Contrastivism about reasons is the view that ‘reason’ expresses a relation with an argument place for a set of alternatives. This is in opposition to a more traditional theory on which reasons are reasons for things simpliciter. I argue that contrastivism provides a solution to a puzzle involving reason claims that explicitly employ ‘rather than’. Contrastivism solves the puzzle by allowing that some fact might be a reason for an action out of one (...) set of alternatives without being a reason for that action out of a different set of alternatives. (shrink)

Contrastivism about ‘ought’ holds that ‘ought’ claims are relativized, at least implicitly, to sets of mutually exclusive but not necessarily jointly exhaustive alternatives. This kind of theory can solve puzzles that face other linguistic theories of ‘ought’, via the rejection or severe restriction of principles that let us make inferences between ‘ought’ claims. By rejecting or restricting these principles, however, the contrastivist takes on a burden of recapturing acceptable inferences that these principles let us make. This paper investigates (...) the extent to which a contrastivist can do this. (shrink)

A promising but underexplored view about normative reasons is contrastivism, which holds that considerations are fundamentally reasons for things only relative to sets of alternatives. Contrastivism gains an advantage over non-contrastive theories by holding that reasons relative to different sets of alternatives can be independent of one another. But this feature also raises a serious problem: we need some way of constraining this independence. I develop a version of contrastivism that provides the needed (...) constraints, and that is independently motivated by the widespread idea that reasons involve the promotion of various kinds of objectives.

Despite myriad controversies about reasons, two theses are frequently taken for granted: (i) reasons are sources of normative support for actions, attitudes, etc; and (ii) reasons, at least in simple, paradigmatic cases, consist in atomic facts. Call this conjunction “the atomic view.” Against this, we advocate what we call “the cluster view,” on which even in the simplest cases, the normative support for an action or attitude is typically provided by a whole cluster of facts. Moreover, (...) many of these facts are on an explanatory par—they each play the same kind of role in explaining why there is normative support for the action or attitude in question. We show that presupposition of the atomic view generates unnecessary (psuedo-)puzzles⁠—about topics such as rationality, moral worth, and doxastic justification⁠—that can be largely (dis)solved with the cluster view in place. The cluster view’s ability to do this constitutes an argument in its favor, beyond intuitive considerations that we also adduce. (shrink)

Here we focus on two questions: What is the proper semantics for deontic modal expressions in English? And what is the connection between true deontic modal statements and normative reasons? Our contribution towards thinking about the first, which makes up the bulk of our paper, considers a representative sample of recent challenges to a Kratzer-style formal semantics for modal expressions, as well as the rival views—Fabrizio Cariani’s contrastivism, John MacFarlane’s relativism, and Mark Schroeder’s ambiguity theory—those challenges are (...) thought to motivate. These include the Professor Procrastinate challenge to Inheritance (the principle that ‘If ought p and p entails q, then ought q), as well as Parfit’s miners puzzle regarding information-sensitive deontic modals. Here we argue that a Kratzer-style view is able to meet all of the challenges we’ll consider. In addition, we’ll identify challenges for each of those rival views. Our overall conclusion is that a Kratzer-style semantics remains the one to beat. With this assumption in place, we then ask how we should understand the relationship between true deontic modal statements and normative reasons. Should, for example, we hold that the truth of such a statement entails the existence of a normative reason for some agent to comply? Here we argue that, in many cases, acceptance of Kratzer’s semantics for deontic modals leaves open for substantive normative theorizing the question of whether an agent has a normative reason to comply with what she ought to do.

This paper introduces and argues for contrastivism about intentions. According to contrastivism, intention is not a binary relation between an agent and an action. Rather, it is a ternary relation between an agent, an action, and an alternative. Contrastivism is introduced via a discussion of cases of known but (apparently) unintended side effects. Such cases are puzzling. They put pressure on us to reject a number of highly compelling theses about intention, intentional action, and practical (...) reason. And they give rise to a puzzle about rather than constructions such as ‘I intend to φ rather than ψ’: In side effect cases it can seem wrong to claim that the subject intends to φ, yet acceptable to claim that they intend to φ rather than ψ. This cries out for explanation. Contrastivism provides a unified response to all of these problems. (shrink)

Given constructivism’s enduring popularity and appeal, it is perhaps something of a surprise that there remains considerable uncertainty among many philosophers about what constructivism is even supposed to be. My aim in this article is to make some progress on the question of how constructivism should be understood. I begin by saying something about what kind of theory constructivism is supposed to be. Next, I consider and reject both the standard proceduralist characterization of constructivism and also Sharon Street’s (...) ingenious standpoint characterization. I then suggest an alternative characterization according to which what is central is the role played by certain standards of correct reasoning. I conclude by saying something about the implications of this account for evaluating the success of constructivism. I suggest that certain challenges that have been raised against constructivist theories are based on dubious understandings of constructivism, whereas other challenges only properly come into focus once a proper understanding is achieved.

Contemporary forms of Kantian constitutivism generally begin with a conception of agency on which the constitutive aim of agency is some form of autonomy or self-unification. This chapter argues for a re-orientation of the Kantian constitutivist project towards views that begin with a conception of rationality on which both theoretical and practical rationality aim at forms of understanding. In a slogan, then, understanding-first as opposed to autonomy-first constitutivism. Such a view gives the constitutivist new resources for explaining many classes of (...) reasons, while also offering a new way of understanding the unity of theoretical and practical reason. The chapter concludes by arguing that the resulting view is best understood, not so much as an alternative to autonomy-first constitutivism, but as a complement to it. (shrink)

Less discussed than Hume’s skepticism about what grounds there could be for projecting empirical hypotheses is his concern with a skeptical regress that he thought threatened to extinguish any belief when we reflect that our reasoning is not perfect. The root of the problem is the fact that a reflection about our reasoning is itself a piece of reasoning. If each reflection is negative and undermining, does that not give us a diminution of our original belief to nothing? (...) It requires much attention to detail, we argue, to determine whether or not there is a skeptical problem in this neighborhood. Consider that if we subsequently doubt a doubt we had about our reasoning, that would suggest a restoration of some of the force of our original belief. We would then have instead of runaway skepticism an alternating sequence of pieces of skeptical reasoning that cancel each others’ effects on our justification in the original proposition, at least to some degree. We will argue that the outcome of the sequence of reflections Hume is imagining depends on information about a given case that is not known a priori. We conclude this from the fact that under three precise, explanatory, and viable contemporary reconstructions of what this kind of reasoning about reasoning could be like and how it has the potential to affect our original beliefs, a belief-extinguishing regress is not automatic or necessary.

This paper attempts to reconstruct Hume's argument in Treatise 1.4.1, 'Of Scepticism with Regard to Reason'.

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 paper champions the view (REG) that the concept of a normative reason for an agent S to perform an action A is that of an explanation why it would be good (in some way, to some degree) for S to do A. REG has numerous virtues, but faces some significant challenges which prompt many philosophers to be skeptical that it can correctly account for all our reasons. I demonstrate how five different puzzles about normative reasons can (...) be solved by attention to the concept of goodness, and in particular observing the ways in which it—and consequently, talk about reasons—is sensitive to context (ends and information). Rather than asking simply whether or not certain facts are reasons for S to do A, we need to explore the contexts in which it is and is not correct to describe a certain fact as “a reason” for S to do A. These five puzzles concern: (1) reasons for attitudes of the “right kind”, (2) evidence as reasons, (3) normative facts as reasons, (4) subjective reasons, and (5) attitudes as reasons. (shrink)

Are there are normative reasons to have – or refrain from having – certain emotions? The dominant view is that there are. I disagree. In this paper, I argue for Strong Eliminativism – the view that there are no reasons for emotions. My argument for this claim has two premises. The first premise is that there is a deliberative constraint on reasons: a reason for an agent to have an attitude must be able to feature in that (...) agent’s deliberation to that attitude. My argument for this premise is that in order to have reasons for an attitude, we need to be able to exhibit some relevant form of control over this attitude, and this relevant form of control is deliberative control. The second premise is that no one can deliberate to any emotion. My argument for this premise turns on the claim that there is no deliberative question that is settled by forming (or giving up) an emotion. I contend that this is so due to the well-known phenomenon of recalcitrant emotions: for any deliberative question that can be settled, there is no guarantee that the relevant emotional state will follow (or be revised). Strong Eliminativism follows from these two premises. (shrink)

Contrastivism about knowledge is the view that one does not just know some proposition. It is more adequate to say that one knows something rather than something else: I know that I am looking at a tree rather than a bush but I do not know that I am looking at a tree rather than a cleverly done tree imitation. Knowledge is a three-place relation between a subject, a proposition and a contrast set of propositions. There are several (...) advantages of a contrastivist view but also certain problems with it.

Epistemic contrastivism is the view that knowledge is a ternary relation between a person, a proposition and a set of contrast propositions. This view is in tension with widely shared accounts of practical reasoning: be it the claim that knowledge of the premises is necessary for acceptable practical reasoning based on them or sufficient for the acceptability of the use of the premises in practical reasoning, or be it the claim that there is a looser connection between knowledge and (...) practical reasoning. Given plausible assumptions, epistemic contrastivism implies that we should cut all links between knowledge and practical reasoning. However, the denial of any such link requires additional and independent arguments; if such arguments are lacking, then all the worse for epistemic contrastivism. (shrink)

Reasoning about mental states and processes is important in various subareas of the legal domain. A trial lawyer might need to reason and the beliefs, reasoning and other mental states and processes of members of a jury; a police officer might need to reason about the conjectured beliefs and reasoning of perpetrators; a judge may need to consider a defendant's mental states and processes for the purposes of sentencing and so on. Further, the mental states in question may (...) themselves be about the mental states and processes of other people. Therefore, if AI systems are to assist with reasoning tasks in law, they may need to be able to reason about mental states and processes. Such reasoning is riddled with uncertainty, and this is true in particular in the legal domain. The article discusses how various different types of uncertainty arise, and shows how they greatly complicate the task of reasoning about mental states and processes. The article concentrates on the special case of states of belief and processes of reasoning, and sketches an implemented, prototype computer program (ATT-Meta) that copes with the various types of uncertainty in reasoning about beliefs and reasoning. In particular, the article outlines the system's facilities for handling conflict between different lines of argument, especially when these lie within the reasoning of different people. The system's approach is illustrated by application to a real-life mugging example. [NB: The date on the archived preprint avail via this Phil* page has an incorrect date, 2011, on it.

In this essay, I consider an evolutionary debunking argument (EDA) that purports to undermine the epistemic justification of the belief in the reliability of our belief-forming processes, and an evolutionary vindicating argument (EVA) that seeks to establish that such a belief is epistemically justified. Whereas the EDA in question seems to fall prey to crippling self-defeat, the EVA under consideration seems to fall prey to vicious circularity. My interest in those arguments and the problems they face lies in what they (...) might tell us about the possibly aporetic nature of reason. For, if we take the EDA and the EVA in question to consist of true or plausible premises and valid inferences at which we arrive through a meticulous use of reason, then their falling victim to either crippling self-defeat or vicious circularity might be regarded as a sign that, when we push rational reflection on the reliability, or lack thereof, of our belief-forming capacities to the limit, we end up in a situation of aporia from which there seems to be no escape.

This paper offers a sketch of welfarist pluralism, a view that is intended to resolve a difficulty for non-derivative pluralists about normative reasons for belief. Welfarist pluralism is the view that all reasons for belief are rooted in wellbeing, and that wellbeing has as one of its components being in a positive epistemic state. The paper explores how this view can explain various pluralist intuitions and why it offers a plausible basis for combinatorial pluralists who believe that (...) alethic and pragmatic reasons for belief combine to determine what one ought to believe. The paper also considers the relationship between theoretical rationality and wellbeing, and provides a partial argument for the derivative normativity of at least some requirements of theoretical rationality.

This paper surveys some ways in which epistemic reasons ascriptions (or ERAs) appear to be context-sensitive, and outlines a framework for thinking about the nature of this context-sensitivity that is intimately related to ERAs' explanatory function.

This paper introduces constitutivism about practical reason, which is the view that we can justify certain normative claims by showing that agents become committed to these claims simply in virtue of acting. According to this view, action has a certain structural feature – a constitutive aim, principle, or standard – that both constitutes events as actions and generates a standard of assessment for action. We can use this standard of assessment to derive normative claims. In short, the authority of (...) certain normative claims arises from the bare fact that we are agents. This essay explains the constitutivst strategy, surveys the extant attempts to generate constitutivist theories, and considers the problems and prospects for the theory. (shrink)

Robert Koons claims that my previous critique of his “new” cosmological argument is vitiated by confusion about the nature of defeasible argumentation.In response, I claim that Koons misrepresents—and perhaps misunderstands—the nature of my objections to his “new” cosmological argument. The main claims which I defend are: (1) that the move from a non-defeasible to a defeasible causal principle makes absolutely no difference to the success of the cosmological argument in which it is contained; and (2) that, since it is (...) perfectly well understood that non-theists have many reasons for rejecting the defeasible causal principle, it is pointless to claim that the move to a defeasible principle brings about a shift in the “burden of proof”. (Since some people may have forgotten—or may choose to ignore—the fact that non-theists do have reasons for rejecting the defeasible causal principle, I also provide a discussion of a modest sample of these reasons.).

Copernican reasoning involves considering ourselves, in the absence of other information, to be randomly selected members of a reference class. Consider the reference class intelligent observers. If there are extraterrestrial intelligences (ETIs), taking ourselves to be randomly selected intelligent observers leads to the conclusion that it is likely the Earth has a larger population size than the typical planet inhabited by intelligent life, for the same reason that a randomly selected human is likely to come from a more populous country. (...) The astrophysicist Fergus Simpson contends that this reasoning supports the claims that the typical planet inhabited by ETIs is smaller than Earth (radius about 5,000km; cf. Earth's radius = 6,371km) and that the typical ETI is significantly larger than us about 314kg, the size of an adult male grizzly bear). Simpson's applications of Copernican reasoning are novel and exciting. They should be of interest to philosophers concerned with Richard Gott's delta t argument, the N=1 problem in astrobiology, limited principles of indifference, and probabilistic epistemology in general. While we agree with Simpson about the qualitative direction of his conclusions, we take issue with his presentation of precise quantitative results because his methods (1) display bias, (2) ignore other variables contributing to population size, (3) commit an equivocation, and (4) conceal their dependence on arbitrary assumptions.

There is a long tradition in formal epistemology and in the psychology of reasoning to investigate indicative conditionals. In psychology, the propositional calculus was taken for granted to be the normative standard of reference. Experimental tasks, evaluation of the participants’ responses and psychological model building, were inspired by the semantics of the material conditional. Recent empirical work on indicative conditionals focuses on uncertainty. Consequently, the normative standard of reference has changed. I argue why neither logic nor standard probability theory provide (...) appropriate rationality norms for uncertain conditionals. I advocate coherence based probability logic as an appropriate framework for investigating uncertain conditionals. Detailed proofs of the probabilistic non-informativeness of a paradox of the material conditional illustrate the approach from a formal point of view. I survey selected data on human reasoning about uncertain conditionals which additionally support the plausibility of the approach from an empirical point of view. (shrink)

This paper examines the view that desires are beliefs about normative reasons for action. It describes the view, and briefly sketches three arguments for it. But the focus of the paper is defending the view from objections. The paper argues that the view is consistent with the distinction between the direction of fit of beliefs and desires, that it is consistent with the existence of appetites such as hunger, that it can account for counterexamples that aim to show (...) that beliefs about reasons are not sufficient for desire, such as weakness of will, and that it can account for counterexamples that aim to show that beliefs about reasons are not necessary for desire, such as addiction. The paper also shows how it is superior to the view that desires are appearances of the good. (shrink)

Enkratic reasoning—reasoning from believing that you ought to do something to an intention to do that thing—seems good. But there is a puzzle about how it could be. Good reasoning preserves correctness, other things equal. But enkratic reasoning does not preserve correctness. This is because what you ought to do depends on your epistemic position, but what it is correct to intend does not. In this paper, I motivate these claims and thus show that there is a puzzle. I (...) then argue that the best solution is to deny that correctness is always independent of your epistemic position. As I explain, a notable upshot is that a central epistemic norm directs us to believe, not simply what is true, but what we are in a position to know. (shrink)

In this commentary paper, we are taking one step further in questioning the central assumptions in the bioethical debates about reproductive technologies. We argue that the very distinction between “person affecting” and “identity affecting” interventions is based on a questionable form of material-origin essentialism. Questioning of this form of essentialist approach to human identity allows treating genome editing and genetic selection as more similar than they are taken to be in the standard approaches. It would also challenge the idea (...) that normative reasons we have in these two types of cases markedly differ in strength. (shrink)

In recent years, semiotics has become an innovative theoretical framework in mathematics education. The purpose of this article is to show that semiotics can be used to explain learning as a process of experimenting with and communicating about one's own representations of mathematical problems. As a paradigmatic example, we apply a Peircean semiotic framework to answer the question of how students learned the concept of "distribution" in a statistics course by "diagrammatic reasoning" and by developing "hypostatic abstractions," that is (...) by forming new mathematical objects which can be used as means for communication and further reasoning. Peirce's semiotic terminology is used as an alternative for notions such as modeling, symbolizing, and reification. We will show that it is a precise instrument of analysis with regard to the complexity of learning and of communication in mathematics classroom. (shrink)

Research on preference reversals has demonstrated a disproportionate influence of outcome probability on choices between monetary gambles. The aim was to investigate the hypothesis that this is a prominence effect originally demonstrated for riskless choice. Another aim was to test the structure compatibility hypothesis as an explanation of the effect. The hypothesis implies that probability should be the prominent attribute when compared with value attributes both in a choice and a preference rating procedure. In Experiment 1, two groups of undergraduates (...) were presented with medical treatments described by two value attributes (effectiveness and pain-relief). All participants performed both a matching task and made preference ratings. In the latter task, outcome probabilities were added to the descriptions of the medical treatments for one of the groups. In line with the hypothesis, this reduced the prominence effect on the preference ratings observed for effectiveness. In Experiment 2, a matching task was used to demonstrate that probability was considered more important by a group of participating undergraduates than the value attributes. Furthermore, in both choices and preference ratings the expected prominence effect was found for probability. (shrink)

In 1984 the author published From Knowledge to Wisdom, a book that argued that a revolution in academia is urgently needed, so that problems of living, including global problems, are put at the heart of the enterprise, and the basic aim becomes to seek and promote wisdom, and not just acquire knowledge. Every discipline and aspect of academia needs to change, and the whole way in which academia is related to the rest of the social world. Universities devoted to the (...) pursuit of knowledge and technological know-how betray reason and, as a result, betray humanity. As a result of becoming more intellectually rigorous, academic inquiry becomes of far greater benefit to humanity. If the revolution argued for all those years ago had been taken up and put into academic practice, we might now live in a much more hopeful world than the one that confronts us. Humanity might have begun to learn how to solve global problems; the Amazon rain forests might not face destruction; we might not be faced with mass extinction of species; Brexit might not have been voted for in the UK in 2016, and Trump might not have been elected President in the USA. An account is given of work published by the author during the years 1972 to 2021 that expounds and develops the argument. The conclusion is that we urgently need to create a high-profile campaign devoted to transforming universities in the way required so that humanity may learn how to make social progress towards a better, wiser, more civilized, enlightened world.

Causal reasoning and game-theoretic reasoning are fundamental topics in artificial intelligence, among many other disciplines: this paper is concerned with their intersection. Despite their importance, a formal framework that supports both these forms of reasoning has, until now, been lacking. We offer a solution in the form of (structural) causal games, which can be seen as extending Pearl's causal hierarchy to the game-theoretic domain, or as extending Koller and Milch's multi-agent influence diagrams to the causal domain. We then consider three (...) key questions: i) How can the (causal) dependencies in games - either between variables, or between strategies - be modelled in a uniform, principled manner? ii) How may causal queries be computed in causal games, and what assumptions does this require? iii) How do causal games compare to existing formalisms? To address question i), we introduce mechanised games, which encode dependencies between agents' decision rules and the distributions governing the game. In response to question ii), we present definitions of predictions, interventions, and counterfactuals, and discuss the assumptions required for each. Regarding question iii), we describe correspondences between causal games and other formalisms, and explain how causal games can be used to answer queries that other causal or game-theoretic models do not support. Finally, we highlight possible applications of causal games, aided by an extensive open-source Python library. (shrink)

The species problem is often described as the abundance of conflicting definitions of _species_, such as the biological species concept and phylogenetic species concepts. But biologists understand the notion of species in a non-definitional as well as a definitional way. In this article I argue that when they understand _species_ without a definition in their mind, their understanding is often mediated by the notion of _good species_, or prototypical species, as the idea of ``prototype'' is explicated in cognitive psychology. This (...) distinction helps us make sense of several puzzling phenomena regarding biologists' dealing with species, such as the fact that in everyday research biologists often behave as if the species problem is solved, while they should be fully aware that it is not. I also briefly discuss implications of this finding, including that some extant attempts to answer what the nature of species is have an inadequate assumption about how the notion of species is represented in biologists' minds.

Just like Rudolf Carnap, but in a slightly different composition, I divide language into three types of conceptual means: classification, specifically scientific and specifically general comparative concepts of different types. I associate classification concepts with the ability to reason on any topic, that is, with reasonable thinking. Concrete scientific comparative concepts determine the comprehension of natural and social processes, their objective cognition in the form of rational thinking (reason), while concrete universal comparative concepts define philosophy (wisdom), understood as knowledge of (...) the universal. Based on three types of thinking (prudence, reason, wisdom) in 2010 at a symposium in Greece, I presented the ideas of morality in the context of human development in the form of a proposed article.

Epistemological contrastivism can model how infallible knowledge functions by employing the explanatory resource of structural differences between contrastive propositions, e.g., “P rather than Q”, and orthodox propositions, e.g., “P”. In doing so we notice that how this difference factors into our conception of infallible knowledge depends on two aspects: one, whether belief acts as a necessary condition for knowledge, and two, whether epistemic justification is construed as consciously internalist or non-consciously externalist. We further leverage the notion of phenomenal resolution, (...) conceived as an outcome of one’s discriminative capacities in accessing their evidence, to clarify in what sense it becomes reasonable to say that the truth of P mutually excludes the truth of Q when the latter is contrasted to the former. Importantly then, there is a way of infallibly knowing that P that is indistinguishable from infallibly knowing that P rather than Q, and a way that is not. (shrink)

This paper takes a closer look at ordinary thought and talk about motivating reasons, in an effort to better understand how it works. This is an important first step in understanding whether—and if so, how—such thought and talk should inform or constrain our substantive theorizing. One of the upshots is that ordinary judgments about motivating reasons are at best a partial and defeasible guide to what really matters, and that so-called factualists, propositionalists, and statists are all (...) partly right, as well as partly wrong, when it comes to the question of what motivating reasons “are”.

In this paper we propose a new semantics, based on the notion of a "contextual model", that makes it possible to express and compare — within a unique formal framework — different views on the roles of various notions of context in knowledge ascriptions. We use it to provide a logical analysis of such positions as skeptical and moderate invariantism, contextualism, and subject-sensitive invariantism. A dynamic formalism is also proposed that offers new insights into a classical skeptical puzzle.

We asked college students to make judgments about realistic moral situations presented as dilemmas (which asked for an either/or decision) vs. problems (which did not ask for such a decision) as well as when the situation explicitly included affectively salient language vs. non-affectively salient language. We report two main findings. The first is that there are four different types of cognitive strategy that subjects use in their responses: simple reasoning, intuitive judging, cautious reasoning, and empathic reasoning. We give operational (...) definitions of these types in terms of our observed data. In addition, the four types characterized strategies not only in the whole sample, but also in all of the subsamples in our study. The second finding is that the intuitive judging type comprised approximately 26% of our respondents, while about 74% of our respondents employed one of the three styles of reasoning named above. We think that these findings present an interesting challenge to models of moral cognition which predict that there is either a single, or a single most common, strategy – especially a strategy of relying upon one’s intuitions – that people use to think about moral situations.

We can contrast rationalising explanations of the form S φs because p with those of the form S φs because S believes that p. According the Common Kind View, the two sorts of explanation are the same. The Disjunctive View denies this. This paper sets out to elucidate the sense in which the Common Kind Theorist asserts, but the Disjunctivist denies, that the two explanations are the same. I suggest that, in the light of the distinction between kinds of explanation (...) and particular explanations, the relevant sameness thesis is ambiguous, thus giving us two distinct versions of the Common Kind View. I then argue that the only direct arguments for Disjunctivism available in the literature fail because they only succeed in undermining one version of the Common Kind View. I finish, however, by providing a fresh argument for the Disjunctive View which aims to undermine both versions of its competitor. (shrink)

This is a revised and extended version of the formal theory of holes outlined in the Appendix to the book "Holes and Other Superficialities". The first part summarizes the basic framework (ontology, mereology, topology, morphology). The second part emphasizes its relevance to spatial reasoning and to the semantics of spatial prepositions in natural language. In particular, I discuss the semantics of ‘in’ and provide an account of such fallacious arguments as “There is a hole in the sheet. The sheet is (...) in the drawer. Ergo *there is a hole in the drawer”. (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)

This essay responds to the thoughtful essays on the Order of Public Reason (OPR) by Elvio Baccarini, Giulia Bistagnino and Nenad Miscevic. All three essays interrogate OPR’s understanding of moral theory - “meta” matters about the nature of morality, reasons and modeling within moral theories. I first turn to the general understanding of the moral enterprise underlying OPR, explaining why it takes a view at odds with the contemporary mainstream in moral philosophy. I then explain the idea of (...) moral truth in OPR: when it comes to social morality, moral truth is necessarily a function of what can be endorsed by some collectivity. Th is leads to a fundamental worry about theories of public reason: why is the endorsement of the public so important? And if some sort of public endorsement is really so terribly important, how can a theory of public reason withstand the fact that it advances its own controversial claims that cannot be publicly endorsed? After considering when public endorsement is necessary, and when public reason theories can make controversial claims, I close by considering in what way OPR does, and in what way it does not, employ a thought experiment, and the complexities of that.

Four experiments examined children's ability to reason about the causal significance of the order in which 2 events occurred (the pressing of buttons on a mechanically operated box). In Study 1, 4-year-olds were unable to make the relevant inferences, whereas 5-year-olds were successful on one version of the task. In Study 2, 3-year-olds were successful on a simplified version of the task in which they were able to observe the events although not their consequences. Study 3 found that older (...) children had difficulties with the original task even when provided with cues to attend to order information. However, 5-year-olds performed successfully in Study 4, in which the causally relevant event was made more salient. (shrink)

Are non-natural properties worth caring about? I consider two objections to metaethical non-naturalism. According to the intelligibility objection, it would be positively unintelligible to care about non-natural properties that float free from the causal fabric of the cosmos. According to the ethical idlers objection, there is no compelling motivation to posit non-natural normative properties because the natural properties suffice to provide us with reasons. In both cases, I argue, the objection stems from misunderstanding the role that non-natural (...) properties play in the non-naturalist's understanding of normativity. The role of non-natural properties is not to be responded to, but to "mark" which natural properties it is correct for us to respond to in certain ways. (shrink)

In this short comment on Just, Reasonable Multiculturalism, I concentrate on the permissible extent of interference by a liberal state in a community within that state when such interference aims to protect individuals within that community from it. He and I both value individuals and want them protected, of course. This shared value, however, leads us to different conclusions. On any liberal view, individuals must be allowed to act as they wish subject only to specific sorts of justified limitations. In (...) the mainstream approach that Cohen-Almagor accepts, these will include limitations necessary to not merely protect but also to promote autonomy. On my own view, by contrast, it is protection alone that justifies interference. I thus spell out Cohen-Almagor’s view about the need for interference with non-liberal groups within a liberal state and indicate my disagreement. (shrink)

Mengzi 孟子 6A2 contains the famous water analogy for the innate goodness of human nature. Some evaluate Mengzi’s reasoning as strong and sophisticated; others, as weak or sophistical. I urge for more nuance in our evaluation. Mengzi’s reasoning fares poorly when judged by contemporary standards of analogical strength. However, if we evaluate the analogy as an instance of correlative thinking within a yin-yang 陰陽 cosmology, his reasoning fares well. That cosmology provides good reason to assert that water tends to flow (...) downward, not because of available empirical evidence, but because water correlates to yin and yin correlates to naturally downward motion. Substantiating these contentions also gives occasion to better understand the nature of correlative reasoning in classical Chinese philosophy. (shrink)

I argue that generic generalizations expressed in language (i.e. ‘generics’) are apt for clinical reasoning. I introduce generics and describe two problems in the use and interpretation of generics: Generics may license inaccurate judgements about the frequency of events or properties within a group (i.e. a problem with the ‘truth-aptness’ of generics) and may facilitate problematic beliefs about social kinds (e.g. prejudice or essentializing). I provide an account of clinical reasoning and describe some features of what I call (...) ‘good’ clinical reasoning. I offer examples of generics in clinical contexts and examine how the two problems with generics (i.e. of truth-aptness and social generics) can harm patients and impair clinical reasoning. However, I ultimately argue that generics are important for good clinical reasoning because they track ‘conspicuous’ features of disease processes (e.g. severe possible outcomes). Further, I argue that prejudicial generics are often irrational to believe. Social generics that are rational to believe need not lead to problematic implicatures about social kinds and can instead facilitate meaningfully articulating societal injustices. I then argue that statistical statements, which are tempting alternatives to generics in clinical reasoning, are no better than generics for good clinical reasoning. (shrink)

There are two competing theoretical frameworks with which cognitive sciences examines how people reason. These frameworks are broadly categorized into logic and probability. This paper reports two applied experiments to test which framework explains better how people reason about evidence in criminal cases. Logical frameworks predict that people derive conclusions from the presented evidence to endorse an absolute value of certainty such as ‘guilty’ or ‘not guilty’ (e.g., Johnson-Laird, 1999). But probabilistic frameworks predict that people derive conclusions from the (...) presented evidence in order that they may use knowledge of prior instances to endorse a conclusion of guilt which varies in certainty (e.g., Tenenbaum, Griffiths, & Kemp, 2006). Experiment 1 showed that reasoning about evidence of prior instances, such as disclosed prior convictions, affected participants’ underlying ratings of guilt. Participants’ guilt ratings increased in certainty according to the number of disclosed prior convictions. Experiment 2 showed that participants’ reasoning about evidence of prior convictions and some forensic evidence tended to lead participants to endorse biased ‘guilty’ verdicts when rationally the evidence does not prove guilt. Both results are predicted by probabilistic frameworks. The paper considers the implications for logical and probabilistic frameworks for reasoning in the real world. (shrink)

Bernard Williams's motivational reasons-internalism fails to capture our first-order reasons judgements, while Derek Parfit's nonnaturalistic reasons-externalism cannot explain the nature or normative authority of reasons. This paper offers an intermediary view, reformulating scepticism about external reasons as the claim not that they don't exist but rather that they don't matter. The end-relational theory of normative reasons is proposed, according to which a reason for an action is a fact that explains why the action (...) would be good relative to some end, where the relevant end for any ascription of reasons is determined by the speaker's conversational context. Because these ends need not be the agent's ends, Williams is wrong to reject the existence of external reasons. But contra Parfit, a reason for action is only important for an agent if it is motivationally internal to that agent. (shrink)

Over the last 30 years the Indian philosopher-economist Amartya Sen has developed an original normative approach to the evaluation of individual and social well-being. The foundational concern of this ‘capability approach’ is the real freedom of individuals to achieve the kind of lives they have reason to value. This freedom is analysed in terms of an individual’s ‘capability’ to achieve combinations of such intrinsically valuable ‘beings and doings’ (‘functionings’) as being sufficiently nourished and freely expressing one’s political views. In this (...) account, ‘development’ is conceived as the expansion of individuals’ capability, and thus as a concept that goes beyond the economic growth of third world countries. My thesis is a philosophical examination of Sen’s capability approach. In the first part (chapters 1-3) I present and defend my interpretation of Sen’s work. (shrink)

What is it to have a reason? According to one common idea, the "Factoring Account", you have a reason to do A when there is a reason for you to do A which you have--which is somehow in your possession or grasp. In this paper, I argue that this common idea is false. But though my arguments are based on the practical case, the implications of this are likely to be greatest in epistemology: for the pitfalls we fall into when (...) trying to defend the Factoring Account reflect very well the major developments in empiricist epistemology during the 20th century. I conjecture that this is because epistemologists have been--wrongly--wedded to the Factoring Account about evidence, which I conjecture is a certain kind of reason to believe. (shrink)
