The thesis of underdetermination presents a major obstacle to the epistemological claims of scientific realism. That thesis is regularly assumed in the philosophy of science, but is puzzlingly at odds with the actual history of science, in which empirically adequate theories are thin on the ground. We propose to advance a case for scientific realism which concentrates on the process of scientific reasoning rather than its theoretical products. Developing an account of causal–explanatory inference will make it easier to resist the (...) thesis of underdetermination. For, if we are not restricted to inference to the best explanation only at the level of major theories, we will be able to acknowledge that there is a structure in data sets which imposes serious constraints on possible theoretical alternatives. We describe how Differential Inference, a form of inference based on contrastive explanation, can be used in order to generate causal hypotheses. We then go on to consider how experimental manipulation of differences can be used to achieve Difference Closure, thereby confirming claims of causal efficacy and also eliminating possible confounds. The model of Differential Inference outlined here shows at least one way in which it is possible to ‘reason from the phenomena’. (shrink)

In a series of papers, Schwitzgebel has attempted to revive the dispositionalist account of belief by tweaking it a little and claiming a previously unconsidered advantage over representationalism. The tweaks are to include phenomenal and cognitive responses, in addition to overt behaviour, in the manifestations of a given belief; and to soften the account of dispositions by allowing for dispositional stereotypes. The alleged advantage is that dispositionalism can deal with what Schwitzgebel calls cases of in‐between belief, whereas representationalism cannot. In (...) this paper we argue that Schwitzgebel's attempted improvements do not succeed and that, as an account of belief, dispositionalism is seen to be unsatisfactory. The case for this verdict also enables the representationalist position to be enhanced by drawing attention to the diversity of formats in which beliefs are stored. (shrink)

Davidson argued that the fact we can have a reason for acting, and yet not be the reason why we act, requires explanation of action in terms of the agent's reasons to be causal. The present paper agrees with Dickenson (_Pacific Philosophical Quarterly_, 2007) in taking this argument to be an inference to the best explanation. However, its target phenomenon is the very existence of a case in which an agent has more than one reason, but acts exclusively becaue of (...) one reason. Folk psychology appears to allow for this phenomenon. However, appreciation of 'rationalization' as a form of contrastive explanation reveals the existence of the Davidsonian possibility to the problematic. Claims that 'I did it because of R₁, not because of R₂' are entertained in folk psychology, and may be sincere or insincere. But as reports of conscious practical reasoning, even when sincere, they are not authoritative about the mechanism of motivation. (shrink)

There are two epistemological problems connected with dreaming, which are of different kinds and require different treatment. The internal problem is best seen as a problem of rational consistency, of how we can maintain all of: Dreams are experiences we have during sleep. Dream-experiences are sufficiently similar to waking experiences for the subject to be able to mistake them for waking experiences. We can tell that we are awake. (1)-(3) threaten to violate a requirement on discrimination: that we can only (...) tell Xs from Ys if there is some detectable difference between Xs and Ys. Attempts to solve the problem by Descartes and Williams are considered. It is suggested that if we take account of levels of epistemic risk, we can use Descartes's criterion of lack of coherence, at least with hindsight - which is the time when we need to use it.

We often explain by citing an absence or an omission. Apart from the problem of assigning a causal role to such apparently negative factors as absences and omissions, there is a puzzle as to why only some absences and omissions, out of indefinitely many, should figure in explanations. In this paper we solve this ’many absences problem’ by using the contrastive model of explanation. The contrastive model of explanation is developed by adapting Peter Lipton’s account. What initially appears to be (...) only a trivial amendment to Lipton’s Difference Condition enables us both to offer a much more satisfactory solution to the ’many absences problem’ than David Lewis did, and also to explain why explanation in terms of absences and omissions should be so common.

George Boolos was one of the most prominent and influential logician-philosophers of recent times. This collection, nearly all chosen by Boolos himself shortly before his death, includes thirty papers on set theory, second-order logic, and plural quantifiers; on Frege, Dedekind, Cantor, and Russell; and on miscellaneous topics in logic and proof theory, including three papers on various aspects of the Gödel theorems. Boolos is universally recognized as the leader in the renewed interest in studies of Frege's work on logic (...) and the philosophy of mathematics. John Burgess has provided introductions to each of the three parts of the volume, and also an afterword on Boolos's technical work in provability logic, which is beyond the scope of this volume.

Since the dawn of Romanticism, artists and intellectuals in Germany have maintained an abiding interest in the gods and myths of antiquity while calling for a new mythology suitable to the modern age. In this study, George S. Williamson examines the factors that gave rise to this distinct and profound longing for myth. In doing so, he demonstrates the entanglement of aesthetic and philosophical ambitions in Germany with some of the major religious conflicts of the nineteenth century. Through readings (...) of key intellectuals ranging from Herder and Schelling to Wagner and Nietzsche, Williamson highlights three crucial factors in the emergence of the German engagement with myth: the tradition of Philhellenist neohumanism, a critique of contemporary aesthetic and public life as dominated by private interests, and a rejection of the Bible by many Protestant scholars as the product of a foreign, "Oriental" culture. According to Williamson, the discourse on myth in Germany remained bound up with problems of Protestant theology and confessional conflict through the nineteenth century and beyond. A compelling adventure in intellectual history, this study uncovers the foundations of Germany's fascination with myth and its enduring cultural legacy. (shrink)

This fourth edition of one of the classic logic textbooks has been thoroughly revised by John Burgess. The aim is to increase the pedagogical value of the book for the core market of students of philosophy and for students of mathematics and computer science as well. This book has become a classic because of its accessibility to students without a mathematical background, and because it covers not simply the staple topics of an intermediate logic course such as Godel's Incompleteness Theorems, (...) but also a large number of optional topics from Turing's theory of computability to Ramsey's theorem. John Burgess has now enhanced the book by adding a selection of problems at the end of each chapter, and by reorganising and rewriting chapters to make them more independent of each other and thus to increase the range of options available to instructors as to what to cover and what to defer.

Berkeley construes his own immaterialist philosophy as facing a serious competitor, namely, what he often termed ‘materialism.’ He tries on several grounds to eliminate materialism from the competition, thus leaving immaterialism as the most plausible metaphysical theory of perception and the external world. In this paper these grounds are explored, and it is found that Berkeley’s method for rational choice between materialism and immaterialism involves consideration of a host of criteria for choice between competitive theories.

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 essay, the author analyses Berkeley’s conformity and inference argument against Locke’s theory of percep tion. Both arguments are not as decisive as traditionally has been perceived and fail to engage in Locke’s actual position. The main reason for this is that Berkeley does not see that Locke’s position is compatible with the non-inferential nature of perceptual knowledge.

A number of commentators on the work of berkeley have maintained that berkeleyan minds are related to ideas by the relation of inherence. Thus, Ideas are taken to inhere in minds in something like the way that accidents were supposed to inhere in substances for the aristotelian. This inherence account, As I call it, Is spelled out in detail and critically evaluated. Ultimately it is rejected despite its considerable initial plausibility.

Central-state materialism is a very strong, but also very exciting theory of mind according to which each mental state is identical with a state of the central nervous system. CSM thus goes considerably beyond early versions of the identity theory of mind, since those early accounts held only that sensations are to be identified with neural events. CSM, by contrast, is a thesis about all mental states; every mental state is held to be a state of the central nervous system. (...) In fact, as we will see shortly, CSM is an even more sweeping thesis than this formulation of it suggests, since it is not concerned simply with mental states.One prominent defender of CSM, David Armstrong, has maintained that CSM can be established by means of a two-step argument.

In lieu of an abstract, here is a brief excerpt of the content:167. ON McRAE' S HUME Professor McRae's interesting paper may be rather naturally divided into two parts. In the first part he explains what he takes Hume's account of time to be; in the second he advances the bold thesis that Hume's account of time, or perhaps of duration, provides a basis or foundation for his more widely discussed remarks on identity, substance, the self, the necessary connections. In (...) what follows I first reconstruct Professor McRae' s paper, and then I raise some problems, perhaps puzzles, about Hume's view on duration, time and fictions. According to McRae, some philosophers (Descartes, Spinoza, Leibniz) distinguish between time and duration, both of which are taken to be perfectly legitimate notions. Hume, by contrast, takes time and duration to be the same, viz., a succession of moments. What philosophers and the vulgar call 'duration' is something quite different, namely a single unbroken stretch of time which is not composed of successive parts. Of duration taken in this latter way, McRae says, Hume has four things to say, all of them negative: (1) we have no idea of duration; (2) no object has duration; (3) there is no such thing as duration; and (4) duration is a fiction. Properly understood as a succession of moments, however, time certainly exists and is thus not a fiction. Moreover, we have the or at least an idea of time, despite the fact that it is obtained without derivation from a precedent impression. And, while no object can be said to have time, Hume will nonetheless allow that objects exist at certain times and perhaps across a time span. In the second part of his paper, Professor McRae distinguishes two types of Humean fictions. The first arises when one idea is confused with another and mis-applied to some object. The second arises when the imagination creates an "idea" in the attempt to resolve a 168. contradiction which comes up when the first fiction is applied to an object. What I have called McRae' s "bold thesis" in the second part of his paper can now be stated. Duration, or the putative idea thereof, is a fiction of the first type, one that is attributed to what Hume calls "steadfast objects." However, such an object can be considered in two ways. One might consider the object at two stages of this duration and, McRae says, "...this will give us the idea of number" (p. 126); or, one might consider in turn a series of objects, each of them supposedly "steadfast," all along supposing that though time is changing, the objects are not, and "...in this way- we get the idea of unity" (Ibid.). But no object is both a unity and a multiplicity. So, to reconcile these conflicting considerations, the "idea" or fiction of identity is invented. As McRae says: "The idea of identity is a pure product of the imagination invented to mediate between unity and number" (Ibid. ). This invented "idea" is then mis-applied (a fiction of type one) to interrupted appearances of an object. To reconcile the supposed identity of an object with successive appearances of it, the fiction of substance is invented. Quoting both McRae and Hume, In order to reconcile the contradiction between identity and diversity, the imagination is apt to feign something unknown and invisible, which it supposes to continue the same under all these variations ; 2 and this unintelligible something it calls a substance... (p. 128). Related needs to resolve contradictions, on McRae' s account, lead to the fictions of the self (p. 128) and of necessary connections (p. 130), though the latter fiction is of type one. Hence, McRae' s "bold thesis" amounts to this: Duration is a fiction. In the attempt to apply this fiction, one is led to, logically led to, most, if not all, of the other famous Humean fictions. And, if we allow that there are mental acts, for Hume, as well as impressions and ideas, "...then a fictitious duration will be attributed to 169. objects and by a progressive compounding of fictitious mental actions will give the world the ontological structure which it has for the vulgar belief we all share. It... (shrink)

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)

In lieu of an abstract, here is a brief excerpt of the content:Perception of the Self George S. Pappas Differences of detail aside, we may think ofboth Locke and Berkeley as accepting the same view of the mind. They agree that there are minds, and that each mind is a simple, immaterial substance. Sometimes the word 'soul' is used instead of'mind'; but in this context, the different terminology is not consequential. Moreover, Locke and Berkeley employ essentially the same argument (...) for their shared view about minds. More exactly, they use the same argument for the limited thesis that there is something distinct from perceptions and from ideas perceived, and that this somethingis aperceiver, or that which perceives. The argument, given in more detail below, claims that we are aware ofour own minds in, or while we are engaged in, perception. The kind ofawareness is said to be or to involve a reflex act, a concept we associate with Berkeley, though I think it is one he appropriated from Locke. Hume, ofcourse, rejects the view ofLocke and Berkeley. He rejects the very notion of an immaterial mind or soul, finding it to be meaningless. And he rejects as well the limited thesis that there is something which perceives and which is distinct from all perceptions. In this paper I will restrict attention to Hume's arguments for rejecting the limited thesis. 1. Rejection ofthe limited thesis Hume investigates the limited thesis of Locke and Berkeley in the well-known section ofthe Treatise which deals with personal identity (Treatise 1.4.6). Here is how he expresses the view of "some philosophers": Theke are some philosophers, who imagine we are every moment intimately conscious of what we call our SELF; that we feel its existence and continuance in existence; and are certain, beyond the evidence of a demonstration, both of its perfect identity and simplicity. The strongest sensation, the most violent passion, say they, instead of distracting us from this view, only fix it the more intensely, and make us consider their influence on selfeither by their pain or pleasure.1 Thus, Hume represents the argumentofthosehe opposes as containing two premises: Volume XVIII Number 2 275 GEORGE S. PAPPAS (1)In perception, one is aware ofone's self, and aware ofthe simplicity of the self. (2)In being thus aware of the self and its simplicity one gains an idea of a simple self. These premises, in turn, support a double conclusion: (3)There are simple selves (minds). (4)We have an idea of a simple self(mind). Hume does not take the trouble to cite the second premise given here in the passage I have quoted, butitis clear that he has it in mind, since he proceeds directly to a criticism of it. The criticism is quite familiar inform, encapsulatingwhat I call aderivabilityargument. Here is what Hume says: all these positive assertions are contrary to that very experience, which is pleaded for them, nor have we any idea of self, after the manner it is here explain'd. For from what impression cou'd this idea be deriv'd?... It must be some one impression, that givesrise toeveryreal idea. But selfor person is not any one impression, but that to which our severahmpressionsandideas are suppos'd to have areference. Ifany impression gives rise to the idea ofself, that impression must continue invariably the same, thro' the whole course of our lives; since self is suppos'd to exist after that manner. (T 251) He is also sharply critical ofthe first premise. Hume says: when I enter most intimately into what I call myself, I always stumble on some particularperception orother, ofheatorcold, light or shade, love or hatred, pain or pleasure. I never can catch myselfat any time without a perception, and never can observe any thing but the perception. (T 252) So, minimally, Hume's arguments amount to this: (1) is false; hence, we have nogroundforclaiming(3). Similarly, (2) is false, so that we have no ground for claiming (4). Actually, of course, Hume asserts stronger claims, maintaining that (3) and (4) arefalse, and not merely that we lack adequate support forthem. Buttoshowtheirfalsityrequires additional argumentbeyond whatis providedin the above-quoted passages. Here I will not consider those additional arguments, except to note... (shrink)

Antibiotic allergies are commonly reported among patients, but most do not experience reactions on rechallenge with the same agents. These reported allergies complicate management of infections in patients labelled as having penicillin allergy, including serious infections where penicillin-based antibiotics are the first-line (most effective and least toxic) treatment option. Allergy labels are rarely questioned in clinical practice, with many clinicians opting for inferior second-line antibiotics to avoid a perceived risk of allergy. Reported allergies thereby can have significant impacts on patients (...) and public health, and present major ethical challenges. Antibiotic allergy testing has been described as a strategy to circumvent this dilemma, but it carries limitations that often make it less feasible in patients with acute infections or in community settings that lack access to allergy testing. This article provides an empirically informed ethical analysis of key considerations in this clinical dilemma, usingStaphylococcus aureusbacteraemia in patients with penicillin allergies as a case study. We argue that prescribing first-line penicillin-based antibiotics to patients with reported allergies may often present a more favourable ratio of benefits to risks, and may therefore be more ethically appropriate than using second-line drugs. We recommend changes to policy-making, clinical research and medical education, in order to promote more ethically acceptable responses to antibiotic allergies than the status quo. (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...

Philosophical accounts of perception in the tradition of Kant and Reid have generally supposed that an event of making a judgment is a key element in every perceptual experience. An alternative very austere view regards perception as an event containing nothing judgmental, nor anything conceptual. This account of perception as nonconceptual is discussed first historically as found in the philosophies of Locke and (briefly) Berkeley, and then examined in the contemporary work of Chisholm and Alston.
