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.walsh@utoronto.ca.

Sylvia Walsh explores Kierkegaard's understanding of Christianity and the existential mode of thinking theologically appropriate to it in the context of the ...
The Modern Philosophical Revolution breaks new ground by demonstrating the continuity of European philosophy from Kant to Derrida. Much of the literature on European philosophy has emphasized the breaks that have occurred in the course of two centuries of thinking. But as David Walsh argues, such a reading overlooks the extent to which Kant, Hegel, and Schelling were already engaged in the turn toward existence as the only viable mode of philosophizing. Where many similar studies summarize individual thinkers, this (...) book provides a framework for understanding the relationships between them. Walsh thus dispels much of the confusion that assails readers when they are only exposed to the bewildering range of positions taken by the philosophers he examines. His book serves as an indispensable guide to a philosophical tradition that continues to have resonance in the post-modern world. (shrink)
According to Aristotelian essentialism, the nature of an organism is constituted of a particular goal-directed disposition to produce an organism typical of its kind. This paper argues—against the prevailing orthodoxy—that essentialism of this sort is indispensable to evolutionary biology. The most powerful anti-essentialist arguments purport to show that the natures of organisms play no explanatory role in modern synthesis biology. I argue that recent evolutionary developmental biology provides compelling evidence to the contrary. Developmental biology shows that one must appeal to (...) the capacities of organisms to explain what makes adaptive evolution adaptive. Moreover, the specific capacities in question are precisely those that, according to Aristotle, constitute the nature of an organism.

We distinguish dynamical and statistical interpretations of evolutionary theory. We argue that only the statistical interpretation preserves the presumed relation between natural selection and drift. On these grounds we claim that the dynamical conception of evolutionary theory as a theory of forces is mistaken. Selection and drift are not forces. Nor do selection and drift explanations appeal to the (sub-population-level) causes of population level change. Instead they explain by appeal to the statistical structure of populations. We briefly discuss the implications (...) of the statistical interpretation of selection for various debates within the philosophy of biologythe `explananda of selection' debate and the `units of selection' debate.

Synaesthesia is considered a rare perceptual capacity, and one that is not capable of cultivation. However, meditators report the experience quite commonly, and in questionnaire surveys, respondents claimed to experience synaesthesia in 35% of meditation retreatants, in 63% of a group of regular meditators, and in 86% of advanced teachers. These rates were significantly higher than in nonmeditator controls, and displayed significant correlations with measures of amount of meditation experience. A review of ancient texts found reports suggestive of synaesthesia in (...) advanced meditators from India and China. These findings suggest that synaesthesia may be cultivated by meditation, and that laboratory studies of meditators could be rewarding. (shrink)
There are two competing interpretations of the modern synthesis theory of evolution: the dynamical (also know as ‘traditional’) and the statistical. The dynamical interpretation maintains that explanations offered under the auspices of the modern synthesis theory articulate the causes of evolution. It interprets selection and drift as causes of population change. The statistical interpretation holds that modern synthesis explanations merely cite the statistical structure of populations. This paper offers a defense of statisticalism. It argues that a change in trait frequencies (...) in a population can be attributed only to selection or drift against the background of a particular statistical description of the population. The traditionalist supposition that selection and drift are description‐independent causes of population change leads the dynamical interpretation into a dilemma: it must face a contradiction or accept the loss of explanatory power.

David Lewis insists that restrictivist composition must be motivated by and occur due to some intuitive desiderata for a relation R among parts that compose wholes, and insists that a restrictivist’s relation R must be vague. Peter van Inwagen agrees. In this paper, I argue that restrictivists need not use such examples of relation R as a criterion for composition, and any restrictivist should reject a number of related mereological theses. This paper critiques Lewis and van Inwagen (and others) on (...) their respective mereological metaphysics, and offers a Golden Mean between their two opposite extremes. I argue for a novel account of mereology I call Modal Mereology that is an alternative to Classical Mereology. A modal mereologist can be a universalist about the possible composition of wholes from parts and a restrictivist about the actual composition of wholes from parts. I argue that puzzles facing Modal Mereology (e.g., puzzles concerning Cambridge changes and the Problem of the Many, and how to demarcate the actual from the possible) are also faced in similar forms by classical universalists. On my account, restricted composition is rather motivated by and occurs due to a possible whole’s instantiating an actual type. Universalists commonly believe in such types and defend their existence from objections and puzzles. The Modal Mereological restrictivist can similarly defend the existence of such types (adding that such types are the only wholes) from similar objections and puzzles. (shrink)

Thought experiments have played a pivotal role in many debates within ethics—and in particular within applied ethics—over the past 30 years. Nonetheless, despite their having become a commonly used philosophical tool, there is something odd about the extensive reliance upon thought experiments in areas of philosophy, such as applied ethics, that are so obviously oriented towards practical life. Herein I provide a moderate defence of their use in applied philosophy against those three objections. I do not defend all possible uses (...) of thought experiments but suggest that we should distinguish between legitimate and illegitimate uses. Their legitimate uses are determined not so much by the modal content of any actual thought experiment itself, but by the extent to which the argument in which it is nested follows basic tenets of informal logic and respects the fundamental contingency of applied ethical problems. In pursuing these ideas, I do not so much provide a set of criteria for their legitimate use, but more modestly present two significant ways in which their use can go awry. (shrink)
According to a prominent view of evolutionary theory, natural selection and the processes of development compete for explanatory relevance. Natural selection theory explains the evolution of biological form insofar as it is adaptive. Development is relevant to the explanation of form only insofar as it constrains the adaptation-promoting effects of selection. I argue that this view of evolutionary theory is erroneous. I outline an alternative, according to which natural selection explains adaptive evolution by appeal to the statistical structure of populations, (...) and development explains the causes of adaptive evolution at the level of individuals. Only together can a statistical theory of selection and a mechanical theory of development explain why populations of organisms comprise individuals that are adapted to their conditions of existence.

How do people understand questions about cause and prevent? Some theories propose that people affirm that A causes B if A's occurrence makes a difference to B's occurrence in one way or another. Other theories propose that A causes B if some quantity or symbol gets passed in some way from A to B. The aim of our studies is to compare these theories' ability to explain judgements of causation and prevention. We describe six experiments that compare judgements for causal (...) paths that involve a mechanism, i.e. a continuous process of transmission or exchange from cause to effect, against paths that involve no mechanism yet a change in the cause nevertheless brings about a change in the effect. Our results show that people prefer to attribute cause when a mechanism links cause to effect. In contrast, prevention is sensitive both to the presence of an interruption to a causal mechanism and to a change in the outcome in the absence of a mechanism. In this sense, ‘prevent’ means something different than ‘cause not'. We discuss the implications of our results for existing theories of causation. (shrink)
According to historical theories of biological function, a trait's function is determined by natural selection in the past. I argue that, in addition to historical functions, ahistorical functions ought to be recognized. I propose a theory of biological function which accommodates both. The function of a trait is the way it contributes to fitness and fitness can only be determined relative to a selective regime. Therefore, the function of a trait can only be specified relative to a selective regime. Apart (...) from its desirable pluralism, only this view of relational function can support the function/accident and function/malfunction distinctions commonly thought to be part of the concept of function. Furthermore, only relational function correctly characterizes the explanatory consequences of function attributions in evolutionary biology. (shrink)
We outline our central reasons for pursuing the project of equality studies and some of the thinking we have done within an equality studies framework. We try to show that a multi-dimensional conceptual framework, applied to a set of key social contexts and articulating the concerns of subordinate social groups, can be a fruitful way of putting the idea of equality into practice. Finally, we address some central questions about how to bring about egalitarian social change.
The Units of Selection debate is a dispute about the causes of population change. I argue that it is generated by a particular `dynamical'' interpretation of natural selection theory, according to which natural selection causes differential survival and reproduction of individuals and natural selection explanations cite these causes. I argue that the dynamical interpretation is mistaken and offer in outline an alternative, `statistical'' interpretation, according to which natural selection theory is a fancy kind of `bookkeeping''. It explains by citing the (...) statistical structure of a population and not by citing the causes of survival and reproduction. From the perspective of the statistical interpretation there is no substantive Units of Selection issue. (shrink)
Two puzzles with regard to the Kritik der reinen Vernunft (KrV) are incongruent counterparts and causality. In De mundi sensibilis atque intelligibilis forma et principiis (MSI), Kant indicates that the experience of things like left and right hands, so-called incongruent counterparts, involve certain pure intuitions, and hence constitute one line of evidence for the claim that the concept of space itself is a pure intuition. In KrV, Kant again argues that the concept of space itself is a pure intuition, but (...) does not cite the experience of incongruent counterparts as evidence for this claim. Since there is ostensibly nothing in KrV which tells against the existence of the experiences of incongruent counterparts, the natural question is: “Why, in KrV, does Kant not cite the experience of incongruent counterparts as evidence for the claim that the concept of space is a pure intuition?” The problem with causality is as follows. One of the most primary and basic claims of KrV is that empirical experience is structured by non-empirical concepts, such as substantiality and causality. In a portion of KrV entitled the Transcendental Deduction, Kant gives section 20 the heading “All sensible intuitions stand under the categories, as conditions under which alone their the manifold can come together in one consciousness”. Since categories are those concepts which structure empirical experience, section 20 has demonstrated that all sensible intuitions are subject to substantiality and causality. However, there is a later portion of KrV entitled the Second Analogy with the heading “Principle of temporal sequence according to the law of causality: All alterations occur in accordance with the law of the connection of cause and effect”. Thus, the natural question is: “What does the Second Analogy demonstrate about causality which the Transcendental Deduction did not already demonstrate about causality?”. (shrink)
I argue that recent advances in developmental biology demonstrate the inadequacy of suborganismal mechanism. The category of the organism, construed as a ’natural purpose’ should play an ineliminable role in explaining ontogenetic development and adaptive evolution. According to Kant the natural purposiveness of organisms cannot be demonstrated to be an objective principle in nature, nor can purposiveness figure in genuine explain. I attempt to argue, by appeal to recent work on self-organization, that the purposiveness of organisms is a natural phenomenon (...) and, by appeal to the apparatus of invariance explanation, that biological purposiveness provides genuine, ineliminable biological explanations.

The Quietist affair at the end of the seventeenth century has much to teach us about theories of the will in the period. Although Bossuet and Fénelon are the names most famously associated with the debate over the Quietist conception of pure love, Malebranche and his erstwhile disciple Lamy were the ones who debated the deep philosophical issues involved. This paper sets the historical context of the debate, discusses the positions as well as the arguments for and against them, and (...) opens up investigation of important material that is all but ignored in the English literature and only incompletely addressed in the French.

In this paper I draw on the French philosopher Michel Foucault for a viewpoint on aspects of EBM. This means that I develop his idea of the spaces occupied by disease. I give much of the paper to only one of these spaces, the space of perception of disease, in order to major on the medical gaze, one of Foucault’s best-known contributions to the philosophy of medicine. As I explain what I mean by each of the spaces of disease, I (...) configure EBM into this space. The conscientious, explicit, and judicious use of current best evidence in making decisions about the care of individual patients. Evidence-based clinical practice requires integration of individual clinical expertise and patient preferences with the best available external clinical evidence from systematic research and consideration of available resources. EBM can be considered a subcategory of evidence-based healthcare, which also includes other branches of health-care practice such as evidence-based nursing or evidence-based physiotherapy. EBM subcategories include evidence-based surgery and evidence-based cardiology (Guyatt et al. 2008 , 783). (shrink)
Recently among analytic political philosophers there has been a considerable revival of interest in the normative evaluation of the market and of economic processes more generally. While not rejecting markets in toto , philosophers such as Elizabeth Anderson and Amartya Sen have raised questions about the proper range of the market, explored the role of normative considerations in economic decision-making and raised doubts about the view that normative constraints are never legitimately placed on economic activity. In this article I experience (...) the relevance to such explorations of the economic casuistry of the medieval schoolmen.

Wide content and individualist approaches to the individuation of thoughts appear to be incompatible; I think they are not. I propose a criterion for the classification of thoughts which captures both. Thoughts, I claim, should be individuated by their teleological functions. Where teleological function is construed in the standard way - according to the aetiological theory - individuating thoughts by their function cannot produce a classification which is both individualistic and consistent with the principle that sameness of wide content is (...) sufficient for sameness of psychological state. There is, however, an alternative approach to function, the relational theory, which is preferable on independent grounds. A taxonomy of thoughts based on these functions reconciles wide content with individualism. One consequence of individuating thoughts in this way is that intentional content is context sensitive. I discuss some of the implications of context sensitive content. (shrink)
The axiom of comparability has been a fundamental part of mathematical choice theory from its beginnings. This axiom was a natural first assumption for a theory of choice originally constructed to explain decision making where other assumptions such as continuous divisibility of choice spaces could legitimately also be made. Once the generality of application of formal choice theory becomes apparent, it also becomes apparent that both continuity assumptions and the axiom of comparability may be unduly restrictive and lead to the (...) neglect of decision situations which are important and which can be handled on a modified axiom set. These considerations bear on the philosophical analysis of the concept of rational decision. (shrink)
This essay takes as its focus Japanese philosopher Nishida Kitar? (1870?1945) and his seminal first text, An Inquiry into the Good (or in Japanese zen no kenky?). Until now scholarship has taken for granted the predominantly Buddhist orientation of this text, centered around an analysis of the central concept of ?pure experience? (junsui keiken) as something Nishdia extrapolates from his early experience of Zen meditation. However, in this paper I will present an alternative and more accurate account of the origins (...) of this important work, a text often seen as marking the beginning of Modern Japanese philosophy. I will show that while Buddhism is an important part of Nishida's early intellectual development, there is ample biographical and textual evidence to suggest that zen no kenky? is at its core a text which attempts to solve key ethical problems via a modern interpretation of concepts drawn from the Confucian tradition. This analysis thus places the concept of ?Conduct? (koi), rather than ?pure experience?, at the center of the text, suggesting that ethics, rather than metaphysics, is the core theme of the book.

Much of the Mill-Whewell dispute was purely verbal, but much was not. Mill did not understand Whewell; the true character of the non-verbal aspect of the controversy emerges only upon adequate analysis of Whewell's actual position. Such analysis shows that Mill's objections to Whewell were misdirected, although suggestive of other which might, if prosecuted, carry. Ultimately, the dispute has to do with the given; neither man gives an adequate account of it. For this reason, the controversy cannot be resolved definitively (...) in favor of either of them.

: This essay discusses the implications of Irigaray's readings of the Antigone in the construction of a feminist ethics. By focusing on the gaps and intersections between Lacanian psychoanalysis and Hegelian phenomenology as formulative of Irigaray's eventual call for an ethics of sexual difference, I emphasize the inevitability of rethinking the functions of historicity, femininity, and maternity in the formation of new models of intersubjectivity.
Psychological individualism is motivated by two taxonomic principles: (i) that psychological states are individuated by their causal powers, and (ii) that causal powers supervene upon intrinsic physiological state. I distinguish two interpretations of individualism--the 'orthodox' and the 'alternative'--each of which is consistent with these motivating principles. I argue that the alternative interpretation is legitimately individualistic on the grounds that it accurately reflects the actual taxonomic practices of bona fide individualistic sciences. The classification of homeobox genes in developmental genetics provides an (...) illustration. When applied to the taxonomy of psychological kinds, alternative individualism has some surprising consequences. In particular, externalist taxonomies of thought are consistent with the alternative interpretation, and hence consistent with individualism. I conclude, on this basis, that the individualism/externalism dispute which has long preoccupied philosophy of psychology is an empty one. (shrink)
We reply to discussions of Equality: From Theory to Action by Harry Brighouse, Joanne Conaghan, Cillian McBride and Stuart White. We find many of their points helpful and treat them as a useful contribution to a continuing dialogue on egalitarianism.
It is generally not recognized that Whewell's conception of necessary truth evolved only gradually; his early statements are misleading. For this reason, and because of certain peculiarities in his expository style over his publishing history, he is commonly thought to have used the term "necessary" in the sense of "absolutely necessary". I argue that, on the contrary, the term is essentially relational in his mature view. This conclusion leads, in turn, to a re-interpretation of his doctrine of "fundamental ideas". Here (...) I argue that the crux of his position is that cognitive principles which are initially regulative become, through invention, repeated employment, and stipulative definition, constitutive ones.

Lea & Webley (L&W) provide two alternative biological accounts of human monetary motivations, the Tool Theory and the Drug Theory. They argue that both are required for an adequate explanation. I explore the applicability of these models to philosophical discussions of how we might justify such motivations. I argue their approach is not entirely satisfactory for normative questions, since it precludes the possibility of rational non-instrumental attitudes towards money. (Published Online April 5 2006).
In this paper, I develop an argument for the thesis that ‘maximality is extrinsic’, on which a whole physical object is not a whole of its kind in virtue of its intrinsic properties. Theodore Sider has a number of arguments that depend on his own simple argument that maximality is extrinsic. However, Peter van Inwagen has an argument in defence of his Duplication Principle that, I will argue, can be extended to show that Sider's simple argument fails. However, van Inwagen's (...) argument fails against a more complex, sophisticated argument that maximality is extrinsic. I use van Inwagen's own commitments to various forms of causation and metaphysical possibility to argue that maximality is indeed extrinsic, although not for the mundane reasons that Sider suggests. I then argue that moral properties are extrinsic properties. Two physically identical things can have different moral properties in a physical world. This argument is a counterexample to a classical ethical supervenience idea (often attributed to G.E. Moore) that if there is identity of physical properties in a physical world, then there is identity in moral properties as well. I argue moral value is ‘border sensitive’ and extrinsic for Kantians, utilitarians, and Aristotelians. (shrink)
