The Oxford Handbook of Berkeley is a compendious examination of a vast array of topics in the philosophy of George Berkeley, Anglican Bishop of Cloyne, the famous idealist and most illustrious Irish philosopher. Berkeley is best known for his denial of the existence of material substance and his insistence that the only things that exist in the universe are minds and their ideas; however, Berkeley was a polymath who contributed to a variety of different disciplines, not well distinguished from philosophy in the eighteenth century, including the theory and psychology of vision, the nature and functioning of language, the debate over infinitesimals in mathematics, political philosophy, economics, chemistry, and theology. This volume includes contributions from thirty-four expert commentators on Berkeley's philosophy, some of whom provide a state-of-the-art account of his philosophical achievements, and some of whom place his philosophy in historical context by comparing and contrasting it with the views of his contemporaries, as well as with philosophers who preceded him and others who succeeded him.

An important part of Hume's philosophy is grounded in a fundamental distinction between two kinds of perceptions: impressions and ideas. Existing views of the distinction are that the former are livelier than the latter, that the former are causally prior to the latter, that the latter are copies of the former, that the former but not the latter are perceptions of an objective realm, and that the former are feelings whereas the latter are thoughts. I argue that all of these views of the distinction are problematic and should be replaced by the Reflection view, according to which (simple) ideas are, while impressions are not, the direct products of reflection on other perceptions.

This article describes and defends an inclusive anti-canonical approach to the study of the history of philosophy. Its proposal, based on an analysis of the nature of the history of philosophy and the value of engaging in the practice, is this: The history of philosophy is the history of rationally justified, systematic answers to philosophical questions; studying this subject is both intrinsically and instrumentally valuable; these benefits do not derive from the imposition of a canon—indeed, there should be no canon; the absence of a canon leaves room for a thousand courses on a thousand different topics with a thousand different narrative structures; but a good syllabus should be relevantly diverse in a way that fits the thematic arc of the course; and this prescription for the discipline is inclusive, in ways that can only strengthen and enliven it for future generations.

In 1827, Lady Mary Shepherd published Essays on the Perception of an External Universe, which offers both an argument for the existence of a world of external bodies existing outside our minds and a criticism of Berkeley's argument for idealism in A Treatise Concerning the Principles of Human Knowledge. In this paper, I evaluate Margaret Atherton's criticisms of Shepherd's case against Berkeley, and provide reasons for thinking that, although Shepherd's particular criticisms of Berkeley do not succeed, she correctly identifies an important problem to which Berkeley's reasoning is subject.

There is a mystery at the heart of Plato's Parmenides. In the first part, Parmenides criticizes what is widely regarded as Plato's mature theory of Forms, and in the second, he promises to explain how the Forms can be saved from these criticisms. Ever since the dialogue was written, scholars have struggled to determine how the two parts of the work fit together. Did Plato mean us to abandon, keep or modify the theory of Forms, on the strength of Parmenides' criticisms? Samuel Rickless offers something that has never been done before: a careful reconstruction of every argument in the dialogue. He concludes that Plato's main aim was to argue that the theory of Forms should be modified by allowing that forms can have contrary properties. To grasp this is to solve the mystery of the Parmenides and understand its crucial role in Plato's philosophical development.

In a focused assessment of one of the founding members of the liberal tradition in philosophy and a self-proclaimed “Under-Labourer” working to support the scientific revolution of the seventeenth century, the author maps the full range of John Locke’s highly influential ideas, which even today remain at the heart of debates about the nature of reality and our knowledge of it, as well as our moral and political rights and duties. Comprehensive introduction to the full range of Locke’s ideas, providing an up-to-date account that acknowledges issues raised by recent scholarship over the past decade A well-rounded perspective on one of the intellectual giants of the western philosophical tradition Provides detailed coverage of Locke’s two key works, _An Essay Concerning Human Understanding_ and _The Two Treatises of Government_. A sophisticated analysis by a highly respected academic A vital addition to the _Blackwell_ _Great Minds_ series.

Gottlob Frege and Bertrand Russell once argued over whether Mont Blanc is a constituent of the proposition that Mont Blanc is more than four thousand meters high. Russell thought so, but Frege disagreed. The debate has been with us ever since. ;Let us say that the content of a linguistic expression E is the entity contributed by E to the proposition expressed by a sentence of which E is a part. Russell's point, more generally, was that the content of a proper name, indexical or demonstrative is identical to its referent. By contrast, Frege argued that the contents of such expressions are representations of their referents. ;According to Descriptivism, the most influential version of Fregeanism, the Sinn of an expression E is a uniquely satisfiable property, and the referent of E is the entity that satisfies this property. In recent years, however, Descriptivism has fallen on hard times. But contemporary Russellians face problems of their own, such as the need to explain how some sentences containing empty names can be true, or how some identity-sentences can be informative. ;The main thesis of this dissertation is that the contents of linguistic expressions are varied in kind and in function: whereas proper names and some demonstratives have representational contents, the contents of first-person pronouns and that-clauses are identical to their referents. In defense of a limited non-Descriptivist Fregeanism , I argue, in particular, that proper names are their own contents, and that the contents of perceptual demonstratives are perceptual representations. Taken together, these theses may be used to solve numerous puzzles in the literature, including the puzzles faced by Russellians, Saul Kripke's puzzle about belief, and Mark Richard's "phone-booth" puzzle. ;One lesson of this investigation is that we should not look for theoretical uniformity where it does not exist. That the contents of our words should differ in nature is not surprising: content is the object of cognition, and the modes of cognition vary in accordance with the types of objects to which we have cognitive access

One of the more interesting philosophical debates in the seventeenth century concerned the nature and explanation of qualities. In order to understand these debates, it is important to place them in their proper historical-philosophical context. This book chapter starts with theoretical background in the work of Aristotle and the atomists, and then moves on to survey various theories of motion and rest, light, color, and sound, as well as the distinction between primary and secondary qualities, as represented in the work of such figures as Berkeley, Boyle, Charleton, Cordemoy, Descartes, Desgabets, Galileo, Gassendi, Hobbes, Locke, Malebranche, Newton, Régis, Rohault, and Sennert.

George Berkeley maintains both anti-abstractionism (that abstract ideas are impossible) and idealism (that physical objects and their qualities are mind-dependent). Some scholars (including Atherton, Bolton, and Pappas) have argued, in different ways, that Berkeley uses anti-abstractionism as a premise in a simple argument for idealism. In this paper, I argue that the relation between anti-abstractionism and idealism in Berkeley's metaphysics is more complex than these scholars acknowledge. Berkeley distinguishes between two kinds of abstraction, singling abstraction and generalizing abstraction. He then rests his case for idealism, not on the denial of the possibility of generalizing abstraction, but rather on the denial of the possibility of singling abstraction. Moreover, Berkeley's argument does not rest on a blanket rejection of all forms of singling abstraction. Rather, the fundamental anti-abstractionist assumption, for his purposes, is the claim that primary qualities cannot be mentally singled out from secondary qualities. Crucially, the claim that the existence of physical objects cannot be mentally singled out from their being perceived is not a premise in, but rather a consequence of, Berkeley's argument for idealism. Berkeley's argument therefore avoids circularity inasmuch as it appeals to the impossibility of singly abstracting one idea in order to establish the impossibility of singly abstracting another

There are two major semantic theories of proper names: Semantic Descriptivism and Direct Reference. According to Semantic Descriptivism, the semantic content of a proper name N for a speaker S is identical to the semantic content of a definite description “the F” that the speaker associates with the name. According to Direct Reference, the semantic content of a proper name is identical to its referent. Semantic Descriptivism suffers from a number of drawbacks first pointed out by Donnellan (1970) and Kripke (1972). Direct Reference faces difficulties of its own, most importantly the problem of empty names. The most promising Directly Referential solution to this problem is the Unfilled Proposition view, according to which utterances of sentences containing empty names semantically express unfilled propositions. But this view faces the problem of accounting for the intuition that negative existentials involving empty names are true. The most promising way of dealing with this problem within Unfilled Proposition theory is to suppose (i) that utterances of sentences may be used to pragmatically convey propositions they do not semantically express, and (ii) that the proposition pragmatically conveyed by a speaker S's utterance of a sentence containing an empty name N (where “the F” is a definite description S associates with N) is identical to the proposition semantically expressed by an utterance of the sentence obtained by replacing N with “the F”. Call this view “Pragmatic Descriptivism”. With respect to the problem of negative existentials, Pragmatic Descriptivists can insist that, although an utterance of “Santa does not exist” is literally neither true nor false, our taking it to be true may be explained as the result of our having confused the unfilled proposition it semantically expresses with the clearly true descriptive proposition it pragmatically conveys. Despite its theoretical virtues, Pragmatic Descriptivism has recently come under fire. Everett (2003), in particular, has advanced four different lines of criticism, to which Adams and Dietrich (2004) have responded in some detail. In this article, I have two main aims. The first is to argue that Adams and Dietrich's replies to Everett's criticisms (with one exception) are ineffective. I conclude that there is no acceptable strategy for solving the problem of empty names within Direct Reference theory. The second is to argue that there is a promising alternative to Semantic Descriptivism and Direct Reference that requires us to fill unfilled propositions with names, thereby solving the problem of empty names.

Marc A. Hight has given us a well-researched, well-written, analytically rigorous and thoughtprovoking book about the development of idea ontology in the seventeenth and early eighteenth centuries. The book covers a great deal of material, some in significant depth, some not. The figures discussed include Descartes, Malebranche, Arnauld, Locke, Leibniz, Berkeley, and Hume. Some might think it a tall order for anyone to grapple with the central works of these figures on a subject as fundamental as the nature of ideas. And while reading the book, I must admit to having had this thought a few times. Seventeen pages on Descartes’ theory of ideas, covering the development of his ontology of ideas, the distinction between formal reality and objective reality, the nature of mental representation, the contagion theory of causation, the doctrine of innate ideas as ungrounded dispositions, and the interactionism/occasionalism controversy? Wow. And yet Hight has done his homework. He knows the figures and the relevant interpretive controversies well, he focuses on many of the passages that are relevant to the book’s central thesis, and in the end offers us a compelling narrative as an alternative to what he identifies as “the traditional view of what transpired in the early modern period” (2).

The vast majority of philosophers and legal theorists who have thought about the issue agree that there is such a thing as a moral right to privacy. However, there is little or no theoretical consensus about the nature of this right. According to reductionists, the right to privacy amounts to nothing more than a cluster of property rights and rights over the person, and therefore plays no autonomous explanatory role in moral theory (Thomson 1975, Davis 1959). Among non-reductionists, there are almost as many accounts of the right to privacy as there are synagogues in the old town of Jerusalem. For one group of non-reductionists (perhaps the majority), the right to privacy is properly understood as a right of control, a form of autonomy. Within this group, some think that the right to privacy is the right to control information about oneself (Westin 1967, Beardsley 1971, Gerstein 1978, Fried 1970, Moore 2003), while others insist that it is the right to control access to oneself (Parker 1974, Scanlon 1975, Rachels 1975, Reiman 1976, Van den Haag 1971). For another group of non-reductionists, the right to privacy is the right to cognitive and/or physical inaccessibility (Gavison 1980, Garrett 1974, Allen 1988). Though these are by far the most widely adopted non-reductionist accounts of the relevant right, they are by no means the only ones currently on offer. There are hybrid accounts according to which the right to privacy is a cluster of various rights of control (Inness 1992) or a cluster of various rights of control and restricted access (DeCew 1997). And according to an influential “information-based” account, the right to privacy 1 is defined as the right that others not possess undocumented personal information about the right-holder (Parent 1983a; 1983b). The purpose of this paper is to bring some order to this theoretical chaos. On my view, none of these accounts of the right to privacy is accurate..

There are two major semantic theories of proper names: Semantic Descriptivism and Direct Reference. According to Semantic Descriptivism, the semantic content of a proper name N for a speaker S is identical to the semantic content of a definite description “the F” that the speaker associates with the name. According to Direct Reference, the semantic content of a proper name is identical to its referent. As is well known, Semantic Descriptivism suffers from a number of drawbacks first pointed out by Donnellan (1970) and Kripke (1972).1 The first difficulty is semantic: in many cases, the definite description that S associates with N (if it denotes) denotes an entity other than the referent of N. The second difficulty is epistemic: in many cases, contrary to what Semantic Descriptivism predicts, an utterance of “N=the F” does not semantically express a proposition that is knowable a priori. And the third difficulty is modal: although Semantic Descriptivism entails that the proposition semantically expressed by an utterance of “N=the F” is metaphysically necessary, in many cases the relevant proposition is actually metaphysically contingent. Direct Reference faces three main difficulties of its own. First, there is the problem of cognitive significance (or, as it has come to be known, Frege’s Puzzle): if the content of a proper name is its referent, then different proper names have the same content, and hence utterances of “N=M” and “N=N” semantically express the same proposition; yet these two utterances differ in cognitive significance, and it would seem 1 that utterances semantically expressing the same proposition should not differ in cognitive significance. Second, there is the problem of substitution: if the content of a proper name is its referent, then co-referential proper names should be intersubstitutable in propositional attitude contexts salva veritate; yet linguistic intuitions suggest that substitution of co-referential proper names in such contexts often fails to preserve truthvalue..

According to the Doctrine of Doing and Allowing, it is more difficult to justify doing harm than it is to justify allowing harm. Enabling harm consists in withdrawing an obstacle that would, if left in place, prevent a pre-existing causal sequence from leading to foreseen harm. There has been a lively debate concerning the moral status of enabling harm. According to some (e.g. McMahan, Vihvelin and Tomkow), many cases of enabling harm are morally indistinguishable from doing harm. Others (e.g. Foot, Hanser) support the Equivalence Hypothesis, according to which enabling harm is morally equivalent to allowing harm. Here I argue that there is every reason to embrace, and no reason to reject, the Equivalence Hypothesis

In the 17th century, there was a lively debate in the intellectual circles with which Locke was familiar, revolving around the question whether the human mind is furnished with innate ideas. Although a few scholars declared that there is no good reason to believe, and good reason not to believe, in the existence of innate ideas, the vast majority took for granted that God, in his infinite goodness and wisdom, has inscribed in human minds innate principles that constitute the foundation of knowledge, as well in practical as in theoretical matters. It was in opposition to the latter group, which included Descartes, leading Anglican divines, and the Cambridge Platonists, that Locke directed his attack upon innate ideas in the first book of the Essay.1 In the minds of those who weighed in on one side or the other, the importance of the controversy related to epistemological, moral, and religious doctrines. At the epistemological level, innatists (or, as I will also call them, nativists) held that all knowledge of the natural and supernatural world available to humans is based on fundamental “speculative” axioms, theoretical principles that neither require nor are capable of proof. These principles, such as the causal principle – that nothing comes from nothing – or the principle of non-contradiction – that nothing can both be and not be at the same time, were taken to be both universal and necessary, and hence impossible to derive from experience. To the mind of an innatist, if these principles are not based on experience and are not (as chimerical ideas were thought to be) constructed out..

The Parmenides is, quite possibly, the most enigmatic of Plato's dialogues. The dialogue recounts an almost certainly fictitious conversation between a venerable Parmenides (the Eleatic Monist) and a youthful Socrates, followed by a dizzying array of interconnected arguments presented by Parmenides to a young and compliant interlocutor named “Aristotle” (not the philosopher, but rather a man who became one of the Thirty Tyrants after Athens' surrender to Sparta at the conclusion of the Peloponnesian War). Most commentators agree that Socrates articulates a version of the theory of forms defended by his much older namesake in the dialogues of Plato's middle period, that Parmenides mounts a number of potentially devastating challenges to this theory, and that these challenges are followed by a piece of intellectual “gymnastics” consisting of eight strings of arguments (Deductions) that are in some way designed to help us see how to protect the theory of forms against the challenges. Beyond this, there is precious little scholarly consensus. Commentators disagree about the proper way to reconstruct Parmenides' challenges, about the overall logical structure of the Deductions, about the main subject of the Deductions, about the function of the Deductions in relation to the challenges, and about the final philosophical moral of the dialogue as a whole

In this paper, I provide what I believe to be Descartes's own solution to the problem of the Cartesian Circle. As I argue, Descartes thinks he can have certain knowledge of the premises of the Third Meditation proof of God's existence and veracity (i.e., the 3M-Proof) without presupposing God's existence. The key, as Broughton (1984) once argued, is that the premises of the 3M-Proof are knowable by the natural light. The major objection to this "natural light" gambit is that Descartes identifies the natural light with the faculty of clear and distinct perception, a faculty that cannot be known to be reliable in advance of the 3M-Proof. I explain that Descartes distinguishes between three kinds of clear and distinction perceptions depending on their source; the senses, the imagination, or the intellect. I claim that although the First Meditation is designed to cast doubt on the clear and distinct perceptions of the senses and of the imagination, it is not designed to cast doubt on the clear and distinct perceptions of the intellect. The "natural light" gambit relies on the assumption that the natural light, by which propositions can be certainly known without presupposing knowledge of God's existence, is to be identified with the faculty of *intellectual* clear and distinct perception.

In the Protagoras, Socrates appears to affirm and defend a paradoxical doctrine: the unity of virtue. Plato scholars do not agree on how the doctrine should be understood. Some, following Vlastos (1972), take Socrates to hold that the virtues are biconditionally related, i.e. that anyone who has one of the virtues has them all. Others, following Penner (1973), take Socrates’ position to be that the names of the virtues all refer to the same thing, namely virtue. In this paper, I argue that both of these interpretations are mistaken: the main thesis of the Protagoras is, very simply, that each of the virtues is a kind of knowledge or wisdom.
