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.

Is an appropriate causal connection to the past experience it represents a necessary condition for a mental state to qualify as an episodic memory? For some years this issue has been the subject of an intense debate between the causalist theory of episodic memory (CTM) and the simulationist theory of episodic memory (STM). This paper aims at exploring the prospects for an embodied approach to episodic memory and assessing the potential case for causalism that could be founded on it. In (...) a critical section, it argues that the empirical data to which STM appeals are both incomplete and inconclusive, and on closer examination even provide support for a proceduralist version of CTM. In a constructive section, it elaborates on the notion of a necessary causal connection in terms of particular procedural patterns acquired at encoding and operative at retrieval, grounding this move on recent empirical data about eye movements in mnemonic mental imagery.

This paper examines a doctrine which David Lewis has called 'Humean Supervenience' (hereafter 'HS'), and a problem which certain imaginary cases seem to generate for HS. They include rotating perfect spheres or discs, and flowing rivers, imagined as composed of matter which is perfectly homogeneous right down to the individual points. Before considering these examples, I shall introduce the doctrine they seem to challenge.

What is Life? This is the question asked by Denis Noble in this very personal and at times deeply lyrical book. Noble is a renowned physiologist and systems biologist, and he argues that the genome is not life itself: to understand what life is, we must view it at a variety of different levels, all interacting with each other in a complex web. It is that emergent web, full of feedback between levels, from the gene to the wider environment, (...) that is life. (shrink)

This is a survey article in which I explore some important recent work on the topic in question, Kant’s formula of the end in itself (or “formula of humanity”). I first provide an overview of the formulation, including what the formula seems roughly to be saying, and what Kant’s main argument for it seems to be. I then call the reader’s attention to a variety of questions one might have about the import of and argument for this formula, alluding to (...) some of the works in which philosophers have recently raised or tried to answer these questions. Then, for the bulk of the paper, I focus my discussion on two issues of contention: the identity of the “end in itself” that the formula refers to, and the relation between the value of the end in itself and the value of other ends. I do not attempt to argue for a particular position of my own regarding these issues. Instead, I explain a number of the more interesting or influential recent attempts to answer these questions, compare these approaches in various ways, draw implications from them, and raise concerns about some of them. I also suggest that an important link connects the question about the identity of the end in itself and the question about the relation between the value of the end in itself in relation to the value of other ends: How one answers these questions commits one to a position on the thorny issue of whether, how, and how fully, autonomy is manifested through empirical (not simply pure) practical reason.

In recent years, there has been an increasing interest among philosophers of memory in the questions of how to characterize and to account for the temporal phenomenology of episodic memory. One prominent suggestion has been that episodic memory involves a feeling of pastness, the elaboration of which has given rise to two main approaches. On the intentionalist approach, the feeling of pastness is explained in terms of what episodic memory represents. In particular, Fernández has argued that it can be explained (...) in terms of memory representing itself as being caused by a past perceptual experience. On the metacognitive approach, which we have recently developed in, the feeling of pastness results from the monitoring and interpretation of the processing features of episodic remembering. In this paper, we show that the metacognitive approach should be preferred over the intentionalist approach. We argue that intentionalism, and Fernández’ causal self-referential view in particular, ultimately fail as accounts of the feeling of pastness. The difficulties faced by intentionalism allows us to single out three constraints that any satisfactory account of the temporal phenomenology of episodic remembering needs to meet. We conclude by arguing that the metacognitive view satisfies those constraints in a neat way, and as such, that it should be preferred over intentionalism. (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.

Several notions of computability-theoretic reducibility between [Formula: see text] principles have been studied. This paper contributes to the program of analyzing the behavior of versions of Ramsey’s Theorem and related principles under these notions. Among other results, we show that for each [Formula: see text], there is an instance of RT[Formula: see text] all of whose solutions have PA degree over [Formula: see text] and use this to show that König’s Lemma lies strictly between RT[Formula: see text] and RT[Formula: see (...) text] under one of these notions. We also answer two questions raised by Dorais, Dzhafarov, Hirst, Mileti, and Shafer on comparing versions of Ramsey’s Theorem and of the Thin Set Theorem with the same exponent but different numbers of colors. Still on the topic of the effect of the number of colors on the computable aspects of Ramsey-theoretic properties, we show that for each [Formula: see text], there is an [Formula: see text]-coloring [Formula: see text] of [Formula: see text] such that every [Formula: see text]-coloring of [Formula: see text] has an infinite homogeneous set that does not compute any infinite homogeneous set for [Formula: see text], and connect this result with the notion of infinite information reducibility introduced by Dzhafarov and Igusa. Next, we introduce and study a new notion that provides a uniform version of the idea of implication with respect to [Formula: see text]-models of RCA0, and related notions that allow us to count how many applications of a principle [Formula: see text] are needed to reduce another principle to [Formula: see text]. Finally, we fill in a gap in the proof of Theorem 12.2 in Cholak, Jockusch, and Slaman. (shrink)

How can we argue, from neural facts, that representational states exhibit some specific representational structure? This paper approaches the question through a case study on the priority map-mechanism that underlies our capacity to orient visual attention. Computational models from cognitive neuroscience describe this mechanism as operating over neural topographic structures. These neural structures exhibit the functional profile of topographic representational structure. I argue that this fact warrants attributing topographic structure to the priority map mechanism’s representational states.

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)

This paper explores a variety of kinds of apparent disagreement of which it may be held that they involve failure to disagree in that, at least in some broad sense, the disputants use the same words to express different meanings or concepts. It is argued that it is hard to rebut the claim that some apparent disagreements about personal identity fall into a particular sub-category of this broad type. I conclude both that a "constrained" relativism which I call "quasi-relativism" is (...) appropriate in regard to some central personal-identity debates, and also that, in order to avoid the lamentable conclusion that there is no real disagreement at all in these debates, we should embrace the idea that there is a non-cognitive element in personal identity claims, in virtue of the tight conceptual relations between personal identity claims and value claims of various kinds.

The authors analyze Takhtajan's system of classification of the Angiosperms in relation to the principles of evolutionary and cladistic systematics. It is shown that Takhtajan belongs to the evolutionary school: he identifies the ancestors of some taxa, he accepts polytomous branching and he groups taxa on the basis of primitive as well as derived character states. Takhtajan's notion of weighted similarity does not appear to be based on objective criteria, when determining the weight and evolutionary status of characters.After a summary (...) of the modifications brought out by Takhtajan in his 1980 version, the weak and strong points of evolutionary systems as a whole are emphasized. In these, the delimitation of taxa and their filiation are difficult to refute since they do not rely on precise criteria, which would ensure continuity and uniformity within a given system. However, these systems have some flexibility, which allows them to incorporate readily new information, a feature unfortunately missing in cladistic classifications. In fact, while it does have weaknesses from a theoretical point of view, the system of Takhtajan gives us an idea of flowering plants phylogeny that appears to be one of the most complete at the present time from both analytical and synthetic standpoints.

The work of Hubert Dreyfus interweaves productively ideas from, among others, Heidegger and Wittgenstein. A central element in Dreyfus' hugely influential interpretation of the former is the proposal that, if we are to—in some sense—'make sense' of intentionality, then we must recognize what Dreyfus calls the 'background'. Though Dreyfus has, over the years, put the notion of the 'background' to a variety of philosophical uses,1 considerations familiar from the literature inspired by Wittgenstein's reflections on rule-following have played an important role (...) in motivating the case for believing that we need to recognize the 'background' and thus also in identifying precisely what it is about the intentional that supposedly needs to be 'made sense of'. Dreyfus argues that what he calls 'representationalism' will land us with an unstoppable 'regress of rules'. In this paper, I first argue that there are actually two different arguments that Dreyfus invokes; I then go on to evaluate quite how, in the light of the problems that those arguments reveal, our position might be thought to be improved by our recognizing the 'background'. Given that various philosophical positions designed to deal with these problems have emerged within the Wittgensteinian literature, an obvious question to ask is whether the position that Dreyfus would have us adopt is essentially one of those positions. If it isn't, then how does it differ? There is surely a variety of ways in which such a comparison might be carried out and what I offer is only one. I argue that if, through a recognition of the 'background', we are thought to have acquired solutions to those problems, then it's not at all clear that the supposed solutions that emerge work. So I explore instead the possibility that that recognition forms part of an attempt to 'dissolve' those problems. In order to bring some clarity to that possibility I consider a number of different ways in which Dreyfus' proposals might be interpreted by drawing on ideas set out by John McDowell (and I suggest that his view of one of the 'regress' arguments is anticipated by Heidegger himself). I then identify and assess some of the consequences of adopting such McDowellian readings. My sense is that Dreyfus is on the side of the angels, so to speak. But if what is right in his proposals is to become clear, and if he is to be spared some obvious objections that those proposals may elicit, we need to be clear about just what kind of contribution those proposals are meant to make. In pursuing that clarity, I am attempting to follow through on the comparison of Wittgensteinian and Heideggerian ideas that Dreyfus and his supporters have initiated: what has yet to be clarified is how and why recognizing the 'background' will allow us to 'cope better' with the puzzles in the rule-following literature that they have cited in making a case for the need to recognize the 'background'. Ultimately, I will argue that assessing this matter may require a yet broader comparison of Wittgensteinian and Heideggerian themes, one which raises questions about what we take 'doing ontology' and 'doing phenomenology' to be.

Mon objectif dans cette étude est de montrer l'influence que la philosophie positive d'Auguste Comte a exercée sur la pensée du jeune Brentano durant la période de Würzburg (1866-1874). J'examine d'abord quelques-uns des facteurs qui ont amené Brentano à s'intéresser à la philosophie de Comte et je résume, dans un deuxième temps, les grandes lignes de l'article de Brentano sur Comte dont la version française est reproduite dans ce numéro. Dans la troisième partie de cette étude, je commente brièvement quelques (...) passages de la Psychologie d'un point de vue empirique où Brentano discute de thèmes comtiens. Je conclue cette étude par quelques remarques sur les traces laissées par le positivisme de Comte dans l'œuvre de Brentano. (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)

This paper situates abortion in the context of women’s duties to themselves. I argue that Kant’s fundamental moral requirement to respect oneself as a rational being, combined with Kant’s view of our animal nature, form the basis for a view of pregnancy and abortion that focuses on women’s agency and moral character without diminishing the importance of their bodies and emotions. The Kantian view of abortion that emerges takes abortion to be morally problematic, but sometimes permissible, and sometimes even required. (...) I first sketch Kant’s account to duties to oneself, highlighting duties to oneself as an animal and moral being. Next, I discuss pregnancy and the challenges it poses to women’s self-preservation, development, and efficacy as rational human agents. I then give my main argument: that abortion is morally problematic because it is antagonistic to an important subset of morally useful emotions that we have self-regarding duties to protect and cultivate. I argue that self-regarding moral considerations ground a rebuttable deliberative presumption against maxims of abortion for inclination-based ends. Finally, I consider three objections to this account of abortion : that it rests on implausible assumptions about the effects of abortion on women’s morally useful sentiments; that it portrays the virtuous agent’s reasoning about abortion as objectionably self-regarding; and that it fails adequately to recognize the moral significance of the fetus as a potential rational being.

"Pensées philosophiques" de Denis Diderot. Ecrivain, philosophe et encyclopédiste français (1713-1784).

We build an א₁-categorical but not א₀-categorical theory whose only computably presentable model is the saturated one. As a tool, we introduce a notion related to limitwise monotonic functions.

There has been increasing interest over the last few decades in the study of the effective content of Mathematics. One field whose effective content has been the subject of a large body of work, dating back at least to the early 1960s, is model theory. Several different notions of effectiveness of model-theoretic structures have been investigated. This communication is concerned withcomputablestructures, that is, structures with computable domains whose constants, functions, and relations are uniformly computable.In model theory, we identify isomorphic structures. (...) From the point of view of computable model theory, however, two isomorphic structures might be very different. For example, under the standard ordering of ω the success or relation is computable, but it is not hard to construct a computable linear ordering of type ω in which the successor relation is not computable. In fact, for every computably enumerable degree a, we can construct a computable linear ordering of type ω in which the successor relation has degree a. It is also possible to build two isomorphic computable groups, only one of which has a computable center, or two isomorphic Boolean algebras, only one of which has a computable set of atoms. Thus, for the purposes of computable model theory, studying structures up to isomorphism is not enough. (shrink)

Cet article traite de la question méta-sémantique de ce qui permet au souvenir épisodique d’avoir le contenu sémantique qui est le sien. Il adopte une position singulariste quant au contenu du souvenir et critique la justification méta-sémantique relationnaliste de cette position. Selon celle-ci, le contenu du souvenir est singulier parce que le souvenir consiste en une relation d’accointance avec l’événement passé. L’article oppose un argument causal et un argument sémantique à cette analyse puis montre que les deux traits du souvenir (...) que l’idée d’accointance est censée expliquer – la phénoménologie et la singularité du souvenir – peuvent l’être au moyen de modèles singularistes non fondés sur l’accointance.

Brentano clearly asserts, in his Vienna lectures of 1887–1888, that his descriptive psychology is an a priori or “exact” science. Since he rejects Kant's idea of a synthetic a priori, this means that the descriptive psychologist's laws are analytic. My aim in this paper is to clarify and discuss this view. I examine Brentano's epistemology in the Psychology from an Empirical Standpoint and then its later developments. I conclude with a difficulty inherent in Brentano's psychological approach to a priori knowledge.

The project of articulating a theological ethics on the basis of liturgical anthropology is bound to fail if the necessary consequence is that one has to quit the forum of critical modern rationality. The risk of Engelhardt's approach is to limit rationality to a narrow vision of reason. Sin is not to be understood as the negation of human holiness, but as the negation of divine holiness. The only way to renew theological ethics is to understand sin as the anthropological (...) and ethical expression of the biblical message of the justification by faith only. Sin is therefore a secondary category, which can only by interpreted in light of the positive manifestation of liberation, justification, and grace. The central issue of Christian ethics is not ritual purity or morality, but experience, confession and recognition of our own injustice in our dealing with God and men. (shrink)

We commonly hear it said that a work of art must be understood “on its own terms,” and that phrase is used in other contexts as well; people, especially people very different from ourselves, are said to have to be understood on their own terms. But what is the meaning of the expression “on its/their own terms?” Note that we do not say of every possible object of understanding that it must be understood on its own terms. The statement, “Chemistry (...) must be understood on its own terms,” sounds odd. The “on its own terms” appears to lack point. It invites the retort, “Good grief, on what other terms had you expected to understand it?!” We seem to be brought to this: where the exhortation “understand it on its own terms” is to be used in reference to some object, there must be some reasonable way of understanding that object alternative to understanding it on its own terms. We may ask the child its own childish reasons why it keeps clobbering little sister (“She took my dolly!”), or we may account for its actions in terms the child does not comprehend (“sibling rivalry”). We may on occasion even do the same sort of thing with adults, perhaps giving a reason out of Freud for something done by a person who never heard of Freud or psychoanalysis. But naturally, distinctions between “their terms” and “our terms” become of extreme importance when we attempt to understand the peoples of other cultures. In such cases there literally are different systems of terms, that is, different languages, within which we must make sense of activities. (shrink)

Recently the attempt has been made to demonstrate Heidegger's relevance to the concerns of analytic philosophers. A focus for this effort has been the criticism in his early work of Cartesian ontology. While a number of important works have mapped out this area of Heidegger's thought, a crucial task has not been carried out, namely that of assessing how Heidegger can accommodate those phenomena which motivate the Cartesian to adopt his highly counter-intuitive ontology. As long as we fail to examine (...) how Heidegger's early ontology copes with the possibilities of error and of hallucination, the suspicion will remain that Heidegger is simply insensitive to those phenomena on which the Cartesian focuses. Neither Heidegger nor the Cartesian have been done any favours by commentators showing little inclination to bring the opponents into closer combat. This paper attempts to correct that omission.

Hintikka makes a distinction between two kinds of games: truthconstituting games and truth-seeking games. His well-known game-theoretical semantics for first-order classical logic and its independence-friendly extension belongs to the first class of games. In order to ground Hintikka’s claim that truth-constituting games are genuine verification and falsification games that make explicit the language games underlying the use of logical constants, it would be desirable to establish a substantial link between these two kinds of games. Adapting a result from Thierry Coquand, (...) we propose such a link, based on a slight modification of Hintikka’s games, in which we allow backward playing for ∃loïse. In this new setting, it can be proven that sequent rules for first-order logic, including the cut rule, are admissible, in the sense that for each rule, there exists an algorithm which turns winning strategies for the premisses into a winning strategy for the conclusion. Thus, proofs, as results of truth-seeking games, can be seen. (shrink)

This is the introduction to volume IX of Brentano’s Complete Published Writings: Sämtliche veröffentlichte Schriften: Vermischte Schriften. Brentano’s writings reproduced in this volume provide a substantial complement to important aspects of Brentano's philosophy which are less explicit in the other works he published during his lifetime. This volume contains thirteen writings: three of them belong to the period of Würzburg, two to the Italian period, and the others belong to the period of his teaching in Vienna. They can be grouped (...) under three broad categories. The first corresponds to the theme of the future of philosophy and the philosophical prospects in the late nineteenth century. This issue is recurrent in Brentano's work and is to be found in several of his writings published in this volume, notably in his inaugural address at the University of Vienna, in which he seeks, among other things, to trace the sources of discouragement with respect to the state of philosophy at that time and to rehabilitate confidence and optimism in the future of philosophy. The second topic pertains to Brentano’s philosophy of the history of philosophy and in addition to the article already mentioned in which Brentano elaborates his theory of the four phases, the article „Was für ein Philosoph manchmal Epoche macht“ is an application of the principles of his philosophy of history to Plotinus’ philosophy. The last section entitled Reviews and circumstantial writings contains more circumstantial writings including four reviews, Brentano’s 1908 paper on Thomas von Aquin and a short polemical paper on research without prejudice. It includes „Der Atheismus und die Wissenschaft“ which is an anonymous article in which Brentano criticizes the author of an article published in a Vienna journal on the compatibility of theism with a philosophy that defines itself as science; the second is Brentano’s reply to a critical review of his Psychology by Adolf Horwicz, the third is a review of J. Delitzsch's book on Thomas von Aquinas , and the last is a significant review of a book by Franz Miklosich on the topic of subjektlose Sätze. (shrink)

Whole brain failure constitutes the diagnostic criterion for death determination in most clinical settings across the globe. Yet the conceptual foundation for its adoption was slow to emerge, has evoked extensive scientific debate since inception, underwent policy revision, and remains contentious in praxis even today. Complications result from the need to relate a unitary construal of the death event with an adequate account of organismal integration and that of the human organism in particular. Advances in the neuroscience of higher human (...) faculties, such as the self, personal identity, and consciousness, and dynamical philosophy of science accounts, however, are yielding a portrait of higher order global integration shared between body and brain. Such conceptual models of integration challenge a praxis relying exclusively on a neurological criterion for death. (shrink)

We discuss what makes a “good” environmental nudge from the policy maker’s point of view. We first delineate what is paternalistic about environmental nudges. We then discuss the effectiveness of nudges, including their paradoxical effects on the targeted behaviour, as well as possible collateral effects on the decision-maker’s wellbeing. We also discuss why the libertarian and ethical aspect of nudges may render them more, and not less, attractive as policy instruments and decision aids. We conclude by discussing accuracy and privacy (...) concerns of information-based nudges, and with some recommendations for the design of effective and ethical nudges. (shrink)
