A driving force behind much of the literature on the non-identity problem is the widely shared intuition that actions or policies that change who comes into existence don't, as a result, lose their morally problematic features. We hypothesize that this intuition isn’t entirely shared by the general public, which might have widespread implications concerning how to best motivate public support for large-scale, identity-affecting policies like those involved in climate change mitigation. To test our hypothesis, we ran a behavioural economic experiment, (...) a version of the well-known dictator game, designed to mimic the public's morally loaded behaviour in identity-affecting choice problems. As predicted, we found that the public does seem to behave more selfishly when making identity-affecting choices. We further hypothesised that one possible mechanism involved in this change is the notion of harm that plays a role in the public’s normatively loaded decision making. So, during our study, we also solicited subjects’ attitudes about harm, in particular about whether the “dictators” had done harm through their choices. The data suggest that substantial portions of the population each employ distinct notions of harm in their normative thinking, which raises some puzzling features about the public’s normative thinking that call out for further empirical examination.

Collaboration is increasingly popular across academia. Collaborative work raises certain ethical questions, however. How will the fruits of collaboration be divided? How will the work for the collaborative project be split? In this paper, we consider the following question in particular. Are there ways in which these divisions systematically disadvantage certain groups? -/- We use evolutionary game theoretic models to address this question. First, we discuss results from O'Connor and Bruner (unpublished). In this paper, we show that underrepresented groups (...) in academia can be disadvantaged in such situations by dint of their small numbers. Second, we present novel results exploring how the hierarchical structure of academia can lead to bargaining disadvantage. We investigate models where one actor has a higher baseline of academic success, less to lose if collaboration goes south, or greater rewards for non-collaborative work. We show that in these situations, the less powerful partner is disadvantaged in bargaining over collaboration. (shrink)

In this paper we use an experimental approach to investigate how linguistic conventions can emerge in a society without explicit agreement. As a starting point we consider the signaling game introduced by Lewis. We find that in experimental settings, small groups can quickly develop conventions of signal meaning in these games. We also investigate versions of the game where the theoretical literature indicates that meaning will be less likely to arise—when there are more than two states for actors to transfer (...) meaning about and when some states are more likely than others. In these cases, we find that actors are less likely to arrive at strategies where signals have clear conventional meaning. We conclude with a proposal for extending the use of the methodology of experimental economics in experimental philosophy. (shrink)

D. Justin Coates argues that, in ‘Freedom and Resentment’, P. F. Strawson develops a modest transcendental argument for the legitimacy of our moral responsibility practices. I disagree with Coates’ claim that Strawson’s argument provides a justification, in Wittgenstein’s and/or Strawson’s sense of that term, of our responsibility practices. I argue that my interpretation of Strawson solves some difficulties with Coates’ argument, while retaining its advantages.

Abstract: This paper restates the thesis of 'The Requirements of Justice and Liberal Socialism" where it was argued that liberal socialism best meets Rawlsian requirements of justice. The recent responses to this paper by Jan Narveson, Jeppe von Platz, and Alan Thomas merit examination and comment. This paper shows that if Rawlsian justice is to be met, then non-personal property must be subject to public control. If just outcomes merit the public control of non-personal property and this control is not (...) utilized, then justice has been subordinated to the objectively less important institution of private property.

Students often invoke quantum mechanics in class or papers to make philosophical points. This tendency has been encouraged by pop culture influences like the film What the Bleep do We Know? There is little merit to most of these putative implications. However, it is difficult for philosophy teachers unfamiliar with quantum mechanics to handle these supposed implications in a clear and careful way. This paper is a philosophy of science version of MythBusters. We offer a brief primer on the nature (...) of quantum mechanics, enumerate nine of the most common implications associated with quantum mechanics, and finally clarify each implication with the facts. Our goal is to explain what quantum mechanics doesn’t show. (shrink)

This is a transcript of a conversation between P F Strawson and Gareth Evans in 1973, filmed for The Open University. Under the title 'Truth', Strawson and Evans discuss the question as to whether the distinction between genuinely fact-stating uses of language and other uses can be grounded on a theory of truth, especially a 'thin' notion of truth in the tradition of F P Ramsey.

DOI: 10.1080/00031305.2018.1564697 When the editors of Basic and Applied Social Psychology effectively banned the use of null hypothesis significance testing (NHST) from articles published in their journal, it set off a fire-storm of discussions both supporting the decision and defending the utility of NHST in scientific research. At the heart of NHST is the p-value which is the probability of obtaining an effect equal to or more extreme than the one observed in the sample data, given the null hypothesis and (...) other model assumptions. Although this is conceptually different from the probability of the null hypothesis being true, given the sample, p-values nonetheless can provide evidential information, toward making an inference about a parameter. Applying a 10,000-case simulation described in this article, the authors found that p-values’ inferential signals to either reject or not reject a null hypothesis about the mean (α = 0.05) were consistent for almost 70% of the cases with the parameter’s true location for the sampled-from population. Success increases if a hybrid decision criterion, minimum effect size plus p-value (MESP), is used. Here, rejecting the null also requires the difference of the observed statistic from the exact null to be meaningfully large or practically significant, in the researcher’s judgment and experience. The simulation compares performances of several methods: from p-value and/or effect size-based, to confidence-interval based, under various conditions of true location of the mean, test power, and comparative sizes of the meaningful distance and population variability. For any inference procedure that outputs a binary indicator, like flagging whether a p-value is significant, the output of one single experiment is not sufficient evidence for a definitive conclusion. Yet, if a tool like MESP generates a relatively reliable signal and is used knowledgeably as part of a research process, it can provide useful information. (shrink)

This article provides an overview of P.T. Raju’s Neo-Vedantic philosophy of I-am and a relationalist assessment of it.

This paper is a detailed examination of some parts of J. P. Moreland's book on "the argument from consciousness". (There is a companion article that discusses the parts of the book not taken up in this critical notice.).

Huey P. Newton, founder of the Black Panther Party, is perhaps one of the most interesting and intriguing American intellectuals from the last half of the 20th century. Newton’s genius rested in his ability to amalgamate and synthesize others’ thinking, and then reinterpreting and making it relevant to the situation that existed in the United States in his time, particularly for African-Americans in the densely populated urban centers in the North and West. Newton saw himself continuing the Marxist-Leninist tradition and (...) one of the most important aspects of his thought was his reinterpretation of Marxist class structure. This paper presents Newton’s position that it is the urban poor—who Newton identifies with the lumpenproletariat—that act as the revolutionary class that will bring about a change in the socio-economic order. To that end, there is first a discussion of Newton’s view of the lumpenproletariat and how it differs from the traditional Marxist understanding. Then there is an explanation of the role of the vanguard and its relationship to the lumpenproletariat. The paper concludes with a comparison of Frantz Fanon’s and Newton’s understanding of the lumpenproletariat, and responds to the “problem of lumpenization” in the Black Panther Party. (shrink)

This article is a discussion of the political thought of Huey P. Newton, and by extension, the theory and practice of the Black Panther Party. More specifically, this article will explore a tension that exists between Newton's theory of Intercommunalism and the Black Panther Party Platform. To that end, there is, first, a discussion of the ideological development of the Black Panther Party, which culminated in Newton's theory of Intercommunalism. Second, there is a presentation of what will be broadly construed (...) as the Party Platform, which articulates the basic principles and practices of the Black Panther Party. Finally, there is a discussion of several ways in which there seems to be a conflict between Newton's ideology and his political practice. While some are only apparent contradictions, there does remain a deep conflict between the dialectical basis of Intercommunalism and the foundational basis of the Party Platform. (shrink)

In the face of continuing assumptions by many scientists and journal editors that p-values provide a gold standard for inference, counter warnings are published periodically. But the core problem is not with p-values, per se. A finding that “p-value is less than α” could merely signal that a critical value has been exceeded. The question is why, when estimating a parameter, we provide a range (a confidence interval), but when testing a hypothesis about a parameter (e.g. µ = x) we (...) proceed as if “=” entails exact equality of the parameter with x. That standard is hard to meet, and is not a standard expected for power calculations, where we are satisfied to reject a null hypothesis H0 if the result is merely “detectably” different from (exact) H0. This paper explores, with resampling (simulation) methods, the impacts on p-values, and alternatives, if the null hypothesis is defined as a thick or thin range of values. It also examines, empirically, the extent to which the p-value may or may not be a good predictor of the probability that H0 is true, given the distribution of the data. (shrink)

Rawls’s consideration not to include the choice of economic systems as part of a theory of justice is inconsistent with his comments on redistribution and the political effects of economic inequality. When Rawls’s discussion of economic systems and his discussion of economic inequalities is examined, it is apparent that the selection of economic systems is a pertinent topic for a theory of justice. The propensity for the primary social good of self-respect to be satisfied can be affected by the selection (...) of economic systems. Rawls has incorrectly determined the selection of economic systems to be unimportant if different economic systems can be more advantageous to the satisfaction of self-respect than others. When socialism and Rawls’s version of regulated capitalism are compared, socialism is a maximin solution, and accordingly will be selected by people within the original position under the veil of ignorance.

Hun Chung’s recent article “Rawls’s Self-Defeat: A Formal Analysis” argues that the selection of results equivalent to justice as fairness can be derived by utilitarianism. Chung argues that these results can be achieved through the use of Rawls’s constructed utility function from his work Justice as Fairness. Although Chung’s article is finely argued and presented in great detail, this paper will show that Chung made three mistakes in the fundamentals of his argument. First, Chung mistakes Rawls’s constructed utility function as (...) actually utilitarian. Second, Chung confuses the motivations and the assumptions of those held by agents in the original position and those held by utilitarian agents. Last, Chung’s previous mistakes result in the incorrect conclusion that an equal distribution of resources will be selected by representative agents instead of the unequal distribution prescribed by the difference principle.

G.A. Cohen attempts to provide a case for socialism that takes into consideration the reasons why socialism is desirable and some of the problems for its feasibility. He finds that the kind of community sentiment that socialism requires is possible, but the devices of social organization that can facilitate the growth of socialist sentiment along with the effective transmission of information are not currently known. In short, Cohen thinks social scientists and philosophers need to find out how to harness the (...) information transmission capacity of market exchange without the motivational encouragement of rapacious self-interest that market exchange fosters. This paper argues that Cohen’s appraisal of the ineffectiveness of informational transmission in socialist planned economies in incorrect. A democratically planned socialist economy can serve as the basis for the fostering of the socialist community sentiment that Cohen advocates along with the required transmission of economic information.

This paper will examine the three distributive problems of inequality, social scarcity, and environmental decay. All three of these problems are the result of economic growth that is not properly structured by institutions. It will be argued that each one of these distributive problems exacerbates the other two. Any solution to one of these problems must address the other two as well. This paper will show that these three distributive problems can be minimized through a combination of tax measures, institutional (...) changes, public employment creation, public service provision, and the nationalization of certain industries.

G.A. Cohen’s critique of the Rawlsian difference principle points out an inconsistency in its presentation. The initial equality decided by the participants in the original position under the veil of ignorance is not preserved by the inequality sanctioned by the difference principle. Cohen shows how the breakdown of the initial equality of the original position prevents the desired results of the Rawlsian system from being realized. Cohen argues that an egalitarian ethos is required within a society for equality preserving economic (...) distributions and Pareto superior outcomes to occur. Nonetheless, Cohen’s analysis of Rawls misses the ultimate cause of inequality, which is the dynamics of capital accumulation. An egalitarian ethos is only possible if there is a socialist mode of production to facilitate its development. Additionally, Cohen’s critique of Rawlsian constructivism through an argument for intuitionism does not address the natural-material existence of human beings. This existence must be considered for any advantageous social formation. (shrink)

Review of Craig And Mroeland: *Naturalism: A Critical Analysis*.

Even as dismissive of pursuing Comparative Philosophy for achieving East-West synthesis in philosophy, the author maintains the need for “open philosophizing.” “Open philosophizing” is one characterized by dialogical openness to culturally diverse philosophical traditions and thought-patterns.

While I was working about some basic physical phenomena, I discovered some geometric relations that also interest mathematics. In this work, I applied the rules I have been proven to P=NP? problem over impossibility of perpendicularity in the universe. It also brings out extremely interesting results out like imaginary numbers which are known as real numbers currently. Also it seems that Euclidean Geometry is impossible. The actual geometry is Riemann Geometry and complex numbers are real.

Most epistemologists hold that knowledge entails belief. However, proponents of this claim rarely offer a positive argument in support of it. Rather, they tend to treat the view as obvious and assert that there are no convincing counterexamples. We find this strategy to be problematic. We do not find the standard view obvious, and moreover, we think there are cases in which it is intuitively plausible that a subject knows some proposition P without—or at least without determinately—believing that P. Accordingly, (...) we present five plausible examples of knowledge without (determinate) belief, and we present empirical evidence suggesting that our intuitions about these scenarios are not atypical.

Esta coletânea é um tributo a Peter Frederick Strawson pelo centenário de seu nascimento (1919-2019). Diferentemente de outras coletâneas, esta propõe colocar em relevo a interlocução de Strawson com a tradição filosófica. Em outras palavras, por um lado, queremos evidenciar as discussões que Strawson travou com os seus contemporâneos (Austin, Quine, Russell e Wittgenstein), e, por outro, a influência que recebeu e as críticas que dirigiu àqueles que o precederam na história da filosofia (Aristóteles, Descartes, Hume, Kant). Poderíamos ter enriquecido (...) a lista acima com o nome de muitos outros filósofos com os quais Strawson teve contato, mas julgamos que o trabalho ficaria bastante extenso. Por esse motivo, optamos por aqueles nomes mais significativos que figuram na construção da história intelectual de Strawson. O presente volume reúne nove capítulos que levam como título o nome de Strawson e do filósofo com o qual ele dialogou ao longo de suas obras. Essa opção na nomeação dos capítulos por si só já permite colocar em evidência os principais filósofos pelos quais Strawson se interessou e com os quais se confrontou ao longo de seu trabalho filosófico. Com exceção do capítulo sobre Wittgenstein, que é uma versão revisada de um texto publicado anteriormente, todos os outros capítulos são inéditos e foram escritos especialmente para esta coletânea. O volume inclui na abertura a tradução de “Um fragmento de autobiografia intelectual”, de P. F. Strawson. Quando elegemos como título desta obra, Strawson e a tradição filosófica, não estamos insinuando que Strawson é um historiador da filosofia e muito menos que se interesse por historiografia. O título desta obra apenas quer indicar que Strawson, por um lado, transita na história da filosofia com alguma facilidade, além de nutrir um grande apreço por ela e, por outro, que ele discute com os principais nomes da história da filosofia no que concerne aos temas de seu interesse. A sua proposta filosófica é alimentada e irrigada por esse conhecimento, o que lhe dá a possibilidade de assumir na maioria das vezes posições ponderadas e equilibradas acerca de temas complexos por ele tratados. ​ ISBN: 978-85-5696-689-6.

The Identity principle says that conditionals with the form 'If p, then p' are logical truths. Identity is overwhelmingly plausible, and has rarely been explicitly challenged. But a wide range of conditionals nonetheless invalidate it. I explain the problem, and argue that the culprit is the principle known as Import-Export, which we must thus reject. I then explore how we can reject Import-Export in a way that still makes sense of the intuitions that support it, arguing that the differences between (...) indicative and subjunctive conditionals play a key role in solving this puzzle.

The paper is an examination and critique of the philosophy of science fiction horror of seminal American horror, science fiction and fantasy writer H.P. Lovecraft (1890-1937). Lovecraft never directly offers a philosophy of science fiction horror. However, at different points in his essays and letters, he addresses genres he labels “interplanetary fiction”, “horror”, “supernatural horror”, and “weird fiction”, the last being a broad heading covering both supernatural fiction and science fiction. Taken together, a philosophy of science fiction horror emerges. Central (...) to this philosophy is the juxtaposition of the mysterious, unnatural and alien against a realistic background, in order to produce the emotion that Lovecraft calls “cosmic fear”. This background must not only be scientifically accurate, but must accurately portray human psychology, particularly when humans are faced with the weird and alien. It will be argued that Lovecraft’s prescriptions are overly restrictive and would rule out many legitimate works of science fiction horror art. However, he provides useful insights into the genre.

Among our conscious states are conscious thoughts. The question at the center of the recent growing literature on cognitive phenomenology is this: In consciously thinking P, is there thereby any phenomenology—is there something it’s like? One way of clarifying the question is to say that it concerns whether there is any proprietary phenomenology associated with conscious thought. Is there any phenomenology due to thinking, as opposed to phenomenology that is due to some co-occurring sensation or mental image? In this paper (...) we will present two arguments that a “yes” answer to this question of cognitive phenomenology can be obtained via appeal to the HOT theory of consciousness, especially the version articulated and defended by David Rosenthal.

The contrast between the strategies of research employed in reductionism and holism masks a radical contradiction between two different scientific philosophies. We concentrate in particular on an analysis of the key philosophical issues which give structure to holistic thought. A first (non-exhaustive) analysis of the philosophical tradition will dwell upon: a) the theory of emergence: each level of organisation is characterised by properties whose laws cannot be deduced from the laws of the inferior levels of organisation (Engels, Morgan); b) clarification (...) of the relations between the “whole” and the “parts” (Woodger, Needham); c) the ontological or epistemological nature of the emergent properties; are they a phenomenological reality or solely an artefact of the state of our knowledge? (Pepper, Henle, Hempel and Oppenheim); d) the proposition of the holistic theoretical and methodological model ( Novikoff, Feibleman). I then go on to examine the differences that exist between the reductionist and the holistic approaches at various levels of analysis: that is to say, the differences which affect their ontologies, methodologies and epistemologies respectively. I attempt to understand the spirit of a holistic approach to ecology by analyzing the major work of E.P. Odum Fundamentals of ecology (1953, 1959, 1971). I set forward what might be meant by the “holistic approach”, which is implicated in all the different levels of organisation at which the problem of “complexity” is debated. Ecology presents itself as an “holistic science” and Odum’s book offers a vision of the world which dates far back in the history of philosophy. By looking at the three different editions of this fundamental text on ecology, we may become aware of the evolution of Odum’s thought. In fact, only in the third and last edition is there a conscious appropriation of the holistic approach (by using the theoretical models of Feibleman who, for his part, refers to Novikoff). However, even when formally referring to the theory of emergence (that is to say the ontological nucleus of every holistic approach), Odum’s systemic analysis presents the same logical errors, which push him back into the reductionist domain. Above all, in his examination of the main concepts of “population”, “community” and “ecosystem”, there is a misunderstanding of the profound difference between “collective properties” and “emergent properties”. Moreover, the cybernetic models of Odum’s systemic analysis (introduced into ecology by Margalef), allowed him to vastly oversimplify his methodological task: in fact, neither how many levels nor which levels of organization are fundamental for the study of each individual level is clearly marked. Finally, Odum analyses the ecosystem as composed of energetic flux and cycles of matter, referring to the trophic-dynamic vision of Lindeman. That is to say, in my opinion, he juxtaposes a reductionistic methodology and epistemology to an holistic ontology. (shrink)

I open my eyes and see that the lemon before me is yellow. States like this—states of seeing that $p$ —appear to be visual perceptual states, in some sense. They also appear to be propositional attitudes (and so states with propositional representational contents). It might seem, then, like a view of perceptual experience on which experiences have propositional representational contents—a Propositional View—has to be the correct sort of view for states of seeing that $p$ . And thus we can’t sustain (...) fully general non-Propositional but Representational, or Relational Views of experience. But despite what we might initially be inclined to think when reflecting upon the apparent features of states of seeing that $p$ , a non-propositional view of seeing that $p$ is, I argue, perfectly intelligible.

Most of our memories are inferential, so says Sven Bernecker in Memory: A Philosophical Study. I show that his account of inferentially remembering that p is too strong. A revision of the account that avoids the difficulty is proposed. Since inferential memory that p is memory that q (a proposition distinct from p) with an admixture of inference from one’s memory that q and a true thought one has that r, its analysis presupposes an adequate account of the (presumably non-inferential) (...) memory that q. Bernecker’s account of non-inferentially remembering that is shown to be inadequate. A remedy lies in strengthening the account by requiring the rememberer to have had prima facie justification to believe that q, any defeaters of which were misleading. (shrink)

According to Helen Longino, objectivity is necessarily social as it depends on critical interactions in com- munity. Justin Biddle argues that Longino’s account presupposes individuals that are completely open to any criticism; as such individuals are in principle able to criticise their beliefs on their own, Longino’s account is not really social. In the first part of my paper I argue that even for completely open individuals, criticism for maintaining objectivity is only possible in community. In the second part (...) I question Biddle’s interpretation of Longino’s conception of the individual. I conclude that objectivity as Longino describes it is necessarily social. (shrink)

One of Moore’s paradoxical sentence types is ‘P, but I believe ~P’. Mooreans have assumed that all tokens of that sentence type are absurd in some way: epistemically, pragmatically, semantically, or assertively. And then they proceed to debate what the absurdity really is. I argue that if one has the appropriate philosophical views, then one can rationally assert tokens of that sentence type, and one can be epistemically reasonable in the corresponding compound belief as well.

The influence of religious beliefs to several leading mathematicians in early Soviet years, especially among members of the Moscow Mathematical Society, had drawn the attention of militant Soviet marxists, as well as Soviet authorities. The issue has also drawn significant attention from scholars in the post-Soviet period. According to the currently prevailing interpretation, reported purges against Moscow mathematicians due to their religious inclination are the focal point of the relevant history. However, I maintain that historical data arguably offer reasons to (...) cast reasonable doubts on this interpretation. In this paper, by reviewing the relevant literature, I raise some methodological and philosophical concerns, in an attempt to contribute to a better understanding of the issue. I maintain that an efficient line of reasoning is to discuss issues in the context of their making, taking into consideration the specific features of each era’s culture. Thus, by focusing on P.A. Nekrasov’s case, I attempt to point to an alternative interpretation, in which the different treatment of religious inclined mathematicians by Soviet authorities is explained in the context of the ideological confrontation between two contrasting worldviews, as part of the ongoing class war in the several phases of Soviet history.

Pascal Engel défend explicitement le purisme (ou l’intellectualisme). Selon la version générale de cette thèse, les facteurs qui déterminent si une croyance est justifiée, ou si elle est une connaissance, ne concernent que la vérité. Ils sont totalement indépendants des désirs ou des préférences du sujet, ainsi que des conséquences pratiques potentielles du fait de posséder ces croyances. Dans son article « Pragmatic Encroachment and Epistemic Value » (2009), P. Engel concède que des facteurs pratiques peuvent déterminer la quantité de (...) données (ou la justification) dont on a besoin pour savoir ou croire, tout en maintenant que cela n’affecte pas le purisme épistémique (dans sa version évidentialiste) sur les notions de donnée ou de degré de justification. Mais cela ne revient-il pas tout simplement à concéder l’impurisme épistémique au moins à propos de la connaissance ou de la justification simpliciter des croyances ? Dans cet article, j’examine en détails la position de P. Engel. Je montre que, correctement comprise, elle est intégralement puriste. En considérant le principe connaissance-action, je soulève néanmoins un dilemme pour son approche, jetant ainsi un doute sur le potentiel qu’elle aurait à fournir une réponse puriste satisfaisante à l’argument fondamental motivant l’impurisme épistémique.

Information Theory, Evolution and The Origin ofLife: The Origin and Evolution of Life as a Digital Message: How Life Resembles a Computer, Second Edition. Hu- bert P. Yockey, 2005, Cambridge University Press, Cambridge: 400 pages, index; hardcover, US $60.00; ISBN: 0-521-80293-8. The reason that there are principles of biology that cannot be derived from the laws of physics and chemistry lies simply in the fact that the genetic information content of the genome for constructing even the simplest organisms is much (...) larger than the information content of these laws. Yockey in his previous book (1992, 335) In this new book, Information Theory, Evolution and The Origin ofLife, Hubert Yockey points out that the digital, segregated, and linear character of the genetic information system has a fundamental significance. If inheritance would blend and not segregate, Darwinian evolution would not occur. If inheritance would be analog, instead of digital, evolution would be also impossible, because it would be impossible to remove the effect of noise. In this way, life is guided by information, and so information is a central concept in molecular biology. The author presents a picture of how the main concepts of the genetic code were developed. He was able to show that despite Francis Crick's belief that the Central Dogma is only a hypothesis, the Central Dogma of Francis Crick is a mathematical consequence of the redundant nature of the genetic code. The redundancy arises from the fact that the DNA and mRNA alphabet is formed by triplets of 4 nucleotides, and so the number of letters (triplets) is 64, whereas the proteome alphabet has only 20 letters (20 amino acids), and so the translation from the larger alphabet to the smaller one is necessarily redundant. Except for Tryptohan and Methionine, all amino acids are coded by more than one triplet, therefore, it is undecidable which source code letter was actually sent from mRNA. This proof has a corollary telling that there are no such mathematical constraints for protein-protein communication. With this clarification, Yockey contributes to diminishing the widespread confusion related to such a central concept like the Central Dogma. Thus the Central Dogma prohibits the origin of life "proteins first." Proteins can not be generated by "self-organization." Understanding this property of the Central Dogma will have a serious impact on research on the origin of life. (shrink)

John P. Burgess kritisiert Kurt Gödels Begriff der mathematischen oder rationalen Anschauung und erläutert, warum heuristische Intuition dasselbe leistet wie rationale Anschauung, aber ganz ohne ontologisch überflüssige Vorannahmen auskommt. Laut Burgess müsste Gödel einen Unterschied zwischen rationaler Anschauung und so etwas wie mathematischer Ahnung, aufzeigen können, die auf unbewusster Induktion oder Analogie beruht und eine heuristische Funktion bei der Rechtfertigung mathematischer Aussagen einnimmt. Nur, wozu benötigen wir eine solche Annahme? Reicht es nicht, wenn die mathematische Intuition als Heuristik funktioniert? Für (...) Gödel sind Mengen Extensionen von Begriffen und er beharrt beispielsweise auf dem ontologischen Objektstatus von Mengen, weil Denken für ihn einen Input benötigt, den es selbst nicht zu liefern im Stande ist. Im Falle der mathematischen Anschauung darf dieser Input allerdings nicht subjektiv kontingent sein, wenn es sich um objektiv gültige Theorien handeln soll. (Zudem vertritt Gödel eine Korrespondenztheorie der Wahrheit.) Der Begriff der heuristischen Intuition, den Burgess expliziert, stammt hingegen nicht zuletzt aus der kognitiven Psychologie, der bei der Verarbeitung impliziter, also unbewusster Informationen ansetzt und so das menschliche Vermögen erklärt, Entscheidungen und Urteile zu fällen, ohne sich der Urteilsgrundlagen bewusst zu sein. Über den ontologischen oder erkenntnistheoretischen Status dieser Urteilsgrundlagen sagen diese Theorien nichts aus. Sie könnten auch subjektiv kontingent zustande gekommen sein. Ihr normativer Anspruch ergibt sich lediglich aus „dem Funktionieren“, nicht daraus, dass es sich um Gesetze des Wahrseins handelt. (shrink)

Standard linguistic analysis of syntax uses the T-model. This model requires the ordering: D-structure > S-structure > LF, where D-structure is the sentences deep structure, S-structure is its surface structure, and LF is its logical form. Between each of these representations there is movement which alters the order of the constituent words; movement is achieved using the principles and parameters of syntactic theory. Psychological analysis of sentence production is usually either serial or connectionist. Psychological serial models do not accommodate the (...) T-model immediately so that here a new model called the P-model is introduced. The P-model is different from previous linguistic and psychological models. Here it is argued that the LF representation should be replaced by a variant of Frege'sA three qualities (sense, reference, and force), called the FregeA representation or F-representation. In the F-representation the order of elements is not necessarily the same as that in LF and it is suggested that the correct ordering is: F-representation > D-structure > S-structure. This ordering appears to lead to a more natural view of sentence production and processing. Within this framework movement originates as the outcome of emphasis applied to the sentence. The requirement that the F-representation precedes the D-structure needs a picture of the particular principles and parameters which pertain to movement of words between representations. In general this would imply that there is a preferred or optimal ordering of the symbolic string in the F-representation. The standard ordering is retained because the general way of producing such an optimal ordering is unclear. In this case it is possible to produce an analysis of movement between LF and D-structure similar to the usual analysis of movement between S-structure and LF. The necessity of analyzing corrupted data suggests that a maximal amount of information about a language's grammar and lexicon is stored. (shrink)

Les recherches menées dans le champ de la psychologie morale par Larry P. Nucci et Elliot Turiel conduisent à identifier le domaine moral avec le domaine des jugements prescriptifs concernant la manière dont nous devons nous comporter à l’égard des autres personnes. Ces travaux empiriques pourraient apporter du crédit aux propositions normatives du philosophe Ruwen Ogien qui défend une conception minimaliste de l’éthique. L’éthique minimale exclut en particulier le rapport à soi du domaine moral. À mon avis cependant, ces travaux (...) de psychologie morale ne permettent pas du tout d’affirmer que nous sommes, empiriquement parlant, des minimalistes moraux. Les résultats des recherches de Nucci et Turiel montrent que les personnes considèrent intuitivement que le domaine personnel – le domaine des actions qui affectent prioritairement l’agent lui-même – doit échapper au contrôle ou à l’interférence des autres personnes. Mais affirmer que c’est l’agent lui-même qui possède l’autorité légitime de décider dans le domaine personnel ne signifie pas que tout ce qu’il y fait soit moralement indifférent. (shrink)

Le XI.ème Congrès International de Philosophie Médiévale de la Société Internationale pour l’Étude de la Philosophie Médiévale (S.I.E.P.M..) s’est déroulé à Porto (Portugal), du 26 au 30 août 2002, sous le thème général: Intellect et Imagination dans la Philosophie Médiévale. A partir des héritages platonicien, aristotélicien, stoïcien, ou néo-platonicien (dans leurs variantes grecques, latines, arabes, juives), la conceptualisation et la problématisation de l’imagination et de l’intellect, ou même des facultés de l’âme en général, apparaissaient comme une ouverture possible pour aborder (...) les principaux points de la pensée médiévale. Les Actes du congrès montrent que « imagination » et « intellect » sont porteurs d’une richesse philosophique extraordinaire dans l’économie de la philosophie médiévale et de la constitution de ses spécificités historiques. Dans sa signification la plus large, la théorisation de ces deux facultés de l’âme permet de dédoubler le débat en au moins six grands domaines: — la relation avec le sensible, où la fantaisie/l’imagination joue le rôle de médiation dans la perception du monde et dans la constitution de la connaissance ; — la réflexion sur l’acte de connaître et la découverte de soi en tant que sujet de pensée ; — la position dans la nature, dans le cosmos, et dans le temps de celui qui pense et qui connaît par les sens externes, internes et par l’intellect ; — la recherche d’un fondement pour la connaissance et l’action, par la possibilité du dépassement de la distante proximité du transcendant, de l’absolu, de la vérité et du bien ; — la réalisation de la félicité en tant qu’objectif ultime, de même que la découverte d’une tendance au dépassement actif ou mystique de toutes les limites naturelles et des facultés de l’âme ; — la constitution de théories de l’image, sensible ou intellectuelle, et de ses fonctions. Les 3 volumes d’Actes incluent les 16 leçons plénières et 112 communications, ainsi que les index correspondants (manuscrits ; noms anciens et médiévaux ; noms modernes ; auteurs). Le volume IV des Actes, contenant 39 communications et des index, est publié par la revue " Mediaevalia. Textos e Estudos ", du Gabinete de Filosofia Medieval de l’Universidade do Porto (volume 23, de 2004). Ouvrage publié avec l’appui de l’Universidade do Porto, de la Faculdade de Letras da U.P., du Departamento de Filosofia - F.L.U.P. et de la Fundação para a Ciência e a Tecnologia (Portugal).

The reason ability of considering time as a fuzzy concept is demonstrated in [7],[8]. One of the major questions which arise here is the new definitions of Complexity Classes. In [1],[2],…,[11] we show why we should consider time a fuzzy concept. It is noticeable to mention that that there were many attempts to consider time as a Fuzzy concept, in Philosophy, Mathematics and later in Physics but mostly based on the personal intuition of the authors or as a style of (...) Fuzzifying different various of the concepts. Consequently, fuzzifying time doesn’t go to be popular. In the new attempts we are trying to show why we are somewhat forced to consider time as a Fuzzy concept. It is mostly based on the “Unexpected Hanging Paradox” introduced by a Swedish Mathematician Lennart Ekbom. Our question is:” what will be the impact of it in Theory of Computation and Physics?”. Here, we discuss about the impact of fuzzifying time on Theory of Computation. (shrink)

Abstract The Theory of Computation in its existed form is based on Church –Turing Thesis. Throughout this paper, we show that the Turing computation model of this theory leads us to a contradiction. In brief, by applying a well-known paradox (Unexpected hanging paradox) we show a contradiction in the Theory when we consider the Turing model as our Computation model.

I present a counterexample to the claim that it is never true to say "I falsely believe that so-and-so." .
