The recent emergence of machine-manipulated media raises an important societal question: How can we know whether a video that we watch is real or fake? In two online studies with 15,016 participants, we present authentic videos and deepfakes and ask participants to identify which is which. We compare the performance of ordinary human observers with the leading computer vision deepfake detection model and find them similarly accurate, while making different kinds of mistakes. Together, participants with access to the model’s prediction (...) are more accurate than either alone, but inaccurate model predictions often decrease participants’ accuracy. To probe the relative strengths and weaknesses of humans and machines as detectors of deepfakes, we examine human and machine performance across video-level features, and we evaluate the impact of preregistered randomized interventions on deepfake detection. We find that manipulations designed to disrupt visual processing of faces hinder human participants’ performance while mostly not affecting the model’s performance, suggesting a role for specialized cognitive capacities in explaining human deepfake detection performance. -/- .

Both liberals and feminists have long criticized the paternalistic approach to prostitution found in most jurisdictions in the U.S. In his recent book Prostitution and Liberalism, Peter de Marneffe defends just such an intervention, arguing that the demonstrated harmfulness of a life of prostitution justifies paternalistic policies aimed at reducing the number of women who are involved in it. Although de Marneffe does not endorse the prohibitionist approach typical in the U.S., he argues that the best reasons for alternative approaches (...) to the practice (including some forms of regulated legalization) are necessarily paternalistic. In my paper, I question de Marneffe’s contention that the strongest reasons for state intervention with regard to prostitution are paternalistic in nature. I argue that reasonable state action toward prostitution is best understood not as a paternalistic intervention to remedy some moral or epistemological failure on the part of prostitutes, but rather as an attempt to advance the interests of vulnerable parties more generally concerning what they reasonably desire but could not otherwise ensure. I further argue that such an approach might favor abolitionist over regulatory policies, depending upon how the vulnerable class is defined. (shrink)

Barbara Herman's account of rules of moral salience goes far in explaining how Kantian moral theory can integrate historically emergent normative criticisms such as that offered by feminists. The ethical motives that initially lead historical agents to expand our moral categories, however, are often at odds with Kant's (and Herman's) theory of moral motivations. I argue that Hegel offers a more accurate account of ethical motivation under oppressive conditions.

Biobanks act as the custodians for the access to and responsible use of human biological samples and related data that have been generously donated by individuals to serve the public interest and scientific advances in the health research realm. Risk assessment has become a daily practice for biobanks and has been discussed from different perspectives. This paper aims to provide a literature review on risk assessment in order to put together a comprehensive typology of diverse risks biobanks could potentially face. (...) Methodologically set as a typology, the conceptual approach used in this paper is based on the interdisciplinary analysis of scientific literature, the relevant ethical and legal instruments and practices in biobanking to identify how risks are assessed, considered and mitigated. Through an interdisciplinary mapping exercise, we have produced a typology of potential risks in biobanking, taking into consideration the perspectives of different stakeholders, such as institutional actors and publics, including participants and representative organizations. With this approach, we have identified the following risk types: economic, infrastructural, institutional, research community risks and participant’s risks. The paper concludes by highlighting the necessity of an adaptive risk governance as an integral part of good governance in biobanking. In this regard, it contributes to sustainability in biobanking by assisting in the design of relevant risk management practices, where they are not already in place or require an update. The typology is intended to be useful from the early stages of establishing such a complex and multileveled biomedical infrastructure as well as to provide a catalogue of risks for improving the risk management practices already in place.

Dans ce texte, nous analysons la mise en place d’un système de vélos partagés à Trois-Rivières initié par un organisme faisant de la participation citoyenne son principe fondamental d’action. Cette analyse montre comment l’atteinte des objectifs poursuivis par l’adhésion à ce principe participatif, outre le respect de l’expérience du citoyen dans le développement de son milieu de vie, peut poser problème. La similarité entre le système de vélos conçu avec la participation des citoyens et les systèmes offerts par les groupes (...) industriels met en question la capacité du principe de la participation à produire des solutions alternatives. La difficulté relèverait de la volonté de faire des méthodes participatives un principe nécessaire à la réalisation des idéaux démocratiques des sociétés libérales modernes. Promulguer l’obéissance à des procédures d’action com- munes, pour elles-mêmes, nous éloigne d’une conception libérale de la démocratie qui s’attache d’abord à l’efficacité de l’action, donc à la qualité de ce qu’elle produit, indépendamment des moyens mis en œuvre.

Gauthier claims: (1) a non-maximizing action is rational if it maximized to intend it. If one intended to retaliate in order to deter an attack, (2) retaliation is rational, for it maximized to intend it. I argue that even on sympathetic theories of intentions, actions and choices, (1) is incoherent. But I defend (2) by arguing that an action is rational if it maximizes on preferences it maximized to adopt given one's antecedent preferences. (2) is true because it maximized (...) to adopt preferences on which it maximizes to retaliate. I thus save the theory that rational actions must maximize, and extend it into the rational criticism of preferences. (shrink)

In "Morals by Agreement", David Gauthier attempts to derive property rights from a moral principle called the Lockean proviso. The derivation fails, and the true implications of the moral principles which Gauthier invokes are quite different. These principles imply that persons have extensive liberties to use physical materials, but relatively few rights against interference by others in this use. Robert Nozick argues for an extensive system of property rights in "Anarchy, State, and Utopia"; his argument fails for similar (...) reasons. (shrink)

Gauthier’s contractarianism begins with an idea of a rational deliberator but ‘finds no basis for postulating a moral need for the justification of one’s actions to others. The role of agreement is to address each person’s demand that the constraints of society be justified to him, not a concern that he justify himself to his fellows’ (Gauther 1997, 134–5). He contrasts his view with Scanlon’s contractualism, according to which agreement with others is the core of morality and each agent (...) has the burden of justifying his or her actions to others. Both of their views count as ‘constructivist’ because they reject moral realism and hold that normativity is a function of what we do, either individually or collectively. Kant’s Rechtslehre is neutral regarding moral realism and yet constructivist about moral norms. However, the relevant acts basic to Gauthier’s and Scanlon’s views concern voluntary agreements we make. Using agreement to establish basic norms faces some serious difficulties. Kant’s Rechtslehre avoids these problems by showing how basic social norms can be identified and justified independently of voluntary agreement. Moreover, it does so in a way that shows that an individual’s justification of his or her acts to others and the justification of the acts of others to any individual are inseparable aspects of one and the same justificatory reasons in which voluntary agreement plays no role.

David Gauthier thinks agents facing a prisoner's dilemma ('pd') should find it rational to dispose themselves to co-operate with those inclined to reciprocate (i.e., to acquire a constrained maximizer--'cm'--disposition), and to co-operate with other 'cmers'. Richmond Campbell argues that since dominance reasoning shows it remains to the agent's advantage to defect, his co-operation is only rational if cm "determines" him to co-operate, forcing him not to cheat. I argue that if cm "forces" the agent to co-operate, he is not (...) acting at all, never mind rationally. Thus, neither author has shown that co-operation is rational action in a pd. (shrink)

Internal Logic brings together several threads of Yvon Gauthier's work on the foundations of mathematics and revisits his attempt to, as he puts it, radicalize Hilbert's Program. A radicalization of Hilbert's Program, I take it, is supposed to take Hilberts' finitary viewpoint more seriously than other attempts to salvage Hilbert's Program have. Such a return to the "roots of Hilbert's metamathematical idea" will, so claims Gauthier, enable him to save Hilbert's Program.

Gauthier's version of the Lockean proviso (in Morals by Agreement) is inappropriate as the foundation for moral rights he takes it to be. This is so for a number of reasons. It lacks any proportionality test thus allowing arbitrarily severe harms to others to prevent trivial harms to oneself. It allows one to inflict any harm on another provided that if one did not do so, someone else would. And, by interpreting the notion of bettering or worsening one's position (...) in terms of subjective expected utility, it allows immoral manipulation of others and imposes unwarranted restrictions based on preferences that should carry no moral weight. (shrink)

David Gauthier suggested that all genuine moral problems are Prisoners Dilemmas (PDs), and that the morally and rationally required solution to a PD is to co-operate. I say there are four other forms of moral problem, each a different way of agents failing to be in PDs because of the agents’ preferences. This occurs when agents have preferences that are malevolent, self-enslaving, stingy, or bullying. I then analyze preferences as reasons for action, claiming that this means they must not (...) target the impossible, they must be able to be acted on in the circumstances, their targets must be attainable, and having the preferences must make their targets more likely. For groups of agents to have a distribution of preferences, their preferences must jointly have those four features, this imposing a kind of universalizability requirement on possible preferences. I then claim that, if all agents began with preferences satisfying these requirements, their preferences would not be of the morally problematic sort (on pain, variously, of circularity or contradiction in the specification of their targets). Instead, they would be either morally innocent preferences, or ones which put the agents in PDs. And it would then be instrumentally rational for the agents to prefer mutual co-operation. Thus if all agents initially had rationally permissible preferences and made rational choices of actions and preferences thereafter, they would never acquire immoral preferences, and so never be rationally moved to immoral actions. Further, the states of affairs such agents would be moved to bring about would be compatible with what Rawls’ agents would chose behind a veil of ignorance. Morality therefore reduces to rationality; necessarily, the actions categorically required by morality are also categorically required by rationality. (shrink)

Theories of practical rationality say when it is rational to form and fulfill intentions to do actions. David Gauthier says the correct theory would be the one our obeying would best advance the aim of rationality, something Humeans take to be the satisfaction of one’s desires. I use this test to evaluate the received theory and Gauthier’s 1984 and 1994 theories. I find problems with the theories and then offer a theory superior by Gauthier’s test and immune (...) to the problems. On this theory, it is rational to treat something different as the aim when doing so would advance the original aim. I argue that the idea that this would be irrational bad faith entails contradictions and so is false, as must be theories saying that rationally we must always treat as the aim the bringing about of objectively good states of affairs or obeying a universalizable moral code. (Note: the published version differs somewhat from the version on the website of the Center for Ethics and the Rule of Law; please quote from the published version.). (shrink)

Gauthier and Hobbes reduce Prisoners Dilemmas to co-ordination problems (CPs). Many think rational, face-to-face agents can solve any CP by agreed fiat. But though an agent can rationally use a symmetry-breaking technique (ST) to decide between equal options, groups cannot unless their members' STs luckily converge. Failing this, the CP is escapable only by one agent's non-rational stubbornness, or by the group's "conquest" by an outside force. Implications: one's strategic rationality is group-relative; there are some optimums groups in principle (...) cannot rationally choose; thus justice cannot always be a rationally contracted optimum. Howard Sobel provides the point of departure. (shrink)

I argue that Gauthier's constrained-maximizer rationality is problematic. But standard Maximizing Rationality means one's preferences are only rational if it would not maximize on them to adopt new ones. In the Prisoner's Dilemma, it maximizes to adopt conditionally cooperative preferences. (These are detailed, with a view to avoiding problems of circularity of definition.) Morality then maximizes. I distinguish the roles played in rational choices and their bases by preferences, dispositions, moral and rational principles, the aim of rational action, and (...) rational decision rules. I argue that Maximizing Rationality necessarily structures conclusive reasons for action. Thus conations of any sort can base rational choices only if the conations are structured like a coherent preference function; rational actions maximize on such functions. Maximization-constraining dispositions cannot integrate into a coherent preference function. (shrink)

Several authors, including Thomas Nagel and David Gauthier, have defended the view that reasons of self-interest (prudential reasons) are rationally binding. That is, there is always a reason, bearing on the rational advisability, based on one's self-interest and, as a result, a person may act irrationally by knowingly acting against such reasons regardless of the person's desires or values. Both Nagel and Gauthier argue from the rationally mandatory nature of prudential reasons to the conclusion that moral reasons can (...) be rationally mandatory, challenging the neo-Humean position that practical reasons that bear on an agent's rationality are essentially grounded on the agent's subjective, contingent, conative states. I argue, pace Nagel and Gauthier, that prudential reasons are not rationally mandatory--that the rational requirement to act in one's own interest, when it exists, is, as the neo-Humean insists, grounded on one's subjective, contingent, conative states. Prudential reasons are not reasons for every (conceivable) agent--not in the sense that bears on the rational advisability of action. (shrink)

Gregory Kavka's 'Toxin Puzzle' suggests that I cannot intend to perform a counter-preferential action A even if I have a strong self-interested reason to form this intention. The 'Rationalist Solution,' however, suggests that I can form this intention. For even though it is counter-preferential, A-ing is actually rational given that the intention behind it is rational. Two arguments are offered for this proposition that the rationality of the intention to A transfers to A-ing itself: the 'Self-Promise Argument' and David (...) class='Hi'>Gauthier's 'Rational Self-Interest Argument.' But both arguments – and therefore the Rationalist Solution – fail. The Self-Promise Argument fails because my intention to A does not constitute a promise to myself that I am obligated to honor. And Gauthier's Rational Self-Interest Argument fails to rule out the possibility of rational irrationality. (shrink)

This paper reviews six attempts to give cooperative solutions to Prisoners Dilemmas: symmetry (agents are in identical situations, so should choose the same way, so should both choose cooperation because that’s better for each), mechanism (each agent should delegate the decision to a machine which will choose cooperation for them provided the other does likewise), inducement (the agents should make a side bet which pays off only upon both cooperating), resolution (each agent should resolve to cooperate, then act on the (...) resolution), alternative principle (rationality requires not dominance reasoning and so defecting, but constrained maximization or resolution compliance or “sophisticated” choosing, and so cooperation), and preference revision (each agent should acquire conditional preferences to cooperate, then cooperate provided the other agent has acquired similar preferences). It distinguishes one-stage from two-stage games, as well as endogenously available solutions (ones available to agents in the circumstances of the game merely due to the nature of rationality) from solutions requiring exogenous devices. It contrasts Edward McClennen’s endogenous solution, which is some combination of resolution and alternative principle solution, with David Gauthier’s endogenous alternative principle solution. It argues that all have problems, ones best solved by the endogenous preference revision solution defended by Duncan MacIntosh. (shrink)

James Sterba describes the egoist as thinking only egoist reasons decide the rationality of choices of action, the altruist, only altruistic reasons, that each in effect begs the question of what reasons there are against the other, and that the only non-question-begging and therefore rationally defensible position in this controversy is the middle-ground position that high-ranking egoistic reasons should trump low ranking-altruistic considerations and vice versa, this position being co-extensive with morality. Therefore it is rationally obligatory choose morally. I object (...) that the mere fact that a position is intermediate between two extremes does not mean it isn’t question-begging; that Sterba’s style of argument could be used to prove anything and therefore proves nothing; that it can be used to prove obvious falsehoods and therefore doesn’t necessarily track the truth; that it can be used to prove the truth of contingent, empirically obvious falsehoods when, since it is necessary a prior that one ought to be moral, something can be a good argument for the rationality of morality only if the argument’s style would entail only truths necessary a priori; that Sterba’s argument cannot inherit plausibility from what Sterba describes as the decision theoretic idea that when choosing among options where we have no evidence that one is more appropriate than the other, we must treat them as equally choice-worthy, since there is no such idea in decision theory, and shouldn’t be (for when, for example, there is no evidence that x exists and no evidence that x does not exist, one should believe that x does not exist; one should not chose as if x’s existence and non-existence were equally likely); that Sterba’s argument style is not analogous to the compromise strategies recommended in bargaining theory, nor in negotiating situations (although it would profit Sterba to consider David Gauthier’s approach in seeking to demonstrate that morality is both a middle ground between egoism and altruism, and is rationally obligatory); that it is problematic to see egoistic and altruistic reasons as commensurable and therefore admitting of a middle ground, especially a unique middle ground; that in any case, egoistic and altruistic reasons are not exhaustive of the reasons there could be; that the only sense in which moving to middle ground results in the parties not begging the question against each other is that it means they would be agreeing with each other and therefore not holding positions against each other, whether question-beggingly or otherwise, a fact which offers neither any rationally compelling reason to move her position closer to that of the other (for how can the mere fact that if we agreed we wouldn’t be begging the question against each other be a reason to agree?); and that even if morality is both rationally obligatory and a middle ground between egoism and altruism, it won’t be in any interesting sense true that this holds because the alternative would be question-begging, which means that analyzing the basis of the rationality of morality as being found in this principle of argumentation theory misconceives the nature of morality.

David Gauthier argues that it can be rational to perform a non-maximizing cooperative act, since there are certain situations in which it is rational to adopt an intention to perform a non-maximizing cooperative act, and since if it is rational to adopt an intention to do something, then it is rational to do that thing. An important objection to this argument focuses on the move from the rationality of adopting intentions to the rationality of acting on them. Gregory Kavka (...) argues that there are other situations – involving deterrence rather than cooperation – in which it is rational to adopt an intention to perform an irrational retaliatory action, that these situations and the cooperative ones are relevantly similar, so that, in the original cooperative situations, it is rational to adopt an intention to cooperate but irrational actually to cooperate. In this paper, I examine one way in which the argument for cooperation may be reformulated to circumvent this particular objection. (shrink)

Contractarians view justice as being defined by a contract made by rational individuals. No one supposes that this contract is actual, and the fact that it is merely hypothetical raises a number of questions both about the assumptions under which it would be actual and about the force of hypothetical agreement that is contingent on these assumptions.Particular contractarian theories must specify the circumstances of the agreement and the endowments, beliefs, desires, and degree and type of rationality of the agents. How (...) these issues are settled determines the force of the hypothetical agreement. The fact that ignorant people who desired only universal suffering would, under duress, agree to a certain principle gives us no reason to believe the principle is a correct moral principle or to think it rational to accept or act on it: some counterfactual assumptions undermine entirely the moral force of hypothetical agreement. On the other hand, to take people just as they are, with their current beliefs, desires, endowments, and all, is to endorse their ignorance and mistakes as well as any previous injustice that affects their bargaining power.

A powerful objection against moral conventionalism says that it gives the wrong reasons for individual rights and duties. The reason why I must not break my promise to you, for example, should lie in the damage to you—rather than to the practice of promising or to all other participants in that practice. Common targets of this objection include the theories of Hobbes, Gauthier, Hooker, Binmore, and Rawls. I argue that the conventionalism of these theories is superficial; genuinely conventionalist theories (...) are not vulnerable to the objection; and genuine moral conventionalism is independently plausible.

In a Star Trek: The Next Generation episode, Cpt. Picard is captured and trapped on a planet with an alien captain who speaks a language incompatible with the universal translator, based on their societal historical metaphors. According to Shapiro (2004), the concept of a universal translator removes everything alien from alien languages, and since the Tamarian language refers only to their historical and cultural archetypes, Picard can only establish dialogue by invoking human analogues, such as Gilgamesh. The purpose (...) of this paper is threefold. First, we will tie such communication to standard cognitive models in cognitive linguistics, pioneered by Lakoff and Johnson (1980) and Lakoff (1987). Second, we will show that metaphorical imaging resembling the Tamarian language is already present in our culture, by analyzing Dawkins's (1982) notion of a meme, who presupposes that memes as cultural living structures physically reside in the brain, and comparing that to a common format of a meme in pop culture. We will also contrast this concept with living natural languages such as Wolaytta, using a great number of proverbs, which can be seen as desemanticized metaphors that are used to embody different domains of the social realm of life (Make et al. 2014). Third, we will compare the notion of such a language with the current state of machine-learning and deep-learning techniques for natural language processing of metaphorical phrases, pinpointing that even deep learning today is powerless without sufficient training datasets (cf. Perifanos et al. 2020) or specific known word contexts and embeddings (Rei et al. 2017), compared to the same situation the universal translator was faced with when dealing with the Tamarian language.

To the normal reasons that we think can justify one in preferring something, x (namely, that x has objectively preferable properties, or has properties that one prefers things to have, or that x's obtaining would advance one's preferences), I argue that it can be a justifying reason to prefer x that one's very preferring of x would advance one's preferences. Here, one prefers x not because of the properties of x, but because of the properties of one's having the preference (...) for x. So-revising one's preferences is rational in paradoxical choice situations like Kavka's Deterrence Paradox. I then try to meet the following objections: that this is stoicist, incoherent, bad faith; that it conflates instrumental and intrinsic value, gives wrong solutions to the problems presented by paradoxical choice situations, entails vicious regresses of value justification, falsifies value realism, makes valuing x unresponsive to x's properties, causes value conflict, conflicts with other standards of rationality, violates decision theory, counsels immorality, makes moral paradox, treats value change as voluntary, conflates first- and second-order values, is psychologically unrealistic, and wrongly presumes that paradoxical choice situations can even occur.

The thesis that rationality consists in the straight-forward maximization of utility has not lacked critics. Typically, however, detractors reject the Humean picture of rationality upon which it seems based; they seek to emancipate reason from the tyranny of the passions. It is, then, noteworthy when an attack on this thesis comes from ‘within the ranks.’David Gauthier's paper ‘Reason and Maximization’ is just such an attack; and for this reason, among others, it is interesting. It is not successful, though. In (...) defense of this conclusion, we shall begin by relating the essentials of Gauthier's argument. Then we shall examine in some detail Gauthier's claim that the principle of straighforward max-imization fails to be self-supporting. We shall argue that Gauthier's defense of this claim is at best incomplete. Finally, we shall show that the fact that a normative principle is self-subverting or non-self-supporting does not entail that the principle is defective. (shrink)

A book chapter (about 4,000 words, plus references) on decision theory in moral philosophy, with particular attention to uses of decision theory in specifying the contents of moral principles (e.g., expected-value forms of act and rule utilitarianism), uses of decision theory in arguing in support of moral principles (e.g., the hypothetical-choice arguments of Harsanyi and Rawls), and attempts to derive morality from rationality (e.g., the views of Gauthier and McClennen).

In this article author contrasts possibilism (the view that art is about the logically possible and that it cannot be about the impossible) with impos- sibilism (the view that art can be and sometimes is about the logically impossible as well). Author argues in favor of possibilism. The main insight is that since impossible objects are necessarily non-existent art cannot be about them, it has to be about something that can exist. Also, author formulates five more detailed views about the (...) issue. Further, author discusses related notions like imaginability and conceivability. Author holds that Hume’s insight that an object cannot be conceived as non-existent counts in favour of possibilism. Besides, author introduces the distinction between real and apparent content of the work of art, believing that this distinction can be relevant in the discussion between possibilism and impossibilism. In the rest of the article author analyzes several prima facie counterexamples to possibilism (Jean-Luc Picard, Anna Karenina, paradox of patricide, Escher’s graphics) and tries to explain them away.

I illustrate the use of decision-theory and game-theory in the social sciences by means of examples from Gauthier, Tversky and Kahneman, and Bouldon.

The standard formulation of Newcomb's problem compares evidential and causal conceptions of expected utility, with those maximizing evidential expected utility tending to end up far richer. Thus, in a world in which agents face Newcomb problems, the evidential decision theorist might ask the causal decision theorist: "if you're so smart, why ain’cha rich?” Ultimately, however, the expected riches of evidential decision theorists in Newcomb problems do not vindicate their theory, because their success does not generalize. Consider a theory that allows (...) the agents who employ it to end up rich in worlds containing Newcomb problems and continues to outperform in other cases. This type of theory, which I call a “success-first” decision theory, is motivated by the desire to draw a tighter connection between rationality and success, rather than to support any particular account of expected utility. The primary aim of this paper is to provide a comprehensive justification of success-first decision theories as accounts of rational decision. I locate this justification in an experimental approach to decision theory supported by the aims of methodological naturalism. (shrink)

How may nations protect their interests in space if its fragility makes military operations there self-defeating? This essay claims nations are in Prisoners Dilemmas on the matter, and applies David Gauthier’s theories about how it is rational to behave morally—cooperatively—in such dilemmas. Currently space-faring nations should i) enter into co-operative space sharing arrangements with other rational nations, ii) exclude—militarily, but with only terrestrial force—nations irrational or existentially opposed to other nations being in space, and iii) incentivize all nations into (...) co-operation by redistributing some space-generated wealth to nations that might otherwise ruin space. Further, since all nations are rationally incentivized to ever greater dependence on space, and since each, by threatening space, can hold hostage its benefits to all, each can demand resolution of terrestrial discontents with other nations. So each has a rational interest in treating others morally both in space and on terrestrial issues. (shrink)

In 1951 John Rawls expressed these convictions about the fundamental issues in metaethics: [T]he objectivity or the subjectivity of moral knowledge turns, not on the question whether ideal value entities exist or whether moral judgments are caused by emotions or whether there is a variety of moral codes the world over, but simply on the question: does there exist a reasonable method for validating and invalidating given or proposed moral rules and those decisions made on the basis of them? For (...) to say of scientific knowledge that it is objective is to say that the propositions expressed therein may be evidenced to be true by a reasonable and reliable method, that is, by the rules and procedures of what we may call "inductive logic"; and, similarly, to establish the objectivity of moral rules, and the decisions based upon them, we must exhibit the decision procedure, which can be shown to be both reasonable and reliable, at least in some cases, for deciding between moral rules and lines of conduct consequent to them.1 In this passage Rawls reconfigured the issue of moral objectivity and so reoriented the practice of metaethics from linguistic analysis to rational methodology. In so doing, his work has provided inspiration to philosophers as disparate in normative views as Thomas Nagel,2 Richard Brandt3, Alan Gewirth4, and David Gauthier.5 Rawls replaced the Moorean question, Do moral terms refer? with the Rawlsian question, Can moral judgments be the outcome of a rational and reliable procedure? He later gave a resoundingly positive answer to this question6 and later still, a more tentative one.7 Rawls' considered qualification of his earlier enthusiasm about the extent to which moral philosophy could be "part of the theory of rational choice"8 is a tribute to the seriousness with which he took his critics' objections.

Till just few decades ago, scholars used to use the label ‘Ockhamism’ to mark a turning-point in the history of mediaeval philosophy, above all in the history of natural philosophy. That turning-point was exemplified by the once so-called ‘Buridanian school’, today known simply as ‘Parisian school of natural philosophy’, whose leading representative was for sure John Buridan. But looking carefully at some crucial points of the Picard master’s idea of ‘nature’, concerning specifically the relationship between God and secondary causes (...) on one side, and the role played by free will, both the divine and the human one, on the other side, one will find out that Buridan’s ‘Ockhamism’ is at least questionable: Scotus’ modal logic is the conceptual framework, within which he redetermines the boundaries of natural laws, but the ‘pure ockhamist’ idea of the prevalence of the will on the intellect in God’s nature is the source of an image of the world in which voluntary behaviours and natural laws are intertwined. Therefore, Buridan’s natural philosophy results as a peculiar synthesis of two of the main divergent lines of thinking of late mediaeval philosophy. (shrink)

TWENTIETH-CENTURY ETHICS. AFTER NIETZSCHE -/- Preface This book tells the story of twentieth-century ethics or, in more detail, it reconstructs the history of a discussion on the foundations of ethics which had a start with Nietzsche and Sidgwick, the leading proponents of late-nineteenth-century moral scepticism. During the first half of the century, the prevailing trends tended to exclude the possibility of normative ethics. On the Continent, the trend was to transform ethics into a philosophy of existence whose self-appointed task was (...) that of describing the human condition as consisting of choices, as unavoidable as arbitrary, without any attempt at providing criteria for making such choices. In the Anglo-Saxon countries, the heir of ethics was a philosophy of morality, that is, an analysis of the language of morality that intended to clarify valuations without trying to justify them. 1958 was the year of the normative turn that led to the Rehabilitation of practical philosophy, a turn followed by decades of controversies between distinct kinds of normative ethics: utilitarian, Kantian, virtue ethics. While the controversy was raging, a quiet revolution took place, that of applied ethics which surprisingly dissolved the controversy's very subject matter by providing methods for making convergence possible on intermediate principles even when no agreement was available about first principles. The normative turn and the revolution of applied ethics have led us, at the turn of the century, to a goal that was quite far from the starting point. Instead of scepticism and relativism that was the fashion at the beginning of the century, at the beginning of the third millennium impartial and universal moral arguments seem to hold the spot being supported, if not by a final rational foundation, at least by reasonableness, the most precious legacy of the Enlightenment. -/- ● TABLE OF CONTENTS -/- ● I Anglo-Saxon philosophy: naturalism 1.

Stevenson and the pragmatics of moral language 6. Stevenson and the methods for solving ethical disagreement 7. Hare and prescriptivism The chapter reconstructs first the discussion after Moore. The naturalistic-fallacy argument was widely accepted but twisted to prove instead that the intuitive character of the definition of 'good', its non-cognitive meaning, in a first phase identified with 'emotive' meaning. Alfred Julius Ayer is indicated as a typical proponent of such non-cognitivist meta-ethics. More detailed discussion is dedicated to Bertrand Russell's ethics, a more nuanced and sophisticated doctrine, arguing that non-cognitivism does not condemn morality to arbitrariness and that the project of rational normative ethics is still possible, heading finally to the justification of a kind of non-hedonist utilitarianism. Stevenson's theory, another moderate version of emotivism is discussed at some length, showing how the author comes close to the discovery of the role of a pragmatic dimension of language as a basis for ethical argument. A section reconstructs the discussion from the Forties about Hume's law, mentioning Karl Popper's argument and Richard Hare's early non-cognitivist but non-emotivist doctrine named prescriptivism. -/- ●IV Anglo-Saxon philosophy: critics of non-cognitivism 1.

Reinach and the theory of social acts 4. Scheler and the material ethics of values 5. Hartmann and the ontology of values 6. Plessner, Gehlen and the Philosophische Anthropologie -/- The chapter illustrates first the idea of phenomenology and the Husserl's project of a phenomenological ethic as illustrated in his 1908-1914 lectures. The key idea is dismissing psychology and trying to ground a new science of the apriori of action, within which a more restricted field of inquiry will be the science of right actions. Then the chapter illustrates the criticism of modern moral philosophy conducted in the 1920 lectures, where the main target is naturalism, understood in the Kantian meaning of primacy of common sense. The third point illustrate is Adolph Reinach's theory of social acts as a key the grounding of norms, a view that sketches the ideas 'discovered' later by Clarence I. Lewis, John Searle, Karl-Otto Apel and Jürgen Habermas. A final section discusses Nicolai Hartman, who always refused to define himself a phenomenologist and yet developed a more articulated and detailed theory of 'values' – with surprising affinities with George E. Moore - than philosophers such as Max Scheler, who claimed to be Husserl's legitimate heirs. -/- ● VI Continental philosophy: the critics of the philosophy of values 1.

The discussion on act and rule utilitarianism 2. Hare on two-tiered preference utilitarianism 3. Harsanyi, Gauthier and rational choice ethics 4. Parfit, utilitarianism and the idea of a person 5. Brandt and indirect conscience utilitarianism -/- The chapter addresses the issue of the complex process of self-transformation Utilitarianism underwent after Sidgwick's and Moore's fatal criticism and the unexpected Phoenix-like process of rebirth of a doctrine refuted. Two examples give the reader a glimpse at this uproarious process. The first is Roy Harrod Wittgensteinian transformation of utilitarianism in pure normative ethics depurated from hedonism as well as from whatsoever theory of the good. This transformation results in preference utilitarianism combined with a 'Kantian' version of rule utilitarianism. The second is Richard Hare's two-level preference utilitarianism, where act utilitarianism plays the function of the eventual rational justification of moral judgments and rule-utilitarianism that of an action-guiding practical device. -/- ● IX Normative ethics: neo-Aristotelianism and virtue ethics 1. Hannah Arendt, action and judgement 2. Hans-Georg Gadamer and phronesis 3. Alasdair MacIntyre on practices, virtues, and traditions 5. Stuart Hampshire on deliberation 6. Bernard Williams and moral complexity 7. Feminist ethics -/- Sect 1 reconstructs the post-war rediscovery of ethics by many German thinkers and its culmination in the Sixties in the movement named 'Rehabilitation of practical philosophy' is described. Heidegger's most brilliant disciples were the promoters of this Rehabilitation. Hans-Georg Gadamer is a paradigmatic example. His reading of Aristotle's lesson I reconstructed, starting with Heidegger's lesson but then subtly subverting its outcome thanks to the recovery of the significant role of the notion of phronesis. Sect 3 discusses the three theses defended by Anscombe in 'Modern Moral Philosophy'. It argues that: a) her answer to the question "why should I be moral?" requires a solution of the problem of theodicy, and ignores any attempts to save the moral point of view without recourse to divine retribution; b) her notion of divine law is an odd one more neo-Augustinian than Biblical or Scholastic; c) her image of Kantian ethics and intuitionism is the impoverished image manufactured by consequentialist opponents for polemical purposes and that she seems strangely accept it; d) the difficulty of identifying the "relevant descriptions" of acts is not an argument in favour of an ethics of virtue and against consequentialism or Kantian ethics, and indeed the role of judgment in the latter is a response to the difficulties raised by the case of judgment concerning future action. The chapter gives a short look at further developments in the neo-naturalist current trough a reconstruction of Philippa Foot's and Peter Geach's critiques to the naturalist-fallacy argument and Alasdair MacIntyre's grand reconstruction of the origins and allegedly inevitable failure of the Enlightenment project of an autonomous ethic. -/- ● X Normative ethics: Kantian and rights-based ethics 1. Dialogical constructivism 2. Apel, Habermas and discourse ethics 3. Gewirth and rights-based ethics 4. Nagel on agent-relative reasons 5. Donagan and persons as ends in themselves Parallel to the neo-Aristotelian trend, there was in the Rehabilitation of practical philosophy a Kantian current. This current started with the discovery of the pragmatic dimension of language carried out by Charles Peirce and the Oxford linguistic philosophy. On this basis, Karl-Otto Apel singled out as the decisive proponent of the linguistic and Kantian turn in German-speaking ethics, worked out the performative-contradiction argument while claiming that this was able to provide a new rational and universal basis for normative ethics. The chapter offers an examination of his argument in some detail, followed by a more cursory reconstruction of Jürgen Habermas's elaboration on Apel's theory. -/- ● XI The applied ethics renaissance 1. Elisabeth Anscombe on the atom bomb 2. From medical ethics to bioethics 3. Rawls and public ethics 3. Nozick, Dworkin and further developments of public ethics 5. Sen and the revival of economic ethics -/- The chapter presents the revolution of applied ethics while stressing its methodological novelty, exemplified primarily by Beauchamp and Childress principles approach and then by Jonsen and Toulmin's new casuistry. The chapter argues that Rawls's distinction between a "political" and a "metaphysical" approach to the theory of justice, one central part of ethical theory, is a formulation of the same basic idea at the root of both the principles approach and the new casuistry, both discussed in the following chapter. The idea is that it is possible to reach an agreement concerning positive moral judgments even though the discussion is still open – and in Rawls' view never will be close – on the essential criteria for judgment. -/- ● XII Fin-de-siècle metaethics 1. Deontic logics 2. Anti-realism 3. External realism 4. Internal realism 5. Kantian constructivism -/- The chapter illustrates the fresh start of meta-ethical discussion in the Eighties and Nineties and the resulting new alignments: metaphysical naturalism, internal realism, anti-realism, and constructivism.

In the attempt of defending an interpretation of David Hume's moral and political philosophy connected to classical utilitarianism, intervenes in a key way the so called problem of the " Sensitive Knave " raised by this author at the end of his more utilitarian work, the Enquiry Concerning the Principles of Morals. According to the classic interpretation of this fragment, the utilitarian rationality in politics would clash with morality turning useless the latter. Therefore, in the political area the defense of (...) a moral utilitarianism would be an auto contradictory task. In order to show that, first, Hume does not say anything similar to this and second, that even indicates the way of overcoming this apparent contradiction between morality and rationality, we analyze briefly the arguments from which there comes basically this "anti-utilitarian" standard interpretation, and we defend an interpretation of the humean discussion on the problem of the supposed conflict between morality and rationality, or of rational incentives for immoral behavior, which allows to explain better Hume's position on this problem. Finally, we propose an instance of overcoming the contradiction morality/ rationality by a rule adjusted utilitarianism centered on the idea of the "progressive development of artificial institutions of reinforcement of morality", that Hume himself would suggest in other places in which he approaches the topic of the apparent contradiction between "morality" and "knavery". We propose also possible lines of future development of this idea, between them its use to clarify the relation of David Hume's thought with certain forms of contemporary liberalism. (shrink)

The author examines Hobbes and Hume in the light of recent proposals of neo-Hobbesian political theories. Magri concludes that Hobbes and Hume's strategies would be plausible from the point of view of liberal thinking if they succeeded; the difficulty, however, is that both systems fail to overcome the barrier between individual interests and moral and political principles.

I discuss what learned and innate routines of self and other attribution agents need to possess if they are to enter into cooperative arrangements as described game theoretically. I conclude that these are not so different from belief desire psychology as described by philosophers of mind.
