism. If Englishmen nowadays do not exactly relish the compliment he paid their ancestors, more's the pity. It is none the less undeniable that Bacon, Hobbes, and Locke are the fathers of that brilliant school of French materialism which made the eighteenth century, despite all battles on land and sea won over Frenchmen by Germans and Englishmen, a pre-eminently French century, even before that crowning French Revolution, the results of which we outsiders, in England as well as Germany, are still trying to acclimatize.”

Frederick Engels- Dialectics of Nature

The first thing that emerges from Francesca Peacock's 2023 book is that Margaret Cavendish (1623–1673), Duchess of Newcastle, a staunch Royalist author and philosopher, was profoundly influenced by the English bourgeois revolution. Although hostile to the revolution and all it stood for, she utilised her unique intellectual voice to understand what was unfolding around her as the world turned upside down.

The English Civil War and Revolution of the 1640s was not, as Whig historians preferred to imagine, a constitutional misunderstanding between king and Parliament. According to historian Christopher Hill, it was a genuine class revolution: the rising bourgeoisie, allied with sections of the gentry, overthrew the feudal monarchical order and cleared the ground for the development of capitalism in England. Hill, the greatest historian of this period, demonstrated that the execution of Charles I was not a ghastly mistake but "a complete break with the feudal past," of profound revolutionary significance. When the people put their king on trial and beheaded him, no subsequent monarch ever sat entirely comfortably on that throne again.

Although she lived over a century before Karl Marx, some left-leaning modern academics and writers who analyse her work through a semi-Marxist lens have even argued that there are strong parallels between her 17th-century natural philosophy and later theories of dialectical materialism. Specifically, her belief in a self-moving, intelligent, and interconnected material world renders her a "precursor" to Marxist dialectical materialism.

This has made Cavendish a genuinely fascinating figure of the 17th-century English bourgeois revolution. A prolific writer across genres (philosophy, poetry, drama, fiction, and early proto-science fiction with The Blazing World), she engaged seriously with the mechanist natural philosophy of her era, debating figures like Descartes, Hobbes, and van Helmont. She was one of the first women admitted to a meeting of the Royal Society. Her intellectual ambitions were remarkable for any person of her time.

The connection between Margaret Cavendish and Thomas Hobbes is well worth a look at. Both were central figures in 17th-century English intellectual life, and their relationship illuminates some of the deepest questions in the history of materialism.

Hobbes (1588–1679) was not, as some liberal and postmodern academics would have it, a reactionary ideologue of authoritarianism. He was, as Engels recognised, one of the founders of modern materialism, a thinker who, alongside Bacon and Locke, formed the philosophical chain that ran from England through the French Enlightenment, ultimately contributing to the intellectual conditions that made the French Revolution possible and, beyond it, to dialectical and historical materialism itself.

Hobbes’s connection with Cavendish was both direct and personal. Margaret Cavendish was the wife of William Cavendish, Duke of Newcastle, the very Cavendish family whose patronage sustained Hobbes for over seven decades. Margaret Cavendish lived at the centre of this intellectual world. During the Civil War and the Interregnum, the Cavendish household, in exile on the Continent, was a gathering point for Royalist émigrés and natural philosophers, and Hobbes was part of this milieu.

Her philosophical position puts her in an interesting relationship to Hobbes. Both were materialists but of significantly different kinds. Cavendish rejected the mechanistic materialism that Hobbes (and Descartes, whom she also engaged with critically) championed. Against the view that matter is inert and moved only by external mechanical force, Cavendish argued for a vitalist materialism: matter itself, she held, is active, self-moving, and possessed of something like perception or cognition at every level. She was also an outspoken critic of the experimental method championed by the Royal Society, arguing (in her Observations upon Experimental Philosophy, 1666) that telescopes and microscopes distort rather than reveal nature. That reason applied to natural observation without a mechanical apparatus is more reliable.

This is where the contradictions of her class position become interesting. She was an aristocratic Royalist — her husband, William Cavendish, was a leading commander for Charles I, and the family spent years in exile during the Interregnum. Her intellectual freedom was inseparable from her class privilege. Her access to books, philosophical correspondence, and scientific circles was a product of her position at the apex of the aristocratic hierarchy, not a challenge to it. She was not, in any meaningful sense, a "revolutionary"; she was a defender of the old feudal-aristocratic order against the revolutionary bourgeoisie that was remaking England.

The bourgeois revolution she opposed was, at the same time, creating social ferment that was generating the Scientific Revolution, dismantling Aristotelian scholasticism, fostering a new interest in nature as a material reality governed by discoverable laws, and challenging religious authority. The very intellectual tools she used were being forged by the same historical process that had destroyed her family's wealth and power. She could not entirely escape the spirit of her age, even as she tried to reconstruct the aristocratic world that had been shattered.

As the Marxist writer David North so eloquently put it, “Until the early seventeenth century, even educated people still generally accepted that the ultimate answers to all the mysteries of the universe and the problems of life were to be found in the Old Testament. But its unchallengeable authority had been slowly eroding, especially since the publication of Copernicus’s De Revolutionibus in the year of his death in 1543, which dealt the death blow to the Ptolemaic conception of the universe and provided the essential point of departure for the future conquests of Tycho Brahe (1546-1601), Johann Kepler (1571-1630) and, of course, Galileo Galilei (1564-1642). Intellectually, if not yet socially, the liberation of man from the fetters of Medieval superstition and the political structures that rested upon it was well underway. The discoveries in astronomy profoundly changed the general intellectual environment. Above all, there was a new sense of the power of thought and what it could achieve if allowed to operate without the artificial restraints of untested and unverifiable dogmas.

Religion began to encounter the type of disrespect it deserved, and the gradual decline of its authority introduced a new optimism. All human misery, the Bible had taught for centuries, was the inescapable product of the Fall of Man. But the invigorating scepticism encouraged by science in the absolute validity of the Book of Genesis led thinking people to wonder whether man couldn't change the conditions of his existence and enjoy a better world.”[1]

Peacock’s first book, Pure Wit: The Revolutionary Life of Margaret Cavendish, makes a valuable contribution by rescuing Cavendish from the obscurity imposed by earlier critics who had laid a considerable number of dead dogs on top of her reputation. However, it exemplifies a trend often found in modern cultural biography: the application of contemporary identity-political categories to historical figures. In this case, Cavendish is portrayed through the lens of modern preoccupations, with her eccentricity, gender nonconformity, prolific publication, and resistance to social expectations for women recast as attributes of a proto-feminist "revolutionary".

This approach reflects more the concerns of today's upper-middle-class academic culture than the realities of 17th-century England. While reading Peacock’s work critically can yield valuable insights into Cavendish's intellectual life, the reader needs to maintain a degree of scepticism regarding the "revolutionary" framing. Such a perspective tends to absorb a complex historical figure into present-day identity-political narratives, thereby oversimplifying the intricate class dynamics that characterised the English Revolution.

Cavendish is now celebrated as an early feminist icon. She was the first woman to participate in a Royal Society meeting, boldly published her work despite norms that expected women to stay hidden, and earned the nickname "Mad Madge" for her unconventional behaviour. This recuperation is not entirely wrong, but it is ideologically loaded in a specific way: it abstracts Cavendish's gender from her class. It presents her eccentricity as a kind of individual heroism.

She stands in this constellation as a paradox: a serious philosophical mind whose very creativity was unlocked by the same revolution she personally mourned. That paradox is not a biographical curiosity; it is a demonstration of the materialist conception of history itself: that the development of human thought is inseparable from the class conflicts that drive history forward.
