‘Naturalized’ philosophers of mind regularly appeal to the empirical psychological literature in support of the ‘theory-theory’ account of the natural epistemology of mental state ascription (to self and others). It is argued that such appeals are not philosophically neutral, but in fact presuppose the theory-theory account of mental state ascription. It is suggested that a possible explanation of the popularity of the theory-theory account is that it is generally assumed that alternative accounts in terms of introspection (and simulation) presuppose a (...) discredited ‘inner ostensive definition’ account of the meaning of mental state terms. However, the inner ostensive definition account is not the only alternative to the theory-theory account of the meaning of mental state terms, and commitment to a theory-theory account of the meaning of mental state terms does not mandate commitment to a theory-theory account of the epistemology of mental state ascription.

The paper advances the hypothesis that George Berkeley's philosophy does not overcome solipsism. In order to do this, it presents four difficulties on his arguments for other existences: (I) the argument about the existence of an external cause for sensitive ideas faces the difficulty of not eliminating the possibility that the mind itself is the cause of these ideas; (II) the argument present in the Dialogues to prove the existence of God is circular: it presupposes the existence of objects distinct (...) from the mind, however, the argument for the existence of these objects presupposes the existence of God; (III) the argument in favor of the existence of those objects, besides being related to the mentioned circularity, is developed without Berkeley presenting a clear notion of what these objects are; (IV) the argument for the existence of other minds, in what appears to be their most plausible interpretation – which states that it is possible to infer the existence of other minds from the observation of irregular, inconstant, and vicious actions in subjects –, faces the difficulty that, in a scenario where such actions do not exist, Berkeley loses the evidence for the existence of other minds.

In a familiar limerick attributed to Ronald Knox, the narrator asks how a “tree/should continue to be/when there’s no one about in the Quad,” and is subsequently reassured that its continuous existence is guaranteed by God’s being “always about in the Quad” observing it. This is meant to capture Berkeley’s so‐called ‘continuity argument’ for the existence of God, on which the claim that objects exist continuously over time is supposed to entail the existence of a Divine Mind that continuously perceives (...) the ideas that constitute those objects. But the continuity argument is not an uncontroversial one. For one thing, we might ask what divine perception is supposed to be like – does God perceive all of the ideas that we do, and in the same way that we do? And if so, does this mean that God perceives pain – that God suffers? For another thing, we might ask whether Berkeley is entitled to the claim that objects exist continuously to begin with. In this paper, I look at some of the problems associated with the continuity argument, and then present a reading of divine perception that attempts to prevent these problems from arising at the outset.

According to colour irrealism, material objects do not have colour; they only appear to have colour. The appeal of this view, prominent among philosophers and scientists alike, stems in large part from the conviction that scientific explanations of colour facts do not ascribe colour to material objects. To explain why objects appear to have colour, for instance, we need only appeal to surface reflectance properties, properties of light, the neurophysiology of observers, etc. Typically attending colour irrealism is the error theory (...) of ordinary colour judgement: ordinary judgements in which colour is ascribed to a material object are, strictly speaking, false. In this paper, I claim that colour irrealists who endorse the error theory cannot explain how we acquire colour concepts (yellow, green, etc.), concepts they must acknowledge we do possess. Our basic colour concepts, I argue, could not be phenomenal concepts that we acquire by attending to the colour properties of our experience. And, I explain, all other plausible explanations render colour concepts such that our ordinary colour judgements involving them are often true. Given the explanatory considerations upon which the irrealist's position is based, this is a severe problem for colour irrealism. (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.

Discussions of John Locke’s theory of causation tend, understandably, to focus on the related notion of power and in particular the dialectic with David Hume. But Locke faces a very different threat, one that is internal to his view. For he argues both that causation is a relation and that relations are not real. The obvious conclusion is intolerable. And yet the premises, I argue, are unassailable. Building on an interpretation of Locke’s treatment of relations I have developed elsewhere, I (...) show how Locke can at once speak meaningfully of causation and deny its mind-independent existence. (shrink)

It is commonly thought that Hume endorses the claim that causal cognition can be fully explained in terms of nothing but custom and habit. Associative learning does, of course, play a major role in the cognitive psychology of the Treatise. But Hume recognizes that associations cannot provide a complete account of causal thought. If human beings lacked the capacity to reflect on rules for judging causes and effects, then we could not (as we do) distinguish between accidental and genuine regularities, (...) and Hume could not (as he does) carry out his science of human nature. One might reply that what appears to be rule-governed behavior might emerge from associative systems that do not literally employ rules. But this response fails: there is a growing consensus in cognitive science that any adequate account of causal learning must invoke active, controlled cognitive processes. (shrink)

This thesis investigates Hume’s philosophy of external existence in relation to, and within the context of, his philosophy of scepticism. In his two main works on metaphysics – A Treatise of Human Nature (1739–40) and the first Enquiry (first ed. 1748) – Hume encounters a predicament pertaining to the unreflective, ‘vulgar’ attribution of external existence to mental perceptions and the ‘philosophical’ distinction between perceptions and objects. I argue that we should understand this predicament as follows: the vulgar opinion is our (...) natural and default belief for Hume, but causal reasoning reveals it to be false, and the philosophical alternative is a confabulation that we cannot permanently believe and is devoid of justification. Hume uses the fact that we cannot have a satisfactory account of belief in external existence as a sceptical consideration to motivate his wider philosophical scepticism. Hume’s response to his predicament about external existence is found in the context of his confrontation with other sceptical worries (Treatise 1.4.7 and Enquiry 12), in which Hume also reflects generally on the nature and implications of scepticism. I argue that we should characterise Hume’s position as residually sceptical. This means that, while Hume accepts the unanswerability of some sceptical problems, he denies that it is possible to eradicate all belief as a result (and denies that it is practically useful to even try) and instead uses sceptical problems as a motivation to adopt a moderately sceptical position. While we inevitably return to entertaining the vulgar belief, there is no solution to the sceptical predicament; Hume does not endorse the vulgar belief, or the philosophical system, or indeed any alternative system of the external world that might extinguish the predicament. Sceptical doubt, for Hume, does not derail intellectual pursuits, but rather modifies our attitudes in those very pursuits. (shrink)

On the assumption that we may learn from our elders and betters, this paper approaches some fundamental questions in perceptual epistemology through a dispute between McDowell and Wright about external world scepticism.

To the great puzzlement of his readers, Berkeley begins by arguing that nothing exists other than minds and ideas, but concludes by claiming to have defended the existence of bodies. How can Berkeley's idealism amount to such a defense? I introduce resources from Berkeley's philosophy of language, and especially his analysis of the discourse of physics, to defend a novel answer to this question. According to Berkeley, the technical terms of physics are meaningful despite failing to designate any reality; their (...) meaningfulness derives from the useful role they play in organizing and predicting our experience. I argue that Berkeleian bodies have the same status as these theoretical entities: they are mere 'quasi-entities' introduced by our ways of speaking and thinking in order to serve our practical purposes. Berkeley nevertheless considers this to be a defense of the existence of bodies because he endorses a radically deflationary semantics for 'exists.'. (shrink)

In the appendix to his Treatise Hume admits that his philosophy of mind is defective. Reluctantly he asserts that his thought has ensnared him in a labyrinth. Referring specifically to the section in the Treatise on personal identity and the self, the young Scot admits that he is “involv’d in such a labyrinth, that, I must confess, I neither know how to correct my former opinions, nor how to render them consistent.” (Treatise 633) My paper is a critical investigation of (...) this characterization of Hume’s predicament. I argue (1) that at best Hume is facing a dilemma, not a labyrinth, and (2) that the dilemma can be solved, and (3) that the resolution to Hume’s problem can be found in his conception of intelligibility.

Locke’s theory of consciousness is often appropriated as a forerunner of present-day Higher-Order Perception (HOP) theories, but not much is said about it beyond that. We offer an interpretation of Locke’s account of consciousness that portrays it as crucially different from current-day HOP theory, both in detail and in spirit. In this paper, it is argued that there are good historical and philosophical reasons to attribute to Locke the view not that conscious states are accompanied by higher-order perceptions, but rather (...) that conscious states constitute perceptions of themselves.

This thesis evaluates a variety of important modern approaches to the study of the mind/brain in the light of recent developments in the debate about how evidence should be used to support a theory and its constituent hypotheses. Although all these approaches are ostensibly based upon the principles of scientific realism, this evaluation will demonstrate that all of them fall well short of these requirements. Consequently, the more modern, co-evolutionary theories of the mind/brain do not constitute the significant advance upon (...) more traditional theories that their authors take them to be. There are two fundamental elements within my discussion of the relationship between evidence and the constituent hypotheses of a theory. Firstly, I shall demonstrate that the traditional veil-of-perception issue has a wider relevance than that which has historically been attributed to it, since it is the paradigm case of an attempt to construct a two level theory on the basis of evidence tha~ does not adequately support either hypothesis. This interpretation of the issue can be represented by constructing a semantically inconsistent tetrad. It is shown that similar tetrads can be constructed for each of the theories of the mind/brain discussed in this thesis. Secondly, I shall argue that the theories discussed all employ a variety of the bootstrap strategy. This strategy is a relatively recent development in the philosophy of science, which suggests a way in which the same evidence can be used to generate both a general and a specific hypothesis within a theory without violating the constraints of scientific realism. However, I contend that recent use of this strategy in the investigation of mind is largely unsatisfactory as a result of a neglect of structural as well as more informal influences upon the kinds of evidence employed to support the hypotheses contained in the theories. The thesis is divided into three major sections. The first (Section A) discusses the influence of the motivations of the individual theorists upon their arguments and provides a critical discussion of the issues of the veil-of-perception and bootstrapping. The second section (Section B) comprises a detailed examination of a range of modern theories of the mind/brain and critically analyses their success. The final section (Section C) draws together general conclusions and methodological consequences of the detailed analysis of the nature of realism and evidence in the philosophy of mind. (shrink)
