A philosopher once wrote the following words:If I examine the PTOLOMAIC and COPERNICAN systems, I endeavour only, by my enquiries, to know the real situation of the planets; that is, in other words, I endeavour to give them, in my conception, the same relations, that they bear towards each other in the heavens. To this operation of the mind, therefore, there seems to be always a real, though often an unknown standard, in the nature of things; nor is truth or (...) falsehood variable by the various apprehensions of mankind. Though all human race should for ever conclude, that the sun moves, and the earth remains at rest, the sun stirs not an inch from his place for all these reasonings; and such conclusions are eternally false and erroneous.

In lieu of an abstract, here is a brief excerpt of the content:Hume Studies Volume 30, Number 1, April 2004, pp. 33-50 Constancy, Coherence, and Causality IRA M. SCHNALL According to David Hume, we believe in the existence of an external world because of the phenomena of constancy and coherence (T 1.4.2.18-43; SBN 194-210).1 Hume delineated these two aspects of our sensory experience, and claimed that they influence the imagination in such a way as to generate belief in the existence (...) of unperceived objects, independent of the mind. There is disagreement among philosophers as to the proper way to characterize constancy and coherence and the ways in which they respectively lead us to believe in external objects. The most straightforward account of coherence seems to make it the same as Hume's concept of causality. Yet Hume denies that they are the same ; and commentators disagree as to how to understand Hume's distinction between the two. As to constancy, many philosophers, following H.H. Price,2 have argued that it is really just a special case of coherence, and that its role in generating belief in external objects is the same as that of coherence. There is consequent puzzlement as to why Hume attributed a different, and more important, role to constancy. In an important recent book, Louis E. Loeb has proposed a very interesting two-part solution to this last puzzle: First, Hume is convinced that the commonsense view of the external world is patently false; so he cannot allow that it results from something as reasonable as causal inference. But the way coherence leads to belief in external objects is a form of causal inference. So, Hume wants constancy to lead to belief in external objects in a different, less reasonable way; and he wants constancy to be more important than coherence in leading to belief in the external world. Second, Hume did not realize that constancy is simply a special case of coherence (or causality), because of certain assumptions about causality that he Ira M. Schnall is at the Department of Philosophy, Bar-Ilan University, Ramat-Gan, Israel 52900. e-mail: [email protected] 34 Ira M. Schnall had inherited from his predecessors (i.e., he did not see the causality involved in the relation between an object's existing at one moment and its existing at a later moment). Therefore he appealed to non-rational mechanisms of the imagination to explain how constancy leads us to posit external objects.3 I will try to show that solutions such as Loeb's, which grant the affinity between coherence and causality and the reducibility of constancy to coherence, are unnecessary. I will propose a way to make sense of Hume's claim that coherence is not the same as causality; and I will argue that what Hume calls 'constancy' is not, and should not be, the same as, or reducible to, coherence. After introducing some basic terms, including 'constancy' and 'coherence' themselves (in section I), I will discuss the proper characterization of coherence and how it differs from causality (section II). Then I will discuss Hume's account of constancy and how it leads to belief in external obj ects; and I will contrast it with the alternative account, referred to above, that is widely held to be preferable (section III). I will argue that Hume's own account has certain advantages over the alternative (section IV) and that the main arguments against Hume's account are inconclusive (sections V and VI). The argument of section IV will yield an explanation of Hume's assigning more importance to constancy than to coherence. Finally, I will suggest (in the concluding section) that though Hume considered constancy and coherence to be merely the psychological "causes" that "induce us to believe in the existence of body," we can use them as a basis of an epistemological justification of our belief in the external world. I will make extensive use of H. H. Price's Hume's Theory of the External World; for much of the current understanding, as well as misunderstanding, of Hume's concepts of constancy and coherence is the result of the detailed analyses and arguments in that work.4 I First of...

Immensely intelligible, thought-provoking guide by Nobel prize-winner considers such topics as the distinction between appearance and reality, the existence and nature of matter, idealism, inductive logic, intuitive knowledge, many other subjects. For students and general readers, there is no finer introduction to philosophy than this informative, affordable and highly readable edition that is "concise, free from technical terms, and perfectly clear to the general reader with no prior knowledge of the subject."—The Booklist of the American Library Association.

Thomas Reid, the Scottish natural and moral philosopher, was one of the founding members of the Aberdeen Philosophical Society and a significant figure in the Scottish Enlightenment. Reid believed that common sense should form the foundation of all philosophical inquiry. He criticised the sceptical philosophy propagated by his fellow Scot David Hume and the Anglo-Irish bishop George Berkeley, who asserted that the external world did not exist outside the human mind. Reid was also critical of the theory of ideas propagated (...) by Locke and Descartes, arguing that it was incompatible with physical and experiential facts. For Reid, our senses demonstrate that the external world must exist, and this work is organised in chapters examining each of the senses in turn. The book, based on his lectures, was first published in 1764 when Reid was a regent professor at King's College, Aberdeen, and was reissued in 1818. (shrink)

Much has been written about Kemp Smith's famous problem regarding the tension between Hume's naturalism and his scepticism. However, most commentators have focused their attention on the Treatise; those who address the Enquiry often take it to express essentially the same message as the Treatise. When Hume's scepticism in the Enquiry has been investigated in its own right, commentators have tended to focus on Hume's inductive scepticism in Sections 4 and 5. All in all, it seems that Section 12 has (...) been unduly neglected. This paper seeks to address Kemp Smith's problem from the standpoint of Hume's treatment of scepticism in EHU 12, and finds an interesting internalist account that makes sense both of Hume's discussion in EHU 12, and his aims in the Enquiry as a whole. Moreover, it is one that is of substantive philosophical interest, having intriguing parallels to contemporary epistemological accounts. (shrink)

This article investigates Hume's account of mental transparency. In this article, I will endorse Qualitative Transparency – that is, the thesis that we cannot fail to apprehend the qualitative characters of our current perceptions, and these apprehensions cannot fail to be veridical – on the basis that, unlike its competitors, it is both weak enough to accommodate the introspective mistakes that Hume recognises, and yet strong enough to make sense of his positive employments of mental transparency. Moreover, Qualitative Transparency is (...) also philosophically satisfying in providing good philosophical reason for why the mental states that are incorrigible should in fact be so. (shrink)

The inoffensive title of Section 1.4.7 of Hume’s Treatise of Human Nature, ‘Conclusion of this Book’, belies the convoluted treatment of scepticism contained within. It is notoriously difficult to decipher Hume’s considered response to scepticism in this section, or whether he even has one. In recent years, however, one line of interpretation has gained popularity in the literature. The ‘usefulness and agreeableness reading’ (henceforth U&A) interprets Hume as arguing in THN 1.4.7 that our beliefs and/or epistemic policies are justified via (...) their usefulness and agreeableness to the self and others; proponents include Ardal (in Livingston & King (eds.) Hume: a re-evaluation, 1976), Kail (in: Frasca-Spada & Kail (eds.) Impressions of Hume, 2005), McCormick (Hume Stud 31:1, 2005), Owen (Hume’s reason, 1999), and Ridge (Hume Stud 29:2, 2003), while Schafer (Philosophers, forthcoming) also defends an interpretation along these lines. In this paper, I will argue that although U&A has textual merit, it struggles to maintain a substantive distinction between epistemic and moral justification—a distinction that Hume insists on. I then attempt to carve out the logical space for there being a distinctly epistemic notion of justification founded on usefulness and agreeableness. However, I find that such an account is problematic for two reasons: first, it cannot take advantage of the textual support for U&A; secondly, it is incompatible with other features of the text.

In his Essays on the Intellectual Powers of Man, Thomas Reid offers a barrage of objections to the view, held by David Hume, that conceivability implies possibility. In this paper, I present Reid's first two objections to the ‘maxim of conceivability’ and defend Hume from them. The first objection concerns our ability to understand impossible claims, while the second concerns thoughts about impossible claims (such as, for instance, the thought that they are impossible). Reid's objections have special force against Hume (...) because of his commitment to analyse all operations of the understanding in terms of conception. I argue that these objections fail, on the grounds that they presuppose substantive views about language which we are not warranted in attributing to Hume. Ultimately, Reid's objections help us draw out a set of intertwined issues about the language-mind relationship in Hume. (shrink)

In this compelling analysis David Pears examines the foundations of Hume's theory of the mind as presented in the first book of the Treatise. Past studies have tended to take one of two extreme views: that Hume relies exclusively on a theory of meaning, or that he relies exclusively on a theory of truth and evidence. Steering a middle course between these positions, Pears argues that Hume's theory of ideas serves both functions. He examines in detail its application to three (...) difficult problems: causation, personal identity, and sense perception. Hume's solutions, Pears argues, are not theories that can be given a place in standard classification of philosophical theories, but rather depend upon a subtle form of naturalism not altogether unlike Wittgenstein's naturalism. A clearly written and argued study, Hume's System will be of special interest to students and scholars of the history of philosophy. (shrink)

Hume has traditionally been understood as an inductive sceptic with positivist tendencies, reducing causation to regular succession and anticipating the modern distinctions between analytic and synthetic, deduction and induction. The dominant fashion in recent Hume scholarship is to reject all this, replacing the ‘Old Hume’ with various New alternatives. Here I aim to counter four of these revisionist readings, presenting instead a broadly traditional interpretation but with important nuances, based especially on Hume’s later works. He asked that we should treat (...) these— notably the first Enquiry—as his authoritative philosophical statements, and with good reason. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:33 HOW TO BECOME A MODERATE SKEPTIC: HUME'S WAY OUT OF PYRRHONISM The nature and extent of Hume's skepticism have been assessed in various ways. He was viewed as a radical skeptic until the end of the XIXth century. Many contemporary interpretations, which can be traced back to Kemp Smith's book, have claimed since that a reassessment was indispensable if we are to take seriously either the very project (...) of a science of human nature or Hume's naturalist conception of belief. The idea of a science of human nature presupposes that at least some sort of positive knowledge is possible. The naturalist conception of belief claims that some of our beliefs, though lacking rational justification, are nevertheless unavoidable and gain this way a certainty all their own. Both the Treatise of Human Nature in Book I and the Enquiry Concerning the Human Understanding -1 conclude with a moderate or mitigated skepticism after making a strong case for radical pyrrhonism. In this paper I wish to carry out two connected tasks: first I want to consider whether Hume's skepticism in the Treatise is the same as that of the Enquiry or not; second, I want to determine which arguments he puts forward for his shift from pyrrhonism to modern skepticism. The most noticeable differences between the Treatise and the Enquiry occur immediately after the analysis of causation. In the Enquiry we find almost nothing concerning the reality of the external world and the nature of the self, but Hume emphasizes heavily the 34 anti-metaphysical and anti-theological outcomes of the science of human nature in his sections on Liberty and Necessity (VIII), on Miracles (X), on Providence and a possible future state (XI). He stresses the devastating agnostic consequences of his principles and his agnosticism culminates in the dreadful censorship of the final lines of the book. On the contrary, the fourth part of the Treatise, Book I, offers an intricate and sophisticated treatment of various subjects. The intricacy shows in the very title of this part: "Of the Sceptical and Other Systems of Philosophy." Hume actually intertwines the exposition of his skeptical system — an expression which sounds odd — with the critical examination of rival systems and an attempt at accounting for the nature of things. These intricate undertakings are the direct upshot of Hume's analysis of causation. He thinks he has established that our causal beliefs are the products of custom alone and that nevertheless they are our only reliable beliefs. Lacking any rational justification, they are simply natural — which means that we cannot hinder ourselves from making inferences and predictions. Accordingly, reason has been immersed in the wider concept of imagination and thus naturalized: it is "nothing but a wonderful and unintelligible instinct in our souls" (T 179). Basically, some beliefs are unavoidable. Now, a crucial problem is to know how far we can go into the analysis of such natural beliefs. In the Treatise, Hume sets out to investigate some of them whereas in the Enquiry he is more prudent and merely talks of instincts without considering their mechanism. In the Treatise, the tentative analysis of these natural beliefs has important metaphysical outcomes. Using the concepts and principles of his new-born science of human nature, Hume provides us with 35 a new ontology which states the nature of things from the standpoint of our beliefs concerning it. Thus, we get a Humean version of the nature of the external world and of the nature of the self. Unfortunately, this assessment of what there is on the basis of what we believe there is has unwanted skeptical effects. Hume's "as if" ontology tends to appear definitely fictitious, all the more so because the analysis of our natural beliefs is not successful and even quite defective. So, the skeptical outcome pushes through the positive project itself as the failure to account for our natural beliefs shakes the very belief in their special reliability. Such is, for example, the blatant result of the study of our belief in the external world (T 217). Again, in the Treatise, Hume is eager to emphasize the devastating anti-metaphysical implications of his thought. Under the... (shrink)

Philosophical theories about the nature of belief can be roughly classified into two groups: those that treat beliefs as occurrent mental states or episodes and those that treat beliefs as dispositions. David Hume's A Treatise of Human Nature seems to contain a classic example of an occurrence theory of belief as he defines 'belief' as 'a lively idea related to or associated with a present impression' (Treatise 1.3.7.5 96). This definition suggests that believing is an occurrent mental state, such as (...) judging, or thinking about something in a particular manner. However, a number of Hume's readers claim to find elements in his writings that are suggestive of a dispositional account of belief. Moreover, these elements are sometimes taken as signs of the inadequacy of Hume's account of belief and his dissatisfaction with it. This paper argues that Hume does hold an occurrence theory of belief, that he has deep-seated reasons for doing so, and that this theory of belief has greater explanatory power than its critics generally allow. I contend in particular that beliefs play an explanatory role in Hume's Science of Man that could not be played by dispositions, but requires that beliefs be introspectible occurrent mental states. Attention to the role of belief in explaining our actions, thoughts, emotional responses, and reasoning reveals that Hume is committed to treating beliefs as occurrent states. (shrink)

In this paper I examine whether different suggestions made in the philosophy of perception can help us to explain and understand the phenomenal character of emotional experience. After having introduced the range of possible positions, I consider qualia-theory, reductive pure intentionalism and reductive impure intentionalism. I argue that qualia-theory can easily explain why emotions are phenomenal states at all but that it cannot account for the “inextricable link thesis” which is quite prominent in the philosophy of emotion. Reductive pure and (...) impure intentionalism, in turn, seem to fit better with this thesis but they have difficulties to explain what makes emotions phenomenal states at all. Therefore, I finally discuss whether non-reductive intentionalism might be an option for explaining the phenomenal character of emotional experience. (shrink)

The extreme skepticism that Hume’s dangerous dilemma introduces at the end of the first Book of the Treatise is deeply unsettling, in part because it seems to undermine Hume’s commitments to common life and philosophy, but also because Hume seems not to take its sweeping doubts seriously. He refuses to abandon his daily activities and philosophical pursuits, and he offers no clear account of what entitles him to sustain them. This paper explores a variety of tactics for addressing these opposing (...) elements of his thought. The most radical approach has Hume endorse nothing whatsoever in the Treatise, a maneuver that prevents any conflict between his doubts and his commitments from arising, though at a tremendous cost. A more charitable strategy allows Hume to speak with one consistent voice throughout the text by rejecting, repurposing, or restricting either his doubts or his commitments in a way that resolves the tension between them. Yet a third approach takes Hume to advance incompatible and irreconcilable positions but holds that the inconsistency in his thinking is not as destructive as it initially appears. None of the most promising ways of developing these proposals eliminates or satisfactorily eases the conflict in Hume’s work, and the enormous obstacles that they face give us little reason to hope for something better.

In Book One of the Treatise of Human Nature, Hume seems to acknowledge the existence of both internal and external worlds, in which perceptions, objects, and bodies, exist. In particular, Hume seems directly to affirm the existence of extra-mental bodies, when he says at the beginning of the section "Of scepticism with regard to the senses," "We may well ask, What causes induce us to believe in theexistence of body? but 'tis in vain to ask, whether there be body or (...) not? That is a point, which we must take for granted in all our reasonings" (T 1.4.2.1; SBN 187).1 Furthermore, he thinks that the existence of body must be taken for granted because it is "an affair of too great importance to be trusted to our ..

In A Treatise of Human Nature, Hume seems to use the term "object" to refer to different things in different contexts, including impressions, ideas, perceptions, and bodies. Does he ever use the term "external bodies" to refer to things in the extra-mental world? I argue that what Hume means by external bodies when he affirms their existence is not externally existing, material objects that are somehow presented to the mind or presented in impressions. Rather, the bodies that Hume affirms are, (...) at bottom, no different from perceptions, but they can be distinguished from merely internal perceptions like pain or pleasure in terms of their "different relations, connexions, and durations" (T 1.2.6.9; SBN 68). I conclude that in order to be consistent, given the various statements he makes throughout Book One of the Treatise, Hume must reject the philosopher's doctrine of double existence of perceptions and objects and affirm only the existence of perceptions, sometimes conceived as internally existing and mind-dependent and sometimes conceived as existing outside and independent of the mind. (shrink)

In this paper, I argue that there is a sceptical argument against the senses advanced by Hume that forms a decisive objection to the Metaphysically Realist interpretations of his philosophy – such as the different naturalist and New Humean readings. Hume presents this argument, apparently starting with the primary/secondary qualities distinction, both in A Treatise of Human Nature, Book 1, Part 4, Section 4 (Of the modern philosophy) (1739) and An Enquiry concerning Human Understanding, Section 12 (Of the Academical or (...) Sceptical Philosophy), paragraphs 15 to 16 (1748). The argument concludes with the contradiction between consistent reasoning (causal, in particular) and believing in the existence of Real (distinct and continued) entities. The problem with the Realist readings of Hume is that they attribute both to Hume. So their Hume is a self-reflectively inconsistent philosopher. I show that the various ways to avoid this problem do not work. Accordingly, this paper suggests a non-Realist interpretation of Hume's philosophy: Hume the philosopher suspends his judgment on Metaphysical Realism. As such, his philosophical attitude is neutral on the divide between materialism and idealism. (shrink)

In this article, a novel interpretation of one of the problems of Hume scholarship is defended: his view of Metaphysical Realism or the belief in an external world (that there are ontologically and causally perception-independent, absolutely external and continued, i.e. Real entities). According to this interpretation, Hume's attitude in the domain of philosophy should be distinguished from his view in the domain of everyday life: Hume the philosopher suspends his judgement on Realism, whereas Hume the common man firmly believes in (...) the existence of Real entities. The defended reading is thus a sceptical and Realist interpretation of Hume. As such, it belongs to the class of what can be called no-single-Hume interpretations (Richard H. Popkin, Robert J. Fogelin, Donald L. M. Baxter), by contrast to single-Hume readings, which include Realist (naturalist, New Humean) and the traditional Reid-Green interpretation (i.e. Hume believes that there are no Real entities). Hume's distinction between the domains of philosophy and everyday life, which is argued to be epistemological, is employed in order to reconcile his scepticism with his naturalism and constructive science of human nature. The article pays special attention to the too much neglected second profound argument against the senses in Part 1, Section 12 of Hume's first Enquiry and the corresponding argument in Section 4, Part 4, Book 1 of the Treatise.

Hume's doctrine of natural belief allows that certain beliefs are justifiably held by all men without regard to the quality of the evidence which may be produced in their favour. Examples are belief in an external world and belief in the veracity of our senses. According to R. J. Butler, Hume argues in the Dialogues that belief in God is of this sort. More recently John Hick has argued that for some people it is as natural to believe in God (...) as to believe in an external world. I shall first inquire what Hume understands by reasonable belief and by natural belief. I shall then use the results of this investigation to argue, against Butler, that belief in God is not a natural belief; and against Hick, more briefly, that his thesis is not viable in as far as it depends upon Hume's doctrine of natural belief. These discussions are important to the philosophy of religion since by means of natural beliefs it could be urged that belief in God is something justifiable without reference to reason or evidence: a position which would be of immense value to the theist.

Examines the skeptical arguments in David Hume's major work and analyzes the place of skepticism in his philosophy.

In *Cognition and Commitment in Hume's Philosophy*, Don Garrett argues for the coherence of Hume's philosophy when it is viewed as work in cognitive psychology. Without denying this, I argue that there is more to Hume's standpoint than cognitive psychology. Specifically, Hume's standpoint shifts as the level of inquiry changes. A descriptive cognitive psychology is one standpoint that he occupies. However, he occupies other standpoints as well: the commonsense standpoint of the vulgar is one; the radical doubt of the skeptic (...) is another. Such a radical perspectivism is central to Hume's writings. (shrink)

INTRODUCTION Anyone who reads David Hume's Treatise of Human Nature cannot but be struck by the diversity of philosophical issues Hume addresses, ...

One of the chief problems facing interpreters of Hume's philosophy is what I shall call the integration problem. It is a global problem inasmuch as it casts a shadow on every component of his philosophy, but does not directly affect how we interpret their details. The integration problem arises at the end of Book I of A Treatise of Human Nature, where Hume seemed to acknowledge that his account of human understanding, his logic, leads directly to total skepticism regarding both (...) everyday beliefs and abstruse thought. Nonetheless, he neither reconsidered and repudiated this virulent skepticism nor aborted and disowned his investigation of human nature, the project announced in the Introduction to the Treatise. Instead, he continues with Books II and III, neither of which dwells on or even acknowledges the skepticism with which Book I concludes. The resulting puzzle is not just about his decision to publish the three books as one work, since Hume appears paradoxically to endorse the triumph of skepticism and, yet, continue his pursuit of just the kind of knowledge the triumph of skepticism would entirely preclude. How, one is led to ask, can Hume consistently integrate the destructive skepticism of Book I with the constructive project of explaining and understanding human nature? It is not surprising that a wide range of proposals have been put forward by Hume scholars in response to this question. The crux of every such proposal is specifying how the skepticism of Book I is to be regarded. Is it genuine, a mere facade, or something in between? (shrink)

RÉSUMÉ : Dans le Traité 1.4.4, Hume a présenté au nom des philosophes modernes un argument causal qui démontre que nos impressions des qualités secondaires ne ressemblent pas aux qualités des objets eux-mêmes. Les prédécesseurs de Hume n’ont pourtant pas employé d’argument causal, mais l’argument des qualités contraires. Je soutiens que la présentation qu’en a fait Hume n’est pas simplement à mettre au compte d’une différence stylistique «gratuite» mais est une correction importante dans la foulée de ses propres découvertes philosophiques.
