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)

During the seventeenth century the major cognitive faculties--sense, imagination, memory, and understanding or intellect--became the central focus of argument in metaphysics and epistemology to an extent not seen before. The theory of the intellect, long an important auxiliary to metaphysics, became the focus of metaphysical dispute, especially over the scope and powers of the intellect and the existence of a `pure' intellect. Rationalist metaphysicians such as Descartes, Spinoza, and Malebranche claimed that intellectual knowledge, gained independently of the senses, provides the (...) framework for constructing a new theory of nature. Other writers, including Hobbes and the early Gassendi, denied the existence of a distinct intellectual faculty, and so challenged the metaphysicians' abilities directly to perceive the essences of substances. The theory of the senses, which had long been a part of philosophical discussion, took on a new urgency, for adherents of the new corpuscularian philosophy needed to replace the dominant Aristotelian theory of real sensory qualities and sensible species. The revival of skepticism and a renewed interest in method also brought the faculties into prominence, for skeptical challenges typically were directed toward the faculties of sense and understanding, and the theory of method was conceived as providing instructions for the proper use of one's cognitive equipment. The theory of the faculties, then, is an important key to theories of knowledge in the seventeenth century. Indeed, rather than speaking of seventeenth century epistemology, it would be less anachronistic and more informative to speak of theories of cognition. The familiar (and over-stated) point that epistemology became fundamental to metaphysics during that century can then be restated as the point that the theory of faculties became central in metaphysical dispute.

Philosophical discussions of Molyneux's problem within contemporary philosophy of mind tend to characterize the problem as primarily concerned with the role innately known principles, amodal spatial concepts, and rational cognitive faculties play in our perceptual lives. Indeed, for broadly similar reasons, rationalists have generally advocated an affirmative answer, while empiricists have generally advocated a negative one, to the question Molyneux posed after presenting his famous thought experiment. This historical characterization of the dialectic, however, somewhat obscures the role Molyneux's problem has (...) played in spawning debates within the empiricist tradition. Fortunately, the differences between various empiricist accounts have been widely recognized and discussed among historians of philosophy working on the topic. The focus of the present essay is to develop an interpretation of John Locke's views on Molyneux's problem that best coheres with his other views on human understanding as well as with the predominant scientific opinion about the nature of perception during the period in which he lived.

Philosophers have often claimed that general ideas or representations have their origin in abstraction, but it remains unclear exactly what abstraction as a psychological process consists in. We argue that the Lockean aspiration of using abstraction to explain the origins of all general representations cannot work and that at least some general representations have to be innate. We then offer an explicit framework for understanding abstraction, one that treats abstraction as a computational process that operates over an innate quality space (...) of fine-grained general representations. We argue that this framework has important philosophical implications for the nativism-empiricism dispute, for questions about the acquisition of unstructured representations, and for questions about the relation between human and animal minds.

This book explores Hume's account of reason and its role in human understanding, seen in the context of other notable accounts by philosophers of the early modern period. David Owen offers new interpretations of many of Hume's most famous arguments about induction, belief, scepticism, the passions, and moral distinctions.

The primary aim of this essay is to explain the central elements of Locke's theory of knowledge. A secondary aim arises from the official definition of knowledge introduced in the opening lines of book IV. Though Locke's repeated statements of the definition are consistent with the initial formulation, the consensus view among commentators is that that official definition is in tension with other book IV doctrines. My broader interpretation involves an effort to render the various doctrines consistent with the official (...) definition. The order of discussion: Section 1 explicates the definition of knowledge. Section 2 explains two main divisions of knowledge – namely, its three degrees, and the four sorts of knowable truths. In Section 3, I consider whether Locke understands knowable truths on a model of analyticity. Section 4 addresses potential problems about the objectivity of knowledge, given Locke's account. Section 5 focuses on external world knowledge – Locke calls this "sensitive knowledge" and it poses special difficulties for the official definition of knowledge. (shrink)

Locke asserts that “the Ideas of primary Qualities of Bodies, are Resemblances of them, and their Patterns do really exist in the Bodies themselves; But the Ideas, produced in us by these Secondary Qualities, have no resemblance of them at all.”1 On an unsophisticated way of taking his words, he means that ideas of primary qualities are like the qualities they represent and ideas of secondary qualities are unlike the qualities they represent.2 I will show that if we take his (...) assertions in this unsophisticated way, our reward will be a straightforward and satisfying interpretation of the central arguments of his chapter on primary and secondary qualities. With these arguments, Locke attempts to justify his assertions about resemblance. Some may be skeptical, thinking that the assertions, interpreted literally, are either too absurd or too obvious to have reasons supporting them. I take this skepticism to rest on deep foundations of charity, so half of the paper will be devoted to undermining these foundations by giving a sympathetic and historical exposition of Locke’s positive thesis that primary qualities resemble the ideas that represent them. I criticize rival interpretations of Lockean resemblance, say what it means to believe that ideas resemble qualities, explain the plausibility of the belief in Locke’s environment, and examine his descriptions of how ideas resemble particular primary qualities. Once I establish that we should take Locke’s resemblance theses literally, I can describe their place in his theory of representation. After that, I can describe his reasons for believing the resemblance theses. I will conclude by showing how Locke’s belief that ideas of secondary qualities do not resemble anything in bodies leads him to conclude that secondary qualities are merely powers to produce ideas. Let me begin near the end, however. Before defending a literal interpretation of the resemblance theses, I want to criticize three rival interpretations.. (shrink)

The purpose of this book is to develop a terminological structure in which private perceptions can be discussed publicly without bringing into existence the usual unnecessary philosophical problems of confused usage of language. chisholm displays an appraisive, quasi-ethical use of language, whereby he claims that a thing has some particular sensible property is to have adequate evidence that it actually does have that property.

David Hume wrote that Berkeley's arguments `admit of no answer but produce no conviction'. This book aims at the kind of understanding of Berkeley's philosophy that comes from seeing how we ourselves might be brought to embrace it. Berkeley held that matter does not exist, and that the sensations we take to be caused by an indifferent and independent world are instead caused directly by God. Nature becomes a text, with no existence apart from the spirits who transmit and receive (...) it. Kenneth P. Winkler presents these conclusions as natural consequences of Berkeley's reflections on such topics as representation, abstraction, necessary truth, and cause and effect. In the closing chapters Proefssor Winkler offers new interpretations of Berkeley's view on unperceived objects, corpuscularian science, and our knowledge of God and other minds. (shrink)

Annotation In this book Mr. Mackie selects for critical discussion six related topic which are prominent in John Locke's Essay concerning Human Understanding: ...

This book is a general introduction to the philosophy of John Locke, one of the most influential thinkers in modern times. Nicholas Jolley aims to show the fundamental unity of Locke's thought in his masterpiece, the Essay Concerning Human Understanding. In this work Locke advances a coherent theory of knowledge; as against Descartes he argues that knowledge is possible to the extent that it concerns essences which are constructions of the human mind.

While claiming to refute locke's theory of abstract ideas, Berkeley himself accepts a form of abstractionism. Locke's account of abstraction is indeterminate between two doctrines: 1) abstract ideas are representations of paradigm instances of kinds, 2) abstract ideas are schematic representations of the defining features of kinds. Berkeley's arguments are directed exclusively against 2, And refute only a specific version of it, Which there is no reason to ascribe to locke; berkeley himself accepts abstract ideas of the former type. Locke's (...) theory suffers from circularity and redundancy, Berkeley's from conflation of thought with imagination. (shrink)

What philosophical issue or issues does Molyneux’s question raise? I concentrate on two. First, are there any properties represented in both touch and vision? Second, for any such common perceptible, is it represented in the same way in each, so that the two senses support a single concept of that property? I show that there is space for a second issue here, describe its precise relations to Molyneux’s question, and argue for its philosophical significance. I close by arguing that Gareth (...) Evans conflated the two issues, and thereby provide further grounds for distinguishing them. (shrink)

Locke defines knowledge as the perception of the agreement or disagreement of ideas. Nevertheless, he claims that we know particular things: the identity of our ideas, our own existence, and the existence of external objects. Although much has been done to reconcile the definition of knowledge with our knowledge of external objects, there is virtually nothing in the scholarship when it comes to knowing ideas or our own existence. I fill in this gap by arguing that perceptions of ideas are (...) complex mental states that convey propositional knowledge due to agreeing elements therein. (shrink)

This new introduction to the main themes of Berkeley′s philosophy assumes no previous knowlege of philosophy and will be accessible to first-year students and to the interested general reader. It also offers and defends its own interpretation of Berkeley′ position. Jonathan Dancy argues that we understand Berkeley′s idealism best if we take seriously his claim that realism (the view that material things have an existence independent of the mind) derives from a mistaken use of abstraction. Stress is laid on Berkelye′s (...) determination to use idealism to bring his God as close to us as possible. Instances of this are his claims that the world we live in is a collection of ideas in God′s mind, and that natural events are divine utterances which science is the attempts to interpret. Dancy also discusses Berkelye′s attack on the distinction between primary and secondary qualities, and his views on perception and knowledge. There is an account of his theory of the mind and of the nature of human action, and a final chapter contrasts the interpretation offered here with others. Students who have read this book will be well equipped to understand and assess the frequent references to Berkeley in current literature. (shrink)

John Locke is the greatest English philosopher. _An Essay Concerning Human Understanding_, one of the most influential books in the history of thought, is his greatest work. In this study the historical meaning and philosophical significance of Locke's _Essay_ are investigated more comprehensively than ever before. _Locke_ was originally published in two volumes, _Epistemology_ and _Ontology_. This paperback edition has within its covers the full text of both volumes.

If a man born blind were to gain his sight in later life would he be able to identify the objects he saw around him? Would he recognise a cube and a globe on the basis of his earlier tactile experiences alone? This was William Molyneux's famous question to John Locke and it was much discussed by English and French empiricists in the eighteenth century as part of the controversy over innatism and abstract ideas. Dr Morgan examines the whole history (...) of this debate: Locke's own (negative) answer to the question, the contributions of Berkeley, Condillac, Diderot and Voltaire and the factual accounts of early cataract operations and modern laboratory studies. He shows how this debate is involved in the development and eventual separation of philosophy and experimental psychology after the eighteenth century and considers why the original question is effectively still unanswered. This is one problem-area with its intricate cluster of connected conceptual and technical difficulties which suggests the need for some reunion or at least collaboration between the two subjects.

1. Causal knowledge is an indispensable element in science. Causal assertions are embedded in both the results and the procedures of scientific investigation. 2. It is therefore worthwhile to investigate the meaning of causal statements and the ways in which we can arrive at causal knowledge.

Laura Berchielli - Color, Space and Figure in Locke: An Interpretation of the Molyneux Problem - Journal of the History of Philosophy 40:1 Journal of the History of Philosophy 40.1 47-65 Color, Space, and Figure in Locke: An Interpretation of the Molyneux Problem Laura Berchielli THIS IS HOW LOCKE, in the second edition of his Essay Concerning Human Understanding , introduces a question that had been suggested to him in a letter from William Molyneux: . . . I shall here (...) insert a Problem of that very Ingenious and Studious promoter of Knowledge, the Learned and Worthy Mr. Molineux, which he was pleased to send me in a Letter some Months since; and it is this: Suppose a Man born blind, and now adult, and taught by his touch to distinguish between a Cube, and a Sphere of the same metal, and nighly of the same bigness, so as to tell, when he felt one and t'other, which is the Cube, which the Sphere. Suppose then the Cube and Sphere placed on a Table, and the Blind Man to be made to see. Quaere, Whether by his Sight, before he touch'd them, he could now distinguish, and tell, which is the Globe, which the Cube. In the standard interpretation of the Molyneux problem as presented in Locke, the question is always linked to the general issue of differences in the ideas of figure received by the various senses. This interpretation -- put forward by Berkeley --says that for Locke, the ideas of figure produced by sight are specifically different from.. (shrink)

Shelley Weinberg argues that the idea of consciousness as a form of non-evaluative self-awareness helps solve some of the thorniest issues in Locke's philosophy: in his philosophical psychology, and his theories of knowledge, personal identity, and moral agency. The model of consciousness set forth here binds these key issues with a common thread.
