The present study was motivated by the hypothesis that inputs from internal states in obsessive–compulsive individuals are attenuated, which could be one source of the pervasive doubting and checking in OCD. Participants who were high or low in OC tendencies were asked to produce specific levels of muscle tension with and without biofeedback, and their accuracy in producing the required muscle tension levels was assessed. As predicted, high OC participants performed more poorly than low OC participants on this task when (...) biofeedback was not available. When biofeedback was provided, the difference between the groups was eliminated, and withdrawing the monitor again reversed this effect. Finally, when given the opportunity, high OC participants were more likely than low OC participants to request biofeedback. These results suggest that doubt in OCD may be grounded in a real and general deficiency in accessing internal states. (shrink)

Spinoza is commonly perceived as the great metaphysician of coherence. The Euclidean manner in which he presented his philosophy in the _Ethics _has led readers to assume they are facing a strict and consistent philosophical system that necessarily follows from itself. As opposed to the prevailing understanding of Spinoza and his work, _The Role of Contradictions in Spinoza's Philosophy_ explores an array of profound and pervasive contradictions in Spinoza’s system and argues they are deliberate and constitutive of his philosophical thinking (...) and the notion of God at its heart. Relying on a meticulous and careful reading of the _Theological-Political Treatise_ and the _Ethics_, this book reconstructs Spinoza's philosophy of contradictions as a key to the ascending three degrees of knowledge leading to the _Amor intellectualis Dei_. Offering an exciting and clearly-argued interpretation of Spinoza’s philosophy, this book will interest students and scholars of modern philosophy and philosophy of religion, as well as Jewish studies. Yuval Jobani is Assistant Professor at the Department of Hebrew Culture Studies and the School of Education at Tel-Aviv University. (shrink)

Dreams are a remarkable experiment in psychology and neuroscience, conducted every night in every sleeping person. They show that the human brain, disconnected from the environment, can generate an entire world of conscious experiences by itself. Content analysis and developmental studies have promoted understanding of dream phenomenology. In parallel, brain lesion studies, functional imaging and neurophysiology have advanced current knowledge of the neural basis of dreaming. It is now possible to start integrating these two strands of research to address fundamental (...) questions that dreams pose for cognitive neuroscience: how conscious experiences in sleep relate to underlying brain activity; why the dreamer is largely disconnected from the environment; and whether dreaming is more closely related to mental imagery or to perception.

Wittgenstein on the Human Spirit provides a new understanding of Wittgenstein’s discourse as an insightful philosophy of culture, pursued through self-reflection. It offers an edifying perspective on the conceptual underpinnings of culture as a shared expressive spiritual form of life. The ideas investigated in it are highly relevant for discussions in philosophy, aesthetics, anthropology, and cultural studies. The book embraces three studies: The Spirit of Jews, The Spirits of Culture and Civilization, and The Common Spirit of Human Beings. The first (...) discusses Wittgenstein's remarks about Jews, focusing on their place within his philosophical thinking, self-reflection, and European discourse about culture and Jews. It shows how overcoming the anti-Semitic attitude implicit in them set off the major change in his philosophy. The second discusses Wittgenstein’s reflections on the “deterioration of culture” in the modern period, showing how they are related to his remarks about following rules. The third discusses Wittgenstein’s insights regarding the symbolic nature of myth, magic and religion. It suggests that modern human beings and those of ancient cultures possess a common expressive spiritual nature. This enables us to understand expressive practices in other cultures without interpretation. Nonetheless religious belief during the modern period is problematic. (shrink)

Currently, the dominant enforcement paradigm is based on the idea that states deal with 'bad people' - or those pursuing their own self-interests - with laws that exact a price for misbehavior through sanctions and punishment. At the same time, by contrast, behavioral ethics posits that 'good people' are guided by cognitive processes and biases that enable them to bend the laws within the confines of their conscience. In this illuminating book, Yuval Feldman analyzes these paradigms and provides a (...) broad theoretical and empirical comparison of traditional and non-traditional enforcement mechanisms to advance our understanding of how states can better deal with misdeeds committed by normative citizens blinded by cognitive biases regarding their own ethicality. By bridging the gap between new findings of behavioral ethics and traditional methods used to modify behavior, Feldman proposes a 'law of good people' that should be read by scholars and policymakers around the world.

The idea that the present is "ontologically privileged" can be traced back to texts as early as St. Augustine's Confessions and Aristotle's Physics. The issue of the ontological status of tense continues to set the agenda in contemporary philosophy of time, which is dominated by two views. Proponents of the Tenseless View argue that all events are, in the timeless sense of 'are', equally real. Defenders of the rival Tensed View maintain that only present events are real, and that the (...) reality of tense is the essence of time. The first two chapters of the dissertation are devoted to the presentation and study of these, on the face of it, mutually exclusive and jointly exhaustive metaphysical theories of time. The aim of the analysis is, on the one hand, to highlight the insights that are motivating these theories and that are captured by them; on the other, it is to establish that neither theory can be squared with features of the language which it presupposes, and that, therefore, both have to be rejected. ;Uncovering and undermining the metaphysical prejudices shared by both views, in particular, the supposition that 'Real or not?' is the right question to pose with respect to tense, paves the way to the central thesis that occupies the second part of the dissertation. Crudely put, it is that the ingredients for the construction of a philosophically adequate conception of time are found, not among the products of metaphysical doctrines, but in the everyday uses we make of temporal notions. In the third chapter, a discussion of the indispensability of contexts for the use of temporal terms constitutes the beginning of the argument in support of this thesis. In chapter four an analysis of the philosophical role of tense-based biases in our attitudes concludes the argument, and yields a list of the main tools with which one can construct a conception of time out of everyday situations and the language employed in them. Chapter five consists of a demonstration of the application of these tools for the elucidation of notions such as 'the openness of the future', 'the fixity of the past' and 'time's passage' . Among the conclusions of this discussion is the suggestion that notions with which to further develop and enrich our conception of time may be obtained by the formation and participation in practices created for this end.

The hematopoietic system consists of more than ten differentiated cell types, all of which are derived from a single type of hematopoietic stem cell. The accessibility and interest of this system have made it a model for understanding normal and abnormal differentiation of mammalian cells. Newer techniques have generated a mass of data that requires integrative approaches for analysis and interpretation. The traditional view of the differentiation program holds that a small number of regulators are involved in each stage of (...) cell specification. However, this may not be the case. Recent analyses have shown that almost all substantial subsets of genes, including the set of broadly expressed transcription factors, are expressed in patterns that are unique for each lineage. Further, much of this difference between lineages can be captured in two‐dimensional graphs. Understanding the biologic significance, mechanisms and constraints underlying these differences is a challenge for experimentalists and computational biologists alike.

The conceptual history of Bildung, the German term for self-formation, encapsulates the ethical revolution of modern German thought, associated with the Kantian moment and its aftermath. Reshaped in modernity to respond to a post-Kantian, critical sensibility, the modern term emphasizes the reflexive, active process of self-formation, in contrast with the medieval theological sensibility which emphasized the receptive imprint of the image of God. In this article, I unpack Moses Mendelsohn’s idiosyncratic notion of Bildung. I show that what is unique, indeed, (...) singular in Mendelssohn’s notion of Bildung is the way it merges the traditional, theological notion with the modern one. For Mendelssohn, to imitate God is to come to value one’s contingent being. The imitation of the ideal, the most perfect, is tantamount to embracing the perfectible, and the process of perfection or self-actualization.

Is pure mathematics - arithmetic as well as geometry - reducible to formal logic? Russell answered in the affirmative, considering this so significant as to constitute a fatal blow to Kant's synthetic-apriori philosophy of mathematics. But either pure arithmetic and pure geometry include the full, extra-logical content of their unique axioms and hence their unique theorems, or they do not. If they do, then this reductionism is trivially unsound. It they do not - if they include only the logic of (...) demonstration and exclude everything else - then it is trivially true, but insignificant. In fact this would accomplish no reduction at all, but rather a harmless formalization. (shrink)

Dolev's ambitious project is to show that the traditional debate in the philosophy of time between the so-called ‘tensed’ and ‘tenseless’ theorists is not a sustainable one. The key to the negative portion argument is that both the tensed and tenseless view of time can be understood only from within their respective ontological frameworks. Moreover, that there is only really an appearance of understanding within these frameworks, since neither framework furnishes us with the wherewithal to genuinely understand temporal language. Moving (...) past these frameworks is the goal Dolev sets us. The positive aspect of the text tries to teach us how to transcend this merely ontological dispute and engage in phenomenological considerations of time itself. The conclusion to the positive project is that we cannot postulate an adequate metaphysical system of time, though we can understand what time is if we treat it as the time of our experiences in everyday life.The prospect that we might be able to move past the existing debate into fresh philosophical terrain is exciting. But I am not quite persuaded by the arguments that are intended to motivate the move to pastures new. First, on occasion Dolev seems to slightly …. (shrink)

Most solutions to the skeptical paradox about justified belief assume closure for justification, since the rejection of closure is widely regarded as a non-starter. I argue that the rejection of closure is not a non-starter, and that its problems are no greater than the problems associated with the more standard anti-skeptical strategies. I do this by sketching a simple version of the unpopular strategy and rebutting the three best objections to it. The general upshot for theories of justification is that (...) it is not a constraint on such theories that we must somehow have justification to believe that we are not massively deceived. (shrink)

What intelligent person has never pondered the meaning of life? For Yuval Lurie, this is more than a puzzling philosophical question; it is a journey, and in this book he takes readers on a search that ranges from ancient quests for the purpose of life to the ruminations of postmodern thinkers on meaning. He shows that the question about the meaning of life expresses philosophical puzzlement regarding life in general as well as personal concern about one’s own life in (...) particular. Lurie traces the emergence of this question as a modern philosophical quandary, riddled with shifts and turns that have arisen over the years in response to it. _Tracking the Meaning of Life _is written as a critical philosophical investigation stretching over several traditions, such as analytic philosophy, phenomenology, and existentialism. It maps out a journey that explores pivotal responses to this question, drawing especially on the thought of Tolstoy, Wittgenstein, Sartre, and Camus and exploring in depth the insights these thinkers offer regarding their own difficulties concerning the meaning of life. In the book’s four sections, Lurie discusses Tolstoy’s challenge to experience the religious and transcendental meaning of life by choosing a simple, hardworking existence; Wittgenstein’s focus on ethics and discovering the sense of the world, his conclusion that the question of the meaning of life makes no sense, and his turning to experience the mystical aspect of the world; Sartre’s positing of freedom as the basis of human life, stipulating a personal answer to the question of the meaning of life; and Camus’ view of the absurdity of life, unalleviated by any personal meaning. Guided by these views, Lurie imparts new insight to ideas that underlie our concern with life’s meaning, such as the difference between attitudes toward life and beliefs and opinions about life, the meaning of words versus the meaning of events, shared meanings versus personal meanings, and the link between ethics and personal identity. _Tracking the Meaning of Life_ is no mere dry philosophical study but a journey that dramatically illustrates the poignancy of the quest for meaning, showing that along the way it gradually becomes more obvious how personal meaning may be found in the pulsations of everyday life. The book offers stimulating reading not only for scholars in philosophy but also for general readers who wish to see how their personal concerns are echoed in modern philosophical thought. More than a description of a journey, it is a map to anxieties and puzzlements we all face, pointing to ideas that can guide readers on their own search for meaning. (shrink)

A well known skeptical paradox rests on the claim that we lack warrant to believe that we are not brains in a vat. The argument for that claim is the apparent impossibility of any evidence or argument that we are not BIVs. Many contemporary philosophers resist this argument by insisting that we have a sort of warrant for believing that we are not BIVs that does not require having any evidence or argument. I call this view ‘New Rationalism’. I argue (...) that New Rationalists are committed to there being some evidence or argument for believing that we are not BIVs anyway. Therefore, New Rationalism, since its appeal is that it purportedly avoids the problematic commitment to such evidence or argument, undermines its own appeal. We cannot avoid the difficult work of coming up with evidence or argument by positing some permissive sort of warrant. (shrink)

In this paper I argue that physics is, always was, and probably always will be voiceless with respect to tense and passage, and that, therefore, if, as I believe, tense and passage are the essence of time, physics’ contribution to our understanding of time can only be limited. The argument, in a nutshell, is that if "physics has no possibility of expression for the Now", to quote Einstein, then it cannot add anything to the study of tense and passage, and (...) specifically, cannot add anything to the debate between deniers and affirmers of the existence or reality of tense and passage. Since relativity theory did not equip physics with a new language with which to speak of tense and passage, I draw the further conclusion that relativity theory has not generated the revolution to our conception of time that is attributed to it. In the last section I discuss the motivations behind the continued but misguided attempts to integrate tense into a relativistic setting, and assess the manners in which relativity theory has nevertheless enhanced, albeit indirectly, our understanding of tense and passage.

In this paper I claim that as bitter as the eternalist/presentist rivalry is, as far as both camps are concerned, a third position—which I defend—is more disturbing. The reason is that what eternalists and presentists agree on is more fundamental than what they disagree about. They agree that time carves, to use Orilia’s term, “ontological inventories.” This in a way answers the “fundamental question”—what is time? They disagree about the contents of the inventories, but that, I suggest, is a secondary (...) issue. Thus, an argument against what they agree about would be more detrimental to their joint project—analyzing tense in ontological terms—than the internal disagreement they are engaged in. I develop this thesis by responding to Orilia’s paper “Two Metaphysical Perspectives on the Duration of the Present”. I criticize the specialized use Orilia makes of the notion of an “ontological inventory” in the context of the metaphysics of time, but also Quine’s approach to ontology, on which Orilia’s account relies. The gist of my criticism is that it is question begging to rely on the notion of an “ontological inventory” for giving content to the presentism/eternalism debate, and for arguing that there can’t be an alternative.

Someone who intentionally violates the rules of a game is not playing the game.2. In many cases, players intentionally violate the rules as part of playing the game.The problem has a normative counterpart:1’. In normal cases, it is wrong for a player to intentionally violate the rules of the game.2’. In many normal cases, it is not wrong (...) for a player to intentionally violate the rules of the game.According to both formalism and informalism, the rules of the game include the formal rules of the game. Both traditional positions avoid the incompatibility problems by rejecting 1 and 1'. Practiceism rejects 2 and 2’: it maintains that the rules are the rules manifested in playing the game, not the formal rules.Practiceism presents two theses: (... (shrink)

It starts with conceptual clarifications of the notions of citizenship, belonging and intersectionality and then turns to examine contemporary politics of belonging in contemporary Britain, focusing on the current debate on the ‘death of multiculturalism’ and on ‘social cohesion’. It illustrates how the use of civic and democratic values as signifiers of belonging can end up as exclusionary, rather (...) than inclusionary in that discourse. (shrink)

For millennia, war was viewed as a supreme test. In the period 1750-1850 war became much more than a test: it became a secular revelation. This new understanding of war as revelation completely transformed Western war culture, revolutionizing politics, the personal experience of war, the status of common soldiers, and the tenets of military theory.

Growing recognition in both the psychological and management literature of the concept of “good people” has caused a paradigm shift in our understanding of wrongful behavior: Wrongdoings that were previously assumed to be based on conscious choice—that is, deliberate decisions—are often the product of intuitive processes that prevent people from recognizing the wrongfulness of their behavior. Several leading scholars have dubbed this process as an ethical “blind spot.” This study explores the main implications of the good people paradigm on the (...) regulation of employees’ conflicts of interest. In two experiments, we examined the efficacy of traditional deterrence- and morality-based interventions in encouraging people to maintain their professional integrity and objectivity at the cost of their own self-interest. Results demonstrate that while the manipulated conflict was likely to “corrupt” people under intuitive/automatic mindset, explicit/deliberative mechanisms had a much larger constraining effect overall on participants’ judgment than did implicit measures, with no differences between deterrence and morality. The findings demonstrate how little is needed to compromise the employees’ ethical integrity, but they also suggest that a modest explicit/deliberative intervention can easily prevent much of the wrongdoing that may otherwise result.

For most of the vast span of human history, economic growth was all but nonexistent. Then, about two centuries ago, some nations began to emerge from this epoch of economic stagnation, experiencing sustained economic growth that led to significant increases in standards of living and profoundly altered the level and distribution of wealth, population, education, and health across the globe. The question ever since has been--why? This is the first book to put forward a unified theory of economic growth that (...) accounts for the entire growth process, from the dawn of civilization to today. Oded Galor, who founded the field of unified growth theory, identifies the historical and prehistorical forces behind the differential transition timing from stagnation to growth and the emergence of income disparity around the world. Galor shows how the interaction between technological progress and population ultimately raised the importance of education in coping with the rapidly changing technological environment, brought about significant reduction in fertility rates, and enabled some economies to devote greater resources toward a steady increase in per capita income, paving the way for sustained economic growth. Presents a unified theory of economic growth from the dawn of civilization to today Explains the worldwide disparities in living standards and population we see today Provides a comprehensive overview of the three phases of the development process Analyzes the Malthusian theory and its empirical support Examines theories of demographic transition and their empirical significance Explores the interaction between economic development and human evolution.

Wittgenstein's remarks on the nature of culture presuppose a view according to which there is an important difference between culture and civilization. This view aligns his thinking to that of the Romantic tradition in philosophy. It also leads him to perceive ?the disappearance of a culture? in our time. In many of his remarks on art and certain artists he expresses this view by attempting to clarify the different ways in which the spirit of man is manifested in modern times (...) (in arts, science, and industry) as opposed to how it is manifested in an age of culture. This article undertakes to describe and explain the remarks which lead him to this view. It then considers whether Wittgenstein was, in fact, correct in his evaluation regarding the disappearance of a culture. (shrink)

The conclusion reflects on the limitations of the proposed typology and identifies further avenues for the philosophical study of Hebrew secularism. (shrink)

Human beings are a cultural species. This predicament enables them to take on many different cultural identities, all of which transcend the bounds of natural behavior of other species. To contemplate this predicament through philosophy is to reflect on such questions as, What makes cultural forms of life possible? What is encompassed in them? What lies at their core? What distinguishes them from natural forms of life? What brings them about, sustains, and causes them to change? Philosophical answers to these (...) questions predate abstract ways of thinking, as they are sometimes embedded in ancient mythical and religious narratives. Such is the story told in the first three chapters of the book of Genesis in the Bible, revealing how human beings became the cultural beings that they are. This study suggests how that ancient and most celebrated story in the literature of the West may be read as harboring insightful philosophical observations on the cultural nature of human beings. It first focuses on the very concept of cultural forms of life, revealing its complicated conceptual links to natural forms of life. It then offers an interpretive framework for reading mythical, symbolic narratives. Using these ideas, it provides a philosophical reading of the Biblical narrative, disclosing it to harbor a metaphysically oriented conception of nature and two insightful philosophical overviews of the cultural nature of human beings. Both overviews endow human beings with an ability to manipulate nature, but in different ways: the first by subjugating parcels of nature to human will; the second by subjugating human beings themselves to a value-laden conception of things and ethical forms of life. Thus, human beings are portrayed as natural creatures possessed of a cultural nature that enables them to transform nature and recreate themselves through their unique cultural predicament. (shrink)

Keratins are a family of intermediate filaments that serve various crucial roles in skin physiology. For mammalian skin to function properly, and to produce epidermal and hair keratins that are optimally adapted for their environment, it is critical that keratin gene and protein expression are stringently controlled. Given that the skin is not only targeted by multiple hormones, but also constitutes a veritable peripheral endocrine organ, it is not surprizing that intracutaneous keratin expression is underlined by tight endocrine controls. These (...) controls encompass thyroid hormones, steroid hormones such as glucocorticoids (GCs), retinoic acid (RA) and vitamin D, and several neuroendocrine mediators. Here, we review why a better understanding of the endocrine controls of keratin expression is not only required for an improved insight into normal human skin and hair function, but may also open new therapeutic avenues in a wide range of skin and hair diseases.

In “The Blessing of Departure—Exchange of Populated Territories The Lieberman Plan as anExercise in Demographic Transformation,” Prof. Timothy Waters offers a strong endorsement of the right of ethnic majorities within a state to redefine their state's boundaries in ways consistent with the majority's right to self-determination and to opt out of a political union with minority groups, regardless of the latter's' political preferences. Applied to the Israeli context, Waters concludes that parts of the Lieberman Plan—a plan advocating the redrawing of (...) Israel borders, inter alia, in ways which exclude some areas populated by Israeli citizens belonging to the Arab-Palestinian minority —does not run afoul of international law . This short response challenges two points that are central to Waters’s analysis. First, that the right to self-determination of peoples—in particular, the right to external self-determination —is subject to temporal or contextual limitations. The right is fully applicable only in exceptional and formative moments in the life of a nation—e.g., during the formation of a new polity or the collapse of an existing political arrangement , and when states systematically fail to respect the basic interest of some of the groups that comprise its populace—i.e., in response to extraordinary situations of groups exclusion or oppression. Second, even if Waters is correct and an ongoing right to self-determination—including, a right to secede from existing states—is available to ethnic groups comprising diverse national societies, the invocation of such a right must necessarily be limited by other positive rules of international law designed to protect group and individual interests. Specifically, Waters’s concept of self-determination as a right of a preliminary nature, that overrides other human rights , is debatable. (shrink)
