Humour is worthy of serious ethical consideration. However, it is often taken far too seriously. In this paper, it is argued that while humour is sometimes unethical, it is wrong much less often than many people think. Non-contextual criticisms, which claim that certain kinds of humour are always wrong, are rejected. Contextual criticisms, which take issue with particular instances of humour rather than types of humour, are more promising. However, it is common to overstate the number of contexts in which (...) humour is wrong. Various mistakes of this kind are highlighted and cautioned against. (shrink)

When the benefits of surgery do not outweigh the harms or where they do not clearly do so, surgical interventions become morally contested. Cutting to the Core examines a number of such surgeries, including infant male circumcision and cutting the genitals of female children, the separation of conjoined twins, surgical sex assignment of intersex children and the surgical re-assignment of transsexuals, limb and face transplantation, cosmetic surgery, and placebo surgery.

Neste trabalho, investigo a possibilidade de compatibilidade entre o pessimismo filosófico e a compreensão da morte como um mal para quem morre. Por pessimismo filosófico, compreendo a doutrina filosófica que mantém como tese fundamental que a não-existência é preferível à existência, de modo que o pessimismo é tomado como a filosofia de que a vida não vale a pena ser vivida. Por mal da morte, me refiro à compreensão da morte como um dano para o indivíduo que morre, cujo pressuposto (...) em diferentes abordagens contemporâneas é o de que a morte só é um mal no caso de continuar existindo ser preferível a deixar de existir. Desse modo, o problema discutido é a aparente incompatibilidade entre a tese de que a não-existência é preferível à existência e a tese de que continuar existindo é preferível a deixar de existir. Busco demonstrar que essa (in)compatibilidade depende do modo como fundamentamos o pessimismo filosófico. Para tanto, examino dois argumentos para o pessimismo filosófico e suas implicações para o mal da morte: o argumento a priori de Arthur Schopenhauer e o argumento da assimetria de David Benatar. Concluo que o primeiro desses argumentos nos leva para a conclusão de que a morte não é um mal, mas que o segundo argumento compatibiliza o pessimismo filosófico e a compreensão da morte como um mal para quem morre.

Contemporary philosopher David Benatar has advanced the self-evidently controversial claim that “coming into existence is always a harm.” Benatar’s argument turns on the basic asymmetry between pleasure and pain, an asymmetry he seeks to explain by the principle that those who never exist cannot be deprived. Benatar’s import is almost incredible: humans should cease to procreate immediately, thereby engendering the extinction of the species—a view known as “anti-natalism.” According to many of his readers, the ancient Hebrew (...) sage Qoheleth expresses a pessimistic nihilism that runs as thick as Benatar’s. Prima facie grounding for this assertion is that Qoheleth, like Benatar, raises the issue of whether coming into existence may be a harm—and gives an affirmative answer. In two passages, Ecclesiastes 6:1-6 and 4:1-3, Qoheleth declares that an unborn hypothetical person is “better off” than their existent counterpart. Yet the meaning and implication of these words is far from obvious. Does Qoheleth imply that the non-exister’s state, and non-existence in general, is universally superior to existence? Or is he instead speaking exceptionally, of particular persons in rare circumstances? By examining the two “better”-statements in their literary context, I will argue that Qoheleth intends these examples as exceptions. He does not go so far as to make the supremely nihilistic claim that coming into existence is always, or even generally, a net harm; yet, he does concede that in certain cases, it can be. Beyond this, I will explore how the two thinkers’ divergent conclusions can be traced to a deeper difference of philosophical method. This question concerning non-existence opens a window to Qoheleth’s broader scheme of values and therefore serves as a surprisingly useful entry point by which to engage his philosophy. The paper utilizes the methodology Jaco Gericke has recently termed “philosophical criticism,” but specifically applied to Qoheleth. (shrink)

In his book, The Human Predicament, David Benatar claims that our individual lives and human life, in general, do not make a difference beyond Earth and, therefore, are meaningless from the vast, cosmic perspective. In this paper, I will explain how what we do matters from the cosmic perspective. I will provide examples of how human beings have transcended our limits, thereby giving human life some meaning from the cosmic perspective. Also, I will argue that human life could (...) become even more meaningful by making some fundamental achievements, such as determining how life originated. (shrink)

David Benatar claims that everyone was seriously harmed by coming into existence. To spare future persons from this suffering, we should cease having children, Benatar argues, with the result that humanity would gradually go extinct. Benatar’s claim of universal serious harm is baseless. Each year, an estimated 94% of children born throughout the world do not have a serious birth defect. Furthermore, studies show that most people do not experience chronic pain. Although nearly everyone experiences acute (...) pain and discomforts, such as thirst, these experiences have instrumental value. For example, when a person picks up a hot object, in response to the pain, the person releases the object, thereby preventing serious harm. The standard that Benatar uses to evaluate the quality of our lives is arbitrary, as I will demonstrate. His proposal that we phase humanity out of existence by ceasing to have children is misguided and an overreaction to the problem of human suffering. The ‘threshold conception of harm’, which is a targeted approach for preventing future persons from suffering, is a more sensible approach. (shrink)

This paper presents a critique of David Benatar’s arguments on the badness of all human lives. I argue that even if Benatar is right that there is an asymmetry between the good and the bad in life so that each “unit” of bad is indeed more effective than each “unit” of good, lives in which there is a lot of good and only little bad are still overall good. Even if there are more unfulfilled than fulfilled desires (...) in life, a distinction should be drawn between desires to fulfill important goals and desires to fulfill trivial ones, and Benatar’s claim is untrue of the former. Benatar’s claim that we cannot really know that the quality of our own lives is good is problematic, but even if it were true, it would not show that we cannot estimate correctly the quality of other people’s lives, which is the point at issue.

A critical overview of the latest discussion of anti-natalism, with particular reference to David Benatar's work and three additional rationales for anti-natalism that differ from Benatar's.

David Benatar argues that coming into existence is always a harm, and that – for all of us unfortunate enough to have come into existence – it would be better had we never come to be. We contend that if one accepts Benatar’s arguments for the asymmetry between the presence and absence of pleasure and pain, and the poor quality of life, one must also accept that suicide is preferable to continued existence, and that his view therefore (...) implies both anti-natalism and pro-mortalism . This conclusion has been argued for before by Elizabeth Harman – she takes it that because Benatar claims that our lives are ‘awful’, it follows that ‘we would be better off to kill ourselves’ (Harman 2009: 784). Though we agree with Harman’s conclusion, we think that her argument is too quick, and that Benatar’s arguments for non-pro-mortalism deserve more serious consideration than she gives them. We make our case using a tripartite structure. We start by examining the prima facie case for the claim that pro-mortalism follows from Benatar’s position, presenting his response to the contrary, and furthering the dialectic by showing that Benatar’s position is not just that coming into existence is a harm, but that existence itself is a harm. We then look to Benatar’s treatment of the Epicurean line, which is important for him as it undermines his anti-death argument for non-pro-mortalism. We demonstrate that he fails to address the concern that the Epicurean line raises, and that he cannot therefore use the harm of death as an argument for non-pro-mortalism. Finally, we turn to Benatar’s pro-life argument for non-pro-mortalism, built upon his notion of interests, and argue that while the interest in continued existence may indeed have moral relevance, it is almost always irrational. Given that neither Benatar’s anti-death nor pro-life arguments for non-pro-mortalism work, we conclude that pro-mortalism follows from his anti-natalism, As such, if it is better never to have been, then it is better no longer to be. -/- .

David Benatar has argued both for anti-natalism and for a certain pessimism about life's meaning. In this paper, I propose that these positions are expressions of a deeply impersonal philosophical temperament. This is not a problem on its own; we all have our philosophical instincts. The problem is that this particular temperament, I argue, leads Benatar astray, since it prevents him from answering a question that any moral philosopher must answer. This is the question of rational authority, (...) which requires the moral philosopher to say why existing human agents have strong practical reasons to comply with the philosopher's dictates. A purely impersonal ethical system can never do this, and this is why Benatar has no answer to this question. (shrink)

In The Human Predicament, David Benatar develops and defends the annihilation view, according to which “death is bad in large part because it annihilates the being who dies.” In this paper, I make both a positive and negative argument against the annihilation view. My positive argument consists in showing that the annihilation view generates implausible consequences in cases where one can incur some other (intrinsic) bad to avoid the supposed (intrinsic) bad of annihilation. More precisely, Benatar’s view (...) entails that would be prudent for someone to incur a non-trivial amount of pain in order to avoid being annihilated, even in cases in which the additional life one would live would not be good at all for the person living it. Yet, it seems imprudent to incur any amount of pain to continue living a life that isn’t good for the person living it, so annihilation itself cannot be (intrinsically) bad. Avoiding the implausible consequences I identify requires denying that annihilation is itself bad. My negative argument consists in demonstrating that standard forms of deprivationism can avoid all three of the major problems that Benatar attributes to them without having to posit that annihilation itself is bad.

This article examines one of the sources of David Benatar’s anti-natalism. This is the view that ‘all procreation is [morally] wrong.’ (Benatar and Wasserman, 2015:12) One of its sources is the claim that each of our lives is objectively bad, hence bad whether we think so or not. The question I will pose is whether the constraints of metaphysical naturalism allow for an objective devaluation of human life sufficiently negative to justify anti-natalism. My thesis is that metaphysical (...) naturalism does not have the resources to support such a negative evaluation. Metaphysical naturalism is the view that causal reality is exhausted by nature, the space-time system and its contents. The gist of my argument is that the ideal standards relative to which our lives are supposed to be axiologically substandard cannot be merely subjective expressions of our desires and aversions; they must be (i) objectively binding standards that are (ii) objectively possible in the sense of concretely realizable. The realizability condition, however, cannot be satisfied on metaphysical naturalism; ergo, failure to meet these ideal standards cannot show that our lives are objectively bad. (shrink)

The concept of antinatalism is now becoming popular on the Internet. Many online newspaper articles deal with this topic, and numerous academic papers on antinatalism have been published over the past ten years in the fields of philosophy and ethics. The word “antinatalism” was first used in the current meaning in 2006, when the two books that justify the universal negation of procreation were published: one by David Benatar and the other by Théophile de Giraud. However, we can (...) find various prototypes of antinatalistic thoughts in ancient Greece, ancient India, and modern Europe. You might recall the name Schopenhauer. In this paper, I briefly summarize the history of antinatalistic thoughts and propose a set of categories on antinatalism and related thoughts. (shrink)

In his book Better Never to Have Been, David Benatar argues that it is generally all things considered wrong to procreate, such that if everyone acted in a morally ideal way, humanity would elect to extinguish the species. I aim to carefully question the premises and inferences that lead Benatar to draw this anti-natalist conclusion, indicating several places where one could sensibly elect to disembark from the train of argument heading toward such a radical view.

This paper uses a dilemma presented by David Benatar to explore the challenges that ‘Sexual Liberals’ face in giving a satisfactory account of sexual ethics. A satisfactory Sexual Liberal account of sexual ethics must be able to fully explain the wrongness of sexual assault without implying that sexual activity should be restricted to those in love. The assumption that this is impossible may be due to mistakes in our thinking about sexual assault. However, even when such mistakes are (...) resolved, producing a satisfactory account of sexual ethics requires Sexual Liberals to confront the significance of the sexual in human life. I describe an account of sexual desire that explains the significance of the sexual in human life without forcing us to endorse a restrictive sexual ethics. (shrink)

There can be no doubt that discrimination based on sex, race, ethnicity, religion or beliefs should not be tolerated in academia. Surprisingly, however, in recent years, policies of Diversity, Inclusion and Equity(DIE), officially introduced to counteract discrimination, have increasingly led to quite the opposite result: the exclusion of individuals who do not share a radical 'woke' ideology on identity politics (feminism, other gender activisms, critical race theory, etc.), and to the suppression of the academic freedom to discuss such dogmas. This (...) subversion of academia ― disguised Trojan-horse style as universal human rights advocacy ― is unacceptable because academia must be politically neutral and protect freedom of speech, a cornerstone of professional scholarly activity without which universities as we know them will slowly but surely suffocate. -/- Our purpose here is to put together some particularly illustrative cases of such repression in a single book, testifying to a ubiquitous trend within western culture, irreducible to a few isolated complaints. The essays contained here illustrate the abuse of power, censorship and witch-hunts at many universities and research centres in the name of DIE. -/- List of coauthors in alphabetical order: Dorian Abbot, Tomonori Agoh, Gerhard Amendt, Ivar Arpi, David Benatar, Peter Boghossian, Civitas Research Team, David Díaz Pardo de Vera, Pedro Domingos, Janice Fiamengo, Étienne Forest, Jorge Gibert Galassi, Norman Goldstuck, José L.

The ethics of biological procreation has received a great deal of attention in recent years. Yet, as I show in this paper, much of what has come to be called procreative ethics is conducted in a strangely abstract, impersonal mode, one which stands little chance of speaking to the practical perspectives of any prospective parent. In short, the field appears to be flirting with a strange sort of practical irrelevance, wherein its verdicts are answers to questions that no-one is asking. (...) I go on to articulate a theory of what I call existential grounding, a notion which explains the role that prospective children play in the lives of many would-be parents. Procreative ethicists who want their work to have real practical relevance must, I claim, start to engage with this markedly first-personal kind of practical consideration. (shrink)

This paper presents and motivates a new philosophical and logical approach to truth and semantic paradox. It begins from an inferentialist, and particularly bilateralist, theory of meaning---one which takes meaning to be constituted by assertibility and deniability conditions---and shows how the usual multiple-conclusion sequent calculus for classical logic can be given an inferentialist motivation, leaving classical model theory as of only derivative importance. The paper then uses this theory of meaning to present and motivate a logical system---ST---that conservatively extends classical (...) logic with a fully transparent truth predicate. This system is shown to allow for classical reasoning over the full (truth-involving) vocabulary, but to be non-transitive. Some special cases where transitivity does hold are outlined. ST is also shown to give rise to a familiar sort of model for non-classical logics: Kripke fixed points on the Strong Kleene valuation scheme. Finally, to give a theory of paradoxical sentences, a distinction is drawn between two varieties of assertion and two varieties of denial. On one variety, paradoxical sentences cannot be either asserted or denied; on the other, they must be both asserted and denied. The target theory is compared favourably to more familiar related systems, and some objections are considered. (shrink)

The law views with suspicion statistical evidence, even evidence that is probabilistically on a par with direct, individual evidence that the law is in no way suspicious of. But it has proved remarkably hard to either justify this suspicion, or to debunk it. In this paper, we connect the discussion of statistical evidence to broader epistemological discussions of similar phenomena. We highlight Sensitivity – the requirement that a belief be counterfactually sensitive to the truth in a specific way – as (...) a way of epistemically explaining the legal suspicion towards statistical evidence. Still, we do not think of this as a satisfactory vindication of the reluctance to rely on statistical evidence. Knowledge – and Sensitivity, and indeed epistemology in general – are of little, if any, legal value. Instead, we tell an incentive-based story vindicating the suspicion towards statistical evidence. We conclude by showing that the epistemological story and the incentive-based story are closely and interestingly related, and by offering initial thoughts about the role of statistical evidence in morality.

This paper explores an initially attractive principle connecting beliefs in general with beliefs about what beliefs are rational. The principle turns out to be violated by intuitively rational beliefs in some situations. The paper lays out some options for reacting to this fact.

Recent methodological debates regarding the place of feasibility considerations in normative political theory are hindered for want of a rigorous model of the feasibility frontier. To address this shortfall, I present an analysis of feasibility that generalizes the economic concept of a production possibility frontier and then develop a rigorous model of the feasibility frontier using the familiar possible worlds technology. I then show that this model has significant methodological implications for political philosophy. On the Target View, a political ideal (...) presents a long-term goal for morally progressive reform efforts and, thus, serves as an important reference point for our specification of normative political principles. I use the model to show that we can- not reasonably expect that adopting political ideals as long-term reform objectives will guide us toward the realization of morally optimal feasible states of affairs. I conclude by proposing that political philosophers turn their attention to the analysis of actual social failures rather than political ideals. (shrink)

Political philosophers frequently claim that political ideals can provide normative guidance for unjust and otherwise nonideal circumstances. This is mistaken. This paper demonstrates that political ideals contribute nothing to our understanding of the normative principles we should satisfy amidst unjust or otherwise nonideal circumstances.

It is conventional wisdom among political philosophers that ideal principles of justice must guide our attempts to design institutions to avert actual injustice. Call this the ideal guidance approach. I argue that this view is misguided— ideal principles of justice are not appropriate "guiding principles" that actual institutions must aim to realize, even if only approximately. Fortunately, the conventional wisdom is also avoidable. In this paper, I develop an alternative approach to institutional design, which I call institutional failure analysis. The (...) basic intuition of this approach is that our moral assessment of institutional proposals is most effective when we proceed from a detailed understanding of the causal processes generating problematic social outcomes. Failure analysis takes the institutional primary design task to be obviating or averting institutional failures. Consequently, failure analysis enables theorists to prescribe more effective solutions to actual injustice because its focuses on understanding the injustice, rather than specifying an ideal of justice.

Recently, John Fischer has applied Frankfurt’s well-known counter-example to the principle of alternate possibilities to refute the traditional libertarian position which holds that a necessary condition for an agent’s decision (choice) to be free in the sense of freedom required for moral responsibility is that the decision not be causally determined, and that the agent could have avoided making it. Fischer’s argument has consequently led various philosophers to develop libertarian accounts of freedom which try to dispense with the avoidability constraint (...) on freedom. My purpose in this article is to show that Fischer’s attack on traditional libertarianism fails, and, therefore, it is premature to abandon that position. (shrink)

The purpose of this essay is to shed some light on a certain type of sentence, which I call a borderline contradiction. A borderline contradiction is a sentence of the form F a ∧ ¬F a, for some vague predicate F and some borderline case a of F , or a sentence equivalent to such a sentence. For example, if Jackie is a borderline case of ‘rich’, then ‘Jackie is rich and Jackie isn’t rich’ is a borderline contradiction. Many theories (...) of vague language have entailments about borderline contradictions; correctly describing the behavior of borderline contradictions is one of the many tasks facing anyone offering a theory of vague language. Here, I first briefly review claims made by various theorists about these borderline contradictions, attempting to draw out some predictions about the behavior of ordinary speakers. Second, I present an experiment intended to gather relevant data about the behavior of ordinary speakers. Finally, I discuss the experimental results in light of several different theories of vagueness, to see what explanations are available. My conclusions are necessarily tentative; I do not attempt to use the present experiment to demonstrate that any single theory is incontrovertibly true. Rather, I try to sketch the auxiliary hypotheses that would need to be conjoined to several extant theories of vague language to predict the present result, and offer some considerations regarding the plausibility of these various hypotheses. In the end, I conclude that two of the theories I consider are better-positioned to account for the observed data than are the others. But the field of logically-informed research on people’s actual responses to vague predicates is young; surely as more data come in we will learn a great deal more about which (if any) of these theories best accounts for the behavior of ordinary speakers.

Perceptualists say that having a pain in a body part consists in perceiving the part as instantiating some property. I argue that perceptualism makes better sense of the connections between pain location and the experiences undergone by people in pain than three alternative accounts that dispense with perception. Turning to fellow perceptualists, I also reject ways in which David Armstrong and Michael Tye understand and motivate perceptualism, and I propose an alternative interpretation, one that vitiates a pair of objections—due (...) to John Hyman—concerning the meaning of ‘Amy has a pain in her foot’ and the idea of bodily sensitivity. Perceptualism, I conclude, remains our best account of the location of pains. (shrink)

This paper discusses the significance of non-causal dependence for truthmaker theory. After introducing truthmaker theory (section 1), I discuss a challenge to it levelled by Benjamin Schnieder. I argue that Schnieder’s challenge can be met once we acknowledge the existence of non-causal dependence and of explanations which rely on it (sections 2 to 5). I then mount my own argument against truthmaker theory, based on the notion of non-causal dependence (sections 6 and 7).

This paper examines some of the methods animals and humans have of adapting their environment. Because there are limits on how many different tasks a creature can be designed to do well in, creatures with the capacity to redesign their environments have an adaptive advantage over those who can only passively adapt to existing environmental structures. To clarify environmental redesign I rely on the formal notion of a task environment as a directed graph where the nodes are states and the (...) links are actions. One natural form of redesign is to change the topology of this graph structure so as to increase the likelihood of task success or to reduce its expected cost, measured in physical terms. This may be done by eliminating initial states hence eliminating choice points; by changing the action repertoire; by changing the consequence function; and lastly, by adding choice points. Another major method for adapting the environment is to change its cognitive congeniality. Such changes leave the state space formally intact but reduce the number and cost of mental operations needed for task success; they reliably increase the speed, accuracy or robustness of performance. The last section of the paper describes several of these epistemic or complementary actions found in human performance. (shrink)

Certain situations seem to call for acknowledging the possibility that one’s own beliefs are biased or distorted. On the other hand, certain sorts of epistemic self-doubts (such as ‘I believe it’s raining, but it’s not’) seem paradoxical. And some have put forth epistemic principles requiring rational agents to regard their own credences as so-called ‘expert functions’. This paper examines the question of whether rationality requires agents to respect their own credences in a way in which they need not respect the (...) credences of others. (shrink)

I defend Joseph Melia’s nominalist account of mathematics from an objection raised by Mark Colyvan.

Hume introduced important innovations concerning the theory of ideas. The two most important are the distinction between impressions and ideas, and the use he made of the principles of association in explaining mental phenomena. Hume divided the perceptions of the mind into two classes. The members of one class, impressions, he held to have a greater degree of force and vivacity than the members of the other class, ideas. He also supposed that ideas are causally dependent copies of impressions. And, (...) unlike Locke and others, Hume makes positive use of the principle of association, both of the association of ideas, and, in a more limited way, of the association of impressions. Such associations are central to his explanations of causal reasoning, belief, the indirect passions (pride and humility, love and hatred), and sympathy. These views about impressions and ideas and the principles of association form the core of Hume’s science of human nature. Relying on them, he attempts a rigorously empirical investigation of human nature. The resulting system is a remarkable but complex achievement. (shrink)

To the extent that dualism is even taken to be a serious option in contemporary discussions of personal identity and the philosophy of mind, it is almost exclusively either Cartesian dualism or property dualism that is considered. The more traditional dualism defended by Aristotelians and Thomists, what I call hylemorphic dualism, has only received scattered attention. In this essay I set out the main lines of the hylemorphic dualist position, with particular reference to personal identity. First I argue that overemphasis (...) of the problem of consciousness has had an unhealthy effect on recent debate, claiming instead that we should emphasize the concept of form. Then I bring in the concept of identity by means of the notion of substantial form. I continue by analyzing the relation between form and matter, defending the traditional theses of prime matter and of the unicity of substantial form. I then argue for the immateriality of the substantial form of the human person, viz. the soul, from an account of the human intellect. From this follows the soul's essential independence of matter. Finally, although the soul is the immaterial bearer of personal identity, that identity is still the identity of an essentially embodied being. I explain how these ideas are to be reconciled. Footnotesa I am grateful to Stephen Braude, John Cottingham, John Haldane, David Jehle, Joel Katzav, Eduardo Ortiz, and Fred Sommers for helpful comments and discussion of a draft of this essay. I would also like to thank Ellen Paul, whose suggestions have helped greatly to improve the essay's style and content. (shrink)

An orthodox view in marketing ethics is that it is morally impermissible to market goods to specially vulnerable populations in ways that take advantage of their vulnerabilities. In his signature article “Marketing and the Vulnerable,” Brenkert (Bus Ethics Q Ruffin Ser 1:7–20, 1998) provided the first substantive defense of this position, one which has become a well-established view in marketing ethics. In what follows, we throw new light on marketing to the vulnerable by critically evaluating key components of Brenkert’s general (...) arguments. Specifically, we contend that Brenkert has failed to offer us any persuasive reasons to think that it is immoral to market to the vulnerable in ways that take advantage of their vulnerability. Although Brenkert does highlight the fact that the specially vulnerable are at greater risk of being harmed by already immoral marketing practices (e.g., deception, manipulation), he fails to establish that the specially vulnerable are a unique moral category of market clients or that there are special moral standards that apply to them. Moreover, even if Brenkert’s position were theoretically defensible, the practical implications of his position are far less tenable than he suggests. If our criticisms are sound, then Brenkert and others who endorse his position are seriously mistaken regarding how one can permissibly market products to vulnerable populations, and, in addition, they have improperly categorized certain morally permissible marketing practices as being immoral.

The 'completeness of physics' is the key premise in the causal argument for physicalism. Standard formulations of it fail to rule out emergent downwards causation. I argue that it must do this if it is tare in a valid causal argument for physicalism. Drawing on the notion of conferring causal power, I formulate a suitable principle, 'strong completeness'. I investigate the metaphysical implications of distinguishing this principle from emergent downwards causation, and I argue that categoricalist accounts of properties are better (...) equipped to sustain the distinction than dispositional essentialist accounts. Finally, I argue that the additional evidence needed for strong completeness renders the causal argument otiose for any properties amenable to scientific reduction. (shrink)

Suppose Alice asserts p, and the Caterpillar wants to disagree. If the Caterpillar accepts classical logic, he has an easy way to indicate this disagreement: he can simply assert ¬p. Sometimes, though, things are not so easy. For example, suppose the Cheshire Cat is a paracompletist who thinks that p ∨ ¬p fails (in familiar (if possibly misleading) language, the Cheshire Cat thinks p is a gap). Then he surely disagrees with Alice's assertion of p, but should himself be unwilling (...) to assert ¬p. So he cannot simply use the classical solution. Dually, suppose the Mad Hatter is a dialetheist who thinks that p ∧ ¬p holds (that is, he thinks p is a glut). Then he may assert ¬p, but it should not be taken to indicate that he disagrees with Alice; he doesn't. So he too can't use the classical solution. The Cheshire Cat and the Mad Hatter, then, have a common problem, and philosophers with opinions like theirs have adopted a common solution to this problem: appeal to denial. Denial, these philosophers suppose, is a speech act like assertion, but it is not to be understood as in any way reducing to assertion. Importantly, denial is something different from the assertion of a negation; this is what allows it to work even in cases where assertion of negation does not. Just as importantly, denial must express disagreement, since this is the job it's being enlisted to do. (shrink)

A satisfactory solution to the problem of consciousness would take the form of a simple yet fully general model that specifies the precise conditions under which any given state of consciousness occurs. Science has uncovered numerous correlations between consciousness and neural activity, but it has not yet come anywhere close to this. We are still looking for the Newtonian laws of consciousness. -/- One of the main difficulties with consciousness is that we lack a language in which to formulate illuminating (...) generalizations about it. Philosophers and scientists talk about "what it’s like", sensations, feelings, and perceptual states such as seeing and hearing. This language does not allow a precise articulation of the internal structures of conscious states and their inter-relations. It is inadequate to capture relations of the kind we are looking for between conscious states and physical states. -/- In this thesis I refine and defend a theory of consciousness which promises to solve this regimentation problem: the representational theory of consciousness. I argue that the representational theory can solve the regimentation problem and smooth out other important obstacles to a fruitful study of consciousness. I also make a case for the theory independently of its payoffs, and I discuss the leading opposing theories at some length. (shrink)

One of Leibniz’s more unusual philosophical projects is his presentation (in a series of unpublished drafts) of an argument for the conclusion that a time will necessarily come when “nothing would happen that had not happened before." Leibniz’s presentations of the argument for such a cyclical cosmology are all too brief, and his discussion of its implications is obscure. Moreover, the conclusion itself seems to be at odds with the main thrust of Leibniz’s own metaphysics. Despite this, we can discern (...) a serious and important point to Leibniz’s consideration of the doctrine, namely in what it suggests about the proper boundary between metaphysics and theology, on the one hand, and ordinary history (whether human or natural), on the other. And we can get a better sense of Leibniz purpose in the essays by considering them in the context of Leibniz's response to Thomas Burnet's "Telluris theoria sacra" (1681-89). Leibniz praises Burnet's history of earth for presenting a harmony between the principles of nature and grace, a harmony absent in the cosmogonies of Descartes and the Newtonians. But Leibniz also complains that Burnet misconceives the boundary between natural explanation and reflections on divine wisdom. And Leibniz's essays on cyclical cosmology suggest the alternative to Burnet's account: a natural history of the earth and its inhabitants should be radically autonomous from, even if ultimately harmonious with, theological principles.

This article addresses three main questions: What causes cognitive overload in the workplace? What analytical framework should be used to understand how agents interact with their work environments? How can environments be restructured to improve the cognitive workflow of agents? Four primary causes of overload are identified: too much tasking and interruption, and inadequate workplace infrastructure to help reduce the need for planning, monitoring, reminding, reclassifying information, etc… The first step in reducing the cognitive impact of these causes is to (...) enrich classical frameworks for understanding work environments, such as Newell and Simon’s notion of a task environment, by recognizing that our actual workplace is a superposition of many specific environments – activity spaces – which we slip between. Each has its own cost structure arising from the tools and resources available, including the cognitive strategies and interpretational frameworks of individual agents. These cognitive factors are significant, affecting how easy or difficult it is to perform an action, such as finding a specific paper in a “mess” desk. A few simple examples show how work environments can be redesigned and how restructuring can alter the cost structure of activity spaces. (shrink)

I discuss the prospects for novel communication methods in academic research. I describe communication tools which could enhance the practice of conceptual analysis.

Pogge and Wenar have recently argued that we are responsible for the persistence of the so-called ‘resource curse’. But their analyses are limited in important ways. I trace these limitations to their undue focus on the ways in which the international rules governing resource transactions undermine government accountability. To overcome the shortcomings of Pogge’s and Wenar’s analyses, I propose a normative framework organized around the social value of government responsiveness and discuss the implications of adopting this framework for future normative (...) assessment of the resource curse and our relationships to it.

In virtue of what are later and an earlier group members of one and the numerically same tradition? Gallie was one of the few philosophers to have engaged with issues surrounding this question.

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

Interview with Kai Nielsen conducted by David Rondel and Alex Sager.

We present data and argument to show that in Tetris—a real-time interactive video game—certain cognitive and perceptual problems are more quickly, easily, and reliably solved by performing actions in the world rather than by performing computational actions in the head alone. We have found that some translations and rotations are best understood as being used to implement a plan, or to implement a reaction. To substantiate our position we have implemented a computational laboratory that lets us record keystrokes and game (...) situations, as well as allows us to dynamically create situations. Using the data of over 30 subjects playing 6 games, tachistoscopic tests of some of these subjects, and results from our own successful efforts at building expert systems to play Tetris, we show why knowing how to use one’s environment to enhance speed and robustness are important components in skilled play.

Contemporary choreography offers a window onto creative processes that rely on harnessing the power of sensory sys- tems. Dancers use their body as a thing to think with and their sensory systems as engines to simulate ideas non- propositionally. We report here on an initial analysis of data collected in a lengthy ethnographic study of the making of a dance by a major choreographer and show how translating between different sensory modalities can help dancers and choreographer to be more creative.

A comparison of disjunctive theories of action and perception. The development of a theory of action that warrants the name, a disjunctive theory. On this theory, there is an exclusive disjunction: either an action or an event (in one sense). It follows that in that sense basic actions do not have events intrinsic to them.

Many people argue that history makes a special difference to the subjects of biology and psychology, and that history does not make this special difference to other parts of the world. This paper will show that historical properties make no more or less of a difference to biology or psychology than to chemistry, physics, or other sciences. Although historical properties indeed make a certain kind of difference to biology and psychology, this paper will show that historical properties make the same (...) kind of difference to geology, sociology, astronomy, and other sciences. Similarly, many people argue that nonhistorical properties make a special difference to the nonbiological and the nonpsychological world. This paper will show that nonhistorical properties make the same difference to all things in the world when it comes to their causal behavior and that historical properties make the same difference to all things in the world when it comes to their distributions. Although history is special, it is special in the same way to all parts of the world. (shrink)
