This paper proposes a new explanation for the paradoxes related to anthropic reasoning. Solutions to the Sleeping Beauty Problem and the Doomsday argument are discussed in detail. The main argument can be summarized as follows: -/- Our thoughts, reasonings and narratives inherently comes from a certain perspective. With each perspective there is a center, or using the term broadly, a self. The natural first-person perspective is most primitive. However we can also think and express from others’ (...) perspectives with a theory of mind. A perspective’s center could be unrelated to the topic of discussion so its de se thoughts need not to be considered, e.g. the perspective of an outside observer. Let’s call these the third-person perspective. First-person reasoning allows primitive self identification as I am inherently unique as the center of the perspective. Whereas from third-person perspective I am not fundamentally special comparing to others so a reference class of observers including me can be defined. It is my contention that reasonings from different perspectives should not mix. Otherwise it could lead to paradoxes even independent of anthropic reasoning. The paradoxes surrounding anthropic reasoning are caused by the aforementioned perspective mix. Regarding the sleeping beauty problem the correct answer should be double halving. Lewisian halving and thirding uses unique reasonings from both first and third-person perspectives. Indexical probabilities such as “the probability that this is the first awakening” or “the probability of me being one of the first 100 billion human beings” also mixes first- and third-person reasonings. Therefore invalid. Readers against perspectivism may disagree with point 1 and suggest we could reason in objective terms without the limit of perspectives. My argument is compatible with this belief. Objective reasoning would be analytically identical to the third-person perspective. My argument would become that objective reasoning and perspective reasonings should not mix. In the following I would continue to use “third-person perspective” but readers can switch that to “objective reasoning” if they wish so. (shrink)

Objective reasons are given by the facts. Subjective reasons are given by one’s perspective on the facts. Subjective reasons, not objective reasons, determine what it is rational to do. In this paper, I argue against a prominent account of subjective reasons. The problem with that account, I suggest, is that it makes what one has subjective reason to do, and hence what it is rational to do, turn on matters outside or independent of one’s perspective. After explaining and (...) establishing this point, I offer a novel account of subjective reasons which avoids the problem. (shrink)

This article considers two important problems for the idea that what we ought to do is determined by the balance of competing reasons. The problems are distinct, but the object of the article is to explore how they admit of a single solution. It is a consequence of this solution that objective reasons—facts that count in favor—are in an important sense less objective than they have consistently been assumed to be. This raises but does not answer the question as to (...) what evidence we ever had that reasons are as objective as has been assumed. (shrink)

Together we can achieve things that we could never do on our own. In fact, there are sheer endless opportunities for producing morally desirable outcomes together with others. Unsurprisingly, scholars have been finding the idea of collective moral obligations intriguing. Yet, there is little agreement among scholars on the nature of such obligations and on the extent to which their existence might force us to adjust existing theories of moral obligation. What interests me in this paper is the perspective (...) of the moral deliberating agent who faces a collective action problem, i.e. the type of reasoning she employs when deciding how to act. I hope to show that agents have collective obligations precisely when they are required to employ ‘we-reasoning’, a type of reasoning that differs from I-mode, best response reasoning, as I shall explain below. More precisely, two (or more) individual agents have a collective moral obligation to do x if x is an option for action that is only collectively available (more on that later) and each has sufficient reason to rank x highest out of the options available to them.

Dale Dorsey’s wide-ranging A Theory of Prudence contains ideas and arguments worthy of our attention on quite a variety of self-interest-related normative topics. In this essay I focus on Dorsey’s theory of prudential rationality, which is designed to deliver a negative answer to this essay’s titular question. Dorsey’s negative answer may be more intuitive, but I believe the positive answer is more defensible. From the perspective of prudence, it is just as reasonable to change your desires to fit the (...) world as it is to change the world to fit your desires. (shrink)

‘Reasonable wrongdoers’ reasonably, but wrongly, take themselves to act permissibly. Many responsibility theorists assume that since we cannot reasonably expect these wrongdoers to behave differently, they are not blameworthy. These theorists impose a Reasonable Expectation Condition on blame. I argue that reasonable wrongdoers may be blameworthy. It is true that we often excuse reasonable wrongdoers, but sometimes this is because we do not regard their behavior as objectionable in a way that makes blame appropriate. As such, these cases do not (...) support the proposition that wrongdoers are excused just because they reasonably take themselves to act permissibly. For the relevant support, we should consider cases in which a reasonable wrongdoer’s behavior is unambiguously objectionable by our moral lights. But here again we fail to find decisive support for the Reasonable Expectation Condition since it is not obvious—independent of a prior commitment to this condition—that such wrongdoers are not blameworthy. After laying out the above argument, as well as offering a positive account of why reasonable wrongdoers are sometimes blameworthy, I turn to consider objections. The most important of these is that it is simply unfair to blame those who reasonably take themselves to behave unobjectionably and who cannot be expected to behave otherwise. (shrink)

In recent years, the human ability to reasoning about mental states of others in order to explain and predict their behavior has come to be a highly active area of research. Researchers from a wide range of fields { from biology and psychology through linguistics to game theory and logic{ contribute new ideas and results. This interdisciplinary workshop, collocated with the Thirteenth International Conference on Theoretical Aspects of Rationality and Knowledge (TARK XIII), aims to shed light on models of (...) social reasoning that take into account realistic resource bounds. People reason about other people's mental states in order to understand and predict the others' behavior. This capability to reason about others' knowledge, beliefs and intentions is often referred to as theory of mind. Idealized rational agents are capable of recursion in their social reasoning, and can reason about phenomena like common knowledge. Such idealized social reasoning has been modeled by modal logics such as epistemic logic and BDI (belief, desire, intention) logics and by epistemic game theory. However, in real-world situations, many people seem to lose track of such recursive social reasoning after only a few levels. The workshop provides a forum for researchers that attempt to analyze, understand and model how resource-bounded agents reason about other minds. (shrink)

This chapter develops and defends an account of reason: to reason is to scrutinize one’s attitudes by consulting the perspectives of other persons. The principal attraction of this account is its ability to vindicate the unique of authority of reason. The chapter argues that this conception entails that reasoning is a robustly social endeavor—that it is, in the first instance, something we do with other people. It is further argued that such social endeavors presuppose mutual respect on the part (...) of those participating in them. The account therefore yields a form of Kantian constructivism: we have an unconditional duty of respect for persons because such a duty is implicit in the very nature of reasoning. -/- . (shrink)

In this paper, I develop a theory of how claims about an agent’s normative reasons are sensitive to the epistemic circumstances of this agent, which preserves the plausible ideas that reasons are facts and that reasons can be discovered in deliberation and disclosed in advice. I argue that a plausible theory of this kind must take into account the difference between synchronic and diachronic reasons, i.e. reasons for acting immediately and reasons for acting at some later point in time. I (...) provide a general account of the relation between synchronic and diachronic reasons, demonstrate its implications for the evidence-sensitivity of reasons and finally present and defend an argument for my view.

This paper briefly outlines some advancements in paraconsistent logics for modelling knowledge representation and reasoning. Emphasis is given on the so-called Logics of Formal Inconsistency (LFIs), a class of paraconsistent logics that formally internalize the very concept(s) of consistency and inconsistency. A couple of specialized systems based on the LFIs will be reviewed, including belief revision and probabilistic reasoning. Potential applications of those systems in the AI area of KRR are tackled by illustrating some examples that emphasizes the (...) importance of a fine-tuned treatment of consistency in modelling reputation systems, preferences, argumentation, and evidence.

Thomas Kuhn’s depiction of scientific revolution has much in common with Charles Sanders Peirce’s portrayal of abductive reasoning, with each description outlining a template for the overthrow and reconstruction of contextual frameworks. Such upheavals are often ignited by a single individual and are frequently idiosyncratic and iconoclastic in nature. Accordingly, this essay explores the role autism plays in both scientific revolution and abductive reasoning, with an emphasis on the atypical perceptual characteristics that autistic individuals bring to the human (...) population, characteristics that are focused intensely on the underlying structural features to be found in the surrounding environment. Finally, the observation is made that the community-heavy practices of today's scientific world are systematically suppressing atypical perspectives, accounting for the current paucity of scientific revolution.

Morality is one of the most important issues for humans and a common concern of human beings. Talking about the importance of morality, prompts people to think about the question of why should we live morally? The answer to this question can be found among the various functions that thinkers have proposed for ethics, because if the agent’s knowledge confirms the usefulness of the action, then the agent will be motivated to do it. Therefore, the functions of an action can (...) be an answer to why the action is performed. One of the functions of moral life is to increase the chance of survival, which has been introduced by moral evolutionists. The question of the present article is: how much this function can create motivation for a person to perform a moral act? Can the agent’s knowledge that ethical life increases the chances of survival motivate her/him to observe moral values? Considering the challenge of not believing in resurrection and sacrificing life, and many problems in life and the difficulties of ethical life, it is concluded that although increasing the chance of survival can motivate a person to live morally, but just increasing the chances of survival is not worth accepting the costs of being moral and does not provide enough motivation to endure the hardships of moral life. Therefore, evolutionary ethics is facing the challenge of lack of explanatory power for moral motivations and cannot be accepted as a comprehensive theory in the field of moral motivation. (shrink)

Objections to the orthodox doctrine of an eternal hell often rely on arguments that it cannot be a person’s own fault that she ends up in hell. The paper summarizes and addresses three significant arguments which aim to show that it could not be any individual’s fault that they end up in hell. I respond to these objections by showing that those who affirm a classical picture of sin have Moorean reasons to reject these objections. That classical perspective holds (...) that all (serious) sin involves choosing eternal destiny apart from God and that no sin could possibly be caused by God. Consequently, it is necessary for ending up in hell that someone commit a serious sin, and it is sufficient for ending up damned that one persists forever in sin. Since the objections conflict with Moorean commitments central to the classical perspective, those who hold to such a classical perspective on sin would have good reason to reject all these arguments, which involve assumptions that would entail that such a perspective is false.

Reasons-based accounts of our normative conclusions face difficulties in distinguishing between what ought to be done and what is required. This article addresses this problem from a formal perspective. I introduce a rudimentary formalization of a reasons-based account and demonstrate that that the model faces difficulties in accounting for the distinction between oughts and requirements. I briefly critique attempts to distinguish between oughts and requirements by appealing to a difference in strength or weight of reasons. I then present a (...) formalized reasons-based account of permissions, oughts and requirements. The model exploits Joshua Gert (2004; 2007) and Patricia Greenspan’s (2005; 2007; 2010) suggestion that some reasons perform a purely justificatory function. I show that the model preserves the standard entailment relationships between requirements, oughts and permissions. (shrink)

This paper looks at whether it is possible to unify the requirements of rationality with the demands of normative reasons. It might seem impossible to do because one depends upon the agent’s perspective and the other upon features of the situation. Enter Reasons Perspectivism. Reasons perspectivists think they can show that rationality does consist in responding correctly to reasons by placing epistemic constraints on these reasons. They think that if normative reasons are subject to the right epistemic constraints, rational (...) requirements will correspond to the demands generated by normative reasons. While this proposal is prima facie plausible, it cannot ultimately unify reasons and rationality. There is no epistemic constraint that can do what reasons perspectivists would need it to do. Some constraints are too strict. The rest are too slack. This points to a general problem with the reasons-first program. Once we recognize that the agent’s epistemic position helps determine what she should do, we have to reject the idea that the features of the agent’s situation can help determine what we should do. Either rationality crowds out reasons and their demands or the reasons will make unreasonable demands. (shrink)

This article examines the evolution of the concept of existence in modern visual representation and reasoning, highlighting important milestones. In the late eighteenth century, during the so-called golden age of visual reasoning, nominalism reigned supreme and there was limited scope for existential import or individuals in logic diagrams. By the late nineteenth century, a form of realism had taken hold, whose existential commitments continue to dominate many areas in logic and visual reasoning to this day. Physical, metaphysical, (...) epistemological, and linguistic positions underlie both nominalist and realist views. Since the paradigmatic works on visual reasoning in the 1990s, formal diagram systems have been developed that revive either the nominalist or realist perspectives. Unlike in the nineteenth century, these are not motivated by philosophical views. Nevertheless, they may still have an impact on many areas of philosophy and science outside logic. (shrink)

Although feminists have spilled a great deal of ink criticizing Enlightenment conceptions of rationality, the time has come to consider constructing a positive account. Recent attempts to construct an account of rationality as a virtue concept reflect many feminist complaints concerning Enlightenment rationality, and, thus, I maintain that feminism should take seriously such a conception. Virtue rationality offers a more diverse account of rationality without sacrificing the fundamental normativity of the concept. Furthermore, the narrower concept of reasonableness, promises to provide (...) a ground for distinguishing among better and worse epistemic perspectives, which is a task critical to the success of the feminist project.

I will show that there are mainly two different, mutually contradictory approaches taken by philosophers in trying to answer the question: “Who or what is to blame for the Holocaust?” The first answer, offered by radical critics of Enlightenment (Adorno/Horkheimer, Saul, Heidegger), blames one of the following: Reason, Modernity, the State, Industrial Society, Bureaucratic Management and/or Technocratic Efficiency. On the other side, we have the answer given by liberal-democratic defenders of Enlightenment (Arendt, Habermas, Rawls): It claims the Holocaust was caused (...) the upsurge of anti-rational, irrational or pre-rational forces and a deep rejection of the humanistic principles and ethical values that underpin modernity. In this study, I want to analyze these two perspectives, comparing and contrasting their respective merits. (shrink)

Causal understanding is a defining characteristic of human cognition. Like many animals, human children learn to control their bodily movements and act effectively in the environment. Like a smaller subset of animals, children intervene: they learn to change the environment in targeted ways. Unlike other animals, children grow into adults with the causal reasoning skills to develop abstract theories, invent sophisticated technologies and imagine alternate pasts, distant futures and fictional worlds. In this Review, we explore the development of human-unique (...) causal learning and reasoning from evolutionary and ontogenetic perspectives. We frame our discussion using an ‘interventionist’ approach. First, we situate causal understanding in relation to cognitive abilities shared with non-human animals. We argue that human causal understanding is distinguished by its depersonalized (objective) and decontextualized (general) representations. Using this framework, we next review empirical findings on early human causal learning and reasoning and consider the naturalistic contexts that support its development. Then we explore connections to related abilities. We conclude with suggestions for ongoing collaboration between developmental, cross-cultural, computational, neural and evolutionary approaches to causal understanding. (shrink)

The debate over the meanings of indexical expressions has relied heavily on the method of counterexamples. This paper challenges that method by showing that purported counterexamples can often be explained away by appeal to perspective shifts. For these counterexamples to establish anything about indexical reference, we must identify the conditions under which theorists can legitimately appeal to perspective shifts. Some tests for semantic content are considered and it is argued that none of them can tell us when appeal (...) to perspective shift is admissible. The paper then considers how we should proceed if we become convinced that there is no way to identify the content of indexical expressions, offering reasons in favour of a nihilist conception of character over an epistemicist or pluralist conception.

Aquinas’s thought is often considered an exemplary balance between Christian faith and natural reason. However, it is not always sufficiently clear what such balance consists of. With respect to the relation between philosophical topics and the Christian faith, various scholars have advanced perspectives that, although supported by Aquinas’s texts, contrast one another. Some maintain that Aquinas elaborated his philosophical view without being under the influence of faith. Others believe that the Christian faith constitutes an indispensable component of Aquinas’s view; at (...) least when Aquinas focused on those statements that, though maintainable by mere reason, belong to the Christian revelation. In this essay I intend to show that the aforementioned perspectives can be reconciled on the basis of Aquinas’s concept of faith. If we do not limit ourselves to considering faith as the assent to the revealed truth, but also look at what leads the believer to assent—i.e., charity that unites the believer with God and is gratuitously conceded by God himself—then the relation between faith and reason appears to be twofold. On the one hand, the truths of faith cannot participate in the rational inquiry, because according to Aquinas faith lacks the evidence searched for by natural reason. On the other hand, since Aquinas holds that faith is the assent to the revelation due to the love for God that is granted by God himself, the believer will take faith as more certain than intellect and science, and the truths of faith will constitute the orientation and criterion of her/his rational investigation. The truths shall constitute orientation because the believer aims to confirm by reason what she/he already believes. They will also be criterion, because in case of a contradiction between rational arguments and revealed truths, reason must be considered mistaken and the rational investigation must start anew from the beginning.

Feminists note an association of arguing with aggression and masculinity and question the necessity of this connection. Arguing also seems to some to identify a central method of philosophical reasoning, and gendered assumptions and standards would pose problems for the discipline. Can feminine modes of reasoning provide an alternative or supplement? Can overarching epistemological standards account for the benefits of different approaches to arguing? These are some of the prospects for argumentation inside and outside of philosophy that feminists (...) consider. -/- The further concern is that the academic study of argumentation – in philosophy and other disciplines – has failed to account for the type of reasoning needed for social justice movements. What resources for addressing these concerns can be found in informal logic and interdisciplinary argumentation theory? Since part of the perceived problem derives from assuming that arguing is a contest, are more collaborative epistemological frameworks better? Can regular politeness or civility hedge against undesirable tendencies of argumentation? Can “critical thinking” pedagogy involving argument educations answer the needs of social justice? (shrink)

This paper presents a series of studies (total N=579) which demonstrate that folk judgments concerning the reasonableness of decisions and actions depend strongly on whether they engender positive or negative consequences. A particular decision is deemed more reasonable in retrospect when it produces beneficial consequences than when it produces harmful consequences, even if the situation in which the decision was taken and the epistemic circumstances of the agent are held fixed across conditions. This finding is worrisome for the law, where (...) the reasonable person standard plays a prominent role. The legal concept of reasonableness is outcome-insensitive: whether the defendant acted in a reasonable fashion or not depends exclusively on her context of action, no matter how things play out. Folk judgments of reasonableness are thus inconsistent with the legal concept of reasonableness. Problematically, in common law jurisdictions, the decision whether a defendant’s behavior was reasonable or not is frequently (though not necessarily) delegated to a lay jury. (shrink)

This paper concerns a specific epistemic feature of believing for a reason (e.g., believing that it will rain on the basis of the grey clouds outside). It has commonly been assumed that our access to such facts about ourselves is akin in all relevant respects to our access to why other people hold their beliefs. Further, discussion of self-intimation - that we are necessarily in a position to know when we are in certain conditions - has centred largely around mental (...) states. In contrast to both assumptions, this paper argues that believing for a reason is (at least) very nearly self-intimating: necessarily, if a subject believes that q for the reason that p, then, provided relevant conceptual and rational capacities, she is in a position to form a justified true belief that she believes that q for the reason that p. We should think this on the basis of the role that believing for a reason plays from the subjects’ perspective, and in particular, the way in which it intellegises one’s belief. (shrink)

This book presents a philosophical conception of logic -- "logical expressivism"-- according to which the role of logic is to make explicit reason relations, which are often neither monotonic nor transitive. It reveals new perspectives on inferential roles, sequent calculi, representation, truthmakers, and many extant logical theories.

Consider a terrible situation that too many women find themselves in: 85,000 women are raped in England and Wales alone every year. Many of these women do not bring their cases to trial. There are multiple reasons that they might not want to testify in the courts. The incredibly low conviction rate is one. Another reason, however, might be that these women do not want the fact that they were raped to become the most salient thing about them. More specifically, (...) they do not want it to be the thing that others attend to the most—that others find most noticeable and memorable. In this paper, I introduce the notion of ‘harmful salience perspectives’ to help to explain this and related phenomena. This refers either to attention on things that should not be salient, or not enough attention on things that deserve to be made salient. Following ideas within the feminist literature on objectification, I argue that we can be harmed when aspects of our identity that do not reflect our personhood—our agency, rationality, personality, and so on—are more prominent in the minds of others than aspects that do reflect our personhood. Crucially, these ways of attending do not need to implicate false beliefs and harmful ideologies to be harmful, but can be harmful in their own right. (shrink)

We propose a new account of collective moral obligation. We argue that several agents have a moral obligation together only if they each have (i) a context-specific capacity to view their situation from the group’s perspective, and (ii) at least a general capacity to deliberate about what they ought to do together. Such an obligation is irreducibly collective, in that it does not imply that the individuals have any obligations to contribute to what is required of the group. We (...) highlight various distinctive features of our account. One such feature is that moral obligations are always relative to an agential perspective. (shrink)

This paper investigates the logic of reasons. Its aim is to provide an analysis of the sentences of the form ‘p is a reason for q’ that yields a coherent account of their logical properties. The idea that we will develop is that ‘p is a reason for q’ is acceptable just in case a suitably defined relation of incompatibility obtains between p and ¬q. As we will suggest, a theory of reasons based on this idea can solve three challenging (...) puzzles that concern, respectively, contraposing reasons, conflicting reasons, and supererogatory reasons, and opens a new perspective on some classical issues concerning non-deductive inferences.

In this paper, I criticize the most prevalent positive argument for ethical nonnaturalism, the argument from ethical phenomenology. According to it, nonnatural entities are part of the best explanation of the phenomenology of ethical deliberation; therefore, nonnaturalism is true. -/- The argument from ethical phenomenology blinds out the external, empirically informed perspective on ethical deliberation. I argue that this is unwarranted for general methodological reasons: When starting to investigate any mental process — such as ethical deliberation — it is (...) reasonable to take into account, and try to reconcile, both the internal and the external perspective on the process. This renders the argument from ethical phenomenology methodologically flawed. The problem could be avoided if we already knew, somehow, that external evidence is irrelevant for the nature of ethical entities. Many nonnaturalists believe in this irrelevance because they take ethics to be "autonomous", "just too different", or the like. But the autonomy of ethics must itself be justified in a way that does not solely rely on internal insights — or else we are going in circles. I conclude that solely phenomenology-based arguments for nonnaturalism fail for methodological reasons. Consequently, nonnaturalists need to change their strategies and actively embrace the external perspective. (shrink)

Presuppositions are pragmatically considered as the conditions of the felicity of a speech act, or discourse move; however, the decision of setting the conditions of a move, which the hearer needs to accept in order to continue the dialogue, can be thought of as a speech act of a kind. The act of presupposing depends on specific conditions and in particular on the possibility of the hearer to reconstruct and accept the propositional content. These pragmatic conditions lead to epistemic considerations: (...) How can the speaker know that the hearer can reconstruct and accept a presupposition? A possible answer can be found in an argumentative approach grounded on the notion of presumptive reasoning. On this perspective, by presupposing the speaker advances a tentative conclusion about what the hearer may accept, hold, or know proceeding from factual, linguistic, and epistemic rules of presumption.

We live in an age of evidence-based healthcare, where the concept of evidence has been avidly and often uncritically embraced as a symbol of legitimacy, truth, and justice. By letting the evidence dictate healthcare decision making from the bedside to the policy level, the normative claims that inform decision making appear to be negotiated fairly—without subjectivity, prejudice, or bias. Thus, the term ‘‘evidence-based’’ is typically read in the health sciences as the empirically adequate standard of reasonable practice and a means (...) for increasing certainty. Supporters believe that evidence-based medicine (EBM) can introduce rational order to the deliberative processes of healthcare decision making. It is perhaps puzzling, then, to come across critical perspectives (typically arising from the humanities and the more theory-driven social sciences) raising concerns about a seeming technogovernance being introduced by this deferral to the evidence where power interests can be obfuscated by way of technical resolve. The critics holding this minority view argue that technological solutions to problems of knowledge and practice cannot replace medicine’s normative content. Against EBM’s democratic leanings toward transparency and accountability, medical criteria alone cannot decide valueladen ethically charged decisions. This paper attempts to explain and evaluate this important debate in the philosophy of medicine, focusing specifically on the dispute over 'evidence-based women's health'. (shrink)

Kant’s notion of (what I will call) rational sympathy solves a problem about how we can voluntarily fulfill our imperfect duty to adopt those ends of others which have value only because they have been set by rational agents, ends which I will refer to as merely permissible ends (MPEs). Others’ MPEs are individuated in terms of their own concepts of their MPEs, and we can only adopt their MPEs in terms of their concepts, since to adopt them in terms (...) of different concepts would be to adopt different ends. Others’ concepts of their MPEs may contain marks of the first person, and should contain no marks of law apart from permissibility. Rational sympathy allows us to adopt ends individuated in terms of concepts with marks of these kinds because rational sympathy allows us to voluntarily adopt others’ first-person perspectives in imagination, and to voluntarily shape our contingent feelings so that such concepts motivate us despite their underdetermination by law.

For a variety of reasons, Hegel's theory of the estates remains an unexpected and unappreciated feature of his practical philosophy. In fact, it is the key element of his social philosophy, which grounds his more properly political philosophy. Most fundamentally, it plays this role because the estates provide the forms of visibility required by Hegel's distinctive theory of self-determination, and so the estates constitute conditions for the possibility of human agency as such. With respect to political agency in particular, this (...) ramifies into the view that the estates are social preconditions for legal and political practices, forms of political participation in their own right, and conditions of possibility of moderate government (three functions also attributed to the estates by Montesquieu).

The role of reason, and its embodiment in philosophical-scientific theorizing, is always a troubling one for religious traditions. The deep emotional needs that religion strives to satisfy seem ever linked to an attitudes of acceptance, belief, or trust, yet, in its theoretical employment, reason functions as a critic as much as it does a creator, and in the special fields of metaphysics and epistemology its critical arrows are sometimes aimed at long-standing cherished beliefs. Understandably, the mere approach to these beliefs (...) through organized philosophical activity, however well-intended, is viewed with suspicion by ecclesiastical authorities and the devout. The attitude towards philosophical inquiry on the part of the Islamic religious community might be thought to typify this reaction. As one of the great prophetic religions, the self-avowed image of Islam is of a tradition which already possesses the truth as set forth in the divine revelation of the Qur'an. What need is there for philosophizing on fundamental matters, e.g., the ultimate nature of reality, the foundations of morality, the modes whereby the divine is connected with the temporal? The structure of creation is already made clear, the "straight path" for living already manifest. how can philosophical activity be anything but a source of divisive controversy, for as it turns its gaze to the foundations upon which the Shari`a' (Islamic Law) rests, or to the grounds for religious belief itself, it cannot avoid turning up alternative viewpoints, different perspectives on divine revelation, noting various weaknesses in received 1 interpretations? In short, isn't the practice of philosophy a threat to Islam's promise of providing a comprehensive way of living devoid of skepticism and uncertainty about the place of a human in God's creation and his or her role in the 'umma (Islamic community)? This problem is not unique to Islam, nor is it a new one within Islam. We know that it has been debated by Islamic thinkers since the translations of the Greek philosophers began to appear in an organized Islamic world during the 8th Century A.. (shrink)

This chapter lays out a case that with the proper perspective on the place of epistemology within normative inquiry more generally, it is possible to appreciate what was on the right track about some of the early approaches to the analysis of knowledge, and to improve on the obvious failures which led them to be rejected. Drawing on more general principles about reasons, their weight, and their relationship to justification, it offers answers to problems about defeat and the conditional (...) fallacy that plagued early defeasibility analyses of knowledge and offers a sketch of a contemporary alternative that is motivated by the idea that knowledge requires the right kind of “match” between objective and subjective factors.

There is a massive amount of severe suffering and death in the world, and much of this suffering and death is out of our control. The amount and severity of suffering and death in the world can be used to make an argument for (or elicit a reaction against) the existence of God: if God—an all-powerful, all-knowing, and all-good being—exists, God would not allow such massive amounts of suffering and death. I'll propose a line of response that begins by exploring (...) what would be involved in taking a new perspective on the suffering and death in the world. I then argue that there is no good reason not to take that new perspective. If this is correct, the argument from (or reaction to) suffering and death to the conclusion that God doesn't exist has lost much of its force; an argument that seems forceful from one perspective is weak from a different perspective that is just as reasonable, or more reasonable, to take.

Many tasks in statistical and causal inference can be construed as problems of entailment in a suitable formal language. We ask whether those problems are more difficult, from a computational perspective, for causal probabilistic languages than for pure probabilistic (or “associational”) languages. Despite several senses in which causal reasoning is indeed more complex—both expressively and inferentially—we show that causal entailment (or satisfiability) problems can be systematically and robustly reduced to purely probabilistic problems. Thus there is no jump in (...) computational complexity. Along the way we answer several open problems concerning the complexity of well-known probability logics, in particular demonstrating the ${\exists \mathbb {R}}$ -completeness of a polynomial probability calculus, as well as a seemingly much simpler system, the logic of comparative conditional probability.

Decision theory explains weakness of will as the result of a conflict of incentives between different transient agents. In this framework, self-control can only be achieved by the I-now altering the incentives or choice-sets of future selves. There is no role for an extended agency over time. However, it is possible to extend game theory to allow multiple levels of agency. At the inter-personal level, theories of team reasoning allow teams to be agents, as well as individuals. I apply (...) team reasoning at the intra-personal level, taking the self as a team of transient agents over time. This allows agents to ask, not just “what should I-now do?’, but also ‘What should I, the person over time do?’, which may enable agents to achieve self-control. The resulting account is Aristotelian in flavour, as it involves reasoning schemata and perception, and it is compatible with some of the psychological findings about self-control. (shrink)

Contemporary reasoning about health is infused with the work products of experts, and expert reasoning about health itself is an active site for invention and design. Building on Toulmin’s largely undeveloped ideas on field-dependence, we argue that expert fields can develop new inference rules that, together with the backing they require, become accepted ways of drawing and defending conclusions. The new inference rules themselves function as warrants, and we introduce the term “warranting device” to refer to an assembly (...) of the rule plus whatever material, procedural, and institutional resources are required to assure its dependability. We present a case study on the Cochrane Review, a new method for synthesizing evidence across large numbers of scientific studies. After reviewing the evolution and current structure of the device, we discuss the distinctive kinds of critical questions that may be raised around Cochrane Reviews, both within the expert field and beyond. Although Toulmin’s theory of field-dependence is often criticized for its relativism, we find that, as a matter of practical fact, field-specific warrants do not enjoy immunity from external critique. On the contrary, they can be opened to evaluation and critique from any interested perspective. (shrink)

In the first part of the paper, Gaus’ ground for the ideal of persons as free and equal is described. Doubts are raised about the appropriateness of the use of his account of this ideal as endogenous to our moral practice. Th e worries are related to the use of the concept of having a reason that Gaus makes in his book, as well as to the aptness of his account of our moral practice from the viewpoint of our moral (...) phenomenology. Some doubts are raised in relation to the pertinence of Gaus’ concept of having a reason from the perspective of the motivation of the public reason project. In the second part of the paper, a summary is off ered of Gaus’ model of public justification and some of its consequences are discussed. Th e primary intention here is to show that, contrary to Gaus’ view, egalitarian liberalism, and not classical liberalism, is the most appropriate result of such a model of justification. (shrink)

Cognitive scientists used to deem reasoning either as a higher cognitive process based on the manipulation of abstract rules or as a higher cognitive process that is stochastic rather than involving abstract rules. I maintain that these different perspectives are closely intertwined with a theoretical and methodological endorsement of either cognitivism or connectionism. Cognitivism and connectionism represent two prevailing and opposed paradigms in cognitive science. I aim to extoll the virtues of connectionist models of enthymematic reasoning by following (...) means: via the phenomenon of creative enthymeme, viz. the inference where one cannot even articulate the missing premise, I introduce a connectionist mechanism of pattern recognition as underlying expertise; via Gestalt switch or Gestalt click, I demonstrate how differences in pattern recognition of an expert and a novice can be construed as qualitatively different, and not merely a matter of faster reasoning.

Book synopsis: This collection of previously unpublished essays presents the newest developments in the thought of international scholars working on the explanation of action. The contributions focus on a wide range of interlocking issues relating to agency, deliberation, motivation, mental causation, teleology, interprative explanation and the ontology of actions and their reasons. Challenging numerous current orthodoxies, and offering positive suggestions from a variety of different perspectives, this book provides essential reading for anyone interested in the explanation of action.

Standpoint logic is a recently proposed formalism in the context of knowledge integration, which advocates a multi-perspective approach permitting reasoning with a selection of diverse and possibly conflicting standpoints rather than forcing their unification. In this paper, we introduce nested sequent calculi for propositional standpoint logics---proof systems that manipulate trees whose nodes are multisets of formulae---and show how to automate standpoint reasoning by means of non-deterministic proof-search algorithms. To obtain worst-case complexity-optimal proof-search, we introduce a novel technique (...) in the context of nested sequents, referred to as "coloring," which consists of taking a formula as input, guessing a certain coloring of its subformulae, and then running proof-search in a nested sequent calculus on the colored input. Our technique lets us decide the validity of standpoint formulae in CoNP since proof-search only produces a partial proof relative to each permitted coloring of the input. We show how all partial proofs can be fused together to construct a complete proof when the input is valid, and how certain partial proofs can be transformed into a counter-model when the input is invalid. These "certificates" (i.e. proofs and counter-models) serve as explanations of the (in)validity of the input. (shrink)

This paper studies a family of monotonic extensions of first-order logic which we call modulated logics, constructed by extending classical logic through generalized quantifiers called modulated quantifiers. This approach offers a new regard to what we call flexible reasoning. A uniform treatment of modulated logics is given here, obtaining some general results in model theory. Besides reviewing the “Logic of Ultrafilters”, which formalizes inductive assertions of the kind “almost all”, two new monotonic logical systems are proposed here, the “Logic (...) of Many” and the “Logic of Plausibility”, that characterize assertions of the kind “many”, and “for a good number of”. Although the notion of simple majority (“more than half”) can be captured by means of a modulated quantifier semantically interpreted by cardinal measure on evidence sets, it is proven that this system, although sound, cannot be complete if checked against the intended model. This justifies the interest on a purely qualitative approach to this kind of quantification, what is guaranteed by interpreting the modulated quantifiers as notions of families of principal filters and reduced topologies, respectively. We prove that both systems are conservative extensions of classical logic that preserve important properties, such as soundness and completeness. Some additional perspectives connecting our approach to flexible reasoning through modulated logics to epistemology and social choice theory are also discussed. (shrink)

I show why Michael Friedman’s idea that we should view new constitutive frameworks introduced in paradigm change as members of a convergent series introduces an uncomfortable tension in his views. It cannot be justified on realist grounds, as this would compromise his Kantian perspective, but his own appeal to a Kantian regulative ideal of reason cannot do the job either. I then explain a way to make better sense of the rationality of paradigm change on what I take to (...) be Friedman’s own terms. (shrink)

This book investigates law's interaction with practical reasons. What difference can legal requirements—e.g. traffic rules, tax laws, or work safety regulations—make to normative reasons relevant to our action? Do they give reasons for action that should be weighed among all other reasons? Or can they, instead, exclude and take the place of some other reasons? The book critically examines some of the existing answers and puts forward an alternative understanding of law's interaction with practical reasons. -/- At the outset, two (...) competing positions are pitted against each other: Joseph Raz's view that (legitimate) legal authorities have pre-emptive force, namely that they give reasons for action that exclude some other reasons; and an antithesis, according to which law-making institutions (even those that meet prerequisites of legitimacy) can at most provide us with reasons that compete in weight with opposing reasons for action. These two positions are examined from several perspectives, such as justified disobedience cases, law's conduct-guiding function in contexts of bounded rationality, and the phenomenology associated with authority. -/- It is found that, although each of the above positions offers insight into the conundrum at hand, both suffer from significant flaws. These observations form the basis on which an alternative position is put forward and defended. According to this position, the existence of a reasonably just and well-functioning legal system constitutes a reason that fits neither into a model of ordinary reasons for action nor into a pre-emptive paradigm—it constitutes a reason to adopt an (overridable) disposition that inclines its possessor towards compliance with the system's requirements.

An account of the development of temporal understanding is proposed which links such understanding with the development of episodic memory. We distinguish between different ways of representing time in terms of the kinds of temporal frameworks they involve. Distinctions are made between frameworks that are perspectival or nonperspectival and those that represent recurrent sequences or particular times. Even primitive temporal understanding integrates both perspectival and nonperspectival components. However, since early frameworks are event-based and localized, they are not yet sufficient for (...) episodic memory in that they do not enable the child to think of events as having occurred at particular points in time. We describe the emergence of new kinds of frameworks in terms of the development of temporal decentering. Two levels of temporal decentering are distinguished, with the higher level involving an appreciation of how event representations depend on one's temporal perspective. (shrink)

Christopher Hookway has been influential in promoting engagement with pragmatist and naturalist perspectives from classical and contemporary American philosophy. This book reflects on Hookway’s work on the American philosophical tradition and its significance for contemporary discussions of the understanding of mind, meaning, knowledge, and value. -/- Hookway’s original and extensive studies of Charles S. Peirce have made him among the most admired and frequently referenced of Peirce’s interpreters. His work on classical American pragmatism has explored the philosophies of William James, (...) John Dewey, and Josiah Royce, and examined the influence of pragmatist ideas outside of the United States. Additionally, Hookway has participated in a number of celebrated exchanges with some of the most high-profile figures of twentieth- and twenty-first-century philosophy, including Karl-Otto Apel, Philip Pettit, Hilary Putnam, and W.V.O. Quine, through which his treatments of a large range of topics in epistemology and the philosophies of mind and language have been developed and promoted. The chapters in this book—which include contributions from several of Hookway’s former students and colleagues—include studies of Hookway’s engagement with the works of Peirce, James, and Dewey, his contributions to virtue epistemology, and his discussions of hope and pragmatist metaphysics. -/- Pragmatic Reason will be of interest to researchers and advanced students working on American philosophy, the history of analytic philosophy, and epistemology.

Mathematicians often speak of conjectures as being confirmed by evidence that falls short of proof. For their own conjectures, evidence justifies further work in looking for a proof. Those conjectures of mathematics that have long resisted proof, such as the Riemann hypothesis, have had to be considered in terms of the evidence for and against them. In recent decades, massive increases in computer power have permitted the gathering of huge amounts of numerical evidence, both for conjectures in pure mathematics and (...) for the behavior of complex applied mathematical models and statistical algorithms. Mathematics has therefore become (among other things) an experimental science (though that has not diminished the importance of proof in the traditional style). We examine how the evaluation of evidence for conjectures works in mathematical practice. We explain the (objective) Bayesian view of probability, which gives a theoretical framework for unifying evidence evaluation in science and law as well as in mathematics. Numerical evidence in mathematics is related to the problem of induction; the occurrence of straightforward inductive reasoning in the purely logical material of pure mathematics casts light on the nature of induction as well as of mathematical reasoning.

The thesis that smells are objective and independent of perceivers may seem to be in tension with the phenomenon of perceptual variation. In this paper, I argue that there are principled reasons to think that perceptual variation is not a threat to objectivism about smells and is indeed integral to our perceptual relation to the objective world. I first distinguish various kinds of perceptual variation, and argue that the most challenging cases for the objectivist are those where an odourant smells (...) different in different conditions or to different perceivers but the odourant does not change, and there is neither misperception nor a simple failure to perceive a smell. I then argue that there is an independently plausible conception of olfactory experience on which even these challenging cases do not pose a threat to objectivism about smells. Following Kalderon’s work in the domain of colour perception, I argue that olfactory perception provides us with a partial perspective on the smells around us, where this perspective is constrained by the conditions of perception as well as by features of the perceiver. Within this framework, we can allow that perceivers with different sensitivities, or the same perceiver in different conditions, genuinely perceive the same objective smell even though this smell appears different to them. In turn, smells are best understood as qualitatively complex entities, different aspects of which can become perceptually available in different conditions and to different perceivers. (shrink)
