A laboratory-testable, solid-state Maxwell demon is proposed that utilizes the electric field energy of an open-gap p-n junction. Numerical results from a commercial semiconductor device simulator (Silvaco International–Atlas) verify primary results from a 1-D analytic model. Present day fabrication techniques appear adequate for laboratory tests of principle.

The average, general readings in philosophy anthology have five to seven readings on necessary truth. This volume has fourteen. The old workhorses are here: Kant on synthetic and analytic propositions, Mill on necessary truths, Ayer on the a priori, Quine, Grice, and Strawson on dogmas of empiricism. In addition, Pap has two items, one in the middle of an exchange with Putnam over reds, greens, and the synthetic a priori. There is a tough logical analysis by Hintikka, contributions by (...) Jonathan Bennett and Hanson, and a final exchange between Katz and Quine. The selections are by no means comprehensive, but, as the editors note, this would have been impossible. A seventeen-page bibliography comes closer to fulfilling the completeness criterion. The editors include a short introduction, which really should have been expanded, since it raises some of the ontological issues that implicitly guide the debate that takes place among the selections.--E.

Three of the ten, previously unpublished papers in this volume deal with problems relating to causation. The most intriguing of these is the lead paper, in one of the symposia, by Zeno Vendler. In character with his name, Vendler argues, on the basis of some fairly gymnastic grammatical transformations and his "linguistic intuitions" that causes do not really have effects, but rather, results, which are to be distinguished categorically from the former—a thesis which might well serve as a prolegomenon to (...) an event ontology. S. Bromberger and W. H. Dray comment, Dray presenting the most important dissent on the basis that Vendler's analysis rules out agents being causes. Other papers include an analysis, by J. R. Lucas of the role of necessary and sufficient conditions in causal discourse, and an exceptionally clear presentation of a basically inductive theory of counterfactuals by J. L. Mackie. "Propositions," "Some Paradoxes," "Nonentities," and "Some Remarks about the Senses" are contributed by R. Cartwright, J. F. Thomson, A. N. Prior, and H. P. Grice respectively. D. Gasking and M. E. Lean contribute to a symposium on "Avowals," R. C. Buck's "Non-Other Minds" treats essentially the same problem, while Putnam's paper on "Dreaming and 'Depth Grammar'" serves as a highly critical review of Malcolm's Dreaming while at the same time offering a sketch of a program for linguistics.—E. A. R. (shrink)

In general, the eleven, previously unpublished papers are not as strong as those in the first series. Bromberger attempts to detail the necessary and sufficient conditions for something's being an explanation; Anscombe offers some provocative but inconclusive remarks on the intentionality of sensation; Malpas examines some criteriological puzzles which arise in considering the location of sound as a bit of unlearned perceptual behavior. The rest of the papers are second order assessments and attacks upon positions maintained by other analytical philosophers. (...) Of these Putnam's attack on Malcolm's brand of behaviorism and Butler's attempted dissolution of Goodman's "grue" paradox make their points most effectively. Moravcsik contends, against Strawson, that events are at least as primitive in our conceptual scheme as physical bodies. Wiggins questions some Fregean analyses of the logic of identity-statements; taking off from Strawson, Woods distinguishes a principle of individuation from a criterion of identity and attempts to clarify their separate but related roles by an analysis of the sorts of questions that require their use in giving answers. Rundle is concerned to modify certain Quinean answers to paradoxes of tense requirements that arise in the quantification of modal statements; Savan questions Vlastos' ascription of fallacies to the Socratic argument on the unity of Wisdom and Temperance in the Protagoras. Finally, Shorter points out the general inconclusiveness of "transformational analysis" by exhibiting specific shortcomings of Vendler's analysis of causality in the first volume of this series.—E.

Dedicated to Philipp Frank and containing introductory greetings to Frank by some of his more illustrious pupils and colleagues, the essays in this volume cover the proceedings of the Boston Colloquium for the Philosophy of Science, 1962-1964. The essays deal with most of the important problems in the philosophy of science from physics to the biological sciences and psychology, and include approaches from diverse traditions: Whiteheadian, Scientific Realism, Thomistic, Phenomenological, as well as historical approaches. High points were McMullin's "From Matter (...) to Mass," which contained a highly sensitive analysis of the Aristotelian doctrine of prime matter; Sellars's "The Identity Approach to the Mind-Body Problem"; Capek's "The Myth of Frozen Passage," which very ably took to task some historical and theoretical overextensions of Relativity Theory and spatializations of time which have resulted in the Block-Universe theory: the fact that Donald Williams commented on Capek's paper made it all the more interesting as it was William's theory in particular that was under attack. The best part of the book, however, was an approximately one hundred page exchange on the nature of scientific explanation which included a lead paper by J. J. C. Smart and lengthy commentaries by Sellars, Putnam, and Feyerabend. The issue, in part, was the radical-replaceability-of-frameworks theory of Feyerabend versus the gradual-replacement theory of Sellars.—E. A. R. (shrink)

This volume contains papers from a 1962 Symposium in the Philosophy of Mind held at Wayne State University. There are seven essays, each accompanied by lengthy and usually quite astute comments, and followed by a shorter rejoinder. Chisholm contributes a refinement of his much discussed criteria for intentional connectives: "On Some Psychological Concepts and the 'Logic' of Intentionality." The scare quotes are well-placed around "Logic," as it is Chisholm's intuitive rather than formal logical perspicacity which carries the weight of the (...) argument. Ayer's paper, "The Concept of a Person," has already been published in his book of the same name. The most deliberate exercise in epistemic logic is Castañeda's paper, "Consciousness and Behavior: Their Basic Connections." This essay deserves close scrutiny, as it represents a disciplined attempt to rehabilitate more traditional conceptions of consciousness and, particularly, self-consciousness. Putnam has some more to say about minds and machines in "The Mental Life of Some Machines." In what is possibly the best paper in the volume, Sellars develops the dialectic that runs from phenomenalism, through various forms of realism, to a critical scientific realism mediated by a Kantian-style phenomenalism. Aune's comments on the paper are very illuminating. Alston, owing to the delay in publication of the Symposium, joins a bit late the list of those who are criticizing and rejecting the logical barrier between reasons and causes that has been erected by Melden et al. Finally, Firth tries to delimit our concept of seeing by arguing in a manner more suggestive than definitive for causal criteria for the use of the term. The general tone of the volume is exploratory.—E. A. R. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:BOOK REVIEWS 389 From the perspective of this reviewer, the presently most obvious fault in this lecture lies in Putnam's criticisms of "the coherence theorists, Ludwig, et al." (p. 97). In this criticism, it is apparently assumed that the adequacy of their proposed solution to the problem considered must be judged solely on the basis of what is presently known. Since Putnam himself acknowledges that no satisfactory (...) interpretation of quantum mechanics exists, this seems unwarranted. The superficiality of the criticism of this position makes this particularly notable. He states, for example, "to say that a wave gives an incomplete description of the state of a system is to say that systems whose state can be described by that wave function may really be in several quite different physical conditions." He then adopts the doubtful strategy of appealing to the meaning of completeness and incompleteness (they are not a matter of degree) in justification of the position that it is improper to say that a wave gives an incomplete descriptionl Despite the fact that, taken as a whole, his brief criticism of the coherence theory is somewhat ungracious. Putnam has set forth the principle issues sur~ rounding the problem with discerning lucidity. Paul K. Feyerabend, in "Problems of Empiricism," places a revisionist's version of empiricism in a carefully developed historical perspective. Empiricism as it has been known is both incomplete and weakened by undesirable assumptions. The incompleteness is to be removed by regarding empiricism as a cosmological hypothesis concerning the relation between man and the universe. The version of empiricism thus admitted has the character of a scientific theory. The undesirable assumptions are views no longer tenable of the nature and content of what is given in sense. Feyerbend understands sensations and perceptions as indicators on a par with indications of physical instruments, and likewise in need of interpretation. A philosophical method is proposed which requires theoretical pluralism instead of the theoretical monism that is (inappropriately) the ideal of much of contemporary empiricism (p. 149). The function of theoretical alternatives is to provide the means of criticizing accepted theory, to which he accords careful historical treatment. "Low level theories" are to guide us to crucial experiments, while "high level theories" are to represent the basic element of the universe. Here again the reader will find a theme which emerges erpeatedly in these lectures. This theme might be stated as follows. Both macrocosmic and microcosmic systems must ultimately be involved in scientific explanation. The crucial problem that emerges is how these two are to be related or in some degree integrated. By the way in which he develops the role of alternative theories, Feyerabend has affirmed one of the principle theoretical components of what Hegel was minded to call metaphysics. An additional observation, for which what I have said should furnish some justification: Many points made throughout this exposition (115 pp. in length) might properly be regarded as together constituting a rapprochement of empiricism and rationalism. It may very well occur to the thoughtful reader that Feyerabend, in his reconstruction of empiricism, has come very near to conceding all that a critical rationalist could ask. Other lectures included in the book are, "The Thermodynamics of Purpose," by David Hawkins, "The Physics of the Large," by Philip Morrison, and "The Ethical Dimension of Scientific Research," by Nicholas Rescher. In the last-mentioned lecture, Professor Rescher points up some generally little understood ethical problems confronted by the scientist in the practice of his profession. DARREL E.

What is it to be a woman? What is it to be a man? We start by laying out desiderata for an analysis of 'woman' and 'man': descriptively, it should link these gender categories to sex biology without reducing them to sex biology, and politically, it should help us explain and combat traditional sexism while also allowing us to make sense of the activist view that gendering should be consensual. Using a Putnam-style 'Twin Earth' example, we argue that none (...) of the existing analyses in the feminist literature succeeds in meeting all of our desiderata. Finally, we propose a positive account that we believe can satisfy all the desiderata outlined. According to our theory, the genders 'woman' and 'man' are individuated not by their contemporary connections to sex biology, but by their historical continuity with classes that were originally closely connected to sex biology.

I investigate the consequences of Nietzsche's perspectivism for notions of truth and objectivity, and show how the metaphor of visual perspective motivates an epistemology that avoids self-referential difficulties. Perspectivism's claim that every view is only one view, applied to itself, is often supposed to preclude the perspectivist's ability to offer reasons for her epistemology. Nietzsche's arguments for perspectivism depend on “internal reasons”, which have force not only in their own perspective, but also within the standards of alternative perspectives. Internal reasons (...) allow a perspectivist argument against dogmatism without presupposing aperspectival criteria for theory choice. Nietzsche also offers “internal” conceptions of truth and objectivity which reduce them to a matter of meeting our epistemic standards. This view has pluralistic implications, which conflict with common sense, but it is nevertheless consistent and plausible. Nietzsche's position is similar to Putnam's recent internalism, and this is due to their common Kantian heritage. (shrink)

L’idea che vi sia una netta dicotomia tra fatti e valori è uno dei dogmi dell’empirismo. Secondo questa concezione, i giudizi fattuali, in quanto verificabili o falsificabili empiricamente, riguardano le aree di razionalità «pura» e omogenea e sono ancorati naturalisticamente al mondo. Gli enunciati di valore, invece, sarebbero da relegare nella sfera di ciò che è semplicemente «soggettivo», emotivo, irrazionale. Questo assunto, che ha dominato per molto tempo le scienze e la filosofia, è stato messo in dubbio dai pragmatisti e (...) da alcuni dei più influenti pensatori contemporanei, che, intervenendo al dibattito sull’oggettività dell’etica, hanno mostrato come la presunta eterogeneità tra giudizi descrittivi e giudizi valutativi sia ormai insostenibile. Sulla scia della prospettiva inaugurata da questi pensatori, gli autori di questo libro mostrano come la dicotomia fatto/valore abbia corrotto il nostro pensiero, impedendoci di rivolgere l’attenzione alle intersezioni, le sinergie e le relazioni che esistono tra processi cognitivi e coefficienti valutativi, tra scienza e etica.

In this systematic introduction to the philosophy of Charles S. Peirce, the author focuses on four of Peirce's fundamental conceptions: pragmatism and Peirce's development of it into what he called 'pragmaticism'; his theory of signs; his phenomenology; and his theory that continuity is of prime importance for philosophy. He argues that at the centre of Peirce's philosophical project is a unique form of metaphysical realism, whereby continuity and evolutionary change are both necessary for our understanding of experience. In his final (...) chapter Professor Hausman applies this version of realism to contemporary controversies between anti-realists and anti-idealists. Peirce's views are compared to those of such contemporary figures as Davidson, Putnam, and Rorty. The book will be of particular interest to philosophers concerned with American philosophy and current debates on realism as well as linguists working in semiotics. (shrink)

A general consensus has emerged among twentieth-century commentators on the Aeneid that pater ipse…superum must be taken together and understood as referring to the father of the gods and not to Mars, sire of Romulus. What remains a subject of debate is the meaning of honor here and its particular association with Jupiter. Does it betoken the abstraction itself or a concrete manifestation of it? Austin, following Donatus, opts for the former alternative , Norden and R. D. Williams for the (...) latter. Of these the first finds a reference to the Zeus-given sceptre of kings, the second to Jove's thunderbolt. The language of the passage argues in favour of metonymy for two reasons. First, we expect Anchises, when showing off Romulus, to adhere to the pattern he has already set in the two portions of his parade which have preceded. In the case of the initial hero, Silvius, we attend largely to genealogical background . The second segment, a group made up of Procas, Capys, Numitor and Aeneas Silvius, elicits from Aeneas' father a series of exclamations on the valour of their res gestae . Yet each also has a tangible symbol of martial virtus that distinguishes him. (shrink)

Recently, macroscopic accounts of chemical kind individuation have been proposed as alternatives to the microstructural essentialist account advocated by Kripke, Putnam, and others. These accounts argue that individuation of chemical kinds is based on macroscopic criteria such as reactivity or thermodynamics, and they challenge the essentialism that grounds the Kripke-Putnam view. Using a variety of chemical examples, I argue that microstructure grounds these macroscopic accounts, but that this grounding need not imply essentialism. Instead, kinds are individuated on the (...) basis of similarity of reactivity between substances, and microstructure explains similarity of reactivity. (shrink)

Peter Abelard (1079–1142 ce) was the most wide‐ranging philosopher of the twelfth century. He quickly established himself as a leading teacher of logic in and near Paris shortly after 1100. After his affair with Heloise, and his subsequent castration, Abelard became a monk, but he returned to teaching in the Paris schools until 1140, when his work was condemned by a Church Council at Sens. His logical writings were based around discussion of the “Old Logic”: Porphyry's Isagoge, aristotle'S Categories and (...) On Interpretation and boethius'S textbook on topical inference. They comprise a freestanding Dialectica (“Logic”; probably c.1116), a set of commentaries (known as the Logica [Ingredientibus], c. 1119) and a later (c. 1125) commentary on the Isagoge (Logica Nostrorum Petititoni Sociorum or Glossulae). In a work Abelard called his Theologia, issued in three main versions (between 1120 and c.1134), he attempted a logical analysis of trinitarian relations and explored the philosophical problems surrounding God's claims to omnipotence and omniscience. The Collationes (“Debates,” also known as “Dialogue between a Christian, a Philosopher and a Jew”; probably c.1130) present a rational investigation into the nature of the highest good, in which the Christian and the Philosopher (who seems to be modeled on a philosopher of pagan antiquity) are remarkably in agreement. The unfinished Scito teipsum (“Know thyself,” also known as the “Ethics”; c.1138) analyses moral action. (shrink)

I try to show that there is much sap (synthetic a priori) knowledge although one may not find many, or even any, sap true statements in most natural languages. Reasons are given for the difficulty of expressing sap truths in natural languages, but it is argued that these are not necessary features of language as such. There are, then, sap true statements in some possible languages.Admission of the sap gives one a way of distinguishing logical from metaphysical possiblity. Something is (...) metaphysically impossible just in case it is a sap truth that it is impossible. I argue that the realm of logically possible entities is vastly larger than the realm of metaphysically possible entities.My.defence of the sap begins with a partial defence of the analytic/synthetic distinction. In particular, I attack the intentionality circle argument,Quine's indeterminacy thesis and some applications of the Kripke/Putnam theory of meaning for natural kind terms. Without being a conclusive defence of the analytic/synthetic distinction, this section makes the defence of the sap more secure. Arguments are then mounted in direct defence of the sap by showing that the purported reduction of sap truths to analytic truths is mistaken. Examples are adduced to show that, even where expressions of natural language fail, one can stipulate usage in ways that allow expression of sap truths. I then consider and reply to various objections, giving an example of the sort of meaning theory which illegitimately legislates the analyticity of any purported sap true statement. (shrink)

In this article the contemporary debate between realism and anti-realism in analytical philosophy is analysed and discussed. It is claimed that the nature of the reference relation which holds between language and the world is central in this discussion which has both logical, semantical, and epistemological aspects. In a first part A. Tarski's (semantic) theory of thru th is explained and it is shown how, amongst several theories of truth, Tarski's may be called a realist one. However, a Tarski-style semantics (...) need not lead to a realist theory of Truth and Reference, as is shown in a subsequent part. Here H. Putnam's views on these matters are discussed. It is shown how Putnam in the course of his intellectual history has changed his view from a realist to an anti-realist position. Putnam's arguments show the importance of logical and metalogical issues in the debate. In a final part Putnam's views are criticized and it is shown how a line of argument, analogous to Putnam's, may lead to a realist theory of meaning and reference. (shrink)

In the discussion between realism and anti-realism, the causal theory of reference plays a central role. As a version of metaphysical realism, causal realism maintains that language is hooked upon the world by means of causal chains that account for the relation between language and extra-linguistic reality, a thesis denied by antirealism in its various forms. The paper investigates these criticisms which are both logical and epistemological, taking as an example H. Putnam's views on these matters. It is argued (...) that the anti-realist criticisms against the causal theory of reference may at least in part be misdirected, since they use a concept of causality that is of a qualitatively different nature from the one used in realist theories. Finally, it is shown how the main tenets of metaphysical realism can be reformulated so as to accomodate for several more general—but related—criticisms having to do with its ontological and epistemological presuppositions.

One problem with assessing quantum logic is that there are considerable differences between its practitioners. In particular they offer different versions of the set of sentences which the logic governs. On some accounts the sentences involved describe events, on others they are ascriptions of properties. In this paper a framework is offered within which to discuss different quantum logical interpretations of quantum theory, and then the works of Jauch, Putnam, van Fraassen and Kochen are located within it.

In lieu of an abstract, here is a brief excerpt of the content:Philosophy, Psychiatry, & Psychology 12.4 (2005) 325-329 [Access article in PDF] Psychoanalysis as Natural Philosophy R. D. Hinshelwood Keywords evolution, psychopathology, ethics, unconscious phantasy Andreas De Block has offered us a most fascinating paper. We do not have to agree with all his points to be profoundly stimulated by them. His core proposition is that Freud pathologizes ordinary psychology and personalities, as well as the abnormal. There has been (...) a perennial debate about whether, psychoanalytically speaking, there is a continuum from pathology to normality or if there is a discontinuity at some point between the two. Freud's famous quote—"much will be gained if we succeed in transforming your hysterical misery into common unhappiness" (Breuer and Freud 1895, 305)—is ambiguous. Interestingly, De Block takes a hard stand on this; he not only assumes a continuum, but further he reads Freud as saying that all normality is neurotic. This is not a usual reading of Freud. De Block then expands this into a philosophical position. It is, he says, Freud's philosophy on the nature of mind.Freud himself was not interested in philosophy, and thought it largely irrelevant to psychoanalysis. In fact, he mused about the traffic being inevitably in the opposite direction—that philosophy might come to psychoanalysis. In discussing the work of a philosophically inclined analyst, he remarked, The decisive reason for the rejection of Putnam's proposals was the doubt as to which of the countless philosophical systems should be accepted, since they all seem to rest on an equally insecure basis.... It seemed more prudent to wait, and to discover whether a particular attitude towards life might be forced upon us with all the weight of necessity by analytical investigation itself. (Freud 1921, 270) Psychoanalysis, Freud thought, might be the very substance from which a philosophical system could emerge. De Block has followed that route; he has gone to Freud's writing to discovery a weltanshaung on which we might develop a philosophy of life. He has come back from his intellectual expedition with Freud's fascinating paper, published only in 1987 (discovered in 1983), "A Phylogenetic Phantasy." This was actually written in 1914, but Freud never published it and in fact destroyed his own copy of the draft. The paper has been called a "metabiology" (Gubrich-Simitis 1987), and deals with Freud's speculation on how a threatened species during the ice age developed certain biological and biopsychological traits1 necessary to survive the harsh environmental conditions. These traxits, which included the repression of libido, had significant side effects, namely, the pathologies arising from repression: the neuroses, perversions and psychoses. Moreover, today the environmental conditions no longer apply, so we are left with the side effects of traits that are no longer biologically useful. [End Page 325]So, De Block indicates at least the possibility of an evolutionary theory of the nature of mind. Even if Freud's Lamarckianism makes his particular speculative metabiology implausible, it is a way of thinking that suggests that a theory of mind can arise from biological understanding of its evolutionary development. However, De Block goes further. As a corollary, because Freud's view of the evolution of mind is to involve the evolutionary nature of psychopathology, then Freud's psychoanalysis can suggest an evolutionary psychiatry—that is to say, psychiatry can look for distant causes of mental disturbance in the vagaries of evolutionary influence.This way of approaching philosophy is interesting because it starts with the outcome of a scientific investigation of the human mind, just as Freud suggested in the passage quoted (Freud 1921, 270). The prospect is for a natural philosophy of mind, just as the physics of fundamental particles and the "big bang" prompt us toward a kind of natural ontology of the universe and its contents, arising from empirically tested facts.However, De Block is on rather uncertain ground with the evidence for his argument; he commits Freud to this biological speculation on the basis of a paper that Freud did not in fact publish and tore up.2 Even if Freud's reading of the evolutionary origins of man...

The Quine/Putnam indispensability argument is regarded by many as the chief argument for the existence of platonic objects. We argue that this argument cannot establish what its proponents intend. The form of our argument is simple. Suppose indispensability to science is the only good reason for believing in the existence of platonic objects. Either the dispensability of mathematical objects to science can be demonstrated and, hence, there is no good reason for believing in the existence of platonic objects, or (...) their dispensability cannot be demonstrated and, hence, there is no good reason for believing in the existence of mathematical objects which are genuinely platonic. Therefore, indispensability, whether true or false, does not support platonism. (shrink)

In his review of our Gödel's Proof in the April 1960 issue of Philosophy of Science Professor Hilary Putnam severely criticizes the crucial chapter, in which we attempt to make intelligible to the non-specialist the general character of the argument for Gödel's main conclusions. Indeed, he asserts that “the chapter culminates in an extremely serious misstatement,” and that we “fail to give the proof that G [the Gödel sentence upon which the argument hinges] is not provable.” “The book,” he (...) declares, “has thus a serious shortcoming ”. These assertions impugn the competence of our exposition of Gödel's achievements, and we therefore ask for the privilege of replying to Dr. Putnam's allegations. (shrink)

Putnam and Finkelstein have proposed the abandonment of distributivity in the logic of quantum theory. This change results from defining the connectives, not truth-functionally, but in terms of a certain empirical ordering of propositions. Putnam has argued that the use of this ordering ("implication") to govern proofs resolves certain paradoxes. But his resolutions are faulty; and in any case, the paradoxes may be resolved with no changes in logic. There is therefore no reason to regard the partially ordered (...) set of propositions as a logic--i.e. as embodying a criterion for soundness of proofs. Its role in quantum theory ought to be understood in an entirely different way. (shrink)

A critique of LaPorte's views on chemical kinds, like jade and ruby, is presented. More positively, a new slant is provided on the question of whether elements are natural kinds. This is carried out by appeal to the dual nature of elements, a topic that has been debated in the philosophy of chemistry but not in the natural kinds literature. It is claimed that the abstract notion of elements, as opposed to their being simple substances, is relevant to the Kripke– (...) class='Hi'>Putnam approach to natural kinds and to some criticisms that have been raised against it, although I do not support the K–P account. The proposed view avoids the traditional microstructuralist approach to natural kinds. The article also addresses the question of whether natural kinds concern metaphysical or epistemological considerations. Recent attempts by chemists to modify the periodic table are brought to bear on the question of classification and consequently on whether the identification of elements is interest dependent.

As Max Jammer has rightly said, contemporary discussion of the metrical properties of space have been dominated in recent years by the work of Adolf Grünbaum. One of Grünbaum's most important essays in this area, "Geometry, Chronometry and Empiricism" is reprinted in its entirety as the first chapter of this work. The third and final chapter is a lengthy reply to Hilary Putnam who published a critique of Grünbaum's original essay in 1963. Putnam's criticisms have not led Grünbaum (...) to substantially change his views but they have provided the means for some clarification and extension of those views, e.g., with respect to the notions of congruence and conventionality and in relation to Zeno's paradoxes, color attributes, and other topics. Between the original essay and the lengthy reply to Putnam there is a shorter chapter which deals with, among other things, the hypothesis that everything has doubled overnight, a related topic to which Grünbaum has given some attention in journal articles. It is safe to say that persons concerned with the problem of conventionalism and other philosophical problems about space will have to work their way through this important book.--R. H. K. (shrink)

This article seeks to present a detailed textual analysis of Protagoras’ Great Speech in Plato's Protagoras. I will argue that the concept of ἀρετή as it appears in the Great Speech is whittled down to a vague notion of civic duty. In this respect, Protagoras is bringing himself in line with the democracy, but in doing so the ἀρετή he claims to teach loses much of its initial appeal, particularly in the eyes of his aristocratic clientele. Nevertheless, if thecontentof Protagoras’ (...) Great Speech overlooks the abilities required to rise to political prominence, theformmost assuredly does not. As one would expect from Plato's Protagoras, his speech is replete with just that oratorical prowess his students might expect to acquire from him. This, in turn, has a number of interesting and important implications in the broader context of theProtagoras, in particular regarding the contrast or conflict between long speeches and short-answer dialectic. Moreover, although it has long been noticed that Protagoras neglects rhetoric and personal pre-eminence in his account, as far as I know there has not been any serious attempt to analyse the stylistic aspects of this masterful speech. Accordingly, both this and my attempt to interpret it within the economy of the dialogue are original. (shrink)

Kant’s and Hegel’s transcendental argument for mental-content externalism breaks the deadlock between ‘internal’ and genuine realists. This argument shows that human beings can only be self-conscious in a world that provides a humanly recognizable regularity and variety among the things (or events) we sense. This feature of the world cannot result from human thought or language. Hence semantic arguments against realism can only be developed if realism about the world is true. Some of Putnam’s arguments for internal realism are (...) taken as cases in point, and criticized accordingly. Pragmatic realists can use this transcendental argument, because its strong modal claims are consistent with falliblist accounts of justification. (shrink)

This fifth volume in the Boston Studies in the Philosophy of Science is devoted primarily to the natural sciences, but like previous volumes in this series there is considerable variety in the topics discussed and the approaches taken by different contributors differ markedly. The first contribution is a 150 page essay by A. Grünbaum which is a reply to Hilary Putnam's critique of Grünbaum's philosophy of geometry. The essays by Peter Havas on causality and relativity and by Carl F. (...) von Weizäcker on the unity of physics are essays on the foundations of physical science by physicists who have distinguished themselves in this area. Helpful comments are added to the Havas' paper by John Stachel and to the von Weizäcker paper by Francis Zucker. Zucker provides a useful introduction to von Weizäcker's ambitious project of unifying physics for reader's unfamiliar with von Weizäcker's work. A symposium on theoretical entities and functional explanation in biology is included, with a paper by June Goodfield and comments by Ernst Mayr and Joseph Agassi. Historical essays include a discussion of hypotheses in Newton's philosophy and the development of the cognitive faculties in the theories of Ernst Mach. In addition, there are essays on logic in relation to physical science, measurement, models, symmetry, proof, truth, and the Copenhagen interpretation of quantum theory.--R. H. K. (shrink)

As Max Jammer has rightly said, contemporary discussion of the metrical properties of space have been dominated in recent years by the work of Adolf Grünbaum. One of Grünbaum's most important essays in this area, "Geometry, Chronometry and Empiricism" is reprinted in its entirety as the first chapter of this work. The third and final chapter is a lengthy reply to Hilary Putnam who published a critique of Grünbaum's original essay in 1963. Putnam's criticisms have not led Grünbaum (...) to substantially change his views but they have provided the means for some clarification and extension of those views, e.g., with respect to the notions of congruence and conventionality and in relation to Zeno's paradoxes, color attributes, and other topics. Between the original essay and the lengthy reply to Putnam there is a shorter chapter which deals with, among other things, the hypothesis that everything has doubled overnight, a related topic to which Grünbaum has given some attention in journal articles. It is safe to say that persons concerned with the problem of conventionalism and other philosophical problems about space will have to work their way through this important book.--R. H. K. (shrink)

Adherence to a few basic principles of textbook reading compilation have made this one of the more worthwhile introductory philosophy texts. In the first place, the editors have given lengthy and frequently complete texts. Anselm's Proslogium, Descartes' Meditations, Plato's Phaedo, and Kant's Prolegomena are given complete or nearly complete; there is a ninety-one page extract from Locke's Essay, over fifty pages of James and nearly forty pages from Whitehead. This still leaves room for ample primary material by Leibniz, Hume, and (...) Schopenhauer. The plan of the book is to frame the important primary text with intellectually contemporaneous discussion of the problems treated in the primary text, and then to bracket each section with a prologue and epilogue drawn—except in the final section where Plato has the last word—from twentieth-century literature relevant to the issues under discussion in each section. The authors are thus able to provide an historical and thematic introduction to philosophy, which together cannot help but impress the beginning student with the unity of philosophical experience. Obviously no single textbook will ever escape the need for supplementation; this one in particular will require those who would like their students to be exposed to more phenomenology and existentialism, and, to a lesser degree, analytical philosophy, to introduce additional reading. But Epstein and Kennedy have provided the basic skeleton to which may be added as much flesh as the instructor desires.—E. A. R. (shrink)
