The pantheon of seventeenth-century European philosophy includes some remarkably heterodox deities, perhaps most famously Spinoza’s deus-sive-natura. As in ethics and natural philosophy, early modern philosophical theology drew inspiration from classical sources outside the mainstream of Christianized Aristotelianism, such as the highly immanentist, naturalistic theology of Greek and Roman Stoicism. While the Stoic background to Spinoza’s pantheist God has been more thoroughly explored, I maintain that Hobbes’s corporeal God is the true modern heir to the Stoic theology. The Stoic and Hobbesian (...) gods are necessitarian, entirely corporeal, and thoroughly intermixed with ordinary bodies, while also supremely intelligent, providential, and good. And both gods serve as the ultimate source of diversity and change in a material world divested of Aristotelian forms and causes. Unfortunately, scholars on both sides of the long debate about the sincerity of Hobbes’s theism have not taken very seriously his late articulation of a corporeal theology. One probable reason for this dismissive attitude is a lack of thorough investigation of the historical precedents for such an unusual godhead available to Hobbes. The first part of this article attempts to establish a close congruence between the Stoic and Hobbesian gods. The second part traces the likely sources for Hobbes’s Stoic theology in his intellectual context. (shrink)

This paper brings new work to bear on the perennial question about Hobbes's atheism to show that as a debate about scepticism it is falsely framed. Hobbes, like fellow members of the Mersenne circle, Descartes and Gassendi, was no sceptic, but rather concerned to rescue physics and metaphysics from radical scepticism by exploring corporealism. In his early letter of November 1640, Hobbes had issued a provocative challenge to Descartes to abandon metaphysical dualism and subscribe to a ?corporeal God?; a provocation (...) to which the Frenchman angrily responded, but was perhaps importantly influenced. Hobbes's minimal realism was consonant with atheism, to which Descartes felt he was being forced. Moreover, Hobbes was unrelenting in his battle against Cartesian dualism, for which he saw Robert Boyle's experimental science as a surrogate. (shrink)

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.

The notion of signification is an important part of Hobbes's philosophy of language. It also has broader relevance, as Hobbes argues that key terms used by his opponents are insignificant. However Hobbes's talk about names' signification is puzzling, as he appears to have advocated conflicting views. This paper argues that Hobbes endorsed two different views of names' signification in two different contexts. When stating his theoretical views about signification, Hobbes claimed that names signify ideas. Elsewhere he talked as if words (...) signified the things they named. Seeing this does not just resolve a puzzle about Hobbes's statements about signification. It also helps us to understand how Hobbes's arguments about insignificant speech work. With one important exception, they depend on the view that names signify things, not on Hobbes's stated theory that words signify ideas. The paper concludes by discussing whether arguments about insignificant speech can provide independent support for Hobbes's views about other issues, such as materialism. (shrink)

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.

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.

The status of the laws of nature in Hobbes’s Leviathan has been a continual point of disagreement among scholars. Many agree that since Hobbes claims that civil philosophy is a science, the answer lies in an understanding of the nature of Hobbesian science more generally. In this paper, I argue that Hobbes’s view of the construction of geometrical figures sheds light upon the status of the laws of nature. In short, I claim that the laws play the same role as (...) the component parts – what Hobbes calls the “cause” – of geometrical figures. To make this argument, I show that in both geometry and civil philosophy, Hobbes proceeds by a method of synthetic demonstration as follows: 1) offering a thought experiment by privation; 2) providing definitions by explication of “simple conceptions” within the thought experiment; and 3) formulating generative definitions by making use of those definitions by explication. In just the same way that Hobbes says that the geometer should “put together” the parts of a square to learn its cause, I argue that the laws of nature are the cause of peace. (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.

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.

_ Source: _Volume 29, Issue 1, pp 66 - 85 This paper will deal with the notion of _conatus_ and the role it plays in Hobbes’s program for natural philosophy. As defined by Hobbes, the _conatus_ of a body is essentially its instantaneous motion, and he sees this as the means to account for a variety of phenomena in both natural philosophy and mathematics. Although I foucs principally on Hobbesian physics, I will also consider the extent to which Hobbes’s account (...) of _conatus_ does important explanatory work in his theory of human perception, psychology, and political philosophy. I argue that, in the end, there are important limitations in Hobbes’s account of _conatus_, but that Leibniz adapted the concept in important ways in developing his science of dynamics. (shrink)

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.

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)
