Hume: Abstract Ideas

This is partly fictional. It is chiefly a reconstruction (not always faithful) of Hume’s fundamental uses of notions of similarity, mostly based on Enquiry. It is the first part (out of four) of a monograph on the evolution of similarity toolmaking. Histories of doctrines are common in our discipline, not so for histories of tools; this is what it’s about. What’s disturbing: I write as if I were talking about the customs and beliefs of ancient tribes instead of real philosophers. (...) Advantages: helps focus on what similarity tools are apt to, I don’t have to worry about my Hume being merely MY Hume; more fun. Here is the thematic layout: 1.1: (very fictional) methodological introduction; page 2. 1.2: on the origin of ideas + missing shade of blue; p. 4. 1.3: the Xenophobia model; p. 12. 1.4: case studies of cognitive trickery; p. 16 : 1.4.1: arguments from experience; p. 17. 1.4.2: the idea of necessary connection; p. 21. 1.4.3: abstract and very general ideas; p. 23. 1.5: conceptual distinctions between used similarity tools and a few comments; p. 29.

Hume is an experimental philosopher who attempts to understand why we think, feel, and act as we do. But how should we evaluate the adequacy of his proposals? This chapter examines Hume’s account from the perspective of interdisciplinary work in cognitive science.

In a recent paper, Karl Schafer argues that Hume's theory of mental representation has two distinct components, unified by their shared feature of having accuracy conditions. As Schafer sees it, simple and complex ideas represent the intrinsic imagistic features of their objects whereas abstract ideas represent the relations or structures in which multiple objects stand. This distinction, however, is untenable for at least two related reasons. Firstly, complex ideas represent the relations or structures in which the impressions that are the (...) objects of their simple components stand. Secondly, abstract ideas are themselves instances of complex ideas. I draw two important conclusions from these facts. Firstly, contra Schafer and Garrett, the Copy Principle, properly emended, constitutes the entirety of Hume's theory of mental representation. Secondly, whereas paradigm examples of complex ideas, e.g. ideas of spatial and temporal complexes, are structured by relations of contiguity, abstract ideas are those complex ideas instead structured by relations of resemblance. As such, they represent their objects not as spatially or temporally contiguous but rather as resembling. (shrink)

in the treatise, hume claims to identify many “fictions of the imagination” among both “vulgar” and philosophical beliefs. To name just a few, these include the fiction of one aggregate composed of many parts,1 the fiction of a material object’s identity through change, and the fiction of a human mind’s identity through change and interruption in its existence. Hume claims that these fictions and others like them are somehow defective: in his words, they are “improper,” “inexact,” or not “strict”. I (...) will argue that this claim conflicts with other commitments.. (shrink)

David Hume’s and later Ludwig Wittgenstein’s views on concepts are generally presented as standing in stark opposition to each other. In a nutshell, Hume’s theory of concepts is taken to be subjectivistic and atomistic, while Wittgenstein is metonymic with a broadly pragmatistic and holistic doctrine that gained much attention during the second half of the 20th century. In this essay, I shall argue, however, that Hume’s theory of concepts is indeed much more akin to the views of Wittgenstein and his (...) epigones than many, including Wittgenstein himself, probably might have suspected. As I try to show, Hume anticipates many themes central to Wittgenstein’s writings on language and meaning, and actually takes initial steps towards both an anti-subjectivistic and anti-atomistic psychology and epistemology.

according to hume’s theory of general representation, we represent generalities by associating certain ideas with certain words. On one prominent understanding of this theory, calling things by one name or another does not represent any real qualities of those things or any real relations between them. This interpretation runs into difficulty when we turn our attention to Hume’s own use of such general terms throughout the Treatise. It would seem that Hume’s own distinctions—such as the impression-idea distinction and simple-complex distinction—require (...) that the items so.. (shrink)

I defend a reading of David Hume’s nominalism that he comes close to Keith Campbell's contemporary trope theory in the specific case of spatial properties. I argue that Hume's view should be construed as classifying spatial properties as Campbellian tropes (particular properties): abstract, particular, determinate and qualitatively simple properties. This has implications for reconstructing Hume's answer to the problem of universals. I argue that Hume’s account of objects resembling each other in respect of spatial properties is grounded in the resemblance (...) of tropes rather than in the resemblance of objects. (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)

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)

Philosophers have often claimed that general ideas or representations have their origin in abstraction, but it remains unclear exactly what abstraction as a psychological process consists in. We argue that the Lockean aspiration of using abstraction to explain the origins of all general representations cannot work and that at least some general representations have to be innate. We then offer an explicit framework for understanding abstraction, one that treats abstraction as a computational process that operates over an innate quality space (...) of fine-grained general representations. We argue that this framework has important philosophical implications for the nativism-empiricism dispute, for questions about the acquisition of unstructured representations, and for questions about the relation between human and animal minds.

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)

In Book I, Part I, Section VII of the Treatise, Hume sets out to settle, once and for all, the early modern controversy over abstract ideas. In order to do so, he tries to accomplish two tasks: (1) he attempts to defend an exemplar-based theory of general language and thought, and (2) he sets out to refute the rival abstraction-based account. This paper examines the successes and failures of these two projects. I argue that Hume manages to articulate a plausible (...) theory of general ideas; indeed, a version of his account has defenders in contemporary cognitive science. But Hume fails to refute the abstraction-based account, and as a result, the early modern controversy ends in a stalemate, with both sides able to explain how we manage to speak and think in general terms. Although Hume fails to settle the controversy, he nevertheless advances it to a point from which we have yet to progress: the contemporary debate over abstract ideas in cognitive science has stalled on precisely this point.

Many believe that George Berkeley and, subsequently, David Hume offer devastating arguments against John Locke's theory of abstract ideas. It is the purpose of this paper to clarify the attacks given a close reading of Locke. It will be shown that many of the arguments of Berkeley and Hume are of a straw man nature and, moreover, that some of their conclusions are actually in accord with Locke.

In lieu of an abstract, here is a brief excerpt of the content:Hume Studies Volume XXVI, Number 2, November 2000, pp. 279-289 Explaining General Ideas JANET BROUGHTON Hume declared himself a scientist of man; his aim was to identify the principles according to which our impressions give rise to our thoughts, beliefs, passions and actions. He took it that there are things about these products of experience that need to be explained, and as a scientist of man he aimed to (...) provide the needed explanation by finding principles that govern the operations of the mind. In what follows I want to consider Hume's account of general ideas, and I want especially to raise the question what it is about them that he wants to explain. In order to see what Hume thinks he should explain about our general ideas, we need first to see what sort of explanatory resources he thinks are available. In the introduction to the Treatise, he proposes to undertake a study of human nature, a study of the particular kind that he calls science of man. He is going to study the human mind using "careful and exact experiments"1 gleaned up from a "cautious observation of human life" as it appears in the "common course of the world" (T xix). The outcome will be the discovery of "principles," and Hume aims to render them "as universal as possible," "explaining all effects from the simplest and fewest causes" (T xvii). By itself this sounds awfully bland. How does it differ from the generalizations any of us might make about human mental life? On one common understanding of Hume, the answer is that he is studying objects we don't ordinarily talk about, using a method of observation we don't ordinarily use. He is studying what Locke called "ideas": the items of which a person is immeJanet Broughton is Associate Professor of Philosophy, University of California, Berkeley, Berkeley, CA 94720-2390, USA. e-mail: [email protected] 280 Janet Broughton diately aware, and which depend on that awareness for their existence. He is studying them by using his power of introspection, the power by which a person may become immediately aware of his own ideas. I have argued elsewhere2 that Hume's term, 'perception,' isn't meant to refer to Lockean ideas but to people's states of mind as we ordinarily understand them: dateable episodes of consciousness of a great many types, including episodes of seeing, touching, smelling, tasting and hearing objects in the world around us. Nor, I have argued, does Hume's "cautious observation of human life" (T xix) invariably or even usually take the form of introspection. Rather, the scientist of man attends to a range of the features of perceptions that we notice from time to time in ordinary life. What distinguishes the activities of the scientist of man from those of the ordinary observer of human mental life is that the scientist of man attends mainly just to this range of features, and reflects upon them in a sustained and systematic way. The features to which he gives his attention are, I believe, these: force and vivacity; content compounded from simple elements; and the kinds of sequences or patterns in which perceptions with such-and-such content having such-and-such force and vivacity occur. Of these three features, the most puzzling by far, I think, is content; I will be exploring aspects of content as I attempt to identify what it is about general ideas that the scientist of man wants to understand. To put it crudely, we must see what Hume thinks impressions already contain if we want to see what it is about general ideas he wants to explain. In the first part of Book I of the Treatise, Hume sets out the basic distinctions and principles upon which he will draw: the distinctions between impressions and ideas, between simple and complex perceptions, between impressions of sensation and those of reflection, and between ideas of memory and of imagination; and the principles that our simple ideas are derived from resembling simple impressions, and that our ideas are associated via relations of resemblance, contiguity and causation. After clarifying the notion of relations, Hume concludes part i by... (shrink)

Berkeley and Hume object to Locke's account of abstraction. Abstraction is separating in the mind what cannot be separated in reality. Their objection is that if a is inseparable in reality from b, then the idea of a is inseparable from the idea of b. The former inseparability is the reason for the latter. In most interpretations, however, commentators leave the former unexplained in explaining the latter. This article assumes that Berkeley and Hume present a unified front against Locke. Hume (...) supplements Berkeley's argument just where there are gaps. In particular, Hume makes explicit something Berkeley leaves implicit: The argument against Locke depends on the principle that things are inseparable if and only if they are identical. Abstraction is thinking of one of an inseparable pair while not thinking of the other. But doing so entails thinking of something while not thinking of it. This is the fundamental objection. (shrink)

Hume propounds the aporetic principle of correspondence betwen impres-sions and ideas, in order to solve the problem of the genesis of the ideas. This principle, which lacks universal validity, reduces the idea to image and deprives it of universality. In this way is postulated a rigorous and uni-versal nominalism, which converts the ideas into non referential unities the same as the Urimpressions (Husserl) and sets aside the possibility of metaphysics.

In lieu of an abstract, here is a brief excerpt of the content:Abstract General Ideas in Hume George S. Pappas Hume followed Berkeley in rejecting abstract general ideas; that is, both of these philosophers rejected the view that one could engage in the operation or activity ofabstraction — a kind ofmental separation ofentities that are inseparable in reality —as well as the view that the alleged products of such an activity — ideas which are intrinsically general — really exist. What (...) has not been clear to commentators on either of these two philosophers has been why they each were so opposed to abstraction and abstract general ideas. The provision of an answer to this question is the main thrust of this paper. The nature of the question should be clarified at the outset. I am notasking the psychological question, whatwere BerkeleyandHume's actual intentions when they were moved to reject abstraction and abstract general ideas. Though I regard this question as one of great interest and importance, I am presently aiming to answer a somewhat different one, viz., what role, what philosophical role, does the rejection of abstraction and abstract general ideas play in the philosophies ofBerkeley and Hume? The answer to this latter question is apt to have some bearing on the right way to answer the first question; but, for present purposes, it is important to keep the two questions distinct. The maincontentionofthe paperis thattherejectionofabstraction and abstract general ideas lies at the very heart of the philosophy of Berkeley, and that pretty much the same may be said for Hume. Berkeley's defense ofa kind ofidealism stands or falls with the success ofhis attack on abstract general ideas, and Hume's critique ofinfinite divisibility in matters pertaining to space and time, along with his destructive critique ofvarious metaphysical notions, crucially depends on the successful denial of abstract general ideas. I. Berkeleyan Idealism Berkeley's most extended treatment of abstract ideas comes in the introduction to the Principles ofHuman Knowledge, first published in 1710. However, since he does not take up the topic in any systematic way later in the same book, nor in the Three Dialogues Between Hylas and Phihnous (1713), it has seemed to many commentators that Berkeley's attack on abstract ideas is a local matter, one having only to do with issues concerning language use and a somewhat isolated criticism of Locke. That this is the wrong way to look at things is Volume XV Number 2 339 GEORGE S. PAPPAS perhaps best indicated by a couple of passages from the Principles. In section 5 ofthat work Berkeley says: If we thoroughly examine this tenet it will, perhaps, be found at bottom to depend on the doctrine of abstract ideas. For can there be a nicer strain of abstraction than to distinguish the existence of sensible objects from there being perceived, so as to conceive them existing unperceived? The tenet Berkeley is here referring to is to the effect that sensible objects such as trees and chairs exist independently ofperception. This allusion is made clear when we notice that in the immediately preceding passage Berkeley says: It is indeed an opinion strangely prevailing among men that houses, mountains, rivers, and in a word all sensible objects, have an existence, natural or real, distinct from their being perceived by the understanding. But, with how great an assurance and acquiescence soever this Principle may be entertained... whoever shall find in his heart to call it in question may... perceive it to involve a manifest contradiction. For, what are the aforementioned objects but the things we perceive by sense? and what do we perceive besides our own ideas or sensations? and is it not plainly repugnant that any one of these, or any combination of them, should exist unperceived? (Principles 4) The claim that sensible objects exist independently ofall perception is the very denial of Berkeley's esse is percipi thesis regarding such objects. For the latter thesis holds that each sensible object is such that it exists if and only if it is perceived. So, in the first-quoted passage from Principles 5, Berkeley is saying that the denial of esse is percipi 'depends on' the doctrine of abstract ideas. Surely, the esse is percipi thesis is part ofthe core ofBerkeley's... (shrink)

In this paper I suggest that the Humean male and Humean female of Hume’s Treatise would have different mental lives due to a great extent to what Hume takes to be the socio-culture in place. Specifically, I show that the Humean male would be incapable but the Humean female would be capable of forming a Humean sex-neutral general idea of man. The Humean male’s inability is not innate but the result of the trauma he experiences when discovering sexuality, reproduction and (...) realizing how insecure a claim of paternity is. The Humean female not having such a traumatic experience is not impaired in the same way. Insofar as she is impaired, it is because in the very same socio-culture she cannot exercise her ability because it would endanger the socio-culture she is expected to partake in. (shrink)

A very material question has been started concerning abstract or general ideas, whether they be general or particular in the mind's conception of them. A great philosopher [Dr. Berkeley] has disputed the receiv'd opinion in this particular, and has asserted, that all general ideas are nothing but particular ones, annexed to a certain term, which gives them a more extensive signification, and makes them recall upon occasion other individuals, which are similar to them. As I look upon this to be (...) one of the greatest and most valuable discoveries that has been made of late years in the republic of letters, I shall here endeavour to confirm it by some arguments, which I hope will put it beyond all doubt and controversy.

In lieu of an abstract, here is a brief excerpt of the content:17. HUME AND ABSTRACT GENERAL IDEAS In his discussion of abstract ideas in the Treatise, Hume offers what "...may... be thought... a plain dilemma, that decides concerning the nature of those abstract ideas..." He states the dilemma in these words: The abstract idea of a man represents men of all sizes and all qualities; which 'tis concluded it cannot do, but either by representing at once all possible sizes (...) and all possible qualities, or by representing no particular one at all. Now it having been esteemed absurd to defend the former proposition, as implying an infinite capacity in the mind, it has been commonly infer'd in favour of the latter; and our abstract ideas have been suppos'd to represent no particular degree either of quality or quantity. (T, 1,1,7,?.18) However, with respect to this dilemma, Hume says: But that this inference is erroneous, I shall endeavor to make appear, first, by proving, that 'tis utterly impossible to conceive any quantity or quality, without forming a precise notion of its degrees: And secondly by showing, that tho' the capacity of the mind be not infinite, yet we can at once form a notion of all possible degrees of quantity and quality, in such a manner at least, as, however imperfect, may serve all the purposes of reflexion and conversation. (T, 1,1,7, p. 18) The second item Hume claims he is about to prove is aimed at the first disjunct of the above-stated dilemma; more specifically, it is aimed at the claim that (1) An abstract idea (e.g., of a man) represents all possible degrees of quantity and quality (in men) only if the human mind is infinite in capacity. To show that (1) is false, Hume offers his own positive account of how ideas which are particular in nature may nevertheless be general in representation, even though the mind's capacity is finite. The first item Hume sets out to prove is aimed at the second disjunct, and conclusion, of the dilemma; it is aimed, that is, at 18. (2)Abstract ideas represent no particular degree of either quantity or quality. In this paper I will be concerned solely with Hume's attack on (2); it is this attack in which Hume says I "place my chief confidence." (T, I, I, 7, p. 24) I_ As stated, (2) is ambiguous, since it might be taken to mean that abstract ideas fail to represent altogether, or that they fail to represent any quantity or quality however construed. But, I believe, Hume means neither of these; he means, instead, that (2a) Abstract ideas represent non-particular, indeterminate degrees of quantity or quality. Now recall that Hume tries to refute (2a) by establishing, as he says, that (3)It is impossible to conceive any quantity or quality without forming a precise notion of its degrees. But how, by establishing (3), would Hume thereby refute or aid in the refutation of (2a)? And, for that matter, how does he support (3)? Hume's case for (3) consists of three arguments, the respective conclusions of which are most pertinent here. He concludes his first argument by saying that (4)...the general idea of a line...has in its appearance in the mind a precise degree of quantity and quality. (T, 1,1,7, p. 19) The conclusion of the second argument is this : (5)An idea is a weaker impression; and as a strong impression must necessarily have a determinate quantity and quality, the case must be the same with its copy or representative.(T, 1,1,7, p. 19) 19. and of the third it is this: (6)Abstract ideas are therefore in themselves individual, however they may become general in their representation. The image in the mind is only that of a particular object, tho' the application of it in our reasoning be the same, as if it were universal.(T, 1,1,7, p. 20) Construed in a fully general way, these conclusions assert that (7)Each idea is determinate with respect to öegree of) quantity and quality. But notice that (7) is not equivalent to, and does not obviously imply, (3). Hence, Hume... (shrink)

The premise of functional meaning is to the effect that the appropriate use of words--the employment of words in accordance with the standard usage--discloses their meaning. In its extreme or radical version the premise is a downright identification of a meaning with an act, or acts, of using words, i.e., with actual occurrences. Since actual occurrences are particulars, this extreme form would appeal to a nominalist who wants to eschew universals, especially in a concern with meaning. But the radical premise (...) is incompatible with the second premise of a dispositional semantics. For the second premise is intended to do justice to the fact that the same word may take care of endless variations of its meaning or, at any rate, of a number which is not limited to particular variations that occur with the act, or acts, of using the word. Accordingly, a dispositional semantics requires a moderate version of the premise of functional meaning. (shrink)
