This paper examines the conceptual development of the philosophical justifications for tyrannicide. It posits that the political philosophy of tyrannicide can be categorised into three distinct periods or models, the classical, medieval, and liberal, respectively. It argues that each model contained unique themes and principles that justified tyrannicide in that period; the classical, through the importance attached to public life and the functional role of leadership; the medieval, through natural law doctrine; and the liberal, through the postulates of social contract (...) theory. Subsequent analysis of these different models however, reveals that these historical models are unable to provide a sufficient philosophical basis for a contemporary justification of tyrannicide. In Part II, it will be contended that a reinvigorated conception of self-defence, a theme common to all three models, when coupled with the modern notion of universal human rights, may provide the foundation for a contemporary theory of tyrannicide.

This is the final part of a series of two papers that have examined the conceptual development of the philosophical justifications for tyrannicide. While Part I focused on the classical, medieval, and liberal justifications for tyrannicide, Part II aims to provide the tentative outlines of a contemporary model of tyrannicide in world politics. It is contended that a reinvigorated conception of self-defence, when coupled with the modern understanding of universal human rights, may provide the foundation for the normative validity of (...) tyrannicide in contemporary world politics.

Conversational contextualism in epistemology is characterized by four main theses: 1. the indexicality of knowledge claims thesis; 2. the attributor contextualism thesis; 3. the conversational contextualism thesis, and 4. the main thesis of contextualism according to which a knowledge claim can be true in one context and false in another context in which more stringent standards for knowledge are operant. It is argued that these theses taken together generate problems for contextualism. In particular, it is shown that there is no (...) context in which the contextualist can truthfully claim to know her theory is true. Since these results were obtained only with principles the contextualist cannot give up—like the principle of epistemic closure and the principle that knowledge implies truth—it seems that contextualism is in need of a thoroughgoing revision if it is to become a successful epistemic theory.

Patients may show a more-or-less complete deviation of the head and eyes towards the right (ipsilesional) side [that is, to the same side of egocentric space as the brain lesion responsible for their disorder]. If addressed by the examiner from the left (contralesional) side [the opposite side to their lesion], patients with severe extrapersonal neglect may fail to respond or may look for the speaker in the right side of the room, turning head and eyes more and more to the (...) right. Frequently these patients will not pick up food from the left half of the plate. Given a crossword puzzle, they may complete only the squares to the right. If walking is not prevented by hemiparesis, neglect patients may lose their bearings, since they do not make use of left sided cues. (shrink)

Locating the history of male honour in the perspective of his philosophical anthropology, Mandeville is able to show that the rituals of modern honour are an exemplary expression of that spontaneous, artificial order stemming out of a natural disposition of human passions. For Mandeville, duelling provides decisive evidence that the desire for approval from others, even at the cost of one's life, is a dominant motive in man's behaviour. The aim of this paper is to review selected Scottish responses to (...) the questions raised by Mandeville's views on ‘Modern Honour’ and his provocative defense of duelling. (shrink)

This paper presents an argument for reconceptualizing (human) intelligence as intellectual virtue, and makes some proposals as to how we would understand intellectual virtue if feminist values were taken into account. Several abilities are identified which are closely connected to one aim that is common to most feminists: the building of communities in which well-being is possible.

Smith's famous invocation of the invisible hand -according to which self-interest promotes the greater good — has popularly been seen as a fundamental challenge to business ethics, a field committed to the opposite premise that the public interest cannot be advanced unless economic egoism is restrained by a more socially conscious mindset, one that takes into account the legitimate needs of stakeholders and the reciprocity inherent in networked relationships. Adam Smith has been brought into the discipline to show that his (...) authority cannot be summoned to fully support the free market sceptics of business ethics. Little has been done, however, to illustrate that Smith's moral writings actually contain the fundamentals of a business ethics teaching for managers who necessarily work within a variety of networks. This article analyses his moral thought to infer a Smithean framework of business ethics for managers. Smith believes that self-interest should be subordinated to moral imperatives, even in the business world. However, Smith rejects the principles of corporate social responsibility on the argument that benevolent impulses cannot be expected to prevail in the commercial arena. Instead of consciously trying to advance the social good, Smith's ideal manager will endeavour to personally live up to the standards enforced by an impartial spectator of his conduct, a theoretical entity reflecting the ethical requirements posed by the manager's social networks and stakeholder relationships. While this internalized onlooker expects a limited degree of benevolence, the overriding demand is for the manager to abide by the dictums of justice and prudence. (shrink)

In this article, I discuss how Samuel Stanhope Smith advanced Reidian themes in his moral philosophy and examine their reception by Presbyterian revivalists Ashbel Green, Samuel Miller, and Archibald Alexander. Smith, seventh president and moral philosophy professor of the College of New Jersey (1779–1812), has received marginal scholarly attention regarding his moral philosophy and rational theology, in comparison to his predecessor John Witherspoon. As an early American philosopher who drew on the ideals of the Scottish Enlightenment including Common Sense philosophy, (...) Smith faced heightened scrutiny from American revivalists regarding the danger his epistemology presented to the institution of religion. The Scottish School of Common Sense was widely praised and applied in nineteenth-century American moral philosophy, but before the more general American acceptance of Common Sense, Smith already appealed to Reidian themes in his methodology and treatment of external sensations, internal sensations, intellectual powers, and active powers of the human mind. In this paper, I argue that Smith's use of Reidian themes for grooming his student's morality conflicted with the educational expectations from revivalists on Princeton's board of trustees who demanded more attention on orthodox theology. I identify Smith's notions of causation, liberty, and the moral faculty as primary reasons for this tension over Princeton's educational purpose during the first decade of the nineteenth century.

The central recommendation of this article is that philosophers trained in the analytic tradition ought to add the sensibilities and skills of the historian to their methodological toolkit. The value of an historical approach to strictly philosophical matters is illustrated by a case study focussing on the medieval origin of conceivability arguments and contemporary views of modality. It is shown that common metaphilosophical views about the nature of the philosophical enterprise as well as certain inference patterns found in thinkers from (...) Descartes to Chalmers have their origin in the theological concerns of the Scholastics. Since these assumptions and inference patterns are difficult to motivate when shorn of their original theological context, the upshot is that much post-Cartesian philosophy is cast in an altogether unfamiliar, and probably unwelcome, light. The methodological point, however, is that this philosophical gain is born of acquaintance with the history of ideas. (shrink)

After a brief review of the notions of necessity and a priority, this paper scrutinizes Kripke's arguments for supposedly contingent a priori propositions and necessary a posteriori propositions involving proper names, and reaches a negative conclusion, i.e. there are no such propositions, or at least the propositions Kripke gives as examples are not such propositions. All of us, including Kripke himself, still have to face the old question raised by Hume, i.e. how can we justify the necessity and universality of (...) general statements on the basis of sensory or empirical evidence?

In the the passage just quoted from the Dialogues concerning Natural Religion, David Hume developed a thought-experiment that contravened his better-known views about "chance" expressed in his Treatise and first Enquiry. For among other consequences of the 'eternal-recurrence' hypothesis Philo proposes in this passage, it may turn out that what the vulgar call cause is nothing but a secret and concealed chance. (In this sentence, I have simply reversed "cause" and "chance" in a well-known passage from Hume's Treatise, p. 130). (...) In the first eight sections of this essay, I develop one topological and model-theoretic analogue of Hume's thought-experiment, in which 'most' ('A-generic') models M of a 'scientific' theory U are both 'eternally recurrent' and topologically random (in a sense which will be made precise), even though they are 'inductively' defined, via a step-by-step ('empirical'?) procedure that Hume might have been inclined to endorse. The last aspect of this model-theoretic thought-experiment also serves to distinguish it from simpler measure-theoretic prototypes that are known to follow from Kolmogorov's Zero-One Law (cf. the Introduction, 5.2, 6.1 and 6.7 below). In the last three sections, I will argue more informally (1) that the metamathematical thought-experiments just mentioned do have a genuine metaphysical relevance, and that this relevance is predominantly skeptical in its implications; (2) that such 'nonstandard' instances of semantic underdetermination and 'pathology' seem to be the metatheoretic rule rather than the exception; and therefore, (3) that metamathematical and metatheoretic 'malign-genius' arguments are quite coherent, contrary (e.g.) to assertions such as that of Putnam (1980), pp. 7-8. In the essay's conclusion, finally, I assimilate (2) and (3) to the familiar datum that 'simplicity', rather than 'pathology', has more often than not turned out to be an anomalous 'special case' in the historical development of scientific and mathematical ontology.

The basic purpose of this essay, the first of an intended pair, is to interpret standard von Neumann quantum theory in a framework of iterated measure algebraic truth for mathematical (and thus mathematical-physical) assertions — a framework, that is, in which the truth-values for such assertions are elements of iterated boolean measure-algebras (cf. Sections 2.2.9, 5.2.1–5.2.6 and 5.3 below).The essay itself employs constructions of Takeuti's boolean-valued analysis (whose origins lay in work of Scott, Solovay, Krauss and others) to provide a (...) metamathematical interpretation of ideas sometimes considered disparate, heuristic, or simply ill-defined: the collapse of the wave function, for example; Everett's many worlds'-construal of quantum measurement; and a natural product space of contextual (nonlocal) hidden variables.

Gedächtnis-Enhancement oder Memory-Enhancement ist ein Teilbereich der verschiedenen Ansätze zur pharmakologischen und technischen Verbesserung menschlicher Leistungsfähigkeit. Wie Erfahrungsberichte von Menschen mit von Natur aus gesteigertem Erinnerungsvermögen zeigen, ist eine Steigerung der Gedächtnisfähigkeit prinzipiell möglich. Allerdings verweisen diese Erfahrungen auch auf einige Komplikationen und Beschwernisse infolge dieser gesteigerten Leistungsfähigkeit. Es wird argumentiert, dass erstens diejenigen philosophischen Theorien, die die Funktion des Gedächtnisses v. a. in der Speicherung von Informationen lokalisieren, einige dieser Probleme nicht antizipieren und nur unzulänglich erklären können. Zweitens wird (...) argumentiert, dass philosophische Konzepte zur Funktion von Erinnern und Vergessen, die deren Bedeutung bei der Bildung eines normativ geleiteten Selbstverständnisses in den Vordergrund stellen, diese und weitere mögliche Komplikationen deutlicher in den Blick bekommen können. Beispielhaft wird hier auf Ansätze von Ricoeur und Nietzsche eingegangen. (shrink)

This paper suggests and discusses an answer to the following question: What distinguishes causal from non-causal or coincidental co-occurrences? The answer derives from Elizabeth Anscombe’s idea that causality is a highly abstract concept whose meaning derives from our understanding of specific causally productive activities, and from her rejection of the assumption that causality can be informatively understood in terms of actual or counterfactual regularities.Keywords: Elizabeth Anscombe; Causality; Explanation; Inhibition.

This article explains how li 禮 or ‘ritual propriety’ is the ‘body language’ of ren 仁 or the authentic expression of our humanity. Li and ren are interdependent aspects of a larger creative human way (rendao 仁道) that can be conceptually distinguished as follows: li refers to the ritualized social form of appropriate conduct and ren to the more general, authentically human spirit this expresses. Li is the social instrument for self-cultivation and the vehicle of harmonious human interaction. More, li (...) must mean something that is effectively communicated to others for an authentic, human (ren) interaction to occur. Li is the body language of ren in being the ritual vehicle for its’ expression; however, li is underdetermined by ren and so must be distinguished from it in on further grounds: authentic human activity must not just be equivocated with social convention because conclusively establishing whether a particular action is li (or is a truly ren action) is impossible. As a result, li is often confused with social power and privilege that is easier to empirically identify than ren conduct is, but this is a mistake since li has to express ren or it is not li at all. The inescapable ambiguity of li – an ambiguity that attaches to any language – can be critiqued by the Western view that sees something ‘essential’ to the ‘self,’ and that makes one a ‘self’ in and of oneself and not in a way that depends on others. I show that such Western individualism – while resting on a fundamentally different way of thinking of being a person and living a good life – does not reduce Confucian ritual to being an instrument for social discrimination and subordination. My argument is indebted to twentieth-century philosophy of language in the West that offered the idea that some words are actions. (shrink)

Scientific psychology involves both identifying and classifying phenomena of interest (description) and revealing the causes and mechanisms that contribute towards these phenomena arising (explanation). Within personality psychology, some propose that aspects of behavior and cognition can be explained with reference to personality traits. However, certain conceptual and logical issues cast doubt upon the adequacy of traits as coherent explanatory constructs. This paper discusses ?explanation? in psychology and the problems of circularity and reification. An analysis of relations and intrinsic properties is (...) then developed to address the logical requirements necessary for circumventing these problems. An examination of McCrae and Costa's defense of traits as explanatory constructs, in terms of ?tendencies? and ?dispositions? highlights logical issues that prevent traits, so defined, from explaining trait-like behaviors and cognitions. The logical requirements for a coherent trait-explanatory account are outlined and possible explanatory directions in trait-approaches are discussed. The ongoing tendency towards fallacious reasoning in psychology and suggestions for preventing this are further examined. (shrink)

I offer a reply to criticisms of the Strong Programme presented by Stephen Kemp who develops some new lines of argument that focus on the ‘monism’ of the programme. He says the programme should be rejected for three reasons. First, because it embodies ‘weak idealism’, that is, its supporters effectively sever the link between language and the world. Second, it challenges the reasons that scientists offer in explanation of their own beliefs. Third, it destroys the distinction between successful and unsuccessful (...) instrumental action. Kemp is careful to produce quotations from the supporters of the programme as evidence to support his case. All three points deserve and are given a detailed response and the interpretation of the quoted material plays a significant role in the discussion. My hope is that careful exegesis will offset the numerous misinterpretations that are current in the philosophical literature. Particular attention is paid to what is said about the normative standards involved in the application of empirical concepts. The operation of these standards in the face of the negotiability of all concepts is explored and misapprehensions on the topic are corrected. The work of Wittgenstein, Popper, Kuhn and Hesse is used to illustrate these themes.Keywords: Strong Programme; Social constructionism; Idealism; Monism; Finitism; Relativism. (shrink)

The question, “What norms are appropriate for the evaluation of the probative merits of visual arguments?” underlies the investigation of this paper. The notions of argument and of multimodal visual argument employed in the study are explained. Then four multimodal visual arguments are analyzed and their probative merits assessed. It turns out to be possible to judge these qualities using the same criteria that apply to verbally expressed arguments. Since the sample is small and not claimed to be representative, this (...) finding can at best be regarded as suggestive for the probative assessment of multimodal visual arguments in general.

In my article I summarize a 'Humean' view of deliberation, and in particular deliberation with an ethical aspect. I regard Hume as having paved the way for a 'naturalistic' account of these things, avoiding Kantian fantasies of agency that dominate much current work. Contrary to what is often supposed, the Humean story gives a satisfactory account of dutiful or principled motivations, and a rich account of the ways in which different aspects of character are selected as 'useful or agreeable to (...) ourselves or others'.

In this paper I explore the points of similarity and difference that distinguish expressivists such as myself from the position known as Cornell realism. I argue that there are considerable overlaps of doctrine, although these doctrines are arrived at in very different ways. I urge that Cornell realism can only benefit by taking on some of the commitments of expressivism.

Abstract In Peirce's and Hanson's characterization of abductive inference, the abducted hypothesis (but not others) is present in the premises, so that the inference can hardly be taken as ampliative. Abduction has consequently been treated as part of the process whereby already generated hypotheses are judged in terms of their plausibility, simplicity, etc. I propose an interpretation of abduction which supports an ampliative view. It relies on a distinction between two logical stages in the generation of hypotheses, one ?factual? and (...) one ?explanatory?. I also indicate how we may reconstruct Peirce's and Hanson's original inference in an ampliative form. (shrink)

This paper attempts to analyze the concept of quantum statistical determinism. This is done after we have clarified the epistemic difference between causality and determinism and discussed the content of classical forms of determinism—mechanical and dynamical. Quantum statistical determinism transcends the classical forms, for it expresses the multiple potentialities of quantum systems. The whole argument is consistent with a statistical interpretation of quantum mechanics.

A shift from a metaphysical framework of substance to one of process enables an integrated account of the emergence of normative phenomena. I show how substance assumptions block genuine ontological emergence, especially the emergence of normativity, and how a process framework permits a thermodynamic-based account of normative emergence. The focus is on two foundational forms of normativity, that of normative function and of representation as emergent in a particular kind of function. This process model of representation, called interactivism, compels changes (...) in many related domains. The discussion ends with brief attention to three domains in which changes are induced by the representational model: perception, learning, and language. (shrink)

This paper argues that history differs from natural science in relying on folk psychology and so narrative explanations. In narratives, actions, beliefs, and pro-attitudes are joined by conditional and volitional connections. Conditional connections exist when beliefs and pro-attitudes pick up themes from one another Volitional connections exist when agents command themselves to do something having decided to do it because of a pro-attitude they hold. The paper defends the epistemic legitimacy of narratives by arguing we have legitimate grounds for postulating (...) conditional and volitional connections since they are given to us by a folk psychology we accept as true.

In recent years, there has been considerable debate in the literature concerning the existence of moral character. One lesson we should take away from these debates is that the concept of character, and the role it plays in guiding our actions, is far more complex than most of us initially took it to be. Just as Gilbert Harman, for example, makes a serious mistake in insisting, plainly and simply, that ther is no such thing as character, defenders of character also (...) make a mistake to the extent that they imply there is no problem raised by the psychological literature for either the concept of character or the nature of character-based ethics. My hope for this paper is to avoid both of these mistakes by first, exploring exactly what is the concept of character that is so firmly rooted in our philosophical and everyday thinking; and second, exploring the implications of the psychological literature for this appropriately understood concept of character. In so doing, I will come to a resolution that vindicates the existence of character, while at the same time calls attention to the real and serious problem suggested by the psychological evidence. This, we will see, is a problem of moral motivation. (shrink)

According to a traditional view, perceptual experiences are composites of distinct sensory and cognitive components. This dual-component theory has many benefits; in particular, it purports to offer a way forward in the debate over what kinds of properties perceptual experiences represent. On this kind of view, the issue reduces to the questions of what the sensory and cognitive components respectively represent. Here, I focus on the former topic. I propose a theory of the contents of the sensory aspects of perceptual (...) experience that provides clear criteria for identifying what kinds of properties they represent. (shrink)

This paper aims at specifying the complex links which two major and polemically related 18th-century linguistic theories James Harris' universal grammar in Hermes (1751) and John Horne Tooke's system of etymology in the Diversions of Purley (1786, 1804) bear to empiricism. It describes both the ideologicalethical determining factors of the theories and the epistemological consequences dependent upon their respective philosophical orientation (Harris using classical Greek philosophy against empiricism, Tooke criticizing Locke's semantics along Hobbesian lines). The effects within the linguistic theories (...) are examined through a comparison of the theories of determination which follow from divergent theses concerning abstraction. The analysis proposed in this paper exemplifies once more the historical question of the exact location of the compatibility/incompatibility between empiricist and non-empiricist linguistic theories.

A recalcitrant emotion is an emotion that we experience despite a judgment that seems to conflict with it. Having been bitten by a dog in her childhood, Jane cannot shake her fear of dogs, including Fido, the cute little puppy that she knows to be in no way dangerous. There is something puzzling about recalcitrant emotions, which appear to defy the putatively robust connection between emotions and judgments. If Jane really believes that Fido cannot harm her, what is she afraid (...) of? This article seeks to show how recalcitrant emotion is possible. I argue that reductive theories that identify emotions with judgments, desires, or some combination thereof, cannot explain the possibility of emotional irrationality without contradiction. I then show that the appeal to sui generis attitudes also fails to solve the puzzle of recalcitrant emotions, and diagnose this failure as stemming from a misleading analogy between emotions and perceptions, and in particular, between recalcitrant emotions and perceptual illusions. The solution can be found in a different analogy: between emotions and actions; more specifically, between recalcitrant emotions and weakness of the will, akrasia. Like akratic actions, recalcitrant emotions entail responding to reasons, but to inferior reasons. Irrational but non-contradictory emotions are possible just as weakness of will is possible.

The search for the essence of emotions is a common feature of various views of emotions—many of which attempt to reduce emotions to one central component. Three major views that seek to define emotions via a basic component are: that emotions are essentially a cognitive-evaluative state; that emotions are feelings; that emotions are desires. I believe that all these reductions are inadequate. I focus here on as expressed in Nussbaum’s recent view of emotions. I begin, however, by briefly discussing and.

Fifty papers have been selected from the thirteen conferences and each of them is described in a short subsection individually written by one of the 24 authors. These subsections attempt to place the paper discussed in the context of the development of AI and Law, while often offering some personal reactions and reflections.

One of the advantages of my account in the essay “Instantiation as Partial Identity” was capturing the contingency of instantiation—something David Armstrong gave up in his experiment with a similar view. What made the contingency possible for me was my own non-standard account of identity, complete with the apparatus of counts and aspects. The need remains to lift some obscurity from the account in order to display its virtues to greater advantage. To that end, I propose to respond to those (...) who have grappled with it in print. There are various criticisms by commentators: that it is rendered absurd by the transitivity of identity, that it makes instantiation necessary instead of contingent, that it is unclear what counts are, that aspects are simply tropes, that my view does not capture multiple location, that I make an unclear reference to a theory of composition as identity, that the account suffers from problems with polyadicity, and that it is not a realist account of universals after all. I give responses to these objections. (shrink)

An actual cause of some token effect is itself a token event that helped to bring about that effect. The notion of an actual cause is different from that of a potential cause – for example a pre-empted backup – which had the capacity to bring about the effect, but which wasn't in fact operative on the occasion in question. Sometimes actual causes are also distinguished from mere background conditions: as when we judge that the struck match was a cause (...) of the fire, while the presence of oxygen was merely part of the relevant background against which the struck match operated. Actual causation is also to be distinguished from type causation: actual causation holds between token events in a particular, concrete scenario; type causation, by contrast, holds between event kinds in scenario kinds.

ABSTRACTWe seem to have a direct experience of our freedom when we act. Many philosophers take this feeling of freedom as evidence that we possess libertarian free will. Spinoza denies that we have free will of any sort, although he admits that we nonetheless feel free. Commentators often attribute to him what I call the ‘Negative Account’ of the feeling: it results from the fact that we are conscious of our actions but ignorant of their causes. I argue that the (...) Negative Account is flawed. The feeling of freedom also depends on a vacillation of the mind. When the mind forms too many incompatible associations, it vacillates between them. When we act, the mind vacillates back and forth between the kinds of actions that we associate with our present mental state. We then mistake this subjective vacillation for an objective feature of ourselves—namely, the power to do otherwise. (shrink)

This article examines Russell Hardin's interpretation of Hume's argument that great social order depends on coordination convention. The main argument shows that despite an apparent move in that direction Hume's main argument is that justice and the other convention-based virtues rest on a cooperative convention which solves a prisoner's dilemma problem and that states are required when a society exceeds some small size because only states can solve the large number prisoner's dilemma problems that constitute the 'problem of social order'. (...) In this Hume's argument is indebted to the original form of this argument found in Hobbes's Leviathan. (shrink)

Computer simulations are widely used in current scientific practice, as a tool to obtain information about various phenomena. Scientists accordingly rely on the outputs of computer simulations to make statements about the empirical world. In that sense, simulations seem to enable scientists to acquire empirical knowledge. The aim of this paper is to assess whether computer simulations actually allow for the production of empirical knowledge, and how. It provides an epistemological analysis of present-day empirical science, to which the traditional epistemological (...) categories cannot apply in any simple way. Our strategy consists in acknowledging the complexity of scientific practice, and trying to assess its rationality. Hence, while we are careful not to abstract away from the details of scientific practice, our approach is not strictly descriptive: our goal is to state in what conditions empirical science can rely on computer simulations. In order to do so, we need to adopt a renewed epistemological framework, whose categories would enable us to give a finer-grained, and better-fitted analysis of the rationality of scientific practice.
