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)

Margaret Cavendish is widely known as a materialist. However, since Cavendishian matter is always in motion, “matter” and “motion” are equally important foundational concepts for her natural philosophy. In Philosophical Letters (1664), she takes to task her materialist rival Thomas Hobbes by assaulting his account of accidents in general and his concept of “rest” in particular. In this article, I argue that Cavendish defends her continuous-motion view in two ways: first, she claims that her account avoids seeing accidents as capable (...) of generation and annihilation, which she argues is inconceivable; and second, she contends that according to Hobbes’s own view “rest” is an absurd conception since it cannot be drawn from experience. Beyond its function as a defense, I claim that Cavendish’s focused criticism of “rest” shows that she is a perceptive reader of Hobbes’s natural philosophy, insofar as her criticisms undercut the two a priori principles of Hobbesian physics. Finally, I show how her views developed in more detail in Philosophical and Physical Opinions (1663) and Observations upon Experimental Philosophy ([1666] 2001) avoid the worries she raises for Hobbesian materialism.

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)

My Cavellian argument is that the form or space of skeptical questioning -- regardless of whether we are asking about the veridicality of the appearance of another's pain, about the veridicality of the meaning of a word or phrase, about the veridicality of a perception, etc. -- leaves behind the ordinary, finite, and social activities and practices which make meaningful language use possible. But Cavell does not mean "left behind" in the sense that returning to these finite and social practices (...) of language use will defeat skepticism; Cavell thinks that the direct attempt to defeat skepticism has still not adequately understood what the appearance of a skeptical problem has deflected. Rather, in Cavell's philosophy, if we return to the everyday use of language after working through the threat of skepticism and after coming to terms with what led us into skeptical thinking, what we find is a renewed relation to the felt life of the ordinary mind, one which acknowledges those unhandsome elements of our condition which skepticism would seek to deny. In later work, Cavell will describe the proper response to skepticism as a transformation of the actual everyday into the eventual everyday. With respect to the question of how language corresponds to or represents the world, I suggest, throughout this dissertation, that this question is a confused response to the fact of our inheritance of language and culture, the fact that we are born into a social, already-made system of meanings over which in many ways we have astonishingly little freedom. And that conclusion, I argue -- the conclusion that a particular form of skepticism deflects -- is yet another starting point for Cavell's philosophy, an insight brought out only through an engagement with skepticism.
