Throughout his mature writings, Berkeley speaks of minds as substances that underlie or support ideas. After initially flirting with a Humean account, according to which minds are nothing but ‘congeries of Perceptions’, Berkeley went on to claim that a mind is a ‘perceiving, active being... entirely distinct’ from its ideas. Despite his immaterialism, Berkeley retains the traditional category of substance and gives it pride of place in his ontology. Ideas, by contrast, are ‘fleeting and dependent beings’ that must be supported (...) by a mental substance. There is no doubt that Berkeley’s conception of the relationship between minds and ideas is non-traditional, but that fact does not undercut his commitment to the traditional conception of substance. A robust literature has grown up around the thorny issue of reconciling Berkeley’s endorsement of mental substance with his rejection of its material counterpart. (shrink)

George Berkeley, Bishop of Cloyne, was an Irish philosopher and divine who pursued a number of grand causes, contributing to the fields of economics, mathematics, political theory and theology. He pioneered the theory of 'immaterialism', and his work ranges over many philosophical issues that remain of interest today. This volume offers a complete and accurate edition of Berkeley's extant correspondence, including letters written both by him and to him, supplemented by extensive explanatory and critical notes. Alexander Pope famously said 'To (...) Berkeley every virtue under heaven', and a careful reading of the letters reveals a figure worthy of admiration, sheds new light on his personal and intellectual life, and provides insight into the broad historical and philosophical currents of his time. The volume will be an invaluable resource for philosophers, modern historians and those interested in Anglo-Irish culture. (shrink)

The prevailing view about the history of early modern philosophy, which the author dubs “the early modern tale” and wants to convince us is really a fairy tale, has it that the focus on ideas as a solution to various epistemological puzzles, first introduced by Descartes, created difficulties for the traditional ontological scheme of substance and mode. The early modern tale depicts the development of “the way of ideas” as abandoning ontology at least by the time of Berkeley. This, in (...) turn, fostered an antimetaphysical bias as modern philosophy developed further, elevating epistemology to its current primary status in the field. Marc Hight challenges this account by showing how, though the conception of ideas changed over time, the ontological status of ideas remained a central part of the discussion about ideas and influenced how even later thinkers like Locke, Berkeley, and Hume thought about them. By his reading of important texts in early modern philosophy, Hight aims not only to provide a more accurate history of philosophy for this period but also to resuscitate the value of metaphysics for philosophical analysis today.��.

"A wide-ranging study of the 'way of ideas' and its metaphysics, culminating in a bold reinterpretation of Berkeley.".

In 1985, Swiss legal philosopher Walter Ott visited Herbert Hart in Oxford and made this record of their meeting, which casts novel light on some of Hart’s ideas. Ott engaged Hart in a fresh encounter with the legal philosophy of Gustav Radbruch, particularly Hart’s and Radbruch’s reasons for a minimum content of justice in law. They also discussed the grudge informer, state responsibility under laws of an earlier régime, and questions of the definition and falsifiability of legal theories. Hart (...) surprisingly reported Hans Kelsen as stating, when they had met at Berkeley in 1961, that Hume (and not Kant, and certainly not Wittgenstein) was the greatest philosopher who had ever lived. The translation is accompanied with annotations explaining references, assumptions and contexts. (shrink)

: Establishing and defending the Christian faith serves as both a guide and a limit to Berkeley's intriguing metaphysics. I take Berkeley seriously when he says that his aim is to promote the consideration of God and the truth of Christianity. In this paper I discuss and engage Berkeley's superficially weak argument (which I call the natural analogy argument) in defense of the plausibility of the doctrine of bodily resurrection. When his immaterialist resources are properly applied, the argument has more (...) merit than one might initially believe. I conclude by speculating that Berkeley had reason to believe that immaterialism was a better fit with Christianity than materialism. (shrink)

In this article we argue that an immaterialist ontology -- a metaphysic that denies the existence of material substance -- is more consonant with Christian dogma than any ontology that includes the existence of material substance. We use the philosophy of the famous eighteenth-century Irish immaterialist George Berkeley as a guide while engaging one particularly difficult Christian mystery: the doctrine of the Incarnation of Christ. The goal is to make plausible the claim that, from the analysis of this one example, (...) there are strong reasons for thinking that if one wants to be a Christian one ought to be an immaterialist. (shrink)

I draw attention to a group of thinkers in Ireland in the first half of the eighteenth century that made significant contributions to the philosophy of political economy. Loosely organized around the Dublin Philosophical Society founded in 1731, these individuals employed a similar set of assumptions and shared a common interest in the well-being of the Irish people. I focus on Samuel Madden, Arthur Dobbs, and Thomas Prior and argue for two main theses. First, these Irish thinkers shared a number (...) of commonalities with the English mercantilist thinkers of the eighteenth century, and to the degree that they did, their proposals to aid Ireland and reduce poverty were largely doomed to failure. Second, these Irish thinkers also importantly diverged from typical eighteenth-century mercantilist thinking in several ways. These modifications to mercantilism resulted in large part from the unusual political situation of Ireland and helped orient their economic thinking along more institutional lines. In particular, the emphasis of the Irish on full employment and on the modification of social as well as political institutions is an early step forward in making political economy more sophisticated.

The seventeenth century witnesses the demise of two core doctrines in the theory of perception: naive realism about color, sound, and other sensible qualities and the empirical theory, drawn from Alhacen and Roger Bacon, which underwrote it. This created a problem for seventeenth century philosophers: how is that we use qualities such as color, feel, and sound to locate objects in the world, even though these qualities are not real? -/- Ejecting such sensible qualities from the mind-independent world at once (...) makes for a cleaner ontology, since bodies can now be understood in purely geometrical terms, and spawns a variety of fascinating complications for the philosophy of perception. If sensible qualities are not part of the mind-independent world, just what are they, and what role, if any, do they play in our cognitive economy? We seemingly have to use color to visually experience objects. Do we do so by inferring size, shape, and motion from color? Or is it a purely automatic operation, accomplished by divine decree? -/- This volume traces the debate over perceptual experience in early modern France, covering such figures as Antoine Arnauld, Robert Desgabets, and Pierre-Sylvain Regis alongside their better-known countrymen Rene Descartes and Nicolas Malebranche.

This work studies early modern thought concerning the ontology of ideas. I endeavor to establish, contrary to some current scholarship, that the Early Moderns remained firmly in the grip of a substance/mode ontology narrowed from the substance/property distinction inherited from Aristotle. I argue that this traditional dichotomy provides the most philosophically and historically fruitful approach to understanding early modern thought. In particular, I demonstrate how the increasing radicalization in the metaphysics of the moderns is best explained by remaining within the (...) substance/mode ontology. Competing contemporary approaches, especially ones that attempt to employ concepts such as reification and object talk in place of the traditional ontology, do not sufficiently penetrate to the core issues facing the Moderns. Rather than seeking to abandon the categories of substance and mode, the Moderns sought, perhaps vainly, to find room for ideas within it. I proceed by providing background from Aristotle and the Medievals, go on to discuss the philosophical views of Descartes, Malebranche, Arnauld, Locke and Berkeley. The development of idea philosophy culminates in Berkeley, who creates a hybrid ontic category I call 'quasi-substance.' Ideas for Berkeley are ontically dependent on minds , but external to them in the sense that the relationship between ideas and minds are two-place . I demonstrate how this understanding explains the radical metaphysical positions he takes, especially his commitment to perceptual heterogeneity. I conclude that rather than abandoning the traditional ontic categories, the Moderns adhered to them desperately, and thus are best understood through them. (shrink)

According to the phenomenal intentionality research program, a state’s intentional content is fixed by its phenomenal character. Defenders of this view have little to say about just how this grounding is accomplished. I argue that without a robust account of representation, the research program promises too little. Unfortunately, most of the well-developed accounts of representation – asymmetric dependence, teleosemantics, and the like – ground representation in external relations such as causation. Such accounts are inconsistent with the core of the phenomenal (...) intentionality program. I argue that, however counter-intuitive it may seem, the best prospect for explaining how phenomenal character represents appeals to resemblance. (shrink)

Of all of Berkeley’s claims about perception, perhaps the most unusual is his assertion that we do not see the numerically same objects we feel. Ideas are radically heterogeneous. The question I seek to answer is why Berkeley thought this thesis true. Traditional accounts hold that Berkeley was forced into accepting heterogeneity by his views concerning either distance or abstraction, but careful analysis reveals these to be mistaken. I conclude that how Berkeley thought of the ontic status of ideas finishes (...) the incomplete picture provided by traditional accounts, and supplies us with a better under‐standing of his views on perceptual heterogeneity.

The conception of a ‘law of nature’ is a human product. It was created to play a role in natural philosophy, in the Cartesian tradition. In light of this, philosophers and scientists must sort out what they mean by a law of nature before evaluating rival theories and approaches. If one’s conception of the laws of nature is yoked to metaphysical notions of truth and explanation, that connection must be made explicit and defended. If, on the other hand, one’s aim (...) is to disentangle laws from truth or from explanation, that must be stated and defended as well. If philosophers do not make such assumptions, intuitions, and methodological commitments clear, then it will be impossible to identify the source of disagreement in debates about the laws of nature. Are the conflicts rooted in disagreement about the conclusions reached, or do the background commitments of the combatants block any resolution to the dispute in principle or in practice? (shrink)

George Berkeley's New Theory of Vision is frequently read as a simple precursor or “half-way house” to his later metaphysics. As a result, some allege the value of the New Theory has been overlooked as critics judge it by its association with immaterialism. In this piece I examine the ongoing debate over the nature of the connection between Berkeley's early work on perception and his later immaterialist tracts. I identify four principal positions on the nature of the connection that have (...) been advanced in the scholarly literature, critically engage the evidence for and against them, and finally weigh in by arguing that an excellent case can be made for thinking that the New Theory is a half-way house to immaterialism after all. (shrink)

I argue that Berkeley has reasonable grounds for believing both that (a) the supposition of the existence of material substance leads to atheism and (b) endorsing immaterialism provides a better support for the Christian faith than any rival that posits the existence of matter. Together, those claims lead to the conclusion that if one wants to be a Christian, there is good reason to think that one ought to be an immaterialist. Je montre que Berkeley a raison de croire que (...) l'existence de la matière conduit à l'athéisme et que la reconnaissance de l'immatérialisme donne un meilleur support à la croyance chrétienne que n'importe quelle autre assertion qui défend l'existence de la matière. Ensemble ces thèses mènent à la conclusion que pour qui veut être chrétien, il y a une bonne raison de croire qu'il faut être immatérialiste. (shrink)

This book examines John Locke's claims about the nature and workings of language. Walter Ott proposes an interpretation of Locke's thesis in which words signify ideas in the mind of the speaker, and argues that rather than employing such notions as sense or reference, Locke relies on an ancient tradition that understands signification as reliable indication. He then uses this interpretation to explain crucial areas of Locke's metaphysics and epistemology, including essence, abstraction, knowledge and mental representation. His discussion challenges (...) many of the orthodox readings of Locke, and will be of interest to historians of philosophy and philosophers of language alike. (shrink)

On a currently popular reading of Locke, an idea represents its cause, or what God intended to be its cause. Against Martha Bolton and my former self (among others), I argue that Locke cannot hold such a view, since it sins against his epistemology and theory of abstraction. I argue that Locke is committed to a resemblance theory of representation, with the result that ideas of secondary qualities are not representations.

A number of studies have demonstrated pragmatic language difficulties in people with Schizophrenia Spectrum and Other Psychotic Disorders. However, research about how people with schizophrenia spectrum and other psychotic disorders understand scalar implicatures is surprisingly rare, since SIs have generated much of the most recent literature. Scalar implicatures are pragmatic inferences, based on linguistic expressions like some, must, or, which are part of a scale of informativeness. Logically, the less informative expressions imply the more informative ones, but pragmatically people usually (...) infer that the presence of a less informative term implies that the more informative term was not applicable. In one of the few existing studies with people with schizophrenia spectrum and other psychotic disorders, Wampers et al. observed that in general, people with schizophrenia spectrum and other psychotic disorders were less likely to derive SIs than controls. The current study has three main aims. First, we want to replicate the original finding with the scalar terms some-all. Second, we want to investigate how these patients deal with different scalar terms, that is, we want to investigate if scalar diversity is also observed in this clinical group. Third, we investigate the role of working memory, often seen as another important mechanism to enable inferring SIs. Twenty-one individuals with a psychotic disorder and 21 matched controls answered 54 under-informative statements, in which seven different pairs of scalar terms were used. In addition, working memory capacity was measured. Patients with schizophrenia spectrum and other psychotic disorders did not make more logical interpretations when processing quantifiers, disconfirming Wampers et al.. However, certain scalar scales elicited more pragmatic interpretations than others, which is in line with the scalar diversity hypothesis. Additionally, we observed only partial evidence for the role of working memory. Only for the scalar scale and-or, a significant effect of working memory was observed. The implications of these results for patients with schizophrenia spectrum and other psychotic disorders are discussed, but also the role of working memory for pragmatic inferences, as well as the place of SIs in experimental pragmatics.

John Locke’s claims about relations (such as cause and effect) and mixed modes (such as beauty and murder) have been controversial since the publication of the Essay. His earliest critics read him as a thoroughgoing anti-realist who denies that such things exist. More charitable readers have sought to read Locke’s claims away. Against both, I argue that Locke is making ontological claims, but that his views do not have the absurd consequences his defenders fear. By examining Locke’s texts, as well (...) as the intellectual context in which they were written, I show that Locke’s position is at once radical and thoroughly traditional. (shrink)

Philosophers of the modern period are often presented as having made an elementary error: that of confounding the attitude one adopts toward a proposition with its content. By examining the works of Locke and the Port-Royalians, I show that this accusation is ill-founded and that Locke, in particular, has the resources to construct a theory of propositional attitudes.

Despite their influence on later philosophers such as Hume, Malebranche's central arguments for occasionalism remain deeply puzzling. Both the famous ‘no necessary connection’ argument and what I call the epistemic argument include assumptions – e.g., that a true cause is logically necessarily connected to its effect – that seem unmotivated, even in their context. I argue that a proper understanding of late scholastic views lets us see why Malebranche would make this assumption. Both arguments turn on the claim that a (...) volition is the only candidate for a cause, because only a volition can include an effect as its intentional content. (shrink)

It can seem obvious that we live in a world governed by laws of nature, yet it was not until the seventeenth century that the concept of a law came to the fore. Ever since, it has been attended by controversy: what does it mean to say that Boyle's law governs the expansion of a gas, or that the planets obey the law of gravity? Laws are rules that permit calculations and predictions. What does the universe have to be like, (...) if it is to play by them? This book sorts the most prominent answers into three families. Laws first arose in a theological context; they govern events only because God enforces them. Those wishing to reverse the order of explanation, and argue that the powers of objects fix the laws, struggled to claim for themselves the results of new science. The stand-off between these two families bred a third which rejects any kind of enforcer for the laws. On this view, laws summarize events; they do not govern anything. This book traces the fortunes of the three families, from their origins to the present day. It uses objections - and the revisions needed to answer them - to produce the best representative of each. Along the way, it tries to settle the rules of this game, the debate over laws of nature. What should we expect from an account of laws? The book aims to help readers develop their own desiderata and judge the merits of the competing positions. (shrink)

The popular Cartesian reading of George Berkeley's philosophy of mind mischaracterizes his views on the relations between substance and essence and between an idea and the act of thought in which it figures. I argue that Berkeley rejects Descartes's tripartite taxonomy of distinctions and makes use of a fourth kind of distinction. In addition to illuminating Berkeley's ontology of mind, this fourth distinction allows us to dissolve an important dilemma raised by Kenneth Winkler.

Hume's views on language have been widely misunderstood. Typical discussions cast Hume as either a linguistic idealist who holds that words refer to ideas or a proto-verificationist. I argue that both readings are wide of the mark and develop my own positive account. Humean signification emerges as a relation whereby a word can both indicate ideas in the mind of the speaker and cause us to have those ideas. If I am right, Hume offers a consistent view on meaning that (...) is neither linguistic idealism nor positivism but a genuine alternative to these, one that deserves to be taken seriously. (shrink)

Contemporary Humeans treat laws of nature as statements of exceptionless regularities that function as the axioms of the best deductive system. Such ‘Best System Accounts’ marry realism about laws with a denial of necessary connections among events. I argue that Hume’s predecessor, George Berkeley, offers a more sophisticated conception of laws, equally consistent with the absence of powers or necessary connections among events in the natural world. On this view, laws are not statements of regularities but the most general rules (...) God follows in producing the world. Pace most commentators, I argue that Berkeley’s view is neither instrumentalist nor reductionist. More important, the Berkeleyan Best System can solve some of the problems afflicting its Humean rivals, including the problems of theory choice and Nancy Cartwright’s ‘facticity’ dilemma. Some of these solutions are available in the contemporary context, without any appeal to God. Berkeley’s account deserves to be taken seriously in its own right. (shrink)

I claim that Berkeley's main argument against abstraction comes into focus only when we see Descartes as one of its targets. Berkeley does not deploy Winkler's impossibility argument but instead argues that what is impossible is inconceivable. Since Descartes conceives of extension as a determinable, and since determinables cannot exist as such, he falls within the scope of Berkeley's argument.

The way of laws is as much a defining feature of the modern period as the way of ideas; but the way of laws is hardly without its forks. Both before and after Descartes, there are philosophers using the concept to carve out a very different position from his, one that is entirely disconnected from God or God’s will. I argue that Francis Bacon and Baruch Spinoza treat laws as dispositions that derive from a thing’s nature. This reading upends the (...) currently orthodox treatment of Spinoza’s laws as infinite modes, and calls for a re-conception of his metaphysics of causation. (shrink)

Discussions of John Locke’s theory of causation tend, understandably, to focus on the related notion of power and in particular the dialectic with David Hume. But Locke faces a very different threat, one that is internal to his view. For he argues both that causation is a relation and that relations are not real. The obvious conclusion is intolerable. And yet the premises, I argue, are unassailable. Building on an interpretation of Locke’s treatment of relations I have developed elsewhere, I (...) show how Locke can at once speak meaningfully of causation and deny its mind-independent existence. (shrink)

I argue that Leibniz’s doctrine of sensory representation is intended in part to close an explanatory gap in his philosophical system. Unlike the twentieth century explanatory gap, which stretches between neural states on one side and phenomenal character on the other, Leibniz’s gap lies between experiences of secondary qualities like color and taste and the objects that cause them. The problem is that the precise arrangement and distribution of such experiences can never be given a full explanation. In response, Leibniz (...) appeals to representation. I argue that the sense in which Leibnizian sensations are representations is too weak to close his explanatory gap. In the end, he must appeal to the doctrine of the best possible world. (shrink)

I argue that Aristotle endorses what I call the ‘strong link thesis’: the claim that virtuous and vicious acts are voluntary just in case the character states from which they flow are voluntary. Pace much of the literature, I argue that Aristotle does not defend some kind of limited or qualified responsibility for character: rightly or wrongly, he believes, and must believe, that character states are voluntary, full stop.

Unlike many of Descartes’s other followers, Pierre-Sylvain Re´gis resists the temptations of occasionalism. By marrying the ontology of mechanism with the causal structure of concurrentism, Re´gis arrives at a novel view that both acknowledges God’s role in natural events and preserves the causal powers of bodies. I set out Re´gis’s position, focusing on his arguments against occasionalism and his responses to Malebranche’s ‘no necessary connection’ and divine concursus arguments.

Like their contemporary counterparts, early modern philosophers find themselves in a predicament. On one hand, there are strong reasons to deny that sensations are representations. For there seems to be nothing in the world for them to represent. On the other hand, some sensory representations seem to be required for us to experience bodies. How else could one perceive the boundaries of a body, except by means of different shadings of color? I argue that Nicolas Malebranche offers an extreme -- (...) and ultimately unworkable -- attempt to solve this riddle. Most commentators claim that Malebranche defends an adverbial theory of sensation, according to which a sensation is merely a way in which an act of sensing happens. The adverbial reading is wrong, or so I argue. Once we arrive at a more accurate reading, we shall see that his position is much more strange than is currently thought. Nevertheless, Malebranche’s view is similar to the adverbial theory in one respect, albeit it at a very high level of generality. His view thus inherits two of the main problems that afflict adverbial theories. Although Malebranche fails to solve them, his ingenious attempts to do so are instructive. (shrink)

On the face of it, Locke rejects the scholastics' main tool for making sense of talk of God, namely, analogy. Instead, Locke claims that we generate an idea of God by 'enlarging' our ideas of some attributes (such as knowledge) with the idea of infinity. Through an analysis of Locke's idea of infinity, I argue that he is in fact not so distant from the scholastics and in particular must rely on analogy of inequality.

Two kinds of people might find this useful: first, those interested in the modern debate over ideas and representation who don’t happen to read French, or who do, but would like to have in one place the relevant excerpts, to see whether looking at the originals is worth their time. Second are teachers of modern philosophy. The back-and-forth among these figures makes for a refreshing change from the massive, often self-contained works that characterize much of the rest of such a (...) course. For example, one could easily work in chapter 3 (the high point of the debate, from my point of view) between Descartes and Berkeley. (shrink)

This article canvases the main areas of controversy: the nature of Lockean signification and his position on propositions and particles.

How language works — its functions, mechanisms, and limitations — matters to the early moderns as much as it does to contemporary philosophers. Many of the moderns make reflection on language central to their philosophical projects, both as a tool for explaining human cognition and as a weapon to be used against competing views. Even in philosophers for whom language is less central, we can find important connections between their views on language and their other philosophical commitments.

Much recent philosophy of perception is preoccupied with finding a place for phenomenal character in a physical world. By contrast, Locke’s philosophy of sensory perception is an episode in his ‘Historical, plain method’ and seeks to map out the processes by which we experience ordinary objects. On Locke’s account, our ideas of primary and secondary qualities enter the mind ‘simple and unmixed’; having an idea of a colour, for example, is not necessary for the visual experience of a shape. An (...) analysis of the Molyneux problem reveals that, for Locke, judgment corrects the initial two-dimensional idea vision presents us with. Nevertheless, Locke’s position is problematic: he has no account of how we pair ideas of primary and secondary qualities, nor of how we could experience a colourless visual idea of shape. (shrink)

This paper addresses the following questions: (a) what did Locke mean when he said that ‘words signify ideas’? and (b) what is Locke’s argument for this thesis, and how successful is it? The paper argues that the two most prominent interpretations, those of Norman Kretzmann and E. J. Ashworth, attribute to Locke an argument for his semantic thesis that is fallacious, and that neither can make good sense of two key passages in book 3 of the Essay concerning Human Understanding. (...) An alternative understanding of signification, drawn from the works of Hobbes and the Port-Royal logicians, is explored and shown to provide both a satisfactory interpretation of these two passages and an understanding of Locke’s argument for the thesis that absolves him of fallacy.
