This essay focuses on three recent books on morality and virtue, Michael Slote's 'Morals from Motives', Rosalind Hursthouse's 'On Virtue Ethics', and Philippa Foot's 'Natural Goodness'. Slote proposes an "agent-based" ethical theory according to which the ethical status of acts is derivative from assessments of virtue. Following Foot's lead, Hursthouse aims to vindicate an ethical naturalism that explains human goodness on the basis of views about human nature. Both Hursthouse and Slote take virtue to be morally basic in a way (...) that Foot, to her credit, does not. We argue that all three views face a range of serious difficulties. (shrink)

The proposal I offer attempts to remedy the inadequacies of exclusive focus on well-being for moral purposes. The proposal is this: We should allow the agent to decide for herself where she wants to throw the weight that is her due in moral reflection, with the proviso that she understands the way that her weight will be aggregated with others in reaching a moral outcome. I will call this the "autonomy principle." The autonomy principle, I claim, provides the consequentialist's best (...) prospect for taking people into account morally in a way that they endorse.

This paper articulates and defends a novel hybrid account of well-being. We will call our view a Robust Hybrid. We call it robust because it grants a broad and not subservient role to both objective and subjective values. In this paper we assume, we think plausibly but without argument, that there is a significant objective component to well-being. Here we clarify what it takes for an account of well-being to have a subjective component. Roughly, we argue, it must allow that (...) favoring attitudes that are not warranted by the lights of objective values can ground benefits. Given this understanding, we show that there is an important and unrecognized expansion in the resources available to fully objectivist views: namely that such views can help themselves to the value of warranted love of objective goods. Such a move by the objectivist can help them respond to concerns that, on their view, a person’s well-being can be too alien to them. We next argue that, nonetheless, such objectivist views are still unconvincing due to their lack of a subjective component. This motivates a move from fully objective accounts to hybrid accounts. We show that many prominent hybrid theories in the literature are inadequate because they implausibly minimize the subjective component. This motivates a move to a robust hybrid view that has an expanded subjectivist component. We conclude with some remarks about the interrelation between the subjective and objective components in the hybrid account that we favor and a role for resonance in a theory of well-being other than serving as a hard constraint on any benefit.

Consequentialism, many philosophers have claimed, asks too much of us to be a plausible ethical theory. Indeed, the theory's severe demandingness is often claimed to be its chief flaw. My thesis is that as we come to better understand this objection, we see that, even if it signals or tracks the existence of a real problem for Consequentialism, it cannot itself be a fundamental problem with the view. The objection cannot itself provide good reason to break with Consequentialism, because it (...) must presuppose prior and independent breaks with the view. The way the objection measures the demandingness of an ethical theory reflects rather than justifies being in the grip of key anti-Consequentialist conclusions. We should reject Consequentialism independently of the Objection or not at all. Thus, we can reduce by one the list of worrisome fundamental complaints against Consequentialism. (shrink)

Libertarian self-ownership views have traditionally maintained that we enjoy very powerful deontological protections against any infringement upon our property. This stringency yields very counter-intuitive results when we consider trivial infringements such as very mildly toxic pollution or trivial risks such having planes fly overhead. Maintaining that other people's rights against all infringements are very powerful threatens to undermine our liberty, as Nozick saw. In this paper I consider the most sophisticated attempts to rectify this problem within a libertarian self-ownership framework. (...) I argue that all of these responses are significantly flawed.

We argue that Parfit's "Triviality Objection" against some naturalistic views of normativity is not compelling. We think that once one accepts, as one should, that identity statements can be informative in virtue of their pragmatics and not only in virtue of their semantics, Parfit's case against naturalism can be overcome.

I argue that Parfit's On What Matters does not make a compelling case against subjective accounts of reasons for action.

Derek Parfit, in On What Matters, argues that all subjective accounts of normative reasons for action are false. This chapter focuses on his “Agony Argument.” The first premise of the Agony Argument is that we necessarily have current reasons to avoid our own future agony. Its second premise is that subjective accounts cannot vindicate this fact. So, the argument concludes, subjective accounts must be rejected. This chapter accepts the first premise of this argument and that it is valid. The main (...) thesis of this chapter is that subjectivists can account for our reasons to get pleasure and avoid agony. The chapter concludes that the Agony Argument does not justify the rejection of subjective accounts. The chapter also examines Parfit's understanding of the distinction between objective and subjective theories. The chapter claims Parfit offers a surprisingly narrow understanding of subjectivism such that even if his critique were successful, this would be bad news for fewer theories than we might have thought. Finally, the chapter replies to some possible worries about the arguments of this chapter. (shrink)

People are adept at inferring novel causal relations, even from only a few observations. Prior knowledge about the probability of encountering causal relations of various types and the nature of the mechanisms relating causes and effects plays a crucial role in these inferences. We test a formal account of how this knowledge can be used and acquired, based on analyzing causal induction as Bayesian inference. Five studies explored the predictions of this account with adults and 4-year-olds, using tasks in which (...) participants learned about the causal properties of a set of objects. The studies varied the two factors that our Bayesian approach predicted should be relevant to causal induction: the prior probability with which causal relations exist, and the assumption of a deterministic or a probabilistic relation between cause and effect. Adults’ judgments (Experiments 1, 2, and 4) were in close correspondence with the quantitative predictions of the model, and children’s judgments (Experiments 3 and 5) agreed qualitatively with this account.

Libertarian self-ownership views in the tradition of Locke, Nozick, and the left-libertarians have supposed that we enjoy very powerful deontological protections against infringing upon our property. Such a conception makes sense when we are focused on property that is very important to its owner, such as a person’s kidney. However, this stringency of our property rights is harder to credit when we consider more trivial infringements such as very mildly toxic pollution or trivial risks such having planes fly overhead. Maintaining (...) that our rights against all infringements are very powerful threatens to implausibly make such pollution and trivial risk broadly impermissible. This paper suggests that self-ownership views have tended to inappropriately conflate the seriousness of different types of infringements and that treating all infringements so seriously is implausible because it would make too much impermissible. I consider several ways to avoid this result within a self-ownership framework and conclude that the best approach is to allow that the strength of the protection against infringements should be tied to the seriousness of the harm of the infringement.

Phillips et al. present a number of arguments for the premise that knowledge is more basic than belief. Although their arguments are coherent and sound, they do not directly address numerous cases in which belief appears to be a developmental precursor to knowledge. I describe several examples, not necessarily as a direct challenge, but rather to better understand their framework.

My favorite thing about this paper is that I think I usefully explicate and then mess with Bernard Williams's attempt to explain how his internalism is compatible with our ordinary practices of blame. There are a surprising number of things wrong with Williams's position. Of course that leaves my own favored subjectivism in a pickle, but still...

Many philosophers maintain that neither one’s reasons for action nor well-being are ever grounded in facts about what we desire or favor. Yet our reasons to eat a flavor of ice cream we like rather than one we do not seem an obvious counter-example. I argue that there is no getting around such examples and that therefore a fully stance independent account of the grounding of our reasons is implausible. At least in matters of mere taste our “stance” plays a (...) normative role in grounding reasons. (shrink)

Richard Kraut's neo-Aristotelian account of well-being, Developmentalism, aspires to explain not only which things are good for us but why those things are good for us. The key move in attempting to make good on this second aspiration involves his claim that our ordinary intuitions about what is good for a person can be successfully explained and systematized by the idea that what benefi ts a living thing develops properly that living thing's potentialities, capacities, and faculties. I argue that Kraut's (...) understanding of such proper development plays no serious constraining role in shaping the details of the account. If this is correct, Developmentalism lacks the potential to explain or vindicate the intuitions about what is good for us that it champions. In effect, Kraut offers us a list of things that he claims benefits a person, but he lacks a theory of what those things have in common such that they benefit him. (shrink)

There are two common assumptions about well-being that I am especially concerned to dispute in this dissertation. The first assumption is that differences in kinds of prudential values can be reduced to differences in amount of prudential value. That is, that differences in the qualities of values can reliably be reduced to mere differences in quantity. The second assumption is that well-being is the appropriate object of moral concern. Consequentialist moral theories typically argue that morality requires the maximization of well-being (...) across persons. Thus, such consequentialists suggest, the way to take another into account morally is to promote that person's well-being. ;Against the first assumption I take issue with hedonism, decision theory, and full information accounts of well-being. I argue that none of these popular methods of commensurating well-being is adequate to the task. Against the second assumption, I argue that, properly construed, one's well-being does not adequately capture the full range of one's concerns. I argue that this is a crucial fault with well-being promoting ethical theories. I suggest instead that we allow people to throw their weight in the moral calculus where they choose, provided that they understand the aggregation procedure. (shrink)

The authors argue that children prefer fictions with imaginary worlds. But evidence from the developmental literature challenges this claim. Children's choices of stories and story events show that they often prefer realism. Further, work on the imagination's relation to counterfactual reasoning suggests that an attraction to unrealistic fiction would undermine the imagination's role in helping children understand reality.

I assess Schroeder's book Slaves of the Passions and isolate some grounds for concerns about the overall position.

In museum settings, caregivers support children's learning as they explore and interact with exhibits. Museums have developed exhibit design and facilitation strategies for promoting families' exploration and inquiry, but these strategies have rarely been contrasted. The goal of the current study was to investigate how prompts offered through staff facilitation vs. labels printed on exhibit components affected how family groups explored a circuit blocks exhibit, particularly whether children set and worked toward their own goals, and how caregivers were involved in (...) children's play. We compared whether children, their caregivers, or both set goals as they played together, and the actions they each took to connect the circuits. We found little difference in how families set goals between the two conditions, but did find significant differences in caregivers' actions, with caregivers in the facilitation condition making fewer actions to connect circuits while using the exhibit, compared to caregivers in the exhibit labels condition. The findings suggest that facilitated and written prompts shape the quality of caregiver-child interactions in distinct ways. (shrink)

A BAYESIAN ARTICULATION OF HUME’S VIEWS IS OFFERED BASED ON A FORM OF THE BAYES-LAPLACE THEOREM THAT IS SUPERFICIALLY LIKE A FORMULA OF CONDORCET’S. INFINITESIMAL PROBABILITIES ARE EMPLOYED FOR MIRACLES AGAINST WHICH THERE ARE ’PROOFS’ THAT ARE NOT OPPOSED BY ’PROOFS’. OBJECTIONS MADE BY RICHARD PRICE ARE DEALT WITH, AND RECENT EXPERIMENTS CONDUCTED BY AMOS TVERSKY AND DANIEL KAHNEMAN ARE CONSIDERED IN WHICH PERSONS TEND TO DISCOUNT PRIOR IMPROBABILITIES WHEN ASSESSING REPORTS OF WITNESSES.

David Gauthier stages a competition between two arguments, each of which purports to decide once for all transparent agents which is best, being a straight or being a constrained maximizer. The first argument, which he criticizes and rejects, is for the greater utility, on a certain weak assumption, of straight maximization for all transparent agents. The second, which he endorses, is for the greater utility on the same weak assumption of constrained maximization for all transparent agents.In Section I, Gauthier’s (...) account of constrained maximization is presented, and his use in the two arguments of the idea of choosing a disposition to choose actions is noted. Section II is about the unfortunate argument that Gauthier criticizes. This argument is flawed in ways additional to those he notices, but a less ambitious form of reasoning can, for individuals whose probabilities and values are right, be good for the greater expected utility of straight maximization. Section III takes up the argument that Gauthier endorses and maintains that it is wrong in a way specific to it as well as in ways closely related to all of the first argument’s noted flaws. An Appendix features a three-person prisoners’ dilemma and includes demonstrations of principal conclusions reached in the body of this paper. (shrink)

This paper is about David Gauthier’s concept of constrained maximization. Attending to his most detailed and careful account, I try to say how constrained maximization works, and how it might be changed to work better. In section I, that detailed account is quoted along with amplifying passages. Difficulties of interpretation are explained in section II. An articulation, a spelling out, of Gauthier's account is offered in section III to deal with these difficulties. Next, in section IV, constrained maximization thus (...) articulated is tested on several choice problems and shown to be seriously wanting. It appears that there are prisoners’ dilemmas in which constrained maximizers would not cooperate to mutual advantage, but would interact sub-optimally just as straight-maximizers would. ‘Coordination problems’ are described with which constrained maximizers might, especially if transparent to one another, not be able to cope–problems in which they might not be able to make up their minds to do anything at all. And I prove that there are prisoners’ dilemmas that, though possible for real agents and for straight maximizers, are not possible for constrained maximizers, so that agents’ internalising dispositions of constrained maximization could not be of help in connection with such possibly impending dilemmas. Taking constrained maximization as it stands, there are many problems for which it does not afford the ‘moral solutions’ with which Gauthier would have it replace Hobbesian political ones. After displaying these shortcomings of constrained maximization as presently designed, I sketch, in section V, possible revisions that would reduce them, stressing that these revisions would not be cost-free. Whether finishing the job of fixing up and making precise constrained maximization would be worth the considerable trouble it would involve lies beyond the issues taken up in this paper. So, of course, do substantive comparisons of constrained maximization, perfected and made precise, and straight maximization. (shrink)

La théorie économique marxiste rend compte des rapports entre capitalisme et violence à l’aide notamment du concept d’accumulation primitive.

By his definition of them, David Gauthier's co-operative constrained maximizers are not necessarily unsharing and disposed to exclude straight maximizers from benefits of their co-operation. Here is Gauthier's full and exact account, his official account, of constrained maximization.

In this essay, I propose a standard of practical rationality and a grounding for the standard that rests on the idea of autonomous agency. This grounding is intended to explain the “normativity” of the standard. The basic idea is this: To be autonomous is to be self-governing. To be rational is at least in part to be self-governing; it is to do well in governing oneself. I argue that a person's values are aspects of her identity—of her “self-esteem identity”—in a (...) way that most of her ends are not, and that it therefore is plausible to view action governed by one's values as self-governed. This is also plausible on independent grounds. Given this, I say, rational agents comply with a standard—the “values standard”—that requires them to serve their values, and to seek what they need in order to continue to be able to serve their values.

Many philosophers interested in the nature of moral or other normative truths and facts are attracted to response-dependence accounts. They think, in other words, that the target normative facts are reducible to, or constituted by, or identical with, some facts involving our relevant responses. But these philosophers rarely allow all of our actual responses (of the relevant kind) to play such a role. Rather, they privilege some..

David Johnson seeks to overthrow one of the widely accepted tenets of Anglo-American philosophy—that of the success of the Humean case against the rational credibility of reports of miracles. In a manner unattempted in any other single work, he meticulously examines all the main variants of Humean reasoning on the topic of miracles: Hume's own argument and its reconstructions by John Stuart Mill, J. L. Mackie, Antony Flew, Jordan Howard Sobel, and others. Hume's view, set forth in his (...) essay "Of Miracles," has been widely thought to be correct. Johnson reviews Hume's thesis with clarity and elegance and considers the arguments of some of the most prominent defenders of Hume's case against miracles. According to Johnson, the Humean argument on this topic is entirely without merit, its purported cogency being simply a philosophical myth. (shrink)

We propose a formal framework for interpretable machine learning. Combining elements from statistical learning, causal interventionism, and decision theory, we design an idealised explanation game in which players collaborate to find the best explanation for a given algorithmic prediction. Through an iterative procedure of questions and answers, the players establish a three-dimensional Pareto frontier that describes the optimal trade-offs between explanatory accuracy, simplicity, and relevance. Multiple rounds are played at different levels of abstraction, allowing the players to explore overlapping causal (...) patterns of variable granularity and scope. We characterise the conditions under which such a game is almost surely guaranteed to converge on a optimal explanation surface in polynomial time, and highlight obstacles that will tend to prevent the players from advancing beyond certain explanatory thresholds. The game serves a descriptive and a normative function, establishing a conceptual space in which to analyse and compare existing proposals, as well as design new and improved solutions. (shrink)

This paper describes differences in two perspectives on the idea of virtue as a theoretical foundation for positive organizational ethics (POE). The virtue ethics perspective is grounded in the philosophical tradition, has classical roots, and focuses attention on virtue as a property of character. The positive social science perspective is a recent movement (e.g., positive psychology and positive organizational scholarship) that has implications for POE. The positive social science movement operationalizes virtue through an empirical lens that emphasizes virtuous behaviors. From (...) a virtue ethics perspective, a behaviorally based account of virtue is a weak theory of virtue. Observations are suggested for integrating the two perspectives. First, virtue should always be understood as an excellence and is often an optimal point between extreme dysfunctions on continuum of potential states. Second, an empirical exploration of virtue needs to account for character and context. Finally, the properties of organization-level virtue need to be further specified and explored. Implications and directions for future research are discussed. (shrink)

_Real Essentialism_ presents a comprehensive defence of neo-Aristotelian essentialism. Do objects have essences? Must they be the kinds of things they are in spite of the changes they undergo? Can we know what things are really like – can we define and classify reality? Many, if not most, philosophers doubt this, influenced by centuries of empiricism, and by the anti-essentialism of Wittgenstein, Quine, Popper, and other thinkers. _Real Essentialism_ reinvigorates the tradition of realist, essentialist metaphysics, defending the reality and knowability (...) of essence, the possibility of objective, immutable definition, and its relevance to contemporary scientific and metaphysical issues such as whether essence transcends physics and chemistry, the essence of life, the nature of biological species, and the nature of the person.

Virtuousness refers to the pursuit of the highest aspirations in the human condition. It is characterized by human impact, moral goodness, and unconditional societal betterment. Several writers have recently argued that corporations, in addition to being concerned with ethics, should also emphasize an ethos of virtuousness in corporate action. Virtuousness emphasizes actions that go beyond the “do no harm” assumption embedded in most ethical codes of conduct. Instead, it emphasizes the highest and best of the human condition. This research empirically (...) examines the buffering and amplifying effects of virtuousness in organizations. The study hypothesizes that virtuousness has a positive effect on organizations because amplifying dynamics make subsequent virtuous action more likely, and buffering dynamics reduce the harmful effects of downsizing. The study reveals that two types of virtuousness – tonic and phasic – are associated with these effects. (shrink)

BackgroundAs suggested by Shook and Giordano, understanding and therefore addressing the urgent international governance issues around globalizing bio-medical/technology research and applications is limited by the perception of the underlying science.MethodsA philosophical methodology is used, based on novel and classical philosophical reflection upon existent literature, clinical wisdoms and narrative theory to discover a meta-science and telos of humankind for the development of a relevant and defendable global biomedical bioethics.ResultsIn this article, through pondering an integrative systems approach, I propose a biomedical model (...) that may provide Western biomedicine with leadership and interesting insight into the unity beyond the artificial boundaries of its traditional divisions and the limit between physiological and pathological situations. A unified biomedicine, as scientific foundation, might then provide the basis for dissolution of similar reflected boundaries within bioethics. A principled and communitarian cosmopolitan bioethics may then be synonymous with a recently proposed principled and communitarian cosmopolitan neuroethics based on a novel objective meta-ethics. In an attempt to help facilitate equal and inclusive participation in inter-, multi-, and transdisciplinary intercultural discourse regarding the aforementioned international governance issues, I offer: a meta-science derived through considering the general behaviour of activity, plasticity and balance in biology and; a novel thought framework to encourage and enhance the ability for self-evaluation, self-criticism, and self-revision aimed at broadening perspective, as well as acknowledging and responding to the strengths and limitations of extant knowledge.ConclusionsThrough classical philosophical reflection, I evolve a theory of medicine to discover a telos of humankind which in turn provides an ‘internal’ moral grounding for a proposed global biomedical bioethics.

Machine learning algorithms may radically improve our ability to diagnose and treat disease. For moral, legal, and scientific reasons, it is essential that doctors and patients be able to understand and explain the predictions of these models. Scalable, customisable, and ethical solutions can be achieved by working together with relevant stakeholders, including patients, data scientists, and policy makers.

As machine learning has gradually entered into ever more sectors of public and private life, there has been a growing demand for algorithmic explainability. How can we make the predictions of complex statistical models more intelligible to end users? A subdiscipline of computer science known as interpretable machine learning (IML) has emerged to address this urgent question. Numerous influential methods have been proposed, from local linear approximations to rule lists and counterfactuals. In this article, I highlight three conceptual challenges that (...) are largely overlooked by authors in this area. I argue that the vast majority of IML algorithms are plagued by (1) ambiguity with respect to their true target; (2) a disregard for error rates and severe testing; and (3) an emphasis on product over process. Each point is developed at length, drawing on relevant debates in epistemology and philosophy of science. Examples and counterexamples from IML are considered, demonstrating how failure to acknowledge these problems can result in counterintuitive and potentially misleading explanations. Without greater care for the conceptual foundations of IML, future work in this area is doomed to repeat the same mistakes. (shrink)

We examine two different descriptions of the behavioral functions of the hippocampal system. One emphasizes spatially organized behaviors, especially those using cognitive maps. The other emphasizes memory, particularly working memory, a short-term memory that requires iexible stimulus-response associations and is highly susceptible to interference. The predictive value of the spatial and memory descriptions were evaluated by testing rats with damage to the hippocampal system in a series of experiments, independently manipulating the spatial and memory characteristics of a behavioral task. No (...) dissociations were found when the spatial characteristics of the stimuli to be remembered were changed; lesions produced a similar deficit in both spatial and nonspatial test procedures, indicating that the hippocampus was similarly involved regardless of the spatial nature of the task. In contrast, a marked dissociation was found when the memory requirements were altered. Rats with lesions were able to perform accurately in tasks that could be solved exclusively on the basis of reference memory. They performed at chance levels and showed no signs of recovery even with extensive postoperative training in tasks that required working memory. In one experiment all the characteristics of the reference memory and working memory procedures were identical except the type of memory required. Consequently, the behavioral dissociation cannot be explained by differences in attention, motivation, response inhibition, or the type of stimuli to be remembered. As a result of these experiments we propose that the hippocampus is selectively involved in behaviors that require working memory, irrespective of the type of material that is to be processed by that memory.

DCPS is a connectionist production system interpreter that uses distributed representations. As a connectionist model it consists of many simple, richly interconnected neuron‐like computing units that cooperate to solve problems in parallel. One motivation for constructing DCPS was to demonstrate that connectionist models are capable of representing and using explicit rules. A second motivation was to show how “coarse coding” or “distributed representations” can be used to construct a working memory that requires far fewer units than the number of different (...) facts that can potentially be stored. The simulation we present is intended as a detailed demonstration of the feasibility of certain ideas and should not be viewed as a full implementation of production systems. Our current model only has a few of the many interesting emergent properties that we eventually hope to demonstrate: It is damage‐resistant, it performs matching and variable binding by massively parallel constraint satisfaction, and the capacity of its working memory is dependent on the similarity of the items being stored.

The public forum has been connected to the functioning of democracy, expressive freedom, and the media's role in society. While the public forum's legal contours have been examined, the ethical foundation of the public forum has not. Relying on archival research, this article argues that ideas about the public forum can be traced to the pragmatism of Grenville Clark, who influenced ideas about the public forum through his work on the American Bar Association's Bill of Rights Committee.
