Locke claims that we have sensitive knowledge of the external world, in virtue of the fact that simple ideas are real, true, and adequate. However, despite his dismissive remarks about Cartesian external-world skepticism, Locke gives us little to go on as to how knowledge of the external world survives the fact of perceptual error, or even how perceptual error is possible. I argue that Locke has an in-principle problem explaining perceptual error.

Berkeley argues that our ideas cannot represent external objects, because only an idea can resemble an idea. But he does not offer any argument for the claim that an idea can represent only what it resembles - a premise essential to his argument. I argue that this gap can be both historically explained and filled by examining the debates between Cartesians and sceptics in the late seventeenth century. Descartes held that representation involves two relations between an idea and its object (...) ? resemblance and causation ? and that these relations are very closely linked to each other. I look at variations upon this claim in later Cartesians, especially Desgabets and Régis. I also examine the critics who attacked this claim, especially Huet, Foucher, and Du Hamel, who developed arguments similar to Berkeley's but concluded that (Cartesian) representation is simply impossible. I also argue that Malebranche, although an adherent of the Cartesian theory of intentionality, used a modified version of this argument to argue for his claim that ideas do not exist in the mind at all. These thinkers, and especially Malebranche, provide the context in which we should understand Berkeley. (shrink)

Looks at accounts by Locke, Fodor, Dretske, and Millikan concerning the nature of mental representation, and discusses connectionism and representation.

This paper argues that Locke has a representative theory of sensitive knowledge. Perceivers are immediately aware of nothing but sensory ideas in the mind; yet perceivers think of real external substances that correspond to and cause those ideas, and they are warranted in believing that those substances exist (at that time). The theory poses two questions: what warrants the truth of such beliefs? What is it in virtue of which sensory ideas represent external objects and how do they make perceivers (...) think of those objects? Both the epistemic and semantic issues need to be addressed. This paper urges that Locke's basic account of warrant is roughly reliabilist. The causal origin of sensory ideas assures that, in general, sense based beliefs are true. Locke defines the limit of this warrant by the theoretical point that we cannot discuss skeptical doubt without assuming the truthfulness of our perceptual faculty. Turning to the semantic question, the paper argues that ideas are mental modifications or entities. They are not intrinsically representative (satisfiable), but rather represent only by virtue of their causal origin. They merely “track” the presence of substances and their qualities. Ideas nevertheless prompt perceivers to think of their causes. This is roughly because sensory ideas have a specific mental role, namely, to serve as marks for distinguishing substances and their respective qualities for purposes of action. The paper suggests that, for Locke, the challenge posed by the semantic veil of ideas is to explain this externally directed marking function within bounds of his anti‐innatism. But it concludes that his answers to the twin questions fit together reasonably well. (shrink)

George Berkeley (1685-1753) is the superstar of Irish Philosophy. He entered Trinity College, Dublin, in 1700 and became a fellow in 1707. In 1724 he resigned his Fellowship to become Dean of Derry, and in 1734 he was made Bishop of Cloyne. He settled in Oxford in 1752 and died the following year. The work of George Berkeley is marked by its diversity and range. His writings take in such topics as mathematics, psychology, politics, health, economics, deism and education, as (...) well as that with which he is most associated - philosophy. Whatever topic he dealt with, his grasp of the subject matter was always impressive and his criticisms of his contemporaries often acute. Among the most noteable of the British Empiricists, he took his starting point from Locke's new 'way of ideas', but he rejected abstract ideas and the possibility of real existence outside perception. It is for this doctrine that he is most known - that there is no such thing as matter, and that things are collections of ideas which can exist only in our minds and only for so long as they are perceived. This philosophy, summed up in his phrase 'to be is to be perceived', he termed 'immaterialism'. A.C. Fraser's collection includes a series of what were previously unpublished notes by Berkeley on all the main topics of his philosophy. This, the 1901 edition, was the first complete edition of his works. (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)

The present volume has grown out of a conference organized jointly by the History of Philosophy Department of the University of Miskolc and the History and Philosophy of Science Department of Eötvös Loránd University (Budapest), which took place in June 2002. The aim of the conference was to explore the various angles from which intentionality can be studied, how it is related to other philosophical issues, and how it figures in the works of major philosophers in the past. It also (...) aimed at facilitating the interaction between the analytic and phenomenological traditions, which both regard intentionality as one of the most important problems for philosophy. Indeed intentionality has sometimes provided inspiration for works bridging the gap between the two traditions, like Roderick Chisholm’s in the sixties and Dagfin Føllesdall’s and his students’ in the early eighties. These objectives were also instrumental in the selection of the papers for this volume. Instead of very specialized papers on narrow issues, we gave preference to papers with a broader focus, which (1) juxtapose different approaches and traditions or (2) link the issues of intentionality with other philosophical concerns.

This book is available either individually, or as part of the specially-priced Arguments of the Philosphers Collection.

The paper argues for the view advocated by Yolton that Locke's ideas are best viewed as intentional contents. Drawing on Smith and McIntyre's distincition between object- and content-theories of intentionality I seek it show that it belongs to the second category. The argument relies mainly on the analysis of Locke's discussion of meaning, the reality and adequacy of ideas and real essence.
