The tripartite model of militant extremist mind-set proposed by Stankov et al. (2010b) includes three components: War (justification of violent acts); God (extremist acts are moral because they are done in the name of God/Allah); and West (violence against Western countries is justified because they are perceived as evil). There is a lack of conceptual framework regarding psychological mechanism that underlie radicalization and extremism, and there is little evidence regarding risk factors for radicalization in the scientific literature. In the present (...) study, it is hypothesized that irrational beliefs and a constellation of personality factors are two possible psychological mechanisms that put adolescents in a vulnerable position and could influence them to develop an extremist mind-set. The sample consists in 295 Romanian adolescents, ages 15-18 years, and the mean age being 16.41. The present study was conducted in several schools from Bihor County located in the north-western part of Romania. Adolescents took part on a voluntary basis in the study after the written, informed consent was obtained from their parents. A confirmatory factor analysis (CFA) on the structure of Militant Extremist Mind-Set Scale confirmed the three-factor model of the extremist mind-set. Two confirmatory factor analyses were also conducted for the other two administered scales: CASI and Mini-IPIP. The results support the previous models for both subscales, including items loading on factors. SEM analysis was performed with AMOS 23 statistical package on a final sample size of 242 participants and there were no missing data. Fifth structural models were specified. The fifth model had adequate fit based on all three indices including the RMSEA (0.054), CFI (0.958), and SRMS (0.047). Global evaluation of self seems to be the only irrational belief that was somewhat related with the extremis mind-set, being part of it. Neuroticism was not identified as being a variable that could have a direct influence on mind-set extremism, or an indirect influence through personality. Religious adherence is a good predictor of extremist ideology. A global personality factor consisting in low Intellect/Imagination, low Extraversion and high Agreeableness seems to be a vulnerability factor that influences people to believe in extremist ideology.

The Irrational Augustine takes the notion of St Augustine as rigid and dogmatic Father of the Church and turns it on its head. Catherine Conybeare reads Augustine's earliest works to discover the anti-dogmatic Augustine, who values changeability and human interconnectedness and deplores social exclusion. The novelty of her book lies in taking seriously the nature of these early works as performances, through which multiple questions can be raised and multiple options explored, both in words and through their dramatic framework. (...) The theological consequences are considerable. A very human Augustine emerges, talking and playing with friends and family, including his mother - and a very sympathetic set of ideas is the result. (shrink)

There at least three ways of thinking about rationality: instrumental, substantive, and intentional. By far, the instrumental account is most influential. This essay proposes that intentional rationality can provide substantive accounts with room to breathe, and in a way that is facially distinct from instrumental accounts. I suggest that the intentionality of a judgment is made up of what it is about and the orientation through which it is judged, while irrationality is the subversion of a strict supporting connection between (...) the judgment and its corresponding set of coordinated attitudes (reasons). It follows that irrational intentionality is made up of episodic states where a judgment is subverted because of a misalignment between what it is about and the way the judge is oriented towards its contents. Four examples of irrational intentionality are considered: passivity towards ends, constitutive ignorance towards facts, delirious paranoia towards objects, and a disjunctive orientation towards categorizations.

When it comes to disagreements about religious, moral or political questions, many people consider a tolerant ‘live-and-let-live’ attitude to be the best reaction toward conflicting opinions. However, many epistemologists are rather skeptical about the epistemic acceptability of such a tolerant attitude. More specifically, the worry is that a tolerant reaction toward recognized disagreement is necessarily epistemically irrational. After setting out this worry in a little more detail, I will present and discuss three different arguments for the epistemic irrationality of (...) a tolerant attitude toward disagreement. I will argue that while all these arguments ultimately fail, they still reveal some substantial limitations to the epistemic adequacy of intellectual tolerance. (shrink)

The standard representation theorem for expected utility theory tells us that if a subject’s preferences conform to certain axioms, then she can be represented as maximising her expected utility given a particular set of credences and utilities—and, moreover, that having those credences and utilities is the only way that she could be maximising her expected utility. However, the kinds of agents these theorems seem apt to tell us anything about are highly idealised, being always probabilistically coherent with infinitely precise degrees (...) of belief and full knowledge of all a priori truths. Ordinary subjects do not look very rational when compared to the kinds of agents usually talked about in decision theory. In this paper, I will develop an expected utility representation theorem aimed at the representation of those who are neither probabilistically coherent, logically omniscient, nor expected utility maximisers across the board—that is, agents who are frequently irrational. The agents in question may be deductively fallible, have incoherent credences, limited representational capacities, and fail to maximise expected utility for all but a limited class of gambles.

When the Parrondo effect was discovered a few years ago (Harmer and Abbott 1999a, 1999b), it was hailed as a possible mechanism whereby, in a kind of collaboration of failure, losing strategies could be combined to yield profit. The precise relevance of the Parrondo effect to natural and social phenomena is however still unclear. In this paper we give specific examples, first in the artificial setting of a gambling machine, and then in more natural applications to genetics and to environmental (...) policies. This last example touches questions of rational behaviour and expected utility in a novel setting. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Setting the Stage for a Dialogue:Aesthetics in Drama and Theatre EducationAlistair Martin-Smith (bio)For us, education signifies an initiation into new ways of seeing, hearing, feeling, moving. It signifies the nurture of a special kind of reflectiveness and expressiveness, a reaching out for meanings, a learning to learn.—Maxine Greene, Variations on a Blue Guitar1Examining the aesthetics of the complementary fields of educational drama and theatre is like looking through a (...) kaleidoscope. If you turn it one way, you see one colorful pattern; if you turn it the other way, you see yet another. The multiplicity of approaches to drama and theatre education, each with its own aesthetic pattern, often obscures the common ground they all share. As a result, in its unique emphasis on art, pedagogy, and society, each may have its own aesthetic pattern; yet only by looking closely at each distinct pattern can we understand more of the power of drama and theatre to develop human consciousness.In Western education, aesthetic learning seems incidental to the assessment of learning. How did this happen? For Descartes, whose Cartesian philosophy dissociated mind from body, aesthetic feelings are irrational, since they originate in the body's senses rather than in the mind. Theories of education focused on the primacy of cognition, denying feelings in the erroneous belief that learning is independent of its context. Conversely, aesthetic education is concerned with the quality of experience, how it is felt. Dewey believed that "learning by doing" was a "consummatory" experience for the learner; it was dramatic, dialogic, and felt. The confusion between subjective and objective aspects of the aesthetic experience makes aesthetic evaluation difficult, and this may be why cognitively dominated education has steered clear of aesthetics. Richard Courtney recognized that there is an important distinction to be made between aesthetic symbols and [End Page 3] artistic symbols: "Aesthetic symbols emphasize feeling; artistic symbols are context-dependent—they only have meaning in the context of art."2David Best argues that "the failure to recognise the distinction between the aesthetic and the artistic contributes largely to the trivialisation of the potential of the arts in education."3 He points out that "... it may often be necessary to take into account, at least implicitly, wider factors... in order to judge whether [an] appraisal was aesthetic or artistic."4 What are these wider factors, and how can audiences attend to them? As Christopher Havell reminds us,There is increasing pressure on drama teachers to use their teaching expertise purely for the development of social and life-skills training. This instrumental work may, at times, closely resemble the drama process, but the intentions will be confined to an experience that simulates or resembles those "real-life situations" that it is expected students will encounter. The aesthetic search for the "universal" at the centre of the particular will not be a relevant aim in any vocational training! One can only hope that the emerging interest in the aesthetic nature of drama and its place in a coherent arts education will encourage teachers and students to reflect on the final inadequacy of any instrumental view.5I believe that it is through the power of aesthetic education that audiences for drama and theatre will come to appreciate the artistic.In Caravaggio's painting David with the Head of Goliath (1606-10), the viewer is confronted with three time periods simultaneously. In his depiction of David, Caravaggio paints the shepherd-king of the Old Testament who prefigures Christ, but he is also modeled on Caravaggio's lover. David holds the severed head of Goliath down low in such a way as to engage the private viewer rather than to evoke the public spectacle.6 As I understood that the head of Goliath was actually a self-portrait of the painter not long before his death, I experienced a moment of instantaneity that shocked me into a new awareness of my own mortality, my relation to life and death. As it is Caravaggio's last journey, so is it our own. While Caravaggio's penultimate painting is recognized in terms of its artistic achievement, the moment of self-recognition on the part of the...

I discuss the comments from Professor Piotr Lichacz on my book, Setting Health-Care Priorities. What Ethical Theories Tell Us. The idea that our reluctance to let go of life and abstain from marginal life extension is irrational is defended against his criticism. The methodology used in the book—urging us to rely in our testing on ethical theories on the content of our considered moral intuitions—is explained at length and the notion of cognitive psychotherapy involved in it is defended.

To better understand the purchasing decision-making process of humane pork, and examine the internal relationship between consumers’ preferences in rational consumption and irrational decoy scenarios, 405 consumers in Wuxi City, Jiangsu Province, and China were surveyed. Attributes were set for breeding time, breeding mode, diet cleanliness label, and price, and the first three among them reflect animal welfare conditions. The results show that in the rational consumption scenarios, consumers pay the most attention to the price attribute, followed by the (...) attribute of diet cleanliness label, breeding mode, and breeding time. In the irrational decoy scenarios, consumers are most likely to be affected by the attribute decoy of diet cleanliness label, which have the utility of avoiding food safety risks. In addition, the decoy effect triggered by the price attribute which owned the highest degree of rational preference among consumers is also substantially higher, but lower than that of the diet cleanliness label attribute. The decoy effect caused by the breeding time attribute with the lowest degree of consumers’ rational preference is also the lowest. Therefore, the government should strengthen the publicity of the humane treatment of pigs before slaughter, and improve the certification and management system of pigs’ diet cleanliness. Besides, marketers are suggested to emphasis the product attributes that customer’s value the most in their advertising. (shrink)

The Institute of Medicine and the American Heart Association have issued a “call to action” to expand the performance of cardiopulmonary resuscitation in response to out-of-hospital cardiac arrest. Widespread advertising campaigns have been created to encourage more members of the lay public to undergo training in the technique of closed-chest compression-only CPR, based upon extolling the virtues of rapid initiation of resuscitation, untempered by information about the often distressing outcomes, and hailing the “improved” results when nonprofessional bystanders are involved. We (...) describe this misrepresentation of CPR as a highly effective treatment as the fetishization of this valuable, but often inappropriately used, therapy. We propose that the medical profession has an ethical duty to inform the public through education campaigns about the procedure's limitations in the out-of-hospital setting and the narrow clinical indications for which it has been demonstrated to have a reasonable probability of producing favorable outcomes.

Within the second book of his Rhetoric, intent upon the art of persuasion, Aristotle sets forth theearliest known methodical explication of human emotions. This placement seems rather peculiar,given the importance of emotional dispositions in both Aristotle’s theory of moral virtues and in hismoral psychology. One would expect to find a full account of the emotions in his extensivetreatment of virtues as it appears in his ethical treatises, or as part of his psychological system in DeAnima. In none of these (...) places, however, does a systematic treatment of this part of Aristotle’spsychology emerge as it does in the Rhetoric. Such is a surprising, seemingly unusual phenomenonin consideration of Aristotle’s extreme care for and obsession with organization and categorization.Earnest analysis, however, reveals the intricate ingeniousness of Aristotle’s innovative project.Emotion, based upon the interplay between what Aristotle deems to be the ‘uniquely human’rational and irrational parts of the human soul, involves Being and Being’s cognition of itself, andits dialectical encounter with the faculty of pure reason. Within this encounter is born humanemotion.According to this formula, emotion is a phenomenon that is linked to concrete human existencewhile at the same time being fundamentally involved with cognition. Emotion bridges the gapbetween the this-worldliness of the human and his keen logic as a rational being. Such anunderstanding allows Aristotle to assert that emotional appeal, which often stands at the core ofrhetoric, is not necessarily a way of tricking people or avoiding critical response, but can be used topersuade by bringing facts to people’s awareness. Through his novel rhetoric of emotion, Aristotlenot only sheds light on the human condition, he brings rhetoric itself into the realm of the rationaland the valid as a suitable means of human discourse.

Reason, long held as the highest human achievement, is under siege. According to Aristotle, the capacity for reason sets us apart from other animals, yet today it has ceased to be a universally admired faculty. Rationality and reason have become political, disputed concepts, subject to easy dismissal. Julian Baggini argues eloquently that we must recover our reason and reassess its proper place, neither too highly exalted nor completely maligned. Rationality does not require a sterile, scientistic worldview, it simply involves (...) the application of critical thinking wherever thinking is needed. Addressing such major areas of debate as religion, science, politics, psychology, and economics, the author calls for commitment to the notion of a "community of reason," where disagreements are settled by debate and discussion, not brute force or political power. His insightful book celebrates the power of reason, our best hope--indeed our only hope--for dealing with the intractable quagmires of our time. (shrink)

Effective inseparability of pairs of sets is an important notion in logic and computer science. We study the effective inseparability of sets which appear as index sets of subsets of an effectively given topological T0-space and discuss its consequences. It is shown that for two disjoint subsets X and Y of the space one can effectively find a witness that the index set of X cannot be separated from the index set of Y by a recursively enumerable (...) set, if X intersects the topological closure of an effectively enumerable subset of Y. As a consequence of a more general parametric inseparability result a theorem of Rice-Shapiro type is obtained. Moreover, under some additional requirements it follows that nonopen subsets have productive index sets. This implies a generalized Rice theorem: Connected spaces have only trivial completely recursive subsets. As application some decision problems in computable analysis and domain theory are studied. It follows that the complement of the halting problem can be reduced to the problem to decide of a number whether it is a computable irrational. The same is true for the problems to decide whether two numbers are equal, whether one is not greater than the other, and whether a number is equal to a given number. In the case of an effectively given continuous complete partial order the complexity of the last problem depends on whether the given element is the smallest element, in which case the complement of the halting problem is reducible to it, whether it is a base element and maximal, then the decision problem is recursively isomorphic to the halting problem, or whether it is none of these. In this case, both the halting problem and its complement are reducible to the problem. The same is true in nontrivial cases for the problems whether an element belongs to the basis, whether two elements of the partial order are equal, or whether one approximates the other. In general, for any nonempty proper subset of the partial order either the halting problem or its complement can be reduced to the membership problem of the subset. (shrink)

Public value facilitates the democratization of public policy making, it should be the common-sense and bottom-line for policymakers. However, it has not been paid enough attention by the practical and theoretical circles. How to realize the transformation from individual value to public value and make public policies be in line with citizens’ preferences, is vital for the democratic politics. How individual value becomes public value in the agenda-setting stage during the policy-making process? What are the key influencing factors? Using the (...) case of Yangzhou Chemical Co. Youjia Program and interview data, this paper studies the mechanisms that could make individual value be transformed to public value through deeply observing and measuring individuals’ attitudes, demands, motivations, beliefs, and preferences. We argue that (1) public value is an essential foundation for agenda setting and guidance to policy making, whereas individual value cannot naturally substitute value orientation in the public sphere. (2) Transferring individual value to public value can reduce divergence appearing in the subsequent stage in policy activities. (3) Factors that can influence this transformation are policy subjects, relations, rule and expression channels with various determinants and conditions. (4) Public value can terminate irrational and unreasonable policies or drag the policy issues back into the agenda-setting stage. This paper provides unique insights into why individual citizens enter the public sphere to take public actions so that the Chinese government can recognize additional public opinions, which makes cooperative governance be realized.

In this paper we describe in some detail a formal computer model of inferential discourse based on a belief system. The key issue is that a logical model in a computer, based on rational sets, can usefully model a human situation based on irrational sets. The background of this work is explained elsewhere, as is the issue of rational and irrational sets (Billinge and Addis, in: Magnani and Dossena (eds.), Computing, philosophy and cognition, 2004; Stepney (...) et al., Journey: Non-classical philosophy—socially sensitive computing in journeys non-classical computation: A grand challenge for computing research, 2004). The model is based on the Belief System (Addis and Gooding, Proceedings of the AISB’99 Symposium on Scientific Creativity, 1999) and it provides a mechanism for choosing queries based on a range of belief. We explain how it provides a way to update the belief based on query results, thus modelling others’ experience by inference. We also demonstrate that for the same internal experience, different models can be built for different actors. (shrink)

Study, with text of the Yogasūtra of Patañjali, text on Yoga philosophy.

One of the deepest and longest-lasting debates in ethics concerns a version of the Euthyphro question: are choiceworthy things choiceworthy because agents have certain attitudes toward them or are they choiceworthy independent of any agents’ attitudes? Reasons internalists, such as Bernard Williams, Michael Smith, Mark Schroeder, Sharon Street, Kate Manne, Julia Markovits, and David Sobel answer in the first way. They think that all of an agent’s normative reasons for action are grounded in facts about that agent’s pro-attitudes (e.g., her (...) desires, valuing states, normative judgments). According to the most popular brand of internalism, idealizing internalism, an agent’s reasons are grounded, not in her actual pro-attitudes, but rather in what her pro-attitudes would be in suitably idealized conditions. Idealizing internalists presuppose that, for any agent with an irrational set of attitudes, there is one uniquely rational set that that agent would have if she were to undergo the relevant idealizing process. I argue that this assumption is false and that it raises two puzzles for idealizing internalism: one about the existence of practical reasons and another about their normative weight. I argue that idealizing internalists have an adequate solution to the first puzzle but not the second. Indeed, when they try to solve the second puzzle, they confront a dilemma. This second puzzle and the associated dilemma thus constitutes a powerful, but so far unnoticed, difficulty for idealizing internalism. (shrink)

Creationism is usually regarded as an irrational set of beliefs. In this paper I propose that the best way to understand why individual learners settle on any mature set of beliefs is to see that as the developmental outcome of a series of “fast and frugal” boundedly rational inferences rather than as a rejection of reason. This applies to those whose views are opposed to science in general. A bounded rationality model of belief choices both serves to explain the (...) fact that folk traditions tend to converge on “anti-modernity”, and to act as a default hypothesis, deviations from which we can use to identify other, arational, influences such as social psychological, economic and individual dispositions. I propose some educational and public policy strategies that might decrease the proportion of learners who find creationism and anti-science in general a rational choice. (shrink)

We study in a constructive manner some problems of topology related to the set Irr of irrational reals. The constructive approach requires a strong notion of an irrational number; constructively, a real number is irrational if it is clearly different from any rational number. We show that the set Irr is one-to-one with the set Dfc of infinite developments in continued fraction . We define two extensions of Irr, one, called Dfc1, is the set of dfc of (...) rationals and irrationals preserving for each rational one dfc, the other, called Dfc2, is the set of dfc of rationals and irrationals preserving for each rational its two dfc. We introduce six natural distances over Irr wich we denote by dfc0, dfc1, dfc2, d, dmir and dcut. We show that only the four distances dfco, dfc1, d and dmir among the six make Irr a complete metric space. The last distances define in Irr the same topology in a constructive sens. We study further the set Dfc1 in which we show that the irrationals constitute a closed subset. Finally, we make a particular study of the completion Dfc2 of Dfc for the two equivalent metrics dfc2 and dcut. (shrink)

The normativity of so-called “coherence” or “structural” requirements of rationality has been hotly debated in recent years. However, relatively little has been said about the nature of structural rationality, or what makes a set of attitudes structurally irrational, if structural rationality is not ultimately a matter of responding correctly to reasons. This paper develops a novel account of incoherence (or structural irrationality), critically examining Alex Worsnip’s recent account. It first argues that Worsnip’s account both over-generates and under-generates incoherent patterns (...) of attitudes, and then proposes an alternative that both avoids these problems and captures a crucial insight behind Worsnip’s account. According to this account, a set of attitudes is incoherent just in case having all of the attitudes in that set is incompatible with reacting to a question in a way that one is, in virtue of having the attitudes, committed to.

Is unethical conduct necessarily irrational? Answering this question requires giving an account of practical reason, of practical good, and of the source or point of wrongdoing. By the time most contemporary philosophers have done the first two, they have lost sight of the third, chalking up bad action to rashness, weakness of will, or ignorance. In this book, Candace Vogler does all three, taking as her guides scholars who contemplated why some people perform evil deeds. In doing so, she (...) sets out to at once engage and redirect contemporary debates about ethics, practical reason, and normativity. -/- Staged as a limited defense of a standard view of practical reason (an ancestor of contemporary instrumentalist views), Vogler's essay develops Aquinas's remark about three ways an action might be desirable into an exhaustive system for categorizing reasons for acting. Drawing on Elizabeth Anscombe's pioneering work on intention, Vogler argues that one sort (means/end or calculative reasons for acting) sets the terms for all sound work on practical rationality. -/- She takes up Aquinas's work on evil throughout, arguing that he provides us with a systematic theory of immorality that takes seriously the goods at issue in wrongdoing and the reasons for unethical conduct. Vogler argues that, shorn of its theological context, this theory leaves us with no systematic, uncontroversial way of arguing that wrongdoing is necessarily contrary to reason. (shrink)

According to a traditional Cartesian epistemology of perception, perception does not provide one with direct knowledge of the external world. Instead, your immediate perceptual evidence is limited to facts about your own visual experience, from which conclusions about the external world must be inferred. Cartesianism faces well-known skeptical challenges. But this chapter argues that any anti-Cartesian view strong enough to avoid these challenges must license a way of updating one’s beliefs in response to anticipated experiences that seems diachronically irrational. (...) To avoid this result, the anti-Cartesian must either license an unacceptable epistemic chauvinism, or else claim that merely reflecting on one’s experiences defeats perceptual justification. This leaves us with a puzzle: Although Cartesianism faces problems, avoiding them brings a new set of problems. (shrink)

Richard Pettigrew offers an extended investigation into a particular way of justifying the rational principles that govern our credences. The main principles that he justifies are the central tenets of Bayesian epistemology, though many other related principles are discussed along the way. Pettigrew looks to decision theory in order to ground his argument. He treats an agent's credences as if they were a choice she makes between different options, gives an account of the purely epistemic utility enjoyed by different (...) class='Hi'>sets of credences, and then appeals to the principles of decision theory to show that, when epistemic utility is measured in this way, the credences that violate the principles listed above are ruled out as irrational. The account of epistemic utility set out here is the veritist's: the sole fundamental source of epistemic utility for credences is their accuracy. Thus, Pettigrew conducts an investigation in the version of epistemic utility theory known as accuracy-first epistemology. (shrink)

The Web, in particular real‐time interactions in three‐dimensional virtual environments (virtual worlds), comes with a set of unique characteristics that leave our traditional frameworks inapplicable. The present chapter illustrates this by arguing that the notion of “technology relations,” as put forward by Ihde and Verbeek, becomes inapplicable when it comes to the Internet, and this inapplicability shows why these phenomena require new philosophical frameworks. Against this background, and more constructively, the chapter proposes a fundamental distinction between “intravirtual” and “extravirtual” consequences—a (...) distinction that allows us to understand and conceptualize real‐time interactions online more accurately. By relating this distinction to Searle's notion of “condition of satisfaction,” the chapter also shows its implications for judging real‐time, online interactions in virtual worlds as irrational and/or immoral.

The study of rationality and practical reason, or rationality in action, has been central to Western intellectual culture. In this invigorating book, John Searle lays out six claims of what he calls the Classical Model of rationality and shows why they are false. He then presents an alternative theory of the role of rationality in thought and action. A central point of Searle's theory is that only irrational actions are directly caused by beliefs and desires—for example, the actions of (...) a person in the grip of an obsession or addiction. In most cases of rational action, there is a gap between the motivating desire and the actual decision making. The traditional name for this gap is "freedom of the will." According to Searle, all rational activity presupposes free will. For rationality is possible only where one has a choice among various rational as well as irrational options. Unlike many philosophical tracts, Rationality in Action invites the reader to apply the author's ideas to everyday life. Searle shows, for example, that contrary to the traditional philosophical view, weakness of will is very common. He also points out the absurdity of the claim that rational decision making always starts from a consistent set of desires. Rational decision making, he argues, is often about choosing between conflicting reasons for action. In fact, humans are distinguished by their ability to be rationally motivated by desire-independent reasons for action. Extending his theory of rationality to the self, Searle shows how rational deliberation presupposes an irreducible notion of the self. He also reveals the idea of free will to be essentially a thesis of how the brain works. (shrink)

To that extent there obviously can be no responsibility. A mental makeup which renders one (who would (...) not normally be so) substantially incapable of rational conduct constitutes insanity, and in that respect renders the person non-responsible.

Alongside, as I was climbing up the ladder of education, I found myself just as well captivated by the great intellectual stories of our times, in particular 20th century analytic philosophy and, at its core, the machinery of modern logic. How do then the cool contemplative modes of the philosophical and analytic outlooks, that are better fitting of the philosopher's armchair at the fireplace, hang together with the heat of the battlefield or the angst of the ticking clock of time left to the completion of a daring special operation? Growing up I was pondering exactly that. Not accidently, and in fact as consequence, I have chosen a course in life that challenged me to visit the poles of both theory and practice. I set myself on a mission to unravel the tension between the contemplative inquiry, supposedly theoretical, aiming at the logical structure of things, and the uncompromising test of life and action. The puzzle of the gap between theory and practice has become ever since the guiding question of my life. -/- Not long ago, I met two friends, Avner Shor, a veteran combat soldier of the special forces unit I eventually commanded, and Aviram Halevi, a fellow officer with whom I served. Why will we not put into writing the ideas that guided us during our years of military action, we wondered. At that time, I used to deliver the keynote lectures to the senior officers' course of Israel central intelligence organization, the Mossad. For this I already had to put some of these ideas in writing. Avner was quick to introduce me with a notable publisher and even helped me write the first chapter. With Aviram I sat to many meetings, where he would challenge me with key questions, and we followed them with memories of operations and battles, aiming to draw the required lessons. This served me well when I finally sat down to write the first draft of the book. The result was more extensive than me and my friends had expected. I had to add a particularly long chapter dealing with the story of modern philosophy and logic. This was required, I felt, as no decision-making process lives in an intellectual vacuum. Knowingly or subconsciously, the intellectual climate of the time guides us for better or worse with the decisions we finally take. The initial draft was naturally cumbersome and inaccessible. But here I had the privilege of meeting a particularly talented editor, Rami Rothholtz. I found in Rami both an editor and a critical reader. As an infantry combat soldier at youth and now a senior journalist and editor, Rami insisted on simplifying and refining my ideas. Had it not been for his work, this book would have been literally unreadable. *** I opened my book with a brief description of a single night of a special operation deep at the Lebanon Bekaa valley, far away from Israel northern border. The mission was to kidnap a senior terror leader known to be holding in captivity an Israeli pilot. This was also the last special operation I commanded in my military career. A single special operation night, but what had to precede it? For sure, many months of intense and skillful preparations. What is Planning? This is the question with which I open up chapter (2) of the book. I confront in this chapter two approaches to planning. The first is the one I saw as a mission to myself to cultivate in my many years of military service. The second is the one I saw as representing a deep-rooted fallacy that holds a firm grip on today's conventional wisdom about planning. To further examine the logic of the competing models, I was required in chapter (3) to analyze the concept of "The Standard". I argue that the false model of planning has its roots in an attitude of an uncompromising adherence to the power of literal obedience to standards and rules. The standard, or what is outlined by a rule as prescribing a future course of action, is seen as an answer to the fundamental tension between theory (planning) and practice (execution). I argue in contrast that the standard does not produce an answer but rather what I call: "A Well-Defined Question". In essence, it is a meticulously-well-planned invitation to exercise a fresh judgment. A judgement that has as an anchor the default answer that the standard produces but is open to extension as it confronts the new frame of reference of the test of reality. In chapter (4), I present a new tool for planning and execution: "The Polygon of Risks" or "The Polygon of Execution". The Polygon is a geometric illustration of the underlying tension that exists between all dimensions of the operational project. The construction and conceptualization of the trade-offs that exist between the various dimensions - segments of the polygon - is the first topic on the planner's agenda. I position the concepts of "Daring" and "Taking Proactive and Well-Informed Risks" as necessary logical constituents of the polygon and show how in contrast the false model of planning is responsible for an operational culture that is risk-averse. It encourages, in fact, the piling up of false securities at the segments' level that eventually lead to the collapse of the polygon. The necessary trade-offs relationships that exist between the segments of the polygon express the fundamental tension between partnership and competition: partnership in a joint goal and competition over resources, both material and abstract. When this tension is not managed well, that is, when the players' local optimizations overshadow the global optimization required for the success of the project, the execution polygon collapses. In this scenario, we may find the setting of the bar of "High Standards" in a players' spheres of responsibility to conceal a hidden agenda of personal insurances taken against a possible failure. Once the overall risk is not mitigated by way of collaborative joint executional dialogue, the process that leads to a collapse of the polygon is literally unstoppable. *** In chapter (5), I discuss "(Fateful) Decisions". I examine the way in which we should translate the polygon into sequential critical decisions on the timeline. The execution polygon is not a rigid scaffolding but a dynamic conceptual illustration of the -/- project. It will need now to be converted into successive decision junctions. We will find the content of a decision and its timing on the timeline to be inseparable. The right decision is the one that is taken at the right time. The moment of decision is in fact the last moment of deliberation, the first moment available for action, i.e. the first possible "Can" is also the latest possible "Must". Deciding too soon is analog to the "Jumping of the Gun". The decision maker is forcing a pre-conceived answer to a state of affairs not ripe for an answer, e.g. the target in the shooting range is not yet erected. Late to decide and the decision maker may envision what he or she should have done but reality is no longer available for them to harness it right, e.g. consider a tennis player's frustration when reviewing a too-late-to-react move in the video replay. I review in this chapter many fateful decisions, both historical, from Napoleon's Waterloo, to a Bridge Too Far of WWII, to the failed rescue attempt of American hostages at the time of the Iranian Revolution, as well as fateful decisions I had to take in the course of my military life, both in combat and in special operations, and show the sense in which they all answer to our analysis. The theme of chapter (6) is "The Moment of Truth". This is the moment when everything is on the line and from which there is no turning back. I discuss the formative repetitive structure of the schooling and simulation phase and contrast it with the "One Shot, One Opportunity" nature of the moment of truth. This is extremely helpful when we analyze the logical structure of failures as unwarranted repetitions of past lessons. The schooling curriculum indeed consists of important abstractions drawn from lessons of the past. However, it is when we project them in a fashion that is literal or mechanical that we cross path with the possibility of a failure. The paradox of education is that what we must repeat in school and simulation must be extended and not repeated in real life. What is required of us so we do not fall into the fallacy of repetition in face of the moment of truth is the core subject of the discussion of this chapter. In chapter (7), I took a lengthy philosophical detour surveying the intellectual drama of modern logic, and in general, the story of 20th century analytic philosophy. Readers who choose to bypass the somehow demanding narrative of this drama can do so and still keep the argumentative thread of the book. However, even by way of skipping the more technical parts, I would still urge the readers to delve into the discussion in this chapter as I believe this would grant them a deeper understanding of the overall conceptual framework. I explore here the work of two key figures: the logician Kurt Gödel and the philosopher Ludwig Wittgenstein, both were crowned in 2000 by TIME Magazine, as the leading Logician and Philosopher, respectively, of the 20th Century. I review the fascinating logical result of Gödel's Incompleteness Theorem and examine its relevance as setting a theoretical limit to the power of formalization. This amazing logical result - a result that shakes the logical foundations of 20th century thought in as much as the discovery of irrational numbers shook the foundations of the Pythagorean program of the ancient Greeks - bears significantly on the question of action and the blind trust we place in the power of formalization in the form of protocols and rules. It is here that Wittgenstein's philosophy enters in full force. We follow Wittgenstein as he dismantles our conception of rules as if there were "Railroads to Infinite", i.e. as prescribing for us in-advance their proper employments in all possible -/- future eventualities. Instead we propose that the dilemma of action demands of us an extension of rules rather than a mechanical or blind repetition of their literal imperative. In turn, this extension can serve as a new lesson added to the curriculum of school and simulation. The theme of chapter (8), the concluding chapter, is Strategy, Logic, and Ethics. The chapter comes to place the ethical dilemma in the conceptual map we presented in the book. I discuss here the tension between strategy as a process of setting goals and deriving backward as it were the steps that are necessary for achieving these goals, to the inescapable dictation of the ethical imperative. This unavoidable tension is particularly important against the backdrop of contemporary culture that is guided by a vision of personal success and achievement that may threaten our ability to do what is right. Most of all, I am troubled in this chapter, with the role logic may play, first as a liberating force enabling a change that is tuned to the ethical imperative, and second, as a force designed to justify on logical grounds, as it were, the existing power structure. It is in this junction that brave individuals will be called to challenge the governing logic of the zeitgeist - logic that operates now as an oppressive force that serves the vested interest of beneficials of the existing order. When success is favored over doing what is right, as we must admit is the prevailing cultural mood of our times, that the words of Emanuel Kant carry their full weight: "Do the Right thing and leave the Consequences to God". For this we need heroes and heroines that challenge the time by bearing the full weight of responsibility that comes with the doing of what is Right. *** This book was written more than anything from the perspective of the heroes and heroines of action. Sometimes they may be missing the exact words or the full insight into the solid logical complexity that stands between them and the doing of what is right. They feel what is right to do on the battlefield of life, whether in real battle, in political or economic life or whether in the life of creativity and the quest of the intellect. They do need, in analogy, proper logical and intellectual artillery. I hope they will find the logical cannons they require as they travel through the pages of this book. The rest is in their hands at the Moment of Truth. -/- Doron Avital, Tel Aviv 2011 -/- . (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Jean-Jacques Rousseau: A Friend of VirtueMatthew SimpsonJoseph R. Reisert. Jean-Jacques Rousseau: A Friend of Virtue. Ithaca, NY: Cornell University Press, 2003. Pp. xiv + 211. Cloth, $42.50.This important book is an interpretation and defense of Rousseau's theory of moral education, in which the author explains and justifies Rousseau's ideas about what virtue is, why it is important, and how it can be cultivated.Briefly, this is his reading: in (...) advanced societies, people come to possess intense and incoherent passions, enflamed by amour-propre, which set them at odds with themselves and with each other, making bourgeois existence unsatisfying and exploitive. To create a better life, people must learn to restrain their desires in a way that promotes their own happiness; they must be taught virtue, which Reisert defines as, "the strength of character to rule over one's passions, so that one can make oneself do what one knows one ought to do" (8). Finally, the best model for the moral educator is not ruler to ruled, but friend to friend.The book is both a defense of this interpretation of Rousseau, and a defense of Rousseau's social and psychological theory itself, most notably against Aristotle, Locke, and Buffon. While the two lines of argument do not go together seamlessly, Reisert offers a number of contributions to Rousseau scholarship and to social thought, especially as it intersects with liberal political theory. He divides the work into two parts. The first explains Rousseau's theory of human nature and his diagnosis of the ills of society. The second interprets and defends his ideas about how to remedy that condition through the cultivation of virtue by means of friendship. The final chapter discusses the importance of virtue for contemporary liberal politics.The first half of the book, on Rousseau's "physics of the soul," touches on self-love, pity, vanity, and conscience. For some reason, Reisert limits his discussion largely to the meaning of amour-propre in the second Discourse and Emile to the exclusion of other issues and other books. Even so, he gives an interesting interpretation of amour-propre, and how it leads to the restless, banal misery that both authors think is characteristic of modern life.The problems of this section come when Reisert attempts to defend Rousseau. He argues that his theory of human nature is to be preferred because it answers questions that others cannot, such as how essentially asocial beings have come to live in societies. Yet, this question and some others he discusses come into being only because of Rousseau's own assumptions, for example that people are asocial in the first place. So, Rousseau's ability to solve puzzles that exist only on the basis of his own principles cannot be taken as evidence for those principles without begging the question.The second half of the work is more innovative. Reisert makes two basic arguments: that only virtue can alleviate the dissatisfactions of bourgeois existence; and that only the relationship of friendship can bring about this "education to virtue" (141). The first is less controversial given that he defines virtue simply as the power to restrain irrational desires for the sake of happiness; yet he goes on to make an interesting distinction between the virtue of Socrates who does not have irrational desires to begin with, and that of Emile who has them but can control them.The most original part of the book is his argument that only the relationship of friendship can foster virtue. He says that the amour-propre which makes people miserable also makes them resistant to efforts to improve their character. "A friend," on the other hand, "can, through force of personality and the power of example, exert a potent influence on his friend without thereby provoking resistance or inspiring resentment" (171). He gives a fascinating account of how a friend can be a kind of better self through whose eyes one sees the source of one's own dissatisfaction and the need for virtue to make life enjoyable. His most path breaking suggestion is that in his writings, especially Emile, Rousseau intended to be such a friend to... (shrink)

In "Disabilities and First-Person Testimony: A Case of Defeat?" Hilary Yancey argues that in at least some cases we have “no significant reason to distrust” the evidential value of first-person testimony concerning the impact of a physical disability on that individual’s well-being. Her argument is premised on a defeasible principle of trust: One should trust the testimony of others regarding p whenever one recognizes that the testifier is in a position to know p. Since the subjective component of wellbeing is (...) fist-person privileged, that is, ordinarily the subject herself is in the best position to know, an audience to such testimony must be aware of a defeater in order to shift the burden of proof and block the testimony from counting as evidence. In the body of the paper Yancey argues that 1) conflicting first-person testimony does not constitute an inescapable content defeater and 2) neither irrational adaptive preferences nor low life expectations inescapably undercuts the reliability of these testifiers regarding matters of their own subjective well-being. The burden of proof is not globally shifted by either kind of defeater, Yancey argues, so at least some first-person testimony about disability must inform our beliefs about the nature of disabilities. In my comment I ask and attempt to answer three questions on Yancy’s behalf, then invite her to set me straight if I have it wrong. I go Kantian along the way. 1. Whence arises the worry, and why focus on these defeaters? 2. How common is PNT, anyway, and why does it matter? 3. On what grounds should we distrust PNT in particular cases? (shrink)

There are at least two threads in our thought and talk about rationality, both practical and theoretical. In one sense, to be rational is to respond correctly to the reasons one has. Call this substantive rationality. In another sense, to be rational is to be coherent, or to have the right structural relations hold between one’s mental states, independently of whether those attitudes are justified. Call this structural rationality. According to the standard view, structural rationality is associated with a distinctive (...) set of requirements that mandate or prohibit certain combinations of attitudes, and it’s in virtue of violating these requirements that incoherent agents are irrational. I think the standard view is mistaken. The goal of this paper is to explain why, and to motivate an alternative account: rather than corresponding to a set of law-like requirements, structural rationality should be seen as corresponding to a distinctive kind of pro tanto rational pressure—i.e. something that comes in degrees, having both magnitude and direction. Something similar is standardly assumed to be true of substantive rationality. On the resulting picture, each dimension of rational evaluation is associated with a distinct kind of rational pressure—substantive rationality with (what I call) justificatory pressure and structural rationality with attitudinal pressure. The former is generated by one’s reasons while the latter is generated by one’s attitudes. Requirements turn out to be at best a footnote in the theory of rationality. (shrink)

Belief in conspiracy theories is typically considered irrational, and as a consequence of this, conspiracy theorists––those who dare believe some conspiracy theory––have been charged with a variety of epistemic or psychological failings. Yet recent philosophical work has challenged the view that belief in conspiracy theories should be considered as typically irrational. By performing an intra-group analysis of those people we call “conspiracy theorists”, we find that the problematic traits commonly ascribed to the general group of conspiracy theorists turn (...) out to be merely a set of stereotypical behaviours and thought patterns associated with a purported subset of that group. If we understand that the supposed prob- lem of belief in conspiracy theories is centred on the beliefs of this purported sub- set––the conspiracists––then we can reconcile the recent philosophical contribu- tions to the wider academic debate on the rationality of belief in conspiracy theories.

Summary To judge a belief, emotion, or action irrational is to make a normative judgment. Can such judgments be objective? It is argued that in an important class of cases they can be. The cases are those in which a person has a set of attitudes which are inconsistent by his or her own standards, and those standards are constitutive of the attitudes. Constitutive standards are standards with which an agents' attitudes and intentional actions must generally accord if judgments (...) of irrationality are to be intelligible.RésuméJuger irrationnelles une croyance, une émotion ou une action, c'est faire un jugement normatif. De tels jugements peuvent‐ils ětre objectifs? On montre qu'ils peuvent l'ětre dans une classe importante de cas: ceux où une personne a un ensemble d'attitudes qui sont inconsistantes avec ses propres normes, ces normes étant constitutives des attitudes considérées. Les normes constitutives sont des normes avec lesquelles les attitudes et les actions intentionnelles des agents doivent s'accorder pour que les jugements d'irrationalité deviennent intelligibles.ZusammenfassungWenn wir einen Glauben, eine Emotion oder eine Handlung als irrational beurteilen, so fällen wir ein normatives Urteil. Kann ein solches objektiv sein? Es wird argumentiert, dass dies für eine wichtige Klasse von Fällen zutrifft. Die Fälle sind diejenigen, in welchen eine Person eine Menge von Haltungen hat, die nach ihren eigenen Massstäben unvereinbar sind, und wo diese Massstäbe für die Haltungen konstitutiv sind. Konstitutive Massstäbe sind solche, mit denen die Haltungen und absichtlichen Handlungen des Handelnden im allgemeinen übereinstimmen müssen, wenn Urteile über Irrationalität verständlich sein sollen.

Several of William James' finest essays are brought together in this collection, including his spiritual masterwork The Will to Believe, and his famous lecture concerning immortality. The Will to Believe was first delivered as a lengthy lecture by William James in 1896. Following a strong reception, it was later published as a distinct book in its own right. Setting out to defend the right of individuals to be religious irrespective of pure logic and reason, the lecture highlights many of the (...) proven advantages conferred by the belief in a guiding divine force. The benefits of belief to the believer are thus noted. James deftly cites many real life examples to prove his points - noting that many tasks or duties require confidence, he notes how individuals can perform and surmount difficulties if they believe in the divine. For such persons to abandon faith would therefore be irrational, as their religious beliefs have helped them in life. This argument is closely aligned with James' personal philosophical alignment with pragmatism. The Will to Believe also contains arguments in favor of persons having their own free will. James contested simply that as he believed in his own free will, he had it. As well as this, we hear several philosophical arguments in which James discusses the merits of empiricism versus absolutism. Other essays in this compendium include 'Is Life Worth Living?' and 'The Dilemma of Determinism'. In these and other writings, James demonstrates a superb command of philosophical principles and theoretical daring, at various times explaining and refuting established discussions on the subjects. The final essay in this edition, Human Immortality, sees James object to the notion that humans cannot be immortal if their bodies and minds are separated due to death. He objects to the assertion that human thought is concluded if the brain ceases to function, noting that human consciousness exists with the world and may philosophically have a life of its own. Notable for both his psychological and philosophical ideas, William James would author numerous lectures and books surrounding both subjects. The importance of spiritualism to the human being, the permanence of the spirit, and its effects on the thought processes, is but one area in which James distinguished himself. (shrink)

Many of our beliefs behave irrationally: this is hardly news to anyone. Although beliefs’ irrational tendencies need to be taken into account, this paper argues that beliefs necessarily preserve at least a minimal level of rationality. This view offers a plausible picture of what makes belief unique and will help us to set beliefs apart from other cognitive attitudes.
