On the traditional deontic framework, what is required (what morality demands) and what is optimal (what morality recommends) can't be distinguished and hence they can't both be represented. Although the morally optional can be represented, the supererogatory (exceeding morality's demands), one of its proper subclasses, cannot be. The morally indifferent, another proper subclass of the optional-one obviously disjoint from the supererogatory-is also not representable. Ditto for the permissibly suboptimal and the morally significant. Finally, the minimum that morality allows finds no (...) place in the traditional scheme. With a focus on the question, What would constitute a hospitable logical neighborhood for the concept of supererogation?, I present and motivate an enriched logical and semantic framework for representing all these concepts of common sense morality.

This is a review of John Horty's book, _Agency and Deontic Logic_, OUP 2000.

Overview of fundamental work in deontic logic.

There is little work of a systematic nature in ethical theory or deontic logic on aretaic notions such as praiseworthiness and blameworthiness, despite their centrality to common-sense morality. Without more work, there is little hope of filling the even larger gap of attempting to develop frameworks integrating such aretaic concepts with deontic concepts of common-sense morality, such as what is obligatory, permissible, impermissible, or supererogatory. It is also clear in the case of aretaic concepts that agency is central to such (...) appraisal, so some agential notions must be integrated with aretaic concepts as well. The current paper takes the first step in a larger project aimed at the closure of these gaps. Here I sketch a simple framework for the aretaic appraisal of an agent's performance, layered on top of a simple framework for agency and predetermination. In Part I, I develop the framework for agency, ability, and inevitability, combining elements of work by Brown, Elgesem, Carmo, Santos, and Jones. In Part II, drawing on work by Chisholm and Sosa on intrinsic preferability, I sketch and explore a framework for defining aretaic superiority, praiseworthiness, blameworthiness, neutrality, and indifference, etc., retaining proper links to agency.

The standard analysis of supererogation is that of optional actions that are praiseworthy to perform, but not blameworthy to skip. Widespread assumptions are that action beyond the call is at least necessarily equivalent to supererogation ("The Equivalence") and that forgoing certain agent-favoring prerogatives entails supererogation (“The Corollary”). I argue that the classical conception of supererogation is not reconcilable with the Equivalence or the Corollary, and that the classical analysis of supererogation is seriously defective. I sketch an enriched conceptual scheme, “Doing (...) Well Enough (DWE)”, that allows for distinct analyses of action beyond the call and supererogation, among other often neglected fundamental moral notions. Parallels and asymmetries with suberogation are briefly explored. Apparently, DWE’s core act-evaluative notions are more fundamental than the agent-evaluative ones of supererogation/suberogation.

Appears to give the first model-theoretic account of both "must" and "ought" (without conflating them with one another). Some key pre-theoretic semantic and pragmatic phenomena that support a negative answer to the main title question are identified and a conclusion of some significance is drawn: a pervasive bipartisan presupposition of twentieth century ethical theory and deontic logic is false. Next, an intuitive model-theoretic framework for "must" and "ought" is hypothesized. It is then shown how this hypothesis helps to explain and (...) predict all the pre-theoretic phenomena previously observed. Next, I show that the framework hypothesized possesses additional expressive and explanatory power (e.g. derivatively predicting the existence of supererogatory and permissibly suboptimal alternatives), thus adding further confirmation that it is on the right track. (shrink)

In the latter half of this century, there have been two mostly separate threads within ethical theory, one on 'superogation', one on 'common-sense morality'. I bring these threads together by systematically reflecting on doing more than one has to do. A rich and coherent set of concepts at the core of common-sense morality is identified, along with various logical connections between these core concepts. Various issues in common-sense morality emerge naturally, as does a demonstrably productive definition of doing more than (...) one has to do. I then present an interpreted model-theoretic framework with the expressive power to generate truth-conditions for the core concepts, and the explanatory power to predict and explain the independently motivated logical connections between these concepts. The framework also has a certain heuristic power for 'discovering' substantive ethical theories that can derivatively generate the model-theoretic framework for the core concepts. Two theories discussed are expansions of traditional theories; two others, each giving pride of place to justice, are devised to resonate with more recent concerns. Methodologically, it is hoped that the approach within might suggest the possibility of bridging another gap: that between formal and informal studies of moral notions. (shrink)

Continuing prior work by the author, a simple classical system for personal obligation is integrated with a fairly rich system for aretaic (agent-evaluative) appraisal. I then explore various relationships between definable aretaic statuses such as praiseworthiness and blameworthiness and deontic statuses such as obligatoriness and impermissibility. I focus on partitions of the normative statuses generated ("normative positions" but without explicit representation of agency). In addition to being able to model and explore fundamental questions in ethical theory about the connection between (...) blame, praise, permissibility and obligation, this allows me to carefully represent schemes for supererogation and kin. These controversial concepts have provided challenges to both ethical theory and deontic logic, and are among deontic logic's test cases. (shrink)

There are a number of concepts of common-sense morality, what one must do, what one ought to do, the supererogatory, the minimum that duty allows, the morally optional and the morally indifferent, that philosophers have been hard-pressed to represent in an integrated conceptual framework. Indeed, many philosophers have despaired at the attempt and concluded that only a fragment of these concepts belong to that fundamental sphere of morality that is the central focus of the ethicist. For example, the traditional scheme, (...) with its triad of the obligatory, the forbidden and the permissible, pigeonholes all actions into three mutually exclusive and exhaustive classes: those which are obligatory, those which are forbidden and those which are optional. Hence, at best, it can represent exactly two of the six aforementioned concepts. For from the standpoint of this scheme, what one must do and what one ought to do can't be distinguished and hence they can't both be represented. Although the morally optional can be represented, the supererogatory, one of its subclasses, cannot be represented. Furthermore, the morally indifferent, another subclass of the optional--one which is obviously disjoint from the supererogatory--cannot be represented. Finally, the minimum that duty allows finds no distinctive place in the traditional scheme. Thus, on the face of it, the traditional scheme is radically incomplete. ;I present, motivate and defend a new conceptual scheme for common-sense morality in which these concepts are represented and systematically integrated. An intuitively motivated semantic framework underpinning this conceptual scheme is also presented. Such a scheme, along with the associated semantic framework, is motivated by reflecting on the supererogationist's objections to utilitarianism and to the traditional scheme. But in addition, a new integrated network of linguistic motivations for this conceptual scheme is uncovered, one which is completely independent of supererogationistic considerations. Hence, these two separate sources of evidence for the centrality of this new scheme to our pre-theoretic thinking corroborate one another--thus jointly boosting the evidence beyond the mere sum of their separate evidential values.

I explore various ways of integrating the framework for predeterminism, agency, and ability in[P.McNamara, Nordic J. Philos. Logic 5 (2)(2000) 135] with a framework for obligations. However,the agential obligation operator explored here is defined in terms of a non-agential yet personal obligation operator and a non-deontic (and non-normal) agency operator. This is contrary to the main current trend, which assumes statements of personal obligation always take agential complements. Instead, I take the basic form to be an agent’s being obligated (...) to be such that p. I sketch some logics for agential obligation based on personal obligation and agency, first in a fairly familiar context that rules out conflicting personal obligations (and derivatively, conflicting agential obligations), and then in contexts that do allow for conflicts (of both sorts).

Cliff Landesman provides a vivid description of a case where we have no best outcome available to us. He poses this as a problem for utilitarians who advise us to do the best we can. This does indeed make such advice impractical. I begin by contrasting older versions of utilitarianism with newer ones that have appeared in deontic logic and that were designed precisely to accommodate Landesman's sort of scenario. (I cast matters in terms of the Limit Assumption and world-theoretic (...) versions of utilitarianism.) I then make three points. First, Landesman's problem does not pose any special problem for these newer theories. Secondly, I note that it is an interesting consequence of these newer theories being utilitarian theories, that--contrary to the tradition--utilitarianism isn't automatically a no conflicts theory of obligation. Thirdly, and most importantly, I identify a new, deeper and wider theoretical problem: "The Confinement Problem". This problem infests the newer versions of utilitarianism. Worse still, the infestation spreads to satisficing consequentialism (cf. Scheffler, Slote), the direction Landesman points to for a solution to his problem, and this new problem is one where the theoretical rulings of these theories clearly conflict with intuition.

This anthology contains revised versions of selected papers presented at the fourth bi-annual international deontic logic conference, DEON’98. This volume includes our substantial introduction, and an article from me as a contributor. The volume includes papers from all four distinguished invited speakers, David Makinson, Donald Nute, Claudio Pizzi, and the founder of deontic logic, Georg Von Wright. Other notables among the authors are Dov Gabbay (co-editor of the Handbook on Philosophical Logic vols.1-4, and editor of a number of logic book (...) series); Lars Lindahl (author of Position and Change: A Study in Law and Logic); Andrew Jones (past editor of the Norwegian Journal of Philosophical Logic, and the co-author of the entry “Deontic Logic and Contrary-to-Duties” in the 2nd edition of Handbook on Philosophical Logic); and Marek Sergot (a leading researcher at the interface of deontic logic and computer science.).

Leibniz' first problem with contingency stems from his doctrine of divine creation (not his later doctrine of truth) and is solved via his concepts of necessity per se, etc. (not via his later concept of infinite analysis). I scrutinize some of the earliest texts in which the first problem and its solution occur. I compare his "per se modal concepts" with his concept of analysis and with the traditional concept of metaphysical necessity. I then identify and remove the main obstacle (...) to Leibniz' employment of these concepts by reflecting on his concept of a world and comparing and contrasting it with contemporary conceptions. Finally I sketch the place that this early problem and its solution had in the context of his mature philosophy. A disagreement between Sleigh and Adams which hinges on the assumption that there is just one problem with competing solutions is seen to dissolve in this light. (shrink)

This anthology contains revised versions of selected papers presented at the the fourth bi-annual international deontic logic conference, DEON’06. There is a substantial introduction (see separate entry), papers from all four invited speakers, David Makinson, Donald Nute, Claudio Pizzi, and Georg Von Wright. After the introduction and lead chapter "Deontic Logic - as I See It" by G.H. von Wright, there are nineteen articles grouped under six headings, "Norms and Truth", "Agency and Time", "Analysis of Normative Conflicts", "Defeasibility and Norm (...) Conflicts", Computer System Applications", and "Combinations of Logics". The collection contains a number of influential articles and a large array of key authors in deontic logic contribute.

(See also the separate entry for the volume itself.) This introduction has three parts. The first providing an overview of some main lines of research in deontic logic: the emergence of SDL, Chisholm's paradox and the development of dyadic deontic logics, various other puzzles/challenges and areas of development, along with philosophical applications. The second part focus on some actual and potential fruitful interactions between deontic logic, computer science and artificial intelligence. These include applications of deontic logic to AI knowledge representation (...) in legal systems, to modelling computer systems where it is expected that sub-ideal states will emerge and require countermeasures, to norm-governed human interactions with computer systems, and to the representation of some features of multi-agent systems where different agent-like computer systems interact with one another. The third and final part briefly groups and previews the papers in the anthology. (shrink)

I recast the DWE ("Doing Well Enough") deontic framework as an Andersonian-Kangerian modal framework and explore its metatheory systematically.

Assuming minimal fine-individuation--that there are some necessarily equivalent intensional objects (e.g. propositions) that are nonetheless distinct objects, on standard actualist frameworks, the answer to our title question is "No". First I specify a fully cognitively accessible, purely qualitative maximal consistent state of affairs (MCS). (That there is an MCS that is either fully graspable or purely qualitative is in itself quite contrary to conventional dogma.) Then I identify another MCS, one necessarily equivalent to the first. It follows that there could (...) have been more than one obtaining MCS. I then argue that there is more than one obtaining MCS. So there is nothing answering to "the actual world", and the set of worlds is not the set of MCSs. I explore various patch-ups. Finally, I compare the actualist and modal realist notions of worlds, and I argue that even if the realist were right about concrete world ensembles, our reflections indicate that necessary truth is not truth in all worlds anyway, which undercuts the rationale for the realist's program. (shrink)

I first provide an accessible overview of the DWE (Doing Well Enough) logical and semantic framework for representing going beyond the call and its family of kindred concepts in a tightly intergraded way. Next, a module, for representing some basic agent-evaluative notions is developed (“AA” for “Aretaic Assessment”), and then it is integrated with the more act-evaluative notions of DWE, thereby allowing for a representation of suberogation and supererogation (as distinct from going beyond the call) and many other combined deontic (...) and agent-evaluative notions. I then probe more deeply into how the semantic structures for the DWE framework might themselves be generated and then offer some brief reflections on the classic supererogation puzzle, as well as that of supererogatory holes and the all or nothing problem, framing options via the preceding reflections.

Doubts are raised about Dretske’s assumption that an entity can't have a representational state that governs its behavior in virtue of its content unless that internal state has been acquired via appropriate interaction with its environment. The doubts hinge on a subtle distinction between a system's acquiring an internal representational state and a system's internal state acquiring the property of being representational. Employing this distinction, it is suggested that we can pre-load machines with states "destined" to acquire specific, predictable and (...) efficacious representational properties. The picture that results renders Dretske's general naturalistic approach to mental representation consistent with a tempered version of the classical dream in AI. (shrink)

Introduction and brief summary of revised symposium papers of Christopher Arroyo, David Cummiskey, Lydia Moland, and Stephan Bird-Pollan on the work of Professor Korsgaard and her replies. The symposia took place at the annual Northern New England Philosophical Association (NNEPA) conference, October 16–17, 2009, where Professor Korsgaard gave the keynote address, as well as participating in the symposia on her work, both held at the University of New Hampshire-Durham.

In "Doing Well Enough: Toward a Logic for Common Sense Morality", Paul McNamara sets out a semantics for a deontic logic which contains the operator It is supererogatory that. As well as having a binary accessibility relation on worlds, that semantics contains a relative ordering relation, . For worlds u, v and w, we say that u w v when v is at least as good as u according to the standards of w. In this paper we axiomatize (...) logics complete over three versions of the semantics. We call the strongest of these logics DWE for Doing Well Enough. (shrink)

Descartes is widely portrayed as the arch proponent of “the epistemological transparency of thought” (or simply, “Transparency”). The most promising version of this view—Transparency-through-Introspection—says that introspecting (i.e., inwardly attending to) a thought guarantees certain knowledge of that thought. But Descartes rejects this view and provides numerous counterexamples to it. I argue that, instead, Descartes’s theory of self-knowledge is just an application of his general theory of knowledge. According to his general theory, certain knowledge is acquired only through clear and distinct (...) intellection. Thus, in his view, certain knowledge of one’s thoughts is acquired only through clear and distinct intellection of one’s thoughts. Introspection is a form of intellection and it can be clear and distinct. Ordinarily, however, introspection isn’t clear and distinct but is instead confused with dubitable perceptions of bodies. To make introspection clear and distinct, we need to “sharply separate” it from all perceptions of bodies by doubting all perceptions of bodies. Without such radical doubt, introspection remains confused and we lack certain knowledge not just of the specific features of our thoughts, but even of the minimal claim that a thought exists. Far from being the high priest of Transparency, Descartes is radically opposed to it. (shrink)

In _Matter and Consciousness_, Paul Churchland presents a concise and contemporary overview of the philosophical issues surrounding the mind and explains the main theories and philosophical positions that have been proposed to solve them. Making the case for the relevance of theoretical and experimental results in neuroscience, cognitive science, and artificial intelligence for the philosophy of mind, Churchland reviews current developments in the cognitive sciences and offers a clear and accessible account of the connections to philosophy of mind. For (...) this third edition, the text has been updated and revised throughout. The changes range from references to the iPhone's "Siri" to expanded discussions of the work of such contemporary philosophers as David Chalmers, John Searle, and Thomas Nagel. Churchland describes new research in evolution, genetics, and visual neuroscience, among other areas, arguing that the philosophical significance of these new findings lies in the support they tend to give to the reductive and eliminative versions of materialism. Matter and Consciousness, written by the most distinguished theorist and commentator in the field, offers an authoritative summary and sourcebook for issues in philosophy of mind. It is suitable for use as an introductory undergraduate text. (shrink)

ABSTRACT Biobanks for long‐term research pose challenges to the legal and ethical validity of consent to participate. Different models of consent have been proposed to answer some of these challenges. This paper contributes to this discussion by considering the meaning and value of consent to participants in biobanks. Empirical data from a qualitative study is used to provide a participant view of the consent process and to demonstrate that, despite limited understanding of the research, consent provides the research participants with (...) some level of control and a form of self determination that they value. Participation is framed as a moral act of a responsible citizen providing reinforcement of self identity. Consent symbolizes the trust invested in researchers and research institutions to use the biobank for the public good. The paper argues that consent continues to play an important role in biobank participation and that a participant view should inform proposals to modify consent processes. (shrink)

The options in a decision problem generally have outcomes with common features. Putting aside the common features simplifies deliberations, but the simplification requires a philosophical justification that this book provides.

This book demonstrates how children's imagination makes a continuing contribution to their cognitive and emotional development.

We model scientific theories as Bayesian networks. Nodes carry credences and function as abstract representations of propositions within the structure. Directed links carry conditional probabilities and represent connections between those propositions. Updating is Bayesian across the network as a whole. The impact of evidence at one point within a scientific theory can have a very different impact on the network than does evidence of the same strength at a different point. A Bayesian model allows us to envisage and analyze the (...) differential impact of evidence and credence change at different points within a single network and across different theoretical structures.

We present a general framework for analyzing the contribution to reproductive success of a behavioural action. An action may make a direct contribution to reproductive success, but even in the absence of a direct contribution it may make an indirect contribution by changing the animal's state. We consider actions over a period of time, and define a reward function that characterizes the relationship between the animal's state at the end of the period and its future reproductive success. Working back from (...) the end of the period using dynamic programming, the optimal action as a function of state and time can be found. The procedure also yields a measure of the cost, in terms of future reproductive success, of a suboptimal action. These costs provide us with a common currency for comparing activities such as eating and drinking, or eating and hiding from predators. The costs also give an indication of the robustness of the conclusions that can be drawn from a model. We review how our framework can be used to analyze optimal foraging decisions in a stochastic environment. We also discuss the modelling of optimal daily routines and provide an illustration based on singing to attract a mate. We use the model to investigate the features that can produce a dawn song burst in birds. State is defined very broadly so that it includes the information an animal has about its environment. Thus, exploration and learning can be included within the framework. (shrink)

Philosophers of history posit a class of concepts known as colligatory concepts that contribute to historical consciousness and that refer specifically to historical events. Although analysis has identified colligatory concepts in historical discourse, these concepts have not yet been investigated empirically. We present a new methodology for studying these concepts and historical consciousness more broadly, as well as pilot data supporting the methodology. Our aim in the pilot study was to establish whether colligatory concepts are processed differently from control concepts (...) when subjects are asked to judge historical statements. We compared judgments of colligatory concepts in healthy participants and in a patient group with impaired working memory cognitive processing capacity. Forty healthy, college-educated participants and 25 patients with Parkinson's disease were asked to rate narrative sentences containing historical content and an equal number of identically constructed narrative sentences of equ..

The twentieth century has witnessed an unprecedented 'crisis in the foundations of mathematics', featuring a world-famous paradox (Russell's Paradox), a challenge to 'classical' mathematics from a world-famous mathematician (the 'mathematical intuitionism' of Brouwer), a new foundational school (Hilbert's Formalism), and the profound incompleteness results of Kurt Gödel. In the same period, the cross-fertilization of mathematics and philosophy resulted in a new sort of 'mathematical philosophy', associated most notably (but in different ways) with Bertrand Russell, W. V. Quine, and Gödel himself, (...) and which remains at the focus of Anglo-Saxon philosophical discussion. The present collection brings together in a convenient form the seminal articles in the philosophy of mathematics by these and other major thinkers. It is a substantially revised version of the edition first published in 1964 and includes a revised bibliography. The volume will be welcomed as a major work of reference at this level in the field.

The proposed multilevel framework of discourse comprehension includes the surface code, the textbase, the situation model, the genre and rhetorical structure, and the pragmatic communication level. We describe these five levels when comprehension succeeds and also when there are communication misalignments and comprehension breakdowns. A computer tool has been developed, called Coh-Metrix, that scales discourse (oral or print) on dozens of measures associated with the first four discourse levels. The measurement of these levels with an automated tool helps researchers track (...) and better understand multilevel discourse comprehension. Two sets of analyses illustrate the utility of Coh-Metrix in discourse theory and educational practice. First, Coh-Metrix was used to measure the cohesion of the text base and situation model, as well as potential extraneous variables, in a sample of published studies that manipulated text cohesion. This analysis helped us better understand what was precisely manipulated in these studies and the implications for discourse comprehension mechanisms. Second, Coh-Metrix analyses are reported for samples of narrative and science texts in order to advance the argument that traditional text difficulty measures are limited because they fail to accommodate most of the levels of the multilevel discourse comprehension framework.

Our scientific theories, like our cognitive structures in general, consist of propositions linked by evidential, explanatory, probabilistic, and logical connections. Those theoretical webs ‘impinge on the world at their edges,’ subject to a continuing barrage of incoming evidence. Our credences in the various elements of those structures change in response to that continuing barrage of evidence, as do the perceived connections between them. Here we model scientific theories as Bayesian nets, with credences at nodes and conditional links between them modelled (...) as conditional probabilities. We update those networks, in terms of both credences at nodes and conditional probabilities at links, through a temporal barrage of random incoming evidence. Robust patterns of punctuated equilibrium, suggestive of ‘normal science’ alternating with ‘paradigm shifts,’ emerge prominently in that change dynamics. The suggestion is that at least some of the phenomena at the core of the Kuhnian tradition are predictable in the typical dynamics of scientific theory change captured as Bayesian nets under even a random evidence barrage.
