Introspection is a fundamental part of our mental lives. Nevertheless, its reliability and its underlying cognitive architecture have been widely disputed. Here, I propose a principled way to model introspection. By using time-tested principles from signal detection theory (SDT) and extrapolating them from perception to introspection, I offer a new framework for an introspective signal detection theory (iSDT). In SDT, the reliability of perceptual judgments is a function of the strength of an internal perceptual response (signal- to-noise ratio) which is, (...) to a large extent, driven by the intensity of the stimulus. In parallel to perception, iSDT models the reliability of introspective judgments as a function of the strength of an internal introspective response (signal-to-noise ratio) which is, to a large extent, driven by the intensity of conscious experiences. Thus, by modelling introspection after perception, iSDT can calibrate introspection’s reliability across a whole range of contexts. iSDT offers a novel, illuminating way of thinking about introspection and the cognitive processes that support it.

In this paper, I discuss the legitimacy of using the term “to know” in morality and I develop an approach based on Kantian morality. In my analysis, I take the notion “to know” in the sense that Timothy Williamson does. That is to say, I regard it in opposition to the perspectives that claim “knowledge is jus-tified true belief”. Therefore, in the first part, I briefly introduce “knowledge first epistemology”. In the second part, I build a perspective pointing to the (...) strong correlation between acting and knowing. After that, I provide an analysis of Kantian morality in connection with my discussion. I show how Kant argues for a lawful certainty in morality that allows us to use the verb “know” (in the sense that is evaluated in the first part of this paper). In the next part, I comment on the un-analyzability of knowing in the practical sphere with reference to free will. In my conclusion, upon a general review of the paper, I introduce very briefly an alternative epistemology from Islamic thought regarding the theoreti-cal and practical sphere distinctions. (shrink)

This article presents a response to Richard Rorty's paper "Is Philosophy Relevant to Business Ethics?" The author questions Rorty's views on the depreciation of the role of philosophy in applied ethics, and outlines four reasons why philosophy retains its relevance. The author addresses the role of moral reasoning in the development of the moral imagination. The author also concludes that humans have the means necessary to make moral progress and are capable of moral reasoning, and need only to develop a (...) strong moral imagination. (shrink)

In the introduction to his famous book, La Science et l’hypothèse, Poincaré remarks on the necessary role and legitimacy of hypotheses. He establishes a triple classification of hypotheses, dividing them into verifiable, useful, and apparent. However, in chapter 9, entitled ‘Les hypothèses en physique’, he gives a slightly different triadic classification: natural hypotheses, indifferent hypotheses, and real generalizations. The origin of this second classification is a lecture given at the International Congress of Physics, Paris, 1900. What are the similarities and (...) differences between these two classifications? My main purpose is to provide a possible equivalence between the two classifications in order to clarify the role of hypotheses in Poincaré’s epistemology of natural science. The discussion will be based on the two fundamental texts mentioned above and on the contrast between Poincaré’s use of the notion of hypothesis and that of some of his contemporaries. (shrink)

ABSTRACTVarious authors, including Friedrich Nietzsche and George Steiner, have argued that the tragic worldview, as we find it expressed in Greek tragedy, has become an entirely incomprehensible phenomenon for modern man. The claim defended in this article radically opposes this view. It is argued that tragedy can still teach us something today, and maybe even more so now than in the many intervening centuries that separate us from her days of glory in the fifth century BCE. The tragic reveals itself (...) once more in modern society, and nowhere more clearly than in technology, the domain in which we believed the tragic had been domesticated or even eliminated. Referring to the tragic humanism in Michel Houellebecq’s novels The Elementary Particles and The Possibility of an Island it is argued that it is precisely in modern technologies that we experience the rebirth of the tragic.

For Jerry Fodor, Hume’sTreatise of Human Natureis “the foundational document of cognitive science” whose significance transcends mere historical interest: it is a source of theoretical inspiration in cognitive psychology. Here I am going to argue that those reading Hume along Fodor’s lines rely on a problematic, albeit inspiring, construction of Hume’s science of mind. My strategy in this paper is to contrast Fodor’s understanding of the Humean mind (consonant with the widely received view of Hume in both cognitive science and (...) much of Hume scholarship) with an alternative understanding that I propose. I thereby intend to show that the received view of Hume’s science of mind can be fruitfully revised while critically engaging with Fodor’s contemporary appropriation. Consequently, I use this occasion to put forward a rather unorthodox interpretation of Hume’s theory in dialogue with Fodor as my guide. (shrink)

This essay addresses the questions of whether the givenness of God is something possible, intelligible—and, if so, what such givenness might involve. In the interest of situating these questions in historical context, I first summarize Kant’s, Hegel’s, and Habermas’s respective accounts of the relationship between belief in God and philosophical knowledge. I then further situate critical philosophy’s appropriation of God by way of a discussion of how some of this appropriation’s fiercest critics—existentialists such as Sartre, Shestov, and Kierkegaard—object to its (...) gambit of using God to serve moral and cultural goals even as it denies God’s actual existence. Though this objection is a salient one, it leaves something to be desired. For although the existentialists may demonstrate what is misguided about the philosophers’ God, they do not have anything especially compelling to say about whether or how God can be given experientially. I address this aporia by exploiting what I take to be a happy intersection between the phenomenological conception of the saturated phenomenon and two moods—agape love and ecstatic joy—the mystical tradition frequently attributes to the nature of divine givenness. I argue that, when mystical experience is situated within the framework of saturated phenomena rather than within the Kantian enclosures of phenomenality, two intriguing possibilities emerge. First, it seems plausible that the religious experience of the mystic can, in principle, involve the very givenness of God that Kant and his heirs denied to be possible. Second, though phenomenology has yet to provide a complete positive portrait of the religious life, the mystical tradition emerges as a legitimate, invaluable source with which such a phenomenological portrait might begin.

Tom Hanauer's thoughtful discussion of my article “The Pleasures of Contra-purposiveness: Kant, the Sublime, and Being Human” puts pressure on two important issues concerning the affective phenomenology of the sublime. My aim in that article was to present an analysis of the sublime that does not suffer from the problems identified by Jane Forsey in “Is a Theory of the Sublime Possible?”. I argued that Kant's notion of reflective judgment can help with this task, because it allows us to capture (...) the experience of failure that characterizes the sublime without committing us to ontologically transcendent items. In a significant departure from Kant, however, my account does not require references to our moral vocation to explain the pleasure we take in the sublime; the pleasure comes from getting the right measure of our agency. For Hanauer, trouble for my analysis comes both from the discursive presentation of the sublime, its focus on judgment, and from the removal of references to our moral vocation. (shrink)

This paper aims at contributing to the ongoing efforts to get a firmer grasp of the systematic significance of the entanglement of idealism and empiricism in Helmholtz's work. Contrary to existing analyses, however, the focal point of the present exposition is Helmholtz's attempt to articulate a psychological account of objectification. Helmholtz's motive, as well as his solution to the problem of the object are outlined, and interpreted against the background of his scientific practice on the one hand, and that of (...) empiricist and (transcendental) idealist analyses of experience on the other. The specifically psychological angle taken, not only prompts us to consider figures who have hitherto been treated as having only minor import for Helmholtz interpretation (most importantly J.S. Mill and J.G. Fichte), it furthermore sheds new light on some central tenets of the latter's psychological stance that have hitherto remained underappreciated. For one thing, this analysis reveals an explicit voluntarist tendency in Helmholtz's psychological theory. In conclusion, it is argued that the systematic significance of Helmholtz's empirico-transcendentalism with respect to questions of the mind is best understood as an attempt to found his empirical theory of perception in a second order, normative account of epistemic subjectivity.

In this paper I made an attempt to discuss how the concept of alienation has been discussed in G.W.F. Hegel’s (1770–1831) social philosophy. In Hegel’s philosophy, alienation is part of the process of self-creativity and self-discovery. According to Hegel, initially our consciousness is alienated from itself. It cannot understand its own true nature. In order to realize its own true nature consciousness’s needs to develop absolute knowledge. The development of consciousness’s absolute knowledge is possible through the overcoming of self-alienation of (...) consciousness. Here, concept of alienation plays an important role in bringing consciousness to the shape of itself called absolute knowing. According to Hegel, consciousness cannot easily know itself with certainty. Consciousness has to develop its self-understanding to fully understand itself. In his discussion of the concept of alienation Hegel compares the dialectic of self-consciousness and consciousness which is not self-realised with the famous dialectic of the lord and the bondsman. It means while discussing the relation of lord and bondsman Hegel compares lord with independent consciousness and bondsman with dependent consciousness. This dialectic of lord and bondsman is sometimes referred to as the dialectic of the master and the slave relationship. In the productive system when everybody regards themselves to be producer and as a member of productive activity, when everybody participates in the large collaborative activity, then there exists no alienation in the society. But when people forget this identity then alienation arises in the society. Hegel thinks that when our consciousness reaches at the stage of itself called Absolute knowledge then it clearly comes to know that it is a differentiated spiritual unity of subjectivity and objectivity. Then it comes to know its own true nature and it overcomes its self-alienation. In the same way in society people overcome their self-alienation when everyone can think themselves to be a part of the whole community. In the present study, I shall deal with how Hegel has applied the concept of alienation in his social philosophy and how does he try to show that through overcoming his alienation a man gets united with the other or the whole community.

What is called “time travel” cinema is but one aspect in a tripartite series of interweaving modes of disjunctive narration which is also – simultaneously – a cinema of “many worlds” and “altered states”. Exploiting Gilles Deleuze's three syntheses of time, space, and consciousness from Difference and Repetition (1968) allows a conceptual development of these cinematic series through three popular Hollywood film cycles beginning with Planet of the Apes (Franklin J. Schaffner, 1968), The Terminator (James Cameron, 1984), and Back to (...) the Future (Robert Zemeckis, 1985). In so doing, film and philosophy are deployed as two series which together create inexhaustible atemporal, aspatial, and ahuman disjunctions, ungrounding everyday spatio-temporal identities, and affirming productive images of cinematic thought.

In this article, I demonstrate that Friedrich Nietzsche offers us a unique form of hermeneutic critique. In particular, I contend that when reading Nietzsche’s perspectivism and will to power in light of each other, they provide us with the tools to overcome habits of interpretation through the concepts of genealogy and creative hermeneutics. I show this in three sections. In section one, I introduce Nietzsche’s perspectivism and situate it within his concept of the will to power. In doing so, I (...) demonstrate that interpretations exist amidst a complex field of agonistic, reciprocal relations in life’s constant production of meaning. In section two, I then analyze how certain interpretations sediment into habits, forming harmful blind spots in interpretive activity. Such habits, Nietzsche shows, when privileged as prima facie ‘True’ and left uncontested exclude different ways of interpreting and existing, stagnating the production of meaning and denying the agonistic conditions of life. In the final section, I argue that Nietzsche critiques such habits in the two directions of genealogy and creative hermeneutics. Through the backward approach of genealogy, Nietzsche problematizes the habit, excavates its lowly origin, and deconstructs its supposed universality. Through the forward approach of creative hermeneutics, he overcomes and reinterprets them out of their origins, experiments with difference and multiplicity, and engages in an ongoing critique to open up new perspectives.

The divest movement has focused attention on strategic and ethical differences in the practice of socially responsible investing and highlighted an unnecessary bifurcation of best-of-class engagement and divestment. Although best-of-class engagement is favored as a contemporary and pragmatic approach, this paper calls for a more pronounced recognition of absolute dealbreakers and divestment as an underpinning for best-of-class engagement. After linking divestment and best-of-class engagement to their foundations of absolutism and relativism, respectively, I critique best-of-class engagement and argue that without a (...) distinct and explicit role for divestment, best-of-class strategies are ethically and strategically fraught. Following a discussion of which types of issues suggest divestment or best-of-class engagement, I identify the Norway Government Pension Fund as a noteworthy example, and posit that divestment and engagement are best presented and employed in tandem, particularly for issues that have yet to be addressed by law and convention.

In this paper, I explore various views on which mind-body dualism is true, but the soul is located in the body. I argue that this sort of dualism (which I call 'somatic dualism') once was a not-uncommon view in the philosophy of mind. I also argue that it has the resources to reply to some of the problems thought to affect Cartesian dualism.

Psychiatry widely assumes an internalist biomedical model of mental illness. I argue that many of psychiatry’s diagnostic categories involve an implicit commitment to constitutive externalism about mental illness. Some of these categories are socially externalist in nature.

How, asks Françoise Dastur, can philosophy account for the sudden happening and the factuality of the event? Dastur asks how phenomenology, in particular the work of Heidegger, Husserl, and Merleau-Ponty, may be interpreted as offering such an account.

We should connect them; openness to phenomena must be identified with (...) openness to unpredictability." The article offers reflections in these terms on a phenomenology of birth. (shrink)

Active externalism (also known as the extended mind hypothesis) says that we use objects and situations in the world as external memory stores that we consult as needs dictate. This gives us economies of storage: We do not need to remember that Bill has blue eyes and wavy hair if we can acquire this information by looking at Bill. I argue for a corollary to this position, which I call ‘internalism.’ Internalism says we can acquire knowledge on a need‐to‐know basis (...) by consulting portable, inner analogues of the world. This, however, leads to a dilemma. If the knowledge was stored in memory, it is difficult to see how we could have acquired it by consulting inner analogues, for it would seem that we knew it already. Moreover, if it was stored in memory, we lose the economies of storage that provide much of the rationale for external memory stores and hence for their inner analogues. If, on the other hand, the knowledge was not stored in memory, it is difficult to see how we could have acquired it by consulting inner analogues, for it was not there to be acquired. I propose a solution to this problem that turns on the concept of nonconceptual content, and I relate the solution to Stephen Kosslyn's (1994) architecture of perception and visual mental imagery. Viewed in a broader context, the solution shows that the world leaks into the mind, as well as mind leaking into the world. (shrink)

It is almost universally believed that some infinite regresses are vicious, and also almost universally believed that some are benign. In this paper I argue that regresses can be vicious for several different sorts of reasons. Furthermore, I claim that some intuitively vicious regresses do not suffer from any of the particular aetiologies that guarantee viciousness to regresses, but are nevertheless so on the basis of considerations of parsimony. The difference between some apparently benign and some apparently vicious regresses, then, (...) turns out to be a matter of a more general assessment of costs and benefits, making viciousness of regresses in some cases less of a local matter than is usually thought.

The article considers modern tendencies prevailing in the higher education system while training technical specialists nowadays. According to the authors, excluding the humanitarian courses from curriculum results in the complete dissolution of subjectivity in the impersonal world, which is deprived of “living” knowledge, that is, definite knowledge of a definite person. The application of such an approach is illustrated by the actor–network theory (ANT). While studying several works by ANT founders, it turned out to be clear that such an approach (...) eliminates any differences between natural and humanitarian, engineering, and philosophical knowledge. As a result, the net emerges consisting of numerous actants and which requires from every participant his “building‐in” a model with the functions being delegated to him in advance. The article concludes that an “alive” component is disappearing from the higher education nowadays when the main stress is being made on the knowledge acquired a priori, not a posteriori. (shrink)

This paper differentiates between two readings of Aristotle’s argument that unity and being are not “genē” (UBANG for short). On the first reading – proposed by commentators such as Ackrill, Shields, Loux, and McDaniel – UBANG entails the proposition that there are no features that characterise all beings insofar as they are, referred to by its contemporary proponents, including McDaniel, as ‘ontological pluralism’. On the second reading – proposed here – UBANG does not entail this proposition. The paper argues that (...) only on the second reading does Aristotle’s argument secure its conclusion, that the second reading is, in fact, the correct reading of UBANG, and that anyone who thinks that UBANG succeeds and entails ontological pluralism probably equivocates between two different senses of ‘genos’.

Nietzsche’s cardinal ideas - God is Dead, Übermensch and Eternal Return of the Same - are approached here from the perspective of psychiatric phenomenology rather than that of philosophy. A revised diagnosis of the philosopher’s mental illness as manic-depressive psychosis forms the premise for discussion. Nietzsche conceived the above thoughts in close proximity to his first manic psychotic episode, in the summer of 1881, while staying in Sils-Maria (Swiss Alps). It was the anniversary of his father’s death, and also of (...) the break-up of his friendship with Wagner, the most important relationship in his life. Despite having been acquainted with these ideas from reading philosophy and literature, Nietzsche created them de novo and imbued them with very personal meaning. Surprisingly, he never defined or explained his cardinal thoughts in his published writings, perhaps because rationally he could not. A resultant hermeneutic vacuum provoked an avalanche of interpretations in secondary literature. But could these ideas be delusions? A current definition of delusion is challenged, and an attempt is made at a limited comparison between delusion, scientific/philosophical doctrine and poetic creation. It is also argued that psychosis is a way of re-living trauma, and delusions can therefore be seen as a form of reasoning that helps to make sense of the world in a state of psychotic disintegration. Far from being false beliefs, delusions are a true expression of one’s innermost feelings and pain, albeit indirectly. The relationship between early parental loss and repeated trauma, psychosis and creativity is also explored. Indo-Pacific Journal of Phenomenology , Volume 8, Edition 1 May 2008. (shrink)

This paper focuses on the connection between meaning, the specific field of phenomenological philosophy, and mattering, the cornerstone of personal identity. Doing so requires that we take a stand on the scope and method of phenomenological philosophy itself. I will argue that while we can describe our lives in an “impersonal” way, such descriptions will necessarily omit what makes it the case that such lives can matter at all. This will require distinguishing between “personal” identity and “self” identity, an idea (...) well-established in the phenomenological literature – for instance, in Husserl’s distinction between the “transcendental ego” and the person -- but I will argue that self-identity is a normative achievement whose clarification requires a move into second-person phenomenology. The argument moves through three sections. First, I will discuss Aron Gurwitsch’s “non-egological” conception of consciousness and will explain the most important reason Husserl rejected this view in his transcendental phenomenology. Second, I will discuss some contemporary approaches to Husserl’s distinction between person and ego. Third, I will argue that these approaches testify to an ambiguity in Husserl’s account of being “true” to oneself that requires us to understand selfhood as having the structure Heidegger called care. The importance of this will be demonstrated phenomenologically in a critical examination of Paul Ricoeur’s ontology of selfhood, particularly his interpretation of the second-person phenomenology of conscience.

This article compares the concept of habitus, as formulated in the work of Mauss and Bourdieu, with the concept of habit, as formulated in the work of Merleau-Ponty and Dewey. The rationale for this, on one level, is to seek to clarify these concepts and any distinction that there may be between them – though the article notes the wide variety of uses of both concepts and suggests that these negate the possibility of any definitive definitions or contrasts. More centrally, (...) however, the purpose of the comparison is to draw out a number of important issues and debates which, it is argued, further work must address if the concepts of habit and habitus are to continue to prove useful and illuminating in social science.

The fallibility of deduction is the thesis that a thoughtful speaker-reasoner can wrongly believe that an inference is deductively valid. The author presents an argument to the effect that the fallibility of deduction is incompatible with the widespread view that deduction is epistemically unfruitful (the conclusion is contained in the premises, and the transition from premises to conclusion never extends knowledge). If the fallibility of deduction is a fact, the argument presented is a refutation of the doctrine of the unfruitfulness (...) of deduction. But its relevance goes further, because the argument reveals a connection between two different problems: a solution to the problem of fruitfulness (how can deductive inferences increase our knowledge?) is a starting point for a solution to the problem of fallibility (how can deductive inferences be wrong?). To solve the problem of fruitfulness, Michael Dummett proposed some general ideas concerning meaning and inference. Starting from these meaning-theoretical ideas, one can develop an explanation of the fallibility of deduction. The general explanatory strategy does not depend on the choice between a theory of meaning centered on truth, verification, inferential role, or on other key notions. (shrink)

In this paper I propose a naturalist account of the Buddhist epistemological discussion of svasaṃvitti ('self-awareness', 'self-cognition') following similar attempts in the domains of phenomenology and analytic epistemology. First, I examine the extent to which work in naturalized epistemology and phenomenology, particularly in the areas of perception and intentionality, could be profitably used in unpacking the implications of the Buddhist epistemological project. Second, I argue against a foundationalist reading of the causal account of perception offered by Dignāga and Dharmakīrti. Finally, (...) I argue that it is possible to read Dignāga's (and following him Dharmakīrti's) treatment of svasaṃvitti_ as offering something like a phenomenological account of embodied self-awareness. (shrink)

New nursing researchers are faced with a smorgasbord of competing methodologies. Sometimes, they are encouraged to adopt the research paradigms beloved of their senior colleagues. This is a problem if those paradigms are no longer of contemporary methodological relevance. The aim of this paper was to provide clarity about current research paradigms. It seeks to interrogate the continuing viability of positivism as a guiding paradigm for nursing research. It does this by critically analysing the methodological literature. Five major paradigms are (...) addressed: the positivist; the interpretivist/constructivist; the transformative; the realist; and the postpositivist. Acceptance of interpretivist, transformative or realist approaches necessarily entails wholesale rejection of positivism, while acceptance of postpositivism involves its partial rejection. Postpositivism has superseded positivism as the guiding paradigm of the scientific method. The incorporation in randomized controlled trials of postpositivist assumptions indicates that even on the methodological territory that it once claimed as its own, positivism has been rendered redundant as an appropriate paradigm for contemporary nursing research.

Prior Analytics by the Greek philosopher Aristotle (384 – 322 BCE) and Laws of Thought by the English mathematician George Boole (1815 – 1864) are the two most important surviving original logical works from before the advent of modern logic.

This comparison merits an article itself. Accordingly, this article does not discuss (...) many other historically and philosophically important aspects of Boole’s book, e.g. his confused attempt to apply differential calculus to logic, his misguided effort to make his system of ‘class logic’ serve as a kind of ‘truth-functional logic’, his now almost forgotten foray into probability theory, or his blindness to the fact that a truth-functional combination of equations that follows from a given truth-functional combination of equations need not follow truth-functionally. One of the main conclusions is that Boole’s contribution widened logic and changed its nature to such an extent that he fully deserves to share with Aristotle the status of being a founding figure in logic. By setting forth in clear and systematic fashion the basic methods for establishing validity and for establishing invalidity, Aristotle became the founder of logic as formal epistemology. By making the first unmistakable steps toward opening logic to the study of ‘laws of thought’—tautologies and laws such as excluded middle and non-contradiction—Boole became the founder of logic as formal ontology.

Philosophers of biology claim that function talk is consistent with naturalism. Yet recent work in biology places new pressure on this claim. An increasing number of biologists propose that the existence of functions depends on the organisation of systems. While systems are part of the domain studied by physics, they are capable of interacting with this domain through organising principles. This is to say that a full account of biological function requires teleology. Does naturalism preclude reference to teleological causes? Or (...) are organised systems precisely a naturalised form of teleology? In this paper I suggest that the biology of organised systems reveals several contradictions in the main philosophical conceptions of naturalism. To integrate organised systems with naturalism’s basic assumptions—that there is no theory-independent view for metaphysics, and that nature is intelligible—I propose an idealist solution. (shrink)
