The aim of this project was to explore the possibility of constructing a psychologic inference engine that might enhance introspective self-awareness by delivering inferences about a user based on what he said in interactive dialogues about his closest opposite-sex relation. To implement this aim, we developed a computer program (guru) with the capacity to simulate human conversation in colloquial natural language. The psychologic inferences offered represent the authors' simulations of their commonsense psychology responses to expected user-input expressions. The heuristics of (...) the natural language processor and its relation to output responses are described in enough detail for the operations of the implementation to be understood. Evaluation of this new cognitive agent presents, we hope, puzzles for artificial intelligence and cognitive science. (shrink)

The relationship of part to whole is one of the most fundamental there is; this is the first and only full-length study of this concept. This book shows that mereology, the formal theory of part and whole, is essential to ontology. Peter Simons surveys and criticizes previous theories, especially the standard extensional view, and proposes a more adequate account which encompasses both temporal and modal considerations in detail. 'Parts could easily be the standard book on mereology for the next (...) twenty or thirty years.' Timothy Williamson, Grazer Philosophische Studien. (shrink)

Frege's theory of real numbers has undeservedly received almost no attention, in part because what we have is only a fragment. Yet his theory is interesting for the light it throws on logicism, and it is quite different from standard modern approaches. Frege polemicizes vigorously against his contemporaries, sketches the main features of his own radical alternative, and begins the formal development. This paper summarizes and expounds what he has to say, and goes on to reconstruct the most important steps (...) which he is likely to have subsequently taken. The various difficulties facing his theory in this reconstruction are outlined, and some surprising consequences drawn about the nature of his logicism. (shrink)

A way of reading the Tractatus has been proposed which, according to its advocates, is importantly novel and essentially distinct from anything to be found in the work of such previously influential students of the book as Anscombe, Stenius, Hacker or Pears. The point of difference is differently described, but the currently most used description seems to be Goldfarb’s term ‘resolution’ – hence one speaks of ‘the resolute reading’. I’ll shortly ask what resolution is. For now, it is enough that (...) it aims to give full weight to the penultimate section of the Tractatus in which Wittgenstein declares his propositions to be nonsense, where giving full weight to that declaration involves not hearing it as allowing that those ‘nonsensical’ propositions might have another kind of ‘sense’. In that same section Wittgenstein explains that these nonsense propositions, while devoid of meaning, have a use: to make the kind of use of them that their author intends – and so to understand him – requires recognizing that they are nonsense; and through that recognition one ‘surmounts’ these propositions, and is led ‘to see the world aright’. So there is a point to all this nonsense. What point? (shrink)

0. My aims in this paper are largely expository: I am more interested in presenting the picture theory than deciding its truth. Even so, I hope that the arguments by which I develop the theory will do something to support it, since I believe that what I will present as Wittgenstein's view is indeed the truth. This is not an admission of insanity, though some things that have been thought intrinsic to the picture theory are things it would be insane (...) to believe. So clearly the view I will present, when compared to the most embracing interpretations, is a partial and selective one. It would be another kind of madness, one I am just as eagre to disown, to suppose that my own favoured selection is the only possible one. That is pretty well the last remark in this paper about other commentators. I trust my reticence entitles me to be presumed catholic until proven nonconformist. (shrink)

Wie kaum eine andere Materie in Deutschland ist der Verwaltungsrechtsschutz verfassungsrechtlich geprägt. In einer Rechtsordnung, in der das Diktum Fritz Werners vom Verwaltungsrecht als konkretisiertem Verfassungsrecht im Grundsatz nach wie vor gilt und als rechtsstaatlich-zivilisatorische Errungenschaft empfunden wird, muss dies für den Verwaltungsrechtsschutz – den gerichtlichen Rechtsschutz in Ansehung der öffentlichen Verwaltung – erst recht gelten. Das ist nicht nur das Produkt einer mehr oder weniger weit ausgreifenden Verfassungsexegese, sondern ein vielfältig abgesichertes Verfassungsgebot.

Philosophic inquiry into the mental states of elite athletes during skilled motor performance continues to grow. In contrast to the bulk of these works that focus almost exclusively on skillful performance, this paper examines athletic motor behavior from a point of inexactness – or even failure – in athletic performance. Utilizing the works of Michael Polanyi, who believed that both ideas of achievement and failure were equally necessary to understand the behavior of living things and their physical actions, I examine (...) the notion of failure as a framework to scrutinize the cognitive processes occurring during the development and performance of skilled motor behavior. After reviewing Polanyi’s conceptions of personal knowing to locate the source of inaccuracy in human activity, I present Polanyi’s distinction between two kinds of mistakes and apply each to inaccurate sport performance. I then suggest that mistakes in sport should be re-conceptualized beyond their current negative connotations. Instead, conceptions of mistakes should also include respect for ‘man’s most distinguished act’ – that being the production of knowledge. From this expanded perspective, the value of inexact motor performance can be found in addition to notions of uncertainty and skill development in what Polanyi calls ‘metaphysical implication of a groping for reality’. In some final thoughts, I will suggest future implications of the value of the inexact on broader sport issues. (shrink)

For most of the history of metaphysics, the subject has been dominated by the concept of substance. There is an everyday commonsense notion of substance which is perfectly harmless and which I shall defend against attempts to remove it or revise it away. But I deny that substance has to be construed as a primitive even in everyday terms. Borrowing Strawson’s distinction between descriptive and revisionary metaphysics, I press the legitimate claims of revisionary metaphysics and argue that there is no (...) place for a fundamental concept of substance within it, although aspects of the concept are likely to find their place therein.

Traditional views of rationality posit general-purpose decision mechanisms based on logic or optimization. The study of ecological rationality focuses on uncovering the “adaptive toolbox” of domain-specific simple heuristics that real, computationally bounded minds employ, and explaining how these heuristics produce accurate decisions by exploiting the structures of information in the environments in which they are applied. Knowing when and how people use particular heuristics can facilitate the shaping of environments to engender better decisions.

This book with an introduction by Witold Marciszewski, views the history of philosophy and logic from 1837 to 1939 from the perspective of the cradle of modern exact philosophy - Central Europe. In a series of case studies, it illuminates the developments in this region, most notably in Austria and Poland, examining thinkers such as Bolzano, Brentano, Meinong, Husserl, Twardowski, Lesniewski, and Tarski, as well as the logicians like Frege and Russell with whom they bore a close resemblance. The book (...) challenges established views about the history of philosophy and logic in Europe, and shows the vitality of the Central European tradition. (shrink)

In the fall of 1991, voters in Washington state were asked to consider a public initiative that sought to legalize physician-assisted death: Initiative 119. Drafted by Washington Citizens for Death with Dignity, the initiative was intended to amend the existing state natural death act in several ways:1) expand the definition of “terminal condition” to include patients in irrevers ible coma or persistent vegetative state;2) specifically name “artificial nutrition and hydration” as life-sustaining medical procedures that could be refused or withdrawn;3) legally (...) allow mentally competent patients with certifiably terminal conditions to request and receive “aid-in-dying” from their physician as a medical service.The first two proposed amendments were widely acknowledged as timely and appropriate; a coalition of medical, religious, and community organizations had been actively working on such additions for several years. It was the proposal to legalize “aid-in-dying,” however, that represented a radical shift in the conduct of physicians towards their patients and a dramatic shift in social policy. (shrink)

Shepard promotes the important view that evolution constructs cognitive mechanisms that work with internalized aspects of the structure of their environment. But what can this internalization mean? We contrast three views: Shepard's mirrors reflecting the world, Brunswik's lens inferring the world, and Simon 's scissors exploiting the world. We argue that Simon 's scissors metaphor is more appropriate for higher-order cognitive mechanisms and ask how far it can also be applied to perceptual tasks. [Barlow; Kubovy & Epstein; Shepard].

ABSTRACT:The link between firm corporate social performance (CSP) and executive compensation could be driven by a sorting effect (a firm’s CSP is related to the initial levels of compensation of newly hired executives), or by an incentive effect (incumbent executives are rewarded for past firm CSP). Existing empirical work focuses exclusively on the incentive effect. In contrast, in this paper we explore the sorting effect of firm CSP on the initial compensation of newly hired executives. In doing so, we develop (...) a novel theoretical approach based on an integration of stakeholder theory and human capital theory, suggesting a positive association between the initial compensation of executives and firm CSP strengths and concerns. It also suggests that the strength of this relationship varies between different executive roles (as a function of stakeholder-management responsibilities). We find support for this theoretical framework in a large sample of newly-hired executives employed by Standard & Poor 1500 firms. (shrink)

SummaryLeśniewski presented his logical systems in a way which conformed to his nominalism, so the question arises whether Leśniewski's logic can be given a natural formal semantics which, unlike current versions, avoids commitment to abstract entities. Building on hints in Wittgenstein's Tractatus, I develop the idea of a way of meaning which is the basis for what I call combinatorial semantics. I then consider whether this commits us to abstract objects or an intensional metalogic.

In the study of the arithmetic degrees the $\omega \text {-REA}$ sets play a role analogous to the role the r.e. degrees play in the study of the Turing degrees. However, much less is known about the arithmetic degrees and the role of the $\omega \text {-REA}$ sets in that structure than about the Turing degrees. Indeed, even basic questions such as the existence of an $\omega \text {-REA}$ set of minimal arithmetic degree are open. This paper makes progress on (...) this question by demonstrating that some promising approaches inspired by the analogy with the r.e. sets fail to show that no $\omega \text {-REA}$ set is arithmetically minimal. Finally, it constructs a $\prod ^0_{2}$ singleton of minimal arithmetic degree. Not only is this a result of considerable interest in its own right, constructions of $\prod ^0_{2}$ singletons often pave the way for constructions of $\omega \text {-REA}$ sets with similar properties. Along the way, a number of interesting results relating arithmetic reducibility and rates of growth are established. (shrink)

This paper continues a discussion that Adrian Moore and I have had about the place of idealism in Wittgenstein’s philosophy. While there are several unresolved issues in that discussion I want here to pursue only one; and, to minimize the risk of repetition, I will shift the primary focus of discussion from Wittgenstein’s earlier to his later thought. I will, though, have to say something first to identify the point I have in mind from the earlier discussion, and second to (...) indicate how the later issue corresponds to it. […] Moore and I share a view of Wittgenstein’s work as belonging to the Kantian, transcendental tradition; we are in agreement that the central requirement for a proper understanding of his thought is to make plain how it relates to the core ideas of that tradition, and in particular to transcendental idealism. But on just that issue we have disagreed. Suppressing niceties, and settling for what Adrian himself has called a “cartoon sketch,” Moore has held that in his early work Wittgenstein embraces transcendental idealism, while his later thought offers us ways of resisting it; whereas I have held exactly the reverse.

While theories of rationality and decision making typically adopt either a single-powertool perspective or a bag-of-tricks mentality, the research program of ecological rationality bridges these with a theoretically-driven account of when different heuristic decision mechanisms will work well. Here we described two ways to study how heuristics match their ecological setting: The bottom-up approach starts with psychologically plausible building blocks that are combined to create simple heuristics that fit specific environments. The top-down approach starts from the statistical problem facing the (...) organism and a set of principles, such as the bias– variance tradeoff, that can explain when and why heuristics work in uncertain environments, and then shows how effective heuristics can be built by biasing and simplifying more complex models. We conclude with challenges these approaches face in developing a psychologically realistic perspective on human rationality. (shrink)

Although Brentano generally regarded himself as at heart a metaphysician, his work then and subsequently has always been dominated by the Psychology. He is rightly celebrated as the person who reintroduced the Aristotelian-Scholastic notion of intentio back into the study of the mind. Brentano's inspiration was Aristotle's theory of perception in De anima, though his terminology of intentional inexistence was medieval. For the history of the work and its position in his output may I refer to my Introduction to the (...) reprinted English translation. Alongside Aristotle the work shows influences of Descartes, Comte and the British empiricists. The theory of intentionality presented in the Psychology is much less modern and less plausible than almost all recent commentary would have it, and was in any case not where Brentano's main interest lay. Intentionality simply served to demarcate mental phenomena from physical, in Book One, but the main aim was a classification of the mental, outlined in Book Two. Books Three to Five were to have dealt in detail with the three main classes of presentations, judgements and feelings, with the final book considering the metaphysics: mind-body and the immortality of the soul. Brentano's shifting views, recently documented in English with Benito Muller's translation of Descriptive Psychology, a work from the transitional 1890s, made the original plan obsolete. The role of an a priori, philosophical or descriptive psychology, methodologically prior to empirical-experimental genetic psychology, foreshadowed and influenced Husserl's notion of phenomenology, and Brentano's Comtean methodological epoche of desisting from controversial metaphysical statements in favour of an examination of the phenomena likewise presaged Husserl's more ponderous phenomenological reductions. Brentano's other work covers most areas of philosophy, notably ethics, where he upheld a form of a priori intuitionism much admired by G. E. Moore, the philosophy of religion, metaphysics, philosophy of language, deductive and inductive logic, and the history of philosophy. I shall mention just two areas. In his logic lectures from 1866 onwards (a compilation published 1956) Brentano rejected the subject-predicate analysis of simple judgements and proposed instead (for which he apparently secured written assent from Mill) that all judgements are logical compounds of positive and negative existential judgements. For example the universal judgement All men are mortal becomes the negative existential There are no immortal men. On this basis Brentano radically simplified the inference rules of deductive logic. While unlike de Morgan, Frege and others he does not go beyond logic's traditional scope by recognising relations, within its bounds his reformed-term logic is simple, elegant and easily teachable. Some of his ideas in logic influenced the young Husserl. Unfortunately Brentano took against mathematical logic, which he wrongly associated exclusively with Hamilton's confused doctrine of the quantification of the predicate. His inductive logic, which takes up by far the greater part of his logic lectures, remains unresearched to this day. (shrink)

The 1989 collapse of trade relations with the former socialist bloc plunged Cuba into an economic and food crisis. Cuban farmers, scientists, and planners have responded with alternative agricultural technology to make up for imported food and Green Revolution inputs that are no longer available. A review of Cuban experience to date with biological pest control practices shows that, on the one hand, significant progress has been made that may serve as a model for other countries, while, on the other (...) hand, there still remains a long way to go if Cuba is to create a truly sustainable agriculture. It is essential that we understand the Cuban case if we are to be concerned about ethical issues in biological control. The apparent ability of Cuba to overcome a food crisis without significant use of pesticides stretches our concept of the possible. It thus helps refute the most common argument – that we couldn't “feed the hungry” without pesticides – against taking the “ethical” position in real-world pest management policy debates. (shrink)

But logic as it stands, e.g. in Principia Mathematica, can quite well be applied to our ordinary propositions; e.g. from ‘All men are mortal’ and ‘Socrates is a man’ there follows according to this logic ‘Socrates is mortal’, which is obviously correct, even though I equally obviously do not know what structure is possessed by the thing Socrates or the property of mortality. Here they just function as simple objects.

Frege's obscure key concept of the unsaturatedness of functions is clarified with the help of the concepts of dependent and independent parts and foundation relations used by Husserl in describing the ontology of complex wholes. Sentential unity in Frege, Husserl and Wittgenstein: all have a similar explanation. As applied to linguistic expressions, the terms 'unsaturated' and 'incomplete' are ambiguous: they may mean the ontological property of Unselbständigkeit, inability to exist alone, or the property of being what categorial grammar calls a (...) functor. Separation of these two senses resolves a dispute between Dummett and Geach on the nature of predicates. (shrink)

The relationship of part to whole is one of the most fundamental there is, yet until now there has been no full-length study of this concept. This book shows that mereology, the formal theory of part and whole, is essential to ontology. Peter Simons surveys and criticizes previous theories, especially the standard extensional view, and proposes a more adequate account which encompasses both temporal and modal considerations in detail. This has far-reaching consequences for our understanding of such classical philosophical (...) concepts as identity, individual, class, substance and accident, matter, form, essence, dependence, and integral whole. It also enables the author to offer new solutions to long-standing problems surrounding these concepts, such as the Ship of Theseus Problem and the issue of mereological essentialism. The author shows by his use of formal techniques that classical philosophical problems are amenable to rigorous treatment, and the book represents a synthesis of issues and methods from the analytical tradition and from the older continental realist tradition of Brentano and the early Husserl.
