In this paper I articulate and defend a view that I call phenomenal dogmatism about intuitive justification. It is dogmatic because it includes the thesis: if it intuitively seems to you that p, then you thereby have some prima facie justification for believing that p. It is phenomenalist because it includes the thesis: intuitions justify us in believing their contents in virtue of their phenomenology—and in particular their presentational phenomenology. I explore the nature of presentational phenomenology as it (...) occurs perception, and I make a case for thinking that it is present in a wide variety of logical, mathematical, and philosophical intuitions.

I argue for three central theses: ‘intuition’ is ambiguous, in material object metaphysics ‘intuition’ refers to pre-theoretical beliefs, and these pre-theoretical beliefs are generated by an innate physical reasoning system. I begin by outlining the relevant background discussions on the nature of intuitions and their role in philosophy to motivate the need for a more careful investigation of the meaning of ‘intuition’ and the role of intuitions in specific sub-disciplines of philosophy. In chapters one and two I (...) argue that ‘intuition’ is ambiguous between an inflationary and deflationary sense. In the inflationary sense, ‘intuition’ refers to a priori intellectual seemings with a special phenomenology, conceptual etiology, and modal content. In the deflationary sense, ‘intuition’ refers to beliefs or inclinations to believe. In chapter three I specifically examine the use of intuitions in material object metaphysics and conclude that in this sub-community ‘intuition’ is used in the deflationary sense to refer to pre-theoretical beliefs. Drawing from research on infant cognition, in the final chapter I argue that intuitions regarding material object metaphysics are those judgments that arise from an innate physical reasoning system. Based on this empirical observation, I argue that metaphysicians ought to give preference to abstract intuitions over intuitions regarding concrete cases because these abstract intuitions reflect the innate structure of our physical reasoning mechanisms.

In the first part of this paper I will characterize the specific nature of rational intuition. It will be claimed that rational intuition is an evidential state with modal content that has an a priori source. This claim will be defended against several objections. The second part of the paper deals with the so-called explanationist objection against rational intuition as a justifying source. According to the best reading of this objection, intuition cannot justify any judgment since there is no (...) metaphysical explanation of its reliability. It will be argued that in the case of intuition the very demand of such an explanation is based on a category mistake. (shrink)

The article is devoted to the nature of the topological intuition and disclosure of the specifics of topological heuristics in the framework of philosophical theory of knowledge. As we know, intuition is a one of the support categories of the theory of knowledge, the driving force of scientific research. Great importance is mathematical intuition for the solution of non-standard problems, for which there is no algorithm for such a solution. In such cases, the mathematician addresses the so-called heuristics, built (...) on the basis of guesswork, obtained by intuition. The author substantiates the conclusion that topological intuition significantly specific compared to a traditional mathematical intuitions of Euclidean geometry. Today topology is a rapidly developing field of modern mathematics, integrates nicely with other sections of mathematical science. In its most general form of the topology can be defined as the branch of mathematics that studies the properties of spatial figures, does not change under deformations. The topological intuition is an instrument for development of topology on the basis of typological heuristics, which is the result of applying topological intuition to the objects topology. The author demonstrates in detail providing with the examples the specificity of topological heuristics and establishes its interconnection with Euclidean geometry. The author draws the conclusion about the fundamentality of topological intuition, and that it, perhaps, is primary in relation to traditionally understood mathematical intuition. (shrink)

Psychological evidence suggests that laypeople understand the world around them in terms of intuitive ontologies which describe broad categories of objects in the world, such as ‘person’, ‘artefact’ and ‘animal’. However, because intuitive ontologies are the result of natural selection, they only need to be adaptive; this does not guarantee that the knowledge they provide is a genuine reflection of causal mechanisms in the world. As a result, science has parted ways with intuitive ontologies. Nevertheless, since the brain is evolved (...) to understand objects in the world according to these categories, we can expect that they continue to play a role in scientific understanding. Taking the case of human evolution, we explore relationships between intuitive ontological and scientific understanding. We show that intuitive ontologies not only shape intuitions on human evolution, but also guide the direction and topics of interest in its research programmes. Elucidating the relationships between intuitive ontologies and science may help us gain a clearer insight into scientific understanding. (shrink)

In this paper, I focus on the concept of intuition in Schelling’s philosophy. More specifically, I show how Schelling attributes to intuition an ontological value by essentially relating it to freedom and primal Being. Indeed, for Schelling intuition is both the main instrument of philosophy and the highest product of freedom, by which we attain the so-called “God’s-eye point of view” and concretely grasp things in their immediate existence. That is, through intuition it is possible to grasp the absolute and (...) original unity of the principles, namely of being and thought, subject and object and freedom and necessity. Accordingly, I argue that Schelling’s conception of intuition, rather being a merely theoretical speculation, is aimed at demonstrating the immanent nature of Being, which is one of the key points in Schelling’s philosophy.

According to Kant, the axioms of intuition, i.e. space and time, must provide an organization of the sensory experience. However, this first orderliness of empirical sensations seems to depend on a kind of faculty pertaining to subjectivity, rather than to the encounter of these same intuitions with the real properties of phenomena. Starting from an analysis of some very significant developments in mathematical and theoretical physics in the last decades, in which intuition played an important role, we argue that (...) nevertheless intuition comes into play in a fundamentally different way to that which Kant had foreseen: in the form of a formal or “categorical” yet not sensible intuition. We show further that the statement that our space is mathematically three-dimensional and locally Euclidean by no means follows from a supposed a priori nature of the sensible or subjective space as Kant claimed. In fact, the three-dimensional space can bear many different geometrical and topological structures, as particularly the mathematical results of Milnor, Smale, Thurston and Donaldson demonstrated. On the other hand, it has been stressed that even the phenomenological or perceptual space, and especially the visual system, carries a very rich geometrical organization whose structure is essentially non-Euclidean. Finally, we argue that in order to grasp the meaning of abstract geometric objects, as n-dimensional spaces, connections on a manifold, fiber spaces, module spaces, knotted spaces and so forth, where sensible intuition is essentially lacking and where therefore another type of mathematical idealization intervenes, we need to develop a new form of intuition.

This thesis explores the role and nature of intuition in philosophical inquiry. Appeals to intuition have either been used as evidence for or against philosophical theories or as constitutive features of judgement. I attempt to understand our uses of intuition by appealing to tacit knowledge. The hope is to elicit a picture of intuition as being practical and explanatory. Our reliance on intuition is warranted if we understand it as an expression of tacit knowledge.

The four experiments presented support Boyer's theory that counterintuitive concepts have transmission advantages that account for the commonness and ease of communicating many non-natural cultural concepts. In Experiment 1, 48 American college students recalled expectation-violating items from culturally unfamiliar folk stories better than more mundane items in the stories. In Experiment 2, 52 American college students in a modified serial reproduction task transmitted expectation-violating items in a written narrative more successfully than bizarre or common items. In Experiments 3 and 4, (...) these findings were replicated with orally presented and transmitted stimuli, and found to persist even after three months. To sum, concepts with single expectation-violating features were more successfully transmitted than concepts that were entirely congruent with category-level expectations, even if they were highly unusual or bizarre. This transmission advantage for counterintuitive concepts may explain, in part, why such concepts are so prevalent across cultures and so readily spread. (shrink)

A natural way to think about epistemic possibility is as follows. When it is epistemically possible (for a subject) that p, there is an epistemically possible scenario (for that subject) in which p. The epistemic scenarios together constitute epistemic space. It is surprisingly difficult to make the intuitive picture precise. What sort of possibilities are we dealing with here? In particular, what is a scenario? And what is the relationship between scenarios and items of knowledge and belief? This chapter tries (...) to make sense of epistemic space. It explores different ways of making sense of scenarios and of their relationship to thought and language. It discusses some issues that arise and outlines some applications to the analysis of the content of thought and the meaning of language. (shrink)

Scientific interest in religion often focusses on the “puzzle of belief”: how people develop and maintain religious beliefs despite a lack of evidence and the significant costs that those beliefs incur. A number of researchers have suggested that humans are predisposed towards supernatural thinking, with innate cognitive biases engendering, for example, the misattribution of intentional agency. Indeed, a number of studies have shown that nonbelievers often act “as if” they believe. For example, atheists are reluctant to sell the very souls (...) they deny having, or to angrily provoke the God they explicitly state does not exist. In our own recent work, participants who claimed not to believe in the afterlife nevertheless demonstrated a physiological fear response when informed that there was a ghost in the room. Such findings are often interpreted as evidence for an “implicit” belief in the supernatural that operates alongside (and even in contradiction to) an individual’s conscious (“explicit”) religious belief. In this article, we investigate these arguably tenuous constructs more deeply and suggest some possible empirical directions for further disentangling implicit and explicit reasoning. (shrink)

Descriptions of how managers think about the moral questions that come up in their work lives are analyzed to draw out the moral assumptions to which they commonly refer. The moral standards thus derived are identified as (1) honesty in communication, (2) fair treatment, (3) special consideration, (4) fair competition, (5) organizational responsibility, (6) corporate social responsibility, and, (7) respect for law. It is observed that these normative standards assume the cultural form of social conventions but because managers invoke them (...) as largely private intuitions, their cultural status remains precarious and unclear. This is the second in a research series of three papers. (shrink)

Explaining intuitions in terms of "facts of our natural history" is compatible with rationally trusting them. This compatibilist view is defended in the present paper, focusing upon nomic and essentialist modal intuitions. The opposite, incompatibilist view alleges the following: If basic modal intuitions are due to our cognitive make-up or "imaginative habits" then the epistemologists are left with a mere non-rational feeling of compulsion on the side of the thinker. Intuitions then cannot inform us about modal (...) reality. In contrast, the paper argues that there are several independent sources of justification which make the feeling of compulsion rational: the prima-facie and a priori ones come from the obviousness of our basic modal intuitions and our not being able to imagine things otherwise, others, a posteriori, from the epistemic success of these intuitions. Further, the general scheme of evolutionary learning is reliable, reliability is preserved in the resulting individual's cognitive make-up, and we can come to know this a posteriori. The a posteriori appeal to evolution thus plays a subsidiary role in justification, filling the remaining gap and removing the residual doubt. Explaining modal intuitions is compatible with moderate realism about modality itself. (shrink)

A central issue in debates about Kant and nonconceptualism concerns the nature of intuition. There is sharp disagreement among Kant scholars about both whether, prior to conceptualization, mere intuition can be considered conscious and, if so, how determinate this consciousness is. In this article, I argue that Kant regards pre-synthesized intuition as conscious but indeterminate. To make this case, I contextualize Kant's position through the work of H.S. Reimarus, a predecessor of Kant who influenced his views on animals, infants, (...) and the role of attention. I use Reimarus to clarify Kant's otherwise ambiguous commitments on the determinacy of intuition in animals and newborns, and the role attention, concepts, and judgment play in making intuited contents determinate. This contextualization helps to shed light on Kant's discussion of pre-synthesized intuition in the threefold synthesis of the A-Deduction by demonstrating that Kant's theory of mind in the deduction offers transcendental grounding for empirical accounts of infant development like Kant and Reimarus's. The upshot is a Kant at odds with many recent interpretations of his theory of mind: pre-synthesized intuition is conscious but indeterminate. (shrink)

In this paper I provide a new account of linguistic presuppositions, on which they are ancillary speech acts defined by constitutive norms. After providing an initial intuitive characterization of the phenomenon, I present a normative speech act account of presupposition in parallel with Williamson’s analogous account of assertion. I explain how it deals well with the problem of informative presuppositions, and how it relates to accounts for the Triggering and Projection Problems for presuppositions. I conclude with a brief discussion of (...) the consequences of the proposal for the adequacy of Williamson’s account of assertion. (shrink)

This dissertation examines the recent arguments against the “Centrality” thesis—the thesis that intuition plays central evidential roles in philosophical inquiry—and their implications for the negative program in experimental philosophy. Two types of objections to Centrality are discussed. First, there are some objections which turn out to only work against Centrality when it is taken as a potential form of philosophical exceptionalism. I respond by showing that negative experimental philosophy doesn’t need the assumption that philosophy is distinctive in its reliance on (...) intuitions. Second, there are some objections which turn out to be related to some particular view concerning the nature of evidence. In response, I distinguish between several different versions of Centrality, and argue that the version of Centrality that experimentalists need remains innocuous. Though none of the arguments against Centrality works as intended, I agree with its opponents that negative experimental philosophers have mischaracterized philosophical practice in a way which has problematic consequences for at least some versions of their argument. Specifically, I contend that philosophical practice grants important evidential status to general intuitions and context-rich intuitions, but extant experimental studies have almost exclusively focused on case intuitions and context-poor intuitions. I conclude that those who work on the negative program of experimental philosophy need to more carefully examine how philosophers actually use intuition in their practice. (shrink)

We readily claim that great moral catastrophes such as the Holocaust involve evil in some way, although it' not clear what this amounts to in a secular context. This paper seeks to provide a secular account of what evil is. It examines what is intuitively the most plausible account, namely that the evil act involves the production of great suffering (or other disvalue), and argues that such outcomes are neither necessary nor sufficient for an act to be evil. Only an (...) appeal to distinctive patterns of motivation, so it is argued, will allow us to accommodate our intuitionsabout which acts are evil, and hence will provide an adequate account of the nature of evil.

The redemption thesis assumes that how events in a person’s life are related to one another is important in evaluating the person’s welfare throughout life. In particular, according to this thesis of welfare, the fact that a person’s previous hardships contribute to bringing out the same person’s later successes, and the person would regard the hardships as having been worthwhile in light of the successes makes the person’s life better for the person herself. Recently, Ian D. Dunkle provided four objections (...) to the redemption thesis: the intuition concern, the different redemptions argument, the downplaying hardships argument, and the reconciled irreconcilables argument. This paper examines these four objections. In particular, this paper dismisses all the objections showing that the redemption thesis bases on an appealing idea, does not consider the degree of hardship significant in itself, has plausible reasons to evaluate hardships not as serious as people think, and can successfully reconcile its synchronic and diachronic evaluations.

Kant is the last classical practitioner of foundationalist epistemology in the Cartesian tradition, a tradition which saw the major problem of the theory of knowledge as one of providing a metaphysical account of the way in which the subjective contents of the individual mind come to have indubitable objective reference. But he is also the inaugurator of a very different approach to epistemology, one that sees methodology or rules of cognitive procedure as fundamental in determining the objectivity of knowledge. An (...) examination of Kant's reconstruction of the traditional form-matter distinction and his application of it to the manifold of intuition in the Critique of Pure Reason brings out the transitional character of his philosophy with particular force, and shows the immense impact of his work on the central epistemological issues of representation, explanation, and justification. While Kant continues to employ the traditional term Vorstellung , he extends its signification beyond that of a subjective mental content to an intersubjectively shared scheme of description. Where he adopts scholastic usage in referring to categories as concepts, he does not regard them as highest genera, but interprets them as rules of connection, thereby providing a logical framework suitable for functional, rather than essentialist explanation. Finally, while retaining in his transcendental psychology the conception of mental activity derivative of the older empirical psychology, Kant still manages to distinguish successfully the previously conflated questions of the causal origins vs. the grounds of justification of knowledge. Consideration of subsequent developments in regard to these issues in the light of Kant's work not only lends a certain amount of support to pragmatic conceptions of the nature of knowledge and its justification, but also suggests some promising directions for future epistemological investigation along evolutionary lines.

The way in which mathematics relates to experience has deeply engaged philosophers from the scientific revolution to the present. It has strongly influenced their views on epistemology, mathematics, science, and the nature of reality. Kant's views on the nature of mathematics and its relation to experience both influence and are influenced by his epistemology, and in particular the distinction Kant draws between concepts and intuitions. My dissertation contributes to clarifying the role of intuition in Kant's theory of (...) mathematical cognition. It focuses in particular on Kant's theory of magnitudes. This theory explains the applicability of mathematics to experience while bridging his philosophy of mathematics and his philosophy of science; it is therefore central. Kant's views on magnitudes, however, have been neglected. ;The dissertation divides into four parts. It begins by analyzing Kant's concept of magnitude and the closely related concepts of quanta, quantitas, quantity and number. These clarifications lay the groundwork for reconstructing and evaluating Kant's views. ;Understanding Kant's theory of mathematical cognition requires understanding how the quantitative forms of judgment and the categories of quantity are employed in mathematics. I argue for an interpretation that reflects the influence of 18$\sp{\rm th}$ Century metaphysics on Kant's thought, and reveals Kant's attempt to find a place for a mathematical conception of the world within that metaphysics. ;I also examine Kant's arguments for two fundamental properties of space--infinite divisibility and unlimited extent. I argue that intuition plays a perceptual role that can only be understood within the context of Kant's theory of imagination. ;Finally, I argue that according to Kant, a homogeneous manifold in intuition is required to represent composition and a mathematical version of the part/whole relation. The dissertation uses a modern understanding of the properties of relations to analyze the part/whole relations Kant refers to in his logic, and contrast them with the part/whole relations in his theory of magnitudes. Modern measurement theory aids in identifying Kant's insights into the conditions for the applicability of mathematics to experience. Kant's insights constitute an important part of his views on the role of intuition in mathematics. (shrink)

Standard methods in experimental philosophy have sought to measure folk intuitions using experiments, but certain limitations are inherent in experimental methods. Accordingly, we have designed the Free-Will Intuitions Scale to empirically measure folk intuitions relevant to free-will debates using a different method. This method reveals what folk intuitions are like prior to participants' being put in forced-choice experiments. Our results suggest that a central debate in the experimental philosophy of free will—the “natural” compatibilism debate—is mistaken in (...) assuming that folk intuitions are exclusively either compatibilist or incompatibilist. They also identify a number of important new issues in the empirical study of free-will intuitions. (shrink)

The paper studies the nature of understanding in condensed matter physics (CMP), mediated by the successful employment of its models. I first consider two obvious candidates for the criteria of model-based understanding, Van Fraassen's sense of empirical adequacy and Hacking's instrumental utility , and conclude that both are unsatisfactory. Inspired by Hasok Chang's recent proposal to reformulate realism as the pursuit of ontological plausibility in our system of knowledge, we may require the model under consideration to be understood (or (...) intelligible) before claiming model-based understanding. Here the understanding of a model typically consists of the following: figuring out at least one plausible (preferably realistic) physical mechanism for the model, determining the theoretical consequences of the model by mathematically probing it and developing our physical intuitions about the model. I consider the q-state Potts model to illustrate. After having understood a model, we may employ the model to understand its target phenomena in the world. This is done by matching one of the interpretative models of the model with the central features of the phenomena. The matching should be motivated (ideally both theoretically and empirically) in the sense that we have good reason to believe that the central features of the phenomena can be thought of as having more or less the same structure as postulated by the interpretative model. In conclusion, I propose a two-stage account of model-based understanding in CMP: (1) understanding of a model and (2) matching a target phenomenon with a well-motivated interpretative model of the model. Empirical success and instrumental utility both play their roles in the evaluation of how successful the model is, but are not the essential part of model-based understanding. (shrink)

In "General Information in Relevant Logic" (Synthese 167, 2009), the semantics for relevant logic is interpreted in terms of objective information. Objective information is potential data that is available in an environment. This paper explores the notion of objective information further. The concept of availability in an environment is developed and used as a foundation for the semantics, in particular, as a basis for the understanding of the information that is expressed by relevant implication. It is also used to understand (...) the nature of misinformation. A form of relevant logic—called "LOI" for "logic of objective information"—is presented and the relationship between the justification of its proof theory and the semantics is discussed. This relationship is rather reciprocal. Intuitive features of the logic are used to interpret and justify aspects of the model theory and intuitive aspects of the model theory are used to interpret and justify features of the logic. Information conditions are presented for the connectives and the way that they fit into the theory of information is discussed. (shrink)

Most commentators agree that (part of what) Kant means by characterizing the propositions of geometry as synthetic is that they are not true merely in virtue of logic or meaning, and that this characterization has something to do with his views about the construction of geometrical concepts in intuition. Many commentators regard construction in intuition as an essential part of geometrical proofs on Kant’s view. On this reading, the propositions of geometry are synthetic because the geometrical theorems cannot be proved (...) in purely conceptual or logical terms. Other commentators see the main role of pure intuition and the figures constructed in pure intuition in that they provide a model for Euclidean geometry. On views of this kind, the propositions of geometry are synthetic because the geometrical axioms are substantive truths about one of our forms of intuition. On the interpretation proposed in this essay, what Kant means by claiming that the propositions of geometry are synthetic is not only that the Euclidean axioms and theorems cannot be reduced to tautologies or logical truths, but also that they apply to really possible objects. Construction in intuition plays no essential role in (what we now call) ‘pure’ geometry on Kant’s view. But the fact that the concepts of geometry can be constructed in intuition is of crucial importance in the context of Kant’s transcendental philosophy of geometry, because, among other things, it allows him to explain how Euclidean geometry is possible as an a priori synthetic science in the sense just indicated.

Recent debates in the interpretation of Kant’s theoretical philosophy have focused on the nature of Kantian intuition and, in particular, on the question of whether intuitions depend for their existence on the existence of their objects. In this paper we show how opposing answers to this question determine different accounts of the nature of Kantian cognition and we suggest that progress can be made on determining the nature of intuition by considering the implications different views have (...) for the nature of cognition.

This commentary identifies two problems concerning the switch mechanism: The model explains too few instances of switching, and the switching mechanism itself seems fallible. The improvements we suggest are to clarify the nature of the competing intuitions as the initial intuition and its negation or alternative ways to solve the problem, and to incorporate cognitive disfluency into the switching mechanism.

In this paper I discuss some underlying motivations common to most strands of experimental philosophy, noting that most forms of experimental philosophy have a commitment to the claim that certain empirical evidence concerning the level of agreement on intuitive judgments across cultures, ethnic groups or socioeconomic strata impugns the role that intuitions play in traditional “armchair” philosophy. I then develop an argument to suggest that, even if one were to grant the truth of the data adduced by experimentalists regarding (...) the level of agreement—or lack thereof—regarding intuitive judgments among various groups, this would nevertheless not yet provide sufficient basis to reject the role of intuitions in traditional philosophical theorizing. Though this argument, if successful, will not prove fatal to all forms of experimental philosophy, it would limit the scope of experimental philosophical criticisms of traditional philosophical practice.

This book focuses on the very nature and function of intuitive thought. It presents an up-to-date scientific model on how the non-conscious and intuitive thought processes work in human beings. The model is based on mainstream theorizing on intuition, as well as qualitative meta-analysis of the empirical data available in the research literature. It combines recent work in the fields of philosophy of mind, cognitive psychology and positive psychology. While systematic research in intuition is relatively new, there is an (...) abundance of positions advocating more or less imaginative ideas of what intuition is about, ranging from quantum mechanical phenomena to new age ideologies. Research in the past few decades, in particular by proponents of the dual processing theory of thought such as Daniel Kahneman and Jonathan Evans, offers powerful tools to address and evaluate the question of intuition without the need to resort to spiritual entities. Within the framework of the dual processing theory, backed up by findings in positive psychology, intuition turns out to be the capacity to carry out complex cognitive operations within a specific domain of operations familiar to the agent.

Great intuitions are fundamental to conjecture and discovery in mathematics. In this paper, we investigate the role that intuition plays in mathematical thinking. We review key events in the history of mathematics where paradoxes have emerged from mathematicians' most intuitive concepts and convictions, and where the resulting difficulties led to heated controversies and debates. Examples are drawn from Riemannian geometry, set theory and the analytic theory of the continuum, and include the Continuum Hypothesis, the Tarski-Banach Paradox, and several works (...) by Gödel, Cantor, Wittgenstein and Weierstrass. We examine several fallacies of intuition and determine how far our intuitive conjectures are limited by the nature of our sense-experience, and by our capacities for conceptualization. Finally, I suggest how we can use visual and formal heuristics to cultivate our mathematical intuitions and how the breadth of this new epistemic perspective can be useful in cases where intuition has traditionally been regarded as out of its depth.

According to current methodological orthodoxy philosophers rely on intuitions about thought experiments to refute general claims about the nature of knowledge, freedom, thought, reference, justice, beauty, etc. Philosophers working under the banner of ‘negative experimental philosophy’ have criticized more traditional philosophers for relying on this method. They argue that intuitions about thought experiments are influenced by factors that are irrelevant to the truth of their contents. Cappelen and Deutsch defend traditional philosophy against this critique by rejecting the (...) picture of philosophical methodology it presupposes: philosophers do not really rely on intuitions. In this paper, I defend methodological orthodoxy by arguing that philosophers must rely on intuitions somewhere and that they do in fact often rely on intuitions about thought experiments. I also argue in favor of a reply to the negative experimental critique that is similar to at least part of Deutsch’s own. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The Nature of Proof in PsychiatryPaul Lieberman (bio)Keywordspsychotherapy process, knowledge and psychiatry, externalism, WittgensteinThis vivid clinical report illustrates recognizably, and provocatively, a number of routine, but often unexamined, clinical questions. In its few paragraphs, it depicts challenges that each practitioner confronts, and, in the flux of clinical work, addresses, however implicitly and imperfectly, every day: From what data, and by what processes, does a clinical formulation, or way (...) of understanding, come into being? How do we appraise its accuracy and adequacy? Of what value is even a well-substantiated understanding, in the mind of the therapist, to the patient? What is the power of empathy as a treatment tool? How do we assess someone's status as a “good candidate for therapy?” When, typically, only the outlines of a problem are visible, and its origins and implications are largely hidden, by what right do we recommend psychotherapy, and with what conception, at what level of detail, of what its outcome will be? These are among the questions that Dr. Bailey's story challenges us to address.They are clinical questions, of course, because they deal with empirical matters of fact—psychological processes, outcomes studies, and evidence. But they are also philosophical because, as Freud insisted and Dr. Bailey shows, information obtained in the clinical situation often has power and authority that lead us to believe we understand what is going on, understand the other person, even in the absence of scientifically tested hypotheses, or the clear application of research-based evidence. Interactions between people—including clinical interactions—have a life and ability to engage us. Their meanings can seem so transparent and convincing that no doubt or questioning may seem cogent. At their most powerful, such experiences can reawaken us to important realms of experience and feeling which we might, otherwise, forget, ignore, suppress, deny, or in other ways keep out of awareness; they have the potential to arouse us and reconnect us with truths that, once revived, can seem both valid and important—perhaps the kind of experience that we may derive from works of art or literature (in fact, Dr. Bailey's account could be seen as a clinical parable—meant to be neither true nor false, but instructive). But even less dramatic examples are commonplace: we do routinely claim to know and be able to interpret and understand the actions of other people from our everyday interactions with and observations of them.What is less clear is how to account for these convictions and how to appraise their value, because they do not derive from established scientific procedures. Clinical intuition has a role throughout medicine, but we usually expect it to be subjected later to more rigorous tests to establish the correct diagnosis. Yet, as Dr. Bailey's case illustrates, clinical intuition in the psychiatric encounter seems somehow different. When Colin [End Page 225] leads Dr. Bailey to the conclusion that a “painful lack of wounds” has made him depressed, we find this credible. It seems similarly credible that Dr. Bailey might be anxious about his own capacity to defend his young family, because he says he is, that he perceives Colin as testing his manhood or sincerity, because that seems to fit Colin's temperament, that being accurately understood is helpful, because most of us have had that experience and valued it, and that, most generally, an absence of challenge or of activity could be depressing. But suppose a patient believed that a painful lack of wounds produced diabetes instead of depression, or suppose he had developed epilepsy and attributed that to an absence of combat experience. We might see these as ‘pre-scientific’ or ‘hypothesis-generating’ (or worse). By contrast, it seems timid to consider psychiatric formulations to be always and only provisional or hypothetical.In what ways and to what extent should we expect psychiatry to be different, and why? Several considerations suggest that psychiatry's reasons are not, always and everywhere, the same as those of general medicine, nor are its objectives.In general medicine, we distinguish between signs and symptoms, on the one hand, and “underlying” disease processes, on the other. But in psychiatry, this distinction can be... (shrink)

Beliefs seem to be more significantly constrained by some norms than others e.g. one should only believe what they have sufficient evidence for, a belief that p is correct iff p is true etc. I call these norms, doxastic norms. Constitutivism is the view that doxastic norms are a constitutive feature of belief. I argue that this view is mistaken. In making this case, I come to defend views about the semantics of doxastic norms, the nature of belief, and (...) the value of truth. Doxastic norms are naturally stated in deontic terms. In the first chapter, I consider how we should best understand these statements, given that we likely don't control our beliefs in the same way that we do our actions. In the second chapter, I consider whether the account of religious belief given by either Ludwig Wittgenstein or Søren Kierkegaard provide a counterexample to constitutivism. In the third chapter, I argue that constitutivism can't account for certain intuitions about our reasons for belief. In the fourth chapter, I defend a descriptive account of belief in terms of the appearance of truth. In the fifth chapter, I show how my view can better account for the data which is thought by some to support constitutivism. In the final chapter, I describe how our reasons for belief might arise from our goals. (shrink)

The purpose of the paper is to cast doubt on the alleged intuitive or natural character of the skeptical argument about the external world. In §1, we examine a version of the skeptical argument based on the epistemic closure principle and the indifference principle. In §2, in order to deepen the view defended by Michael Williams, we offer a novel examination of the Cartesian skeptical argumentation to show that it is clear that the alleged naturalness claimed by the skeptic is (...) nowhere to be found in two arguments which can be found in such argumentative strategy; moreover, to reach her conclusion, the skeptic needs to commit to epistemological realism, namely, the claim that each of our beliefs belongs to an epistemological hierarchy based solely on its content. In §3, based on arguments inspired by Wittgenstein, contra epistemological realism, we show how each belief has a justificatory role based on its context. (shrink)

The debate over the grounds of full moral status relies heavily on the “method of cases.” In the method of cases intuitions about particular cases are taken as evidence for philosophical theories. Much in the debate over the grounds of full moral status turns on our intuitions regarding the moral status of individuals with intellectual disability. This paper argues that the intuitions of those in close personal relationships with individuals with intellectual disability are more reliable than the (...) intuitions of those who lack such a relationship. When theorizing about full moral status, we should privilege the intuitions of those who have a close personal relationship with an individual with intellectual disability. (shrink)

The cognitive anthropological approach has provided a powerful means of beginning to understand religious representations. I suggest that two extant approaches, despite their general plausibility, may not accurately characterise the detailed nature of those representations. A major source of this inaccuracy lies in the characterisation of negation of ontological properties, which gives rise to broader questions about their ontological determinacy and counter-intuitiveness. I suggest that a more plausible account may be forthcoming by allowing a more complex approach to the (...) representations, deriving from understanding their nature as concept combinations. Such an account also suggests an alternative approach to the role of deference in religious representations. In sum, the empirical and theoretical implications of a more fine-grained analysis of religious representations suggest a vindication of the cognitive anthropology approach to integrating culture and cognition.
