Hume: Ideas, Misc

Hume’s discussion of space in the Treatise addresses two main topics: divisibility and vacuum. It is widely recognized that his discussion of divisibility contains an answer to Bayle, whose Dictionary article “Zeno of Elea” presents arguments about divisibility as support for fideism. It is not so widely recognized that, elsewhere in the same article, Bayle presents arguments about vacuum as further support for fideism. This paper aims to show that Hume’s discussion of vacuum contains an answer to these vacuum-based fideistic (...) arguments. Key to this answer is a distinction between two ways in which vacuum was conceived in the early modern period: i) as a genuine thing that has spatial properties, and yet is immobile, indivisible, and penetrable ; ii) as a mere absence of spatial things. This paper also aims to provide a novel defense of Hume against the long-standing objection that he is inconsistent in denying that we can conceive of a vacuum, while allowing that we can conceive of “invisible and intangible distance.” As I interpret him, Hume consistently denies that we can conceive of a positive vacuum, while allowing that we can conceive of two or more objects’ being arranged so as to have privative vacuum between them.

Reid’s dilemma concludes that, whether the idea associated with a denied proposition is lively or faint, Hume is committed to saying that it is either believed or merely conceived. In neither case would there be denial. If so, then Hume cannot give an adequate account of denial. I consider and reject Powell’s suggestion that Hume could have advanced a “Content Contrary” account of denial that avoids Reid’s dilemma. However, not only would a Humean Content Contrary account be viciously circular, textual (...) evidence suggests that Hume did not hold such an account. I then argue that Govier’s distinction between force and vivacity cannot help Hume. Not only did Hume fail to recognize this distinction, we can advance a variant of Reid’s dilemma even if we distinguish force from vivacity. (shrink)

El presente trabajo investiga las tesis sobre el poder civil de Alonso de la Veracruz que buscan incorporar en la comunidad política española a los habitantes autóctonos del Nuevo Mundo, tesis que suelen relacionarse con F. de Vitoria y el tomismo español, y que últimamente son consideradas parte del republicanismo novohispano elaborado desde la periferia americana. Se busca demostrar que su propósito era aplicar una teoría de derechos naturales, sin que ello implique participación política de los indios americanos. Se analiza (...) la postura del fraile frente a la diversidad cultural y la guerra contra los indios. The paper explores Alonso de la Veracruz's theses on civil power, which sought to integrate the native inhabitants of the New World into the Spanish political community. These theses, which have usually been associated with F. de Vitoria and Spanish Thomism, have recently come to be considered part of a Novohispanic republicanism developed in the American periphery. The article seeks to show that the purpose of such theses was to apply a theory of natural rights that did not entail the political participation of the indigenous population, as well as to analyze Veracruz's position regarding cultural diversity and the war against the indigenous peoples.

On its face, Hume's account of mental representation involves at least two elements. On the one hand, Hume often seems to write as though the representational properties of an idea are fixed solely by what it is a copy or image of. But, on the other, Hume's treatment of abstract ideas makes it clear that the representational properties of a Humean idea sometimes depend, not just on what it is copied from, but also on the manner in which the mind (...) associates it with other ideas. Past interpretations of Hume have tended to focus on one of these elements of his account to the neglect of the other. But no interpretation of this sort is likely to capture the role that both copying and association play within Hume's discussion. In what follows, I argue that the most plausible way of understanding Hume's discussion involves attributing to him a unified account of mental representation in which both of these elements play a central role. I close by discussing the manner in which reading Hume in this way would alter our understanding of the relationship between Hume's thought and contemporary philosophy of mind. (shrink)

Vivacity, the “liveliness” of perceptions, is central to Hume’s epistemology. Hume equated belief with vivid ideas. Vivacity is a conscious quality so believable ideas are felt to be lively. Hume’s empiricism revolves around a phenomenological, inner epistemology. Through copying, Hume bases vivacity in impressions. Sensory vivacity also concerns liveliness or patterns of change. Through learnt skillful use, it tracks change specific to intentional sense-perceptual experience, Hume’s “coherent and constant” complex impressions. Copying, in turn, communicates the conscious skill of vivacity to (...) ideas where it becomes an indicator of believable ideas. Hume’s copying concerns then the causation of conscious skills required for the identification of empirically warranted structures. Copying allows Hume to combine a radically externalist empiricism with a portable phenomenological inner epistemology. (shrink)

Recent work on Hume's Theory of Perception has shown that Hume takes the appearance of impressions to vary according to the ideas under which they are subsumed. In this paper, I argue that the vulgar position in the section where he discusses the Inference from Constancy is characterised by an ideal primordial state of mind where impressions are directly encountered without being subsumed under any idea. In particular, impressions which are not subsumed under the idea of a perception do not (...) appear to the mind as impressions. Read in this light, Hume's Inference from Constancy is immune to the difficulties which have commonly been raised against it. (shrink)

In this paper, I resolve a potential contradiction between two of Hume's central tenets: that complex perceptions consist of simple perceptions and that distinct things are separable. The former implies that a complex perception is not separable from its constituent simple perceptions, as a change in its constituents destroys its identity. The latter entails that the complex perception is separable from these simple perceptions, since it is distinct from them. This is a contradiction. I resolve it by appealing to a (...) third kind of distinction in addition to the two kinds Hume mentions: real distinctions and distinctions of reason. This third distinction is a partial distinction. I argue that just as the separability principle does not apply to distinctions of reason, neither does it apply to perceptions that are only partially distinct from other perceptions. Hence, the apparent contradiction is resolved. (shrink)

In this paper, I argue that Hume's solution to a problem that contemporary metaphysicians call “the problem of universals” would be rather trope-theoretical than some other type of nominalism. The basic idea in different trope theories is that particular properties, i.e., tropes are postulated to account for the fact that there are particular beings resembling each other. I show that Hume's simple sensible perceptions are tropes: simple qualities. Accordingly, their similarities are explained by these tropes themselves and their resemblance. Reading (...) Hume as a trope nominalist sheds light on his account of general ideas, perceptions, relations and nominalism. (shrink)

Hume's arguments in the Treatise require him to employ not only the copy principle, which explains the intrinsic properties of perceptions, but also a thesis that explains the representational content of a perception. I propose that Hume holds the semantic copy principle, which states that a perception represents that of which it is a copy. Hume employs this thesis in a number of his most important arguments, and his doing so enables him to answer an important objection concerning the status (...) of the copy principle. I further argue that the semantic copy principle is necessary, a priori, and discovered through an analysis of our general idea of representational content. (shrink)

In this paper I aim to investigate Hume's well-known distinction between impressions and ideas, following the methodology of the history of ideas, and showing its specificity and suggesting a possible source, which has not been given much attention by the scholarship, namely the logical doctrines of the physician and anatomist William Harvey, which provide the key concepts to understand Hume's logic of ideas. After some introductory remarks, the second part deals with the many issues involved in Hume's distinction, and in (...) the third part I examine Harvey's logic of ideas. In conclusion I assess Hume's debt to the English physician. (shrink)

In this paper, I argue that Hume has an insight into the heart of most of “new philosophy” when he claims that according to it, proper sensibles are not Real properties of material substance and Real bodies. I call this tenet “the Proper Sensibles Principle” (PSP). In the second part of the paper, I defend the interpretation - mainly against Don Garrett’s doubts - that the PSP is a rational tenet in Hume’s view and he thus endorses it. Its rationality (...) means that the PSP has a firm foundation in inductive-causal reasoning. (shrink)

In the Treatise of Human Nature , Hume argues that, because we have adequate ideas of the smallest parts of space, we can infer that space itself must conform to our representations of it. The paper examines two challenges to this argument based on Descartes's and Locke's treatments of adequate ideas, ideas that fully capture the objects they represent. The first challenge, posed by Arnauld in his Objections to the Meditations , asks how we can know that an idea is (...) adequate. The second challenge, implicit in Locke's Essay , asks how an empiricist can characterize an idea as inadequate, as both picking out an object and yet failing to capture it fully. In showing how Hume responds to these challenges, his theory of perceptual representation is explained and his treatment of space is related to his scepticism. His conclusion is shown not to be a characterization of space as it exists wholly apart from our powers of conception. Instead, in an adumbration of Kant, his claim is restricted to space as it appears to us. (shrink)

La relación entre ideas e imágenes en sus distintas formulaciones filosóficas a lo largo de la modernidad es uno de los elementos clave para la definición de unas y otras, tanto en la teoría epistemológica como en la estética. Este artículo se centra en el estudio de la teoría de las ideas abstractas de Hume, basada en su concepción de las ideas como imágenes. Investigo así sus raíces en la obra de Berkeley, para analizar seguidamente la pretensión humeana de presentar (...) una teoría por completo nominalista. Aquí, el concepto de semejanza, central para la definición de una imagen visual, se revelará como uno de los núcleo de su teoría. The relation between ideas and images, in their different philosophical formulations since the Enlightenment, is one of the key elements of their definitions both in Epistemology as well as in Aesthetics. This paper concentrates on Hume's theory of abstract ideas, based on his conception of ideas as images. I investigate first the roots of his theory in the works of Berkeley, to analyse further Hume's contention that his theory is completely nominalist. Here the idea of similarity, essential for the definition of a visual image, will show itself as the core of his theory. (shrink)

Although Hume has no developed semantic theory, in the heyday of analytic philosophy he was criticized for his “meaning empiricism,” which supposedly committed him to a private world of ideas, led him to champion a genetic account of meaning instead of an analytic one, and confused “impressions” with “perceptions of an objective realm.” But another look at Hume’s “meaning empiricism” reveals that his criterion for cognitive content, the cornerstone both of his resolutely anti-metaphysical stance and his naturalistic “science of human (...) nature,” provides the basis for a successful response to his critics. Central to his program for reforming philosophy, Hume’s use of the criterion has two distinct aspects: a critical or negative aspect, which assesses the content of the central notions of metaphysical theories to demonstrate their unintelligibility; and a constructive or positive aspect, which accurately determines the cognitive content of terms and ideas.

Marc A. Hight has given us a well-researched, well-written, analytically rigorous and thoughtprovoking book about the development of idea ontology in the seventeenth and early eighteenth centuries. The book covers a great deal of material, some in significant depth, some not. The figures discussed include Descartes, Malebranche, Arnauld, Locke, Leibniz, Berkeley, and Hume. Some might think it a tall order for anyone to grapple with the central works of these figures on a subject as fundamental as the nature of ideas. (...) And while reading the book, I must admit to having had this thought a few times. Seventeen pages on Descartes’ theory of ideas, covering the development of his ontology of ideas, the distinction between formal reality and objective reality, the nature of mental representation, the contagion theory of causation, the doctrine of innate ideas as ungrounded dispositions, and the interactionism/occasionalism controversy? Wow. And yet Hight has done his homework. He knows the figures and the relevant interpretive controversies well, he focuses on many of the passages that are relevant to the book’s central thesis, and in the end offers us a compelling narrative as an alternative to what he identifies as “the traditional view of what transpired in the early modern period” (2). (shrink)

The prevailing view about the history of early modern philosophy, which the author dubs “the early modern tale” and wants to convince us is really a fairy tale, has it that the focus on ideas as a solution to various epistemological puzzles, first introduced by Descartes, created difficulties for the traditional ontological scheme of substance and mode. The early modern tale depicts the development of “the way of ideas” as abandoning ontology at least by the time of Berkeley. This, in (...) turn, fostered an antimetaphysical bias as modern philosophy developed further, elevating epistemology to its current primary status in the field. Marc Hight challenges this account by showing how, though the conception of ideas changed over time, the ontological status of ideas remained a central part of the discussion about ideas and influenced how even later thinkers like Locke, Berkeley, and Hume thought about them. By his reading of important texts in early modern philosophy, Hight aims not only to provide a more accurate history of philosophy for this period but also to resuscitate the value of metaphysics for philosophical analysis today.��.

ABSTRACT: In this article I argue that Hume's empiricism allows for time to exist as a real distinct impression of succession, not, as many claim, merely as a nominal abstract idea. In the first part of this article I show how for Hume it is succession and not duration that constitutes time, and, further, that only duration is fictional. In the second part, I show that according to the way Hume describes the functions of the memory and imagination, it is (...) possible to explain how we are able to perceive a distinct impression of succession.RÉSUMÉ: Dans cet article, je soutiens, à l'encontre de plusieurs, que l'empirisme de Hume conçoit le temps comme une impression réelle et distincte de succession, voire, une idée nominale et abstraite. Je montre en premier lieu que Hume définit le temps, non en termes de durée, mais de succession, et que cette notion de durée est fictive. À partir de la description de Hume des fonctions de la mémoire et de l'imagination, je montre en second lieu qu'il est possible d'expliquer comment nous sommes capables d'une impression distincte de succession.

I consider a class of argument implying that Hume's position on general representation is irredeemably circular in that it presupposes what it is meant to explain. Arguments of this sort (the most famous being Sellars' "myth of the given") threaten to undermine any empiricist account of general representation by showing how they depend on the naïve assumption that the relevant resemblances required for the sorting of experience into concepts for use in reasoning are simply given in experience itself. My aim (...) is to salvage Hume's account from this objection. To that end, I argue first for a "Goodmanesque" interpretation of Humean resemblance, and second for an alternative reading of Hume's account of general ideas offered at T 1.1.7 that avoids falling into "the given" trap.

The main problem of this study is David Hume’s (1711-76) view on Metaphysical Realism (there are mind-independent, external, and continuous entities). This specific problem is part of two more general questions in Hume scholarship: his attitude to scepticism and the relation between naturalism and skepticism in his thinking. A novel interpretation of these problems is defended in this work. The chief thesis is that Hume is both a sceptic and a Metaphysical Realist. His philosophical attitude is to suspend his judgment (...) on Metaphysical Realism, whereas as a common man he firmly believes in the existence of mind-independent, external, and continuous entities. Therefore Hume does not have any one position; accordingly, a form of “no one Hume” interpretation (Richard Popkin, Robert J. Fogelin, Donald L.M. Baxter) is argued for in the book. The key point in this distinction is the temporal difference between Hume’s philosophical and everyday views. It is introduced in order to avoid attributing a conscious contradiction to him (a problem which has not attracted enough attention in the literature). The method of the work is modelled on Peter Millican’s work on Hume and induction. The approach to the main problem is to study the two “profound” arguments against the senses that Hume presents in the Section 12 of An Enquiry concerning Human Understanding (1748). These arguments are first reconstructed in detail resulting in Millican-type diagrams of them and then Hume’s endorsement of them is established on the basis of the diagrams. The first profound argument concludes that Metaphysical Realism and thus any Realistic theory of perception is unjustified as well as the existence of God and the soul. The second argument goes further having first conceptual conclusion: the very notions of Real entitity, material substance, and bodies are completely out of the reach of the faculty of understanding. Therefore they ought to be rejected according to Hume. This is a consequence of the consistent use of the Humean faculty of reason: idea-analysis and inductive inference. The second profound argument thus concludes that believing in Metaphysical Realism is inconsistent with the rational attitude that is to refrain from this belief. Hence, if we attributed both of them to Hume, we would end up with a great philosopher who embraces a manifest contradiction. The study is finished by arguing that this sceptical and Metaphysically Realistic interpretation concurs well with (1) Hume’s professed Academical philosophy and (2) project of the science of human nature. (1) According to Hume, Academical philosophy is in the first place diffidence, modesty, and uncertainty including suspension on certain issues. Secondly, it is restriction of the range of topics for which experience can provide a standard of truth. This kind of empiricist epistemological realism is coherent with the sceptical attitude on Metaphysical Realism because the latter does not rule out inter-subjective consensus on what we experience. (2) Suspension of judgment on Metaphysical Realism coheres with the mind-dependency of the objects of Hume’s science of human nature: the understanding, passions, morals, aesthetics, politics, and the human culture in all of its manifestations. Although the study takes the first Enquiry to be Hume’s authorised word on the understanding, his juvenile work A Treatise of Human Nature (1739-40) is argued to support this “no one Hume” interpretation. Hume’s other works are also discussed when needed. (shrink)

This chapter contains section titled: Impressions and Ideas Original and Secondary Impressions Ideas of Memory and Imagination The Copy Principle Simple and Complex Perceptions General Terms References Further reading.

Understanding the distinction between impressions and ideas that Hume draws in the opening paragraphs of his A Treatise on Human Nature is essential for understanding much of Hume's philosophy. This, however, is a task that has been the cause of a good deal of controversy in the literature on Hume. I here argue that the significant philosophical and exegetical issues previous treatments of this distinction (such as the force and vivacity reading and the external-world reading) encounter are extremely problematic. I (...) propose an alternative reading of this distinction as being between original mental entities and copied mental entities. I argue that Hume takes himself to discover this distinction as that which underlies our pre-theoretical sorting of mental entities. Thus, while the Copy Principle is initially treated by Hume as a mere empirical fact, it later comes to play a more substantial explanatory role in his account of human nature. This reading makes Hume's distinction a more philosophically robust one, and avoids many of the exegetical difficulties of previous interpretations. (shrink)

In the Dialogues Concerning Natural Religion, Philo and Cleanthes make use of irregular arguments—arguments whose veracity is founded on the force and vivacity with which they strike the mind. This paper provides an analysis of the irregular arguments by the two characters in the Dialogues and by Hume in the Treatise of Human Nature. Since both characters accept the veracity of irregular arguments, it seems that they are in agreement at the end of the Dialogues. The similarity between their arguments (...) and those Hume presents in the Treatise seem suggests that both characters represent Hume’s actual position. (shrink)

Hume's views on language have been widely misunderstood. Typical discussions cast Hume as either a linguistic idealist who holds that words refer to ideas or a proto-verificationist. I argue that both readings are wide of the mark and develop my own positive account. Humean signification emerges as a relation whereby a word can both indicate ideas in the mind of the speaker and cause us to have those ideas. If I am right, Hume offers a consistent view on meaning that (...) is neither linguistic idealism nor positivism but a genuine alternative to these, one that deserves to be taken seriously. (shrink)

Hume's Copy Principle, which accords precedence to impressions over ideas, is restricted to simple perceptions. Yet in all the conceptual analyses Hume conducts by attempting to fit an impression to a (putative) idea, he never checks for simplicity. And this seems to vitiate the analyses: we cannot conclude from the lack of a preceding impression that a putative idea is bogus, unless it is simple. In this paper I criticise several attempts to account for Hume's seemingly cavalier attitude, and offer (...) one of my own. (shrink)

The examples Hume relies on in _Treatise_ I.iv.2 raise questions about the role of contrariety in experience as it affects belief in the objects of perception.

This essay is on the nature and roles of sense impressions and objects in Hume’s account of perception in the Treatise of Human Nature. I start by considering how Hume introduces sense impressions at the beginning of the Treatise and show that, although he explains the distinction between impressions and ideas on the basis of their different strength and liveliness, the crucial difference between them is in fact that ideas are copies of impressions, while impressions do not, in turn, copy (...) anything. They are what ideas represent, the objects of our thought. But if impressions are non-representative, how can Hume talk about ‘objects’ at all — in fact, what are Humean ‘objects’? This problem is the subject of the present discussion. (shrink)

After arguing that Hume’s judgment on metaphysics is more nuanced than it is usually believed, the relationship between the theory of meaning and the concept, or rather the problem, of “human nature” is analysed in order to underline the relevance of human nature to the explanation of the genesis of meaning and to the extent of the principle of copy, so as to finally examine the relation between meaning and theological discourse.

Hume uses the term 'idea' to refer to both mental acts and mental contents.

Scholars have almost universally agreed that Hume's account of space and time as manners of disposition of impressions is inconsistent with one of the most fundamental tenets of his empiricism: the thesis that all ideas are derived from simple impressions. This paper challenges that view and argues that Hume's position on the origin of our ideas of space and time is a profound, original, virtually unique, and even courageous approach to the problem of original space and time cognition, and a (...) theory that allows for hitherto unrecognized expansions to the resources available to his empiricism.

In lieu of an abstract, here is a brief excerpt of the content:Hume Studies Volume XXIII, Number 2, November 1997, pp. 315-335 Reid: Conception, Representation and Innate Ideas ROGER D. GALLIE Section I of this paper begins with a presentation of Thomas Reid's doctrine of the signification of words, of what words signify or represent. That presentation serves to introduce a problem of interpretation, namely, what Reid thinks the connection is between conceiving something and grasping what a term for it (...) signifies. It is pointed out that even if Reid maintains that what a word signifies is conceived by both speaker and hearer when that word is understood, this is a far cry from the position that he takes the stronger view, whether for all or only for some things, that their being conceived involves the understanding of a term or terms. The position that he does indeed take this stronger, although moderate, view is defended in sections II, III and IV. In sections II and III it is argued that, in Reid's view, for an adequate conception of an individual, real or imaginary, a conception of its attributes is needed. In section IV it is argued that the possession of general conceptions (in distinction from their formation), without which conception of attributes is impossible, requires appropriate understanding of general terms. So since for the conception of an individual a conception of its attributes is needed, and since for the conception of attributes appropriate understanding of general terms is required, we arrive at a textually well-founded position: for the conception of most things, in Reid's view, understanding of terms is indispensable. Roger D. Gallie is at the Department of Philosophy, Nottingham University, University Park, Nottingham NG7 2RD UK. email: [email protected] 316 Roger D. Gallie The remainder of the paper considers the following question: to what extent, if any, Reid is committed to acceptance of nativist views on concept possession? To answer, in section V we consider to what extent Reid's moderate position on the possession of conceptions commits him to accepting Jerry Fodor's representational theory of mind (RTM) for propositional attitudes. It is clear that the view that a propositional attitude state such as belief involves some relation between a person and a representation such as a significant word, phrase or sentence of a natural language such as English can fairly be attributed to Reid. But it is also clear that Reid cannot be an adherent of the view that persons have a functional cum computational relation to Fodorean mental representations, so he cannot be an adherent of any nativism ex- plicitly contained in such a view. But it is to be noted that in his Inquiry, Chapter IV, Reid argues by a different route that in order to acquire a language such as English prior mastery of a system of significant signs is required. In section VI Keith Lehrer's argument in criticism of a reductionist interpretation of a position such as Fodor's is presented: that for a sign to signify something to someone presupposes that that person has a conception of what is signified. It is however pointed out that since there is a case for not viewing Fodor's position as reductionist overall Fodor can accept Lehrer's argument. Lehrer's innatist position, which he both claims to follow easily from this critical argument and to be a correct interpretation of Reid, is then presented: that we must presuppose an innate understanding of some signs to account for our learning the meaning of any signs. The objection that Reid too must accept the alleged innatist implications of Lehrer's critical argument in view of the implications of his moderate position on the possession of conceptions is considered and rebutted. In section VIII argue that while Lehrer makes a respectable case for innate principles of formation of conceptions such as that of hardness, something that Reid clearly endorses in his Inquiry, Chapter V, he does not succeed in making a case for there being any innate possession of conceptions. Finally, in section VIII, Reid's mature views in the Intellectual Powers, Essay VI, on how conceptions come to be possessed are expounded, and are fleshed out with some... (shrink)

Reid thought that the linchpin of his response to\nskepticism was his rejection of the theory of ideas. I\nargue that Reid's assessment of his own work is incorrect;\nthe theory of ideas plays no important role in at least one\nof Berkeley's and Hume's arguments for skepticism, and\nrejecting the theory is therefore neither necessary nor\nsufficient as a reply to that argument. Reid does in fact\nanswer the argument, but with his theory of evidence rather\nthan his rejection of the theory of ideas.

Hume introduced important innovations concerning the theory of ideas. The two most important are the distinction between impressions and ideas, and the use he made of the principles of association in explaining mental phenomena. Hume divided the perceptions of the mind into two classes. The members of one class, impressions, he held to have a greater degree of force and vivacity than the members of the other class, ideas. He also supposed that ideas are causally dependent copies of impressions. And, (...) unlike Locke and others, Hume makes positive use of the principle of association, both of the association of ideas, and, in a more limited way, of the association of impressions. Such associations are central to his explanations of causal reasoning, belief, the indirect passions (pride and humility, love and hatred), and sympathy. These views about impressions and ideas and the principles of association form the core of Hume’s science of human nature. Relying on them, he attempts a rigorously empirical investigation of human nature. The resulting system is a remarkable but complex achievement. (shrink)

The thesis defended is that, for Hume, all vivacity, including that of impressions, is belief, and all belief, including the "infallibility" of the immediate given, is vivacity. This allows one to treat as different axes of description Hume's categories of perception (sensation, reflexion, and thought) and his categories of the consciousness of perception (belief, felt ease of transition), thus making it possible to defend his distinction between impressions and ideas against the criticisms of Ryle, Russell, and others. The article is (...) an excerpt from my forthcoming book, "Hume's Theory of Consciousness" (Cambridge). (shrink)

In lieu of an abstract, here is a brief excerpt of the content:What Impressions of Necessity? Antony Flew My question is this: "Why and how was it that Hume failed to find a kind ofimpression from which to legitimate the complementary ideas of physical necessity and physical impossibility?" We can best begin from his first published discussion of causation. 1. In Treatise 1.3.2, the section, "Ofprobability; and ofthe idea of cause and effect," Hume asserts that, "The idea... of causation must (...) be deriv'd from some relation among objects; and that relation we must now endeavour to discover."1 His first efforts are directed to establishing that two causally related objects must be both spatio-temporally contiguous and temporally successive, the cause object preceding the effect object. But "[h]aving thus discover'd or suppos'd" this conclusion, Hume finds that he is "stopt short, and can proceed no farther in considering any single instance of cause and effect" (T 76). We might, therefore, have expected that his next move wouldhavebeen to consider series ofresemblingcause objects and their relations to series ofresemblingeffect objects. But such a consideration is in fact deferred from section 2 until section 14, "Of the idea of necessary connection"; a section starting all of seventy-seven pages later. Instead, the immediately following paragraph reads: Shou'd any one leave this instance, and pretend to define a cause, by saying it is something productive of another, 'tis evident he wou'd say nothing. For what does he mean by production? Can he give any definition of it, that will not be the same with that of causation? Ifhe can; I desire it maybe produc'd. If he cannot; he here runs in a circle, and gives a synonimous term instead ofa definition. (T 77) The phrasing ofthat paragraph perhaps constitutes one of those infelicities in the Treatise which Hume was later to recognize and regret. For if and inasmuch as "causation" and "production" are synonyms, any adequate definition of either word must be equally adequate for both. Rashly assuming that his challenge toproduce such a definition will not and cannot be met, Hume proceeds at once to ask and to answer his own consequential question: Volume XVIII Number 2 169 ANTONY FLEW Shall we then rest contented with these two relations of contiguity and succession, as affording a compleat idea of causation? By no means. An object may be contiguous and prior to another, without being consider'd as its cause. There isa necessaryCONNEXION to be taken into consideration; and that relation is of much greater importance, than any of the other two above-mention'd. (T 77) 2. But now, why "necessary connexion" rather than either "causal connexion" or "connexion" without prefix or suffix? Suppose that you were the Adam of the Abstract "created in the full vigour of understanding," yet altogether "without experience." (T 650). And suppose that you had noticed some A's both spatio-temporally contiguous to and precedent to B's. Then, assuming that your understanding was not only vigorous but also equipped with all the essential concepts, you might well ask yourself, or perhaps, if she was now available, your partner, whether there was any causal connection here at all; or, more specifically, whether these A's were causing these B's. You might even proceed to put the question to experimental test: either by producing further A's in hopes ofconsequentially producing furtherB's; or, whenA's occurredspontaneously, by trying to inhibit the subsequent occurrence ofB's. What such an Adam would surely not do—not unless he had developed proto-Humean desires: both to demonstrate the absence here ofany logically necessary connections; and thus, hopefully, also to discredit theidea that anyotherkind ofnecessity might beinvolved—is to suggest that the third, crucial, and so far unidentified element in any adequate account of causation must be necessary connection; as opposed, that is, to either causal connection or just plain unqualified connection. It is, of course, obvious that Hume himselfis eager to get on first to denying logically necessary connections, and then to the further business which he relates to this denial. For it is in the immediately followingsection 3, "Whyacauseisalwaysnecessary," thathe presents his argument for the conclusion that, whereas, "Every effectmust... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:A Second Copy Thesis in Hume? George S. Pappas The copy thesis which applies to simple ideas andimpressionsin Hume is well known; every simple idea is supposed to be a copy of, that is, to exactly resemble, some simple impression. Or very nearly so, at any rate, for there is the famous missing shade ofblue to take into account. There seems to be another copy thesis in Hume, however, (...) and one on which Hume places a great deal ofweight. We find it expressed early on in the Treatise, incorporated into Hume's discussion of space and time. He says: Wherever ideas are adequate representations of objects, the relations, contradictions and agreements of the ideas are all applicable to the objects; and this we may in general observe to be the foundation of all human knowledge. But our ideas are adequate representations of the most minute parts of extension; and thro' whatever divisions and subdivisions we may suppose these parts to be arriv'd at, they can never become inferior to some ideas, which we form. The plain consequence is, that whatever appears impossible and contradictory upon the comparison of these ideas, must be really impossible and contradictory, without any farther FogeUn has recently described this as a "remarkable passage," one which is "a match for anything found in the writings of the rationalists."2 Perhaps it is such a match, perhaps not, but Fogelin is certainly right to regard this as a remarkable passage, at least for Hume. After all, Hume here seems to be endorsing some form of representationalism, a doctrine we typically do not associate with Hume's philosophy. Two important questions emerge from this passage:just what are these adequate ideas ofwhich Hume speaks; and, in what sense can it be true that they form the foundation ofall ofour knowledge? I believe that a correct answer to each of these questions has some strong imphcations for our understanding ofHume's philosophy. I. Humean Adequate Ideas So far as I can discover, the above-quoted passage is the Only place where Hume talks about adequate ideas. The only text which I have Volume XVII Number 1 51 GEORGE S. PAPPAS found which even suggests the same sentiments occurs in "Of the Passions" where Hume discusses ideas and truth (T 448-49), but no mention is made there of adequate ideas. So I think we have to concentrate on the passage from the Treatise in the attempt to understand what Hume is telling us. Hume seems to refer to adequacy as a feature ofindividual ideas, and also to groups or systems ofideas. The latter is suggested by his reference to relations, contradictions, and agreements between ideas, while the former is indicated by the first clause ofthe quoted passage, where Hume mentions adequacy but makes no reference to relations between ideas. Instead, adequacy in the relationsbetween ideas seems to be a consequence of adequacy of individual ideas. Moreover, that individual ideas are supposed to be adequate is made clear from the argument Hume immediately gives regarding the alleged infinite divisibility of space. He writes: I first take the least idea I can form ofa part ofextension, and beingcertainthatthereis nothingmoreminute than thisidea, I conclude, that whatever I discover by its means must be a real quality ofextension. (T 29) Hume's reasoning here can be interpreted in two different ways, but both rest on the adequacy of individual ideas. He might be read as saying that one starts with a least-sized idea, and infers that there are bits of extension which are the same size as the least-sized idea. The inference from the feature of the idea to the feature of the bit of extension rests on the claimed adequacy ofthe idea. The other reading of Hume's reasoning is that one starts with the least-sized idea and then infers that there is (a) a bit ofextended matter that small, and (b) that there is no smaller bit of extended matter. Ofthese two readings, I think the second is the right way to understand Hume here, for only it supports the argument's conclusion that space is not infinitely divisible.3 But notice that this second version ofHume...
