Major schools of thought in the 20th century agreed in repudiating metaphysical speculation, but the agreement was superficial, for what they repudiated as “metaphysical” was often one another. Whitehead’s defense of speculative philosophy as “productive of important knowledge” singled him out for scorn from all sides at the same time that it enabled him to move beyond dogmatic standoffs . Employing the same method of speculative generalization that led to the most celebrated theoretical discoveries of the 20th century, quantum theory (...) and special relativity, Whitehead sought to resolve the conflict between objectifying, causal explanations of the world and its inhabitants and the “folk” attitudes defended and elaborated by humanistic psychologies and philosophies. The result was his theory of the “dipolar actual occasion” as the fundamental unit of existence. Recent work by leading scientists continues this effort to elaborate a nonreductive monism that accounts for both meaning and causation. (shrink)

La investigación ecológica a largo plazo (Long Term Ecological Research, LTER) maneja problemas que abarcan décadas o plazos más largos. El programa y su nombre formal comenzaron en Estados Unidos en 1980. Si bien los estudios y observaciones a largo plazo comenzaron tempranamente en 1400 y 1800 en Asia y Europa, respectivamente, el enfoque a largo plazo no se formalizó sino hasta el establecimiento de los programas de investigación ecológica de largo plazo en Estados Unidos. Estos programas han permitido experimentos (...) a nivel de ecosistemas y comparaciones entre sitios que condujeron a una mejor comprensión de la estructura y funcionamiento de la biosfera. El enfoque ecosistémico holístico de esta iniciativa permite también la incorporación de la dimensión humana en la ecología, y recientemente ha dado lugar al nuevo concepto de investigación socio-ecológica de largo plazo (LTSER). Hoy los programas de investigación socio-ecológica a largo plazo existen en por lo menos 32 países (esto es, los miembros de la Red Internacional de Investigación Ecológica a Largo Plazo o ILTER (International Long Term Ecological Research). Sin embargo, la consolidación de la red internacional dentro del paradigma de investigación socio-ecológica a largo plazo todavía requiere: (1) inclusión de algunas regiones remotas del mundo que aún están poco representadas, como el suroeste de América del Sur; (2) modificaciones en el tipo de investigación realizado, tales como la integración de las ciencias sociales y naturales con las humanidades y la ética, y (3) la incorporación de las conclusiones y resultados dentro de los procesos sociales y políticos. En este contexto, la naciente red de investigación socio-ecológica a largo plazo en Chile, que se extiende en el rango latitudinal más largo de bosque templado en el Hemisferio Sur, agrega una nueva región remota a las investigaciones ecológicas de largo plazo que había sido pasada por alto anteriormente. Además, la colaboración con la Universidad de North Texas y otros asociados internacionales ayuda a desarrollar un enfoque interdisciplinario para integrar las ciencias ecológicas y la filosofía ambiental, junto con los conocimientos ecológicos tradicionales, la educación informal y formal, la política, las humanidades, los procesos socio-políticos y la conservación biocultural.

I defend Kant’s definition of analyticity in terms of concept “containment”, which has engendered widespread scepticism. Kant deployed a clear, technical notion of containment based on ideas standard within traditional logic, notably genus/species hierarchies formed via logical division. Kant’s analytic/synthetic distinction thereby undermines the logico-metaphysical system of Christian Wolff, showing that the Wolffian paradigm lacks the expressive power even to represent essential knowledge, including elementary mathematics, and so cannot provide an adequate system of philosophy. The results clarify the extent to (...) which analyticity sensu Kant can illuminate the problem of a priori knowledge generally. (shrink)

Officially, for Kant, judgments are analytic iff the predicate is "contained in" the subject. I defend the containment definition against the common charge of obscurity, and argue that arithmetic cannot be analytic, in the resulting sense. My account deploys two traditional logical notions: logical division and concept hierarchies. Division separates a genus concept into exclusive, exhaustive species. Repeated divisions generate a hierarchy, in which lower species are derived from their genus, by adding differentia(e). Hierarchies afford a straightforward sense of containment: (...) genera are contained in the species formed from them. Kant's thesis then amounts to the claim that no concept hierarchy conforming to division rules can express truths like '7+5=12.' Kant is correct. Operation concepts ( ) bear two relations to number concepts: and are inputs, is output. To capture both relations, hierarchies must posit overlaps between concepts that violate the exclusion rule. Thus, such truths are synthetic. (shrink)

John Dewey (1859-1952) lived from the Civil War to the Cold War, a period of extraordinary social, economic, demographic, political and technological change. During his lifetime the United States changed from a rural to an urban society, from an agricultural to an industrial economy, from a regional to a world power. It emancipated its slaves, but subjected them to white supremacy. It absorbed millions of immigrants from Europe and Asia, but faced wrenching conflicts between capital and labor as they were (...) integrated into the urban industrial economy. It granted women the vote, but resisted their full integration into educational and economic institutions. As the face-to-face communal life of small villages and towns waned, it confronted the need to create new forms of community life capable of sustaining democracy on urban and national scales. Dewey believed that neither traditional moral norms nor traditional philosophical ethics were up to the task of coping with the problems raised by these dramatic transformations. Traditional morality was adapted to conditions that no longer existed. Hidebound and unreflective, it was incapable of changing so as to effectively address the problems raised by new circumstances. Traditional philosophical ethics sought to discover and justify fixed moral goals and principles by dogmatic methods. Its preoccupation with reducing the diverse sources of moral insight to a single fixed principle subordinated practical service to ordinary people to the futile search for certainty, stability, and simplicity. In practice, both traditional morality and philosophical ethics served the interests of elites at the expense of most people. To address the problems raised by social change, moral practice needed to be thoroughly reconstructed, so that it contained within itself the disposition to respond intelligently to new circumstances. Dewey saw his reconstruction of philosophical ethics as a means to effect this practical reconstruction. (shrink)

In this paper, I examine two versions of the so-called “hierarchical” approach to personal autonomy, based on the notion of “second-order desires”. My primary concern will be with the question of whether these approaches provide an adequate basis for understanding the dynamics of autonomy-ascription. I begin by distinguishing two versions of the hierarchical approach, each representing a different response to the oft-discussed “regress” objection. I then argue that both “structural hierarchicalism” (e.g., Frankfurt, Bratman) and “procedural hierarchicalism” (e.g., Dworkin, Christman, Mele) (...) have difficulties accommodating the dynamics of how the attribution of autonomy to persons is claimed, disputed, and resolved. Although they differ in details, both shortcomings can be traced to viewing autonomy as a metaphysical rather than a normative, practical matter. I conclude by suggesting that these difficulties underscore the advantages of a more constructivist and pragmatist. (shrink)

Little is known about study co-ordinators of gene therapy clinical trials. The purposes of this study were to: (1) describe characteristics of co-ordinators of gene therapy (transfer) clinical trials; (2) assess differences between nurse and non-nurse study co-ordinators; and (3) identify factors indicative of study co-ordinators' role preparation that could affect their role performance. This exploratory correlational study employed a convenience sample of 118 co-ordinators in the USA (55 participants; 47% response rate). The researcher created the Study Coordinator Role Preparedness (...) and Performance Survey to assess factors or correlates of study co-ordinator performance. Analysis of variance was used to compare nurses and non-nurses, and men versus women on their perceived preparedness, perceived quality of orientation, and satisfaction with educational opportunities. The findings contribute to knowledge by identifying present inadequacies in the training of study co-ordinators and in recognizing the need for more effective provision of orientation and continuing education with respect to ethical issues, knowledge of genetic science, and potential research integrity challenges.

the arguments in their favour are weak. Arguments based on reciprocity fail to explain why only means-tested public benefits should be subject to work requirements, and why unpaid dependant care work should not count as satisfying citizens’ obligations to reciprocate. Argu- ments based on promoting the work ethic misattribute recipients’ nonwork to deviant values, when their core problem is finding steady employment consistent with supporting a family and meeting dependant care responsibilities. Rigid work requirements impose unreasonable costs on some of (...) the poor. A welfare system based on a rebuttable presumption that recipients will work for pay, conjoined with more generous work supports, would promote justice better than either unconditional welfare or strict requirements [1].

One of the most foundational and continually contested questions in the cognitive sciences is the degree to which the functional organization of the brain can be understood as modular. In its classic formulation, a module was defined as a cognitive sub-system with nine specific properties; the classic module is, among other things, domain specific, encapsulated, and implemented in dedicated neural substrates. Most of the examinations—and especially the criticisms—of the modularity thesis have focused on these properties individually, for instance by finding (...) counterexamples in which otherwise good candidates for cognitive modules are shown to lack domain specificity or encapsulation. The current paper goes beyond the usual approach by asking what some of the broad architectural implications of the modularity thesis might be, and attempting to test for these. The evidence does not favor a modular architecture for the cortex. Moreover, the evidence suggests that best way to approach the understanding of cognition is not by analyzing and modelling different functional domains in isolation from the others, but rather by looking for points of overlap in their neural implementations, and exploiting these to guide the analysis and decomposition of the functions in question. This has significant implications for the question of how to approach the design and implementation of intelligent artifacts in general, and language-using robots in particular. (shrink)

Data from two national surveys of 4,000 faculty and doctoral students in chemistry, civil engineering, microbiology and sociology indicate that both faculty and students subscribe strongly to traditional norms but are more likely to see alternative counternorms enacted in their departments. They also show significant effects of departmental climate on normative orientations and suggest that many researchers express some degree of ambivalence about traditional norms.

This essay describes a general approach to building perturbation-tolerant autonomous systems, based on the conviction that artificial agents should be able to notice when something is amiss, assess the anomaly, and guide a solution into place. This basic strategy of self-guided learning is termed the metacognitive loop; it involves the system monitoring, reasoning about, and, when necessary, altering its own decision-making components. This paper (a) argues that equipping agents with a metacognitive loop can help to overcome the brittleness problem, (b) (...) details the metacognitive loop and its relation to our ongoing work on time-sensitive commonsense reasoning, (c) describes specific, implemented systems whose perturbation tolerance was improved by adding a metacognitive loop, and (d) outlines both short-term and long-term research agendas.

Maintaining adequate performance in dynamic and uncertain settings has been a perennial stumbling block for intelligent systems. Nevertheless, any system intended for real-world deployment must be able to accommodate unexpected change—that is, it must be perturbation tolerant. We have found that metacognitive monitoring and control—the ability of a system to self-monitor its own decision-making processes and ongoing performance, and to make targeted changes to its beliefs and action-determining components—can play an important role in helping intelligent systems cope with the perturbations (...) that are the inevitable result of real-world deployment. In this article we present the results of several experiments demonstrating the efficacy of metacognition in improving the perturbation tolerance of reinforcement learners, and discuss a general theory of metacognitive monitoring and control, in a form we call the metacognitive loop.

As part of the ongoing attempt to fully naturalize the concept of human being--and, more specifically, to re-center it around the notion of agency--this essay discusses an approach to defining the content of representations in terms ultimately derived from their central, evolved function of providing guidance for action. This 'guidance theory' of representation is discussed in the context of, and evaluated with respect to, two other biologically inspired theories of representation: Dan Lloyd's dialectical theory of representation and Ruth Millikan's biosemantics.

A key question in understanding microtubule dynamics is how GTP hydrolysis leads to catastrophe, the switch from slow growth to rapid shrinkage. We first provide a review of the experimental and modeling literature, and then present a new model of microtubule dynamics. We demonstrate that vectorial, random, and coupled hydrolysis mechanisms are not consistent with the dependence of catastrophe on tubulin concentration and show that, although single-protofilament models can explain many features of dynamics, they do not describe catastrophe as a (...) multistep process. Finally, we present a new combined (coupled plus random hydrolysis) multiple-protofilament model that is a simple, analytically solvable generalization of a single-protofilament model. This model accounts for the observed lifetimes of growing microtubules, the delay to catastrophe following dilution and describes catastrophe as a multistep process. (shrink)

Failure to recognize the "realistic" motivations for Putnam's commitment to internal realism has led to a widely shared misunderstanding of Putnam's arguments against metaphysical realism. Realist critics of these arguments frequently offer rebuttals that fail to confront his arguments. Simply put, Putnam's arguments --the brains in a vat argument as well as the model-theoretic argument -- are "reductios" that are intended to show that "metaphysical realism itself is not sufficiently realistic". If that claim can be substantiated then Putnam can go (...) on to argue that his own view is, by comparison, more realistic than metaphysical realism. (shrink)

The question of personal immortality is a central one for Gabriel Marcel. Early in his life he took part in parapsychological experiments which convincedhim that one could, rarely and with great difficulty, communicate with the dead. In a philosophical vein he argued that each self has an eternal dimension which isof eternal worth. This dimension is particularly manifest in self-sacrifice, where I find it meaningful to give my life for another and when I unconditionally commitment myself in love to another (...) self. Marcel also cites the experience of trust or hope, and the experience that life is not an absurd freak accident of nature destined for eternal extinction but rather possesses absolute meaning and value. Yet, none of the above experiences involves certitude; one remains free to accept or reject them and what they claim to involve. (shrink)

Rather surprisingly, T.H.Green's ideas on women and the family are as neglected today as they were immediately after his death in 1882, when his thought was first interpreted for a wider public by his colleagues and friends.1 Silence on such matters in the 1880s is not remarkable. It is odd, however, that it persists today, despite recent intense concern with the history of women and the family, including their place in political thought, and despite reviving philosophical interest in the British (...) Idealists and readiness to credit them with a significant impact on politics, education and social work. It has often been remarked that Green's political ideas have much in common superficially with those of John Stuart Mill, since their values and precepts are very similar, although the substructure of their thought is utterly different. Nevertheless it has altogether escaped notice that this is equally true of their ideas on women, marriage and family relationships. Today Mill's fabled feminism easily appears limited and imperceptive, and the priority he gave to the parliamentary vote strangely simplistic. Did Green show any greater realism and understanding? Did he practise as well as preach real equality between men and women, in private as well as public life? In short, what precisely was Green's position on 'the woman question'�? (shrink)
