In evolutionary biology changes in population structure are explained by citing trait fitness distribution. I distinguish three interpretations of fitness explanations—the Two‐Factor Model, the Single‐Factor Model, and the Statistical Interpretation—and argue for the last of these. These interpretations differ in their degrees of causal commitment. The first two hold that trait fitness distribution causes population change. Trait fitness explanations, according to these interpretations, are causal explanations. The last maintains that trait fitness distribution correlates with population change but does not cause (...) it. My defense of the Statistical Interpretation relies on a distinctive feature of causation. Causes conform to the Sure Thing Principle. Trait fitness distributions, I argue, do not. *Received July 2009; revised October 2009. †To contact the author, please write to: Department of Philosophy/Institute for the History, Philosophy of Science and Technology, University of Toronto, Victoria College, 91 Charles Street West, Toronto, ON M5S 1K7, Canada; e‐mail: denis[email protected].

What is a logical constant? The question is addressed in the tradition of Tarski's definition of logical operations as operations which are invariant under permutation. The paper introduces a general setting in which invariance criteria for logical operations can be compared and argues for invariance under potential isomorphism as the most natural characterization of logical operations.

The Enchantment of Words is a study of Wittgenstein's early masterpiece, the Tractatus Logico-Philosophicus. Recent years have seen a great revival of interest in the Tractatus. McManus's study of the work offers novel readings of all its major themes and sheds light on issues in metaphysics, ethics and the philosophies of mind, language, and logic.

How do individuals guide their activities towards some goal? Harry Frankfurt once identified the task of explaining guidance as the central problem in action theory. An explanation has proved to be elusive, however. In this paper, I show how we can marshal empirical research to make explanatory progress. I contend that human agents have a primitive capacity to guide visual attention, and that this capacity is actually constituted by a sub-individual psychological control-system: the executive system. I thus illustrate how we (...) can explain exercises of individual-level guidance by appeal to its sub-individual constitution. This opens up a new avenue for explicating agency. (shrink)

Good explanations are not only true or probably true, but are also relevant to a causal question. Current models of causal explanation either only address the question of the truth of an explanation, or do not distinguish the probability of an explanation from its relevance. The tasks of scenario construction and conversational explanation are distinguished, which in turn shows how scenarios can interact with conversational principles to determine the truth and relevance of explanations. The proposed model distinguishes causal discounting from (...) causal backgrounding , and makes predictions concerning the differential effects of contextual information about alternative explanations on: (a) the kind of mental models constructed; (b) belief revision about probable cause; and (c) the perceived quality of a focal explanation. Four experiments are reported that test these predictions. The significance of the notion of explanatory relevance for research on causal explanation is then discussed. (shrink)

In Kant’s moral theory, we do not have duties to animals, though we have duties with regard to them. I reconstruct Kant’s arguments for several types of duties with regard to animals and show that Kant’s theory imposes far more robust requirements on our treatment of animals than one would expect. Kant’s duties regarding animals are perfect and imperfect; they are primarily but not exclusively duties to oneself; and they condemn not merely cruelty to animals for its own sake, but (...) also, such things as killing them for food when our health does not require it and ingratitude to service animals. Central to understanding these duties is appreciating Kant’s concern for our morally useful emotions, for it is primarily because of the effect that cruelty to animals has on our sympathetic emotions—which greatly help us treat other rational beings appropriately—that we have duties not to be cruel to animals. Yet cruelty and callousness toward animals are not problematic only because they may weaken some of our morally useful emotions. Cruelty and callousness toward animals are problematic also because they oppose our morally useful emotions; these emotions, as part of the perfection of our nature, should be honored, supported, and furthered, unless there are compelling reasons not to do so in particular cases.

Some Kantian ethicists, myself included, have been trying to show how, contrary to popular belief, Kant makes an important place in his moral theory for emotions–especially love and sympathy. This paper confronts claims of Kant that seem to endorse an absence of sympathetic emotions. I analyze Kant’s accounts of different sorts of emotions (“affects,” “passions,” and “feelings”), and different sorts of emotional coolness (“apathy,” “self-mastery,” and “cold-bloodedness”). I focus on the particular way that Kant praises apathy, as “sublime,” in order (...) to argue that his praise of extreme emotional self-control is not incompatible with, but rather complementary to, his praise of sympathy.

There has recently been much interest in the role of attention in controlling action. The role has been mischaracterized as an element in necessary and sufficient conditions on agential control. In this paper I attempt a new characterization of the role. I argue that we need to understand attentional control in order to fully understand agential control. To fully understand agential control we must understand paradigm exercises of agential control. Three important accounts of agential control—intentional, reflective, and goal-represented control—do not (...) fully explain such exercises. I argue that understanding them requires understanding how deployments of visual attention implement flexible occurrent control, or a capacity to flexibly adjust the degree of control that individuals exercise over their actions. While such deployments of attention are neither necessary nor sufficient for exercising agential control, they constitute an attentional skill for controlling action, understanding which is central to fully understanding agential control. We can appreciate its centrality if we appreciate that this attentional skill for controlling action is plausibly crucial to acting non-negligently. (shrink)

This paper investigates the nature and foundation of duties to oneself in Kant's moral theory. Duties to oneself embody the requirement of the formula of humanity that agents respect rational nature in them-selves as well as in others. So understood, duties to oneself are not subject to the sorts of conceptual objections often raised against duties to oneself; nor do these duties support objections that Kant's moral theory is overly demanding or produces agents who are preoccupied with their own virtue. (...) Duties to oneself emerge as an essential and compelling part of Kant's moral theory. (shrink)

In this paper, I explicate Kant’s theory of virtue and situate it within the context of theories of virtue before Kant (such as Aristotle, Hobbes, and Hume) and after Kant (such as Schiller and Schopenhauer). I explore Kant’s notions of virtue as a disposition to do one’s duty out of respect for the moral law, as moral strength in non-holy wills, as the moral disposition in conflict, and as moral self-constraint based on inner freedom. I distinguish between Kant’s notions of (...) virtue and of the good will. I discuss Kant’s duties of virtue (and so particular virtues and vices), the relationships between virtue and happiness and virtue and the emotions, and Kant’s criticisms of his predecessors’ views of virtue. I close with a discussion of Kant and contemporary virtue ethics. Although the paper reflects my own interpretation of Kant, it strives less to argue for a particular thesis about Kant on virtue than to illuminate important aspects of Kant’s theory of virtue.

Providing a principled characterization of the distinction between logical and non-logical expressions is a longstanding issue in the philosophy of logic. In the Logical Syntax of Language, Carnap proposes a syntactic solution to this problem, which aims at grounding the claim that logic and mathematics are analytic. Roughly speaking, his idea is that logic and mathematics correspond to the largest part of science for which it is possible to completely specify by "syntactic" means which sentences are valid and which are (...) not. Despite a renewed interest in the philosophical benefits of analyticity, both inside and outside of Carnap scholarship, Carnap's definition of logical expressions seems to have drawn too little attention. I shall argue that it is worth a second look. More precisely, my aim will be to defend this idea against some technical problems faced by Carnap's way of implementing it and against Quinean attacks on syntax-based conventionalism. Section 1 presents Carnap's definition in the context of Logical Syntax of Language, that is, how exactly the definition works, and why Carnap needs it. In section 2, I review three challenges that have been raised in the literature, and I propose to revise the definition accordingly. I argue that its modified version is immune to the previous challenges, and, to some extent, immune to new challenges as well. In the last section, I suggest that the definition has a philosophical interest of its own, because standard Quinean objections are not as conclusive as one might think when attention is paid to the fact that Carnap requires complete syntactic specification of validities.

The standard relation of logical consequence allows for non-standard interpretations of logical constants, as was shown early on by Carnap. But then how can we learn the interpretations of logical constants, if not from the rules which govern their use? Answers in the literature have mostly consisted in devising clever rule formats going beyond the familiar what follows from what. A more conservative answer is possible. We may be able to learn the correct interpretations from the standard rules, because the (...) space of possible interpretations is a priori restricted by universal semantic principles. We show that this is indeed the case. The principles are familiar from modern formal semantics: compositionality, supplemented, for quantifiers, with topic-neutrality. (shrink)

I consider Kant’s use of claims about “nature’s ends” in his arguments to establish maxims of homosexual sex, masturbation, and bestiality as constituting “unnatural” sexual vices, which are contrary to one’s duties to oneself as an animal and moral being. I argue, first, that the formula of humanity is the principle best suited for understanding duties to oneself as an animal and moral being; and second, that although natural teleology is relevant to some degree in specifying these duties, it cannot (...) play a sufficiently robust role to establish Kant’s conclusion. I also discuss what the formula of humanity (along with warranted attention to natural teleology) suggests about the morality of homosexual sex, masturbation, and bestiality. (shrink)

Over the course of human history, the sciences, and biology in particular, have often been manipulated to cause immense human suffering. For example, biology has been used to justify eugenic programs, forced sterilization, human experimentation, and death camps—all in an attempt to support notions of racial superiority. By investigating the past, the contributors to _Biology and Ideology from Descartes to Dawkins_ hope to better prepare us to discern ideological abuse of science when it occurs in the future. Denis R. (...) Alexander and Ronald L. Numbers bring together fourteen experts to examine the varied ways science has been used and abused for nonscientific purposes from the fifteenth century to the present day. Featuring an essay on eugenics from Edward J. Larson and an examination of the progress of evolution by Michael J. Ruse, _Biology and Ideology_ examines uses both benign and sinister, ultimately reminding us that ideological extrapolation continues today. An accessible survey, this collection will enlighten historians of science, their students, practicing scientists, and anyone interested in the relationship between science and culture. (shrink)

This article addresses the recent reception of Franz Brentano's writings on consciousness. I am particularly interested in the connection established between Brentano's theory of consciousness and higher-order theories of consciousness and, more specifically, the theory proposed by David Rosenthal. My working hypothesis is that despite the many similarities that can be established with Rosenthal's philosophy of mind, Brentano's theory of consciousness differs in many respects from higher-order theories of consciousness and avoids most of the criticisms generally directed to them. This (...) article is divided into eight parts. The first two sections expound the basic outline of Rosenthal's theory, and the third summarizes the principal objections that Rosenthal addresses to Brentano, which I, then, examine in sections 4 and 5. In sections 6 and 7, I discuss Brentano's principle of the unity of consciousness, and in section 8, I consider the scope of the changes that Brentano brings to his theory of consciousness in his later writings, which follow the 1874 publication of Psychology. I then draw the conclusion that Brentano's theory rests on a view of intransitive and intrinsic self-consciousness. (shrink)

Conscious Agency is a major driver of evolution. Artificial Selection (i.e. Conscious Selection by human breeders) was the foil against which Charles Darwin defined Natural Selection. In later work, he extended Artificial Selection to other species. That ability for social (e.g. sexual) selection must have evolved. Jablonka and Ginsburg identify markers of conscious agency, such as Unlimited Associative Learning (UAL), and show that it must have existed at the time of the Cambrian Explosion. To their insights, my commentary argues that (...) the harnessing of stochasticity was also involved in the evolution of the faculty of choice in organisms. (shrink)

A common view about the phenomenology of episodic remembering has it that when we remember a perceptual experience, we can relive or re-experience many of its features, but not its characteristic presence. In this paper, we challenge this common view. We first say that presence in perception divides into temporal and locative presence, with locative having two sides, an objective and a subjective one. While we agree with the common view that temporal and objective locative presence cannot be relived in (...) remembering, we argue that subjective locative presence – the feeling of being immersed in a certain scene – can be so. Our argument for this claim starts by determining independently the underpinning mechanisms of subjective locative presence in quasi-perceptual imagination. These mechanisms are self-projection, imaginative pretence, and attentional focus. We then proceed to establish that they have been found to underpin conscious states of episodic remembering too. We conclude that episodic remembering can bring us to relive the subjective locative presence characteristic of a perceptual experience, and that the common view is mistaken. Our view – ‘mnemonic immersivism’ – has important consequences regarding the relationships between memory and imagination and the phenomenology of episodic remembering. (shrink)

writings, however, reveals a profoundly medieval outlook. Smith is preoccupied with the need to preserve order in society. His scientific methodology emphasises reconciliation with the world we live in rather than investigation of it. He invokes a version of natural law in which the universe is a harmonious machine administered by a providential deity. Nobody is uncared for and, in real happiness, we are all substantially equal. No action is without its appropriate reward – in this life or the next. (...) The social desirability of individual self-seeking activity is ensured by the ‘invisible hand’, that is, the hand of a god who has moulded us so to behave, that the quantity of happiness in the world is always maximised.

ABSTRACTAccording to difference-based models of causal judgement, the epistemic state of the agent should not affect judgements of cause. Four experiments examined opportunity chains in which a physical event enabled a subsequent proximal cause to produce an outcome. All four experiments showed that when the proximal cause was a human action, it was judged as more causal if the agent was aware of his opportunity than if he was not or if the proximal cause was a physical event. The first (...) two experiments showed that these preferences could not be explained in terms of differences in perceived conditional probability, social controllability or perceptions of the causal sequence as forming a single unit. The third experiment showed that awareness affected the perceived deliberateness with which the action brought the outcome about but not its perceived voluntariness. The fourth experiment showed that... (shrink)

Wittgenstein is arguably the greatest philosopher of the last hundred years and scepticism is one of the central problems that modern philosophy faces. This collection is the first to be devoted to an examination of how that great philosopher's work bears on this fundamental philosophical problem. Wittgenstein's reaction to scepticism is complex, articulating both a sense that sceptical problems are ultimately unreal and a sense that scepticism teaches us something about the fundamental character of the human predicament. The essays, specially (...) written for this collection by distinguished philosophers and commentators on Wittgenstein, explore that reaction, addressing, in particular, scepticism about the existence of the external world and of other minds. In doing so, it explores issues not only in theory of knowledge but also in metaphysics, the philosophy of mind, language, perception and literature, as well as raising questions about the nature of philosophy itself. Several of the papers address the work of Stanley Cavell, perhaps the most influential commentator on the work of Wittgenstein, and Cavell replies in the final pieces to four of those papers. This collection is essential reading for students and scholars of Wittgenstein and anyone interested in the debate surrounding scepticism. (shrink)

Europeans seeking to understand tribal arts face obvious problems of comprehending the histories, values, and ideas of vastly remote cultures. In this respect the issues faced in understanding tribal art (or folk art, primitive art, traditional art, third or fourth-world art — none of these designations is ideal) are not much different from those encountered in trying to comprehend the distant art of “our own” culture, for instance, the art of medieval Europe. But in the case of tribal or so-called (...) primitive art, there are special complications. First, objects of tribal art are sometimes so strange to us that we cannot tell immediately whether they are intended to be works of art (or some local analogue of what we would call art) at all.1An African head-rest I once came across had an odd, extravagant extrusion which made the whole piece reminiscent of Arp. It seemed to my baffled, ignorant eyes to be much more than a mere head-rest, but I couldn’t tell what more it was supposed to be. Maybe that extension on the side of the object had some purely utilitarian function, acting as a handle, or perhaps it was a natural part of the original block of wood, left there merely because it looked nice to the eye of the carver. Though the head-rest seemed beautiful, I still don’t know if I was admiring as an essentially expressive object some simple item of practical use, or something that combined expression and utility.

By means of a consideration of Whitman (1998) the present paper considers the meanings of ‘Panglossianism’ and the relation between group and individual levels in evolution. It establishes the connection between the Panglossian policy prescription of laissez-faire and the mistaken evolutionary theory of group selection. Analysis of the passages in Hayek cited by Whitman shows that, once these passages are taken in context, and once the appropriate meaning of the term ‘Panglossian’ has been clarified, they fail to defend Hayek from (...) this charge, but, on the contrary, confirm that Hayek was, indeed, ‘a Panglossian evolutionary theorist’.

Though Heidegger’s Being and Time is often cited as one of the most important philosophical works of the last hundred years, its Division Two has received relatively little attention. This outstanding collection corrects that, examining some of the central themes of Division Two and their wide-ranging and challenging implications. An international team of leading philosophers explore the crucial notions that articulate Heidegger’s concept of authenticity, including death, anxiety, conscience, guilt, resolution and temporality. In doing so, they clarify the bearing of (...) Division Two’s reflections on our understanding of intentionality, normativity, responsibility, autonomy and selfhood. These discussions raise important questions about how we may need to rethink the morals of Division One of Being and Time , the broader project to which that book was devoted, the shaping influence of figures such as Aristotle and Kierkegaard, as well as Heidegger’s relationship with his contemporaries and successors. Essential reading for students and scholars of Heidegger’s thought, and anyone interested in key debates in phenomenology, ethics, metaphilosophy and philosophy of mind.

What is a logical constant? In which terms should we characterize the meaning of logical words like “and”, “or”, “implies”? An attractive answer is: in terms of their inferential roles, i.e. in terms of the role they play in building inferences. More precisely, we favor an approach, going back to Dosen and Sambin, in which the inferential role of a logical constant is captured by a double line rule which introduces it as reflecting structural links (for example, multiplicative conjunction reflects (...) comma on the right of the turnstyle). Rule-based characterizations of logical constants are subject to the well known objection of Prior’s fake connective, tonk. We show that some double line rules also give rise to such pseudo logical constants. But then, we are able to find a property of a double line rules which guarantee that it defines a genuine logical constant. Thus we provide an alternative answer to Belnap’s requirement of conservatity in terms of a local requirement on double line rules. (shrink)

From an enactive approach to human activity, we suggest that the use of appearance-enhancing drugs is better explained by the sense-making related to body image rather than the cognitive evaluation of social norms about appearance and consequent psychopathology-oriented approach. After reviewing the main psychological disorders thought to link body image issues to the use of appearance-enhancing substances, we sketch a flexible, dynamic and embedded account of body image defined as the individual’s propensity to act and experience in specific situations. We (...) show how this enacted body image is a complex process of sense-making that people engage in when they are trying to adapt to specific situations. These adaptations of the enacted body image require effort, perseverance and time, and therefore any substance that accelerates this process appears to be an easy and attractive solution. In this enactive account of body image, we underline that the link between the enacted body image and substance use is also anchored in the history of the body’s previous interactions with the world. This emerges during periods of upheaval and hardship, especially in a context where athletes experience weak participatory sense-making in a sport community. We conclude by suggesting prevention and intervention designs that would promote a safe instrumental use of the body in sports and psychological helping procedures for athletes experiencing difficulties with substances use and body image.

Paul Boghossian has pointed out a ’circularity problem’ for dispositionalist theories of meaning: as a result of the holistic character of belief fixation, one cannot identify someone’s meaning such and such with facts of the form S is disposed to utter P under conditions C, without C involving the semantic and intentional notions that such a theory was to explain. Alex Miller has recently suggested an ’ultra‐sophisticated dispositionalism’ (modelled on David Lewis’s well known version of functionlism) and has argued that (...) this version of dispositionalism escapes Boghossian’s ’circularity problem’. Miller argues, nonetheless, that another of Boghossian’s criticisms of dispositionalism, ’the infinity problem’ still applies to this ’ultra‐sophisticated dispositionalism’: C will still draw upon a potential infinity of mediating background clusters of belief. The present paper argues that the feature that ’the infinity problem’ presents as problematic is a feature of a host of familiar explanations. Our fundamental difficulty in this area is not our inability to understand how a more general model can be applied to a particular domain (the intentional understood as dispositional) but our failure to understand that general model itself (dispositional explanation).

Pour certains interprètes des Recherches philosophiques , Wittgenstein souscrit à l'idée que l'emploi d'un langage est une institution sociale et que suivre une règle est nécessairement une pratique partagée ; d'autres estiment au contraire — à mon avis avec raison — qu'il admet la possibilité d'un langage parlé par un seul individu et des règles non communes. Je défends l'interprétation selon laquelle la question importante dans les Recherches n'est pas tellement de savoir si un idiolecte est possible que de savoir (...) ce qui découle, pour nos concepts de signification, de compréhension linguistique et de « suivre une règle », du fait que la communication verbale soit — comme c'est normalement le cas — une pratique commune.According to some interpreters of the Philosophical Investigations , Wittgenstein thinks that language-use is a social institution and that rule following is a shared practice. Others hold the opposite view and rightly so. They argue that Wittgenstein thinks there could be a language which is spoken by only one individual and unshared rules.

After sketching some aspects of truthmaker doctrines and "truthmaker projects", and canvassing some prima facie objections to the latter, I turn to an issue which might seem to involve confusion about the nature of character of truthmakers if such there be, viz for statements of identity and (specially) distinctness. The real issue here is versions of the Identity of Indiscernibles. I discuss ways of discriminating versions, which are almost certainly true but trivial, which almost certainly substantive but false, and explore (...) an interesting intermediate possibility which might if developed yield a plausibly true yet not-entirely-trivial version of the doctrine: it is equivalent to what I call "the Denial of Bare Distinctness".

Many feminist philosophers have been highly critical of Kant’s ethics, either because of his rationalism or because of particular claims he makes about women in his writings on anthropology and political philosophy. In this paper, I call attention to the aspects of Kant’s ethical theory that make it attractive from a feminist standpoint. Kant’s duties to oneself are rich resource for feminism. These duties require women to act in ways that show respect for themselves as rational human agents by, e.g., (...) avoiding servility, self-deception, self-mutilation, and sexual self-degradation, and cultivating their natural talents (as well as their virtue). Duties to others demand that other people treat women respectfully by requiring that they avoid mocking, degrading, or acting arrogantly toward others. Indeed, even when one sets out to promote others’ happiness, Kant’s ethics requires that one not act paternalistically. Kant’s ethics insists that every rational agent recognize the equality and dignity of all rational agents. Thus, it pushes women to respect themselves and to demand respect from others; and it pushes men to respect women as a basic moral requirement. (shrink)

This paper explores how a virtuous Kantian agent would regard and express her sexuality. I argue both that Kant has a rich account of virtue, and that a virtuous Kantian agent should view her sexuality as a good thing–as an important aspect of her animal nature. On my view, the virtuous agent does not seek to suppress her sexuality, but rather to find modes and contexts for its expression that allow the agent to maintain her self-respect and to avoid degrading (...) others. The paper begins by considering reasons, grounded in Kant’s texts, why one might reasonably think that Kant has a pejorative view of sexuality, and only the thinnest account of virtue, to offer. I then aim to correct this picture by more carefully and fully exploring Kant’s work, putting his apparently negative comments about sex, and apparently narrow account of virtue, in their proper context. I also dispute—based on Kant’s own principles—some of Kant’s claims about homosexual sex and masturbation as violations of duties to oneself as an animal and moral being. Finally, I conclude the paper with an account of the virtuous Kantian agent’s proper attitude toward her sexuality. (shrink)

This article discusses some difficulties of the theory of color propounded by Meinong in his Re-marks on the Color Solid and the Mixture Law of 1903. First, I argue that Meinong’s geometrical approach faces at least three sets of difficulties related to the following assumptions: colors pos-sess a “nature” that can be grasped through intuition; they are separated from each other by continua in color space; there are an infinite number of a priori relations between colors. Second, I confront the (...) geometrical approach with Wittgenstein’s grammatical approach, contending that the latter escapes these difficulties. (shrink)

Sydney Shoemaker argues that time without change is possible, but begs the question by assuming an, in effect, Newtonian absolute time, that 'flows equably' in a region in which there is no change and in one in which there is. An equally possible, relativist, assumption, consistent, it seems, with relativity theory, is that where nothing changes there is no time flow, though there may be elsewhere, where there is change. Such an assumption would require some revision of uncritical common thought (...) about time. Aristotle argues that there is no time without change but that time is not change. His arguments for the latter can be faulted both internally and again in terms of the same relativist assumption. From the Physics we can derive, though Aristotle himself did not, an argument that time is to change as geometrical space is to body: the thing itself in abstraction. (shrink)

The dual character of invariance under transformations and definability by some operations has been used in classical works by, for example, Galois and Klein. Following Tarski, philosophers of logic have claimed that logical notions themselves could be characterized in terms of invariance. In this article, we generalize a correspondence due to Krasner between invariance under groups of permutations and definability in L∞∞ so as to cover the cases that are of interest in the logicality debates, getting McGee’s theorem about quantifiers (...) invariant under all permutations and definability in pure L∞∞ as a particular case. We also prove some optimality results along the way, regarding the kinds of relations which are needed so that every subgroup of the full permutation group is characterizable as a group of automorphisms.
