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)

At the very root of anarchy is a simple idea: social organization without (an) a dominating figure or controller (archos). Though simple, realizing such a form in our daily lives is virtually impossible. Though virtually impossible, this idea, when pursued, is profoundly constructive.

Many empiricists, among them Locke and Hume, make a distinction between simple and complex ideas. Berkeley refuses to do so, because he finds connections—objective connections incompatible with simplicity—even among the ‘simplest’ of ideas. Simple ideas, in his view, are illegitimately abstract.

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.

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.

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.

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.

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.

In the last number of C.Q. Mr. A. D. Knox has drawn up a list of Theocriteans who, he suggests, ‘have all of them made the most elementary mistake’ of failing to consider the possibility at least that it is the Boy, and not the Fox, who is the subject of καθξ in Id. 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)

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.

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. Further, my account is superior to the well-known theories of R. Chisholm and D. Lewis, according to which de se ascriptions state that the believer "directly attributes properties to himself or herself". 1. Introduction 2. Chisholm and Lewis on de se belief ascriptions 3.

Innate ideas are not objective ideas which have ceased to be doubtful. They are not ideas of attributes or modes but rather true realities. Therefore, they are simple, clear, and distinct. These ideas are not possible to analyze. Innate ideas are not conceived when thinking of "something" but when the real world is felt. Therefore, they correspond with objective ideas.

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.

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.

Philosophy has often appropriated the reflexive element of literature disembodying the sensible idea from the text, thus exercising a coercive violence against literature, reduced to a simple epiphenomenon of a meta-literary discourse. Philosophy tends to appropriate the sensitive content of literature as a raw material to be integrated into a broader conceptual framework dissolving, in fact, the tensional truth implicit in the novelistic structure as Lukács put it. Literary experience cannot be reduced to a mere conceptual structure, to a (...) pure speculative form, but must be investigated as a possibility of grasping sensible ideas embodied in the literary space, following a path indicated by Merleau-Ponty. Sensible ideas as literary ideas are given thanks to the textual space as a deforming filter that allows them to be manifested as a singular incarnation, without ever exhausting them in a full manifestation. Literature allows to unsettle the prereflexive dimension thanks to an operative intentionality thus revealing those particular ideas incorporated into the sensible. Two works by Paul Valéry, La soirée avec M. Teste and L’introduction à la méthode de Léonard de Vinci will be examined to test the emergence, flexibility and irradiation of literary ideas in the writing space. In this way we will try to show the narrative modalities of elaboration of an implicit philosophy in literature as the embodiment of sensible ideas in the literary space and, in this way, as the manifestation of an aesthetic logos.

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)

Concentrating on the legacy of David Hume, I discuss the impact of his psychologism on his two most important sharp distinctions: (1) between statements about the relations of ideas and those about matters of fact; and (2) between what is and what ought to be. I argue that his concept of relations of ideas is subject to difficulties like those attending the concept of synonymy in twentieth-century discussions, and also that his psychologism should lead him to say that (...) (1) is not a sharp distinction. I then raise the more difficult question of whether Hume would have said, as Quine does, that normative epistemology is an empirical science but that normative ethics is not. Finally, I discuss the difficulty of presenting naturalistic support for the claim that a scientific theory ought to predict successfully, be comparatively simple, and respect older truths in some degree.

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.

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)

Newton's use of mathematics in mechanics was justified by him from his neo-platonician conception of the physical world that was going along with his «absolute, true and mathematical concepts» such as space, time, motion, force, etc. But physics, afterwards, although it was based on newtonian dynamics, meant differently the legitimacy of being mathematized, and this difference can be seen already in the works of eighteenth century «Geometers» such as Euler, Clairaut and d'Alembert (and later on Lagrange, Laplace and others). Despite (...) their inheritance of Newton's achievements, they understood differently the meaning and use of mathematical quantities for physics, in a way that was more neutral to metaphysics. The continental reception and assimilation of Newton's Principia had indeed occured as its budding onto Leibniz' calculus and a cartesian conception of rationality (spread in particular by the malebranchist disciples of Leibniz). This new thought of the legitimacy of mathematization is clearly at variance with Descartes' identification of physics with geometry, but it nevertheless can be traced back to Descartes' conception of magnitudes, as it was developed and analyzed from the notion of dimension in his Regulæ ad directionem ingenii (in particular, rule 14). This idea can be followed afterwards with further philosophical or mathematical specifications through authors such as Kant, Riemann and others. This inquiry into the original thought of magnitudes, and of physical magnitudes conceived through mathematization, leads us to suggest an extension of meaning for the concept of physical magnitude that puts emphasis on its relational and structural aspects rather than restraining it to a simple «numerically valued» acception. Such a broadening would have immediate implications on our comprehension of «non classical» aspects of contemporary physics in the quantum area and in dynamical systems. (shrink)

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 defining of 'image' as essentially that class of idea to which there is no object corresponding, springs from a commend able desire not to allow analysis to result in an incorrect conceptual multiplication of physical objects or situations. This result would be likely if the thinker succumbed to the temptation to consider that for every idea entertained there is somehow an objective physical situation corresponding. The simple calling of attention to the type of mental state signified by the (...) word 'imagining' is reckoned to be sufficient to guard against this danger. And so it is. But at the same time,- concentration upon this danger may easily lead to the consequent temptation to consider that there are some ideas which have no objects of reference whatever. This is just not the case. The true insight that some ideas have no objective physical situations corresponding to them does not imply that some ideas have no objects of reference unless it be assumed that all situations or states of affairs are physical. But then if this is true there can be no specific meaning at all for the word 'idea' since by it we imply at the very least some distinction from the physical as such; and in this case all attempts to distinguish 'idea' as over against 'object' break down. The presence of this dilemma is enough to demand a re-analysis of the original distinction. (shrink)

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 organizing concept within this theory that helps researchers articulate how physiology, development, and evolution interact with one another and with environmental change to explain health outcomes.

This chapter inquires into an initially rather startling claim Sebastian Rödl makes in his Self-Consciousness and Objectivity (SC&O): that the power of judgment is not a power among other powers, but rather “the power” (p. 60). It traces Rödl’s sophisticated understanding of powers, as presented in SC&O, in terms of a distinction between “simple powers”, such as a pear tree’s power to blossom, on the one hand, and “self-conscious powers”, such as the power of judgment, on the other. Reflection (...) on related distinctions that SC&O makes between forms of explanation and forms of necessity yields the insight that these two kinds of power cannot be kept apart. The chapter discusses various attempts to bring them together in a satisfactory way and concludes with a proposal in which the idea of givenness plays a central role, in such a way that the initially startling claim can be seen to make sense.

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)

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...

A simple introduction to numbers and their meanings.

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)

Rather than a simple transfer of words or texts from one language to another, on the model of the bilingual dictionary, translation has become understood as a translingual act of transcoding cultural material--a complex act of communication. Much recent work on translation in history grows out of interest in the effects of European colonialism, especially within Asian studies, where interest has been driven by the contrast between the experiences of China and Japan, which were never formally colonized, and the (...) alternative examples of peoples without strong, centralized states--those of the Indian subcontinent and the Tagalog in the Philippines--who were colonized by European powers. This essay reviews several books published in recent years, one group of which share the general interpretation that colonial powers forced their subjects to "translate" their local language, sociality, or culture into the terms of the dominant colonial power: because the colonial power controls representation and forces its subjects to use the colonial language, it is in a position to construct the forms of indigenous and subject identity. The other books under review here are less concerned with power in colonial situations than with the fact of different languages, cultures, or practices and the work of "translating" between the two--particularly the efforts of indigenous agents to introduce European ideas and institutions to their respective peoples.

In this paper, following an idea of Christophe Chalons. I propose a new kind of forcing axiom, the Maximality Principle, which asserts that any sentence varphi holding in some forcing extension $V^P$ and all subsequent extensions $V^{P\ast Q}$ holds already in V. 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. In this article. I prove that the Maximality Principle is relatively consistent with ZFC. A boldface version of the Maximality Principle, obtained by allowing real parameters to appear in φ, is equiconsistent with the scheme asserting that $V_\delta \prec V$ for an inaccessible cardinal δ, which in turn is equiconsistent with the scheme asserting that ORD is Mahlo. The strongest principle along these lines is $\square MP\!_{\!\!\!\!\!\!_{\!\!_\sim}}$ , which asserts that $MP\!_{\!\!\!\!\!\!_{\!\!_\sim}}$ holds in V and all forcing extensions. From this, it follows that $0^\#$ exists, that $x^\#$ exists for every set x, that projective truth is invariant by forcing, that Woodin cardinals are consistent and much more. Many open questions remain. (shrink)

Simple extrapolation is the orthodox approach to extrapolating from clinical trials in evidence-based medicine: extrapolate the relative effect size from the trial unless there is a compelling reason not to do so. I argue that this method relies on a myth and a fallacy. The myth of simple extrapolation is the idea that the relative risk is a ‘golden ratio’ that is usually transportable due to some special mathematical or theoretical property. The fallacy of simple extrapolation is (...) an unjustified argument from ignorance: we conclude that the relative effect size is transportable in the absence of evidence to the contrary. In short, simple extrapolation is a deeply problematic solution to the problem of extrapolation. (shrink)
