How can we understand human agency, and what does it mean to educate character? In this essay Klas Roth develops a Kantian notion, one that suggests we render ourselves efficacious and autonomous in education and elsewhere. This requires, among other things, that we are successful in bringing about the intended result through our actions and the means used, and that we act in accordance with and are motivated by the Categorical Imperative. It also requires that we are or strive (...) to become virtuous and that we engage in moral reflection, and, furthermore, that actions are done for the sake of duty, that is, out of respect for the moral law. We accomplish such aims by developing our predispositions, namely the technical, the pragmatic, and the moral predisposition in a society. The extent to which we achieve this, Roth contends, demonstrates what we are prepared to make of ourselves. (shrink)

Robert Roth, among the first few Catholics to write favorably, even if critically, about American pragmatism, presents here a creative piece of comparative philosophy in which he achieves a long-term goal of attempting a reconciliation between pragmatism and a classical spiritual and religious perspective. The title, Radical Pragmatism, is an adaptation of William James’s "radical empiricism." James had argues that the classical empiricists, Locke and Hume, did not go far enough in their account of experience. They missed some of (...) its most important aspects, namely connections and relations, and as a result they were left with discrete sense data and sense objects. (shrink)

My concern here is to motivate some theses in the philosophy of mind concerning the interpersonal character of intentions. I will do so by investigating aspects of shared agency. The main point will be that when acting together with others one must be able to act directly on the intention of another or others in a way that is relevantly similar to the manner in which an agent acts on his or her own intentions. What exactly this means will become (...) clearer once we understand what it is to act directly on one’s own intentions. But I take it to be a fundamental assumption of the prevailing individualism of the theory of action— one at the core of its conception of the separateness of individuals— that one person cannot act directly on another’s intention. I agree that there is an important way in which we are or can be separate and autonomous thinkers and agents. But the way the individualist tries to capture this separateness is misguided. (shrink)

The purpose of this paper is to argue that the tactic of granting a fetus the legal status of a person will not, contrary to the expectations of opponents of abortion, provide grounds for a general prohibition on abortions. I begin by examining two arguments, one moral (J. J. Thomson's A Defense of Abortion) and the other legal (D. Regan's Rewriting Roe v. Wade), which grant the assumption that a fetus is a person and yet argue to the conclusion that (...) abortion is permissible. However, both Thomson and Regan rely on the so-called bad samaritan principle. This principle states that a person has a right to refuse to give aid. Their reliance on this principle creates problems, both in the moral and the legal contexts, since the bad samaritan principle is intended to apply to passive refusals to aid; abortion, however, does not look like any such passive denial of aid, and so it does not seem like the sort of action covered by the bad samaritan principle. In defense of the positions outlined by Thomson and Regan, I argue that the apparent asymmetry between abortion and the usual type of case covered by the bad samaritan principle is only apparent and not a genuine problem for their analyses. I conclude with a defense of the morality of the bad samaritan principle. (shrink)

In this paper, we introduce a novel difficulty for teleosemantics, viz., its inability to account for what we call unexploited content—content a representation has, but which the system that harbors it is currently unable to exploit. In section two, we give a characterization of teleosemantics. Since our critique does not depend on any special details that distinguish the variations in the literature, the characterization is broad, brief and abstract. In section three, we explain what we mean by unexploited content, and (...) argue that any theory of content adequate to ground representationalist theories in cognitive science must allow for it.1 In section four, we show that teleosemantic theories of the sort we identify in section two cannot accommodate unexploited content, and are therefore unacceptable if intended as attempts to ground representationalist cognitive science. Finally, in section five, we speculate that the existence and importance of unexploited content has likely been obscured by a failure to distinguish representation from indication, and by a tendency to think of representation as reference.

The intentions of others often enter into your practical reasoning, even when you’re acting on your own. Given all the agents around you, you’ll come to grief if what they’re up to is never a consideration in what you decide to do and how you do it. There are occasions, however, when the intentions of another (or others) figure in your practical reasoning in a particularly intimate and decisive fashion. I will speak of there being on such occasions a practical (...) intersubjectivity of intentions holding between you and the other individual(s). I will try to identify this practical intersubjectivity, and to take some preliminary steps toward giving a philosophical account of it. Occasions of practical intersubjectivity are usually those where individuals share agency, or do things jointly, such as when they walk together, kiss, or paint a house together. I will not assume that all instances of practical intersubjectivity are instances of shared agency. But the converse is true: any instance of shared agency involves a practical intersubjectivity holding between the participants. An account of shared agency (or related notions like shared activity, joint action, etc.) is inadequate if it fails to handle practical intersubjectivity. The paper is structured as follows. In section 1, I present an example to illustrate this idea of practical intersubjectivity, at least as it appears in the context of shared agency. Practical intersubjectivity is a normative phenomenon, and it is on this basis that in section 2 I distinguish it from the mere coordination of intentions some have recognized as essential for shared activity. The task of section 3 is to show how practical intersubjectivity cannot be adequately described in terms of ordinary intentions familiar from the study of individual agency. Such approaches fail to handle the rational dynamics of intention revision when practical.. (shrink)

For the better part of the 20th century, expositions of issues regarding historical explanation followed a predictable format, one that took as given the nonequivalence of explanations in history and philosophical models of scientific explanation. Ironically, at the present time, the philosophical point of note concerns how the notion of science has itself changed. Debates about explanation in turn need to adapt to this. This prompts the question of whether anything now still makes plausible the thought that history must make (...) some forced choice with regard to the type of science it is and an associated explanatory form. The discussion that follows sketches the alternative forms of explanation between which historians were to pick, and indicates why each proves unsatisfactory. Examination of these issues allows identification of a conception of historical explanation that does not require the metaphysical and epistemological assumptions that engender previous dichotomous characterizations.

The current debate over systematicity concerns the formal conditions a scheme of mental representation must satisfy in order to explain the systematicity of thought.1 The systematicity of thought is assumed to be a pervasive property of minds, and can be characterized (roughly) as follows: anyone who can think T can think systematic variants of T, where the systematic variants of T are found by permuting T’s constituents. So, for example, it is an alleged fact that anyone who can think the (...) thought that John loves Mary can think the thought that Mary loves John, where the latter thought is a systematic variant of the former.

Recently, connectionist models have been developed that seem to exhibit structuresensitive cognitive capacities without executing a program. This paper examines one such model and argues that it does execute a program. The argument proceeds by showing that what is essential to running a program is preserving the functional structure of the program. It has generally been assumed that this can only be done by systems possessing a certain temporalcausal organization. However, counterfactualpreserving functional architecture can be instantiated in other ways, for (...) example geometrically, which are realizable by connectionist networks. (shrink)

Davidson held that the explanation of action in terms of reasons was a form of causal explanation. He challenged anti-causalists to identify a non-causal relation underlying reasons-explanation which could distinguish between merely having a reason and that reason being the one for which one acts. George Wilson attempts to meet Davidson's challenge, but the relation he identifies can serve only in explanations of general facts, whereas reasons explanation is often of particular acts. This suggests that the relation underlying reasons explanation (...) is not only causal, but singular as well. A further proposal, extracted from Fred Dretske's views, characterizes this singular causal relation in terms of non-mental triggers. But this suggestion underestimates the explanatory role of the environment at the time of action, and shares with Wilson's proposal the inability to account for the rationalization of particular acts. A situational environmentalist conception of reasons explanation, however, does not face these difficulties. (shrink)

An appreciation of Hume's psychology of object identity allows us to recognize certain tensions in his discussion of the origin of our belief in personal identity-tensions which have gone largely unnoticed in the secondary literature. This will serve to provide a new solution to the problem of explaining why Hume finds that discussion of personal identity so problematic when he famously disavows it in the Appendix to the Treatise. It turns out that the two psychological mechanisms which respectively generate the (...) ideas of object and of personal identity are mutually incompatible. It is this sort of conflict within Hume's introspective or subjectivist psychology which is the source of his worry. (shrink)

What makes for a good explanation of a person’s actions? Their reasons, or soa natural reply goes. But how do reasons function as part of explanations, that is, within an account of the causes of action? Here philosophers divide concerning the logical relation in which reasons stand to actions. For, tradition holds, reasons evaluatively characterized must be causally inert, inasmuch as the normative features cannot be found in any account of the empirical/descriptive. To countenance reasons as causes thus seems to (...) imply some degree of normative involvement in causal explanation. Mark Risjord opts for full normative involvement while David Henderson insistently denies a role to norms in explanation. Stueber occupies an intermediate position here. I question just whether there exists some "special" problem regarding norms, at least in the form which, I take it, all three of the authors I discuss assume there to be one. Key Words: reasons • causes • norms • rules • explanation. (shrink)

This paper surveys the parallel fates of the notion of the empirical in philosophy of science in the 20th century and the notion of experience as evidence in one important line of debate in historiography/philosophy of history. The focus concerns the presumably crucial role some notion of the empirical plays in the assessment of knowledge claims. The significance of 'the empirical' disappears on the assumption that theories either determine what counts as experience or explain away any apparently discordant evidence. One (...) consequence of this has been the suggestion that the analysis of meaning somehow replaces or supplants that played by evidence qua fact. This dispute impacts in parallel ways the turf wars between philosophers of science and practitioners of science studies as well as disputes in historiography between literary theorists and those not so kindly disposed. The parallels suggest why historiographic debate has stalled for three decades. (shrink)

Three theories contend as explanations of perpetrator behavior in the Holocaust as well as other cases of genocide: structural, intentional, and situational. Structural explanations emphasize the sense in which no single individual or choice accounts for the course of events. In opposition, intentional/cutltural accounts insist upon the genocides as intended outcomes, for how can one explain situations in which people ‘step up’ and repeatedly kill defenseless others in large numbers over sustained periods of time as anything other than a choice? (...) Situational explanations offer a type of behavioral account; this is how people act in certain environments. Critical to the situational account as I discuss it is the ‘Asch paradigm’, i.e. experimentally attested conditions for eliciting conformity of behavior regardlesss of available evidence of prior beliefs. In what follows, I defend what I term above a version of situational explanations of perpetrator behavior. Moreover, I maintain that the factors that explain provide an understanding as well. While not committed to the complete irrelevance or exclusion of cultural or structural factors, nonetheless situational analyses can account both for what happened and why. A cardinal virtue of this version of situational explanations consists in showing how shallow the problem of under- standing turns out to be for such cases. (shrink)

Riddles of induction – old or new, Hume’s or Goodman’s – pose unanswered challenges to assumptions that experiences logically legitimate expectations or classifications. The challenges apply both to folk beliefs and to scientific ones. In particular, Goodman’s ‘new riddle’ famously confounds efforts to specify how additional experiences confirm the rightness of currently preferred ways of organizing objects, i.e. our favored theories of what kinds there are.1 His riddle serves to emphasize that neither logic nor experience certifies accepted groupings of objects (...) into kinds.2 Hacking strongly endorses Goodman’s riddle and its chief consequences – nature does not dictate any organizing scheme to us, and different schemes need have no connection to one another.

We argue that atomistic learning?learning that requires training only on a novel item to be learned?is problematic for networks in which every weight is available for change in every learning situation. This is potentially significant because atomistic learning appears to be commonplace in humans and most non-human animals. We briefly review various proposed fixes, concluding that the most promising strategy to date involves training on pseudo-patterns along with novel items, a form of learning that is not strictly atomistic, but which (...) looks very much like it ?from the outside?

Although Weber's path-breaking work on the Protestant Ethic and the Spirit of Capitalism has received much attention ever since it first appeared in 1904-5, recent research has uncovered important new aspects. This volume, the result of an international, interdisciplinary effort, throws new light on the intellectual and cultural background of Weber's work, debates recent criticism of Weber's thesis, and confronts new historical insight on the seventeenth century with Weber's interpretation. Revisiting Weber's thesis serves to deepen our understanding of Weber as (...) much as it will stimulate further research. (shrink)

This article explores and attempts to resolve some issues that arise when psychoanalytic explanations are construed as a type of historical or narrative explanation. The chief problem is this: If one rejects the claim of narratives to verisimilitude, this appears to divorce the notion of explanation from that of truth. The author examines, in particular, Donald Spence's attempt to deal with the relation of narrative explanations and truth. In his critique of Spence's distinction between narrative truth and historical truth, the (...) author develops some suggestions regarding the role of truth in narrative explanations. (shrink)

It has been commonplace in epistemology since its inception to idealize away from computational resource constraints, i.e., from the constraints of time and memory. One thought is that a kind of ideal rationality can be specified that ignores the constraints imposed by limited time and memory, and that actual cognitive performance can be seen as an interaction between the norms of ideal rationality and the practicalities of time and memory limitations. But a cornerstone of naturalistic epistemology is that normative assessment (...) is constrained by capacities: you cannot require someone to do something they cannot or, as it is usually put, ought implies can. This much we take to be uncontroversial. We argue that differences in architectures, goals and resources imply substantial differences in capacity, and that some of these differences are ineliminable. It follows that some differences in goals and architectural and computational resources matter at the normative level: they constrain what principles of normative epistemology can be used to describe and prescribe their behavior. As a result, we can expect there to be important epistemic differences between the way brains, individuals, and science work. (shrink)

A suggestion famously made by Peter Winch and carried through to present discussions holds that what constitutes the social as a kind consists of something shared – rules or practices commonly learned, internalized, or otherwise acquired by all members belonging to a society. This essays argues against the explanatory efficacy of appeals to this shared something as constitutive of a social kind by examining a violation of social norms or rules, viz., mistakes. I argue that an asymmetric relation exists between (...) the notion of mistakes and that of the social. In particular, mistakes do not presuppose a concept of the social, but the concept of the social requires prior specification of a category of mistakes. But no such prior specification proves possible. The very notion of a mistake is so inchoate that it makes it impossible to provide the kind of regimentation required for a rule-governed domain. Thus, there may be recognized mistakes even in the absence of a unified system or common knowledge of norms.Later writers attempt to avoid Winch's over-strong assumption that something shared and internal constitutes the social but cannot. Extending recent work by Stephen Turner, I argue that ``the social'' is not a domain that is susceptible to lawlike treatment, but rather a heterogeneous, motley collection. For absent the assumption of a shared something, no social object exists to be explained. So, I conclude, we have at present no clear way of marking out the social as a coherent or unified domain of inquiry. (shrink)

Living systems are characterized as self-generating and self-maintaining systems. This type of characterization allows integration of a wide variety of detailed knowledge in biology.The paper clarifies general notions such as processes, systems, and interactions. Basic properties of self-generating systems, i.e. systems which produce their own parts and hence themselves, are discussed and exemplified. This makes possible a clear distinction between living beings and ordinary machines. Stronger conditions are summarized under the concept of self-maintenance as an almost unique character of living (...) systems. Finally, we discuss the far-reaching consequences that the principles of self-generation and self-maintenance have for the organization, structure, function, and evolution of single- and multi-cellular organisms.

Since Durkheim ([1912] 1965), the concept of ritual has held a privileged position in studies of social life because investigators recurrently have treated it as a source of insight into core issues of human sociality, such as the maintenance of social order. Consequently, studies of ritual have typically focused on rituals' function(s), and, specifically, whether ritual begets social integration or fragmentation. In this frame, students of ritual have tended to ignore other, equally fundamental issues, including (1) how actions, or courses (...) of action, constitute a ritual, and (2) whether ritual is best understood as an aspect of all social action or a specific type of it. Drawing on Durkheim's overlooked contemporary, Van Gennep ([1908] 1960), I argue that analyses of ritual must describe how participants enact an occasion as ritual through distinctive activities and sequences of these. Analysts of ritual must attempt to ground the relevance of their descriptions in the participants' demonstrable orientations, an undertaking with more general implications for the study of social action.

In this article, we propose that gestures play an important role in the connection between sensorimotor experience and language. Gestures may be the link between bodily experience and verbal expression that advocates of embodied cognition have postulated. In a developmental sequence of communicative action, gestures, which are initially similar to action sequences, substantially shorten and represent actions in metonymic form. In another process, action sequences are based on kinesthetic schemata that themselves find their metaphoric expression in language. Again, gestures enact (...) kinesthetic schemata that are correlated with verbal expressions. Examples from a large database are used to illustrate the various processes by means of which language arises when students conduct school science investigations. (shrink)

Organisms are self-producing and self-maintaining, or autopoietic systems. Therefore, the course of evolution and adaptation of an organism is strongly determined by its own internal properties, whatever role external selection may play. The internal properties may either act as constraints that preclude certain changes or they open new pathways: the organism canalizes its own evolution. As an example the evolution of feeding mechanisms in salamanders, especially in the lungless salamanders of the family Plethodontidae, is discussed. In this family a large (...) variety of different feeding mechanisms is found. The authors reconstruct this evolutionary process as a series of bifurcation points of either constraints or opportunities forming a sequence of preconditions for the formation of a high-speed projectile tongue characteristic of tropical salamanders. Furthermore, it is shown how parallel evolution of seemingly unrelated domains within an organism such as respiratory physiology, life history biology and pattern of ontogeny has rather direct relevance to the feeding biology, thus demonstrating that organisms always evolve as wholes.

Standard practices in experimental economics arise for different reasons. The “no deception” rule comes from a cost-benefit tradeoff; other practices have to do with the uses to which economists put experiments. Because experiments are part of scientific conversations that mostly go on within disciplines, differences in standard practices between disciplines are likely to persist.

The processing of information within the retino-tectal visual system of amphibians is decomposed into five major operational stages, three of them taking place in the retina and two in the optic tectum. The stages in the retina involve (i) a spatially local high-pass filtering in connection to the perception of moving objects, (ii) separation of the receptor activity into ON- and OFF-channels regarding the distinction of objects on both light and dark backgrounds, (iii) spatial integration via near excitation and far-reaching (...) inhibition. Variation of the spatial range of excitation and inhibition allows to account for typical activities observed in a variety of classes of retina ganglion cells.Mathematical description of the operations in the tectum opticum include (i) spatial summation of retinal output (mainly of class-2 and class-3 retina ganglion cells), and (ii) direct or indirect lateral inhibition between tectal cells. In the computer simulation, first the output of the mathematical retina model is computed which, then, is used as the input to the tectum model. The full spatio-temporal dynamics is taken into account. (shrink)

This book is psychiatry's reply to the diverse group of antipsychiatrists, including Laing, Foucault, Goffman, Szasz and Bassaglia, that has made fashionable the view that mental illness is merely socially deviant behaviour and that psychiatrists are agents of the capitalist society seeking to repress such behaviour. It establishes, by the use of evidence from historical and transcultural studies, that mental illness has been recognised in all cultures since the beginning of history and goes on to explore the philosophical and medical (...) basis for psychiatry's diagnosis and treatment of mental illness. Finally, it tackles two issues where psychiatry has recently been seen as at odds with the values prevailing in society: involuntary hospitalization and the insanity defence. The Reality of Mental Illness does not pretend to offer simple answers to the complex problems it discusses, but will leave the reader with a much greater understanding of psychiatry's aims, practices and problems.

In a career of over seventy years, Kenneth Burke has produced a body of challenging and fascinating theoretical work. This work has had a bigger reputation than it has had a readership. Burke has been hailed not only as a strong precursor of the work of Fredric Jameson, Frank Lentriccia, and others, but also as a powerful original thinker whose writings have yet to be grappled with. Kenneth Burke: Rhetoric and Ideology is a lucid and accessible introduction to (...) a major twentieth-century thinker whose ideas have influenced fields as diverse as literary criticism, philosophy, linguistics, politics, anthropology and sociology. Stephen Bygrade explores the content of Burke's vast output, theorizing the cultural and philosophical implications of his work. Bygrave's rigorous arguments focus around Burke's preoccupation with the relationship between language, ideology, and action. This book traces Burke's "rhetorical strategies" and argues that they form a bridge between "action" and "symbolic action." By considering Burke as a reader and writer of narratives and systems, Bygrade examines the inadequacies of earlier readings of Burke and enfolds his thought within current debates on Anglo-American cultural theory. By reinstating Burke into contemporary cultural theory, this book offers a way of reading his ideas, as well as introducing students of literature and cultural studies to the range of ideas found in his work.

Postmodernism charges that sociological methods project ways of thinking and being from the past onto the future, and that sociological forms of presentation are rhetorical defenses of ideologies. Postmodernism contends that sociological theory presents reified constructs no more based in reality than are fictional accounts. Kenneth Burke's logology predates and adequately addresses postmodernism's valid charges against sociology. At the same time, logology avoids the idealistic tendencies and ethical pitfalls of radical forms of postmodernist deconstruction, which acknowledge neither pretextual and (...) extratextual worlds nor the ways in which experience is embodied. While not fully articulated. Burke's logology gives primacy to an embodied, social world prior to text (Body-as-World). Sociology can strengthen both its theoretical arsenal and its response to postmodernism by reacknowledging and reclaiming Burke's logology. (shrink)

In his discussion of results which I (with Michael Hayward) recently reported in this journal, Kenneth Aizawa takes issue with two of our conclusions, which are: (a) that our connectionist model provides a basis for explaining systematicity within the realm of sentence comprehension, and subject to a limited range of syntax (b) that the model does not employ structure-sensitive processing, and that this is clearly true in the early stages of the network''s training. Ultimately, Aizawa rejects both (a) and (...) (b) for reasons which I think are ill-founded. In what follows, I offer a defense of our position. In particular, I argue (1) that Aizawa adopts a standard of explanation that many accepted scientific explanations could not meet, and (2) that Aizawa misconstrues the relevant meaning of structure-sensitive process.

Roth claims that in constituting the sorts of events they want to connect, historians conceive matters that may not correlate with any inventory of elements eligible for admission by natural science. Given “the liabilities incurred by the very questions historians choose to ask,” the question of historical explanation is a problem of our own making. “Previous challenges to the epistemic legitimacy of historical explanations lose their point,” for no one can ask what kind of science or what kind of (...) explanation history is, since it is none! This is, unsurprisingly, an unacceptable outcome for me. A case can be made for intersubjective assertability of a historical interpretation and the contestation of it - however tentatively, fallibly, partially - without a complete collapse into the aesthetics of form or the politics of the formulator. The task of the philosophy of history is to work out the reconciliation of the performative with the constative in historical writing and in historical appraisal. (shrink)

Kenneth Burke, arguably the most important American literary theorist of the twentieth century, helped define the theoretical terrain for contemporary literary and cultural studies. His perspectives were literary and linguistic, but his influences ranged across history, philosophy, and the social sciences. In this important and original study Robert Wess traces the trajectory of Burke's long career and situates his work in relation to postmodernity. His study is both an examination of contemporary theories of rhetoric, ideology, and the subject, and (...) an explanation of why Burke failed to complete his Motives trilogy. Burke's own critique of the 'isolated unique individual' led him to question the possibility of unique individuation, a strategy which anticipated important elements of postmodern concepts of subjectivity. Robert Wess's study is both a timely and judicious exposition of Burke's massive oeuvre, and a crucial intervention in current debates on rhetoric and human agency. (shrink)

A previously unexplored method, combining logical and mathematical elements, is shown to yield substantial numerical improvements in the area of Diophantine approximations. Kreisel illustrated the method abstractly by noting that effective bounds on the number of elements are ensured if Herbrand terms from ineffective proofs of Σ 2 -finiteness theorems satisfy certain simple growth conditions. Here several efficient growth conditions for the same purpose are presented that are actually satisfied in practice, in particular, by the proofs of Roth's theorem (...) due to Roth himself and to Esnault and Viehweg. The analysis of the former yields an exponential bound of order exp(70ε -2 d 2 ) in place of exp(285ε -2 d 2 ) given by Davenport and Roth in 1955, where α is (real) algebraic of degree d ≥ 2 and $|\alpha - pq^{-1}| . (Thus the new bound is less than the fourth root of the old one.) The new bounds extracted from the other proof are polynomial of low degree (in ε -1 and log d).
