Proper wiring of the nervous system requires tight control of the number of nerve terminals that innervate a target tissue. Recent work by Deppmann et al.,1 now suggests that this is achieved by feedback‐mediated neuronal competition for target‐derived survival cues. The authors' model is inspired by the theory for pattern formation based on self‐activation and lateral inhibition, proposed by Meinhardt and Gierer more than 30 years ago.2 BioEssays 30:929–933, 2008. © 2008 Wiley Periodicals, Inc.

It has often been argued that Humean accounts of natural law cannot account for the role played by laws in scientific explanations. Loewer (Philosophical Studies 2012) has offered a new reply to this argument on behalf of Humean accounts—a reply that distinguishes between grounding (which Loewer portrays as underwriting a kind of metaphysical explanation) and scientific explanation. I will argue that Loewer’s reply fails because it cannot accommodate the relation between metaphysical and scientific explanation. This relation also resolves a puzzle (...) about scientific explanation that Hempel and Oppenheim (Philosophy of Science 15:135–75, 1948) encountered. (shrink)

The goal of this essay is to assess the Selected-Effects Etiological Theory of biological function, according to which a trait has a function F if and only if it has been selected for F. First, I argue that this approach should be understood as describing the paradigm case of functions, rather than as establishing necessary and sufficient conditions for function possession. I contend that, interpreted in this way, the selected-effects approach can explain two central properties of functions and can satisfactorily (...) address some recent counterexamples. This reading, however, shows that there is only a partial overlap between biological functions and selected effects, so the former cannot be reduced to the latter. Finally, I maintain that this result is still compatible with a naturalistic theory of function that appeals to some evolutionary process. (shrink)

The evidence that we get from peer disagreement is especially problematic from a Bayesian point of view since the belief revision caused by a piece of such evidence cannot be modelled along the lines of Bayesian conditionalisation. This paper explains how exactly this problem arises, what features of peer disagreements are responsible for it, and what lessons should be drawn for both the analysis of peer disagreements and Bayesian conditionalisation as a model of evidence acquisition. In particular, it is pointed (...) out that the same characteristic of evidence from disagreement that explains the problems with Bayesian conditionalisation also suggests an interpretation of suspension of belief in terms of imprecise probabilities.

Logical puzzles like the doctrinal paradox raise the problem of how to aggregate individual judgements into a collective judgement, or alternatively, how to merge collectively inconsistent knowledge bases. In this paper, we view judgement aggregation as a function on propositional logic valuations, and we investigate how logic constrains judgement aggregation. In particular, we show that there is no non-dictatorial decision method for aggregating sets of judgements in a logically consistent way if the decision method is local, i.e., only depends on (...) the individual judgements on the proposition under consideration.

Humean accounts of natural lawhood have often been criticized as unable to account for the laws’ characteristic explanatory power in science. Loewer has replied that these criticisms fail to distinguish grounding explanations from scientific explanations. Lange has replied by arguing that grounding explanations and scientific explanations are linked by a transitivity principle, which can be used to argue that Humean accounts of natural law violate the prohibition on self-explanation. Lange’s argument has been sharply criticized by Hicks and van Elswyk, Marshall, (...) and Miller. This paper shows how Lange’s argument can withstand these criticisms once the transitivity principle and the prohibition on self-explanation are properly refined. The transitivity principle should be refined to accommodate contrasts in the explanans and explanandum. The prohibition on self-explanation should be refined so that it precludes a given fact p from helping to explain why some other fact q helps to explain why p. In this way, the transitivity principle avoids having counterintuitive consequences in cases involving macrostates having multiple possible microrealizations. The transitivity principle is perfectly compatible with the irreducibility of macroexplanations to microexplanations and with the diversity of the relations that can underwrite scientific explanations.

As a collective action problem, climate change is best tackled by coordination. Most moral philosophers therefore agree on our individual responsibility as political citizens to help establish such coordination. There is disagreement, however, on our individual responsibilities as consumers to reduce emissions before such coordination is established. In this article I argue that from a Kantian deontological perspective we have a perfect duty to refrain from activities that we would not perform if appropriate coordination were established. Moral autonomy means that (...) we do not need to wait for an external lawmaker to tell us what we ought to do. In practice, this means basing our decisions on a shadow price for carbon: if we would not go out for a drive on a sunny Sunday afternoon in a gas-guzzling sport utility vehicle if gas prices were twice as high, we should not do it now. Moreover, we have imperfect duties to reduce emissions by more than our perfect duties require. (shrink)

The goal of this essay is to put forward an original theory of artifact function, which takes on board the results of the debate on the notion of biological function and also accommodates the distinctive aspects of artifacts. More precisely, the paper develops and defends the Dual-Aspect Theory, which is a monist account according to which an artifact’s function depends on intentional and reproductive aspects. It is argued that this approach meets a set of theoretical and meta-theoretical desiderata and is (...) superior to alternative views. (shrink)

The prevalent views of animal liberty among animal advocates suggest that liberty is merely instrumentally valuable and invasive paternalism is justified. In contrast to this popular view, I argue that liberty is intrinsically good for animals. I suggest that animal well-being is best accommodated by an Objective List Theory and that liberty is an irreducible component of animal well-being. As such, I argue that it is good for animals to possess liberty even if possessing liberty does not contribute towards their (...) subjective well-being, and even in some cases where it has a negative effect upon their subjective well-being. To establish this view I argue that if animals are agents, as I assume they are, then like humans they must be able to determine the course of their own lives (to some extent). Further, having the opportunity to self-determine one’s life just is the very same thing as liberty, and having the opportunity to determine the course of one’s life is intrinsically good. Thus liberty has intrinsic value for humans and animals. So, in addition to the instrumental harms of having one’s liberty restricted, I claim that restricting animals’ liberty in principle harms them because it undermines their capacity for self-determination and fails to acknowledge their authority as agents to make their own choices.

Hempel and Giere contend that the existence of provisos poses grave difficulties for any regularity account of physical law. However, Hempel and Giere rely upon a mistaken conception of the way in which statements acquire their content. By correcting this mistake, I remove the problem Hempel and Giere identify but reveal a different problem that provisos pose for a regularity account — indeed, for any account of physical law according to which the state of affairs described by a law-statement presupposes (...) a Humean regularity. These considerations suggest a normative analysis of law-statements. On this view, law-statements are not distinguished from accidental generalizations by the kind of Humean regularities they describe because a law-statement need not describe any Humean regularity. Rather, a law-statement says that in certain contexts, one ought to regard the assertion of a given type of claim, if made with justification, as a proper way to justify a claim of a certain other kind.

The received view holds that there is a significant divide between full-blown representational states and so called ‘detectors’, which are mechanisms set off by specific stimuli that trigger a particular effect. The main goal of this paper is to defend the idea that many detectors are genuine representations, a view that I call ‘Strong Liberal Representationalism’. More precisely, I argue that ascribing semantic properties to them contributes to an explanation of behavior, guides research in useful ways and can accommodate misrepresentation.

Epistemically immodest agents take their own epistemic standards to be among the most truth-conducive ones available to them. Many philosophers have argued that immodesty is epistemically required of agents, notably because being modest entails a problematic kind of incoherence or self-distrust. In this paper, I argue that modesty is epistemically permitted in some social contexts. I focus on social contexts where agents with limited cognitive capacities cooperate with each other (like juries).

Scientific essentialism aims to account for the natural laws' special capacity to support counterfactuals. I argue that scientific essentialism can do so only by resorting to devices that are just as ad hoc as those that essentialists accuse Humean regularity theories of employing. I conclude by offering an account of the laws' distinctive relation to counterfactuals that portrays laws as contingent but nevertheless distinct from accidents by virtue of possessing a genuine variety of necessity.

I identify the special sort of stability (invariance, resilience, etc.) that distinguishes laws from accidental truths. Although an accident can have a certain invariance under counterfactual suppositions, there is no continuum between laws and accidents here; a law's invariance is different in kind, not in degree, from an accident's. (In particular, a law's range of invariance is not "broader"--at least in the most straightforward sense.) The stability distinctive of the laws is used to explicate what it would mean for there (...) to be multiple grades (or degrees) of physical necessity. Whether there are is for science to discover.

In recent years, there has been an increasing interest on the notion of freedom as non-domination, according to which a subject is free to the extent that no agent has the capacity to arbitrarily interfere on his actions. Now, the most common way of interpreting the notion of freedom as non-domination restricts its applicability to cases where particular agents can intentionally and arbitrarily interfere on a subject�s affairs. In this paper, I present an argument which shows that the standard conception (...) of freedom as non-domination is too restrictive, and that this notion can be extended so as to as to ground a critical point of view on economic and social inequalities.

Können wir als Personen irreversible Gedächtnisverluste überleben? Wie steht es mit Teletransportationen? Wie mit jahrelangem Einfrieren? Fragen wie diese sind weit davon entfernt, bloße Denksportaufgaben für Science-Fiction-Fans zu sein. Vielmehr verraten uns Antworten darauf, welche unserer Eigenschaften uns wirklich wichtig sind und was unser Wesen ausmacht. -/- Unglücklicherweise beantworten Vertreter unterschiedlicher Theorien personaler Identität diese Fragen auf völlig verschiedene Weise. Manche schöpfen die Plausibilität ihrer Positionen aus phantasievollen Gedankenexperimenten; anderen sind dieselben Gedankenexperimente für eine ernsthafte Einbeziehung in die philosophische Theoriebildung (...) schlicht zu wirklichkeitsfern. Es überrascht daher kaum, dass jene Anhänger unterschiedlicher Theorien einander oft wenig zu sagen haben. Im ersten Teil des Buches wird untersucht, unter welchen Umständen Gedankenexperimente aussagekräftige philosophische Werkzeuge sind. Auf der Basis dieser Analyse werden die diversen zeitgenössischen Theorien personaler Identität dann im zweiten Teil einer Neubewertung unterzogen – nicht ohne dass dabei mit vielen selbstverständlich erscheinenden Überzeugungen aufgeräumt wird.

has offered a lovely example to motivate the intuition that a successful prediction has a kind of confirmatory significance that an accommodation lacks. This paper scrutinizes Maher's example. It argues that once the example is tweaked, the intuitive difference there between prediction and accommodation disappears. This suggests that the apparent superiority of prediction to accommodation is actually a side effect of an important difference between the hypotheses that tend to arise in each case.

Sober 2011 argues that, contrary to Hume, some causal statements can be known a priori to be true—notably, some ‘would promote’ statements figuring in causal models of natural selection. We find Sober's argument unconvincing. We regard the Humean thesis as denying that causal explanations contain any a priori knowable statements specifying certain features of events to be causally relevant. We argue that not every ‘would promote’ statement is genuinely causal, and we suggest that Sober has not shown that his examples (...) of ‘would promote’ statements manage to achieve a priori status without sacrificing their causal character.

Our model integrates the nativist assumption of prespecified neural structures underpinning basic emotions with the constructionist view that emotions are assembled from psychological constituents. From a dynamic systems perspective, the nervous system self-organizes in different ways at different time scales, in relation to functions served by emotions. At the evolutionary scale, brain parts and their connections are specified by selective pressures. At the scale of development, connectivity is revised through synaptic shaping. At the scale of real time, temporary networks of (...) synchronized activity mediate responses to situations. To the degree that humans share common emotional functions, neural structuration is similar across scales, giving rise to “basic” emotions. However, unique developmental and situational factors select for neural configurations mediating emotional variants. (shrink)

According to Lange,?Really Statistical explanations? constitute an important kind of non-causalscientific explanation. However, Roski has argued that all alleged RS explanations are either causalexplanations or not explanations at all. In so arguing, Roski has invoked Kahneman?s interpretation of onealleged RS explanation. I employ Roski?s arguments as an opportunity to elaborate and defend RS explanations. Iargue that?RS explanations? genuinely explain rather than deny the presuppositions of why-questions. I argue thatthe RS model is not excessively permissive in allowing some explanations to work (...) purely statistically rather than bydescribing causal relations. I argue that Roski?s view that some?RS explanations? operate by describing causalrelations fails to capture the kind of explanatory insight that RS explanations provide. I elaborate the notion of a?characteristically statistical phenomenon? that figures in the RS model and thereby explain how an RS explanationreveals that its explanandum is independent of any causal facts or specific chances, but rather depends only on ageneric sort of arrangement of chances. Finally, I argue that Roski misinterprets Kahneman, who actually holds thatthe explanation he discusses is a non-causal explanation that nicely fits the RS model. RS explanations constitutean important kind of non-causal scientific explanation. (shrink)

What altered states of consciousness—the dissolution of feelings of time and self—can tell us about the mystery of consciousness. During extraordinary moments of consciousness—shock, meditative states and sudden mystical revelations, out-of-body experiences, or drug intoxication—our senses of time and self are altered; we may even feel time and self dissolving. These experiences have long been ignored by mainstream science, or considered crazy fantasies. Recent research, however, has located the neural underpinnings of these altered states of mind. In this book, neuropsychologist (...) Marc Wittmann shows how experiences that disturb or widen our everyday understanding of the self can help solve the mystery of consciousness. Wittmann explains that the relationship between consciousness of time and consciousness of self is close; in extreme circumstances, the experiences of space and self intensify and weaken together. He considers the emergence of the self in waking life and dreams; how our sense of time is distorted by extreme situations ranging from terror to mystical enlightenment; the experience of the moment; and the loss of time and self in such disorders as depression, schizophrenia, and epilepsy. Dostoyevsky reported godly bliss during epileptic seizures; neurologists are now investigating the phenomenon of the epileptic aura. Wittmann describes new studies of psychedelics that show how the brain builds consciousness of self and time, and discusses pilot programs that use hallucinogens to treat severe depression, anxiety, and addiction. If we want to understand our consciousness, our subjectivity, Wittmann argues, we must not be afraid to break new ground. Studying altered states of consciousness leads us directly to the heart of the matter: time and self, the foundations of consciousness. (shrink)

Marc Jeannerod is director of the Institut des Sciences Cognitives in Lyon. His work in neuropsychology focuses on motor action. The idea that there is an essential relationship between bodily movement, consciousness, and cognition is not a new one, but recent advances in the technologies of brain imaging have provided new and detailed support for understanding this relationship. Experimental studies conducted by Jeannerod and his colleagues at Lyon have explored the details of brain activity, not only as we are (...) actively moving, but as we plan to move, as we imagine moving, and as we observe others move. His work also captures important distinctions between pathological and non-pathological experience. In The Cognitive Neuroscience of Action , Jeannerod focussed on object-oriented actions. What happens in the brain and what do we experience when we reach to grasp an object? How do we plan an action of that sort? To what extent does explicit motor imagery contribute to such action? What role does a motor representation or motor schema play in the accomplishment of action? At the very end of that book he raises questions that seem quite different. How is it possible to understand the intentions of others? Precisely what mechanisms allow us to imitate other people's actions? In more recent years much of Jeannerod's work has been in pursuit of these questions about interaction with others, and he has helped to show that there are intimate connections between moving ourselves and understanding others. Jeannerod's work does not lack important implications for a philosophical understanding of human activity. Although in contemporary philosophical debates on consciousness one can still find arguments that simply ignore bodily movement as an important factor in cognition, several recent works have returned to serious consideration of movement and action . In the following interview Jeannerod discusses many issues relevant to the philosophy of mind and action, including concepts of intentionality, movement and consciousness of movement, the role of simulation in understanding others, and the best way to conceptualize brain processes in all of these regards. Importantly, he makes constant reference to the empirical evidence, much of it developed in his own experimental studies. (shrink)

Ethics education in the professions has become close to compulsory with continuing education following suit. What is the de facto as opposed to the de jure function of an ethics education program? Have they increased compliance with laws and codes of conduct? Is that the goal? What would an ethics education program look like that was not primarily concerned with compliance with relevant laws or professional codes and not merely an exercise in good public relations? I argue that, ultimately, ethics (...) education is about happiness… not happiness as we generally think of it today, but in the Aristotelian sense of “fulfillment” and the collateral good that is generated for clients and the profession. As a result of this point of view I argue that ethics is not a subject in the normal sense of the term but a meta-subject which implies that teaching ethics as a class or stand alone module in a law, policy or practice management course is usually ineffective. Another implication is that the richest source for moral reflection within a profession are case studies generated by students in clinical assignments, despite the inherent risks associated with making these cases prominent.

This paper argues that social trust is the emergent product of a complex system of property relations, backed up by a sub-system of mutual monitoring. This happens in a context similar to Ostrom’s commons, where cooperation is necessary for the management of resources, in the absence of external authorities to enforce sanctions. I show that social trust emerges in this context because of an institutional structure that enables individuals to develop a generalized disposition to internalize the external effects of their (...) actions. This is made possible by the “patrimonial” nature of this structure. (shrink)

Why should science be so interested in discovering whether p is a law over and above whether p is true? The answer may involve the laws' relation to counterfactuals: p is a law iff p would still have obtained under any counterfactual supposition that is consistent with the laws. But unless we already understand why science is especially concerned with the laws, we cannot explain why science is especially interested in what would have happened under those counterfactual suppositions consistent with (...) the laws. It is argued that the laws form the only non-trivially "stable" set, where "stability" is invariance under a certain range of counterfactual suppositions not itself defined by reference to the laws. It is then explained why science should be so interested in identifying a non-trivially "stable" set: because of stability's relation to the best set of "inductive strategies". (shrink)

This paper concerns the relation between a proof’s beauty and its explanatory power – that is, its capacity to go beyond proving a given theorem to explaining why that theorem holds. Explanatory power and beauty are among the many virtues that mathematicians value and seek in various proofs, and it is important to come to a better understanding of the relations among these virtues. Mathematical practice has long recognized that certain proofs but not others have explanatory power, and this paper (...) offers an account of what makes a proof explanatory. This account is motivated by a wide range of examples drawn from mathematical practice, and the account proposed here is compared to other accounts in the literature. The concept of a proof that explains is closely intertwined with other important concepts, such as a brute force proof, a mathematical coincidence, unification in mathematics, and natural properties. Ultimately, this paper concludes that the features of a proof that would contribute to its explanatory power would also contribute to its beauty, but that these two virtues are not the same; a beautiful proof need not be explanatory.

This is the first appearance in English translation (and the first appearance anywhere since a now-hard-to-find 1939 Turkish publication) of Reichenbach’s popular lecture “The Problem of Laws of Nature.” In his lecture, Reichenbach deftly carries his audience through a vast array of interrelated topics concerning probability, natural law, determinism, statistical mechanics, quantum mechanics, fate, explanation, the justification of induction, and the scientist as wagerer. A brief commentary situating the lecture in a broader historical and philosophical context is provided. The translation (...) aims to convey Reichenbach’s own voice, which is by turns serious, playful, ironic, admonitory and inspirational. (shrink)

Jean-Marc Coicaud's article begins by stressing the contemporary importance and the current trend of political apology. Recent political apologies offered in Australia and Canada to their indigenous populations form a significant part of this story. He then analyzes a number of intriguing paradoxes at the core of the dynamics of apology. These paradoxes give meaning to apology but also make the very idea of apology extremely challenging. They have to do with the relationships of apology with time, law and (...) the unforgivable. The most intriguing of these paradoxes concerns apology and the unforgivable. Indeed, the greater the wrong, the more valuable the apology. But, then, the more difficult it becomes to issue and to accept an apology. This latter paradox is namely examined in the context of mass crimes, taken from Europe, Africa and Asia. As a whole these paradoxes are all the more intriguing considering what apology in a political context aims to accomplish, for the actor who issues the apology, for the one who receives it, for their relationship, and for the social environment in which this takes place. Jean-Marc Coicaud concludes his article by outlining what the rise of apology means for contemporary political culture. (shrink)

Part of teaching the descriptive phenomenological psychological method is to assist students in grasping their previously unrecognized assumptions regarding the meaning of “science.” This paper is intended to address a variety of assumptions that are encountered when introducing students to the descriptive phenomenological psychological method pioneered by Giorgi. These assumptions are: 1) That the meaning of “science” is exhausted by empirical science, and therefore qualitative research, even if termed “human science,” is more akin to literature or art than methodical, scientific (...) inquiry; 2) That as a primarily aesthetic, poetic enterprise human scientific psychology need not attempt to achieve a degree of rigor and epistemological clarity analogous to that pursued by natural scientists; 3) That “objectivity” is a concept belonging to natural science, and therefore human science ought not to strive for objectivity because this would require “objectivizing” the human being; 4) That qualitative research must always adopt an “interpretive” approach, description being seen as merely a mode of interpretation. These assumptions are responded to from a perspective drawing primarily upon Husserl and Merleau-Ponty, but also upon Eagleton’s analysis of aestheticism. (shrink)

In a recent article in this journal, Remsen attacked moral objections to killing birds for museum collections, objections that are frequently raised by the general public and scientific community alike. The only grounds for moral objections against killing birds that Remsen considers and rejects are reverence for all life or personal, that is sentimental reasons. What Remsen ignores is avian sentience and the moral imperative of respecting it.

Although the topic has been extensively studied, many issues about understanding of indirect requests in children are still unsolved. Our contribution is to distinguish genuine and ironic hints, focusing on the latter. We examined the understanding of ironic hints and ironic imperatives in 5- to 9-year-old children and in adults, in various situational contexts. The main result of this study was that ironic hints were more difficult to understand than ironic imperatives only when the context was neutral. When the context (...) was ironic, there was no significant difference. Discussion highlights how context enables young children to understand very indirect requests like ironic hints. (shrink)
