Intelligent systems are faced with the problem of securing a principled (ideally, veridical) relationship between the world and its internal representation. I propose a unified approach to visual representation, addressing both the needs of superordinate and basic-level categorization and of identification of specific instances of familiar categories. According to the proposed theory, a shape is represented by its similarity to a number of reference shapes, measured in a high-dimensional space of elementary features. This amounts to embedding the stimulus in a (...) low-dimensional proximal shape space. That space turns out to support representation of distal shape similarities which is veridical in the sense of Shepard's (1968) notion of second-order isomorphism (i.e., correspondence between distal and proximal similarities among shapes, rather than between distal shapes and their proximal representations). Furthermore, a general expression for similarity between two stimuli, based on comparisons to reference shapes, can be used to derive models of perceived similarity ranging from continuous, symmetric, and hierarchical, as in the multidimensional scaling models (Shepard, 1980), to discrete and non-hierarchical, as in the general contrast models (Tversky, 1977; Shepard and Arabie, 1979).

The nature and value of autonomy has long been debated in diverse philosophical traditions, including moral and political philosophy. Although the notion dates back to ancient Greek philosophy, it was during the Age of Enlightenment that autonomy drew much attention. Thus, as may be known, moral philosophers tended to emphasize self-regulation, particularly one’s own will to abide by universal moral laws, as the term “autonomy” originates from the Greek words “self” (auto) and “rule” (nomos). In parallel, modern epistemologists supposedly espoused (...) the idea of intellectual autonomy as self-reliance. In this classical view, an intellectually autonomous explorer of knowledge must not depend on a belief that is obtained from another’s testimony, until one can justify it to oneself. However, accompanying the growing focus on the importance of social dimensions of acquiring knowledge and understanding, recent epistemologists have doubted the classical view and have since reconsidered intellectual autonomy from distinct approaches such as social and virtue epistemology. This paper propounds an interpersonal-epistemic approach to intellectual autonomy. First, it is argued that thinking through questioning both individually and with other epistemic peers is an interpersonal-epistemic practice. Second, it is demonstrated that with particular cognitive features inherent within us, an intellectually autonomous person must think through questioning in necessary situations. This interpersonal account of intellectual autonomy can conceptually enrich intellectual autonomy by considering its relationship with not only responsibility but also with vulnerability. Specifically, regarding responsibility, an intellectually autonomous person must be responsible for his or her own actions throughout questioning processes. Regarding vulnerability, our intellectual autonomy lies in retaining autonomy with vulnerability in the plastic control of the questioning processes. (shrink)

This book introduces the reader to Whitehead’s complex and often misunderstood metaphysics by showing that it deals with questions about the nature of causation originally raised by the philosophy of Leibniz. Whitehead’s philosophy is an attempt at rehabilitating Leibniz’s theory of monads by recasting it in terms of novel ontological categories.

This volume aims to establish the starting point for the development, evaluation and appraisal of the phenomenology of mathematics.

Se buscará mostrar que las críticas de Berkeley son pertinentes al mostrar que Newton utiliza una justificación que se bása en: 1) La experiecia sensible y 2)En una noción de Dios como poder activo.

Con respecto a 2) Dios es una fuente de justificación posbile para la época, sin embargo (...) en Newton se convierte en un poder activo que se contrapone a otras fomas de entender a Dios como garante de las leyes, más no como un poder que intervenga en el mundo.

This chapter outlines an alternative interpretation of Hume’s philosophy, one that aims, among other things, to explain some of the most perplexing puzzles concerning the relationship between Hume’s skepticism and his naturalism. The key to solving these puzzles, it is argued, rests with recognizing Hume’s fundamental irreligious aims and objectives, beginning with his first and greatest work, A Treatise of Human Nature. The irreligious interpretation not only reconfigures our understanding of the unity and structure of Hume’s thought, it also provides (...) a radically different picture of the way in which Hume’s philosophy is rooted in its historical context. By altering our understanding of the fundamentals of Hume’s philosophy in this way, the irreligious interpretation also challenges the adequacy of the familiar and entrenched framework of “British Empiricism.”.

This paper examines what exactly amounts to the view commonly known as ‘perspectivism’, sometimes also known as ‘perspectivalism’. Of the various possible conceptions of perspectivism, four are singled out for closer inspection. Each makes clearly separable claims of varying strength. Their strength is judged against how much doubt they throw on key claims made by the view’s presumed arch-nemesis, namely realism. It is argued that the first two offer no serious challenge to realism. To be precise, it is argued that (...) the first one is blatantly false, while the second is true but utterly harmless. Things are less clear cut with the other two conceptions of perspectivism. If true, they appear to present a more serious challenge to realism. It is argued that considerable doubts hang over their truth as to date arguments raised in their support are far from compelling. Even so, these conceptions cannot be summarily dismissed. Indeed, under more reasonable construals, they need not be for realism to survive and thrive. This is because claims these conceptions make in the name of perspectivism turn out to be easily coupled with realism. (shrink)

The question I wish to explore is this: Does idealism conflict with common sense? Unfortunately, the answer I give may seem like a rather banal one: It depends. What do we mean by ‘idealism’ and ‘common sense?’ I distinguish three main varieties of idealism: absolute idealism, Berkeleyan idealism, and dualistic idealism. After clarifying what is meant by common sense, I consider whether our three idealisms run afoul of it. The first does, but the latter two don’t. I conclude that while (...) Moore’s famous common sense critique is sound against external world skepticism, against Berkeleyan idealism and dualist idealism it is unavailing. (shrink)

Do the hard problem of consciousness and the simulation argument potentially resolve each other? Here we will argue for four possible views: that consciousness may be possible only (a) outside of, (b) inside and/or outside of, (c) inside of, or (d) interfacing with simulations. The first two of these views have been explored by David Chalmers and are used as jumping off points to introduce the latter two views, which are underdeveloped. If any one of these views could be proven (...) true, this would simultaneously both support a kind of account of properties of consciousness and also provide a kind of sign as to whether or not we are indeed living in a simulation. Given that none of these views are proven true but all are plausible, these considerations should tend to neutralize our credences that we are either simulated or not simulated, by themselves giving us no sign one way or the other.

While philosophers have worried about mental causation for centuries, worries about the causal relevance of conscious phenomena are also increasingly featuring in neuroscientific literature. Neuroscientists have regarded the threat of epiphenomenalism as interesting primarily because they have supposed that it entails free will scepticism. However, the steps that get us from a premise about the causal irrelevance of conscious phenomena to a conclusion about free will are not entirely clear. In fact, if we examine popular philosophical accounts of free will, (...) we find, for the most part, nothing to suggest that free will is inconsistent with the presence of unconscious neural precursors to choices. It is only if we adopt highly non-naturalistic assumptions about the mind (e.g. if we embrace Cartesian dualism and locate free choice in the non-physical realm) that it seems plausible to suppose that the neuroscientific data generates a threat to free will.

I argue that the present (if not insuperable) lack of fixed standards in philosophy is associated with three barriers to philosophical progress, pertaining to intra-disciplinary siloing, sociological rather than philosophical determinants of philosophical attention, and the encouraging of bias.

Thomas Reid’s philosophy is a philosophy of mind—a Pneumatology in the idiom of 18th century Scotland. His overarching philosophical project is to construct an account of the nature and operations of the human mind, focusing on the two-way correspondence, in perception and action, between the thinking principle within and the material world without. Like his contemporaries, Reid’s treatment of these topics aimed to incorporate the lessons of the scientific revolution. What sets Reid’s philosophy of mind apart is his commitment to (...) a set of intuitive contingent truths he called the principles of common sense. This difference, as this chapter will show, enables Reid to construct an account of mind that resists the temptation to which so many philosophers in his day and ours succumb, i.e., the temptation, in his words, to materialize minds or spiritualize bodies.

Laplacean Determinism (his so-called demon argument) is the thesis that every event that transpires in a closed universe is a physical event caused (i.e., determined) in full by some earlier event in accord with laws that govern their behavior. On this view, it is possible, in principle, to make perfect predictions of the state of the universe at any time Tn on the basis of complete knowledge of the state of the universe at time T1. Thus, if identity theory, epiphenomenalism (...) or any other instantiation of Laplacean Determinism is correct, mental events such as free will, intention and other forms of mental agency are tricks of the mind, misleading us into believing our volitional concerns have traction in a world ruled entirely by physical circumstance. Not surprisingly, advocates of free will and related acts of human volition have engaged in spirited debate with adherents to Laplacean orthodoxy, the results of which have been far from conclusive. Rather than join these deliberations, I wholly embrace the demon argument and then ask “what are the consequences of this allegiance?” As I hope to show, acceptance of this argument commits one to a belief in the existence of human precognition. This, I suggest, is a consequence that does not fit comfortably within a contemporary scientific worldview. (shrink)

There are many ways for truths to be true. How should we understand that idea? One is that there are different kinds of truth: the _ways_ are different truth-like properties. Another understanding is that a truth can be made true in different ways, by different kinds of entities. The former understanding supports alethic pluralism. But the latter can be understood as a kind of monism: truth is the existential property of having some truthmaker or other. On this view, the differences (...) reside in how a truth is made true, but not in its being true. I’ll discuss how these two understandings differ and what the potential advantages of the latter idea might be. (shrink)

Durante los siglos XVII y XVIII hubo un intenso debate en las Islas Británicas en torno al materialismo. Mi objetivo consiste en caracterizar la postura de David Hume en el marco de ese debate. Sostengo que, no obstante rechazar la metafísica sustancialista para centrarse en el estudio de las percepciones, Hume sienta una posición respecto de la relación entre mente y materia. Sin embargo, esa posición reviste cierta complejidad en tanto no es explicitada en los textos que se editaron en (...) vida de Hume. Propongo definirla como un materialismo restringido, ya que, respecto de la naturaleza de la mente, Hume desestima tanto las posturas materialista como inmaterialista, pero respecto de las causas del pensamiento, termina acercándose al materialismo a partir de argumentos basados en la experiencia y en la analogía con la naturaleza.

Can nonhuman animals and artificial intelligence (AI) entities be attributed moral agency? The general assumption in the philosophical literature is that moral agency applies exclusively to humans since they alone possess free will or capacities required for deliberate reflection. Consequently, only humans have been taken to be eligible for ascriptions of moral responsibility in terms of, for instance, blame or praise, moral criticism, or attributions of vice and virtue. Animals and machines may cause harm, but they cannot be appropriately ascribed (...) moral responsibility for their behavior. This thesis challenges the conventional paradigm by proposing an alternative approach where moral agency is conceived as the competence to participate in moral responsibility practices. By shifting focus from intra-individual to contextual and socially situated features, this practice-focused approach appears to make the attribution of moral agency to nonhuman animals and AI entities more plausible than commonly assumed. Moreover, considering the current and potential future prevalence of nonhuman animals and AI entities in everyday settings and social contexts, a potential extension of moral agency to such entities could very well transform our social, moral, and legal practices. Hence, this thesis proposes that the attribution or withholding of moral agency to different entities should be carefully evaluated, considering the potential normative implications. (shrink)

Esta enciclopédia abrange, de uma forma introdutória mas desejavelmente rigorosa, uma diversidade de conceitos, temas, problemas, argumentos e teorias localizados numa área relativamente recente de estudos, os quais tem sido habitual qualificar como «estudos lógico-filosóficos». De uma forma apropriadamente genérica, e apesar de o território teórico abrangido ser extenso e de contornos por vezes difusos, podemos dizer que na área se investiga um conjunto de questões fundamentais acerca da natureza da linguagem, da mente, da cognição e do raciocínio humanos, bem (...) como questões acerca das conexões destes com a realidade não mental e extralinguística. A razão daquela qualificação é a seguinte: por um lado, a investigação em questão é qualificada como filosófica em virtude do elevado grau de generalidade e abstracção das questões examinadas (entre outras coisas); por outro, a investigação é qualificada como lógica em virtude de ser uma investigação logicamente disciplinada, no sentido de nela se fazer um uso intenso de conceitos, técnicas e métodos provenientes da disciplina de lógica. O agregado de tópicos que constitui a área de estudos lógico-filosóficos é já visível, pelo menos em parte, no Tractatus Logico-Philosophicus de Ludwig Wittgenstein, uma obra publicada em 1921. E uma boa maneira de ter uma ideia sinóptica do território disciplinar abrangido por esta enciclopédia, ou pelo menos de uma porção substancial dele, é extrair do Tractatus uma lista dos tópicos mais salientes aí discutidos; a lista incluirá certamente tópicos do seguinte género, muitos dos quais se podem encontrar ao longo desta enciclopédia: factos e estados de coisas; objectos; representação; crenças e estados mentais; pensamentos; a proposição; nomes próprios; valores de verdade e bivalência; quantificação; funções de verdade; verdade lógica; identidade; tautologia; o raciocínio matemático; a natureza da inferência; o cepticismo e o solipsismo; a indução; as constantes lógicas; a negação; a forma lógica; as leis da ciência; o número.

Guthrie contends that religion can best be understood as systematic anthropomorphism - the attribution of human characteristics to nonhuman things and events. Religion, he says, consists of seeing the world as human like. He offers a fascinating array of examples to show how this strategy pervades secular life and how it characterizes religious experience.

Carey has argued that there is a system of core numerical cognition – the analog magnitude system – in which cardinal numbers are explicitly represented in iconic format. While the existence of this system is beyond doubt, this paper aims to show that its representations cannot have the combination of features attributed to them by Carey. According to the argument from abstractness, the representation of the cardinal number of a collection of individuals as such requires the representation of individuals as (...) such, and this in turn requires non-iconic format, from which it is concluded that the explicit representation of the cardinal number of some individuals requires non-iconic representational format. In support of the first premise, an account is given of what approximate cardinal numbers might be, and in support of the second, a direct argument is articulated and defended. Finally, in response to an objection, a second argument for the central thesis is provided. While the discussion is couched in the terms of Carey’s work, the considerations it adduces are perfectly general, and the conclusion should therefore be taken into consideration by all those aiming to characterize the AM system.

Emotion Review, Volume 14, Issue 1, Page 3-14, January 2022. Advocates for the psychological construction of emotion view themselves as articulating a non-essentialist alternative to basic emotion theory's essentialist notion of affect programs. Psychological constructionists have also argued that holding essentialist assumptions about emotions engenders misconceptions about the psychological constructionist viewpoint. If so, it is important to understand what psychological constructionists mean by “essentialism” and “non-essentialism.” To advance the debate, I take a deeper dive into non-essentialism, comparing the non-essentialist views (...) of the early empiricists with those of the psychological constructionists, focusing on the theories of James Russell and Lisa Barrett. Using Lakatos’ notion of scientific research programs, I also describe how Russell's and Barrett's views have evolved into different and potentially competing research programs under the psychological constructionist banner.

For a long time, under the influence of traditional Western philosophy, Orthodox interpreters have distorted Marx’s philosophy as the ontology of matter, thereby concealing the essence of Marx’s philosophy, and eliminating the fundamental difference between Marx’s philosophy and traditional philosophy. This paper proposes that Marx’s philosophy is not the ontology of matter, but on the contrary, by examining the ontology of matter, Marx put forward his own ontological theory, i.e., the ontology of the praxis-relations of social production, by which Marx (...) linked the realms of phenomenon and essence, revealing the content and essence of his philosophy.

Supporters of the A-theory of time sometimes refer to an alleged experience of the passage of time in support of their theory. In this paper I argue that it is an illusion that we experience the passage of time, for such an experience is impossible. My argument relies on the general assertion that experience is contingent, in the sense that if it is possible to experience the passage of time, it is also possible to experience that time does not pass. (...) Having established this claim, I argue that it is impossible to experience that time does not pass, and hence that it is impossible to experience the passage of time. (shrink)

The first half of this review article on Locke on primary and secondary qualities leads up to a fairly straightforward reading of what Locke says about the distinction in Essay II.viii, one that, in its general outlines, represents a sympathetic understanding of Locke’s discussion. The second half of the paper turns to consider a few of the ways in which interpreting Locke on primary and secondary qualities has proven more complicated. Here we take up what is sometimes called the Berkeleyan (...) interpretation of Locke, the understanding of Locke’s resemblance thesis, and Locke’s views of qualities and their relationship to powers.

This paper proposes an analysis of statements about universals according to which such statements assert nothing more than that the evidence we’d take to confirm them obtains, where this evidence is understood to consist solely of patterns in the behavior of particulars that cannot be explained by other regularities in the way things behave. On this analysis, to say that a universal exists is simply to say that there is such a pattern in the behavior of certain particulars, and for (...) any predicate F that is presumed to correspond to a universal, to say that a particular is F is simply to say that its behavior exhibits a pattern of this sort. I argue that there is no theoretical work that we want postulations and ascriptions of universals to do that they’d be unfit for if analyzed in this way, and consequently that there is no reason to treat such statements as asserting anything more than what the proposed analysis suggests.

Hume sought to analyse our propositionally-structured thought in terms of our ultimate awareness of nothing but objects, sensory impressions or their imagistic copies, The ideas of space and time are often regarded as exceptions to his Copy Theory of impressions and ideas. On grounds strictly internal to Humes account of the generality of thought. This ultimately reveals the limits of the Copy Theory and of Concept Empiricism. The key is to recognise how very capacious is our (Humean) imaginative capacity to (...) associate particular perceptions by various fine-grained determinable resemblances. (shrink)

Theories concerning the structure, or format, of mental representation should (1) be formulated in mechanistic, rather than metaphorical terms; (2) do justice to several philosophical intuitions about mental representation; and (3) explain the human capacity to predict the consequences of worldly alterations (i.e., to think before we act). The hypothesis that thinking involves the application of syntax-sensitive inference rules to syntactically structured mental representations has been said to satisfy all three conditions. An alternative hypothesis is that thinking requires the construction (...) and manipulation of the cognitive equivalent of scale models. A reading of this hypothesis is provided that satisfies condition (1) and which, even though it may not fully satisfy condition (2), turns out (in light of the frame problem) to be the only known way to satisfy condition (3).

The authors favor a “color realism” theory that considers colors to be physical properties residing in objects that reflect, emit, or transmit light. It is opposed to the theory that colors are sensations or visual experiences. This commentary suggests that both theories are correct, and that context usually indicates which of these dual aspects is being considered.

_ Source: _Page Count 29 Underdetermination arguments for skepticism maintain that our common sense view of the external world is no better, evidentially speaking, than some skeptical competitors. An important and well-known response by dogmatists, those who believe our commonsense view is justified, appeals to abduction or inference to the best explanation. The predominant version of this strategy, going back at least to Locke, invokes Occam’s razor: dogmatists claim the common sense view is simpler than any of its skeptical alternatives (...) and so has more to recommend it, evidentially speaking. This dispute has overshadowed another possible view: skeptical dogmatism. Skeptical dogmatists hold that we are justified in believing that the common sense view is probably false. I argue that skeptical dogmatism presents some interesting complications to the dialectic between the dogmatist and the skeptic. On the one hand, even if the dogmatist’s use of Occam’s razor is sufficient to rebut skepticism, in itself it is not sufficient to refute skeptical dogmatism. On the other hand, skeptics themselves, ironically, must, given the assumptions of the paper, appeal to something like Occam’s razor in order to avoid capitulating to skeptical dogmatism. (shrink)

I argue that if we allow that Moore’s Method, which involves taking an ordinary knowledge claim to support a substantive metaphysical conclusion, can be used to support Moore’s proof an external world, then we should accept that Moore’s Method can be used to support a variety of incompatible metaphysical conclusions. I shall refer to this as “the problem of many proofs”. The problem of many proofs, I claim, stems from the theory-ladenness of perception. I shall argue further that this plethora (...) of proofs for incompatible positions leads to a darker form of skepticism, one which maintains that each of the dogmatic views is probably false. We will conclude by considering various ways a Moorean might respond to these difficulties. (shrink)

The reflectance types that Byrne & Hilbert identify with colors count as types only in a way that is more dependent on, and more relative to color perceivers, than their account suggests. Their account of perceptual content may be overly focused on input conditions and distal causes.

Cognitive sciences have been interminably in search for a consistent philosophical framework for the description of perceptual phenomena. Most of the frameworks in usage today fall in-between the extremes of constructivism and objective realism. However, whereas constructivist cognitive theories face difficulties when attempting to explain the experiential commonality of different cognitive entities, objectivistic theories fail in explaining the active role of the subject in the formation of experiences. This paper undertakes to compare and eventually combine these two major approaches to (...) describing cognitive phenomena. It is argued that constructivist explanations inevitably refer to a `hidden' ontological source of experience, and that a compromise between the constructivist and realistic standpoints presents a natural basis for understanding cognitive phenomena. A view of all experiences as co-created through an interplay between a constructivist creativity and a realistic source of perceptual stimuli is proposed. A middle ground between the hardly compatible constructivist and objectivistic approaches to experiential realities is proposed from the standpoint of experiential co-creation. Traditionally divided, idealistic and realistic philosophical stances may thus become merged into a single consistent epistemological framework. Many favorable cognitive and psychosomatic consequences may arise from acknowledging the balance between `inner' and `outer' creativity proposed by the co-creational thesis. (shrink)

Radical skepticism is the view that we know nothing, or at least next to nothing. Nearly no one actually believes that skepticism is true. Yet it has remained a serious topic of discussion for millennia and it looms large in popular culture. What explains its persistent and widespread appeal? How does the skeptic get us to doubt what we ordinarily take ourselves to know?

First, people evaluate inferential belief more harshly than perceptual belief. Second, people evaluate inferential belief more harshly when its content is negative (i.e. that something is not the case) than when it’s positive (i.e. that something is the case). It just so happens that potent skeptical arguments tend to focus our attention on negative inferential beliefs, and we are especially prone to doubt that such beliefs count as knowledge. That is, our cognitive evaluations are biased against this specific combination of source and content. The skeptic sows seeds of doubt by exploiting this feature of our psychology. (shrink)

Centuries ago, Descartes and Locke initiated a foundational debate in epistemology over the relationship between knowledge, on the one hand, and practical factors, on the other. Descartes claimed that knowledge and practice are fundamentally separate. Locke claimed that knowledge and practice are fundamentally united. After a period of dormancy, their disagreement has reignited on the contemporary scene. Latter-day Lockeans claim that knowledge itself is essentially connected to, and perhaps even constituted by, practical factors such as how much is at stake, (...) how important the situation is, or how one should act. Latter-day Cartesians claim, by contrast, that knowledge is entirely constituted by truth-related factors such as truth, belief, and evidence. Each side has supported its case with claims about patterns in ordinary behavior and knowledge judgments. Lockeans argue that these patterns are best explained by positing a fundamental and direct link between knowledge and practical factors. Cartesians argue that the patterns can be equally well explained by positing an indirect link, entirely mediated by the traditional factors of truth, belief, and evidence, thereby rendering the Lockean hypothesis unnecessary. We argue that Cartesians are right about some practical factors, in particular stakes and how important a situation is, which have, at best, a modest indirect relationship to knowledge. However, Lockeans are right about actionability: whether a person should pursue a course of action is unquestionably very powerfully and directly connected to knowledge. (shrink)

Philosophy Compass, Volume 17, Issue 7, July 2022.

The aim of this paper is to offer a general survey of the latest development of metaphysical idealism in contemporary Anglo-American philosophy. It consists of five main parts. The first part is a short introduction, it states the position of idealism and its current status in the Anglophone world. The second part focuses on the negative programme of idealism, which challenges physicalism on the problem of matter (2.1) and the problem of consciousness (2.2). The third part illustrates the positive programme (...) of idealism, whose varieties can be grouped into two principal types: constitutive and elementary. Constitutive idealism (3.1) is subdivided into the theocentric (3.1.1), the anthropocentric (3.1.2), and the acentric (3.1.3). Elementary idealism (3.2), on the other hand, can be unity-based (3.2.1), language-based (3.2.2), or knowledge-based (3.2.3). The six categories form a general framework of metaphysical idealism, and various accounts in the existing literature are discussed under each category. The fourth part addresses the relation between idealism and panpsychism. The paper is concluded with some caveats and future prospects. (shrink)

In the Essay Locke argues abstract ideas within the framework of the descriptivist theory of reference. For him, abstract ideas are, in many cases, conceptual ideas that play the role of “descriptions” or “descriptive contents,” determining general terms’ referents. In contrast, in the introduction of the Principles, Berkeley denies Lockean abstract ideas adamantly from an imagistic point of view, and he offers his own theory of reference seemingly consisting of referring expressions and their referents alone. However, interestingly, he mentions a (...) general term’s “definition” and suggests that it determines the scope of the term’s referents. For example, he takes up the definition of a triangle as “a plain Surface comprehended by three right Lines” and suggests that just as Locke’s general idea of a triangle does, the definition determines the referents of the general term “triangle.” His definition reminds us of the fact that as Descartes grasps the content of the general idea of a triangle as “a figure enclosed by three lines,” so Locke grasps the abstract idea of a triangle as “a Figure including a Space between three Lines,” and so on. That is, since Berkeley is an imagist, he does not acknowledge Locke’s conceptual abstract ideas as “ideas,” but although he verbally denies “abstract ideas,” his theory of reference also actually has the same descriptivist framework consisting of referring expressions, their descriptive contents, and their referents. Thus, we understand the real reason why Berkeley’s criticism of Locke seems beside the point. (shrink)
