The machine-organism analogy has played a pivotal role in the history of Western philosophy and science. Notwithstanding its apparent simplicity, it hides complex epistemological issues about the status of both organism and machine and the nature of their interaction. What is the real object of this analogy: organisms as a whole, their parts or, rather, bodily functions? How can the machine serve as a model for interpreting biological phenomena, cognitive processes, or more broadly the social and cultural transformations of the (...) relations between individuals, and between individuals and the environments in which they live? Wired Bodies. New Perspectives on the Machine-Organism Analogy provides the reader with some of the latest perspectives on this vast debate, addressing three major topics:1) the development of a ‘mechanistic’ framework in medicine and biology; 2) the methodological issues underlying the use of ‘simulation’ in cognitive science; 3) the interaction between humans and machines according to 20th-century epistemology.

This essay offers an interpretation of Descartes’ treatment of the concepts of place and space in the Principles of Philosophy. On the basis of that interpretation, I argue that his understanding and application of the concept of space supports a pluralist interpretation of Descartes on extended substance. I survey the Scholastic evolution of issues in the Aristotelian theory of place and clarify elements of Descartes’ appropriation and transformation thereof: the relationship between internal and external place, the precise content of the (...) claim that space and body are really identical, and the way we conceptually distinguish space from body. Descartes applies his concept of space in ways that illuminate the metaphysical structure of extension. In particular, he uses the concept to specify the degree to which finite parts of matter are independent of each other. I argue that for Descartes, conceiving extension as indivisible is an artifact of conceiving it as a space. That is, pace the monistic reading of Cartesian extended substance, regarding extension as indivisible is an artifact of conceiving it in a way more removed from its real nature. (shrink)

ABSTRACTIn this paper, I explore Margaret Cavendish’s engagement with mid-seventeenth-century debates on spirits and spiritual activity in the world, especially the problems of incorporeal substance and magnetism. I argue that between 1664 and 1668, Cavendish developed an increasingly robust form of materialism in response to the deficiencies which she identified in alternative philosophical systems – principally mechanical philosophy and vitalism. This was an intriguing direction of travel, given the intensification in attacks on the supposedly atheistic materialism of Hobbes. While some (...) scholars claim that Cavendish’s views were not formed out of extensive engagement with contemporary thinkers, I suggest that, on the contrary, Cavendish engaged very closely with the views of More, Hobbes and others – including the vitalist thinker Johannes Baptista van Helmont and the mechanical philosopher Henry Power – on the subject of spirits and...

Accounts of Hobbes’s ‘system’ of sciences oscillate between two extremes. On one extreme, the system is portrayed as wholly axiomtic-deductive, with statecraft being deduced in an unbroken chain from the principles of logic and first philosophy. On the other, it is portrayed as rife with conceptual cracks and fissures, with Hobbes’s statements about its deductive structure amounting to mere window-dressing. This paper argues that a middle way is found by conceiving of Hobbes’s _Elements of Philosophy_ on the model of a (...) mixed-mathematical science, not the model provided by Euclid’s _Elements of Geometry_. I suggest that Hobbes is a test case for understanding early-modern system-construction more generally, as inspired by the structure of the applied mathematical sciences. This approach has the additional virtue of bolstering, in a novel way, the thesis that the transformation of philosophy in the long seventeenth century was heavily indebted to mathematics, a thesis that has increasingly come under attack in recent years.

I offer an alternative account of the relationship of Hobbesian geometry to natural philosophy by arguing that mixed mathematics provided Hobbes with a model for thinking about it. In mixed mathematics, one may borrow causal principles from one science and use them in another science without there being a deductive relationship between those two sciences. Natural philosophy for Hobbes is mixed because an explanation may combine observations from experience (the ‘that’) with causal principles from geometry (the ‘why’). My argument shows (...) that Hobbesian natural philosophy relies upon suppositions that bodies plausibly behave according to these borrowed causal principles from geometry, acknowledging that bodies in the world may not actually behave this way. First, I consider Hobbes's relation to Aristotelian mixed mathematics and to Isaac Barrow's broadening of mixed mathematics in Mathematical Lectures (1683). I show that for Hobbes maker's knowledge from geometry provides the ‘why’ in mixed-mathematical explanations. Next, I examine two explanations from De corpore Part IV: (1) the explanation of sense in De corpore 25.1-2; and (2) the explanation of the swelling of parts of the body when they become warm in De corpore 27.3. In both explanations, I show Hobbes borrowing and citing geometrical principles and mixing these principles with appeals to experience. (shrink)

Historians of philosophy are increasingly likely to emphasize the extent to which their work offers a pay‐off for philosophers of un‐historical or anti‐historical inclinations; but this defence is less familiar, and often seems less than self‐evident, to intellectual historians. This article examines this tendency, arguing that such arguments for the instrumental value of historical scholarship in philosophy are often more problematic than they at first appear. Using the relatively familiar case study of René Descartes' reading of his scholastic and Aristotelian (...) contemporaries, the article attempts to problematize this notion of pay‐off from an historian's perspective.

ABSTRACT For Victoria Kahn, Hobbes' argument that fear of violent death is “the passion to be reckoned upon” in explaining what inclines men to peace must be interpreted as a mimetic argument. However, Kahn then notes a paradox that makes Hobbes' thinking problematic: whereas love and the desires are appetites that produce an imitative effect, fear is different. Though also a passion, fear lacks that capacity to produce a mimetic effect or, therefore, to generate a contract. My hypothesis is that (...) resolving the dilemma presented in Kahn's interpretation of Hobbes requires a shift in attention from mimesis to rhetoric and, more specifically, to biological rhetoric as defined by Nancy Struever. This approach to Hobbes makes it possible to understand the rhetorical role of fear in generating and maintaining the social contract, and how the problem that Kahn signals—the impotence of fear in relation to mimesis—can be resolved.

This paper explores Thomas Hobbes’s account of animal life and mind. After a critical examination of Hobbes’s mechanistic explanation of operations of the mind such as perception and memory, I argue that his theory derives its strength from his idea of the dynamic interaction of the body with its surroundings. This dynamic interaction allows Hobbes to maintain that the purposive disposition of the animal is not merely an upshot of its material configuration, but an expression of its distinctive bodily history. (...) In support of Hobbes, I show how this is complemented by his account of the unity and continuity of the animal body in terms of a unification through the self-preserving drive that originates in perception. Nonetheless, I argue that Hobbes’s philosophy of animal life and mental faculties is hindered by a kind of epiphenomenalist perspective that is embedded in his materialist framework, and this perspective leaves the status of ideas and mental content unclear. I explain why Hobbes’s dynamic theory, founded upon the reciprocal determination of moving bodies, supports his idea of animal development and habituation while failing to account for the reflexivity of the mind.

In Metaphysical Themes, Robert Pasnau interprets Thomas Hobbes as an anti-realist about all accidents in general. In opposition to Pasnau, we argue that Hobbes is a realist about some accidents (e.g., motion and magnitude). Section One presents Pasnau’s position on Hobbes; namely, that Hobbes is an unqualified anti-realist of the eliminativist sort. Section Two offers reasons to reject Pasnau’s interpretation. Hobbes explains that magnitude is mind-independent, and he offers an account of perception in terms of motion (understood as a mind-independent (...) feature of body). Therefore, it seems incorrect to call Hobbes an anti-realist about all accidents. Section Three considers Pasnau’s hypothetical response: he might claim that for Hobbes, motion reduces to body and does not exist in its own right. Section Four notes that reductionism about all accidents does not entail anti-realism about all accidents. Even granting Pasnau’s anticipated response, his anti-realist reading does not follow. Contra Pasnau, Hobbes is best understood as claiming that motion and magnitude exist mind-independently. (shrink)

The recent publication of the stenographer's transcript of Whitehead's guest lecture on “social ethics” has shed new light on the relation between his metaphysics and ethics. Instead of including ethics in his philosophy, Whitehead treats it as a distinct, specialized science that does not share in the universality of metaphysics. The present article argues that an analysis of his lecture shows that a nonindividualist Whiteheadian ethics is possible without rupturing the coherence of Whitehead's system or contradicting the ontological or subjectivist (...) principle. As part of a larger transition in Whitehead's thinking during the years 1925–1927, he reformulates the notion of the environment as inheritance and is therefore able to pose the question of the endurance of values at the level of society, which is the purview of ethics. Reconstructing the metaphysical background may provide a “stimulus to the imagination” for ethical debates today, especially in the field of environmental ethics. (shrink)
