The book_ Fate, Time, and Language: An Essay on Free Will_, published in 2010 by Columbia University Press, presented David Foster Wallace's challenge to Richard Taylor's argument for fatalism. In this anthology, notable philosophers engage directly with that work and assess Wallace's reply to Taylor as well as other aspects of Wallace's thought. With an introduction by Steven M. Cahn and Maureen Eckert, this collection includes essays by William Hasker, Gila Sher, Marcello Oreste Fiocco, Daniel R. Kelly, Nathan Ballantyne, (...) Justin Tosi, and Maureen Eckert. These thinkers explore Wallace's philosophical and literary work, illustrating remarkable ways in which his philosophical views influenced and were influenced by themes developed in his other writings, both fictional and nonfictional. Together with _Fate, Time, and Language_, this critical set unlocks key components of Wallace's work and its traces in modern literature and thought. (shrink)
Twenty-nine philosophers from Plato to William Luijpen are represented by selections varying from three to twenty-two pages in length. The selections and their proportions are simply too idiosyncratic. Why should Stephen Strasser get twenty-two pages while Plato, Aquinas, Descartes, and Hume manage only twenty-nine total pages among the four of them? Most of the classical philosophers are represented by mere snippets; Kant is high man with fifteen pages of text—and even these are broken up into seven sections. The issue (...) is not simply number of pages: after all, Leibniz' Monadology would have fit in less space than that accorded to John Peters. This is not to denigrate Peters, who was an exceptionally good philosopher; but the beginning student should be exposed to Leibniz, Hegel, and Marx before he is exposed to Peters. Or he should at least be exposed to Smart, Feigl, or some other contemporary naturalistic viewpoint along with Peters, Teilhard de Chardin, and Merleau-Ponty. How, for example, can one begin to appreciate the task Merleau-Ponty has set for himself in philosophical psychology unless one has become familiar with the behavioristic and reductionistic positions Merleau-Ponty is defining himself over and against? The bibliographies in the first part of the book are inadequate.—E. A. R. (shrink)
This book of readings would make a superb ancillary text for an advanced or even graduate course in "existential phenomenology." Twelve of the twenty-two selections have been translated for the first time into English. This includes Sartre's defense of the major theses of Being and Nothingness before the Société française de philosophie and Ric£ur's similar defense of La Philosophie de la Volonté, I before the same body. As with Merleau-Ponty's similar defense, "The Primacy of Perception," also included in this volume, (...) the discussion which followed these defenses is presented. Integral texts in the form of articles rather than extracts from books are presented in most cases, including the first appearance of an essay by Marcel entitled "Desire and Hope." Where this is not done, as is partly the case for Strasser and wholly the case for Scheler, Dufrenne, Wild, and Ingarden, lengthy and context-faithful excerpts are given. There are four sections in the book: I. Existence in the Modalities of Consciousness, II. Existence as Embodied, III. Existence and Value, and IV. Existence and the Human Sciences. Each of these sections is skillfully laid out and effectively introduced. In addition to the philosophers mentioned, work by Buytendijk, May, Schutz, Van Kaam, Berger, Bollnow, Minkowski, Straus, and de Waelhens is included. Husserl is missing, as is Heidegger, but these gaps can be supplemented easily enough.—E. A. R. (shrink)
This book is a splendid piece of editing. Its format is tripartite: a consideration of specifically Husserlian themes, such as intersubjectivity, reduction, the life-world, intentionality, and constitution by distinguished Husserlian scholars and, in two instances, Husserl himself; the translation and adaptation of phenomenology into existential phenomenology, the illustration of which is centered around selections from Heidegger, Sartre, and Merleau-Ponty with commentary support from Kockelmans, Schrag, Edie, Kwant, Natanson, and Spiegelberg; the exemplary deployment of phenomenology into the area of the human (...) sciences, particularly psychology. In this last part the uniformly solid though sometimes non-harmonious interpretations of the relation between phenomenology and psychology are proffered by Merleau-Ponty, Sartre, Kockelmans, Strasser, and Schuetz. This book would provide excellent supplementary reading for any course in phenomenology or existential phenomenology, and, in addition, for any course in the philosophy of the social sciences.—E. A.

Abstract The present field experiment was designed to explore the effectiveness of social learning and structural developmental prescriptions for moral pedagogy in a summer sports camp. Eighty?four children, aged five to seven years, were matched on relevant variables and randomly assigned to one of three classes: (a) social learning, (b) structural developmental, or (c) control. Each of the classes shared similar curricula and was taught by two trained instructors for a six?week period. Educators is the experimental conditions implemented theoretically grounded (...) instructional strategies in their weekly emphasis on specific moral themes. Analyses indicated significant pre?to?post gains on a Piagetian intentionality task and a measure of distributive justice within both experimental groups, but MANCOVA results indicated differences between the experimental and control conditions only approached significance.

What allows MNCs to maintain their sustainability practices over the long-term? This is an important but under-examined question. To address this question, we investigate both the development and sustenance of sustainability practices. We use the dynamic capabilities perspective, rooted in resource-based view literature, as the theoretical basis. We argue that MNCs that simultaneously pursue both higher R&D intensity and higher internationalization are more capable of developing and maintaining sustainability practices. We test our hypotheses using longitudinal panel data from 1989 to (...) 2009. Results suggest that MNCs that have a combination of both high R&D intensity and high internationalization are (i) likely to develop more sustainability practices and (ii) are likely to maintain more of those practices over a long-term. As a corollary, MNCs that have a combination of both low R&D and low internationalization usually (i) end up developing little or no sustainability practices and (ii) find it difficult to sustain whatever little sustainability practices they might have developed.

This essay examines the origin of genotype-environment interaction, or G×E. "Origin" and not "the origin" because the thesis is that there were actually two distinct concepts of G×E at this beginning: a biometric concept, or \[G \times E_B\], and a developmental concept, or \[G \times E_D \]. R. A. Fisher, one of the founders of population genetics and the creator of the statistical analysis of variance, introduced the biometric concept as he attempted to resolve one of the main problems in (...) the biometric tradition of biology - partitioning the relative contributions of nature and nurture responsible for variation in a population. Lancelot Hogben, an experimental embryologist and also a statistician, introduced the developmental concept as he attempted to resolve one of the main problems in the developmental tradition of biology - determining the role that developmental relationships between genotype and environment played in the generation of variation. To argue for this thesis, I outline Fisher and Hogben's separate routes to their respective concepts of G × E; then these separate interpretations of G × E are drawn on to explicate a debate between Fisher and Hogben over the importance of G × E, the first installment of a persistent controversy. Finally, Fisher's \[G \times E_B\] and Hogben's \[G \times E_D \] are traced beyond their own work into mid-2Oth century population and developmental genetics, and then into the infamous IQ Controversy of the 1970s.

l. There is an antinomy in Hare's thought between Ought-Implies-Can and No-Indicatives-from-Imperatives. It cannot be resolved by drawing a distinction between implication and entailment. 2. Luther resolved this antinomy in the l6th century, but to understand his solution, we need to understand his problem. He thought the necessity of Divine foreknowledge removed contingency from human acts, thus making it impossible for sinners to do otherwise than sin. 3. Erasmus objected (on behalf of Free Will) that this violates Ought-Implies-Can which he (...) supported with Hare-style ordinary language arguments. 4. Luther a) pointed out the antinomy and b) resolved it by undermining the prescriptivist arguments for Ought-Implies-Can. 5. We can reinforce Luther's argument with an example due to David Lewis. 6. Whatever its merits as a moral principle, Ought-Implies-Can is not a logical truth and should not be included in deontic logics. Most deontic logics, and maybe the discipline itself, should therefore be abandoned. 7. Could it be that Ought-Conversationally-Implies-Can? Yes - in some contexts. But a) even if these contexts are central to the evolution of Ought, the implication is not built into the semantics of the word; b) nor is the parallel implication built into the semantics of orders; and c) in some cases Ought conversationally implies Can, only because Ought-Implies-Can is a background moral belief. d) Points a) and b) suggest a criticism of prescriptivism - that Oughts do not entail imperatives but that the relation is one of conversational implicature. 8. If Ought-Implies-Can is treated as a moral principle, Erasmus' argument for Free Will can be revived (given his Christian assumptions). But it does not 'prove' Pelagianism as Luther supposed. A semi-Pelagian alternative is available. (shrink)
Where Deleuze and Guattari introduce us to “lines of flight,” they transcode the mechanics of “flight” through “capture,” fomenting what is understood by many as Deleuze’s philosophical thesis: forging an analog relationship between univocity and difference via multiplicitious immanence. This is, of course, posed against Freud’s molar unities in their second chapter “One or Several Wolves.” Thus, if Heidegger is the philosopher par excellance of queries between hermeneutics and immanence (the philosopher of anti-immanence), it is Deleuze who asks “what is (...) the relationship between immanence and multiplicity?” While, for radical immanence qua Laruelle and post-Laruelleans, Deleuze is confounded with multiplicity (caught in an eternal Prometheun ἰσονομία (isonomia) where there is no victor), for Deleuze multiplicity and difference are two components that can fit together adeptly. Guided by the principle of univocity, Deleuze describes a world of pure multiplicity—all multiplicities are equally immanent within nature. As Whitehead spoke of “occasions,” Deleuze speaks of specific gatherings (of heterogeneous multiplicities), dubbed “assemblages,” that occasion themselves as blips – blips of singularity on an otherwise smooth plane. Following philosopher Levi R. Bryant's account of "dim media," I situate political lines of flight qua psychogeographies vis-a-vis urban topology. (shrink)
Cognitive architectures have often been applied to data from individual experiments. In this paper, I develop an ACT-R reader that can model a much larger set of data, eye-tracking corpus data. It is shown that the resulting model has a good fit to the data for the considered low-level processes. Unlike previous related works, the model achieves the fit by estimating free parameters of ACT-R using Bayesian estimation and Markov-Chain Monte Carlo techniques, rather than by relying on the mix of (...) manual selection + default values. The method used in the paper is generalizable beyond this particular model and data set and could be used on other ACT-R models. (shrink)
A restriction of R-Mingle with the variable-sharing property and the Ackermann properties is defined. From an intuitive semantical point of view, this restriction is an alternative to Anderson and Belnap’s logic of entailment E.
There are two motivations commonly ascribed to historical actors for taking up statistics: to reduce complicated data to a mean value (e.g., Quetelet), and to take account of diversity (e.g., Galton). Different motivations will, it is assumed, lead to different methodological decisions in the practice of the statistical sciences. Karl Pearson and W. F. R. Weldon are generally seen as following directly in Galton’s footsteps. I argue for two related theses in light of this standard interpretation, based on a reading (...) of several sources in which Weldon, independently of Pearson, reflects on his own motivations. First, while Pearson does approach statistics from this "Galtonian" perspective, he is, consistent with his positivist philosophy of science, utilizing statistics to simplify the highly variable data of biology. Weldon, on the other hand, is brought to statistics by a rich empiricism and a desire to preserve the diversity of biological data. Secondly, we have here a counterexample to the claim that divergence in motivation will lead to a corresponding separation in methodology. Pearson and Weldon, despite embracing biometry for different reasons, settled on precisely the same set of statistical tools for the investigation of evolution. (shrink)
Dr. B.R. Ambedkar is one of the names who advocated to change social order of the age-old tradition of suppression and humiliation. He was an intellectual, scholar, statesman and contributed greatly in the nation building. He led a number of movements to emancipate the downtrodden masses and to secure human rights to millions of depressed classes. He has left an indelible imprint through his immense contribution in framing the modern Constitution of free India. He stands as a symbol of struggle (...) for achieving the Social Justice. We can assign several roles to this great personality due to his life full dedication towards his mission of eradicating evils from Indian society. The social evils of Indian society, also neglected this great personality even in intellectual sphere too. The so-called intellectuals of India not honestly discussed his contribution to Indian intellectual heritage, rather what they discussed, also smells their biases towards a Dalit literate and underestimated his great personality. This paper will attempt to discuss important facts about life and a short description of the literature written by Dr. B.R. Ambedkar. This is followed by discussion his philosophy in the five major sections i.e. Feminism and women empowerment, philosophy of education, ideas on social justice and equality, philosophy of politics and economics and philosophy of religion.

This paper first shows that some versions of the logic R of Relevance do not satisfy the relevance principle introduced by Anderson and Belnap, the principle of which is generally accepted as the principle for relevance. After considering several possible (but defective) improvements of the relevance principle, this paper presents a new relevance principle for (three versions of) R, and explains why this principle is better than the original and others.
We study the filter ℒ*(A) of computably enumerable supersets (modulo finite sets) of an r-maximal set A and show that, for some such set A, the property of being cofinite in ℒ*(A) is still Σ0 3-complete. This implies that for this A, there is no uniformly computably enumerable “tower” of sets exhausting exactly the coinfinite sets in ℒ*(A).
In this chapter we argue that Robert Hare's psychopathy checklist revised (PCL-R) offers a construct of psychopathy that is valid enough for philosophical investigations of the moral and legal responsibility of psychopathic offenders.
Values are an important part of human existence, his society and human relations. All social, economic, political, and religious problems are in one sense is reflection of this special abstraction of human knowledge. We are living in a globalized village and thinking much about values rather than practice of it. If we define religion and spirituality we can say that religion is a set of beliefs and rituals that claim to get a person in a right relationship with God, and (...) spirituality is a focus on spiritual things and the spiritual world instead of physical/earthly things. If we think rationally we can find the major evils related to religion exiting in present society are due to lack of proper understanding of religion and spirituality. If we really know our own religions and values associated with it, we can create a beautiful world, full or love and respect for each and every human being. The proper knowledge and practice of any religion’s values can make an integrated man. In the book, The Buddha and His Dhamma, Dr. Ambedkar elucidated the significance and importance of Dhamma in human life. The Dhamma maintained purity of life, which meant abstains from lustful, evil practices. The Dhamma is a perfection of life and giving up craving. Dhamma’s righteousness means right relation of man to man in all sphere of life. The basic idea underlying religion is to create an atmosphere for the spiritual development of the individual. He said that Knowing the proper ways and means is more important than knowing the ideal. The major objective of this paper is to the study the religious philosophy of Dr. B.R. Ambedkar and to study how he established that religious and spiritual values enables religious people in particular and humanity at large to solve contemporary problems. (shrink)
In his work on personal identity, Derek Parfit makes two revolutionary claims: firstly, that personal identity is not what matters in survival; and secondly, that what does matter is relation R. In this article I demonstrate his position here to be inconsistent, with the former claim being defensible only in case the latter is false. Parfit intends his famous fission argument to establish the unimportance of identity – a conclusion disputed by, among others, Mark Johnston. My approach is to critically (...) assess their debate, focusing on Johnston's reductio of Parfit's position. I contend that although Parfit's own response fails, there are other ways to save the fission argument. The unimportance of identity then comes at a cost, however, because the reductio can only be avoided by accepting either that nothing matters in survival, or else that facts about particles and forces do. Either way, relation R cannot be what matters. (shrink)
A recent article by Vihalemm (Foundations of Chemistry, 2003) is critical of an earlier essay. We find that there is some justification for his criticism of vagueness in defining terms. Nevertheless the main conclusions of the earlier work, when carefully restated to deflect Vihalemm’s criticisms, are unaffected by his arguments. The various dicta that are used as the bases of chemical explanations are different in character, and are used in a different way from the laws and theories in classical physics.
The game theoretical approach to R&D cooperation does not investigate the role of trust in the initiation and success of R&D cooperation: it either assumes that firms are non-opportunists or that the R&D cooperation is supported by an incentive mechanism that eliminates opportunism. In contrast, the present paper focuses on these issues by introducing incomplete information and two types of firms: opportunist and non-opportunist. Defining trust as the belief of each firm that its potential collaborator will respect the contract, it (...) identifies the trust conditions under which firms initiate R&D alliances and contribute to their success. The higher the spillovers, the higher the level of trust required to initiate R&D cooperation for non-opportunists, while the inverse holds for opportunists. (shrink)
Husserl on the Ego and its Eidos (Cartesian Meditations, IV) ALFREDO FERRARIN THE THEORY OF the intentionality of consciousness is essential for Husserl's philosophy, and in particular for his mature theory of the ego. But it runs into serious difficulties when it has to account for consciousness's transcendental constitution of its own reflective experience and its relation to immanent time. This intricate knot, the inseparability of time and constitution, is most visibly displayed in Husserl's writings from the 192os up to (...) the notion of the eidos ego in the fourth Cartesian Meditation. In this paper I want to dwell on the most problematic aspects of this theory. After a few preliminary remarks about the intentionality of consciousness (sec- tion 1), I try to place the theory of the substrate of habitualities in the context of Husserl's evolution on the issue of the reflection of the ego on itself (section ~). I briefly follow the threads of Husserl's shifting position from the Logical Investi- gat/ons and Ideas I to Ideas II, the Cartesian Meditations and the Cr/s/s.

Husserl's Entwicklungsgeschichte on the topic of the pure ego has already been the object of important scholarly works, of which Kern's 1964 Husserl und Kant seems to me the best example. But what the secondary literature does not do is develop thematically the ambiguities of Husserl's definitions of consciousness and temporality in a unitary and comprehensive way. While I follow the lead of Berger, Broekman, Kern, Marbach,' and others, I find that their work does not sufficiently stress the difficulties at the core ofintentionality and reflective time- consciousness. Therefore, although section 2 is a necessary presupposition for drawing some critical conclusions in the final two sections, it does not exhaust my theme. After clarifying the peculiarity of the notions of essence, intuition, tran- scendental and apriori, as well as their irl:educibility to a Kantian meaning, I turn to the "de facto transcendental ego" resulting from eidetic variation (section 3) in order to introduce an examination of temporality. The difficul- ties in the twofold requirement, namely, that consciousness be the identical subject of its Erlebnisse and be synthetically unified in time, concern the unity, primacy, and mutual relation of time and consciousness in the constitution of our experience. They have been heady pointed out by Ricoeur in his commen- tary on the Cartesian Meditations. But what I want to argue in section 4, going beyond Ricoeur's text, is that the tension between temporally constituted and constitutive consciousness in the ego's reflection on its own retentions and protensions does not simply make the question of time ambiguous, but has crucial and problematic bearings on the very definition of consciousness as intentionality. In this respect... -/- . (shrink)
Group selection is increasingly being viewed as an important force in human evolution. This paper examines the views of R.D. Alexander, one of the most influential thinkers about human behavior from an evolutionary perspective, on the subject of group selection. Alexander's general conception of evolution is based on the gene-centered approach of G.C. Williams, but he has also emphasized a potential role for group selection in the evolution of individual genomes and in human evolution. Alexander's views are internally inconsistent and (...) underestimate the importance of group selection. Specific themes that Alexander has developed in his account of human evolution are important but are best understood within the framework of multilevel selection theory. From this perspective, Alexander's views on moral systems are not the radical departure from conventional views that he claims, but remain radical in another way more compatible with conventional views.

Both in An Autobiography and in An Essay on Metaphysics R.G. Collingwood defines the study of metaphysics as primarily at any time an attempt to discover the absolute presuppositions of thinking and secondarily as an attempt to discover the corresponding absolute presuppositions of other peoples and other times, and to follow the historical process by which one set of presuppositions has turned into another. In addition, he states that the distinction between what is true and what is false does not (...) apply to them. The objection often raised against this definition is that it has nothing to do with metaphysics in the traditional sense and that it only refers to a history of ideas. In this article I try to show the link between Collingwood's apparently idiosyncratic definition of metaphysics and the traditional one. I, therefore, have to sketch the background against which Collingwood's concept of metaphysics and the peculiar terminology he makes use of must be interpreted. This reconstruction of the original background is necessary in order to make clear what Collingwood means by his project of a „reformed metaphysics" as a historical inquiry into the absolute presuppositions of human thinking about reality.

Until recently, sex determination in mammals has often been described as a male determination process, with male differentiation being the active and dominant pathway, and only in its absence is the passive female pathway followed. This picture has been challenged recently with the discovery that the gene encoding R-spondin1 is mutated in human patients with female-to-male sex reversal.((1)) These findings might place R-spondin1 in the exceptional position of being the female-determining gene in mammals. In this review, possible roles of R-spondin1 (...) during sex determination as well as questions arising from this study will be discussed. (shrink)
Legal translation has become a principal means to unfold Chinese laws to the world in the global era and the study of it has proved to be of practical significance. Since the proper theory guidance is the key to the quality of LT translation, this paper focuses on the Skopos theory and the strategies applied in the practice of LT. A case study of LT examples from the Criminal Law of the P.R.C. has been made while briefly reviewing the Skopos (...) theory and its principles. Started with short discussion of LT, this paper probes into the applicability of the three principles of Skopos theory, including the Skopos rule, the coherence rule and the fidelity rule, into the legal texts, especially into the translation of the Criminal Law of the P.R.C. and based on the study, the strategies for LT are proposed, with the hope that it can be useful for reference in other legal texts.

Starting from the premise that firms are distinct in terms of their capacity to create innovations, this article explores the rationale for R&D cooperation and the choice between alliances that involve information sharing, cost sharing or both. Defining innovative capability as the probability of creating an innovation, it examines firm strategy in a duopoly market, where firms have to decide whether or not to cooperate to acquire a fixed cost R&D infrastructure that would endow each firm with a firm-specific innovative (...) capability. Furthermore, since emerging industries are often characterized by high technological uncertainty and diverse firm focus that makes the exploitation of spillovers difficult, this article focuses on a zero spillover context. It demonstrates that asymmetry has an impact on alliance choice and social welfare, as a function of ex-post market competition and fixed costs of R&D. With significant asymmetry no alliance may be formed, while with similar firms the cost sharing alliance is dominant. Finally, it ascertains the settings under which the equilibrium outcome is distinct from that maximizing social welfare, thereby highlighting some conditions under which public investment in a technology park can be justified.

Kinetic models using enzyme kinetics are developed for the three ways that Louie proved that Rosen’s minimal (M-R)-System can be closed to efficient cause; i.e., how the “replication” component can itself be entailed from within the system. The kinetic models are developed using the techniques of network thermodynamics. As a demonstration, each model is simulated using a SPICE circuit simulator using arbitrarily chosen rate constants. The models are built from SPICE sub-circuits representing the key terms in the chemical rate equations. (...) The models include the addition of an ad hoc semi-permeable membrane so the system can achieve steady state fluxes and also to illustrate the need for all the efficient cause agents to be continually replaced. Comments are made about exactly what is being simulated. (shrink)

A well-known theorem by Martin asserts that the degrees of maximal sets are precisely the high recursively enumerable degrees, and the same is true with ‘maximal’ replaced by ‘dense simple’, ‘r-maximal’, ‘strongly hypersimple’ or ‘finitely strongly hypersimple’. Many other constructions can also be carried out in any given high r. e. degree, for instance r-maximal or hyperhypersimple sets without maximal supersets . In this paper questions of this type are considered systematically. Ultimately it is shown that every conjunction of simplicity- (...) and non-extensibility properties can be accomplished, unless it is ruled out by well-known, elementary results. Moreover, each construction can be carried out in any given high r. e. degree, as might be expected. For instance, every high r. e. degree contains a dense simple, strongly hypersimple set A which is contained neither in a hyperhypersimple nor in an r-maximal set. The paper also contains some auxiliary results, for instance: every r. e. set B can be transformed into an r. e. set A such that A has no dense simple superset, the transformation preserves simplicity- or non-extensibility properties as far as this is consistent with , and A [TRIPLE BOND]TB if B is high, and A ≥TB otherwise. Several proofs involve refinements of known constructions; relationships to earlier results are discussed in detail. (shrink)
