As a non-cognitivist analysis of moral language, Charles Stevenson's sophisticated emotivism is widely regarded by moral philosophers as a substantial improvement over its historical antecedent, radical emotivism. None the less, it has come in for its share of criticism. In this essay, Leslie Allan responds to the key philosophical objections to Stevenson's thesis, arguing that the criticisms levelled against his meta-ethical theory rest largely on a too hasty reading of his works.

The aim of this paper is to reconstruct Charles L. Stevenson’s metaethical view. Since his metaethical view is a form of emotivism, I will start by explaining what the core claims of emotivism are. I will then explore and comment on the specific claims of Stevenson’s proposal. Last, I will offer an overview of the objections that have traditionally been raised against emotivism.

There is more to science than Aristotle’s natural desire to know. The major achievement of this book lies in presenting this idea through the study of the lives of various scientists.

It is commonly assumed that the non-cognitivists of the first half of the twentieth century - the emotivists – were internalists about moral motivation. It is also commonly assumed that they were prompted to choose emotivism over other cognitivist positions in ethics because of their commitment to internalism. Finally, it is also commonly assumed that they used an internalist argument to argue for emotivism. -/- In this article I argue that the connection between emotivism and internalism is far more tenuous (...) than is commonly assumed. I focus on two of the most important and influential emotivists: A. J. Ayer and Charles L. Stevenson. While it is true that Stevenson was an internalist, Ayer refused to endorse internalism. Neither of them was originally prompted to choose emotivism over cognitivist positions in ethics by internalist considerations. Finally, Ayer never used an internalist argument to argue for emotivism; Stevenson did once borrow an internalist argument from another philosopher in order to argue for emotivism, but he later abandoned it.

In his Philosophical Inquiry concerning Human Liberty (1717), the English deist Anthony Collins proposed a complete determinist account of the human mind and action, partly inspired by his mentor Locke, but also by elements from Bayle, Leibniz and other Continental sources. It is a determinism which does not neglect the question of the specific status of the mind but rather seeks to provide a causal account of mental activity and volition in particular; it is a ‘volitional determinism’. Some decades later, (...) Diderot articulates a very similar determinism, which seeks to recognize the existence of “causes proper to man” (as he says in the Réfutation d’Helvétius). The difference with Collins is that now biological factors are being taken into account. Obviously both the ‘volitional’ and the ‘biological’ forms of determinism are noteworthy inasmuch as they change our picture of the nature of determinism itself, but my interest here is to compare these two determinist arguments, both of which are broadly Spinozist in nature – and as such belong to what Jonathan Israel called in his recent book “the radical Enlightenment,” i.e. a kind of underground Enlightenment constituted by Spinozism – and to see how Collins’ specifically psychological vision and Diderot’s specifically biological vision correspond to their two separate national contexts: determinism in France in the mid-1750s was a much more medico-biological affair than English determinism, which appears to be on a ‘path’ leading to Mill and associationist psychology.

Two prevalent assumptions in the philosophy of sport literature are that all sports are games and that all games are contests, meant to determine who is the better at the skills definitive of the sport. If these are correct, it would follow that all sports are contests and that a range of sporting activities, including nature sports, are not in fact sports at all. This paper first confronts the notion that sport and games must seek to resolve skill superiority through (...) consideration of sport activities that have no such aim. The reduction of sport to game is also shown to be untenable and due to misunderstanding the point of sport activities, specifically, why people engage in them. This leads to reconsideration of the dominance of an instrumental conception of sport and the pursuit of excellence as anthropomaximising efficiency. The Norwegian tradition of frilutsliv is explored as a counterpoint to both conventional and nature sport. (shrink)

This paper is an examination of the concept of recognition and its connection with identity and respect. This is related to the question of how women are or are not adequately recognised or respected for their achievements in sport and whether eliminating sex segregation in sport is a solution. This will require an analysis of the concept of excellence in sport, as well as the relationship between fairness and inclusion in an activity that is fundamentally about bodily movement. I argue (...) that attempts to address the problem of women’s recognition in sport need to do so in ways that neither eliminate sport as a fairness regulated system for developing individual excellence in bodily movement nor that prevent women’s achievement of sporting excellence, with the regard that belongs to them. Doing this requires us to decide whether sport is about champions or about individual excellence. (shrink)

Excellence in sport performance is normally taken to be a matter of superior performance of physical movements or quantitative outcomes of movements. This paper considers whether a wider conception can be afforded by certain kinds of nature based sport. The interplay between technical skill and aesthetic experience in nature based sports is explored, and the extent to which it contributes to a distinction between different sport-based approaches to natural environments. The potential for aesthetic appreciation of environmental engagement is found to (...) be strongly dependent on whether or not environmental engagement is exploited for the end of producing a quantifiable result or enhancing technical skill. It is also argued that an existential rather than spectatorial attitude to aesthetic experience is offered by specifically nature oriented sport. Aesthetic experience achieved in this way is therefore neither passive nor detached, but extends Berleant's concept of participatory environmental aesthetics and underpins both an alternate (wide) conception of excellence in sport activity and a richer experience of aesthetic engagement than more objectivised standpoints.

This paper responds to Kevin Krein’s claim in that the particular value of nature sports over traditional ones is that they offer intensity of sport experience in dynamic interaction between an athlete and natural features. He denies that this intensity is derived from competitive conflict of individuals and denies that nature sport derives its value from internal conflict within the athlete who carries out the activity. This paper responds directly to Krein by analysing ‘intensity’ in sport in terms of the (...) relationship between attention and reflection and the interaction between self and environment. I reply directly to Krein’s rejection of self-competition as based on a mischaracterisation of internal struggle and argue that the weighing of incompatible desires does not involve a fragmented self. I argue that the unique intensity to which Krein refers is strongly comparable to the Kantian conception of the sublime and explore how sublime experience fits Krein’s account and outline some serious problems that such an ideal of experience poses for nature sport. (shrink)

In a recent paper, Kevin Krein argues that the notion of self-competition is misplaced in adventure sports and of only limited application altogether, for two main reasons: (i) the need for a consistent and repeatable measure of performance; and (ii) the requirement of multiple competitors. Moreover, where an individual is engaged in a sport in which the primary feature with which they are engaged is a natural one, Krein argues that the more accurate description of their activity is not 'competition', (...) but an attempt at harmonious interaction. I raise a number of problems against both criteria and argue that traditional and adventure sports do both involve self-competition on at least two levels: bettering one's previous performance and resisting the desire to quit. I argue that self-reflexive competition is not so much with one's self (which is philosophically absurd), but within one's self, between conflicting motivations and desires. I explore what is involved in self-reflexive competition, particularly at a phenomenological, self-constituting level, and raise the question of whether it is appropriate for activity in wilder natural environments.

Previous discussions on the value of sport in remote locations have concentrated on 1) environmental and process concerns, with the rejection of competition and goal-directed or use oriented activity, or 2) the value of risk and dangerous sport for self-affirmation. It is argued that the value of risk in remote sport is in self-knowledge rather than self-affirmation and that risk in remote sport, while enhancing certain kinds of experience, is not necessary. The value of remote sport is in offering the (...) opportunity for experience that enhances the participants’ knowledge both of self and of the environment with which they interact. (shrink)

Math prospective teachers must be able to think creatively and solve problems. The study looked into preservice teachers’ creative thinking and problem-solving abilities in statistics. The investigation was guided by a correlational design in a public university in the Philippines. Stratified random sampling was used to select the 103 study participants from two teacher education programs. Through google forms, data were collected using Torrance et al. (2008)’s tests of creative thinking and researcher-made statistics problem test. The findings revealed that preservice (...) teachers have commendable creative thinking, particularly fluency, flexibility, and elaboration skills. Still, they lack problem-solving skills in statistics, specifically with central tendency, dispersion, and position measures. The correlational analysis revealed no link between creative thinking and problem-solving. Still, creative thinking and problem-solving courses are recommended to help preservice teachers develop their fundamental skills as mathematics educators. (shrink)

This paper considers the importance of play as a conventional space for hypothetical self-expression and self-trial, its importance for determination of identity, and for development of self-possibilities. Expanding such possibilities in play enables challenging of socially entrenched assumptions concerning possible and appropriate identities. Discussion is extended to the contexts of gender performance (drag) and sport-play. It is argued that play proceeds on the basis of a fundamental pretence of reality that must be taken seriously by its participants; this discussion includes (...) considerations of serious and ironical play, “playing-at”, and travesty.

This paper explores ludonarrative dissonance as it occurs in sport, primarily as the conflict experienced by participants between dominant narratives and self-generated interpretations of embodied experience. Taking self-narrative as a social rather than isolated production, the interaction with three basic categories of dominant narrative is explored: transformative, representing a spectrum from revelatory to distorting, bullying and colonising. These forms of dominant narrative prescribe interpretations of the player’s experience of play and of self that displace their own, with the end result (...) of dissonance and self-alienation.

Kierkegaard shows two contrary attitudes to woman and the feminine: misogyny and celebration. The Kierkegaardian structure of selfhood, because combined with a hierarchical assumption about the relative value of certain human characteristics, and their identification as male or female, argues that woman is a lesser self. Consequently, the claim that the Kierkegaardian ideal of selfhood is androgynist is rejected, though it is the latter assumptions alone that force this conclusion.

This paper refines a number of theoretical distinctions relevant to deceptive play, in particular the difference between merely misleading actions and types of simulation commonly considered beyond the pale, such as diving. To do so, I rely on work in the philosophy of language about conversational convention and implicature, the distinction between lying and misleading, and their relation to concepts of seduction and bullshit. The paper works through a number of possible solutions to the question of what is wrong with (...) simulation and its difference from strategic fouling, including the argument that games and their rules operate like contracts. I conclude that the wrongness lies in the injustice of unfair advantage gained through actions that silence opposition by resort to unanswerable play. (shrink)

This paper argues against the conception of sport as theatre. Theatre and sport share the characteristic that play is set in a conventionally-defined hypothetical reality, but they differ fundamentally in the relative importance of audience and the narrative point of view. Both present potential for participants for development of selfhood through play and its personal possibilities. But sport is not essentially tied to audience as is theatre. Moreover, conceptualising sport as a form of theatre valorises the spectator’s narrative as normative (...) for sport experience over that of the participant athlete or player, eliding player experience. Imposition of external narratives over experience risks fossilising interpretation and inhibits the beneficial effects of play for self-realisation, especially as a form of self-examination and creation through internal self-narrative. (shrink)

I argue that understanding the self in terms of narrative construction does not preclude the possibility of error concerning one’s own self. Identity is a projection of first and second-order desires and a product of choice in relation to desire. Self-deceit appears in this connection as a response to an identity that one has constructed through choice and/or desire but not acknowledged in one’s self-account, reflecting a conflict between desires or a motivated failure to account. This analysis is applied primarily (...) to acknowledgement of one’s sexual identity. (shrink)

The concept of acting intentionally is an important nexus where ‘theory of mind’ and moral judgment meet. Preschool children’s judgments of intentional action show a valence-driven asymmetry. Children say that a foreseen but disavowed side-effect is brought about 'on purpose' when the side-effect itself is morally bad but not when it is morally good. This is the first demonstration in preschoolers that moral judgment influences judgments of ‘on-purpose’ (as opposed to purpose influencing moral judgment). Judgments of intentional action are usually (...) assumed to be purely factual. That these judgments are sometimes partly normative — even in preschoolers — challenges current understanding. Young children’s judgments regarding foreseen side-effects depend upon whether the children process the idea that the character does not care about the side-effect. As soon as preschoolers effectively process the ‘theory of mind’ concept, NOT CARE THAT P, children show the side-effect effect.idea.. (shrink)

Ambiguity in the athlete’s perception and description of pain that opens the door to a series of reinterpretations of athletic experience and events that argue the development of an increasingly inauthentic relation to self and others on the part of those who consume performance as third parties (spectators) and ultimately those who produce it first hand (athletes). The insertion of the spectator into the sport situation as a consumer of the athlete’s activity and the preference given to spectator interpretation shift (...) control of meaning away from the athlete and encourage a demand for athlete suffering in aid of the spectator’s own need for meaning. Through discussions of the function of narrative in sport spectacle, the witnessing role of spectators, and the phenomenon of vicarious substitution, I discuss the representation of the athlete as a character ideal and moral exemplar. At a more developed level of external interpretation, the athlete (or team) becomes the champion of the spectator, the role model or focal point of civic pride whose victory asserts the ascendence of my team and town over yours; and finally, the athlete or team is the intentional object of fan identification: my team is me. I conclude that the existential commitment of the spectator as devoted fan is an inauthentic one. (shrink)

I respond to a hypothetical critique of sport, drawing on primarily post-modernist sources, that would view the high performance athlete in particular as a product of the application of technical disciplines of power and that opposes sport and play as fundamentally antithetical. Through extensive discussion of possible definitions of play, and of performance, I argue that although much of the critique is valid it confuses a method of sport for the whole of it. Play is indeed a noncompellable spontaneity, but (...) one that involves the improvisational transformation of the technical skills of a sport within the context of a dynamic situation. Technique is a condition of heightened play; it does not produce it. This also means that the best play is not undisciplined. Play and sport can exist apart, but both are better combined. (shrink)

This tutorial is for beginners wanting to learn the basics of propositional logic; the simplest of the formal systems of logic. Leslie Allan introduces students to the nature of arguments, validity, formal proofs, logical operators and rules of inference. With many examples, Allan shows how these concepts are employed through the application of three different methods for proving the formal validity of arguments.

Leslie Allan demonstrates how human rights are unproblematic for utilitarian moral theory and how, upon consideration, utilitarianism turns out to be the best theory for justifying human rights. Using case studies of historical and contemporary human rights conventions and recent psychological research, he argues how our concept of human rights is founded on the satisfaction of fundamental human needs and the consequences for human happiness.

This paper explores the role of generics in social cognition. First, we explore the nature and effects of the most common form of generics about social kinds. Second, we discuss the nature and effects of a less common but equally important form of generics about social kinds. Finally, we consider the implications of this discussion for how we ought to use language about the social world.

Human social intelligence comprises a wide range of complex cognitive and affective processes that appear to be selectively impaired in autistic spectrum disorders. The study of these neuro- developmental disorders and the study of canonical social intelligence have advanced rapidly over the last twenty years by investigating the two together. Specifically, studies of autism have provided important insights into the nature of ‘theory of mind’ abilities, their normal development and underlying neural systems. At the same time, the idea of impaired (...) development of the neurocognitive mechanisms underlying ‘theory of mind’ has shed new light on the nature of autistic disorders. This general approach is not restricted to the study of impairments but extends to mapping areas of social intelligence that are spared in autism. Here we investigate basic moral judgment and find that it appears to be substantially intact in children with autism who are severely impaired in ‘theory of mind’. At the same time, we extend studies of moral reasoning in normal development by way of a new control task, the ‘cry baby’ task. Cry baby scenarios, in which the distress of the victim is ‘unreasonable’ or ‘unjustified,’ do not elicit moral condemnation from normally developing preschoolers or from children with autism. Judgments of moral transgressions in which the victim displays distress are therefore not likely the result of a simple automatic reaction to the distress and more likely involve moral reasoning. Mapping the cognitive co-morbidity patterns of disordered development should encompass both impairments and sparings because both will be needed to make sense of the neural and genetic levels.

Subjectivists claim that the absence of a theological or metaphysical grounding to moral judgements renders them all as simply statements about our subjective wants and preferences. Leslie Allan argues that the subjectivists' case rests on a misunderstanding of the nature of moral objectivity. He presents the view that subjectivists mistakenly counterpoise the ideal of moral objectivity with the expression of individual preferences. Being objective in moral deliberation, Allan argues, should be regarded instead as the antithesis of parochial and biased (...) reasoning. This account of moral objectivity, he concludes, makes sense of a long-standing universalist tradition in moral philosophy. (shrink)

The existence of evil, pain and suffering is considered by many philosophers to be the most vexed question concerning the existence of an omnipotent, omniscient and morally perfect deity. Why would a loving God permit wanton acts of cruelty and misery on the scale witnessed throughout human history? In this essay, Leslie Allan evaluates four common theistic responses to this problem, highlighting the benefits and challenges faced by each approach. He concludes with a critical examination of a theistic defence (...) designed to show that the problem of evil is not a problem at all. (shrink)

In this article I provide an overview of the moral and medical questions surrounding the use of cognitive enhancers. This discussion will be framed in light of 4 key considerations: (1) is there a difference between therapy and enhancement? (2) How safe are these interventions? (3) Is the use of nootropics cheating? (4) Would enhancers create a further divide of social inequality where only the very wealthy have access to them?

In this article, network science is discussed from a methodological perspective, and two central theses are defended. The first is that network science exploits the very properties that make a system complex. Rather than using idealization techniques to strip those properties away, as is standard practice in other areas of science, network science brings them to the fore, and uses them to furnish new forms of explanation. The second thesis is that network representations are particularly helpful in explaining the properties (...) of non-decomposable systems. Where part-whole decomposition is not possible, network science provides a much-needed alternative method of compressing information about the behavior of complex systems, and does so without succumbing to problems associated with combinatorial explosion. The article concludes with a comparison between the uses of network representation analyzed in the main discussion, and an entirely distinct use of network representation that has recently been discussed in connection with mechanistic modeling.

Metaphysical dualities divorce humankind from its natural environment, dualities that can precipitate environmental disaster. Loyal Rue in Religion Is Not About God seeks to resolve the abstract modalities of religion and naturalism in a unified monistic ecocentric metaphysic characterized as religious naturalism.

Only (...) then will humanity be equipped to address the environmental imperative. (shrink)

Conspiracy theories should be neither believed nor investigated - that is the conventional wisdom. I argue that it is sometimes permissible both to investigate and to believe. Hence this is a dispute in the ethics of belief. I defend epistemic ‘oughts’ that apply in the first instance to belief-forming strategies that are partly under our control. I argue that the policy of systematically doubting or disbelieving conspiracy theories would be both a political disaster and the epistemic equivalent of self-mutilation, since (...) it leads to the conclusion that history is bunk and the nightly news unbelievable. In fact (of course) the policy is not employed systematically but is only wheeled on to do down theories that the speaker happens to dislike. I develop a deductive argument from hard-to-deny premises that if you are not a ‘conspiracy theorist’ in my anodyne sense of the word then you are an ‘idiot’ in the Greek sense of the word, that is, someone so politically purblind as to have no opinions about either history or public affairs. The conventional wisdom can only be saved (if at all) if ‘conspiracy theory’ is given a slanted definition. I discuss some slanted definitions apparently presupposed by proponents of the conventional wisdom (including, amongst others, Tony Blair) and conclude that even with these definitions the conventional wisdom comes out as deeply unwise. I finish up with a little harmless fun at the expense of David Aaronvitch whose abilities as a rhetorician and a popular historian are not perhaps matched by a corresponding capacity for logical thought.

In this address, Leslie Allan shares his early experiences and how they shape his humanist outlook today. He then outlines what he considers to be the three core principles underlying the humanist world view and illustrates their application with historical and contemporary examples. He concludes by drawing upon each of these principles to tease out what it means to live a good life; a life of meaning and purpose.

Hume describes his own “open, social, and cheerful humour” as “a turn of mind which it is more happy to possess, than to be born to an estate of ten thousand a year.” Why does he value a cheerful character so highly? I argue that, for Hume, cheerfulness has two aspects—one manifests as mirth in social situations, and the other as steadfastness against life’s misfortunes. This second aspect is of special interest to Hume in that it safeguards the other virtues. (...) And its connection with the first aspect helps explain how it differs from Stoic tranquility. For Hume, I argue, philosophy has a modest role in promoting human happiness by preserving cheerfulness. (shrink)

We argue that generic generalizations about racial groups are pernicious in what they communicate (both to members of that racial group and to members of other racial groups), and may be central to the construction of social categories like racial groups. We then consider how we should change and challenge uses of generic generalizations about racial groups.

There has been much debate regarding the 'double-effect' of sedatives and analgesics administered at the end-of-life, and the possibility that health professionals using these drugs are performing 'slow euthanasia.' On the one hand analgesics and sedatives can do much to relieve suffering in the terminally ill. On the other hand, they can hasten death. According to a standard view, the administration of analgesics and sedatives amounts to euthanasia when the drugs are given with an intention to hasten death. In this (...) paper we report a small qualitative study based on interviews with 8 Australian general physicians regarding their understanding of intention in the context of questions about voluntary euthanasia, assisted suicide and particularly the use of analgesic and sedative infusions (including the possibility of voluntary or non-voluntary 'slow euthanasia'). We found a striking ambiguity and uncertainty regarding intentions amongst doctors interviewed. Some were explicit in describing a 'grey' area between palliation and euthanasia, or a continuum between the two. Not one of the respondents was consistent in distinguishing between a foreseen death and an intended death. A major theme was that 'slow euthanasia' may be more psychologically acceptable to doctors than active voluntary euthanasia by bolus injection, partly because the former would usually only result in a small loss of 'time' for patients already very close to death, but also because of the desirable ambiguities surrounding causation and intention when an infusion of analgesics and sedatives is used. The empirical and philosophical implications of these findings are discussed. (shrink)

Narratologists commonly draw a distinction between the story and those things that tell the story- the tellings, as I will call them here. Here is an example intended to highlight that distinction. The Parable of the Sower is a parable found in the New Testament books of Matthew, Mark and Luke, and in the non-canonical Gospel of Thomas. Though the relevant pieces of text in the Gospels are remarkably similar, no two of the four are identical. The verses in Matthew, (...) Mark and Luke, have been translated and paraphrased, along with the rest of the Bible, into literally thousands of different languages and versions, all of which include the The Parable of the Sower.

Nihilism, Nietzsche and the Doppelganger Problem Was Nietzsche a nihilist? Yes, because, like J. L. Mackie, he was an error-theorist about morality, including the elitist morality to which he himself subscribed. But he was variously a diagnostician, an opponent and a survivor of certain other kinds of nihilism. Schacht argues that Nietzsche cannot have been an error theorist, since meta-ethical nihilism is inconsistent with the moral commitment that Nietzsche displayed. Schacht’s exegetical argument parallels the substantive argument (advocated in recent years (...) by Wright and Blackburn) that Mackie’s error theory can’t be true because if it were, we would have to give up morality or give up moralizing. I answer this argument with a little bit of help from Nietzsche. I then pose a problem, the Doppelganger Problem, for the meta-ethical nihilism that I attribute to Mackie and Nietzsche. (If A is a moral proposition then not-A is a moral proposition: hence not all moral propositions can be false.) I solve the problem by reformulating the error theory and also deal with a variant of the problem, the Reinforced Doppelganger, glancing at a famous paper of Ronald Dworkin’s. Thus, whatever its demerits, the error theory, is not self-refuting, nor does it require us to give up morality. (shrink)

Hayek’s philosophical psychology as set out in his The Sensory Order (1952) has, for the most part, been neglected. Despite being lauded by computer scientist grandee Frank Rosenblatt and by Nobel prize-winning biologist Gerald Edelman, cognitive scientists -- with a few exceptions -- have yet to discover Hayek’s philosophical psychology. On the other hand, social theorists, Hayek’s traditional disciplinary constituency, have only recently begun to take note and examine the importance of psychology in the complete Hayek corpus. This volume brings (...) together for the first time state-of-the-art contributions from neuroscientists and philosophers of mind as well as economists and social theorists, all critically engaging in many aspects of Hayek’s philosophical psychology.

The author contends that classifying theories in the field of meta-ethics along a single dimension misses important nuances in each theory. With the increased sophistication and complexity of meta-ethical analyses in the modern era, the traditional cognitivist–non-cognitivist and realist–anti-realist categories no longer function adequately. The author categorizes the various meta-ethical theories along three dimensions. These dimensions focus on the linguistic analysis offered by each theory, its metaphysical commitments and its degree of normative tolerance.

A longstanding issue in attempts to understand the Everett (Many-Worlds) approach to quantum mechanics is the origin of the Born rule: why is the probability given by the square of the amplitude? Following Vaidman, we note that observers are in a position of self-locating uncertainty during the period between the branches of the wave function splitting via decoherence and the observer registering the outcome of the measurement. In this period it is tempting to regard each branch as equiprobable, but we (...) argue that the temptation should be resisted. Applying lessons from this analysis, we demonstrate (using methods similar to those of Zurek's envariance-based derivation) that the Born rule is the uniquely rational way of apportioning credence in Everettian quantum mechanics. In doing so, we rely on a single key principle: changes purely to the environment do not affect the probabilities one ought to assign to measurement outcomes in a local subsystem. We arrive at a method for assigning probabilities in cases that involve both classical and quantum self-locating uncertainty. This method provides unique answers to quantum Sleeping Beauty problems, as well as a well-defined procedure for calculating probabilities in quantum cosmological multiverses with multiple similar observers.

The author mounts a case against the libertarian and hard determinist's thesis that free will is impossible in a deterministic world. He charges incompatibilists with misconstruing ordinary 'free will' talk by overlaying common language with their own metaphysical presuppositions. Through a review of ordinary discourse and recent developments in jurisprudence and the sciences, he draws together the four key factors required for an act to be free. He then puts his 4C theory to work in giving a credible account of (...) how caused human agents 'could have done otherwise'. (shrink)

Conpiracy theories are widely deemed to be superstitious. Yet history appears to be littered with conspiracies successful and otherwise. (For this reason, "cock-up" theories cannot in general replace conspiracy theories, since in many cases the cock-ups are simply failed conspiracies.) Why then is it silly to suppose that historical events are sometimes due to conspiracy? The only argument available to this author is drawn from the work of the late Sir Karl Popper, who criticizes what he calls "the conspiracy theory (...) of society" in The Open Society and elsewhere. His critique of the conspiracy theory is indeed sound, but it is a theory no sane person maintains. Moreover, its falsehood is compatible with the prevalence of conspiracies. Nor do his arguments create any presumption against conspiracy theories of this or that. Thus the belief that it is superstitious to posit conspiracies is itself a superstition. The article concludes with some speculations as to why this superstition is so widely believed. (shrink)
