In lieu of an abstract, here is a brief excerpt of the content:Russell's external world: 1912-1921 by Ronald E. Nusenoff IN "The Relation of Sense-data to Physics",lOur Knowledge ofthe External World,2 and "The Ultimate Constituents ofMatter",3 Russell presents a phenomenalistic reduction ofphysical objects. On this theory, the external world becomes a physical space of six dimensions, which must be logically constructed by a three-dimensional ordering of three-dimensional phenomenal spaces. In what follows, we will consider Russell's varying views, from causal (...) realism in The Problems of Philosophy,4 through phenomenalism, to neutral monism in The Analysis ofMind,5 on the nature ofthe external world. We will pay particular attention to the relation between physical and phenomenal space, and the status ofthe causal theory ofperception. 1. Realism (1912) In The Problems ofPhilosophy, Russell distinguishes a single "real" space ofscience from the "apparent" spaces ofperception. He begins with various cases of perceptual relativity, illusion, etc., and from these infers that those object which are immediately known to us are not the physical objects which the layman might take them to be. Rather, what are immediately known are sense-data, these being caused by, and so in some sense "corresponding" to, physical obI "The Relation of Sense-data to Physics", Scientia, 4 (1914), reprinted as Chapter VIII of Mysticism and Logic and Other Essays (London, 1918). 2 Our Knowledge ofthe External World as a Fieldfor Scientific Method in Philosophy (London, 1914). 3 "The Ultimate Constituents of Matter", Monist, 25 (1915), reprinted as Chapter VII of Mysticism and Logic. 4 The Problems ofPhilosophy (London, 1946 [lst published, 1912]). 5 The Analysis of Mind (London, 1921). 65 66 Russell, nos. 29-32 (1978) jects. Physical objects are located in "one public all-embracing physical space", while "our sense-data are situated in our private spaces, either the space of sight or the space of touch or such vaguer spaces as other senses may give us".6 Through experience, we are able to correlate these various private sense-data spaces (i.e., in so far as we can correlate experiences in one with experiences in another). What Russell does not go on to do here is define physical space in terms of private spaces. Given that (a) Space is relational rather than absolute, and (b) All that we can know about physical objects is that both they and their relations "correspond" to our sense-data and their relations, then (c) "we may assume that there is a physical space in which physical objects have spatial relations corresponding to those which the corresponding sense-data have in our private spaces".7 Our knowledge of physical space is then merely knowledge of relative position, and other features, e.g., shape, are "only supposed to correspond to the physical space so far as is required for the preservation of the order".8 On this view, the existence ofa physical space is necessitated solely by, and so is no more plausible than, the need for physcial objects. Russell's argument for accepting our "instinctive" belief that physical objects exist is less than compelling. Since this belief does not lead to any difficulties, but on the contrary tends to simplify and systemize our account of our experiences, there seems no good reason for rejecting it.9 In what follows, ~e shall see that Russell's phenomenalism is not explainable as differing from the realism found in The Problems of Philosophy merely in the rejection of this "instinctive" belief. II. Phenomenalism (1914-?) In his "Reply to Criticisms" in the Schilpp collection,IO Russell seems to deny that he ever really accepted phenomenalism. 6 The Problems of Philosophy, pp. 30-1 7 Ibid., p. 31. 8 Ibid., p. 33. 9Ibid., p. 24. 10"Reply to Criticisms", in P.A.

This was a technical hypothesis which I was trying to make logically adequate.

Interpretations from the past 30 years of frege's explanation of the cognitive value of identity sentences are considered. Frege's explanation, Which the author finds superior to any of these interpretations, Is that 'a=b' has greater cognitive value than 'a=a' because, Given that 'a' and 'b' are different sign-Types, The sense of 'a' "may" (though it need not) differ from that of 'b'. It is pointed out that this interpretation of frege shows that his problem with identity sentences can be resolved (...) prior to the larger problem of explicating the notion of sense. (shrink)

Elliot R. Wolfson intervenes in the debate over Martin Heidegger and Nazism from a unique perspective, as a scholar of Jewish mysticism and philosophy who has been profoundly influenced by Heidegger's work. He reveals crucial aspects of Heidegger's thinking that betray an affinity with dimensions of Jewish thought.

Children are not simply molded by the environment; through constant inference and interpretation, they actively shape their own social world. This book is about that process. Elliot Turiel's work focuses on the development of moral judgment in children and adolescents and, more generally, on their evolving understanding of the conventions of social systems. His research suggests that social judgements are ordered, systematic, subtly discriminative, and related to behavior. His theory of the ways in which children generate social knowledge through (...) their social experiences will be of interest to a wide range of researchers and students in child development and education.

No one theory of time is pursued in the essays of this volume, but a major theme that threads them together is Wolfson’s signature idea of the timeswerve as a linear circularity or a circular linearity, expressions that are meant to avoid the conventional split between the two temporal modalities of the line and the circle.

Clear and distinct perception is the centrepiece of Descartes’s philosophy — it is the source of all certainty — but what does he mean by ‘clear’ and ‘distinct’? According to the prevailing approach, what it means for a perception to be clear is that its content has a certain objective property, like truth. I argue instead that clarity is at least partly a subjective, phenomenal quality whereby a content is presented as true to the perceiving subject. Clarity comes in degrees. (...) Any weak degree of clarity, available to the senses, can be merely subjective, since what it presents as true may not actually be true. But complete clarity, available to intellectual perception, has an objective dimension, since what it presents as true is always some truth, some bit of reality. Further, I argue that the other perceptual qualities that Descartes identifies — obscurity, confusion, and distinctness — are all defined in terms of clarity. Of particular note is the fact that distinctness is not a positive feature to be added to clarity: a distinct perception is just a completely clear perception. (shrink)

This entry provides a substantive overview of research and debates concerning creativity in philosophy and related fields. Topics covered include definitions of creativity, whether creativity can be learned, whether it can be explained, attempts to explain creativity in cognitive science, and whether computer programs or AI systems can be creative.

This paper explicates Descartes’ theory of intuition (intuitus). Departing from certain commentators, I argue that intuition, for Descartes, is a form of clear and distinct intellectual perception. Because it is clear and distinct, it is indubitable, infallible, and provides a grade of certain knowledge he calls ‘cognitio’. I pay special attention to why he treats intuition as a form of perception, and what he means when he says it is ‘clear and distinct’. Finally, I situate his view in relation to (...) those of his Scholastic predecessors on one hand and current theories on the other. His view anticipates the contemporary ‘perceptual model of intuition’, though it is much bolder with its promise of certainty. (shrink)

Three kinds of things may be creative: persons, processes, and products. The standard definition of creativity, used nearly by consensus in psychological research, focuses specifically on products and says that a product is creative if and only if it is new and valuable. We argue that at least one further condition is necessary for a product to be creative: it must have been produced by the right kind of process. We argue furthermore that this point has an interesting epistemological implication: (...) when you judge a product to be creative--attributing creativity--you are not just judging it to be new and valuable. Even if you did not witness how it was produced, you are also making a judgement about how it was produced. (shrink)

Descartes is widely portrayed as the arch proponent of “the epistemological transparency of thought” (or simply, “Transparency”). The most promising version of this view—Transparency-through-Introspection—says that introspecting (i.e., inwardly attending to) a thought guarantees certain knowledge of that thought. But Descartes rejects this view and provides numerous counterexamples to it. I argue that, instead, Descartes’s theory of self-knowledge is just an application of his general theory of knowledge. According to his general theory, certain knowledge is acquired only through clear and distinct (...) intellection. Thus, in his view, certain knowledge of one’s thoughts is acquired only through clear and distinct intellection of one’s thoughts. Introspection is a form of intellection and it can be clear and distinct. Ordinarily, however, introspection isn’t clear and distinct but is instead confused with dubitable perceptions of bodies. To make introspection clear and distinct, we need to “sharply separate” it from all perceptions of bodies by doubting all perceptions of bodies. Without such radical doubt, introspection remains confused and we lack certain knowledge not just of the specific features of our thoughts, but even of the minimal claim that a thought exists. Far from being the high priest of Transparency, Descartes is radically opposed to it. (shrink)

This essay concerns two forms of moral non-naturalism according to which general moral principles or laws enter into the grounding explanations of particular moral facts. According to bridge-law non-naturalism, the laws are themselves partial grounds of the moral facts; whereas according to grounding-law non-naturalism, the laws explain the grounding connections that obtain between particular natural facts and particular moral facts. I pose and develop an objection to BLNN concerning moral worth: as compared to GLNN, BLNN has trouble accommodating the common (...) intuition that actions performed out of motivation for rightness de dicto are, at least in paradigm cases, deficient in their moral worth as compared to those performed out of motivation for rightness de re. After presenting the moral worth objection to BLNN, I respond to a possible defense of the view and explain why GLNN is not itself imperiled by an analogous objection. I finally argue that in light of the moral worth objection, a purported analogy between the law and morality fails to give us any reason to prefer BLNN to GLNN. I conclude that non-naturalists who accept the existence of general and explanatory moral principles should adopt GLNN rather than BLNN. (shrink)

In Matters of Life and Death Elliot Dorff thoroughly addresses this unavoidable confluence of medical technology and Jewish law and ethics.

In this reprint of Law's Empire,Ronald Dworkin reflects on the nature of the law, its given authority, its application in democracy, the prominent role of interpretation in judgement, and the relations of lawmakers and lawgivers to the community on whose behalf they pronounce. For that community, Law's Empire provides a judicious and coherent introduction to the place of law in our lives.Previously Published by Harper Collins. Reprinted (1998) by Hart Publishing.

Creativity pervades human life. It is the mark of individuality, the vehicle of self-expression, and the engine of progress in every human endeavor. It also raises a wealth of neglected and yet evocative philosophical questions: What is the role of consciousness in the creative process? How does the audience for a work for art influence its creation? How can creativity emerge through childhood pretending? Do great works of literature give us insight into human nature? Can a computer program really be (...) creative? How do we define creativity in the first place? Is it a virtue? What is the difference between creativity in science and art? Can creativity be taught? The new essays that comprise The Philosophy of Creativity take up these and other key questions and, in doing so, illustrate the value of interdisciplinary exchange. Written by leading philosophers and psychologists involved in studying creativity, the essays integrate philosophical insights with empirical research. CONTENTS I.

This paper provides a new solution to the problem of moral permissions for the moral error theory. The problem is that the error theorist seems committed to the claim that all actions are morally permitted, as well as to the contradictory claim that no action is morally permitted. My solution understands the moral error theory as the view that folk moral discourse is systematically in error by virtue of suffering from semantic presupposition failure, which I show is consistent with a (...) Kratzerian semantics for deontic modals in natural language. Formally, the solution is to treat the ordering source parameter within Kratzer’s semantics as undefined in the case of folk moral discourse. The paper concludes with thoughts about the import of the solution proffered for the alleged independence of the moral error theory from normative ethics. (shrink)

For the past two decades, it has widely been assumed by linguists that there is a single computational operation, Merge, which is unique to language, distinguishing it from other cognitive domains. The intention of this paper is to progress the discussion of language evolution in two ways: (i) survey what the ethological record reveals about the uniqueness of the human computational system, and (ii) explore how syntactic theories account for what ethology may determine to be human-specific. It is shown that (...) the operation Label, not Merge, constitutes the evolutionary novelty which distinguishes human language from non-human computational systems; a proposal lending weight to a Weak Continuity Hypothesis and leading to the formation of what is termed Computational Ethology. Some directions for future ethological research are suggested. (shrink)
