Expressivists famously have important and difficult problems with semantics and logic. Their difficulties providing an adequate account of the semantics of material conditionals involving moral terms, and explaining why they have the right semantic and logical properties – for example, why they validate modus ponens – have received a great deal of attention. Cian Dorr [2002] points out that their problems do not stop here, but also extend to epistemology. The problem he poses for expressivists is the problem (...) of wishful thinking. David Enoch [2003] has claimed that expressivists can avoid wishful thinking, and offered a fairly detailed account of how. In this paper I explain the details of Enoch’s account, and why his reasoning fails in several different places. (shrink)

Replying to Queen Elizabeth II who in November 2008 asked why so few economists had warned about the emerging financial crisis, a group of eminent economists of the British Academy, claimed that while this failure had many causes, the most important was principally a failure of the collective imagination of many bright people, to understand the risks to the system as a whole. The paper suggests that this failure is due also to the still heavy influence of the paradigm of (...) rational expectations, that did not provide the intellectual tools to grasp the signs of the impending financial crisis. The paper explores the development of Muth’s rational expectations hypothesis and the parallel development of Simon’s idea of bounded rationality—two opposite views about economic behavior that originated in the same context, during the early 1960s at Carnegie Mellon. It is shown that the latter, while marginalized for decades from the core economic ideas, generated a wide development in cognitive psychology, problem solving and experimental economics that grew up in the last decades and now permit a more profound analysis of human behavior in economic and organizational contexts, that can be the seed of a new thinking in economics. The challenge for economists is to use this new toolbox to incorporate in their models real human behaviors, getting out from the economy of wishful thinking. (shrink)

Cian Dorr has argued that non-cognitivists must think of reasoning from moral premises to empirical conclusions as akin to wishful thinking. Defenders of non-cognitivism have responded that an adequate solution to the Frege-Geach problem would explain relations of entailment and implication between moral and nonmoral claims and thereby also handle Dorr’s objection. This paper offers a new, more specific, interpretation of Dorr’s objection and one that makes it distinct from worries about Frege-Geach. The paper also explains why (...) non-cognitivists might still reasonably be optimistic that they can allay this version of the worry. Still, successfully undercutting the worry also undercuts one of the prime reasons offered on behalf of non-cognitivism—arguments based on the Humean Theory of Motivation purporting to show that moral judgments cannot be beliefs.

During 2007/2008 Nicholas Rescher continued his longstanding practice of writing occasional studies on philosophical topics, both for formal presentation and for informal discussion with colleagues. While his forays of this kind have usually been issued in journal publications, this has not been so in the present case so that the studies offered here encompass substantially new material. Notwithstanding their thematic variation, these exemplify a problem-oriented method in the treatment of philosophical issues that is characteristic of Rescher's philosophical modus operandi (...) and inherent in its endeavors to treat classical issues from novel points of view. For Rescher usually more concerned with what should be said about a philosophical question than with what X, Y, and Z have said about it, and he inclined to address issues of the latter sort primarily as a means for addressing the former."--BOOK JACKET.

While the science and values literature has seen recurrent concerns about wishful thinking, there have been few efforts to characterize this phenomenon. Based on a review of varieties of wishful thinking involved in climate skepticism, we argue that instances of wishful thinking can be fruitfully characterized in terms of the mechanisms that generate them and the problems associated with them. We highlight the array of mechanisms associated with wishful thinking, as well as (...) the fact that it can be evaluated both from epistemic and ethical perspectives. We argue that it is doubtful that a single unified definition of wishful thinking can be developed. Moreover, the concept of wishful thinking can problematically focus excessive attention on individual and epistemic problems in science, to the exclusion of social and ethical problems. (shrink)

Some contemporary philosophers have argued that expressivism or non-cognitivism, if suitably developed, can solve the well-known Frege–Geach problem. Of course, whether this is true is a matter of debate. Recently, Cian Dorr has advanced an argument that, if successful, would show that this debate is unimportant. For, according to Dorr, a solution to the Frege–Geach problem will not save expressivism from a new and distinct problem, namely that an expressivist theory—even assuming a solution to the Frege–Geach (...) class='Hi'>problem—entails that intuitively rational beliefs are in fact irrational. If Dorr is correct about this, then the new problem he raises would be as devastating as the old Frege–Geach problem is often thought to be. I will argue that Dorr is not correct. Rather than constituting a new and potent objection, the issue Dorr raises—at least absent further argument—does not pose a threat to any expressivist theory which is able to solve the Frege–Geach problem and is otherwise acceptable.

Even if non-cognitivists about some subject-matter can meet Geach’s challenge to explain how there can be valid implications involving sentences which express non-cognitive attitudes, they face a further problem. I argue that a non-cognitivist cannot explain how, given a valid argument whose conclusion expresses a belief and at least one of whose premises expresses a non-cognitive attitude, it could be reasonable to infer the conclusion from the premises.

Irrationality remains a central issue in the philosophy of psychoanalysis. While some approaches in the philosophy of mind have argued that irrationality demands no special account, one of the central conceptual planks of psychoanalytic theory is the notion that irrational motivations have their origin in the dynamic unconscious. This article reviews recent attempts to account for the phenomenon of motivated irrationality, and argues that the problem of self-understanding will remain central to the philosophy of mind so long as we (...) accept the notion of rational agency. Any account of the mind which ignores or denies the appeal of first-person mental phenomena risks rendering itself unintelligible as a convincing account of the conscious subject. (shrink)

In the Qurʾān, it is mentioned that those who disbelieve insist on not believing by putting forward various excuses. One of them is that deniers attribute polytheism to Allah’s wish. When those who disbelieve are asked why they do not believe, they argue that they cannot deny unless Allah wills. On the other hand, expressions in line with the words spoken by the polytheists in the Qurʾān are also attributed to Allah. Such a paradoxical appearance between the verses requires a (...) detailed examination of the subject. In this study, the reasons for using these expressions by the deniers and the historical contexts of the verses will be examined. In addition, we will talk about the discussion of whether the expressions that bind polytheism to the wish of God are absolutely correct, since the subject is related to the wish. Because the interpretation of the verses varies according to both views. In addition to this, whether the deniers are sincere in these words is an element that affects the interpretation. Ahl al-Sunna scholars argue that this proposition is absolutely correct and that the deniers say this sentence with a mocking attitude. On the other hand, Muʿtazilī scholars are of the opinion that the proposition is absolutely wrong and that the deniers say this word with conviction. In addition, while Muʿtazilī scholars think that the nature of the Allah’s wish in both verses is different; Ahl Sunna scholars think that both are the same. Although it seems at first glance that the disbelievers attribute their denial to the legacy of Allah is an attitude that mocks them and believes that Allah is pleased with them, in reality, this is because they deny fate and turn to coercion and do not believe in prophethood and the Hereafter. Because, saying “If Allah willed, we would not associate” is based on the conviction that Allah gave consent to this belief they inherited from their ancestors and left them in accordance with their current beliefs. Devotion to ancestors is not necessarily a bad thing. However, if loyalty to ancestors is through prophethood, it leads to a true faith and ensures that faith is transferred to the next generations in a healthy way. On the other hand, if traditional practices in the name of religion turn into a practice that is against the spirit of the religion after a while, devotion to ancestors becomes an element that leads to denial. The fact that their ancestors lived a very prosperous life in the world even though they also had this belief reveals that they did not believe in the hereafter. Because, according to their opinion, if their ancestors had not been on the right path, God should have punished them in this world. Another reason why they attribute their denial to the legacy of Allah is their lack of belief in prophethood. Because, according to them, prophethood does not have an effect, nor it is necessary, for their faith, which depends only on the legacy of Allah. The most important factor that determines whether the propositions in the verses we examined are correct is the context of the sentence and the intention of the people using the proposition. In other words, the meaning and value of attributing denial to Allah’s wish differs according to the addressee. Because one can mean the falsehood with a true word. The same expression used in different contexts used for this may also be false, due to the difference in context and purpose. As pointed out in verse 148 of Surat al-An’am, a person who has the ability and power to believe, abandon polytheism and rebellion, ignoring this opportunity and power given by Allah and implying that he is pleased with a deed that Allah is not pleased with like idolatry. “If Allah willed, we would not associate idolatry” is a false sentence and false claim that is expressed in the verse. On the other hand, as pointed out in verse 107 of the Surat al-An’am and verse 99 of Surat Yunus, our Prophet who is desperate in the current situation and who has an extreme sense of responsibility because they do not believe, consoled our Prophet that his only duty was to convey the truth to the deniers with the statement “If Allah so willed, they would not have converted to Islam” and “If Allah willed, all those on earth would have believed,” indicating that he allowed them to practice idolatry as a requirement of the test and that he did not force people to believe, in order to state that he is not a guardian and that he should not force them to believe. Therefore, each different situation points to a different dimension of the truth about God’s legitimacy. (shrink)

The rapid development of computers and technology affects modern daily life. Individuals in the digital age need to develop computational thinking skills. Existing studies have shown that programming teaching is conducive to cultivating students’ CT, and various learning models have different effects on the cultivation of CT. This study proposed a problem-oriented learning model that is closely related to programming and computational thinking. In all, 60 eighth-grade students from a middle school in China were divided into an (...) experimental group which adopted the POL model, and a control group which adopted the lecture-and-practice learning model. The results showed that the students who were instructed using the POL model performed better than those who were instructed using the LAP model on CT concepts, CT practices, and CT perspectives. Significant differences were found for CT concepts and CT perspectives, but not for CT practices. Findings have implications for teachers who wish to apply new learning models to facilitate students’ CT skills, and the study provides a reference case for CT training and Python programming teaching.

The study aimed to identify Design Thinking and its use in NGOs in Gaza Strip. In order to achieve the objectives of the study and to test its hypotheses, the analytical descriptive method was used, relying on the questionnaire as a main tool for data collection. The study society was one of the decision makers in the local NGOs in the Gaza Strip. The study population reached 78 local NGOs in Gaza Strip. The overall inventory of the possible study (...) community was based mainly on the use of the SPSS in processing and analyzing the data obtained through the survey tool. Smart-PLS was also used to construct the structural equation model (SEM) Analyzing the relationship between study variables. The study found that Design Thinking mediates the relationship between the management of process design and decision making with a holistic effect. The study showed the interest of local NGOs in creating a good mental image in the local community. And the ownership of local NGOs to the expertise and technical skills required to implement the projects, and showed the adoption of local NGOs in their activities to meet the needs of the beneficiaries and their wishes, and local NGOs analyze the problem, and causes, through data relevant to the decision, based on reference data for decision-making. The main recommendations of the study are: The need for senior management in the local NGOs in Gaza Strip to adopt the methodology of design thinking because of its impact on the sustainability of the projects, design the technical feasibility study and meet the wishes of the beneficiaries.

The author’s goal is to weigh capabilities of theistic reason in regard to the problem of evil, and two formats of reasoning in this regard are strictly differed, i.e. attempts at building theodicies and defenses. The upshot is that while there is no doubt that the great multitude of evils and sufferings in the world are surely beyond reach of any theodicies, it is similarly doubtless that many sound reasons are suitable for countering atheist “evidential refutations”. Some new arguments (...) are offered to counterbalance Rowe’s “friendly atheism”, Draper’s “hypothesis of indifference”, and Schellenberg’s “argument from hiddenness”, along with analysis of wishful thinking underlying all of them.

According to Cian Dorr, non-cognitivism has the implausible implication that arguments like the following are cases of wishful thinking: If lying is wrong, then the souls of liars will be punished in the afterlife; lying is wrong; therefore, the souls of liars will be punished in the afterlife. Dorr further claims that if non-cognitivism implies that the above argument and similar arguments are cases of wishful thinking, then non-cognitivism remains implausible even if one solves the so-called (...) Frege-Geach problem. Dorr’s claims have faced a number of objections, but I believe that Dorr is on to something. So, after summarizing Dorr’s argument and briefly describing three flaws in what Dorr claims, I shall present a distinct objection to non-cognitivism and use the preceding to show what Dorr’s argument gets right and what it gets wrong.

In the movie The Gold Rush Charlie Chaplin and his friend are stranded in a log cabin in the middle of winter while a blizzard rages. The cabin is isolated, and they have a very big problem – there is nothing to eat. They pace around wondering what to do. Charlie's friend starts to see Charlie as a chicken, and he tries to kill him. He chases Charlie around the cabin many times. Eventually they hit upon the idea of (...) boiling an old boot and eating it for dinner. With great delicacy they sit at the table and eat the boot as if it were a gourmet meal. They solved the problem of having nothing to eat. While their solution to the problem did not result in a culinary feast, this example reveals two crucial features of problem solving. First, a problem exists when a goal must be achieved and the solution is not immediately obvious. Second, problem solving often involves attempting different ways to solve the problem. Put more formally, a problem has four components. First, there is an initial state. This is the person's state of knowledge at the start of a problem. Second, there is the goal state: the goal that the person wishes to achieve. Third are the actions or operations that the problem‐solver can use to get to the goal state. Fourth is the task environment that the solver is working in. The task environment consists of the features of the physical environment that can either directly or indirectly constrain or suggest different ways of solving a problem. I will sketch out the main currents of thinking in research in this area, beginning by reviewing the history of research on problem solving and then focusing on a number of important issues in problem‐solving research. Finally, I will give an overview of some recent developments. (shrink)

The argument from inductive risk is considered to be one of the strongest challenges for value-free science. A great part of its appeal lies in the idea that even an ideal epistemic agent—the “perfect scientist” or “scientist qua scientist”—cannot escape inductive risk. In this paper, I scrutinize this ambition by stipulating an idealized Bayesian decision setting. I argue that inductive risk does not show that the “perfect scientist” must, descriptively speaking, make non-epistemic value-judgements, at least not in a way that (...) undermines the value-free ideal. However, the argument is more successful in showing that there are cases where the “perfect scientist” should, normatively speaking, use non-epistemic values. I also show that this is possible without creating problems of illegitimate prescription and wishful thinking. Thus, while inductive risk does not refute value-freedom completely, it still represents a powerful critique of value-free science. (shrink)

Here is a thorough, vividly written introduction to contemporary philosophy and some of the most crucial questions of human existence: the nature of mind and knowledge, the status of moral claims, the existence of God, the role of science, and the mysteries of language, among them. In Thinking It Through, esteemed philosopher Kwame Anthony Appiah shows us what it means to "do" philosophy in our time and why it should matter to anyone who wishes to live a more thoughtful (...) life. Opposing the common misconceptions that being a philosopher means espousing a set of philosophical beliefs, or being a follower of a particular thinker, Appiah argues that "the result of philosophical exploration is not the end of inquiry in a settled opinion, but a mind resting more comfortably among many possibilities, or else the reframing of the question, and a new inquiry." Thinking It Through is organized around eight central topics--mind, knowledge, language, science, morality, politics, law, and metaphysics. It traces how philosophers in the past have considered each subject (how Hobbes, Wittgenstein, and Frege, for example, approached the problem of language) and then explores some of the major questions that still engage philosophers today. More important, Appiah shows us not only what philosophers have thought but how they think, giving us examples we might use in our own attempts to navigate the complex issues that confront any reflective person in the 21st century. Filled with concrete examples of how philosophers work and written in the liveliest prose, Thinking It Through guides readers through the process of philosophical reflection and enlarges our understanding of the central questions of human life.

Dans le Contrat Social , Rousseau semble fonder la légitimité politique sur deux institutions : le Souverain, siège de la puissance législative et le Gouvernement, lieu de la puissance exécutive. Pourtant, dans le livre IV du même ouvrage, il définit la nécessité d'une troisième institution : le Tribunat, situé en tiers entre le Souverain et le Gouvernement. Pour quelle raison Rousseau détermine-t-il la nécessité de ce troisième pouvoir pour fonder la légitimité démocratique ? La raison provient de la dynamique initiée (...) par le Gouvernement qui, tout en étant une institution légitime et nécessaire, tend à s'approprier le pouvoir législatif. Rousseau développe une pensée politique qui prend conscience de la fragilité de la légitimité démocratique, fragilité qui peut se définir par sa tendance à créer, au travers de ses institutions, des volontés indépendantes des citoyens qui défendent des intérêts particuliers en prenant le masque de la volonté générale. Face à ce problème, Rousseau caractérise trois moyens politiques, afin de donner une consistance à la légitimité démocratique : le « Tribunat », « le Droit de Représentation » et enfin la circulation du pouvoir.In the Contrat Social , Rousseau seems to base political legitimacy on two institutions, the sovereign power, seat of legislative power and the government, place of executive power. Nevertheless, in the fourth book of the same work, he defines the necessity of a third political institution, the “Tribunat”, situated entirely between the sovereign power and the government. For what reason does Rousseau determine the necessity of this third power as the base of democratic legitimacy? The reason is the result of the dynamics initiated by the government who, while at the same time being a legitimate and necessary power, tend to take over the legislative power. Rousseau develops a political thinking which realises the fragility of democratic legitimacy, fragility which can be described by its tendency to create, through these institutions, citizen own independent wishes who are defending particular interests in taking the façade of the general will. Facing this problem, Rousseau characterises three political measures in order to give substance to the democratic legitimacy: the “Tribunat”, the “Droit de Représentation”, and finally the circulation of the power.

I question whether, in those cases where physician-assisted suicide is invoked to alleviate unbearable pain and suffering, there can be such a thing as voluntary euthanasia. The problem is that when a patient asks to die under such conditions there is good reason to think that the decision to die is compelled by the pain, and hence not freely chosen. Since the choice to die was not made freely it is inadvisable for physicians to act in accordance with it, (...) for this may be contrary to the patient's genuine wishes. Thus, what were thought to be cases of voluntary euthanasia might actually be instances of involuntary euthanasia. (shrink)

There are at least three basic phenomena that philosophers traditionally classify as paradigm cases of irrationality. In the first two cases, wishful thinking and self-deception, a person wants something to be true and therefore ignores certain relevant facts about the situation, making it appear to herself that it is, in fact, true. The third case, weakness of will, involves a person undertaking a certain action, despite taking herself to have an all-things-considered better reason not to do so. While (...) I think that Stephen Colbert's notion of "truthiness" might be able to fit the mold of each of these three kinds of irrationality, it applies most directly to cases of wishful thinking and self-deception — and it’s these two types of irrationality that I discuss extensively in this paper. As we will see, there are some troubling philosophical problems that arise regarding phenomena like self-deception. But we can use the concept of truthiness to show how these “paradoxes of irrationality” may be resolved without denying the fundamental irrationality of truthiness itself. -/- An earlier version of this paper ("Truthiness, Self-Deception, and Intuitive Knowledge") appeared in "The Daily Show and Philosophy" (2007).

This essay is a response to the proposals of David Klemm and William Klink concerning the construction and testing of theological models. A number of issues are raised for critical attention. The exclusive attention to Christian theology, with no discussion of other religions, poses some significant problems, not the least of which is that cognitive claims of religious thinking are not universal but rather are defined by the particularities of the religious context in which they are made. Although the (...) authors wish to transcend confessionalism, their focus on Christianity and on the concept of God as a basic assumption can be construed as a kind of confessionalism. The argument that theological and scientific models stand in analogy to each other requires more critical examination, particularly with respect to the issues of explanation, prediction, falsification, nesting, and openness. While the argument is persuasive when referred to certain theologians, such as Paul Tillich, it requires some adjustment if it is to apply to other theological systems, such as Process theology.

Finding descriptive titles for books devoted to central issues in philosophy can often become a problem; it is very difficult to be original. Thus the title that I have given to this book is far from novel, having already been used several times by other authors. Nevertheless, I think that I can fairly claim to have employed it in a way that no one else has done before. Concerning my subtitle, some comments are in order. I have added it (...) to emphasize my views regarding the nature and scope of epistemology. In particular, I wish to draw attention to the fact that I conceive its subject matter quite broadly. Rather than equating it, as is often done, with "theory of knowledge," I believe that epistemology should concern itself with the philosophical investigation of human belief in general. The two categories of human belief of most importance to the epistemologist are knowledge and what I shall call in the book "reasonable belief. " In my opinion a complete epistemology must take account of both, attempting to resolve the problems that are peculiar to each. For reasons that I give in the book I believe that knowledge and its problems must be the first concern of the epistemologist. Only after he has developed a satisfactory theory of knowledge can he tum, with any hope of success, to the formu lation of a theory of reasonable belief. (shrink)

Evan Selinger’s review nicely captures the main concerns of my collection of essays, The Politics of Expertise. He raises an important question that is touched on in several essays but not fully developed: the problem of getting expert knowledge possessed by academics into something like public discussion or the public domain. This is of course only a part of the problem of expertise and the larger problem of knowledge in society. But it can be approached in more (...) detail than was done in the book, in terms of the basic ideas of the book, and I will try to do that here. Much of what I will say deals with issues I have addressed in other places, so I will, rather tiresomely, cite myself, for those who wish more elaboration. (shrink)

Open-mindedness appears as a potential intellectual virtue from the beginning of the rise of the literature on intellectual virtues. It often takes up a special role, sometimes thought of as a meta-virtue rather than a first-order virtue: as an ingredient that makes other virtues virtuous. Jason Baehr has attempted to give a unified account of open-mindedness as an intellectual virtue. He argues that the conceptual core of open-mindedness lies in the fact that a person departs, moves beyond, or transcends a (...) certain default cognitive standpoint. Two of his main aims are to show that (1) one does not need to assume a doxastic conflict or disagreement to be at the heart of open-mindedness—that is, there are also instances where the virtue of open-mindedness is needed when there is no opposing view to be considered—and (2) that not all forms of open-mindedness include rational assessment—that is, sometimes being open-minded is not about weighing evidence for and against a claim. So, his main aim is to show that there are various situations that afford open-mindedness, in each of which a slightly different kind of open-mindedness is called for. To unify all these different kinds of open-mindedness is then the goal of his work. He arrives at the following definition of open-mindedness (OM): an open-minded person is characteristically (a) willing and (within limits) able (b) to transcend a default cognitive standpoint (c) in order to take up or take seriously the merits of (d) a distinct cognitive standpoint. In this article, I take seriously Baehr’s suggestion of how to understand open-mindedness as an intellectual virtue and argue that the crux lies in formulating how we can be able to transcend a default cognitive standpoint. This is not as obvious as it has been taken to be in the literature on open-mindedness. Biases, overconfidence, and wishful thinking are difficult exactly because we don’t know that we are engaging in them. That is, they are systematically hidden from our consciousness, otherwise they would not be a bias, overconfidence, or wishful thinking. Hence, the crux of making open-mindedness open-minded is to see how it is possible to make something of one’s own mind visible that is systematically hidden from oneself. I argue that this problem can be solved by looking at research on attention. I base my considerations in this article on Sebastian Watzl’s account of attention, which essentially holds that paying attention is an activity of foregrounding and backgrounding mental contents. That is, attention is the activity of structuring mental contents into a priority structure of foreground and background. If I pay attention to the scene in front of me, I foreground the black letters on my screen, and I background the coffee cup next to them. In this way, I create a priority structure between the letters (as they appear to me) and the coffee cup (as it appears to me). I argue that what allows us to make something of our own mind visible that is systematically hidden from us is a special way of paying attention, hence a special way of foregrounding and backgrounding the involved mental contents. That is, the crux of what enables us to transcend a default cognitive standpoint, the conceptual core of open-mindedness, is a special kind of attention, which I will call ‘open-minded attention’ (OMA). The claim of this article is not that open-minded attention fully describes the virtue of open-mindedness (OMA is not sufficient for open-mindedness). Rather, what I try to show is that in all cases of open-mindedness it turns out that open-minded attention is the necessary component that ensures that we can indeed get rid of prior biases, that is, transcend also those implicit beliefs and expectations that are systematically hidden from us (OMA is necessary for open-mindedness).

This is another contribution to the unending controversy over the two Barbaras. My approach to the problem is hopefully quite new: I wish to view the issue through the prism of modal upgrading. Modal upgrading occurs when a subject term that has only been predicated of assertorically in the premises is predicated of apodictically either: i) in the conclusion of a given syllogism, or; ii) in some proposition that is derived from either the premises of the given syllogism alone (...) or the premises in combination with other propositions that do not refer to the proposition’s subject term. I call the proposition after it has been upgraded the upgraded proposition. When a conclusion is the upgraded proposition, it is obviously a different predicate being predicated than was predicated in the premises. Aristotle endorses this kind of upgrading; it is effectively what happens in any valid mixed modal syllogism when the minor premise is not apodictic (e.g., Barbara LXL). In other cases the upgraded proposition is not a conclusion but still follows from the premises alone. In these cases it is the same predicate being predicated in the upgraded proposition as in the premises, although the quantity of the propositions are different (one is universal, another particular). Aristotle rejects this kind of upgrading and takes its occurrence as sufficient to deny the validity of the given syllogism (e.g., Barbara XLL). I will describe a third type where both the predicate remains the same and the quantity of the proposition remains the same as in the premise, e.g., the upgrading of “All C are B” to “All C are necessarily B”. In these cases it will turn out that the upgraded proposition is not derived from the premises alone, or at least, not syllogistically from the premises alone. This kind of upgrading too is reason for denying the validity of any syllogism from which the upgraded proposition follows as a consequence. I will show that Barbara LXL entails this kind of modal upgrading and should be rejected for this reason. Armed with this notion of modal upgrading I want to attack the problem of the two Barbaras in Aristotle’s apodictic syllogistic. Aristotle himself endorses mixed modal Barbara when the major is necessary and the minor is assertoric, thereby endorsing the first kind of modal upgrading, but rejects Barbara when the minor is necessary and the major is assertoric on the grounds that it leads to the second kind of modal upgrading. Theophrastus endorses the peioram rule which rejects both Barbaras on the grounds that the conclusion can only be as strong as the weakest premise. Łukasiewicz endorses both Barbaras. I will argue that both Barbaras lead to unacceptable modal upgrading and should be taken to be invalid for that reason. Hence, I agree with Theophrastus about the two Barbaras; however, I do not endorse the peioram rule because I think that the negative mixed modal syllogisms generally avoid this problem and is mostly correct.

James Thomas has made yet another valiant attempt to solve the problem in Spinoza of the relation between the infinite attributes of Substance, to which von Tschirnhausen drew attention in Eps. 64 and 65, and to which the answer offered by Spinoza in Ep. 66 seems unsatisfactory. Thomas sets out from an appreciative and fair summary of what I have written on the subject, and then offers an alternative interpretation of Ep. 66 which he says I do not consider. (...) He claims that his interpretation is consistent with my reading of Spinoza as an absolute idealist. I am not sure in what sense he thinks I attribute absolute idealism to Spinoza, but that is a question peripheral to what I wish to discuss here; for whether it is relevant or not, I fear Thomas’s proffered interpretation of Ep. 66 will not serve to resolve Tschirnhausen’s difficulties.

It is astonishing that we humans are able to have, act on and express moral beliefs. This dissertation aims to provide a better philosophical understanding of why and how this is possible especially when we assume metaethical expressivism. Metaethical expressivism is the combination of expressivism and noncognitivism. Expressivism is the view that the meaning of a sentence is explained by the mental state it is conventionally used to express. Noncognitivism is the view that the mental state expressed by a moral (...) sentence is a noncognitive, desire-like state. The central question of this dissertation is this: "How can metaethical expressivists explain that we are able to express moral beliefs?" The shortest answer this dissertation will give is the following: "by becoming `dispositional expressivists´." Dispositional expressivists hold that moral beliefs are dispositions to be in certain mental states that resemble desires. More precisely, a central thesis of this study is that to hold a moral belief is to be disposed to be in a desire-like, noncognitive state where this state has some specific structure. This dissertation arrives at and justifies this thesis by making a number of steps. It starts with preparing the ground by developing a general theory of what it is for a sentence to express a mental state. Roughly, this theory states that for a sentence to express a mental state is for that sentence to be conventionally used to perform a speech act which counts as sincere only if the user or speaker is in that mental state. This theory of expressing satisfies all the constraints that must be satisfied for it to be compatible with the purposes of metaethical expressivism. The next step is to provide a solution to the most notorious semantic problem confronting metaethical expressivism, the problem of explaining how sentences containing moral words can have compositional meaning and stand in logical relations also known as the Frege-Geach or embedding problem. Building on the research of Mark Schroeder, a new expressivist semantics, called `Attitude Semantics´, will be developed for a first-order language. The motivating idea underlying attitude semantics is that expressivists can avoid the problematic feature of so-called `biforcation´ if they treat the structures of the mental states expressed by moral sentences as well as that expressed by non-moral sentences as being isomorphic. In order to give those structures a philosophically interesting interpretation, it will be suggested that we treat sentences as expressing dispositional states. As a toy example we will treat the sentence `murder is wrong´ as expressing the disposition to be for blaming for murder. After dealing with the Frege-Geach problem, I turn to the metaethical expressivists' project of quasi-realism. Two major goals of this project are to explain how moral sentence can be truth-apt and how the states expressed by them can be regarded as moral beliefs. In order to establish those goals I critically examine a number of theories of truth-aptness by providing counterexamples to them. I then present my own theory which says that a sentence is truth-apt iff and because there is a conventional way to use it to express a belief. What is new about this theory is that it treats expressing a belief as being explanatorily more basic than being truth-apt. Belief, according to this theory, explains truth-aptness, not vice versa. This has the important consequence that it shows that what I call the `orthodox strategy´ of quasi-realists is mistaken and needs to be inverted: expressivists must `earn the right´ to moral belief before they can establish that moral sentences are truth-apt, and not the other way round. The second part of this dissertation is then concerned with the question of what it is to hold a moral belief and how they can figure in rational reasoning. In short: it is concerned with earning the right to moral belief. After discussing the major problems confronting a noncognitivist theory of belief, most importantly what I call the `tightrope problem´, I argue for a dispositional form of noncognitivism about moral belief that combines elements from Eric Schwitzgebel's dispositionalism about belief and Sebastian Köhler's `conceptual role expressivism´. This dispositional noncognitivism perfectly matches and justifies the dispositionalist interpretation of the expressivist semantics developed before. In order to fully earn the right to moral belief, however, metaethical expressivists must also deal with several epistemological objections concerning the rationality of moral belief. The first objection I deal with comes from Derek Baker and is directed against Mark Schroeder's specific development of expressivism. I deal with this objection because my own theory bears close resemblance to Schroeder's theory and so it might be worried that it confronts the same issues. Fortunately, we will see that Baker's objection rest on a number of mistaken assumptions and so neither applies to Schroeder's expressivism nor to the version which I defend in this study. The other epistemological objection to metaethical expressivism I deal with is Cian Dorr's famous wishful-thinking objection. In contrast to previous replies to this objection I attack it by directly questioning the central assumption on which it rests, namely that reasoners can never be justified in basing a factual belief on a desire-like state. I argue that this is false, and that under certain conditions reasoning from desire-like mental states to factual beliefs is justified. My argument shows that even if holding a moral belief is being in a desire-like noncognitive state, basing factual belief on a moral belief can give one an epistemic reason for the factual belief. Hence, even if moral thoughts are wishes, moral thinking is not wishful thinking. I take my arguments to earn the dispositional expressivist the right to moral belief. By the previously defended theory of truth-aptness in terms of belief, this allows the dispositional expressivists to conclude that moral sentences are also truth-apt. This finishes the quasi-realist project of this dissertation. In the last part of this dissertation I switch gears and present two unnoted problems for metaethical expressivists having to do with explaining moral motivation. Both arguments are surprisingly simple. The first one is this: if motivation requires a belief as well as a desire (Humeanism), and moral judgments motivate by themselves (internalism), then moral judgments cannot be desires only. If this argument is sound, it shows that the famous `motivation argument´ not only entails the falsity of cognitivism, but also the falsity of noncognitivism. The second argument is the following: moral judgments when combined with suitable external desires motivate to act (externalism), but if motivation requires belief as well as desire (Humeanism), then moral judgments cannot be desires only. I discuss several ways in which noncognitivists might want to deal with those problems, but leave it as an open question whether those solutions will ultimately be viable. Overall, this dissertation makes serious contributions to the research program of metaethical expressivism. It makes proposals for how to solve a number of notorious problems, such as the Frege-Geach problem in semantics and the wishful-thinking problem in epistemology. Besides this, however, it also raises two new problems for metaethical expressivism in the philosophy of action. For those reasons this dissertation will be of interest for anyone who wants to defend or criticize expressivism in metaethics, and more generally, anyone who wants to better understand our astonishing ability to express moral beliefs.

Over the past decade, Jacques Rancière’s writings have increasingly provoked and inspired political theorists who wish to avoid both the abstraction of so-called normative theories and the philosophical platitudes of so-called postmodernism. Rancière offers a new and unique definition of politics, la politique, as that which opposes, thwarts and interrupts what Rancière calls the police order, la police — a term that encapsulates most of what we normally think of as politics (the actions of bureaucracies, parliaments, and courts). Interpreters have (...) been tempted to read Rancière as proffering a formally pure conception of politics, wherein politics is ultimately separate from and in utter opposition to all police orders. Here I provide a different account of Rancière’s thinking of politics: for Rancière politics goes on within police orders and for this reason he strongly rejects the very idea of a pure politics. Politics is precisely that which could never be pure; politics is an act of impurity, a process that resists purification. In carefully delineating the politique—police relation I show that the terms of Rancière’s political writings are multiple and multiplied. Rancière consistently undermines any effort to render politics pure, and therein lies his potential contribution to contemporary political theory. (shrink)

As the title of my paper indicates, I wish to establish a relationship between the problem of an adequate explication of the truth-conception that underlies modern empirical science and the philosophy of C. S. Peirce who is often called the founder of American Pragmatism. In speaking of the truth-conception of modern empirical science, I am thinking of a conception of truth that is necessarily presupposed for an adequate epistemological and methodological understanding of experimental and theoretical natural science and, (...) indeed, for such types of quasi-nomological social science as can be practiced according to the paradigm of natural science. This means that I do not propose directly to thematize the truth-problematics of so called “hermeneutic Geisteswissenschaften” or “critical-reconstructive social sciences” which, in my opinion, transcend the truth-conception as well as the very concept of science.

Many trans women (men) say that they know that they are women (men). Anti-trans activists deny the claims trans people say they know. Many say that social kinds like woman, Latinx, and consent are in some important sense constructed in the social world and are thus open to a certain amount of engineering. I think the claims to knowledge trans people make are correct, and I think it correct that such things as gender, race, and consent are constructed by society (...) and so are prime candidates for what philosophers these days call conceptual engineering. But it is not all that easy to see how the claim about knowledge and the claim that what is known is determined by the vagaries of the social world are to be reconciled. In this paper I argue that this is a real problem, that it has a solution, and that the solution tells us something important about what happens when we contest norms or engineer concepts. (shrink)

In this course we will examine several philosophical puzzles concerning time. We all seem to experience time in a very fundamental and direct way. Yet once we begin to reflect on what time really is, it is easy to feel as puzzled as St Augustine was, who wrote: “If no one asks me, I know what [time] is. If I wish to explain it to him who asks me, I do not know.” The first set of issues we will discuss (...) concern the question whether time is ‘real.’ Time appears to consist of past, present and future. But do the past and the future exist in the same way as the present or is only the present real? Does time ‘flow’? In what ways is time different from space? What would it be to ‘spatialize’ time? Next we will ask whether certain views of time imply that there can be no freedom of the will. One might worry that if facts about the future (including facts about what I will do tomorrow) already existed in the same way as facts about the present exist, then I could not be free to choose what I will do. After all, how can I be free to decide to skip class tomorrow, if it is ‘already’ a fact today that I will attend class? What, if anything, is the connection between various views of time and ‘fatalism’? The third topic we will discuss is time travel. First we will ask whether time travel is a conceptual possibility. As we will see, there are certain conceptual puzzles associated with the possibility of time travel. For example, one might think that if time travel is possible, then I should be able to travel back in time and kill my father before the date of my conception. But this scenario seems to lead to a contradiction. Some have taken considerations such as these to argue that the very idea of time travel is incoherent. Is this right? If not, why not? Then we will look at what the theory of relativity says about the nature of time in general and about the physical possibility of time travel more specifically. Finally we will examine several issues concerning the asymmetry of time.. (shrink)

According to the Transparency Method, one can know whether one believes that P by attending to a question about the world—namely, ‘Is P true?’ On this view, one can know, for instance, whether one believes that Socrates was a Greek philosopher by attending to the question ‘Was Socrates a Greek philosopher?’ While many think that TM can account for the self-knowledge we can have of such a belief—and belief in general—fewer think that TM can be generalised to account for the (...) self-knowledge we can have of other propositional attitudes, such as our desires, intentions, wishes and so on. Call this the Generality Problem. In the present paper, I contrast my own attempt to solve the Generality Problem with several recent ones. I argue that in order to extend TM beyond belief, we must look to the concepts underpinning each kind of mental state. Doing so, I argue, reveals a series of outward-directed questions that can be attended to, in order to know what one desires, intends, wishes and so on. Call this the conceptual approach to extending TM. I support the conceptual approach in the present paper by showing how it generates Moore-Paradoxical sentences that are analogous to the case of belief. (shrink)

This paper is a concise survey of recent expressivist theories of discourse, focusing on the ethical case. For each topic discussed recent trends are summarised and suggestions for further reading provided. Issues covered include: the nature of the moral attitude; ‘hybrid’ views according to which moral judgements express both beliefs and attitudes; the quasi-realist programmes of Simon Blackburn and Allan Gibbard; the problem of creeping minimalism; the nature of the ‘expression’ relation; the Frege-Geach problem; the problem of (...) wishful thinking; the role of moral intuitions; expressivism in aesthetics.

Problem solving in a materially rich environment requires interacting with chance. Sixty-four participants were invited to solve 5-letter anagrams presented as movable tiles in conditions that either allowed the participants to move the tiles as they wished or only allowed random shuffling (without rearranging the tiles post shuffling) thus contrasting pure luck with an interactive model. We hypothesised that shuffling would break unhelpful mental sets and introduce beneficial unplanned problem-solving trajectories. However, participants performed significantly worse when shuffling, which (...) suggests luck plays less of a role than has been previously suggested. Granular analysis of seven critical cases revealed arbitrary path dependency across both conditions and moments of missed luck. It also questions current models of non-agentic luck and the ability to separate agent and luck. This research has implications for fostering better problem solving in an uncertain and fluid world.

Many believe that quantum mechanics makes the world hospitable to the tensed theory of time. Quantum mechanics is said to rescue the significance of the present moment, the mutability of the future and possibly even the whoosh of time’s flow. It allegedly does so in two different ways: by making a preferred foliation of spacetime into space and time scientifically respectable, and by wavefunction collapse injecting temporal ‘becoming’ into the world. The aim of this paper is to show that the (...) reasoning underlying these claims is wishful thinking. Against the first claim I develop what I call the “coordination problem” for tensers. The upshot of this problem is that if tensers escape the threat of relativity, they do so only by embracing conflict with the branch of physics they believed saved them, quantum mechanics. I then step back from the fray and examine some methodological issues, concluding that scientific methodology will always be “against” tenses as they are currently conceived. The Appendix deals with the confused tangle of issues linking wavefunction collapse to an open future. (shrink)

The ways in which we exercise intentional agency are varied. I take the domain of intentional agency to include all that we intentionally do versus what merely happens to us. So the scope of our intentional agency is not limited to intentional action. One can also exercise some intentional agency in omitting to act and, importantly, in producing the intentional outcome of an intentional action. So, for instance, when an agent is dieting, there is an exercise of agency both with (...) respect to the agent’s actions and omissions that constitute her dieting behavior and in achieving the intended outcome of losing weight. In our mental lives we exercise intentional agency both in performing mental actions and when we intentionally produce certain outcomes at which our mental actions are aimed. The nature and scope of our intentional agency in our mental lives with respect to controlling the acquisition of mental states such as belief, desire, and intention is a topic that is of interest in its own right. In this essay, I will focus solely on our control over coming to believe. Understanding what sort of control we have our beliefs has far-reaching implications. For instance, theorizing about self-deception and wishful thinking is aided by theorizing about what if any intentional agency we can exercise with respect to acquiring beliefs. Another often mentioned concern that motivates thinking about doxastic agency comes from religion (when conversion requires a change of belief). We also hold persons morally and epistemically responsible for beliefs they have or fail to have. Finally, some deontological theories of epistemic justification require that agents be able to exercise a robust form of doxastic control. Fruitful work on any of these problems requires that we have an account of our intentional agency in acquiring beliefs. There are at least three loci of doxastic control. The first is over acquiring beliefs. The second is over maintaining beliefs. The third is over how we use our beliefs. I am chiefly concerned with the first locus of doxastic control in this essay, but I will say something about the second locus along the way. Also, I will only consider one way we might exercise control over acquiring beliefs. Specifically, I will present an argument against direct doxastic voluntarism (DDV). By “DDV” I mean to refer to the thesis that it is conceptually possible for agents to consciously exercise the same sort of direct voluntary control over coming to acquire a doxastic attitude—such as belief, suspension of belief, and disbelief—that they exercise over uncontroversial basic actions. If DDV is correct, then coming to believe can be a basic action-type. DDV, or something very close to it, was Bernard Williams’ target in his 1973 paper, “Deciding to Believe.” Williams’s argument is widely regarded as having been a failure. But I think that Williams was on to something in his paper. Hence, in this paper, while I do not attempt to resurrect Williams’s argument, I develop and defend a revised argument for a thesis that is quite close to Williams’s. I will proceed as follows. First, I will discuss Bernard Williams’ (1973) failed attempt at showing that DDV is conceptually impossible. This will be followed by a discussion of some constraints on our belief-forming activities. I will then clarify my target a bit more than Williams does in his original paper. Finally, I will present my own argument against the conceptual possibility of DDV. (shrink)

A number of general points behind the story of this paper may be worth setting out separately, now that we have come to the end.There is perhaps one obvious omission to be addressed right away. Although the word “information” has occurred throughout this paper, it must have struck the reader that we have had nothing to say on what information is. In this respect, our theories may be like those in physics: which do not explain what “energy” is (a notion (...) which seems quite similar to “information” in several ways), but only give some basic laws about its behaviour and transmission.The eventual recommendation made here has been to use a broad type-theoretic framework for studying various more classical and more dynamic notions of proposition in their interaction. This is not quite the viewpoint advocated by many current authors in the area, who argue for a whole-sale switch from a ‘static’ to a ‘dynamic’ perspective on propositions. This is not the place, however, to survey the conceptual arguments for and against such a more radical move.This still leaves many questions about possible reductions from one perspective to another. For instance, it would seem that classical systems ought to serve as a ‘limiting case’, which should still be valid after procedural details of some cognitive process have been forgotten. There are various ways of implementing the desired correspondence: e.g. by considering extreme cases with ⫅ equal to identity, or, in the pure relational algebra framework by considering only pairs (x, x). What we shall want then are reductions of dynamic logics, in those special cases, to classical logic. But perhaps also, more sophisticated views are possible. How do we take a piece of ‘dynamic’ prose, remove control instructions and the like, and obtain a piece of ‘classical’ text, suitable for inference ‘in the light of eternity’?There is also a more technical side to the matter of ‘reduction’. By now, Logic has reached such a state of ‘inter-translatability’ that almost all known variant logics can be embedded into each other, via suitable translations. In particular, once an adequate semantic has been given for a new system, this usually induces an embedding into standard logic: as we know, e.g., for the case of Modal Logic. Like-wise, all systems of dynamic interpretation or inference proposed so far admit of direct embedding into an ordinary ‘static’ predicate logic having explicit transition predicates (cf. van Benthem 1988b). Thus, our moral is this. The issue is not whether the new systems of information structure or processing are essentially beyond the expressive resources of traditional logical systems: for, they are not. The issue is rather which interesting phenomena and questions will be put into the right focus by them.The next broad issue concerns the specific use of the perspective proposed here, vis-à-vis concrete proposals for information-oriented or dynamic semantics. The general strategy advocated here is to locate some suitable base calculus and then consider which ‘extras’ are peculiar to the proposal. For instance, this is the spirit in which modal S4 would be a base logic of information models, and intuitionistic logicthe special theory devoting itself to upward persistent propositions. Or, with the examples in Section 4.1, the underlying base logic is our relational algebra, whereas, say, ordinary updates then impose special properties, such as ‘idempotence’: $$xRy \Rightarrow yRy$$ Does this kind of application presuppose the existence of one distinguished base logic, of which all others are extensions? This would be attractive-and some form of relational algebra or linear logic might be a reasonable candidate. Nevertheless, the enterprise does not rest on this outcome. What matters is an increased sensitivity to the ‘landscape’ of dynamic logics, just as with the ‘Categorial Hierarchy’ in Categorial Grammar (cf. van Benthem 1989a, 1991) where the family of logics with their interconnections seems more important than any specific patriarch.Finally, perhaps the most important issue in the new framework is the possibility of new kinds of questions arising precisely because of its differences from standard logic. Notably, given the option of regarding propositions as programs, it will be of interest to consider systematically which major questions about programming languages now make sense inside logic too.EXAMPLE. Correctness. When do we have $$\left[\kern-0.15em\left[ \pi \right]\kern-0.15em\right](\left[\kern-0.15em\left[ A \right]\kern-0.15em\right]) \subseteq \left[\kern-0.15em\left[ B \right]\kern-0.15em\right]$$ for (s, t) propositions A, B and a dynamic (s, (s, t)) proposition π?Program Synthesis. Which dynamic proposition will take us from an information state satisfying A to one satisfying B? (This question needs refinement, lest there be trivial answers.)Determinism. Which propositions as programs are deterministic, in the sense of defining single-valued functions from states to states?Querying. What does it mean to ask for information in the present setting? (Again, individual types referring to e will be crucial here.)This is not merely an agenda for wishful thinking. Within Logic, there are various ways of introducing such concerns into semantics, especially, using tools from Automata Theory. (See van Benthem 1989c for further discussion of such computational perspectives in ‘cognitive programming’.)At least if one believes that ‘dynamics’ is of the essence in cognition (rather than a mere interfacing problem between the halls of eternal truth and the noisy streets of reality), the true test for the present enterprise is the development of a significant new research program not merely copying the questions of old.

Currently, global society is delicately poised on a civilisational threshold similar to that of the feudal era. This is a time when outmoded institutions, values, and systems of thought and their associated dogmas are ripe for transcendence by more relevant systems of organization and knowledge (Davidson, 2000). The foundations of the modern era (including modern educational institutions) are under sharp scrutiny; the fragmentation of nature, society and self is evidence of the cracks in the foundations. In times of crises old (...) questions often come to the fore. For example, as environmental problems reach unprecedented levels the perennial existential question of how we should live is emerging once more. So too are educational questions such as what and how we should learn. But, times of crises also present new opportunities, create fresh imaginings and alternative meanings, metaphors and languages.In this paper I wish to appraise sustainability (and its epithets such as development) as a new discourse that emerged in the late 20th century in response to the psycho-socio-environmental crises of the time. I shall also examine the (in)capacity of disciplinary knowledge and traditional scholarship to respond to the complex and pressing problems of contemporary society. Finally, I will critically discuss the role that new modes of knowledge production, an expanded view of scholarship and alternative metaphors might play in (re)imagining the university's role in sustainability education.

We call attention to an underappreciated way in which non-epistemic values influence evidence evaluation in science. Our argument draws upon some well-known features of scientific modeling. We show that, when scientific models stand in for background knowledge in Bayesian and other probabilistic methods for evidence evaluation, conclusions can be influenced by the non-epistemic values that shaped the setting of priorities in model development. Moreover, it is often infeasible to correct for this influence. We further suggest that, while this value influence (...) is not particularly prone to the problem of wishful thinking, it could have problematic non-epistemic consequences in some cases. (shrink)

The following four assumptions plausibly describe the ideal rational agent. (1) She knows what her beliefs are. (2) She desires to believe only truths. (3) Whenever she desires that P → Q and knows that P, she desires that Q. (4) She does not both desire that P and desire that ~P, for any P. Although the assumptions are plausible, they have an implausible consequence. They imply that the ideal rational agent does not believe and desire contradictory propositions. She neither (...) desires the world to be any different than she thinks it is, nor thinks it is any different than she desires it to be. The problem of preserving our intuitions about desire, without embracing the implausible conclusion, is what I call “the Wishful Thinking Puzzle.” In this paper, I examine how this puzzle arises, and I argue that it is surprisingly difficult to solve. Even the decision theoretic conception of desire is not immune to the puzzle. One approach, the contrastive conception of desire, does avoid the puzzle without being ad hoc, but it remains too inchoate to win our full confidence. (shrink)

Climate change confronts us with our most pressing challenges today. The global consensus is clear that human activity is mostly to blame for its harmful effects, but there is disagreement about what should be done. While no shortage of proposals from ecological footprints and the polluter pays principle to adaptation technology and economic reforms, each offers a solution – but is climate change a problem we can solve? In this provocative new book, these popular proposals for ending or overcoming (...) the threat of climate change are shown to offer no easy escape and each rest on an important mistake. Thom Brooks argues that a future environmental catastrophe is an event we can only delay or endure, but not avoid. This raises new ethical questions about how we should think about climate change. How should we reconceive sustainability without a status quo? Why is action more urgent and necessary than previously thought? What can we do to motivate and inspire hope? Many have misunderstood the kind of problem that climate change presents – as well as the daunting challenges we must face and overcome. Climate Change Ethics for an Endangered World is a critical guide on how we can better understand the fragile world around us before it is too late. This innovative book will be of great interest to students and scholars of climate change, climate justice, environmental policy and environmental ethics. "This book offers a rare combination of tough-mindedness, analytic rigor, and passion as it tackles the greatest challenge of our time―climate change. For Brooks, it’s past time to acknowledge that climate change cannot be solved though the careful selection of good polices. Climate change is an unavoidable tragedy that we must endure but may be able to survive. Offering a program that emphasizes flexibility and adaptation, Brooks brings original insights to a debate that too long has been bogged down in wishful thinking and empty scholasticism."

Wishful thinking (WT) of Israeli voters was measured in the unprecedented event of three failing national elections repeated within one year. WT is considered as Type 1 fast/intuitive thinking leading to bias. A novel method for measuring WT – including relevant campaign information and distinguishing between “WT for self” and “WT for others” – was introduced. WT components of voters in leading and trailing camps were compared across the three elections to examine whether patterns would be consistent (...) or haphazard. Despite the presumed uncontrolled nature of WT, the patterns were not haphazard but rather consistent. We also tried to debias WT by applying a novel variation of incentive intervention to shift respondents from fast thinking to slow, rational Type 2 thinking. Unlike past studies, the method was extremely effective in debiasing WT and leading to realistic predictions. However, this was true only for self-WT and not for WT for others. (shrink)

This article focuses both on the multifarious personality of Jos Decorte and on the primary themes that recur throughout his writings in light of his death in a tragic traffic accident fourteen years ago. Being a scholar in medieval philosophy, Decorte’s main purpoie was not only to rehabilitate the pivotal role that each of the aforementioned thinkers played within the evolution of medieval philosophy, but to apply their insights to contemporary problems as well. To that end, he wished to transform (...) Henry of Ghent’s ontology of relations and Cusanus’ conjectural ontology into subtler forms that could be adjusted to the predicaments of twentieth century philosophy. Wavering between the tradition of metaphysics and that of negative theology, he defined his own project as striving towards an ideal that, albeit not rationally grounded, could give rise to different and interrelated ramifications of rationality. Finally, it is shown how that ideal was reflected in his strong engagement, alike in his personal and in academic life. (shrink)
