In lieu of an abstract, here is a brief excerpt of the content:139 HUME'S "DIALECTIC" Hume's treatment of contradiction in his discussion of external existence has generally been understood to resemble the Pyrrhonian model of dialectic; consequently, Hume has been viewed as a sceptic and an irrationalist. According to that model of dialectic, the sceptic, by showing that equally strong arguments can be constructed both for and against a proposition, raises doubts about the ability of reason to determine the truth (...) or falsity of 2 beliefs. However, I will argue that Hume's treatment of contradiction differs significantly from Pyrrhonian dialectic. I will further argue that his treatment of contradiction is strongly analogous to the Kantian model of dialectic. According to Kant, dialectic is a method which not only shows that reason generates contradictions but which also provides a critique of 3 the logic generating those contradictions. The goal of Kant's dialectic is thus distinctly different from the goal of Pyrrhonian dialectic. For Kant, dialectic is a method for resolving scepticism. The parallels between Hume's treatment of contradiction and Kant's dialectic will suffice to show that Hume's "dialectic" is also a method for resolving, rather than generating, scepticism. Two features of Pyrrhonian dialectic have been deemed relevant for Hume's treatment of contradiction in his discussion of external existence. The Pyrrhonist argues that (1) if equally strong arguments can be given for and against a proposition, it is impossible to assess the truth or falsity of the proposition on the basis of any argument; and (2) if it 140 is impossible to assess rationally the truth or falsity of propositions, we must content ourselves in practical life with following custom and convention in all matters of opinion. Hume describes the contradiction in our belief in external existence as an opposition between two equally natural and unavoidable modes of inference. Both modes of inference are operations of the imagination. Hume does not give a special name to the first of these modes of inference, but he describes it as an "irregular" inference based upon the resemblance A of two distinct mental operations (T 203-204). The second is reflective, or causal, inference based on observation of the constant conjunction of like objects. Causal reasoning is reflective insofar as it is regulated by rules and is, consequently, a check or monitor for judgments resulting from the irregular or unchecked operation of the imagination. These two principles of inference lead to two different judgments about the nature of our perceptions: The imagination tells us, that our resembling perceptions have a continu'd and uninterrupted existence, and are not annihilated by their absence. Reflection tells us, that even our resembling perceptions are interrupted in their existence, and different from each other. (T 215) Just as the Pyrrhonian sceptic maintains that the constructibility of equally strong arguments establishing contradictory propositions makes it impossible to decide which proposition is true, Hume similarly maintains that two opposing modes of inference have an equal influence on the mind and therefore are "unable mutually to destroy each other" (T 215). However, Hume's account of this contradiction would be Pyrrhonian only if he argued that these principles, in addition to being equal in psychological 141 force, also have the same epistemic status. Only their having the same epistemic status makes it impossible to decide rationally whether one of the two principles is a reliable guide for making sound empirical inferences. Popkin, a defender of the Pyrrhonian reading of Hume, maintains that this is just what Hume does argue. Reflection for Hume, he maintains, is no more -a rational principle than is unchecked imagination: There is no rational basis for believing that those objects that have constantly been conjoined in the past, will be so conjoined in the future. It is only custom, or "a certain instinct of our nature," that makes us believe that they will be so conjoined, and this instinct which may be hard to resist psychologically, may well be fallacious and deceitful. The basis for all factual and probable reasoning is thus irrational. 5 If reflection is as irrational a principle as unchecked imagination, then the opposition between reflection and unchecked imagination would be an opposition between equally irrational principles.

To the question whether Hume believed in mind-independent physical objects (or as he would put it, bodies), the answer is Yes and No. It is Yes when Hume writes “We may well ask, What causes induce us to believe in the existence 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.” However the answer is No after inquiring into the causes of (...) that belief, when he writes, “What then can we look for from this confusion of groundless and extraordinary opinions but error and falsehood? And how can we justify to ourselves any belief we repose in them?” My view is that Hume’s Yes and No answers can best be accounted for by seeing him as a Pyrrhonian skeptic in the tradition of Sextus Empiricus. This interpretation, while finding considerable truth in the various positions canvassed, is closest to those of Norton, Fogelin, and especially Popkin. (shrink)

In this volume--the first, focused study of Hume on time and identity--Baxter focuses on Hume’s treatment of the concept of numerical identity, which is central to Hume's famous discussions of the external world and personal identity. Hume raises a long unappreciated, and still unresolved, difficulty with the concept of identity: how to represent something as "a medium betwixt unity and number." Superficial resemblance to Frege’s famous puzzle has kept the difficulty in the shadows. Hume’s way of addressing it makes sense (...) only in the context of his unorthodox theory of time. Baxter shows the defensibility of that theory against past dismissive interpretations, especially of Hume’s stance on infinite divisibility. Later the author shows how the difficulty underlies Hume’s later worries about his theory of personal identity, in a new reading motivated by Hume’s important appeals to consciousness. Baxter casts Hume throughout as an acute metaphysician, and reconciles this side of Hume with his overarching Pyrrhonian skepticism. (shrink)

In part 1 of Enquiry 12, Hume presents a skeptical argument against belief in external existence. The argument involves a perceptual relativity argument that seems to conclude straightaway the double existence of objects and perceptions, where objects cause and resemble perceptions. In Treatise 1.4.2, Hume claimed that the belief in double existence arises from imaginative invention, not reasoning about perceptual relativity. I dissolve this tension by distinguishing the effects of natural instinct and showing that some ofthese effects supplement the Enquiry’s (...) perceptual relativity argument. The Enquiry’s skeptical argument thus reveals the fundamental involvement of natural instinct in any belief in external existence. (shrink)

This paper traces the systematic connections between the structure of Hume's argument in "Of the Standard of Taste" and the way Kant presents the Antinomy of Taste in his Critique of Judgment. It is argued, however, that although there are striking parallels between the way Hume and Kant formulate their respective antinomies, there are significant differences in the way the two philosophers solve them. For while Hume's approach reflects his scepticism about the place of philosophy in common life, Kant's solution (...) confirms his view that philosophy can effectively correct the errors into which human reason naturally falls.

When we look at a tree, two images of it are formed, one on each of our retinas. Why, then, asks the child or the philosopher, do we not see two trees?1 Thomas Reid offers an answer to this question in the section of his Inquiry into the Human Mind entitled ‘Of seeing objects single with two eyes’. The principles he invokes in his answer serve at the same time to explain why we do occasionally see objects double. In Part (...) I of this essay, I examine the principles Reid uses to explain single and double vision. This part is mostly an exercise in the history of cognitive science, but it raises questions of interest to philosophers along the way. In Part II, I turn to a hard-core philosophical problem raised by double vision, namely, whether double vision constitutes an objection to the direct realist theory of perception, which was one of Reid's main philosophical purposes to promote.

The argument presented on behalf of ‘the slightest philosophy’ by Hume that ‘The table, which we see, seems to diminish, as we remove farther from it: But the real table, which exists independent of us, suffers no alteration’, in contrasting the seen with the real table requires the first relative clause to be defining; but the possibility of identifying tables independently of being seen requires the clause to be non-defining. John P. Wright's objection to Reid's rejoinder is rebutted. A similarly (...) worded argument in Alciphron avoids confusion since Berkeley denies that things like tables can be said in any unqualified sense to be seen. (Published Online February 27 2006).

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)

In lieu of an abstract, here is a brief excerpt of the content:25. HUME'S ANTINOMIES I There are many contradictions in Hume. So much is readily admitted by all Hume scholars. But there is little agreement on what these contradictions show about Hume's thought in general. Many interpretations are based upon the view that Hume's contradictions are signs of his carelessness or lack of thoroughness. He is seen either as having lost all interest in giving a comprehensive or consistent account (...) of human nature or as not having pushed far enough his analysis of the philosophical problems facing him. Other interpretations suggest that Hume, the "skeptic," has recklessly introduced these contradictions in order to confuse us. He is perhaps not altogether serious and is laughing at those who take too serious a view of the "science" of metaphysics and his own contribution 2 to it. Others again argue that the contradictions (or some fundamental class of them) are the consequence of Hume's philosophical presuppositions or his psychological method. Given his particular beliefs and his method, these contradictions had to arise with logical necessity. However, the general opinion seems to be that, if Hume is not to be dismissed as a merely negative skeptic whose philosophy is of no great consequence, he needs to be excused or defended, i.e. his contradictions, which are 4 seen as "inconsistencies," have to be explained away. His discussions of the self, causality, substance, or the relationship of reason and the passions must be, and — it is believed — can be shown not to be contradictory, if all the relevant factors are considered. However, reconstructions of Hume's analysis of the self or causality, for instance, which involve the explaining away of contradictions soon find themselves in a rather peculiar quandary, since they also have to show that Hume's own admissions of the contradictory nature of his analysis is mistaken. Such "defenses" issue only in other 26. accusations, namely that Hume, in addition to not having expressed himself very clearly in his writings, failed to understand them himself when he referred back to them. If only for this reason, I think that interpretations which involve an explaining away or minimizing of the contradictions in Hume are suspect. It is my opinion that Hume needs no such defenses or excuses -- at least not in so far as the most important contradictions are concerned. On the contrary, I believe that Hume can be understood properly, only if we take full account of them. I want in this paper to argue that there is in Hume a fundamental class of contradictions which he believed were neither accidental nor created by his analysis, but were essential characteristics of the human mind. The contradictions uncovered by his analysis can be understood only if they are recognised as one aspect of a more complex problematic. They must have a "deeper" significance for Hume because they are the symptoms of the infirmities... which are common to human nature (T265). These are 'Hume's 7 "antinomies. " In this analysis I have allowed myself to be guided by a more or less Kantian conception of "antinomy" and "antinomical." In fact, I believe that there is a definite similarity between Kant's doctrine of the "Antinomy of Pure Reason" and Hume's "operations" which are equally natural and necessary in the human mind, yet in some circumstances... directly contrary (T266). But the present paper is not so much a sustained comparison of Hume and Kant in this regard as it is an attempt to elucidate the g peculiar nature of several contradictions in Hume. For I believe that, if we have a better understanding of the nature of these contradictions, we will also be able to say something more definite about Hume's theory of mental activity and certain aspects of the relationship of skepticism and naturalism (or: Pyrrhonism and Newtonianism, destructive and constructive side, negative and positive phase, etc.) in his thought. To this end, I shall first 27. explain what I mean by "antinomy" here. Secondly, I shall show in what sense Hume was aware of having discovered something very much like an antinomical dimension in human nature, and, finally, I shall offer some suggestions as to the relevance of this...

Why does Hume think that the "distinct existence" of sensible objects implies their "continu'd existence"? Does Hume have any reason for thinking that objects have an intermittent existence, other than that they lack a "distinct" existence? Why does Hume think that the inference from the "coherence" of our impressions to the continued existence of objects is "at bottom" considerably different from causal reasoning? The answers proposed are, respectively, that perceptually delimited objects would for Hume be causally dependent on being perceived; (...) that Hume's collapse of the object/perception distinction leads him to the view that objects have as "gappy" an existence as our perceptions of them, and that cases of coherence falsify the generalizations that would need to hold for inferences from coherence to qualify as causal reasoning.

In A Treatise of Human Nature Hume wrote a long section titled “Of skepticism with regard to the senses.” The discussion examines two key features of our beliefs about the objects making up the external world: 1. They continue to exist, even when unperceived. 2. They are distinct from the mind and its perceptions. The upshot of the discussion is a graceful sort of intellectual despair:I cannot conceive how such trivial qualities of the fancy, conducted by such false suppositions, can (...) ever lead to any solid and rational system... ’Tis a gross illusion to suppose, that our resembling perceptions are numerically the same; and ’tis this illusion, which leads us into the opinion, that these perceptions are uninterrupted, and are still existent, even when they are not present to the senses. This is the case with our popular system. And as to our philosophical one, ’tis liable to the same difficulties; and is over-and-above loaded with this absurdity, that it at once denies and establishes the vulgar supposition. (Treatise, 217-8)These notes examine the argument of this section of the Treatise in detail. The upshot is that Hume’s despair is founded on an error. The notes finish by drawing some lessons about the epistemology of our common-sense world view. (shrink)
