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)

The subject of this chapter is the complex and confusing course of the discussion of cause and teleology before and during the period of Mill and Comte, and its aftermath up to the early years of the twentieth century in the thinking of several of the major founding figures of disciplinary social science. The discussion focused on the problem of the sufficiency of causal explanations, and particularly the question of whether some particular fact could be explained without appeal to purpose. (...) In response to such questions, the defenders of the new conception attempted to replace older terminology with new (“function” for “purpose,” for example), sometimes muddling the issues, sometimes turning them into terminological disputes, and sometimes making the different positions difficult to distinguish. The problem of methodological unity in the social sciences is rooted in the discussions of the time. (shrink)

Thomas Hobbes was, rather famously, a nominalist. The core of that nominalism is the belief that the only universal things are universal names: there are no universal objects, or universal ideas. This paper looks at what Hobbes's views about universal names were, how they evolved over time, and how Hobbes argued for them. The remainder of the paper considers two objections to Hobbes's view: a criticism made by several of Hobbes's contemporaries, that Hobbes's view could not account for people saying (...) the same thing in different languages; and a more recently popular criticism of Hobbes, that his nominalism's reliance on similarity implicitly (and inconsistently) involves reliance on a universal.

Language was central to Hobbes's understanding of human beings and their mental abilities, and criticism of other philosophers' uses of language became a favorite critical tool for him. This paper connects Hobbes's theories about language to his criticisms of others' language, examining Hobbes's theories of propositions and truth, and how they relate to his claims that various sorts of proposition are absurd. It considers whether Hobbes in fact means anything more by 'absurd' than 'false'. And it pays particular attention to (...) Hobbes's categorization of causes of absurdity and of types of incoherent proposition, arguing that Hobbes's approach is only loosely related to later discussions of category mistakes. (shrink)

Autonomy is, among other things, an actual psychological condition, a capacity that can be developed, and an educational ideal. This paper contextualises, analyses, criticises and extends the theory of Richard S. Peters on these three aspects of autonomy.

Hobbes repeatedly expressed concerns about moral and political language, e.g., about the bad consequences of various uses and misuses of language. He did not simply focus on the consequences though. He also attempted to understand the problems, using the central semantic notion in his philosophy of language, signification. Hobbes, in both the Elements of Law and Leviathan, argues that a wide variety of terms – including ‘good’, ‘bad’, and the names of virtues and vices – have a double and inconstant (...) signification. This paper explores and explains that theory of Hobbes's. (In the course of the discussion, two other interpretations of Hobbes's claims are discussed: Pettit’s discussion in terms of indexicals, and Alexandra’s in terms of sense and reference.) This phenomenon is, Hobbes thinks, pervasive in our use of moral and political language. Indeed he says his analysis applies to all “names of such things as affect us, that is, which please, and displease us” (Leviathan 4.24), which seems a very broad category indeed. This inconstancy of signification has considerable potential to cause confusion and conflict. Given those practical consequences, it is of some importance for Hobbes to find a solution to this problem. The paper examines several possible Hobbesian solutions to the problem. There is, however, reason to think that these suggested solutions cannot completely solve the problem. The paper concludes, then, by arguing that double and inconstant signification would always be a danger, even in a properly constituted Hobbesian commonwealth. (shrink)

In this work we will try to demonstrate the presence and the role that God has in Thomas Hobbes's political philosophy. We consider that this religious belief, that it is the system's equilibrium, guaranties that the Hobbesian political project does not fall into revolutionary or totalitarian excesses. Thus, we shall analyse the arguments of the existence of God that are introduced by the philosopher Malmesbury with the objective of proving that reason does not necessarily lead to atheism, but that such (...) faculty requires the Revelation intervention to be able to channel it into a peaceful and lasting life.

Hobbes’s interpreters have struggled to find a plausible semantics for evaluative language in his writings. I argue that this search is misguided. Hobbes offers neither an account of the reference of evaluative terms nor a theory of the truth-conditions for evaluative statements. Rather, he sees evaluative language simply as having the non-representational function of prescribing actions and practical attitudes, its superficially representational appearance notwithstanding. I marshal the evidence for this prescriptivist reading of Hobbes on evaluative language and show how it (...) sidesteps various textual and philosophical problems that bedevil the traditional interpretations.

Against the dominant view in contemporary Hobbes scholarship, I argue that Hobbes’ philosophy of language implicitly denies that linguistic expressions refer to anything. I defend this thesis both textually, in light of what Hobbes actually said, and contextually, in light of Hobbes’ desertion of the vocabulary of suppositio, which was prevalent in semantics leading up to Hobbes. Hobbes explained away the apparent fact of linguistic reference via a reductive analysis: the relation between words and things wholly reduces to a composite (...) of the relation of signification between words and conceptions on the one hand, and the relation of representation between conceptions and things on the other. Intentionality, for Hobbes, accrues to conceptions, not words. (shrink)

I propose to examine here, at the outset, what I call the asymmetry in Thomas Hobbes's thought between his treatment of civil war and war between states, that is to say, between the departure from the state of nature - when that is a condition prevailing between individuals - and the permanency in the state of nature when it forms a condition existing between states. Secondly, I will address the Kantian progression beyond this asymmetry through the dual introduction of the (...) idea of progress and of ‘cosmo-political’ peace. The attention given in recent years by Habermas to the Kantian idea of perpetual peace [Habermas, 1996], the recent events in Kosovo and Chechnya, and their implications for the shape of an international penal tribunal to judge crimes against humanity, invigorate the questions of civil peace and of rights which transcend state frontiers.
