Zeki and co-workers recently proposed that perception can best be described as locally distributed, asynchronous processes that each create a kind of microconsciousness, which condense into an experienced percept. The present article is aimed at extending this theory to metacognitive feelings. We present evidence that perceptual fluency—the subjective feeling of ease during perceptual processing—is based on speed of processing at different stages of the perceptual process. Specifically, detection of briefly presented stimuli was influenced by figure-ground contrast, but not by symmetry (...) or the font of the stimuli. Conversely, discrimination of these stimuli was influenced by whether they were symmetric and by the font they were presented in , but not by figure-ground contrast. Both tasks however were related with the subjective experience of fluency . We conclude that subjective fluency is the conscious phenomenal correlate of different processing stages in visual perception. (shrink)

Perceptual fluency is the subjective experience of ease with which an incoming stimulus is processed. Although perceptual fluency is assessed by speed of processing, it remains unclear how objective speed is related to subjective experiences of fluency. We present evidence that speed at different stages of the perceptual process contributes to perceptual fluency. In an experiment, figure-ground contrast influenced detection of briefly presented words, but not their identification at longer exposure durations. Conversely, font in which the word was written influenced (...) identification, but not detection. Both contrast and font influenced subjective fluency. These findings suggest that speed of processing at different stages condensed into a unified subjective experience of perceptual fluency. (shrink)

Pascal was a scientist and man of the world who came to be a passionately devout Christian. The fragments of his great defense of Christianity, left unfinished at his death in 1662, survive in the form of the Pensees. This series of brief, dramatic notes on his religious convictions are here translated into English. These thoughts expose Pascal's vision of the world and display powerful reasoning and a profound faith.

PREFACE When in the year 1940 I ventured a small volume under the title The Secret of Pascal, I honestly did not expect to write further on the topic. But circumstances ordered otherwise. The needs of Cambridge students and the difficulty, ...

People outside France have always wondered why analytical philosophy has had so little influence in this country, while it has gained currency in many other European countries, such as Germany and Italy, not to speak of Northern Europe, where the analytical tradition is strongly established. This can be explained only by a particular conjunction of historical, cultural, sociological and maybe economical factors, which it would be too long to detail here. If there are natural characters of nations, there is no (...) reason to believe that there are no philosophical characters of nations. As Hume said, the characters of nations can have physical as well as moral causes. As for the physical causes, everybody in Britain knows how insular the Continent can be. So if there is such a thing as French analytical philosophy, nobody will be surprised to learn that it is very insular. Before presenting some of the work done by French philosophers related to the analytical tradition, let me try to give what I take to be some of the moral causes of their insularity. (shrink)

Between 9th and 11th centuries, the geometrical transformations gave to the mathematicians a method more and more fertile, leading them to modify their modes of apprehension of the geometrical figures. This article aims to highlight al-Sijzī’s contribution to this change by setting two tasks: first, to precisely understand what al-Sijzī means by transformation ; and secondly, to give an account of his research on geometrical invariants, obtained by a variation of some elements of a figure. The use of transformations and (...) the search for invariants seem to be the two faces of the same tendency, that to break with an Euclidean manner to consider the figures in a way isolated and static for better exploiting the common properties which can link them. The article is completed by the edition and the translation of a small treatise devoted to invariants. Résumé En offrant une méthode de plus en plus féconde, les transformations géométriques conduisent les mathématiciens, entre les ix e et xi e siècles, à modifier leurs modes d’appréhension des figures géométriques. Le présent article voudrait mettre en évidence la contribution d’al-Sijzī à cette mutation en se fixant deux tâches: en premier lieu, comprendre précisément ce qu’al-Sijzī entend par transformation ; et en second lieu, rendre compte de ses recherches sur les invariants géométriques, obtenus en faisant varier certains éléments d’une figure. L’usage des transformations et la recherche d’invariants apparaissent comme les deux volets d’une même tendance, celle de rompre avec une manière euclidienne de considérer les figures de façon isolée et statique pour mieux exploiter les propriétés communes qui peuvent les unir. L’article s’achève par l’édition et la traduction d’un petit traité consacré à la mise en évidence d’invariants. (shrink)

Many think that Pascal’s Wager is a hopeless failure. A primary reason for this is because a number of challenging objections have been raised to the wager, including the “many gods” objection and the “mixed strategy” objection. We argue that both objections are formal, but not substantive, problems for the wager, and that they both fail for the same reason. We then respond to additional objections to the wager. We show how a version of Pascalian reasoning succeeds, giving us (...) a reason to pay special attention to the infinite consequences of our actions. (shrink)

Pascal’s wager has to face the many gods objection. The wager goes wrong when it asks us to chose between Christianity and atheism, as if there are no other options. Some have argued that we’re entitled to dismiss exotic, bizarre, or subjectively unappealing religions from the scope of the wager. But they have provided no satisfying justification for such a radical wager-saving dispensation. This paper fills that dialectical gap. It argues that some agents are blameless or even praiseworthy for (...) ignoring all but one religion as they face the wager. The argument leads us to multiple Pascals: a Jewish one, a Christian one, a Muslim one, and more. (shrink)

Is it reasonable to believe in God even in the absence of strong evidence that God exists? Pragmatic arguments for theism are designed to support belief even if one lacks evidence that theism is more likely than not. Jeff Jordan proposes that there is a sound version of the most well-known argument of this kind, Pascal's Wager, and explores the issues involved - in epistemology, the ethics of belief, decision theory, and theology.

In Pascal’s famous wager, he claims that the seeking non-believer can induce genuine religious belief in herself by joining a religious community and taking part in its rituals. This form of belief regulation is epistemologically puzzling: can we form beliefs in this way, and could such beliefs be rationally held? In the first half of the paper, we explain how the regimen could allow the seeking non-believer to regulate her religious beliefs by intervening on her evidence and epistemic standards. (...) In the second half of the paper, we argue that regulated religious beliefs can be rationally held. (shrink)

In a well-known paper, Nick Bostrom presents a confrontation between a fictionalised Blaise Pascal and a mysterious mugger. The mugger persuades Pascal to hand over his wallet by exploiting Pascal's commitment to expected utility maximisation. He does so by offering Pascal an astronomically high reward such that, despite Pascal's low credence in the mugger's truthfulness, the expected utility of accepting the mugging is higher than rejecting it. In this article, I present another sort of high (...) value, low credence mugging. This time, the mugger utilises research on existential risk and the long-term potential of humanity to exploit Pascal's expected-utility-maximising descendant. This mugging is more insidious than Bostrom's original as it relies on plausible facts about the long-term future, as well as realistic credences about how our everyday actions could, albeit with infinitesimally low likelihood, affect the future of humanity.

In part one of this book I argue for the conditional claim that if Christianity has at least a 50% epistemic probability, then it is rational to commit to living a Christian life (and irrational not to). This claim is supported by a contemporary version of Pascal's wager. In part two, I then proceed to argue that Christianity does have at least a 50% epistemic probability, by advancing versions of the cosmological argument, the fine-tuning argument, and historical arguments for (...) the plausibility of the resurrection (along with a few other relevant considerations). Assessments of the problem of evil and divine hiddenness are also given. Finally, in part three, I discuss the lives of three Christians from the 20th century (Dietrich Bonhoeffer, Jean Vanier, and Immaculee Ilibagiza) in an effort to illustrate how a life of Christian commitment is not just reasonable, but worth desiring as well--satisfying both the head and the heart.

Pascal’s Wager does not exist in a Platonic world of possible gods, abstract probabilities and arbitrary payoffs. Real decision-makers, such as Pascal’s “man of the world” of 1660, face a range of religious options they take to be serious, with fixed probabilities grounded in their evidence, and with utilities that are fixed quantities in actual minds. The many ingenious objections to the Wager dreamed up by philosophers do not apply in such a real decision matrix. In the situation (...) Pascal addresses, the Wager is a good bet. In the situation of a modern Western intellectual, the reasoning of the Wager is still powerful, though the range of options and the actions indicated are not the same as in Pascal’s day. (shrink)

One version of Pascal’s Wager says we should commit to, or cultivate belief in, whatever religion we think is most likely to bring us eternal joy. I pose a reductio for this version of the Wager. After exploring some ways the Pascalian might respond, the verdict is that it provides some reason to suspect that somewhere, somehow, the Wager goes wrong.

L'on montre: 1) que l'affirmation tschirnhausienne selon laquelle l'art de découvrir transforme notre nature en une nature quasi surhumaine qui semble assez participer de celle de Dieu, et en laquelle C. Thomasius avait subodoré un fort relent spinoziste, est explicable, et est effectivement expliquée par Tschirnhaus dans sa Medicina mentis, d'une façon qui ne saurait effaroucher un théologien orthodoxe; 2) que, malgré la modernité de certaines vues de Tschirnhaus relatives au rôle de l'expérience, cet auteur n'a pas perçu la véritable (...) fonction de la „confirmation" expérimentale, contrairement à ce qu'on admet fréquemment de nos jours; 3) pourquoi il convient de penser que c'est dans Spinoza que Tschirnhaus a puisé sa conception des définitions génétiques; 4) que, contrairement à l'opinion courante, ie manuscrit de la Mediana mentis a vraisemblablement été envoyé en Hollande en latin .

Most students of Tocqueville know of his remark, “There are three men with whom I live a little every day; they are Pascal, Montesquieu, and Rousseau.” In this paper I trace out the contours of Pascal’s influence upon Tocqueville’s understanding of the human condition and our appropriate response to it. Similar temperaments lead both Tocqueville and Pascal to emphasize human limitations and contingency, as Peter Lawler rightly emphasizes. Tocqueville and Pascal both emphasize mortality, ignorance of the (...) most important subjects, the effects of historical contingency on what we take to be human nature, and both represent the complex internal dynamic of human nature in terms of the interplay of “angel” and “brute.” The most important difference between them concerns their relative estimates of human power and the significance of human action. Whereas the motif of human weakness is fundamental for Pascal, Tocqueville repeatedly affirms that, under the right conditions, human beings are “powerful and free.” Beginning from Pascalian premises, and endeavoring to be more faithful to some of those premises than Pascal himself was, Tocqueville aims to illuminate the possibility of an amelioration of the human condition through a “new political science” that redeems the political realm without divinizing it. -/- .

Unlike other classical arguments for the existence of God, Pascal’s Wager provides a pragmatic rationale for theistic belief. Its most popular version says that it is rationally mandatory to choose a way of life that seeks to cultivate belief in God because this is the option of maximum expected utility. Despite its initial attractiveness, this long-standing argument has been subject to various criticisms by many philosophers. What is less discussed, however, is the rationality of this choice in situations where (...) the decision-makers are confronted with greater uncertainty. In this paper, I examine the imprecise version of Pascal’s Wager: those scenarios where an agent’s credence that God exists is imprecise or vague rather than precise. After introducing some technical background on imprecise probabilities, I apply five different principles for decision-making to two cases of state uncertainty. In the final part of the paper, I argue that it is not rationally permitted to include zero as the lower probability of God’s existence. Although the conditions for what makes an act uniquely optimal vary significantly across those principles, I also show how the option of wagering for God can defeat any mixed strategy under two distinct interpretations of salvation.

Included in this volume are fourteen of the fragments intended for Pascal's Jansenist-inspired defense of the Christian religion. Using the Chevalier edition, these are grouped to present a logical development of three themes, "The State of Man in Ignorance of God," "The Wager," and "The Christian Life." This translation closely follows the French text (cross-referenced with the paragraph numbers of the Brunschvicg edition) and does not conceal the fragmentary style of the original. Translated and edited by Arthur H. Beattie, (...) this volume also contains an introduction, a list of principal dates in the life of Pascal, and a bibliography. (shrink)

Perceptual fluency is the subjective experience of ease with which an incoming stimulus is processed. Although perceptual fluency is assessed by speed of processing, it remains unclear how objective speed is related to subjective experiences of fluency. We present evidence that speed at different stages of the perceptual process contributes to perceptual fluency. In an experiment, figure-ground contrast influenced detection of briefly presented words, but not their identification at longer exposure durations. Conversely, font in which the word was written influenced (...) identification, but not detection. Both contrast and font influenced subjective fluency.

I argue that a version of Pascal's Wager applies to the persistent vegetative state with sufficient force that it ought to part of advance directives.
