In this paper I adduce a new argument in support of the claim that IBE is an autonomous form of inference, based on a familiar, yet surprisingly, under-discussed, problem for Hume’s theory of induction. I then use some insights thereby gleaned to argue for the claim that induction is really IBE, and draw some normative conclusions.

In this paper, I consider some ways in which the Copy Principle and Hume’s nominalism impinge on one another, concluding that the marriage is not a happy one. I argue for the following claims. First, Hume’s argument against indeterminate ideas isn’t cogent even if the Copy Principle is accepted. But this does not vindicate Locke: the imagistic conception of ideas, presupposed by the Copy Principle, will force Locke to accept something like Hume’s view of the way general terms function, the (...) availability of abstract ideas notwithstanding. Second, Hume’s discussion of nominalism provides support for the “old Hume” interpretation, which takes the Copy Principle to be a criterion of meaningfulness, as against the “new Hume” reading, according to which it constrains what we can know. Finally, nominalism forces Hume to adopt a more complicated theory of ideas. (shrink)

The Significance Argument (SA) for the irreducibility of consciousness is based on a series of new puzzle-cases that I call multiple candidate cases. In these cases, there is a multiplicity of physical-functional properties or relations that are candidates to be identified with the sensible qualities and our consciousness of them, where those candidates are not significantly different. I will argue that these cases show that reductive materialists cannot accommodate the various ways in which consciousness is significant and must allow massive (...) vagueness in conscious experience. I also will argue that a nonreductive theory of the conscious-of relation can easily provide a very satisfying, unified explanation of the ways in which this relation is significant. (shrink)

Anselm's Ontological Argument fails, but not for any of the various reasons commonly adduced. In particular, its failure has nothing to do with violating deep Kantian principles by treating ‘exists’ as a predicate or making reference to ‘Meinongian’ entities. Its one fatal flaw, so far from being metaphysically deep, is in fact logically shallow, deriving from a subtle scope ambiguity in Anselm's key phrase. If we avoid this ambiguity, and the indeterminacy of reference to which it gives rise, then his (...) argument is blocked even if his supposed Meinongian extravagances are permitted. Moreover it is blocked in a way which is straightforward and compelling (by contrast with the Kantian objections), and which generalizes easily to other versions of the Ontological Argument. A significant moral follows. Fear of Anselm's argument has been hugely influential in motivating ontological fastidiousness and widespread reluctance to countenance talk of potentially non-existing entities. But if this paper is correct, then the Ontological Argument cannot properly provide any such motivation. Some of the most influential contributions to ontology, from Kant to Russell and beyond, rest on a mistake. (shrink)

I propose a reading of Berkeley's Essay towards a New Theory of Vision in which Molyneux-type questions are interpreted as thought experiments instead of arguments. First, I present the general argumentative strategy in the NTV, and provide grounds for the traditional reading. Second, I consider some roles of thought experiments, and classify Molyneux-type questions in the NTV as constructive conjectural thought experiments. Third, I argue that (i) there is no distinction between Weak and Strong Heterogeneity theses in the NTV; (ii) (...) that Strong Heterogeneity is the basis of Berkeley's theory; and (iii) that Molyneux-type questions act as illustrations of Strong Heterogeneity.

Abstract The grammar of spatial and temporal concepts cannot, it is argued, be the same in their application to the (manifest) world as perceived and to the (nether) world of unobservable causes as modelled in physics. A parallel case is the dual meaning of colour words, for hues and for material dispositions. The keys to differentiating the two main ranges of uses of ?s? and ?t? are: differences in criteria of numerical and qualitative identity in the two ?worlds'; differences in (...) the logic of indexicals in each context; the explanatory role of powers. The differences can be illustrated in a close analysis of the concept of velocity. (shrink)

Thomas Reid's Essays on the Active Powers presents what is probably the most thoroughly developed version of agent-causal libertarianism in the modern canon. While commentators today often acknowledge Reid's contribution, they typically focus on what appears to be a serious problem for the view: Reid appears to commit himself to a position according to which acting freely would require an agent to engage in an infinite number of exertions of active power. In this essay, we maintain that, properly understood, Reid's (...) version of agent-causal libertarianism generates no regress of exertion. Our discussion begins by presenting Reid's account of free action and why it appears vulnerable to a worrisome regress. We then consider three attempts to address the regress in the contemporary literature offered by William Rowe, Gideon Yaffe, and James Van Cleve, which we find unsatisfactory. We then develop a solution to the worry—one that takes very seriously both what Reid means by an ‘efficient’ cause and his appeal to normative features when explaining action. We call it the ‘networked capacity’ view. (shrink)

Going beyond the biological and physiological limitations imposed on us by the human body is something which the human race has strived to do throughout its history. There is something about our human nature that compels us to strive for improvement and enhancement in our physical and mental performance, and to stretch ever further the boundaries of human accomplishment. Nowhere can a stronger desire for enhanced performance be found than in the realm of competitive sport and, it is certainly arguable (...) that, there are very few sports that can rival the competitiveness, endurance and physical exertion involved in the sport of boxing. Transhumanism is borne of this desire for continuous improvement and the refusal to resign ourselves to the restrictions placed on us by our natural biological constitution and environment, enhancing human capabilities and capacities by way of new and emergent technologies. With regard to sport, transhumanism could provide us with the ability to train longer, run, swim or cycle faster, jump higher, throw further and, in the case of boxing, punch harder. However, it is not restricted or confined to the enhancement of our physical powers, but could equally-well serve to improve our psychological capacities and alter the way in which we perceive and experience the world. In this way transhumanism could be employed to change the content of experience. (shrink)

This essay will canvass recent philosophical discussion of accounts of human (free) agency that deploy a notion of agent causation . Historically, many accounts have only hinted at the nature of agent causation by way of contrast with the causality exhibited by impersonal physical systems. Likewise, the numerous criticisms of agent causal theories have tended to be highly general, often amounting to no more that the bare assertion that the idea of agent causation is obscure or mysterious. But in the (...) past decade, detailed accounts of agent causation have been offered (chiefly by Randolph Clarke and Timothy O’Connor), and they have occasioned more specific objections in turn. These recent accounts and objections to them will be my primary focus in what follows. But first I will identify two distinct motivations that have been advanced for adopting an agent causal approach to human agency and the ontological and metaphysical commitments common to any version of this approach.

Defenders of the Knowledge Argument contend that physicalism is false because knowing all the physical truths is not sufficient to know all the truths about the world. In particular, proponents of the Knowledge Argument claim that physicalism is false because the truths about the character of conscious experience are not knowable from the complete set of physical truths. This dissertation is a defense of the Knowledge Argument. Chapter one characterizes what physicalism is and provides support for the claim that if (...) knowing all the physical truths is not sufficient to know all the truths about the world, then physicalism is false. In chapter two, I defend the claim that knowing all the physical truths is not sufficient for knowing all the truths about the world. In addition to mounting a prima facie case for the knowledge intuition, I present and defend an epistemology grounded in direct acquaintance to provide a more substantive argument to accept it. Chapters three through five address the physicalist objections to the Knowledge Argument. The first set of objections advocates that knowing all the physical truths is, in fact, sufficient for knowing all the truths about the world. The next set of objections admits that there is some sense in which knowing all the physical truths is not sufficient for knowing all the truths about the world. However, these objections maintain that the kind of knowledge that is absent from the complete set of physical truths is know-how or knowledge by acquaintance, and not factual or propositional knowledge. The final set of objections maintain that the kind of propositional knowledge that is left out of the complete set of physical truths is compatible with physicalism. My response to these objections is part of advancing my prima facie case for the Knowledge Argument. The final chapter addresses a structural question that pertains to the Knowledge Argument. Some philosophers have maintained that the structure of the Knowledge Argument invites a kind of self-refutation of any systematic account of reality. The concern is that the Knowledge Argument proves too much, and that the dualist who uses the argument to refute physicalism risks the argument defeating his own position. I will argue that the Knowledge Argument does not refute dualism. (shrink)

I Introduction This essay will canvass recent philosophical accounts of human agency that deploy a notion of 'self' (or 'agent') causation. Some of these accounts try to explicate this notion, whereas others only hint at its nature by way of contrast with the causality exhibited by impersonal physical systems. In these latter theories, the authors' main argumentative burden is that the apparent fundamental differences between personal and impersonal causal activity strongly suggest mind-body dualism. I begin by noting two distinct, yet (...) not commonly distinguished, philosophical motivations for pursuing an agent-causal account of human agency. In the course of discussing the accounts that some philosophers have developed in response to these considerations, I reconsider both the linkage of agent causation with mind-body dualism and its sharp cleavage from impersonal (or 'event') causation.
