Jerry Fodor and Ernest Lepore [(1992) Holism: a shopper's guide, Oxford: Blackwell; (1996) in R. McCauley (Ed.) The Churchlands and their critics , Cambridge: Blackwell] have launched a powerful attack against Paul Churchland's connectionist theory of semantics--also known as state space semantics. In one part of their attack, Fodor and Lepore argue that the architectural and functional idiosyncrasies of connectionist networks preclude us from articulating a notion of conceptual similarity applicable to state space semantics. Aarre Laakso and Gary (...) class='Hi'>Cottrell [(1998) in M. A. Gernsbacher & S. Derry (Eds) Proceedings of the 20th Annual Conference of the Cognitive Science Society, Mahway, NJ: Erlbaum; Philosophical Psychology ] 13, 47-76 have recently run a number of simulations on simple feedforward networks and applied a mathematical technique for measuring conceptual similarity in the representational spaces of those networks. Laakso and Cottrell contend that their results decisively refute Fodor and Lepore's criticisms. Paul Churchland [(1998) Journal of Philosophy, 95, 5-32 ] goes further. He uses Laakso and Cottrell's neurosimulations to argue that connectionism does furnish us with all we need to construct a robust theory of semantics and a robust theory of translation. In this paper I shall argue that whereas Laakso and Cottrell's neurocomputational results may provide us with a rebuttal of Fodor and Lepore's argument, Churchland's conclusion is far too optimistic. In particular, I shall try to show that connectionist modelling does not provide any objective criterion for achieving a one-to-one accurate translational mapping across networks. (shrink)

Jerry Fodor and Ernest Lepore have launched a powerful attack against Paul Churchland's connectionist theory of semantics—aka State Space Semantics. In one part of their overall attack, they exploit the potentially orthogonal histories of different individuals to introduce what they labeled ‘the collateral information problem’. Aarre Laakso and Gary Cottrell have recently put forward a mathematical technique for measuring conceptual similarity across neural networks. Churchland uses Laakso and Cottrell's tecnique to defend State Space Semantics. In this paper (...) I shall highlight a potential problem for Laakso and Cottrell's technique, and for Churchland's subsequent defence of connectionist semantics that has been ignored in the connectionist literature. I shall argue that a connectionist sympathiser of Churchland could not make use of Laakso and Cottrell's neurosimulations to address Fodor and Lepore's collateral information challenge. (shrink)

There is much we do not know about nanotechnology. Despite its tremendous promise, nanotechnology today is mostly forecast and fervent hope. Predictions that spending on nanotechnology will increase from current levels of $13 billion to more than $1 trillion by 2015 are no more than that – simply predictions. Hopes that nanotechnology will be an essential part of solving the globe's energy, food, and water problems should be tempered by recalling a century of revolutionary technologies that failed to live up (...) to their early promise such as nuclear energy, supersonic airplanes, or gene therapy. Many other questions continue to nip at nanotechnology's heels, not the least of which are debates about what is and is not technically feasible. Despite these uncertainties, we can have complete confidence in one aspect of nanotechnology's future – it will be subject to a host of regulations. (shrink)

Is capitalist production unjust? It is easy to think, upon first reading Marx, that he answers this question in the affirmative. And I shall argue that this naive reading is correct. This needs to be argued, however, for a more careful scrutiny of Marx's writings reveals passages in which he seems to call capitalist production just or fair. Relying upon these passages, Robert Tucker and Allen W. Wood have urged that, in Wood's words,it is simply not the case that Marx's (...) condemnation of capitalism rests on some conception of justice, and those who attempt to reconstruct a “Marxian idea of justice” from Marx's manifold charges against capitalism are at best only translating Marx's critique of capitalism, or some aspect of it, into what Marx himself would have consistently regarded as a false, ideological, or “mystified” form.What Marx regarded as false and mystified, however, is not the practice of assessing social institutions as just or unjust, but rather the picture of those institutions, and especially of capitalist production, to be found in bourgeois ideology.

My concern in this paper will be to explore and develop a version of nonsocratic skepticism about weakness of will. In my view, socratism is incorrect, but like Socrates, I think that the common understanding of weakness of will raises serious problems. Contrary to socratism, it is possible for a person knowingly to act contrary to his or her better judgment. But this description does not exhaust the common view of weakness. Also implicit in this view is the belief that (...) actions which are contrary to one's better judgment are free in the sense that the agent could have done otherwise. To take seriously the possibility of acting contrary to one's better judgment is at the same time to raise problems about the distinction between weakness and compulsion. I argue that the common view, according to which the differentiating feature is that the weak are able to conform their behavior to their practical judgments, is unjustified. Instead, I have proposed that weakness of will involves the failure to develop certain normal capacities of self-control, whereas compulsion involves desires which even the possession of such capacities would not enable one to resist.

This article examines Simpson's paradox as applied to the theory of probabilites and percentages. The author discusses possible flaws in the paradox and compares it to the Sure Thing Principle, statistical inference, causal inference and probabilistic analyses of causation.

Abstract:This paper delineates the normative and empirical approaches to business ethics based upon five categories: 1) academic home; 2) language; 3) underlying assumptions; 4) theory purpose and scope; 5) theory grounds and evaluation criteria. The goal of the discussion is to increase understanding of the distinctive contributions of each approach and to encourage further dialogue about the potential for integration of the field.

In a recent Article Carla Kary attempts to show that there should be a significant moral difference between instances of killing and letting die. I shall maintain in Section I that Kary's argument is somewhat weakened by the failure to note an important ambiguity in the notion of killing a person. I shall also argue in Section II that a similar ambiguity affects the notion of letting someone die, and that the failure to note this latter ambiguity also weakens the (...) position developed by Robert Coburn with regard to defective newborns.

The late 20th century saw a remarkable flourishing of philosophy in France. The work of French philosophers is wide ranging, historically informed, often reaching out beyond the boundaries of philosophy; they are public intellectuals, taken seriously as contributors to debates outside the academy. Gary Gutting tells the story of the development of a distinctively French philosophy in the last four decades of the 20th century. His aim is to arrive at an account of what it was to 'do philosophy' (...) in France, what this sort of philosophizing was able to achieve, and how it differs from the analytic philosophy dominant in Anglophone countries. -/- His initial focus is on the three most important philosophers who came to prominence in the 1960s: Michel Foucault, Gilles Deleuze, and Jacques Derrida. He sets out the educational and cultural context of their work, as a basis for a detailed treatment of how they formulated and began to carry out their philosophical projects in the 1960s and 1970s. He gives a fresh assessment of their responses to the key influences of Hegel and Heidegger, and the fraught relationship of the new generation to their father-figure Sartre. He concludes that Foucault, Derrida, and Deleuze can all be seen as developing their fundamental philosophical stances out of distinctive readings of Nietzsche. The second part of the book considers topics and philosophers that became prominent in the 1980s and 1990s, such as the revival of ethics in Levinas, Derrida, and Foucault, the return to phenomenology and its use to revive religious experience as a philosophical topic, and Alain Badiou's new ontology of the event. Finally Gutting brings to the fore the meta-philosophical theme of the book, that French philosophy since the 1960s has been primarily concerned with thinking the impossible. (shrink)

This paper argues (a) that the concept of “potential being” is central to the theory and practice of contemporary cosmology and evolutionary science, and (b) that the reality of potential being points to the existence of an intelligent and purposive cause of the intelligible order among potential beings that existed from the first moments of the Big Bang. The paper introduces and explains the concept of “potential being” and then traces the existence of potential beings back to the beginnings of (...) the cosmos at the instant of the Big Bang. This primeval existence of potential beings is shown to possess a character and order that points to a cause external to that order. The paper concludes with a consideration of the features that must be possessed by that external cause in order to make sense of what we know. (shrink)

Davidson's paratactic account of indirect quotation preserves the apparent relational structure of indirect speech but without assuming, in the Fregean manner, that the thing said by a sayer is a proposition. I argue that this is a mistake. As has been recognised by some critics, Davidson's account suffers from analytical shortcomings which can be overcome by redeploying the paratactic strategy as a means of referring to propositions. I offer a quick and comprehensive survey of these difficulties and a concise propositional (...) solution. Further, I argue that Davidson's more general philosophical commitments provide no reason not to embrace the propositional strategy: despite appearances, to invoke propositions in the way suggested is consistent with Davidson's holism and consequent doctrine of semantic indeterminacy.

In Chapter 4 of [2] Grünbaum sets out to refute Einstein's philosophy of physical geometry. The latter's theory is seen as lying within the tradition of "anti-empiricist conventionalism" of Duhem and Quine as opposed to the "qualified empiricism" of Poincaré, Carnap and Reichenbach. Consequently Grünbaum sets the stage for his critique of Einstein by discussing certain of the views of these other thinkers. But in these preliminary discussions the various theses are confused and misrepresented in such a way as to (...) make it almost impossible to evaluate Grünbaum's final treatment of Einstein's thesis. For this reason I will deal only with those parts of this chapter in which the roots of Grünbaum's confusion are to be found. This will involve analyses of two theories which are not clearly distinguished by Grünbaum. The first is Duhem's denial of the "crucial experiment" in physics; the second is Quine's version of "pragmatism.". (shrink)

Vertes & Eastman argue against the popular idea that dreams promote memory consolidation and suggest instead that REM provides periodic endogenous stimulation during sleep. Although we suspect that much of the debate on the function of dreams reflects a too eager acceptance of the “adaptationist program,” we nonetheless support the position of the authors and propose a specific advantage of periodic REM activity.

Standard treatments of responsibility have been preoccupied with issues of blame and punishment, and concerns about free will. In contrast, Raz is concerned with problems about responsibility that arise from the “puzzle of moral luck,” puzzles that lead to misguided skepticism about negligence. We are responsible not only for conduct that is successfully guided by what we take to be our reasons for action, but also for misexercises of our rational capacities that escape our rational control. To deny this is (...) to lose sight of the ways “moral luck” is an inescapable feature of our agential engagement in the world. The present essay attempts to set out Raz’s argument as sympathetically as possible. Raz’s shift of focus is a powerful counter to current tendencies and points us in new and promising directions. Nonetheless, as it stands, it may just relocate skepticism about negligence to a different place. (shrink)

The current study analyzes trans-cultural universalities and specificities in the recognition of status roles, dominance perception and social evaluation based on nonverbal cues. Using a novel methodology, which allowed to mask clues to ethnicity and cultural background of the agents, we compared impression of Germans, Americans and Arabs observing computer-animated interactions from the three countries. Only in the German stimulus sample the status roles could be recognized above chance level. However we found significant correlations in dominance perception across all countries. (...) Significant correlations were only found for evaluation between German observers and observers from the other two countries. Perceived dominance uniformly predicted the assignment of status-roles in all cultures. Microanalysis of movement behavior further revealed predictive value of specific nonverbal cues for dominance ratings. Results support the hypothesis of universalities in the processing of dominance cues and point to cultural specificities in evaluative responses to nonverbal behavior. (shrink)

According to the naive theory of belief reports, our intuition that “Lois believes that Kent flies” is false results from our mistakenly identifying what this sentence implicates, which is false, with what it says, which is true. Whatever the merits of this proposal, it is here argued that the naive theory’s analysis of negative belief reports—sentences such as “Lois doesn't believe that Kent flies”—gives rise to equally problematic clashes with intuition, but that in this case no “pragmatic” explanation is available. (...) In particular, it is argued that there are situations at which, although “Lois believes that Superman flies” and “Lois doesn't believe that Kent flies” appear consistent, a speaker must contradict himself when he utters both. It is also argued that the hidden-indexical theory of belief reports—which otherwise respects our ordinary intuitions regarding belief reports—similarly fails to explain this intuition. (shrink)

The temporally immediate transcendence of space through the use of the telephone creates a bi-localized space of interaction. Unique structures of spatial experience are constituted through the intending of spatial sectors in telephonic conversation. In the first section of this paper, six eidetic variations are presented that establish the various ways in which environmental sectors are intended through the intersubjective space of the telephonic medium. The telos of these descriptions is to characterize changes in social praxis that have been made (...) available with the inclusion in the life-world of the telephone as a typical tool. In the second section, a constitutive analysis is undertaken in order to investigate how empty intentions are brought to fulfillment in the telephonic conversational thematizations of environmental sectors. Telephone space involves a modified we-relationship through which meaning-intentions are intersubjectively synthesized, yet from bi-local environmental standpoints. The intersubjective achievements concerning projects grounded within the immediacy of telephonic transcendence create a unique structure of meaning-fulfillment. (shrink)

Quantum mechanics - central not only to physics, but also to chemistry, materials science, and other fields - is notoriously abstract and difficult. Essential Quantum Mechanics is a uniquely concise and explanatory book that fills the gap between introductory and advanced courses, between popularizations and technical treatises.By focusing on the fundamental structure, concepts, and methods of quantum mechanics, this introductory yet sophisticated work emphasizes both physical and mathematical understanding. A modern perspective is adopted throughout - the goal, in part, being (...) to gain entry into the world of 'real' quantum mechanics, as used by practicing scientists.With over 60 original problems, Essential Quantum Mechanics is suitable as either a text or a reference. It will be invaluable to physics students as well as chemists, electrical engineers, philosophers, and others whose work is impacted by quantum mechanics, or who simply wish to better understand this fascinating subject.
