Two characterizations are given of those structural consequence operations on a propositional language which can be defined via proofs from a finite number of polynomial rules.

An abstract logic A, C consists of a finitary algebraA and a closure systemC onA. C induces two other closure systems onA, C P andC I, by projective and inductive generation respectively. The various relations amongC, C P andC I are determined. The special case thatC is the standard equational closure system on monadic terms is studied in detail. The behavior of Boolean logics with respect to projective and inductive generation is determined.

A signed -equation is an expression of the form t t or t t, where t and t are -terms (for some ranked set ). We characterize those classes of -algebras which are models of a set of signed -equations. Further we consider the problem of finding a complete deductive system analogous to equational logic for the logical consequence operation restricted to signed equations.

Elizabeth Anscombe famously argued that "modern moral philosophy" centrally involved unsupported notions of obligation and culpability. Modern Moral Philosophy: From Grotius to Kant exhibits, for the first time, resources that modern moral philosophers had to respond to Anscombe's challenge, also enhancing our own philosophical grasp of morality and its foundations.

Creations of the Mind presents sixteen original essays by theorists from a wide variety of disciplines who have a shared interest in the nature of artifacts and their implications for the human mind. All the papers are written specially for this volume, and they cover a broad range of topics concerned with the metaphysics of artifacts, our concepts of artifacts and the categories that they represent, the emergence of an understanding of artifacts in infants' cognitive development, as well as the (...) evolution of artifacts and the use of tools by non-human animals. This volume will be a fascinating resource for philosophers, cognitive scientists, and psychologists, and the starting point for future research in the study of artifacts and their role in human understanding, development, and behaviour.Contributors: John R. Searle, Richard E. Grandy, Crawford L. Elder, Amie L. Thomasson, Jerrold Levinson, Barbara C. Malt, Steven A. Sloman, Dan Sperber, Hilary Kornblith, Paul Bloom, Bradford Z.

Theories of number concepts often suppose that the natural numbers are acquired as children learn to count and as they draw an induction based on their interpretation of the first few count words. In a bold critique of this general approach, Rips, Asmuth, Bloomfield [Rips, L., Asmuth, J. & Bloomfield, A.. Giving the boot to the bootstrap: How not to learn the natural numbers. Cognition, 101, B51–B60.] argue that such an inductive inference is consistent with a representational system that clearly (...) does not express the natural numbers and that possession of the natural numbers requires further principles that make the inductive inference superfluous. We argue that their critique is unsuccessful. Provided that children have access to a suitable initial system of representation, the sort of inductive inference that Rips et al. call into question can in fact facilitate the acquisition of larger integer concepts without the addition of any further principles.

If Saint Thomas Aquinas was a great theologian, it is in no small part because he was a great philosopher. And he was a great philosopher because he was a great metaphysician. In the twentieth century, metaphysics was not much in vogue, among either theologians or even philosophers; but now it is making a comeback, and once the contours of Thomas's metaphysical vision are glimpsed, it looks like anything but a museum piece. It only needs some dusting off. Many are (...) studying Thomas now for the answers that he might be able to give to current questions, but he is perhaps even more interesting for the questions that he can raise regarding current answers: about the physical world, about human life and knowledge, and (needless to say) about God. This book is aimed at helping those who are not experts in medieval thought to begin to enter into Thomas's philosophical point of view. Along the way, it brings out some aspects of his thought that are not often emphasized in the current literature, and it offers a reading of his teaching on the divine nature that goes rather against the drift of some prominent recent interpretations.

The result is nothing less than a fundamental reorientation of moral theory that enables it at last to account for morality's supreme authority--an account that ...

S. 39: "My project in this paper is to develop the initial distinction which I have drawn between recognition and appraisal respect into a more detailed and specific account of each. These accounts will not merely be of intrinsic interest. Ultimately I will use them to illuminate the puzzles with which this paper began and to understand the idea of self-respect." 42 " Thus, insofar as respect within such a pursuit will depend on an appraisal of the participant from the (...) perspective of whatever standards are held to be appropriate to the pursuit, such respect will depend on a judgement to which excellences of character are thought relevant. Note that exactly what aspect of the person's character is thought to be relevant in this instance is his recognition respect (or lack of it) for the standards of the pursuit." 44 "This attitude fails of being appraisal respect in that my having it toward the person is conditional on those traits being such as to make him server a particular purpose that I happen to have" 44 - 45 "To sum up: Appraisal respect is an attitude of positibe appraisal of a person either judged as a person or as engaged in some more specific pursuit. In the first case, the appropriate grounds are features of the person's character: dispositions to act for particular reasons or a higher-level disposition to act for the best reasons. In the second case, though features of character do not exhaust the appropriate grounds for appraisal respect, some such character traits will be relevant (recognition respect for the standards of a particular pursuit). Also, the other features which constitute the appoprate excellences of the pursuit must be related to traits of character in the way specified. In both cases, the positive appraisal of the person, and of his traits, must be categorical. It cannot depend on the fact that the person, because of his traits, serves an interest or purpose of one's own." 45 "To have recognition respect for someone as a person is to give appropriate weight to the fact that he or she is a person by being willing to constrain one's behaviour in ways required by that fact." 45 "This is rather different from having an attitude of appraisal respect for someone as a person. The latter is a positive appraisal oif an individual made with regard ti those features which are excellences of persons. As such, it is not owed to everone, for it may or may not be merited. When it is, what is merited is just the positive appraisal itself." 47 "Second, the only beings who are approriate objects of appraisal respect are those who are capable of acting for reasons and hence capable of conceiving of various facts as meriting more or less consideration in deliberation.".

For the last thirty years, the nation's mental health and social service systems have been under relentless assault, with dramatically rising costs and the fragmentation of service delivery rendering them incapable of ensuring the safety, security, and recovery of their clients. The resulting organizational trauma both mirrors and magnifies the trauma-related problems their clients seek relief from. Just as the lives of people exposed to chronic trauma and abuse become organized around the traumatic experience, so too have our social service (...) systems become organized around the recurrent stress of trying to do more under greater pressure: they become crisis-oriented, authoritarian, disempowered, and demoralized, often living in the present moment, haunted by the past, and unable to plan for the future.Complex interactions among traumatized clients, stressed staff, pressured organizations, and a social and economic climate that is often hostile to recovery efforts recreate the very experiences that have proven so toxic to clients in the first place. Healing is possible for these clients if they enter helping, protective environments, yet toxic stress has destroyed the sanctuary that our systems are designed to provide.This thoughtful, impassioned critique of business as usual begins to outline a vision for transforming our mental health and social service systems. Linking trauma theory to organizational function, Destroying Sanctuary provides a framework for creating truly trauma-informed services. The organizational change method that has become known as the Sanctuary Model lays the groundwork for establishing safe havens for individual and organizational recovery. The goals are practical: improve clinical outcomes, increase staff satisfaction and health, increase leadership competence, and develop a technology for creating and sustaining healthier systems. Only in this way can our mental health and social service systems become empowered to make a more effective contribution to the overall health of the nation.Destroying Sanctuary is a stirring call for reform and recovery, required reading for anyone concerned with removing the formidable barriers to mental health and social services, from clinicians and administrators to consumer advocates.

In these essays Stephen White examines the forms of psychological integration that give rise to self-knowable and self-conscious individuals who are responsible, concerned for the future, and capable of moral commitment. The essays cover a wide range of basic issues in philosophy of mind, metaphysics, moral psychology, and political philosophy, providing a coherent, sophisticated, and forcefully argued view of the nature of the self. Beginning with mental content and ending with Rawls and utilitarianism, each essay argues a distinctive line. (...) Together they are a unified and powerful philosophical position of considerable scope, one that provides a unique vision of the mind, consciousness, personhood, and morality. White argues that the unity of the self revealed in personal identity and moral responsibility is best understood in normative terms. Basic to such features of the self are the patterns of self-concern in which they are characteristically displayed and the internal justification that supports such concern. The treatment of intentionality and consciousness that grounds this account emphasizes privileged selfknowledge and practical rationality and their corresponding contributions to the unity of the self. A final source of unity emerges from the analysis of our fundamental commitments, an analysis that ensures a central place in moral theory for the notion of the self. (shrink)

What are ethical judgments about? And what is their relation to practice? How can ethical judgment aspire to objectivity? The past two decades have witnessed a resurgence of interest in metaethics, placing questions such as these about the nature and status of ethical judgment at the very center of contemporary moral philosophy. Moral Discourse and Practice: Some Philosophical Approaches is a unique anthology which collects important recent work, much of which is not easily available elsewhere, on core metaethical issues. Reinvigorated (...) naturalist moral realism and the various versions of moral realism, as well as irrealist, expressivist, and neo-Kantian constructivist theories are all represented in this fine collection, constituting a rich array of approaches to contemporary moral philosophy's most fundamental debates. An extensive introduction by Darwall, Gibbard, and Railton is also included, making this volume the most comprehensive and up-to-date work of its kind. Moral Discourse is ideally suited for use in courses in contemporary ethics, ethical theory, and metaethics. (shrink)

In this paper I distinguish three alternatives to the functionalist account of qualitative states such as pain. The physicalist-functionalist holds that (1) there could be subjects functionally equivalent to us whose mental states differed in their qualitative character from ours, (2) there could be subjects functionally equivalent to us whose mental states lacked qualitative character altogether and (3) there could not be subjects like us in all objective respects whose qualitative states differed from ours. The physicalist-functionalist holds (1) and (3) (...) but denies (2). The transcendentalist holds (1) and (2) and denies (3). I argue that both versions of physicalist-functionalism inherit the problem of property dualism which originally helped to motivate functionalist theories of mind. I also argue that neither version of physicalist-functionalism can distinguish in a principled way between those neurophysiological properties of a subject which are relevant to the qualitative character of that subject's mental states and those which are not. I conclude that the only alternative to a functionalist account of qualitative states is a transcendentalist account and that this alternative is not likely to appeal to the critics of functionalism.

This chapter defends the property dualism argument. The term “semantic premise” mentioned is used to refers to an assumption identified by Brian Loar that antiphysicalist arguments, such as the property dualism argument, tacitly assume that a statement of property identity that links conceptually independent concepts is true only if at least one concept picks out the property it refers to by connoting a contingent property of that property. It is argued that, the property that does the work in explaining the (...) possibility of a posteriori identities need not be a first-order property of the referent in question. On his view, the property dualism argument requires only a weaker semantic premise, which allows that the property in question be a higher order property. A refined version of the property dualism argument is formulated, which uses the weaker premise, and defends the argument against various objections. (shrink)

This book is a major work in the history of ethics, and provides the first study of early modern British philosophy in several decades. Professor Darwall discerns two distinct traditions feeding into the moral philosophy of the seventeenth and eighteenth centuries. On the one hand, there is the empirical, naturalist tradition, comprising Hobbes, Locke, Cumberland, Hutcheson, and Hume, which argues that obligation is the practical force that empirical discoveries acquire in the process of deliberation. On the other hand, there is (...) a group including Cudworth, Shaftesbury, Butler, and in some moments Locke, which views obligation as inconceivable without autonomy and which seeks to develop a theory of the will as self-determining.

We review the argument that latent image formation is a measurement in which the state vector collapses, requiring an enhanced noise parameter in objective reduction models. Tentative observation of a residual noise at this level, plus several experimental bounds, imply that the noise must be colored, and hence frame dependent and non-relativistic. Thus a relativistic objective reduction model, even if achievable in principle, would be incompatible with experiment; the best one can do is the non-relativistic CSL model. This negative conclusion (...) has a positive aspect, in that the non-relativistic CSL reduction model evades the argument leading to the Conway–Kochen “Free Will Theorem”. (shrink)
