This paper provides support for the unorthodox view that Hume’s simple ideas are most fruitfully understood as theoretical posits by showing that adopting this interpretation solves a lingering interpretive difficulty, the missing shade of blue. The missing shade of blue is thought to pose a serious challenge to the legitimacy of Hume’s copy principle. Thinking of Humean simple ideas as theoretical posits reveals a dialectical mismatch between Hume and his envisioned reader that, once understood, makes it (...) clear that the case holds little sway against the copy principle. The solution developed and defended has some significant advantages over extant solutions. (shrink)

In a recent paper, José Luis Bermúdez argues that Locke's claim that all simple ideas are adequate is inconsistent with other claims he makes in the Essay concerning the nature of such ideas. In particular, Bermúdez argues that Locke is unjustified in claiming that all simple ideas are adequate, because simple ideas of secondary qualities are in fact not. In this paper I argue that Bermúdez has missed an essential aspect of Locke's distinction (...) and has therefore misconstrued his claims. (shrink)

This paper argues that Locke has a representative theory of sensitive knowledge. Perceivers are immediately aware of nothing but sensory ideas in the mind; yet perceivers think of real external substances that correspond to and cause those ideas, and they are warranted in believing that those substances exist (at that time). The theory poses two questions: what warrants the truth of such beliefs? What is it in virtue of which sensory ideas represent external objects and how do (...) they make perceivers think of those objects? Both the epistemic and semantic issues need to be addressed. This paper urges that Locke's basic account of warrant is roughly reliabilist. The causal origin of sensory ideas assures that, in general, sense based beliefs are true. Locke defines the limit of this warrant by the theoretical point that we cannot discuss skeptical doubt without assuming the truthfulness of our perceptual faculty. Turning to the semantic question, the paper argues that ideas are mental modifications or entities. They are not intrinsically representative (satisfiable), but rather represent only by virtue of their causal origin. They merely “track” the presence of substances and their qualities. Ideas nevertheless prompt perceivers to think of their causes. This is roughly because sensory ideas have a specific mental role, namely, to serve as marks for distinguishing substances and their respective qualities for purposes of action. The paper suggests that, for Locke, the challenge posed by the semantic veil of ideas is to explain this externally directed marking function within bounds of his anti‐innatism. But it concludes that his answers to the twin questions fit together reasonably well. (shrink)

Bernard Bolzano offers a criterion of individuation for ideas, according to which ideas are distinct if and only if they represent different objects or are composed differently. It fails to individuate ideas that are both simple and fail to represent, in particular syncategorematic ideas and logical constants. However, Bolzano also provides the means to close this gap. He suggests that we can distinguish ideas if they are not substitutable for each other in propositions, which (...) we can, in turn, distinguish in terms of their truth-values. This paper explicates this suggestion and develops it into an improved individuation criterion for ideas: ideas also are distinct if we cannot replace them for one another in propositions salva veritate.

The idea that there could be spatially extended mereological simples has recently been defended by a number of metaphysicians (Markosian 1998, 2004; Simons 2004; Parsons (2000) also takes the idea seriously). Peter Simons (2004) goes further, arguing not only that spatially extended mereological simples (henceforth just extended simples) are possible, but that it is more plausible that our world is composed of such simples, than that it is composed of either point-sized simples, or of atomless gunk. The difficulty for these (...) views lies in explaining why it is that the various sub-volumes of space occupied by such simples, are not occupied by proper parts of those simples. Intuitively at least, many of us find compelling the idea that spatially extended objects have proper parts at every sub-volume of the region they occupy. It seems that the defender of extended simples must reject a seemingly plausible claim, what Simons calls the geometric correspondence principle (GCP): that any (spatially) extended object has parts that correspond to the parts of the region that it occupies (Simons 2004: 371). We disagree. We think that GCP is a plausible principle. We also think it is plausible that our world is composed of extended simples. We reconcile these two notions by two means. On the one hand we pay closer attention to the physics of our world. On the other hand, we consider what happens when our concept of something—in this case space—contains elements not all of which are realized in anything, but instead key components are realized in different features of the world.

A simple Henkin-style completeness proof for Gödel 3-valued propositional logic G3 is provided. The idea is to endow G3 with an under-determined semantics of the type defined by Dunn. The key concept in u-semantics is that of “under-determined interpretation”. It is shown that consistent prime theories built upon G3 can be understood as u-interpretations. In order to prove this fact we follow Brady by defining G3 as an extension of Anderson and Belnap’s positive fragment of First Degree Entailment Logic.

That consciousness is composed of simple or basic elements that combine to form complex experiences is an idea with a long history. This idea is approached through an examination of our “picture” or conception of consciousness . It is argued that CC commits us to a certain abstract notion of simple experiential events, or simples, and that traditional critiques of simple elements of experience do not threaten simples. To the extent that CC is taken to conform to (...) how consciousness really is, therefore, the concept of simples must be treated in kind. (shrink)

The mutakallimūn, who began to take care of nature as a result of their metaphysical concerns from the early period and with the influence of the dualist and materialist groups, suggested various theories that attempt to explain the structure and functioning of the universe. Over time, many subjects of physics became an indispensable part of Kalām and were used in the proof of the fundamental principles. Thus, in addition to the definition of body (jism), Kalām books began to contain detailed (...) topics such as time, space, movement and distance. After summarizing the definitions of body, which were made by the mutakallimūn, this article will examine the contents of Ibn Kamāl's epistle on ṭafra (leaping), which has many copies with various titles in the Turkish Libraries. In the beginning of the epistle, Ibn Kamāl mentions the descriptions of body suggested by the prominent mutakallimūn, and then, he compares the views of al-Naẓẓām, who believes in the finite division, with atomist mutakallimūn who accept the infinite division. He criticizes the idea of ṭafra with regard to the notion of body in Kalām. After explaining the arguments of both groups with their justifications, he points out the weaknesses of the arguments of each group, as well. In this connection, he revisits the theory of ṭafra, which is, he argues, a mandatory consequence of al-Naẓẓām’s definition of object, as he also reviews the opinions of Quṭb al-Din al-Rāzī in this direction.

The simple model maintains that morally relevant factors combine in a simple, additive way, like weights on a scale. Although intuitive and familiar, this model entails that certain plausible views about particular cases and how morally relevant factors combine and interact therein are false. Shelly Kagan suggests that we could accommodate the relevant views and interactions by rejecting either of two assumptions the simple model makes: that the moral status of an act is determined by the sum (...) of the contributions made by each of the factors relevant thereto (additivity); and that neither the “weight” nor the “valence” of a factor’s contribution can be affected by other factors (atomism). But is there an atomistic option, a way of accommodating the relevant views and interactions by rejecting additivity rather than atomism? I argue that developing an atomistic option requires offering a conception of contribution that renders coherent the particular claims that must be true if there is, indeed, such an option. And I consider whether Rossian pluralism—the locus classicus for the idea of a contributory right-making factor—offers the resources necessary to offer such a conception, and whether it could accommodate the relevant views and interactions other than by rejecting atomism.

We give a simple and direct proof that super-consistency implies the cut-elimination property in deduction modulo. This proof can be seen as a simplification of the proof that super-consistency implies proof normalization. It also takes ideas from the semantic proofs of cut elimination that proceed by proving the completeness of the cut-free calculus. As an application, we compare our work with the cut-elimination theorems in higher-order logic that involve V-complexes.

The idea that “simplicity is a sign of truth”, and the related “Occam’s razor” principle, stating that, all other things being equal, simpler models should be preferred to more complex ones, have been long discussed in philosophy and science. We explore these ideas in the context of supervised machine learning, namely the branch of artificial intelligence that studies algorithms which balance simplicity and accuracy in order to effectively learn about the features of the underlying domain. Focusing on statistical learning (...) theory, we show that situations exist for which a preference for simpler models provably slows down, instead of favoring, the supervised learning process. Our results shed new light on the relations between simplicity and truth approximation, which are briefly discussed in the context of both machine learning and the philosophy of science. (shrink)

The notion of an extended simple region (henceforth ESR) has recently been marshalled in the service of arguments for a variety of conclusions. Exactly how to understand the idea of extendedness as it applies to simple regions, however, has been largely ignored, or, perhaps better, assumed. In this paper we first (§1) outline what we take to be the standard way that philosophers are thinking about extendedness, namely as an intrinsic property of regions. We then introduce an alternative (...) picture (§2), according to which extendedness is extrinsic. In §3 we argue that it matters which way of thinking about extendedness is the right one, since how ESRs behave is sensitive to what extendedness consists in, and various arguments that appeal to ESRs turn out to be unsound if extendedness is extrinsic rather than intrinsic.

Mismatch is a prominent concept in evolutionary medicine and a number of philosophers have published analyses of this concept. The word ‘mismatch’ has been used in a diversity of ways across a range of sciences, leading these authors to regard it as a vague concept in need of philosophical clarification. Here, in contrast, we concentrate on the use of mismatch in modelling and experimentation in evolutionary medicine. This reveals a rigorous theory of mismatch within which the term ‘mismatch’ is indeed (...) used in several ways, not because it is ill-defined but because different forms of mismatch are.distinguished within the theory. Contemporary evolutionary medicine has unified the idea of ‘evolutionary mismatch’, derived from the older idea of ‘adaptive lag’ in evolution, with ideas about mismatch in development and physiology derived from the Developmental Origins of Health and Disease (DOHaD) paradigm. A number of publications in evolutionary medicine have tried to make this theoretical framework explicit. We build on these to present the theory in as simple and general a form as possible. We introduce terminology, largely drawn from the existing literature, to distinguish the different forms of mismatch. This integrative theory of mismatch captures how organisms track environments across space and time on multiple scales in order to maintain an adaptive match to the environment, and how failures of adaptive tracking lead to disease. Mismatch is a productive organising concept within this theory which helps researchers articulate how physiology, development and evolution interact with one another and with environmental change to explain health outcomes.

According to the Simple View of intentional action, I have intentionally switched on the light only if I intended to switch on the light. The idea that intending to is necessary for intentionally -ing has been challenged by Bratman (1984, 1987) with a counter-example in which a videogame player is trying to hit either of two targets while knowing that she cannot hit both targets. When a target is hit, the game finishes. And if both targets are about to (...) be hit simultaneously, the game shuts down. The player knows that she cannot hit both targets, but still she concludes that, given her skills, the best strategy is to have a go at each target at the same time. Suppose she hits target 1. It seems obvious that she has hit target 1 intentionally. But, Bratman argues, she could not have intended to hit target 1. Since the scenario is perfectly symmetrical, had the player intended to hit target 1, she would have also had to intend to hit target 2. But the player knows that she cannot hit both targets.

A study of smooth classes whose generic structures have simple theory is carried out in a spirit similar to Hrushovski 147; Simplicity and the Lascar group, preprint, 1997) and Baldwin–Shi 1). We attach to a smooth class K0, of finite -structures a canonical inductive theory TNat, in an extension-by-definition of the language . Here TNat and the class of existentially closed models of =T+,EX, play an important role in description of the theory of the K0,-generic. We show that if (...) M is the K0,-generic then MEX. Furthermore, if this class is an elementary class then Th=Th). The investigations by Hrushovski and Pillay , provide a general theory for forking and simplicity for the nonelementary classes, and using these ideas, we show that if K0,, where {,*}, has the joint embedding property and is closed under the Independence Theorem Diagram then EX is simple. Moreover, we study cases where EX is an elementary class. We introduce the notion of semigenericity and show that if a K0,-semigeneric structure exists then EX is an elementary class and therefore the -theory of K0,-generic is near model complete. By this result we are able to give a new proof for a theorem of Baldwin and Shelah 1359). We conclude this paper by giving an example of a generic structure whose first-order theory is simple.

In this paper, following an idea of Christophe Chalons.

It follows, in fact, that such sentences must also hold in all forcing extensions of V. In modal terms, therefore, the Maximality Principle is expressed by the scheme $(\lozenge \square \varphi) \Rightarrow \square \varphi$ , and is equivalent to (...) the modal theory S5.

The strongest principle along these lines is $\square MP\!_{\!\!\!\!\!\!_{\!\!_\sim}}$ , which asserts that $MP\!_{\!\!\!\!\!\!_{\!\!_\sim}}$ holds in V and all forcing extensions.

Locke seems to hold that we have knowledge of the existence of external objects through sensation. Two problems face Locke's account. The first problem concerns the logical form of knowledge of real existence. Locke defines knowledge as the perception of the agreement or disagreement between ideas. However, perceiving agreements between ideas seems to yield knowledge only of analytic truths, not propositions about existence. The second problem concerns the epistemic status of sensitive knowledge: How could the senses yield certain (...) knowledge? This essay argues that the key to solving both problems is Locke's claim that simple ideas are all real, adequate, and true. This explains why, on Locke's view, we have certain knowledge through the senses. It also explains how sensitive knowledge can consist in perceiving an agreement between ideas: perceived agreements among simple ideas of sensation are guaranteed to track relations that obtain among really existing things.

This paper explores the idea that many “simple minded” invertebrates are “natural zombies” in that they utilize their senses in intelligent ways, but without phenomenal awareness. The discussion considers how “first-order” representationalist theories of consciousness meet the explanatory challenge posed by blindsight. It would be an advantage of first-order representationalism, over higher-order versions, if it does not rule out consciousness in most non-human animals. However, it is argued that a first-order representationalism which adequately accounts for blindsight also implies that (...) most non-mammals are not conscious. The example of the honey bee is used to illuminate these claims. Although there is some reason to think that bees have simple beliefs and desires, nevertheless, their visually-mediated cognizing is comparable to that of an animal with blindsight. There is also reason to think that the study of blindsight can also help determine how consciousness is distributed in the animal world. (shrink)

Developing a simple test to identify swiftly neonates with sepsis who carry the genetic variant which means that one dose of the recommended antibiotic, gentamicin, will cause the child to become profoundly deaf looks like an admirable objective. The baby needs antibiotics and needs them within 1 hour of admission to the neonatal intensive care unit. Conventional genetic tests take much longer to yield results. The test being trialled produces results in 25 min; a baby who carries the variant (...) can be treated with a different antibiotic. All the test requires is a gentle swab of the baby’s inner cheek. Babies can be treated for potentially fatal sepsis without the risk that the drugs designed to save their lives will cost them their hearing. Parents and healthcare staff are relieved of worry—a great idea? PALOH is not a trial of the safety or efficacy of the test, only to assess how feasible it will be to carry out this test in a busy NICU, without disrupting the care of the baby.

At its core, this exhilarating collection of essays, interviews, and correspondence spanning the years 1988 through 2018, and reaching back a decade or more previous is about the simple concept that ideas matter.

The popularity of rule-consequentialism among philosophers has waxed and waned. Waned, mostly; at least lately. The idea that the morality that ought to claim allegiance is the ideal code of rules whose acceptance by everybody would bring about best consequences became the object of careful analysis about half a century ago, in the writings of J. J. C. Smart, John Rawls, David Lyons, Richard Brandt, Richard Hare, and others.1 They considered utilitarian versions of rule consequentialism but discovered flaws in the (...) view that attach to the wider consequentialist doctrine. In the eyes of many, the flaws were decisive. Brad Hooker has produced brilliant work that unsettles this complacent consensus.2 Over a period of several years he has produced a sustained and powerful defense of a version of rule consequentialism that does not obviously succumb to the criticisms that have been thought to render this doctrine a nonstarter. He acknowledges intellectual debts to Richard Brandt. But Hooker avoid certain excrescences in Brandt’s efforts to conceive of morality as an ideal code of rules. Most notably, Hooker eschews Brandt’s misguided attempt to derive some version of rule utilitarianism from an underlying commitment to some form of contractualism. Moreover, Hooker has worked to articulate a version of rule consequentialism in sufficient detail that one can see how the different parts of the doctrine hang together and how the best version of the..

In the last number of C.Q. Mr. A. D.

I. 51. From that list he will have to with-draw two names, Gow and Campbell. This construction, which Mr. Knox propounds as a novelty, had been suggested (...) by Mr. Gow in C.R. XLIV., pp. 9–10. For my part, I am not ingenious, and that syntactical possibility would no more have occurred to me independently than would Mr. Gow's three renderings of it, two of which are ‘until he sets her vinous breakfast upon a more solid basis’ and ‘until he sets her grapes on toast’; as little could I ever have thought, with Mr. Knox, of ‘the obvious necessity’ for this fox ‘of rest after a heavy meal’; still less of those further inevitable eventualities1 at which he hints with such delicacy in his quotation of Aelian V. 39. In regard to these and all such matters, to my mind ‘it were to consider too curiously to consider so.’ For even in Greek which represented for my ears some such English as ‘until she set him a-breakfastant upon the dries,’ if there was one thing with which I was completely satisfied it was with the Fox as subject; that seemed so perfectly in keeping both with the happy playfulness of the passage and with the richly idiomatic φατ as applied to a graven image of an animal. But from the fact that I criticized Mr. Gow's note it is obvious that I was familiar with his idea. (shrink)

I show how a de se belief ascription such as "Privatus believes that he himself is rich" may be dealt with by means of a scope distinction over and above that one separating de dicto and de re ascriptions. The idea is, roughly, that 'Privatus...himself' forms in this statement a unity, a single "spread" sign that is at the same time in a de re and de dicto position. If so, H-N. Castañeda's contention that the "quasi-indicator" 'he himself' ('she herself', (...) 'it itself') belongs to a "unique, irreducible logical category" of singular terms is, at best, misleading.

In this essay I discuss how I built a cognitive‐robotics lab using inexpensive LEGO® MINDSTORMS™ robot kits. The lab has provided pedagogical and research opportunities for a number of philosophy courses, and I briefly describe the results of those efforts. I also describe how one might build a similar lab. Philosophers need to be more directly involved in the field of robotics. There is much work to do in tidying up the philosophical debris left by the last wave of robotics (...) research, which the researchers have been unwilling or unable to do themselves. The major barriers to participation have been hardware costs and a lack of technical expertise among most philosophers. In recent years, though, these barriers have become less of a problem. At the end, I present some ideas about the kinds of experiments that such kits make possible and how to expand beyond the limitations of the basic LEGO® hardware. (shrink)

This article starts from the assumption that there are various innate contributions to our view of the world and explores the epistemological implications that follow from this. Specifically, it explores the idea that if certain components of our worldview have an evolutionary origin, this implies that these aspects accurately depict the world. The simple version of the argument for this conclusion is that if an aspect of mind is innate, it must be useful, and the most parsimonious explanation for (...) its usefulness is that it accurately depicts the world. There are a number of important criticisms of this argument. These include the idea that evolutionary justifications are circular, that evolved mental content and principles are not necessarily accurate, and that, if the argument is taken seriously, it has some highly dubious consequences. These criticisms necessitate various qualifications to the initial argument. Nonetheless, it is argued that, in some cases, important conclusions can be drawn about the world from an analysis of evolved contributions to our view of the world. An evolutionary approach cannot provide an ultimate justification for any belief; however, in certain circumstances, it supports the conclusion that a given belief is a reasonable first approximation. To the extent that innate content and principles pertain to topics in metaphysics, they can be viewed as a naturalistic source of metaphysical knowledge. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Hume on the Idea of Existence1 Phillip D. Cummins One, the primary, aim of this paper is to understand an argument Hume employed to defend his contention that there is no special or distinctidea ofexistence. This contention he expressedvariouslyin the following passage: The idea ofexistence, then, is the very same with the idea of what we conceive tobe existent. To reflect on any thing simply, and to reflect on (...) it as existent, are nothing different from each other. That idea, when conjoin'd with the idea of any object, makes no addition to it. Whatever we conceive, we conceive to be existent. Any idea we please to form is the idea ofa being; and the idea of a being is any idea we please to form.2 My secondary aim is to understand what the quoted claim amounts to as a characterization of the idea of existence. I am among those who have serious difficulty understanding what precisely Hume is here claiming. Specifically, I am not sure how, if at all, his position on the idea ofexistence fits with other elements ofhis theory ofthought.3 For example, earlier in the Treatise, in "OfAbstract Ideas," Hume argued that under suitable conditions of habituation and linguistic competence, a single simple4 idea could be the idea ofboth a particular object, a line drawn on a particular sheet ofpaper, and a type ofobject, line in general (T 20-24). Further, on the basis of appropriate comparisons, a single simple idea can also be the idea oftwo different quaUties, purple and extended, for example (T 24-25, 34). The former claim is the positive component ofHume's account ofabstract thinking; the latter is the positive component of his position on distinctions of reason. Hume goes out ofhis way to distinguish his position on the idea of existence from his position on distinctions of reason (T 67). As for how it differs, ifat all, from his position on abstract ideas, a matter by no means obvious, Hume says nothing at all. His silence does not preclude speculation on the subject—on the contrary, it makes such speculation unavoidable—but it does give special importance to his brief and puzzhng proof that there is no special or distinct idea of existence. Volume XVII Number 1 61 PHILLIP D. CUMMINS I. Hume's Argument In making his case that we have no distinct idea of existence Hume first insists that we have an idea of existence, appealing to what he regards as an undeniable matter of psychological fact. He writes, There is no impression nor idea ofany kind, ofwhich we have anyconsciousness or memory, thatis not conceiVd as existent; and 'tis evident, that from this consciousness the most perfect idea and assurance ofbeing is deriv'd. (T 66) The argument seems to comprise the following propositions: attending to consciousness and memory reveals that all the perceptions we experience or remember are believed to exist; one cannot beUeve in the existence of something unless one has an idea of existence; therefore, there is an idea ofexistence (being) which in some way is derived from consciousness and memory. Hume next formulates what he calls a dilemma. From hence we may form a dilemma, the most clear and conclusive that can be imagin'd, viz. that since we never remember any idea or impression without attributing existence toit, the idea ofexistence must eitherbe deriv'd from a distinct impression, conjoin'd with every perception or object ofour thought, or must be the very same with the idea of the perception or object. (T 66) The alternatives seem clear: either, in believing in the past existence of, say, a blue spot once seen, one has two ideas, one of the blue spot and a different one of existence, or one has only one idea, which somehow is both the idea of the spot and the idea ofexistence. What is not immediately obvious is why Hume speaks ofa dilemma. From the supposed psychological fact (we never remember any idea or impression without attributing existence to it) and its corollary (we have an idea ofexistence) Hume develops a disjunction (either the idea ofexistence is derived from a distinct impression conjoined with every perception, or...

This Element defends a version of the classical theory of divine ideas, the containment exemplarist theory of divine ideas. The classical theory holds that God has ideas of all possible creatures, that these ideas partially explain why God's creation of the world is a rational and free personal action, and that God does not depend on anything external to himself for having the ideas he has. The containment exemplarist version of the classical theory holds that (...) God's own nature is the exemplar of all possible creatures, and therefore that God's ideas of possible creatures are in some sense ideas of himself. Containment exemplarism offers a monotheism fit for metaphysics, insofar as it is coherent, simple, and explanatorily powerful; and offers a metaphysics fit for monotheism, insofar as it leaves God truly worthy of the unconditional worship which Christians, along with Jews and Muslims, aspire to offer to God.

For the most part, contemporary logicians discuss previous logicians’ ideas from different civilizations and make comments thereon, thus addressing specialists in logic studies. In many education systems, the science philosophy and logic principles do not play a preliminary role. Today, in many education systems the science of philosophical thinking and logic principles should play a preliminary role for rational inferences. Unfortunately, in education systems there is little formal training about the principles of logic and their extraordinary capacity to sharpen (...) the mind with brain experiments, which leads to the attaining of innovative ideas. This is the case especially in engineering institutions, where the students are fed with various mathematical principles, equations and numerical solution methodologies. Although classically almost everybody states that mathematics is based on logic, logical principles are not thought through systematically in education systems.. In this short paper the main purpose is to mention t the logical principles that should be beneficial to the young generation, regardless of whether the interest is in logical sciences or in basic works to arrive at limitless logical conclusions.

November 9, 2009 will mark 20 years since the fall of the Berlin Wall, the monumental event that signaled the beginning of the end of Communism in the former Soviet Union. Yet, why was this collapse of Communism considered final, but the many failures of capitalism are considered temporary and episodic? In _The Idea of Communism_, Tariq Ali addresses this very question. The idea of Communism, argues Ali, was simple and noble. _The Communist Manifesto_, which advocated the creation of (...) a society based on the principle of “from each according to his ability, to each according to his need” rather than a system based on greed and profit, appealed to millions all over the globe. However, Ali argues that the vision of society adumbrated by the founders of Communism was a far cry from what became known as actually existing socialism in the Soviet Union and China. The Communist system that developed ignored Engels’s belief that a workers’ movement and its victory were inconceivable without freedom of the press and assembly. This freedom, Engels insisted, “is the air it needs to breathe. Here, in a thought-provoking re-evaluation, Ali argues that a new form of socialism and global planning is vital to save the planet from capitalist and environmental degradation. (shrink)

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)

'Pain and pleasure are simple ideas, incapable of definition.'In 1757 the 27-year-old Edmund Burke argued that our aesthetic responses are experienced as pure emotional arousal, unencumbered by intellectual considerations. In so doing he overturned the Platonic tradition in aesthetics that had prevailed from antiquity until the eighteenth century, and replaced metaphysics with psychology and even physiology as the basis for the subject. Burke's theory of beauty encompasses the female form, nature, art, and poetry, and he analyses our delight (...) in sublime effects that thrill and excite us. His revolution in method continues to have repercussions in the aesthetic theories of today, and his revolution in sensibility has paved the way for literary and artistic movements from the Gothic novel through Romanticism, twentieth-century painting, and beyond. In this new edition Paul Guyer conducts the reader through Burke's Enquiry, focusing on its place in the history of aesthetics and highlighting its innovations, as well as its influence on many subsequent authors from Kant and Schiller to Ruskin and Nietzsche.

The theory of fast and frugal heuristics, developed in a new book called Simple Heuristics that make Us Smart (Gigerenzer, Todd, and the ABC Research Group, in press), includes two requirements for rational decision making. One is that decision rules are bounded in their rationality –- that rules are frugal in what they take into account, and therefore fast in their operation. The second is that the rules are ecologically adapted to the environment, which means that they `fit to (...) reality.' The main purpose of this article is to apply these ideas to learning rules–-methods for constructing, selecting, or evaluating competing hypotheses in science, and to the methodology of machine learning, of which connectionist learning is a special case. The bad news is that ecological validity is particularly difficult to implement and difficult to understand. The good news is that it builds an important bridge from normative psychology and machine learning to recent work in the philosophy of science, which considers predictive accuracy to be a primary goal of science.
