I discuss what Aquinas’ doctrine of divine simplicity is, and what he takes to be its implications. I also discuss the extent to which Aquinas succeeds in motivating and defending those implications.

Saul Kripke, in a series of classic writings of the 1960s and 1970s, changed the face of metaphysics and philosophy of language. Christopher Hughes offers a careful exposition and critical analysis of Kripke's central ideas about names, necessity, and identity. He clears up some common misunderstandings of Kripke's views on rigid designation, causality and reference, and the necessary a posteriori and contingent a priori. Through his engagement with Kripke's ideas Hughes makes a significant contribution to ongoing debates on, inter alia, (...) the semantics of natural kind terms, the nature of natural kinds, the essentiality of origin and constitution, the relative merits of 'identitarian' and counterpart-theoretic accounts of modality, and the identity or otherwise of mental types and tokens with physical types and tokens. No specialist knowledge in either the philosophy of language or metaphysics is presupposed; Hughes's book will be valuable for anyone working on the ideas which Kripke made famous in the philosophy world.

Locke thought that it was impossible for there to be two things of the same kind in the same place at the same time. I offer (what looks to me like) a counterexample to that principle, involving two ships in the same place at the same time. I then consider two ways of explaining away, and one way of denying, the apparent counterexample of Locke's principle, and I argue that none is successful. I conclude that, although the case under discussion (...) does not refute Locke's principle, it constitutes a serious challenge to it. (shrink)

Proprioception is a crucial sensory modality involved in the control and regulation of coordinated movements and in motor learning. However, the extent to which proprioceptive acuity is influenced by local muscle fatigue is obscured by methodological differences in proprioceptive and fatiguing protocols. In this study, we used high resolution kinematic measurements provided by a robotic device, as well as both frequency and time domain analysis of signals captured via surface electromyography (sEMG) to examine the effects of local muscle fatigue on (...) wrist proprioceptive acuity in 16 physically and neurologically healthy young adults. To this end, participants performed a flexion/extension ipsilateral joint position matching test (JPM), after which a high-resistive robotic task was used to induce muscle fatigue of the flexor carpi radialis (FCR) muscle. The JPM test was then repeated in order to analyze potential changes in proprioceptive acuity. Results indicated that the fatigue protocol had a significant effect on movements performed in flexion direction, with participants exhibiting a tendency to undershoot the target before the fatigue protocol (-1.218°), but overshooting after the fatigue protocol (0.587°). In contrast, in the extension direction error bias values were similar before and after the fatigue protocol as expected (pre = -1.852°, post = -1.237°) and reflected a tendency to undershoot the target. Moreover, statistical analysis indicated that movement variability was not influenced by the fatigue protocol or movement direction. In sum, results of the present study demonstrate that an individual’s estimation of wrist joint displacement (i.e., error bias), but not precision (i.e., variability), is affected by muscular fatigue in a sample of neurologically and physically healthy adults.

Individual differences in children's talk about inner states are striking, but how should they be interpreted? This study used transcripts of preschoolers’ conversations with siblings and best friends to address this question in two ways. Our first aim was to elucidate the exact nature of individual differences by contrasting categories (emotion/desire vs. cognitive state) and referents (own vs. other/shared) of inner state talk. Our second aim was to compare performance vs. competence views of inner state talk by exploring (i) the (...) stability of individual differences in inner state talk across different relationships and (ii) the cognitive correlates of inner state talk. A sample of 44 children (mean age = 4 years 3 months) was observed for 20 minutes at home playing with a sib and for 20 minutes at school playing with a best friend. Videos were transcribed and coded for the frequency and form of inner state talk (e.g., talk about different categories of inner state, or about own vs. others’ inner states). During the school visits, children completed a set of tasks tapping theory-of-mind skills and verbal ability. Individual differences in inner state talk (especially reference to others’ inner states) were stable across relationships. There was no association between individual differences in talk about cognitive vs. emotion/desire states, although both categories of inner state talk were significantly associated with individual differences in children's theory-of-mind skills.

Sider has argued that four‐dimensionalism can be given a clear and coherent formulation, and has attempted to provide one. He has also argued that three‐dimensionalism resists adequate formulation. I argue that Sider's worries about whether there is an adequate formulation of three‐dimensionalism are misplaced, and suggest a formulation of three‐dimensionalism different from the ones considered and rejected by Sider. I then give a ‘matching’ formulation of four‐dimensionalism, and argue that it captures four‐dimensionalism better than Sider's own formulation of that doctrine.

I express some reservations about Hart and Hill's attempt to show that certain Scriptural passages show that God sometimes intends that sins occur, though I express sympathy for the view that God sometimes intends that sins occur.

The learning society has been advocated as an answer to current economic, political and social problems by a wide coalition of interests, including politicians, employers and educators. Here we critically analyse the concept as a myth; that is, as an idea which may or may not have validity, but which many people believe in. For the purpose of this analysis, the learning society is set alongside four other myths upon which it builds: those of productivity, change, lifelong education and the (...) learning organisation. It is argued that the United Kingdom cannot currently be considered to be a learning society, nor is it likely to become one in the foreseeable future. But the idea of the learning society retains an important role as a myth, in drawing together and channelling energies in directions sought by policy-makers. (shrink)

According to egalitarians, there is no privileged now-possible history. Egalitarianism seems to provide an attractive way to reconcile openness and omniscience, but, I argue, it does not.

This collection of papers by prominent feminist thinkers advances the positive feminist project of remapping the moral by developing theory that acknowledges the diversity of women.

In this paper we investigate some families of decision problems associated with a restricted class of Post canonical forms, specifically, those defined over one-letter alphabets whose productions have single premises and contain only one variable. For brevity sake, we call any such form an RPCF (Restricted Post Canonical Form). Constructive proofs are given which show, for any prescribed nonrecursive r.e. many-one degree of unsolvability D, the existence of an RPCF whose word problem is of degree D and an RPCF with (...) axiom whose decision problem is also of degree D. Finally, we show that both of these results are best possible in that they do not hold for one-one degrees. (shrink)

A constructive proof is given which shows that every nonrecursive r.e. many-one degree is represented by the family of decision problems for partial implicational propositional calculi whose well-formed formulas contain at most two distinct variable symbols.

This paper explores the relationship between Fukuyama’s account of history and Derrida’s theory of hauntology. Initially, I use Derrida’s idea of hauntology tocritique Fukuyama’s account of an end of history. I argue that Derrida’s idea of a hauntology is a valuable theoretical tool for theorising about politics, sinceDerrida shows that the death of a particular social/political system (e.g. Communism) does not entail the death/devaluing of the thinker(s) who inspired that system, since critics of the contemporary social and political order may (...) have something valuable to offer contemporary political thought. However, I do notendorse the view that history cannot reach an end point just because there are specters waiting to return. Instead, I argue that it is possible to bridge theapparent dualistic binary between Derrida’s hauntology and Fukuyama’s end of history, since the specter is something which must be recognised and realised atthe end of history.

Thomas Aquinas was the most influential philosopher of the Middle Ages, and one of the most famous Christian theologians of all time. His philosophy is a powerful synthesis of Aristotle and Plato presented within a Christian framework. His "five ways" to prove the existence of God are studied by undergraduates on many theology and philosophy of religion courses. Apart from his specifically theological works, he spent much of his time writing about metaphysics, all of which was to have important ramifications (...) for epistemology, philosophy of mind and ethics. Christophe Hughes focuses mostly on the philosophical Aquinas; beginning with a chapter on his life and works he goes on to discuss Aquinas's metaphysics and his theory of human beings in general, covering his ideas about body and soul, the mind, and free will.

I argue that the Proslogion 2 argument rests on Meinongian assumptions, and Meinongianism is more defensible than many metaphysicians think, but although Meinongianism can be defended from objections, the most promising strategies for doing that call into question the cogency of the Proslogion 2 argument, so that argument is less than convincing, even if Meinongianism is true.

Thomas Aquinas is one of the most important figures in the history of philosophy and philosophical theology. Relying on a deep understanding of Aristotle, Aquinas developed a metaphysical framework that is comprehensive, detailed, and flexible. Within that framework, he formulated a range of strikingly original and carefully explicated views in areas including natural theology, philosophy of mind, philosophical psychology, and ethics. In this book_, _Christopher Hughes focuses on Aquinas’s thought from an analytic philosophical perspective. After an overview of Aquinas’s life (...) and works, Hughes discusses Aquinas’s metaphysics, including his conception of substance, matter, and form, and his account of essence and existence; and his theory of the nature of human beings, including his critique of a substance dualism that Aquinas attributes to Plato, but is usually associated with Descartes. In the final chapters, Hughes discusses Aquinas’s account of the existence and nature of God, and his treatment of the problem of evil, as well as his ideas about the relation of goodness to being, choice, and happiness. Aquinas on Being, Goodness, and God is essential reading for students and scholars of Aquinas, and anyone interested in philosophy of religion or the history of medieval philosophy. (shrink)
