Berkeley: Skepticism

This paper argues for a re-evaluation of the relationship between Berkeley and his predecessor, the neo-Aristotelian thinker John Sergeant. In the literature to date, the relationship between these two thinkers has received attention for two reasons. First, because some commentators have attempted to establish a causal connection between them – specifically, by focusing on the fact that both thinkers develop a theory of ‘notions’. Second, because both Berkeley and Sergeant develop ‘anti-representationalist’ arguments against Locke’s epistemology. The first issue has received (...) much greater attention, particularly from commentators seeking an explanation for Berkeley’s use of the term ‘notion’. Only one scholar, G. A. Johnston (in 1923), has considered Berkeley and Sergeant’s anti-representationalism in any depth. In this paper, I argue that the weight given to the causal connection between Berkeley and Sergeant’s ‘notions’ is misplaced since the evidence in favour of this connection is weaker than is usually acknowledged. Instead, I build on Johnston’s analysis of the conceptual connection between Berkeley and Sergeant’s anti-representationalism. I first corroborate Johnston’s claim that there are striking similarities between their criticisms of Locke before going beyond that analysis by identifying two important similarities between their anti-representationalist arguments.

It is argued that George Berkeley’s term ‘common sense’ does not indicate shared conviction, but the shared capacity of reasonable judgement, and is therefore to be classed as a mental ability, not a belief-system. Common sense is to be distinguished from theoretical understanding which, in Berkeley’s view, is frequently corrupted either by learned prejudice, or by language that lacks meaning or camouflages contradiction. It is also to be distinguished from the deliverances of divine revelation, which—however enlightening Berkeley supposed them to (...) be—are not necessarily available to all people. This interpretation of common sense is supported both by attention to Berkeley’s own texts, including his sermons, letters and philosophical writings, and by attention to the views of John Locke and René Descartes, who also understand ‘common sense’ as susceptibility to the ‘natural light’. In addition, this interpretation renders Berkeley’s appeal to common sense in support of his immaterialism a straightforward appeal to the reader’s native reason. No longer, then, are we forced to see Berkeley as improbably maintaining that the denial of matter is really the view of ‘the common people’, but rather that those who have least attachment to theory and doctrine will be best able to grasp the case for immaterialism.

Readers and historians have often misunderstood Berkeley's philosophy by believing that he denies the existence of the external world. From which they conclude that his philosophy inevitably leads to solipsism. Faced with these readings, in this paper I discuss the relationship between ontology and the external world in Berkeley with the aim of clarifying some interpretative errors and showing three things: 1) that is a mistake to believe Berkeley’s philosophy eliminate the external world and lead to solipsism, 2) that his (...) own ontology is the key to understand the constitution of the external world, and 3) that God gives the ultimate meaning of that world. / Es habitual que algunos lectores confundan la postura de Berkeley al creer que niega la existencia del mundo externo y que su filosofía lleva inevitablemente al solipsismo. Frente a estas lecturas, analizo en este artículo el tema de la relación entre ontología y mundo externo en Berkeley, con el propósito de aclarar algunos desaciertos interpretativos sobre el asunto y mostrar con ello tres cosas: 1) que se trata de un error creer que su filosofía elimina el mundo externo y lleva al solipsismo, 2) que en la propia ontología está la clave para entender la constitución del mundo externo, y 3) que Dios le da el sentido último a ese mundo.

In this paper, I argue that dreaming arguments are no cause for alarm.

Both Reid and Berkeley reject ‘representationalism’, an epistemological position whereby we perceive things in the world indirectly via ideas in our mind, on the grounds of anti-scepticism and common sense. My aim in this paper is to draw out the similarities between Reid and Berkeley's ‘anti-representationalist’ arguments, whilst also identifying the root of their disagreements on certain fundamental metaphysical issues. Reid famously rejects Berkeley's idealism, in which all that exists are ideas and minds, because it undermines the dictates of common (...) sense. Reid also charges Berkeley with not only accepting but furthering the progress of ‘the Way of Ideas’, a longstanding tradition which has drawn philosophy away from true science and common sense. From Berkeley's perspective, Reid is a ‘materialist’; that is, he dogmatically accepts that mind-independent things exist. I argue that these important differences can be explained by both thinkers’ construal of certain ‘philosophical prejudices’. Finally, I conclude that despite these differences, both ought to be characterised as ‘anti-representationalists’ in light of their shared epistemological concerns. (shrink)

George Berkeley (1685-1753) is one of the most influential early modern philosophers, and in reason of this a never-ending critical interest focuses on his works. Such a critical attention gave rise to a broad literature and it is in fact quite easy to find valuable introductory books to Berkeley's works. It would be thus superfluous to provide a further summary of the entire production of Berkeley. Rather, I focus on a specific issue, namely the main points of interest of immaterialism (...) for the contemporary debates in philosophy. The currently most discussed Berkeleian arguments are those from his earlier production (those developed around 1709-1713). Thus, I will be mainly concerned with the conceptual structure of A Treatise Concerning the Principles of Human Knowledge. Among Berkeley's early works, this is the one that was thought as a systematic illustration for philosophers of his ideas. (shrink)

Berkeley's immaterialism aims to undermine Descartes's skeptical arguments by denying that the connection between sensory perception and reality is contingent. However, this seems to undermine Berkeley's (alleged) defense of commonsense by failing to recognize the existence of objects not presently perceived by humans. I argue that this problem can be solved by means of two neglected Berkeleian doctrines: the status of the world as "a most coherent, instructive, and entertaining Discourse" which is 'spoken' by God (Siris, sect. 254) and the (...) nature of language as a public social practice. Together these doctrines entail that ordinary physical objects, including those that are not presently perceived, are a joint product of divine discursive activity and human interpretive activity.

The defense of common sense in Berkeley's Three Dialogues is, first and foremost, a defense of the gardener's claim to know this cherry tree, a claim threatened by both Cartesian and Lockean philosophy. Berkeley's defense of the gardener's knowledge depends on his claim that the being of a cherry tree consists in its being perceived. This is not something the gardener believes; rather, it is a philosophical analysis of the rules unreflectively followed by the gardener in his use of the (...) word 'exists'. It is by following these rules that the gardener gains knowledge of the cherry tree. Uncovering these deep connections between Berkeley's epistemology and his philosophy of language and placing them in the context of his critique of both Cartesian and Lockean philosophy will clarify Berkeley's strategy for bringing his reader back to common sense and practical engagement in the ordinary affairs of life.

Anthony Brueckner argues that Berkeleyan idealism lacks anti-sceptical force because of the way Berkeley draws the appearance/reality distinction. But Brueckner's case rests on a misunderstanding of Berkeley's view. Properly understood, Berkeleyan idealism does indeed have anti-sceptical force.

Nearly as famous as his denial of the existence of matter is Berkeley's insistence that his philosophy is somehow a defense of commonsense. This is most often taken to mean that Berkeley thinks of his philosophy as supporting commonsense beliefs. However, the inadequacies of such views have persuaded some to disregard entirely Berkeley's claims about commonsense. Both readings are undesirable. Extant interpretations misunderstand the relationship between Berkeley's philosophy and commonsense. In this paper, I present a new account of how to (...) understand Berkeley's so-called defense of commonsense; it is not a defense-cum­-apology for commonsense beliefs, but a defensive attack against a skeptical threat. I then examine two rival accounts of the defense of commonsense and show how each fails to satisfy the criteria for a successful account. Finally, I briefly address the implications this view has for future scholarship. (shrink)

It is argued that contrary to appearances, Berkeleyan Idealism lacks anti-sceptical force. The problem stems from the way in which the idealist draws the appearance/reality distinction.

In this paper, I survey the way Wittgenstein reacts to radical philosophical doubt in his On Certainty.He deems skeptical doubt in some important cases idle, pointless or otherwise negligible. I point out that several passages of On Certainty make it difficult to judge whether Wittgenstein intends to address a skeptic or a metaphysical idealist. Drawing attention to the anti-skeptical nature of Berkeley’s idealism, I go on to argue that the question is far from trivial: rather, it affects the way we (...) should evaluate Wittgenstein’s arguments in On Certainty in general. I finally attempt to explain why Wittgenstein remained ambiguous about the target of his arguments, and discuss the possibility of making room for the idealism/skepticism distinction in On Certainty’s framework.

One of Berkeley’s main goals in the Principles and in the Three Dialogues, as expressly stated in the full titles these two works, as well as in the Philosophical Commen-taries, is the refutation of skepticism. This article aims to elucidate what Berkeley means by skepticism and to indicate which principles or doctrines, according to him, are at the root of the skeptics’ doubts. An attempt is made to show how Berkeley elaborated his opposition to skepticism. Finally, it is suggested that (...) Berkeley’s (alleged) refutation of the skepticism, given his doctrine of immaterialism, is not based only on the esse est percipi principle, but also on the thesis that the objects and their sensible qualities are immedi-ately perceived. It is pointed out that, in Berkeley’s view, this thesis is compatible with common sense, what makes it plausible to consider his theory of perception as a form of direct realism. (shrink)

Um dos principais objetivos de Berkeley nos Princípios e nos Três Diálogos, como expressamente enunciado nos títulos completos dessas duas obras e nos cadernos de anotações que antecipam sua elaboração, é a refutação do ceticismo. Este artigo procura explicitar o que Berkeley entende por ceticismo e indicar quais os princípios ou doutrinas que, segundo ele, suscitam as dúvidas dos céticos. Em seguida, procura mostrar como se dá a oposição de Berkeley ao ceticismo. No final, sugere que a refutação do ceticismo (...) por parte de Berkeley, dada a doutrina que ele mesmo denomina de imaterialismo, não se baseia apenas na defesa do princípio esse est percipi, mas é complementada pela tese de que os objetos e suas qualidades sensíveis são imediatamente percebidos. Uma tese que, na concepção de Berkeley, é compatível com a visão do senso comum, o que sugere que ele talvez pudesse considerar a sua teoria da percepção como uma forma de realismo direto. (shrink)

Berkeley claims idealism provides a novel argument for the existence of God. But familiar interpretations of his argument fail to support the conclusion that there is a single omnipotent spirit. A satisfying reconstruction should explain the way Berkeley moves between first person singular and plural, as well as providing a powerful argument, once idealism is accepted. The new interpretation offered here represents the argument as an inference to the best explanation of a shared reality. Consequently, his use of the first (...) person must be taken as ‘exemplary’ rather than ‘Cartesian’. This explains the freedom of movement in the text between singular and plural. However, it also reveals Berkeley as side-stepping sceptical doubt. (shrink)

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

Ted Honderich's 'Radical Externalism' concerning the nature of consciousness is a refreshing, and in many ways very appealing, approach to a long- standing and seemingly intractable philosophical conundrum. Although I sympathize with many of his motivations in advancing the theory and share his hostility for certain alternative approaches that are currently popular, I will serve him better by playing devil's advocate than by simply recording my points of agreement with him. If his theory is a good one, it should be (...) able to stand up to the strongest criticisms that we can muster against it. I shall do my best to articulate some of those criticisms as forcefully as I can. (shrink)

O artigo compara alguns aspectos da refutação do ceticismo nos Princípios e nos Três diálogos. Embora normalmente não se veja nenhuma diferença importante entre essas obras, duas hipóteses são defendidas aqui: de um lado, Berkeley desloca o foco de sua crítica das idéias abstratas para a noção de matéria e, de outro, muda sua estratégia de combate, da enunciação imediata da verdade para a lenta elaboração das consequências céticas da noção de matéria. Berkeley’s answers to skepticismThe topic of this paper (...) is a comparison between Berkeley´s refutation of skepticism in the Principles and in the Three Dialogues. It is usually held that there is no philosophical difference between these two works. However, I suggest that not only Berkeley´s diagnosis of the causes of skepticism changes from his criticism of abstract ideas to the notion of matter, but also that he changes his strategy of refutation: from a direct statement of the truth of immaterialism to an examination of the consequences of the notion of matter.

resumo A influência do ceticismo nos século XVI e XVII é por demais evidente para ser posta em questão. De Montaigne a Bayle, parece que o cético foi o promotor tanto de uma refutação radical dos princípios metafísicos escolásticos e depois cartesianos quanto de uma crítica feroz às autoridades religiosas e políticas. Ora, esse papel parece ter se amenizado no Século das Luzes, ou melhor, se deslocado - somente as dimensões críticas do social continuaram pertinentes. Pretende-se mostrar aqui o pressuposto (...) de uma tal leitura que leva em conta apenas o aspecto visível da crítica cética e mostrar que o ceticismo, sob uma forma particular, foi uma das grandes questões da epistemologia das Luzes e que ele é indissociável, para ser compreendido em toda a sua dimensão polêmica, da recepção européia do imaterialismo berkeleyano. O objetivo de nossa intervenção se faz compreender então claramente: explicar primeiramente como uma tal concepção epistemológica pôde nascer em terra cartesiana e quais foram os seus líderes desse solipsismo das Luzes, a supor que os tenha havido, para mostrar, em seguida, porque ela pôde se tornar uma questão metafísica maior no século XVIII, antes de definir, para concluir, os interesses a que ela serviu ou desserviu. palavras-chave cartesianismo – imaterialismo – Luzes – materialismo – metafísica – ceticismo - solipsismo.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Berkeley au siècle des Lumières: Immatérialisme et scepticisme au XVIIIe siècleTodd RyanSébastien Charles. Berkeley au siècle des Lumières: Immatérialisme et scepticisme au XVIIIe siècle. Preface by Geneviève Brykman. Paris: Vrin, 2003. Pp. 368. Paper, € 28,00.The reception accorded to Berkeley's immaterialism by eighteenth-century philosophers constitutes one of the great puzzles of early modern philosophy. How is it possible that Berkeley, whose announced purpose in both the Principles and (...) Three Dialogues was to refute "Skeptics and Atheists," should quickly come to be seen as the foremost champion of Pyrrhonian skepticism, and indeed of atheistic solipsism? To be sure the caricature of philosophical opponents for polemical purposes is hardly limited to Berkeley. Yet from the [End Page 495] modern point of view Berkeley, the "good Bishop" who tirelessly insisted on the consonance of immaterialism with common sense, as well as the indispensable role of God as cause of our ideas of sense, seems a rather unlikely candidate for the near universal hostility—one might even say vilification—that was to be his lot.Forty years ago Harry M. Bracken attempted to unravel this paradox in his classic study The Early Reception of Berkeley's Immaterialism. Through a careful and philosophically informed examination of early accounts of Berkeley's immaterialism, Bracken argued that the distorted image of Berkeley that was to become the common currency of Enlightenment thinkers had its origin in the earliest accounts of Berkeley's work, most notably a pair of reviews in the Jesuit journal Mémoires de Trévoux, and a vituperative attack on "the atheism of the Immaterialists" by Father Tournemine. According to Bracken, the image of Berkeley as a radical disciple of Malebranche who pushed the Oratorian's philosophy to its logical conclusion by denying the existence of matter was promoted by the Jesuits as part of their theological and political struggle against Cartesianism. It was also in these early reviews that Berkeley's name was first associated with the legendary "egoist" philosopher who in addition to denying the existence of material substance, further claimed that his was the only created spirit in existence.Sébastien Charles's impressive new study extends Bracken's work by carefully documenting the dissemination of this distorted image of Berkeley throughout the intellectual world of eighteenth-century Europe. Charles's book is a comprehensive and impressively erudite survey of the use (and misuse) of Berkeley in the writings of the philosophes, as well as later thinkers, including the Idéologues and members of the Berlin Academy. Sadly, though perhaps not unexpectedly, the texts that Charles surveys afford little critical insight to interpreters of Berkeley. The misreadings of Berkeley are so egregious and so pervasive that the philosophy of the Principles and Three Dialogues is generally disfigured beyond recognition. Indeed, even to speak of a "misreading" of Berkeley is somewhat misleading, since many of those who took up the task of refuting immaterialism seem not to have read him at all.However, Charles's aim is much less to shed interpretive light on Berkeley's philosophy than to rectify the long-standing image of the eighteenth century as an era of unbridled epistemological optimism. Emphasizing the confrontations with radical skepticism to be found in the writings of thinkers as diverse as Rousseau and Diderot, La Mettrie and Destutt de Tracy, Charles argues that far from ignoring the threat of radical skepticism, materialists and dualists, deists and Christians made common cause in their struggle against what they took to be Berkeley's alleged "egoism." Indeed, for Charles, "the question of solipsism was the central problem for the metaphysics of the Enlightenment."The ubiquity of references to Berkeley among these thinkers certainly argues in favor of Charles's thesis. Yet the attempt to survey such a large number of authors frequently necessitates an abbreviated treatment that renders difficult the task of assessing the relative importance of the confrontation with radical skepticism in any individual thinker's system. Further, the very weakness and formulaic character of the attempted refutations might reasonably raise suspicions as to whether the threat of solipsism was taken as seriously as Charles maintains...

This essay reinterprets Berkeley’s idealism as partially motivated by a need to overcome the Agrippan mode of relativity pressed by Pyrrhonists. It compares Berkeley’s solution to that of Protagoras as presented in Plato’s Theaetetus, and argues that Berkeley needed to depend on reason — intuition or demonstration — to avoid skepticism. In this interpretation, Berkeley is closer to the rationalist tradition than usually recognized.

By his own account, Pappas "focuses on three core elements" of Berkeley's thought: abstraction, immediate perception, and common sense. The reader will also find interesting commentary on numerous other aspects of Berkeley's thought, including detailed treatments of the esse is percipi principle and Berkeley's claimed avoidance of skepticism.

In both the Principles and the Three Dialogues, Berkeley claims that he wants to uncover those principles which lead to scepticism; to refute those principles; and to refute scepticism itself. This paper examines the principles Berkeley says have scepticial consequences, and contends that only one of them implies scepticism.

Significant attention has been paid to Berkeley's account of perception; however, the interpretations of Berkeley's account of perception by suggestion are either incomplete or mistaken. In this paper I begin by examining a common interpretation of suggestion, the 'Propositional Account'. I argue that the Propositional Account is inadequate and defend an alternative, non-propositional, account. I then address George Pitcher's objection that Berkeley's view of sense perception forces him to adopt a 'non-conciliatory' attitude towards common sense. I argue that Pitcher's charge (...) is no longer plausible once we recognize that Berkeley endorses the non-propositional sense of mediate perception. I close by urging that the non-propositional interpretation of Berkeley's account of mediate perception affords a greater appreciation of Berkeley's attempt to bring a philosophical account of sense perception in line with some key principles of common sense. While Berkeley's account of perception and physical objects permits physical objects to be immediately perceived by some of the senses, they are, most often, mediately perceived. But for Berkeley this is not a challenge to common sense since common sense requires only that we perceive objects by our senses and that they are, more or less, as we perceive them. Mediate perception by suggestion is, for Berkeley, as genuine a form of perception as immediate perception, and both are compatible with Berkeley's understanding of the demands of common sense.

Dans la première méditation, Descartes a conclu, en regard des songes, « qu'il n'y a point d'indices concluants, ni de marques assez certaines par où l'on puisse distinguer nettement la veille d'avec la sommeil [...] » .

Cottingham a proposé une objection générale contre (...) tels indices de la veille: On peut rêver cet indice. Selon les raisonnements de Cottingham, il s'agit de l'existence de l'indice. Or, chez Leibniz et Descartes il ne s'agit pas de cela, mais il est question de savoir si l'indice est vraiment un indice de la veille. La prétention que l'indice puisse être présent en songe fait une pétition de principe. Notre examen des indices que Leibniz et Berkeley ont proposés révèle cette pétition. (shrink)

This paper analyzes berkeley's philosophy in the light of modern epistemology and philosophy of mind. It is shown that our knowledge of spatio-Temporal bodies cannot be certain. Certainty is restricted to the realm of sensory ideas themselves. But there is hardly any reason to be interested in ideas as such. Berkeley is a common sense thinker who wants to know the world and its scientific laws. Bodies are constructed on the basis of both real and imaginary ideas. This topic is (...) analyzed starting from pappas's and pitcher's views. It is shown that bodies are complete complexes of ideas and that imagination plays an essential role here. The continuity of bodies is discussed. The methods of making a distinction between real and imaginary ideas are analyzed. Concerning berkeley's philosophy of mind--It is shown that one can reach absolute certainty in this field but one cannot find much information concerning the various parts and functions of the mind. The difference between the active and the passive mind is discussed. The relations between ideas and the mind is explored briefly. (shrink)

In both the Principles and the Dialogues Berkeley argues that physical objects cannot exist independently of minds. In this paper I suggest an interpretation of the argument in the Dialogues that shows that his argument either relies on an invalid inference or begs the question. I conclude that his attempt to defeat scepticism by making physical objects mind-dependent is unsuccessful.

It is a standing temptation for philosophers to find anticipations of their own views in the great thinkers of the past, but few have been so bold in the search for precursors, and so utterly mistaken, as Berkeley when he claimed Plato and Aristotle as allies to his immaterialist idealism. InSiris: A Chain of Philosophical Reflexions and Inquiries Concerning the Virtues of Tar-Water, which Berkeley published in his old age in 1744, he reviews the leading philosophies of antiquity and finds (...) them on the whole a good deal more sympathetic to his own ideas than the ‘modern atheism’, as he calls it, of Hobbes and Spinoza or the objectionable principles of ‘the mechanic and geometrical philosophers’ such as Newton. But his strongest and, I think, his most interesting claim is that neither Plato nor Aristotle admitted ‘an absolute actual existence of sensible or corporeal things’. (shrink)

1. Introduction. Can Berkeleian idealism draw any support from the following argument?

There is a structural similarity between an influential argument of Berkeley 's against causal realism and a traditional, and recently revived, argument against the correspondence theory of truth. Both arguments chide the realist for positing a relation between his conceptions of reality and a world independent of those conceptions. Man could have no epistemic access to such a relation, it is said, for, by the realist's own admission, he has access to only one of the relata - his conceptions. I (...) claim that the relation in question need be no more than that alleged by the biological and behavioral sciences to hold between organisms and their environments. And when studied as such, it reveals ways whereby the realist may claim to know of an outward correspondence solely on the basis of characteristics of one of the relata - his conceptions. (shrink)

That the legacy of Berkeley's philosophy has been a largely sceptical one is perhaps rather surprising. For he himself took it as one of his objectives to undermine scepticism. He roundly denied that there were ‘any principles more opposite to Scepticism than those we have laid down’ . Yet Hume was to write of Berkeley that ‘most of the writings of that very ingenious author form the best lessons of scepticism, Bayle not excepted’. And it has become something of a (...) commonplace to say that Berkeley's philosophy is sceptical in direction, if not in intention. He is represented as a half-hearted sceptic, applying radical empiricist principles in his treatment of matter but baulking at their implications when he came to consider spirits. Hume is credited with being the more thoroughgoing of the two. Berkeley had denied the substantiality of extended things. Hume felt obliged, by parity of reasoning, to deny the substantiality of the self. On his account of the mind there is ‘properly no simplicity in it at one time, nor identity in different’ . It is commonly supposed that Berkeley, in maintaining the quite contrary view that we know ourselves to be simple, undivided beings , showed a lack of rigour or consistency. (shrink)
