In the Introduction to the Treatise concerning the Principles of Human Knowledge, Berkeley attacks the “received opinion that language has no other end but the communicating our ideas, and that every significant name stands for an idea” (PHK, Intro §19). How far does Berkeley go in rejecting this ‘received opinion’? Does he offer a general theory of language to replace it? If so, what is the nature of this theory? In this chapter, I consider three main interpretations of Berkeley's view: (...) the modified ideational theory, the speaker intentions theory, and the use theory. I argue that the use theory does, and its competitors do not, make sense of Berkeley's remarks on language in both the earlier and later works. (shrink)

In the Preface to the Three Dialogues<, Berkeley says that one of his main aims is to refute the free-thinkers. Puzzlingly, however, we are then treated to a dialogue between two Christians in which the free-thinkers never reappear. This is related to a second, more general puzzle about Berkeley's religious polemics: although Berkeley says he is defending orthodox conclusions, he also reminds himself in his notebooks "To use the utmost Caution not to give the least Handle of offence to the (...) Church or Church-men." What is Berkeley worried about? Both of these puzzles are solved by the recognition that the argument against matter in the Three Dialogues is patterned after an argument for atheism that Berkeley attributed to Anthony Collins. Berkeley's aim is thus to use the free-thinkers' own premises and arguments against them. In doing this, however, he rejects doctrines many churchmen held dear -- most notably, the doctrine of divine analogy. (shrink)

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.

To the great puzzlement of his readers, Berkeley begins by arguing that nothing exists other than minds and ideas, but concludes by claiming to have defended the existence of bodies. How can Berkeley's idealism amount to such a defense? I introduce resources from Berkeley's philosophy of language, and especially his analysis of the discourse of physics, to defend a novel answer to this question. According to Berkeley, the technical terms of physics are meaningful despite failing to designate any reality; their (...) meaningfulness derives from the useful role they play in organizing and predicting our experience. I argue that Berkeleian bodies have the same status as these theoretical entities: they are mere 'quasi-entities' introduced by our ways of speaking and thinking in order to serve our practical purposes. Berkeley nevertheless considers this to be a defense of the existence of bodies because he endorses a radically deflationary semantics for 'exists.'. (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.

Traditionally, religious doctrines and practices have been divided into two categories. Those that purport to be justified by natural reason alone are said to be part of natural religion, while those which purport to be justified only by appeal to supernatural revelation are said to be part of revealed religion. One of the central aims of Berkeley's philosophy is to understand and defend both the doctrines and the practices of both natural and revealed (Christian) religion. This chapter will provide a (...) survey of this aspect of Berkeley's thought. (shrink)

A plausible reading of Berkeley’s view of voluntary motion is occasionalism; this, however, leads to a specious conclusion against his argument of human action. Differing from an unqualified occasionalist reading, I consider the alternative reading that Berkeley is a conservationist regarding bodily motion by the human mind at will. That is, finite minds (spirits) immediately cause motions in their body parts, albeit under the divine conservation. My argument then comports with the conservationist reading from three perspectives: (i) theodicy that the (...) human mind is held liable for sinful actions; (ii) an account of the human mind influencing other minds; and (iii) an improper but necessary directing principle of the human mind. This article is a stepping stone to grasping why the conservationist reading is more coherent than the occasionalist one. (shrink)

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.

We argue that prevailing definitions of Berkeley’s idealism fail to rule out a nearby Spinozist rival view that we call ‘mind-body identity panpsychism.’ Since Berkeley certainly does not agree with Spinoza on this issue, we call for more care in defining Berkeley’s view. After we propose our own definition of Berkeley’s idealism, we survey two Berkeleyan strategies to block the mind-body identity panpsychist and establish his idealism. We argue that Berkeley should follow Leibniz and further develop his account of the (...) mind’s unity. Unity—not activity—is the best way for Berkeley to establish his view at the expense of his panpsychist competitors. (shrink)

This paper discerns two types of mathematization, a foundational and an explorative one. The foundational perspective is well-established, but we argue that the explorative type is essential when approaching the problem of applicability and how it influences our conception of mathematics. The first part of the paper argues that a philosophical transformation made explorative mathematization possible. This transformation took place in early modernity when sense acquired partial independence from reference. The second part of the paper discusses a series of examples (...) from the history of mathematics that highlight the complementary nature of the foundational and exploratory types of mathematization.

George Berkeley, Bishop of Cloyne, was one of the great philosophers of the early modern period. He was a brilliant critic of his predecessors, particularly Descartes, Malebranche, and Locke. He was a talented metaphysician famous for defending idealism, that is, the view that reality consists exclusively of minds and their ideas. Berkeley's system, while it strikes many as counter intuitive, is strong and flexible enough to counter most objections. His most studied works, the Treatise Concerning the Principles of Human Knowledge (...) Principles, for short) and Three Dialogues between Hylas and Philonous Dialogues), are beautifully written and dense with the sort of arguments that delight contemporary philosophers. He was also a wide ranging thinker with interests in religion (which were fundamental to his philosophical motivations), the psychology of vision, mathematics, physics, morals, economics, and medicine. Although many of Berkeley's first readers greeted him with incomprehension, he influenced both Hume and Kant, and is much read (if little followed) in our own day. (shrink)

Berkeleyan idealism, or ‘immaterialism,’ has had an enormous impact on the history of philosophy during the last three centuries. In recent years, Christian scholars have been especially active in exploring ways that Berkeley's thesis may be fruitfully applied to a variety of issues in philosophy and theology. This essay provides an overview of some of the ways Christian philosophers have deployed immaterialism to solve problems and generate insights in metaphysics, philosophy of mind, philosophy of science, philosophy of religion, and philosophical (...) theology.

This paper considers the alleged pragmatism of Berkeley’s philosophy using the two Sellarsian categories of ‘manifest’ and ‘scientific’ images of the world and human beings. The ‘manifest’ image is regarded as a refinement of the ordinary way of conceiving things, and the scientific image is seen as a theoretical picture of the world provided by science. The paper argues that the so-called Berkeleian pragmatism was an effect of Berkeley’s work towards a synthesis of ‘manifest’ and ‘scientific’ images through the creation (...) of one unified synoptic vision of the world and was a part of a new conceptual framework within which these two images could be combined.
