The paper presents a truth-maker semantics for Strict/Tolerant Logic (ST), which is the currently most popular logic among advocates of the non-transitive approach to paradoxes. Besides being interesting in itself, the truth-maker presentation of ST offers a new perspective on the recently discovered hierarchy of meta-inferences that, according to some, generalizes the idea behind ST. While fascinating from a mathematical perspective, there is no agreement on the philosophical significance of this hierarchy. I aim to show that there is no clear (...) philosophical significance of meta-inferences above the first level. (shrink)

I argue that logic is unlike science in its methodology, thus rejecting anti-exceptionalism about logic. Logic has a mathematical and a philosophical part. In its mathematical part, the methodology of logic is like that of mathematics, and no need to choose between theories arises in that part. In its philosophical part, the methodology of logic is like that of philosophy. Philosophy and mathematics are both unlike the empirical sciences in their methodology. So logic is unlike the empirical sciences in its (...) methodology. I end by looking at disagreements about the liar paradox as an example. (shrink)

This paper offers an account of deontic normativity in terms of attributive goodness. An action is permissible for S in C just in case there is a good practical inference available to S in C that results in S performing (or intending to perform) the action. The standards of goodness for practical inferences are determined by what is a good or bad exercise of the human capacity of practical reason, which is an attributive (and not a deontic) assessment.

I argue against abductivism about logic, which is the view that rational theory choice in logic happens by abduction. Abduction cannot serve as a neutral arbiter in many foundational disputes in logic because, in order to use abduction, one must first identify the relevant data. Which data one deems relevant depends on what I call one's conception of logic. One's conception of logic is, however, not independent of one's views regarding many of the foundational disputes that one may hope to (...) solve by abduction. (shrink)

I argue that the accounts of inference recently presented (in this journal) by Paul Boghossian, John Broome, and Crispin Wright are unsatisfactory. I proceed in two steps: First, in Sects. 1 and 2, I argue that we should not accept what Boghossian calls the “Taking Condition on inference” as a condition of adequacy for accounts of inference. I present a different condition of adequacy and argue that it is superior to the one offered by Boghossian. More precisely, I point out (...) that there is an analog of Moore’s Paradox for inference; and I suggest that explaining this phenomenon is a condition of adequacy for accounts of inference. Boghossian’s Taking Condition derives its plausibility from the fact that it apparently explains the analog of Moore’s Paradox. Second, in Sect. 3, I show that neither Boghossian’s, nor Broome’s, nor Wright’s account of inference meets my condition of adequacy. I distinguish two kinds of mistake one is likely to make if one does not focus on my condition of adequacy; and I argue that all three—Boghossian, Broome, and Wright—make at least one of these mistakes.

The new paradigm in the psychology of reasoning draws on Bayesian formal frameworks, and some advocates of the new paradigm think of these formal frameworks as providing a computational-level theory of rational human inference. I argue that Bayesian theories should not be seen as providing a computational-level theory of rational human inference, where by “Bayesian theories” I mean theories that claim that all rational credal states are probabilistically coherent and that rational adjustments of degrees of belief in the light of (...) new evidence must be in accordance with some sort of conditionalization. The problems with the view I am criticizing can best be seen when we look at chains of inferences, rather than single-step inferences. Chains of inferences have been neglected almost entirely within the new paradigm. (shrink)

Nontransitive responses to the validity Curry paradox face a dilemma that was recently formulated by Barrio, Rosenblatt and Tajer. It seems that, in the nontransitive logic ST enriched with a validity predicate, either you cannot prove that all derivable metarules preserve validity, or you can prove that instances of Cut that are not admissible in the logic preserve validity. I respond on behalf of the nontransitive approach. The paper argues, first, that we should reject the detachment principle for naive validity. (...) Secondly, I show how to add a validity predicate to ST while avoiding the dilemma. (shrink)

The paper offers an account of inference. The account underwrites the idea that inference requires that the reasoner takes her premises to support her conclusion. I reject views according to which such ‘takings’ are intuitions or beliefs. I sketch an alternative view on which inferring consists in attaching what I call ‘inferential force’ to a structured collection of contents.

According to McHugh and Way reasoning is a person-level attitude revision that is regulated by its constitutive aim of getting fitting attitudes. They claim that this account offers an explanation of what is wrong with reasoning in ways one believes to be bad and that this explanation is an alternative to an explanation that appeals to the so-called Taking Condition. I argue that their explanation is unsatisfying.

I argue that recent attempts to show that meaning and content are not normative fail. The two most important arguments anti-normativists have presented are what I call the ‘argument from constitution’ and the ‘argument from guidance’. Both of these arguments suffer from the same basic problem: they overlook the possibility of focusing on assessability by norms, rather than compliance with norms or guidance by norms. Moreover, I argue that the anti-normativists arguments fail even if we ignore this basic problem. Thus, (...) we have not been given good reasons to think that normativism is false. (shrink)

While we can judge and believe things by merely accepting testimony, we cannot make inferences by merely accepting testimony. A good theory of inference should explain this. The theories that are best suited to explain this fact seem to be theories that accept a so-called intuitional construal of Boghossian’s Taking Condition.

I am presenting a sequent calculus that extends a nonmonotonic consequence relation over an atomic language to a logically complex language. The system is in line with two guiding philosophical ideas: (i) logical inferentialism and (ii) logical expressivism. The extension defined by the sequent rules is conservative. The conditional tracks the consequence relation and negation tracks incoherence. Besides the ordinary propositional connectives, the sequent calculus introduces a new kind of modal operator that marks implications that hold monotonically. Transitivity fails, but (...) for good reasons. Intuitionism and classical logic can easily be recovered from the system. (shrink)

The perhaps most important criticism of the nontransitive approach to semantic paradoxes is that it cannot truthfully express exactly which metarules preserve validity. I argue that this criticism overlooks that the admissibility of metarules cannot be expressed in any logic that allows us to formulate validity-Curry sentences and that is formulated in a classical metalanguage. Hence, the criticism applies to all approaches that do their metatheory in classical logic. If we do the metatheory of nontransitive logics in a nontransitive logic, (...) however, there is no reason to think that the argument behind the criticism goes through. In general, asking a logic to express its own admissible metarules may not be a good idea. (shrink)

The paper argues for a version of the Guise of the Good thesis, namely the claim that if someone acts as the result of practical reasoning, then she takes her premises to jointly provide a sufficient and undefeated reason for her action. I argue for this by showing, first, that it is an application of Boghossian's Taking Condition on inference to practical reasoning and, second, that the motivations for the Taking Condition for theoretical reasoning carry over to practical reasoning. I (...) end by arguing that this version of the Guise of the Good withstands standard objections. (shrink)

Some philosophers have recently argued that there are no diachronic norms of epistemic rationality, that is, that there are no norms regarding how you should change your attitudes over time. I argue that this is wrong on the grounds that there are norms governing reasoning.

Some think that logic concerns the “laws of truth”; others that logic concerns the “laws of thought.” This paper presents a way to reconcile both views by building a bridge between truth-maker theory, à la Fine, and normative bilateralism, à la Restall and Ripley. The paper suggests a novel way of understanding consequence in truth-maker theory and shows that this allows us to identify a common structure shared by truth-maker theory and normative bilateralism. We can thus transfer ideas from normative (...) bilateralism to truth-maker theory, such as non-transitive solutions to paradox, and vice versa, such as notions of factual equivalence and containment. (shrink)

It is often assumed that neo-Aristotelian virtue ethics postulates an obligation to be a good human being and that it derives further obligations from this idea. The paper argues that this assumption is false, at least for Philippa Foot’s view. Our argument blocks a widespread objection to Foot’s view, and it shows how virtue ethics in general can neutralize such worries.

For semantic inferentialists, the basic semantic concept is validity. An inferentialist theory of meaning should offer an account of the meaning of "valid." If one tries to add a validity predicate to one's object language, however, one runs into problems like the v-Curry paradox. In previous work, I presented a validity predicate for a non-transitive logic that can adequately capture its own meta-inferences. Unfortunately, in that system, one cannot show of any inference that it is invalid. Here I extend the (...) system so that it can capture invalidities. (shrink)

We sometimes violate social norms in order to express our views and to trigger public debates. Many extant accounts of social norms don’t give us any insight into this phenomenon. Drawing on Cristina Bicchieri’s work, I am putting forward an empirical hypothesis that helps us to understand such norm violations. The hypothesis says, roughly, that we often adhere to norms because we are systematically blind to norm-violating options. I argue that this hypothesis is independently plausible and has interesting consequences. It (...) implies, e.g., that some experimental paradigms for investigating social norms have hitherto unnoticed shortcomings. (shrink)

The paper presents teleo-inferentialism, which is a novel meta-semantic theory that combines advantages of teleosemantics and normative inferentialism. Like normative inferentialism, teleo-inferentialism holds that contents are individuated by the norms that govern inferences in which they occur. This allows teleo-inferentialism to account for sophisticated concepts. Like teleosemantics, teleo-inferentialism explains conceptual norms in a naturalistically acceptable way by appeal to the broadly biological well-functioning of our innate capacities. As a test-case for teleo-inferentialism, I discuss how the view handles Kripkenstein-style meaning skepticism.

In Kapitel 5 dieses Buches wurde mit dem ontologischen Sextett eine Klassifizierung der Realität vorgestellt, die das klassische Aristotelische Viereck erweitert, indem sie Einzeldinge und Universalien in insgesamt sechs Kategorien umfaßt. Zwischen den Entitäten dieser Kategorien sind bestimmte Beziehungen postuliert worden, wie zum Beispiel Inhärenz, Partizipation, Instantiierung, Exemplifizierung und Charakterisierung. In diesem Kapitel soil der Frage nachgegangen werden, wie eben diese Beziehungen zwischen den Entitäten dieser Kategorien genauer charakterisiert und die sie bezeichnenden relationalen Ausdrücke eindeutig formal definiert werden konnen.

According to simulationism, the function of episodic memory is not to remember the past, but to help construct representations of possible future episodes, by drawing together features from different experiential sources. This article suggests that the relationship between the traditional storehouse view, on which the function of memory is remembering, and the simulationist approach is more complicated than has been typically acknowledged. This is attributed, in part, to incorrect interpretations of what remembering on the storehouse view requires. Further, by appeal (...) to function pluralism, the article questions both the assumption that the traditional view and simulationism are inconsistent, and the simulationist’s inference to the best explanation strategy that is based upon this assumption. The article then provides an evaluation of the simulationist argument against the traditional view, and finds it in need of further support. (shrink)

So-called optimists about moral testimony argue, against pessimists, that, ceteris paribus, we ought to accept and act in accordance with trustworthy, pure moral testimony. I argue that even if we grant this, we need to explain why moral testimony cannot make us more virtuous. I offer an explanation that appeals to the fact that we cannot share inferential abilities via testimony. This explanation is compatible with the core commitments of optimism, but it also allows us to see what is right (...) about pessimism. (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.

This paper argues that the Islamic metaphysical vision finds its Western philosophical counterpart in Anna-Teresa Tymienecka's Phenomenology of Life. Comparative analysis of the main categories and strategies of knowledge in Islamic metaphysics and the Phenomenology of Life demonstrates obvious similarities, but also significant distinctions whereby the systems can be viewed as complementary. Tymieniecka’s philosophy begins with epoché on preceding philosophical knowledge, while Islamic philosophy begins with revelation. Tymieniecka uses presuppositionless phenomenological direct intuition combined with reflective analysis, while Sufi metaphysics combines (...) logic, intuitio,n and reliance on the experience attained in states of mystical perception. Unification of Reality and realization of truth in the Phenomenology of Life is attained via phenomenological intuition of life in all forms of experience, and in Islam, via certainty attained in religious experiences of unveiling. Due to its refocusing on the dynamic moments of the ontopoiesis of life, Tymieniecka’s ontology serves as a possible solution to the problems incurred by the more static metaphysical vision of Reality in Sufism.

Intellectualism is the claim that practical knowledge or ‘know-how’ is a kind of propositional knowledge. The debate over Intellectualism has appealed to two different kinds of evidence, semantic and scientific. This paper concerns the relationship between Intellectualist arguments based on truth-conditional semantics of practical knowledge ascriptions, and anti-Intellectualist arguments based on cognitive science and propositional representation. The first half of the paper argues that the anti-Intellectualist argument from cognitive science rests on a naturalistic approach to metaphysics: its proponents assume that (...) findings from cognitive science provide evidence about the nature of mental states. We demonstrate that this fact has been overlooked in the ensuing debate, resulting in inconsistency and confusion. Defenders of the semantic approach to Intellectualism engage with the argument from cognitive science in a way that implicitly endorses this naturalistic metaphysics, and even rely on it to claim that cognitive science support Intellectualism. In the course of their arguments, however, they also reject that scientific findings can have metaphysical import. We argue that this situation is preventing productive debate about Intellectualism, which would benefit from both sides being more transparent about their metaphilosophical assumptions. (shrink)

Accounts of the concepts of function and dysfunction have not adequately explained what factors determine the line between low‐normal function and dysfunction. I call the challenge of doing so the line‐drawing problem. Previous approaches emphasize facts involving the action of natural selection (Wakefield 1992a, 1999a, 1999b) or the statistical distribution of levels of functioning in the current population (Boorse 1977, 1997). I point out limitations of these two approaches and present a solution to the line‐drawing problem that builds on the (...) second one. (shrink)

In this comprehensive interview with Charles Taylor, the focus is put on the conceptual level. Taylor reflects on the relationship between history, narrativity and social critique, between social imaginaries and social change, and between his own thought and that of Cambridge School history of ideas, Nietzschean genealogy, Frankfurt School critical theory, and agonistic approaches to the political. This interview not only captures the tremendous breadth and range of Taylor’s theoretical interests, it also vindicates his contention that the common thread of (...) his oeuvre is the attempt to work out a non-reductive, non-mechanistic, non-atomistic philosophical anthropology. Still, it offers new insights into Taylor's most recent thinking and his intellectual engagement with the challenges of our time. (shrink)

The paper presents an exhaustive menu of nonmonotonic logics. The options are individuated in terms of the principles they reject. I locate, e.g., cumulative logics and relevance logics on this menu. I highlight some frequently neglected options, and I argue that these neglected options are particularly attractive for inferentialists.

Similarly to other accounts of disease, Christopher Boorse’s Biostatistical Theory (BST) is generally presented and considered as conceptual analysis, that is, as making claims about the meaning of currently used concepts. But conceptual analysis has been convincingly critiqued as relying on problematic assumptions about the existence, meaning, and use of concepts. Because of these problems, accounts of disease and health should be evaluated not as claims about current meaning, I argue, but instead as proposals about how to define and use (...) these terms in the future, a methodology suggested by Quine and Carnap. I begin this article by describing problems with conceptual analysis and advantages of “philosophical explication,” my favored approach. I then describe two attacks on the BST that also question the entire project of defining “disease.” Finally, I defend the BST as a philosophical explication by showing how it could define useful terms for medical science and ethics.

This volume presents discussions on a wide range of topics focused on eco-phenomenology and the interdisciplinary investigation of contemporary environmental thought. Starting out with a Tymieniecka Memorial chapter, the book continues with papers on the foundations, theories, readings and philosophical sources of eco-phenomenology. In addition, it examines issues of phenomenological anthropology, ecological perspectives of the human relationship to nature, and phenomenology of the living body and the virtual body. Furthermore, the volume engages in a dialogue with contemporary behavioral sciences on (...) topics such as eco-alienation, sustainability, and the human relationship to the earth in the context of the cosmos.

In substructural logics, structural principles may hold in some fragments of a consequence relation without holding globally. I look at this phenomenon in my preferred substructural logic, in which Weakening and Cut fail but which is supra-intuitionistic. I introduce object language operators that keep track of the admissibility of Weakening and of intuitionistic implications. I end with some ideas about local transitivity.

The paper aims to clarify the role of the meaning of life in Anselm Müller’s philosophy. Müller says that the ethically good life is the life of acting well, and acting well requires at least a rough conception of the meaning of life, or a conception of what makes a life go well. But why is such a conception required and what does it mean to have such a conception? I argue that such a conception cannot provide us with ultimate (...) ends in our practical deliberations. Nor can its role be merely to provide a standard against which practical reasoning can be assessed. Rather, our conception of the meaning of life is, in the first instance, that which allows us, in our practical reasoning, to see certain considerations as good reasons for certain actions and to weigh reasons for and against different options. One upshot of my interpretation is that Müller should be more optimistic about philosophy’s ability to answer the question of the meaning of life than he allows himself to be. (shrink)

The Negation Problem states that expressivism has insufficient structure to account for the various ways in which a moral sentence can be negated. We argue that the Negation Problem does not arise for expressivist accounts of all normative language but arises only for the specific examples on which expressivists usually focus. In support of this claim, we argue for the following three theses: 1) a problem that is structurally identical to the Negation Problem arises in non-normative cases, and this problem (...) is solved once the hidden quantificational structure involved in such cases is uncovered; 2) the terms ‘required’, ‘permissible’, and ‘forbidden’ can also be analyzed in terms of hidden quantificational structure, and the Negation Problem disappears once this hidden structure is uncovered; 3) the Negation Problem does not arise for normative language that has no hidden quantificational structure. We conclude that the Negation Problem is not really a problem about expressivism at all but is rather a feature of the quantificational structure of the required, permitted, and forbidden. (shrink)

In Chapter 8 of The Language Animal, Charles Taylor claims that narratives are unsubstitutable for an appropriate understanding of social life and ‘human affairs’ in general. In order to identify open questions in his argumentation as well as unwanted consequences of his outlook, I proceed in three consecutive steps. I first problematize Taylor’s distinction between laws and stories, then go on to address his intentional blurring of stories and histories, and finally suggest that the concept of genealogy might be a (...) promising candidate for describing Taylor’s approach, concluding that he implicitly forms the equation: narrative equals history equals critique.

"Modern History" versions of the etiological theory claim that in order for a trait X to have the proper function F, individuals with X must have been recently favored by natural selection for doing F (Godfrey-Smith 1994; Griffiths 1992, 1993). For many traits with prototypical proper functions, however, such recent selection may not have occurred: traits may have been maintained due to lack of variation or due to selection for other effects. I examine this flaw in Modern History accounts and (...) offer an alternative etiological theory, the Continuing Usefulness account, which appears to avoid such problems. (shrink)

Two brief Late Antique religious texts, respectively by the monk Theophanis and by Monoimus the Arab, present an interesting problem of whether they embody the authors’ experience, or whether they are merely literary constructs. Rather than approaching this issue through the lens of theory, the article shows how phenomenological analysis and studies of living subjectivity can be engaged with the text in order to clarify the contents of introspective experience and the genesis of its religious connotations. The analysis uncovers a (...) previously unnoticed form of embodied introspective religious experience which is structured as a ladder with a distinct internal structure with the high degree of synchronic and diachronic stability. This approach also helps one identify the specific introspective techniques in the canonical and non-canonical literature of early Christian tradition, as related to the concepts of “ theosis ” and “ kenosys ”, as well as to suggest some neurological correspondents of religious cognition.

Terraforming is a process of planetary engineering by which the extant environment of a planetary body is transformed into an environment capable of supporting human inhabitants. The question I would like to consider in this paper is whether there is any reason to believe that the terraforming of another planet—for instance, the terraforming of Mars—is morally problematic. Topics related to the human exploration of space are not often discussed in philosophical circles. Nevertheless, there exists a growing body of philosophical literature (...) dedicated to sorting out the moral implications of the use of resources from (and in) space. Most of this literature is produced as environmental philosophy. Questions of .. (shrink)

I argue that ductal carcinoma in situ (DCIS), the tumor most commonly diagnosed by breast mammography, cannot be confidently classified as cancer, that is, as pathological. This is because there may not be dysfunction present in DCIS—as I argue based on its high prevalence and the small amount of risk it conveys—and thus DCIS may not count as a disease by dysfunction-requiring approaches, such as Boorse’s biostatistical theory and Wakefield’s harmful dysfunction account. Patients should decide about treatment for DCIS based (...) on the risks it poses and the risks and benefits of treatment, not on its disease status. (shrink)

Review of Timo-Peter Ertz's "Regel und Witz. Wittgensteinsche Perspektiven auf Mathematik, Sprache und Moral," Berlin & New York: de Gruyter, 2008.

Dretske has provided very influential arguments that there is a difference between our sensory awareness of objects and our awareness of facts about these objects—that there is a difference, for example, between seeing x and seeing that x is F. This distinction between simple and epistemic seeing is a staple of the philosophy of perception. Memory is often usefully compared to perception, and in this spirit I argue for the conditional claim that if Dretske’s arguments succeed in motivating the posit (...) of simple seeing, then parallel arguments should equally motivate a posit I call simple remembering. Simple remembering would be a conscious form of memory about an object or event which is prior to and independent of any beliefs the subject may or may not form about the object or event simply remembered.

This paper critiques the view, widely held by philosophers of mind and cognitive scientists, that psychological explanation is a matter of ascribing propositional attitudes (such as beliefs and desires) towards language-like propositions in the mind, and that cognitive mental states consist in intentional attitudes towards propositions of a linguistic quasi-linguistic nature. On this view, thought is structured very much like a language. Denial that propositional attitude psychology is an adequate account of mind is therefore, on this view, is tantamount to (...) eliminative materialism, the denial that human beings are thinking beings. -/- I dispute this on the basis of recent work in cognitive psychology and artificial intelligence. Mental models theory, on which thought is better understood as nonpropositional intentional psychology, accords better with the evidence and offers an alternative view to propositional attitude psychology -- one that means that the denial that that is propositional is not eliminative. However, I argue that propositional attitude psychology is a useful idealization, as classical mechanics is of relativity theory, strictly but not radically false, and useful for prediction and indeed, as long as its idealized character is born in mind, for explanation of behavior.

Patients should not always receive hard data about the risks and benefits of a medical intervention. That information should always be available to patients who expressly ask for it, but it should be part of standard disclosure only sometimes, and only for some patients.

Debate about legal and policy reform has been haunted by a pernicious confusion about human nature, the idea that it is a set of rigid dispositions, today generally conceived as genetic, that is manifested the same way in all circumstances. Opponents of egalitarian alternatives argue that we cannot depart far from the status quo because human nature stands in the way. Advocates of such reforms too often deny the existence of human nature because, sharing this conception, they think it would (...) prevent changes they deem desirable. Both views rest on deep errors about what it is to have a nature and how genetics works. Human nature, like the nature of anything else, is a set of potentials to behave certain ways in given environments, not a nonsocial genetic something that inevitably produces the same result in any environment. To say that existing inequalities, are due to our genes, inalterable because heritable, ignores that genetic propensities may be differently manifested in different environments. Heritability has meaning only relative to an environment and a population and implies nothing about inevitability. A better sort of inegalitarian argument is that a proposed reform, given our nature, would be too costly even if possible. However, this sort of argument is too rarely supported by evidence and generally ignores the costs of existing inequalities. But egalitarians err in supposing that, if behavior is unconstrained by biology, the status quo is easily alterable. The environment may be extremely hard to change. Legal and policy debate should adopt a correct understanding of human nature as a set of propensities and ask of any proposed reform agreed to be otherwise desirable what and how alterable are its causes, genetic, environmental, or more accurately both.

The Gathas, a corpus of seventeen poems in Old Avestan composed by the ancient Iranian poet-priest Zarathushtra (Zoroaster) ca. 1200 B.C.E., is the foundation document of Zoroastrian religion. Even though the dualistic axiology of the Gathas has been widely noted, it has proved very difficult to understand the meaning and genre of the corpus or the position of Zarathushtra’s ideas with regard to other religious philosophies. Relying on recent advances in translation and decryptions of Gathic poetry, I shall here develop (...) a philosophical interpretation of the Gathas, including, as shall be discussed here in detail, explication of the revelation he reports in the poem known as Yasna 30. I argue that, similarly to Marx, Henry, and Schutz, Zarathushtra connects social criticism with an original philosophy of (inter)subjectivity and existential reflection, placing his account in the context of a fully developed metaphysics which includes the human-divine sharing of mental properties. I show that in order to accommodate this complicated problematic, Zarathushtra uses the vehicle of multiple realities. Reflecting the spontaneity of life, the dynamics of various ontological modes in the text create a reference to subjectivity. A description of the dream in Yasna 30 is sufficiently within the limits of possibility for a dream experience, and thereby delivers three original phenomenological reductions. The reductions initiate a genetic account of the phenomenalization of invisible impulses which give rise to moral choices, and define the human-divine relationship. The opposing moral choices open into a reverse axiological intentionality in the sphere of intersubjectivity, and are said to plot life for the rightful and lifelessness for the wrongful. It can be concluded that Zarathushtra’s theism and views of the social world are “the first philosophy”, with a unique and original phenomenological ontology of intersubjectivity at its core.

Philosophers have argued that on the prevailing theory of mind, functionalism, the fact that mental states are multiply realizable or can be instantiated in a variety of different physical forms, at least in principle, shows that materialism or physical is probably false. A similar argument rejects the relevance to psychology of connectionism, which holds that mental states are embodied and and constituted by connectionist neural networks. These arguments, I argue, fall before reductios ad absurdam, proving too much -- they apply (...) as well to genes, which are multiply realizable, but the reduction of which to DNA is one the core cases of scientific reductive explanation, a reduction if anything is. -/- I suggest that psychology, like biology, be what I call "provincialized," abandon claims to universal validity, except as an idealization, and treat different classes of cognizers differently from an an explanatory perspective. This would permit specifies specific, or more precisely, provincial reductions of different psychologies that might be multiply realized if such reductions were available. Connectionism may be the foundation of a reduction of human psychology, and thus biology and connectionism retain their relevance to psychology, and physicalism or materialism is consistent with functionalism.

Obsessive-compulsive disorder is a commonly occurring neuropsychiatric condition characterized by bothersome intrusive thoughts and urges that frequently lead to repetitive dysfunctional behaviours such as excessive handwashing. There are well-documented alterations in cerebral function which appear to be closely related to the manifestation of these symptoms. Controlled studies of cognitive-behavioural therapy techniques utilizing the active refocusing of attention away from the intrusive phenomena of OCD and onto adaptive alternative activities have demonstrated both significant improvements in clinical symptoms and systematic changes in (...) the pathological brain circuitry associated with them. Careful investigation of the relationships between the experiential and putative neurophysiological processes involved in these changes can offer useful insights into volitional aspects of cerebral function.
