In Emotions, Values & Agency, Christine Tappolet develops a sophisticated, perceptual theory of emotions and their role in wide range of issues in value theory and epistemology. In this paper, we raise three worries about Tappolet's proposal.

I distinguish between two kinds of selection effects on experience: selection of objects or features for experience, and anti-selection of experiences for cognitive uptake. I discuss the idea that both kinds of selection effects can lead to a form of confirmation bias at the level of perception, and argue that when this happens, selection effects can influence the rational role of experience.

Natural selection is a general process that operates in different populations. To characterise natural selection as a mechanism within the framework of the new mechanistic philosophy, it is required to identify a pertinent phenomenon for which natural selection is responsible. Firstly, every case identified by evolutionary biologists as instances of natural selection must align with this mechanistic characterisation. Secondly, natural selection should genuinely be responsible for the attributed phenomenon. While philosophers often posit producing adaptation as the quintessential phenomenon, Pérez-González and (...) Luque challenge this perspective, contending that not all instances of natural selection are cases where natural selection produces adaptation. This paper further supports Pérez-González and Luque’s objection and demonstrates that natural selection is also not responsible for the increased frequency of traits with a greater expected number of offspring. Furthermore, the paper argues that even if there is a phenomenon that allows for the mechanistic characterisation of natural selection to encompass all instances, it is improbable that natural selection assumes responsibility for it. Consequently, characterising natural selection as a mechanism emerges as an implausible stance. (shrink)

This paper argues that, if we are committed to a Pro-choice stance with regard to selective abortion for disability, we will be unable to justify the prohibition of sex-selective abortion (SSA), for two reasons. First, familiar Pro-choice arguments in favour of a woman’s right to select against fetal impairment also support, by parity of reasoning, a right to choose SSA. Second, rejection of the criticisms of selective abortion for disability levelled by disability theorists also disposes, by implication, of the key (...) objections to SSA, as developed, most notably, by feminists. The paper, then, consists of a conditional defence of SSA, under which SSA should be available, and protected by a right, if selective abortion for disability is. Opponents of SSA might respond by conceding additional restrictions on selection against disabled fetuses. It should become clear throughout the paper, however, that any such new restrictions would be unacceptably onerous for women. (shrink)

Machine‐learning algorithms have the potential to revolutionise diagnostic and prognostic tasks in health care, yet algorithmic performance levels can be materially worse for subgroups that have been underrepresented in algorithmic training data. Given this epistemic deficit, the inclusion of underrepresented groups in algorithmic processes can result in harm. Yet delaying the deployment of algorithmic systems until more equitable results can be achieved would avoidably and foreseeably lead to a significant number of unnecessary deaths in well‐represented populations. Faced with this dilemma (...) between equity and utility, we draw on two case studies involving breast cancer and melanoma to argue for the selective deployment of diagnostic and prognostic tools for some well‐represented groups, even if this results in the temporary exclusion of underrepresented patients from algorithmic approaches. We argue that this approach is justifiable when the inclusion of underrepresented patients would cause them to be harmed. While the context of historic injustice poses a considerable challenge for the ethical acceptability of selective algorithmic deployment strategies, we argue that, at least for the case studies addressed in this article, the issue of historic injustice is better addressed through nonalgorithmic measures, including being transparent with patients about the nature of the current epistemic deficits, providing additional services to algorithmically excluded populations, and through urgent commitments to gather additional algorithmic training data from excluded populations, paving the way for universal algorithmic deployment that is accurate for all patient groups. These commitments should be supported by regulation and, where necessary, government funding to ensure that any delays for excluded groups are kept to the minimum. We offer an ethical algorithm for algorithms—showing when to ethically delay, expedite, or selectively deploy algorithmic systems in healthcare settings. (shrink)

It is often claimed that our knowledge of the evolutionary process adds an extra dimension to the classical problem of natural evil and makes this problem worse. Especially the principle of natural selection is often portrayed as morally inappropriate or “unfitting” for a perfectly good God to use as a means for creating biological complexity. In this article, I argue that this common view is misconceived, and that natural selection is a wholly innocuous principle. The real source of evolutionary evils (...) is the fact that resources in nature are scarce – a fact that was known long before Darwin. The problem of natural and evolutionary evil, therefore, is best construed as a question about why God permits scarcity in nature. I argue that recent research about the interrelation between competition and cooperation in the evolutionary process provides resources for answering this perennial question in a more satisfactory way than could be done before the advent of evolutionary theory.

Eva Picardi has been one of the most influential Italian analytic philosophers of her generation. She taught for forty years at the University of Bologna, raising three generations of students. This collection of selected writings honors her work, confirming Picardi's status as one of the most important Frege scholars of her generation and a leading authority on the philosophy of Donald Davidson. Bringing together Picardi's contributions to the history of analytic philosophy, it includes her papers on major 20th-century figures such (...) as Wittgenstein, Quine, Davidson, Rorty, and Brandom. She examines their work in comparison with the philosopher Michael Dummett's, illuminating contrasts between American Neo-pragmatism and Continental philosophy. By considering key contributions made by Gadamer and Adorno and contrasting them with Davidson and Rorty's proposals, Picardi is able to bridge the Analytic and Continental divide. Featuring an introduction by Annalisa Coliva and new translations of previously unpublished papers, this collection emphasizes the significance of Picardi's work for a new generation of readers.

Natural selection is an important force that shapes the evolution of all living things by determining which individuals contribute the most descendents to future generations. The biological unit upon which selection acts has been the subject of serious debate, with reasonable arguments made on behalf of populations, individuals, individual phenotypic characters and, finally, individual genes themselves. In this essay, I argue that the usual unit of selection is the gene. There are powerful logical arguments in favor of this conclusion, as (...) well as many real-world examples. I also explore the possibility that epigenetic differences between individuals may be heritable between generations. Although few such examples exist, epigenetic differences provide an exciting source of potentially heritable variation that may allow rapid evolutionary change to occur, perhaps in response to environmental influences.

.... The strategy I have defended involves drawing a distinction between those who can and cannot legitimately hold an agent responsible in circumstances when the agent is being covertly controlled (e.g. through implantation processes). What is intuitively unacceptable, I maintain, is that an agent should be held responsible or subject to reactive attitudes that come from another agent who is covertly controlling or manipulating him. This places some limits on who is entitled to take up the participant stance in relation (...) to agents who are rational self-controllers but nevertheless subject to covert control.26 In this way, what is compromised by conditions of covert control is not the responsibility of the agent as such. It is, rather, the participant stance of those other agents who covertly control him. Clearly it is possible to establish these specific limits on who can hold these agents responsible without denying that the agents themselves remain free and responsible. When we take this approach we will find that we are no longer faced with an unattractive choice between simply “biting the bullet” or having to “spit it out”. All we need to do is chew carefully, until there is nothing left that we find too hard to swallow. (shrink)

In The Biopsychosocial Model of Health and Disease, Derek Bolton and Grant Gillett argue that a defensible updated version of the biopsychosocial model requires a metaphysically adequate account of disease causation that can accommodate biological, psychological, and social factors. This present paper offers a philosophical critique of their account of biopsychosocial causation. I argue that their account relies on claims about the normativity and the semantic content of biological information that are metaphysically contentious. Moreover, I suggest that these claims are (...) unnecessary for a defence of biopsychosocial causation, as the roles of multiple and diverse factors in disease causation can be readily accommodated by a more widely accepted and less metaphysically contentious account of causation. I then raise the more general concern that they are misdiagnosing the problem with the traditional version of the biopsychosocial model. The challenge when developing an explanatorily valuable version of the biopsychosocial model, I argue, is not so much providing an adequate account of biopsychosocial causation, but providing an adequate account of causal selection. Finally, I consider how this problem may be solved to arrive at a more explanatorily valuable and clinically useful version of the biopsychosocial model. (shrink)

According to the scenario of cosmological artificial selection and artificial cosmogenesis, our universe was created and possibly even fine-tuned by cosmic engineers in another universe. This approach shall be compared to other explanations, and some far-reaching problems of it shall be discussed.

Does natural selection act primarily on individual organisms, on groups, on genes, or on whole species? The question of levels of selection - on which biologists and philosophers have long disagreed - is central to evolutionary theory and to the philosophy of biology. Samir Okasha's comprehensive analysis gives a clear account of the philosophical issues at stake in the current debate.

According to scientific realists, the predictive success of mature theories provides a strong epistemic basis for thinking that such theories are approximately true. However, we know that many theories once regarded as well-confirmed and predictively successful were eventually replaced with successor theories, and some claim this undermines the epistemic confidence we should have in the approximate truth of current science. Selective scientific realists in turn argue that if one can show that the predictive success of some rejected theory T is (...) a function of theoretical claims consistent with current science, then T’s failure doesn’t undermine the claim that current successful theories are approximately true. As such, Selective Scientific Realism (SSR) can be tested through historical examples. Showing that the predictive success of a failed theory is the result of theoretical features later rejected provides a counterexample to SSR. Conversely, SSR is supported if its explanation of the predictive success of failed theories--namely, that the factors which lead to predictive success in the failed theory survive in the successor theory--is able to handle a wide array of historical cases.

Humans have a much longer juvenile period (weaning to first reproduction, 14 or more years) than their closest relatives (chimpanzees, 8 years). Three explanations are prominent in the literature. (a) Humans need the extra time to learn their complex subsistence techniques. (b) Among mammals, since length of the juvenile period bears a constant relationship to adult lifespan, the human juvenile period is just as expected. We therefore only need to explain the elongated adult lifespan, which can be explained by the (...) opportunity for older individuals to increase their fitness by providing for grandchildren. (c) The recent model by Kaplan and colleagues suggests that longevity and investment in "embodied capital" will coevolve, and that the need to learn subsistence technology contributed to selection for our extended lifespan.We report experiments designed to test the first explanation: human subsistence technology takes many years to learn, and spending more time learning it gives reproductive benefits that outweight lost time. Taking away some of this time should lead to deficits in efficiency. We paid Hadza foragers to participate in tests of important subsistence skills. We compared efficiency of males and females at digging tubers. They differ greatly in time spent practicing digging but show no difference in efficiency. Children who lost "bush experience" by spending years in boarding school performed no worse at digging tubers or target archery than those who had spent their entire lives in the bush. Climbing baobab trees, an important and dangerous skill, showed no change with age among those who attempted it. We could show no effects of practice time.These findings do not support what we label "the practice theory," but we discuss ways in which the theory could be defended; for example, some as-yet-untested skill may be greatly impaired by loss of a few years of the juvenile period. Our data also show that it is not safe to assume that increases in skill with age are entirely due to learning or practice; they may instead be due to increases in size and strength. (shrink)

Excerpt from Selections From Pascal Blaise pascal was born at Clermont - Ferrand, in the center of F rance, on June 19, 1623. Three years later his mother died, and his father, taking the family duties most seriously, decided to be his son's own educator. At this time the father occupied a judicial position of considerable importance, but in 1630 he retired from it, moved the household to Paris, and gave himself up entirely to his work of preceptor. He (...) taught Blaise Latin and Greek, Mathematics and Physics, Logic and Philoso phy. For scientific studies the; boy showed unusual aptitude. At the age of twelve he was so far advanced as to write an essay on acoustics, which was followed at fifteen by treatise on conic sections. At eighteen he invented machine for count ing numbers. So great was his zeal for learning that he over taxed his strength by too steady application. Disorders ap peared, headaches and neuralgia, and his sister, Mme Perier, is authority for the statement that, from this time on, he rarely passed day without pain.

Two topics, Science and History, have been studied for centuries, if not millennia, often in disjointed ways. The realization that Science is nourished by its History is quite obvious nowadays and is a standpoint shared by all the contributors in this book. Given this fact, the following chapters were written by interdisciplinary scholars who are experts in this field. The admirably written contributions concern History of Science, Epistemology, Philosophy of Science, but are not restricted to these disciplines. They also discuss (...) theoretical perspectives and ingenious results achieved by beautiful and clever minds working together or inspired by one another. Torricelli’s history is a fascinating one, filled with struggles and insights that have been studied and examined in depth by internationally renowned specialists. The gripping stories reconstructed, as well as the epistemological and logical threads drawn from long and painstaking research, are presented in a clear and absorbing fashion, in each instance with a unique style and always with considerably talented analysis. The preceding celebratory historical and historiographical chapter on Opera geometrica (Torricelli in Opera geometrica. Florentiae. Masse & de Landis (1644); Torricelli in Opere di Evangelista Torricelli edite in occasione del III centenario della nascita col concorso del Comune di Faenza da Gino Loria e Giuseppe Vassura. Montanari (1919–1944)) is also a structured introductory essay to the contents of this extensive Springer research project. Below, the reader will find summaries of selected distinguished essays written in order to celebrate the magnificence of Torricelli’s Opera geometrica. The whole volume has to be considered as an homage both to Opera geometrica and to Evangelista, a genial scientist. (shrink)

The chapter explores whether, or to what extent, recent work in experimental philosophy puts pressure on the idea that the concept of causation is ‘egalitarian’. Causal selection – where experimental subjects tend to rate the causal strength of (for example) a norm-violator more strongly than a non-norm-violator – is a well established phenomenon, and is in prima facie tension with an egalitarian conception of causation; it also, indirectly, puts prima facie pressure on the idea that causation is a worldly phenomenon (...) whose obtaining is independent of facts about norms. The chapter explores both the various psychological mechanisms and the broadly pragmatic approaches to explaining causal selection. It argues that the answer to the question whether or not the concept of causation is egalitarian is currently significantly empirically underdetermined, and suggests some avenues for further investigation.

We have argued elsewhere that: (A) Natural selection is not a cause of evolution. (B) A resolution-of-forces (or vector addition) model does not provide us with a proper understanding of how natural selection combines with other evolutionary influences. These propositions have come in for criticism recently, and here we clarify and defend them. We do so within the broad framework of our own “hierarchical realization model” of how evolutionary influences combine.

Mainstream teleosemantics is the view that mental representation should be understood in terms of biological functions, which, in turn, should be understood in terms of selection processes. One of the traditional criticisms of teleosemantics is the problem of novel contents: how can teleosemantics explain our ability to represent properties that are evolutionarily novel? In response, some have argued that by generalizing the notion of a selection process to include phenomena such as operant conditioning, and the neural selection that underlies it, (...) we can resolve this problem. Here, we do four things: we develop this suggestion in a rigorous way through a simple example, we draw on recent neurobiological research to support its empirical plausibility, we defend the move from a host of objections in the literature, and we sketch how the picture can be extended to help us think about more complex “conceptual” representations and not just perceptual ones.

Selective permeability holds that people’s distinct capacities allow them to do different things in a space, making it unequally accessible. Though mainly applied to urban geography so far, we propose selective permeability as an affordance-based approach for understanding diversity in education. This has advantages. First, it avoids dismissing lower achievements as necessarily coming from “within” students, instead locating challenges in the environment. This implies that settings (not just people) need remedial attention, also raising questions about normative judgments in disability nomenclature. (...) Second, affordances can be negotiated in numerous ways to reach a goal, analogously to how people with missing arms have learned to drive with their feet, so restrictive problem-solving methods are often counterproductive. Third, our approach illuminates how cultural factors ranging from gait styles to language and hence group coordination modulate action possibilities, so that cultural groups may encounter objectively different affordances in the same classroom. But fourth, while fit with environment allows for skill refinement, non-fit can contribute to growth situations, which suggests a degree of selective closure can be desirable. Throughout, we argue social constructs—including educational ones—are literally built or enacted barriers or openings that have reality in environments in the same way that affordances do. (shrink)

Human behavior is the joint product of (i) contingencies of survival responsible for natural selection, and (ii) contingencies of reinforcement responsible for the repertoires of individuals, including (iii) the special contingencies maintained by an evolved social environment. Selection by consequences is a causal mode found only in living things, or in machines made by living things. It was first recognized in natural selection: Reproduction, a first consequence, led to the evolution of cells, organs, and organisms reproducing themselves under increasingly diverse (...) conditions. The behavior functioned well, however, only under conditions similar to those under which it was selected.Reproduction under a wider range of consequences became possible with the evolution of processes through which organisms acquired behavior appropriate to novel environments. One of these, operant conditioning, is a second kind of selection by consequences: New responses could be strengthened by events which followed them. When the selecting consequences are the same, operant conditioning and natural selection work together redundantly. But because a species which quickly acquires behavior appropriate to an environment has less need for an innate repertoire, operant conditioning could replace as well as supplement the natural selection of behavior.Social behavior is within easy range of natural selection, because other members are one of the most stable features of the environment of a species. The human species presumably became more social when its vocal musculature came under operant control. Verbal behavior greatly increased the importance of a third kind of selection by consequences, the evolution of social environments or cultures. The effect on the group, and not the reinforcing consequences for individual members, is responsible for the evolution of culture. (shrink)

Many people have argued that the evolution of the human language faculty cannot be explained by Darwinian natural selection. Chomsky and Gould have suggested that language may have evolved as the by-product of selection for other abilities or as a consequence of as-yet unknown laws of growth and form. Others have argued that a biological specialization for grammar is incompatible with every tenet of Darwinian theory – that it shows no genetic variation, could not exist in any intermediate forms, confers (...) no selective advantage, and would require more evolutionary time and genomic space than is available. We examine these arguments and show that they depend on inaccurate assumptions about biology or language or both. Evolutionary theory offers clear criteria for when a trait should be attributed to natural selection: complex design for some function, and the absence of alternative processes capable of explaining such complexity. Human language meets these criteria: Grammar is a complex mechanism tailored to the transmission of propositional structures through a serial interface. Autonomous and arbitrary grammatical phenomena have been offered as counterexamples to the position that language is an adaptation, but this reasoning is unsound: Communication protocols depend on arbitrary conventions that are adaptive as long as they are shared. Consequently, language acquisition in the child should systematically differ from language evolution in the species, and attempts to analogize them are misleading. Reviewing other arguments and data, we conclude that there is every reason to believe that a specialization for grammar evolved by a conventional neo-Darwinian process. (shrink)

This paper argues that the HFEA’s recent report on sex selection abdicates its responsibility to give its own authentic advice on the matters within its remit, that it accepts arguments and conclusions that are implausible on the face of it and where they depend on empirical claims, produces no empirical evidence whatsoever, but relies on reckless speculation as to what the “facts” are likely to be. Finally, having committed itself to what I call the “democratic presumption”, that human freedom will (...) not be constrained unless very good and powerful reasons can be produced to justify such infringement of liberty, the HFEA simply reformulates the democratic presumption as saying the opposite—namely that freedom may only be exercised if powerful justifications are produced for any exercise of liberty.

A common misunderstanding of the selected effects theory of function is that natural selection operating over an evolutionary time scale is the only functionbestowing process in the natural world. This construal of the selected effects theory conflicts with the existence and ubiquity of neurobiological functions that are evolutionary novel, such as structures underlying reading ability. This conflict has suggested to some that, while the selected effects theory may be relevant to some areas of evolutionary biology, its relevance to neuroscience is (...) marginal. This line of reasoning, however, neglects the fact that synapses, entire neurons, and potentially groups of neurons can undergo a type of selection analogous to natural selection operating over an evolutionary time scale. In the following, I argue that neural selection should be construed, by the selected effect theorist, as a distinct type of function-bestowing process in addition to natural selection. After explicating a generalized selected effects theory of function and distinguishing it from similar attempts to extend the selected effects theory, I do four things. First, I show how it allows one to identify neural selection as a distinct function-bestowing process, in contrast to other forms of neural structure formation such as neural construction. Second, I defend the view from one major criticism, and in so doing I clarify the content of the view. Third, I examine drug addiction to show the potential relevance of neural selection to neuroscientific and psychological research. Finally, I endorse a modest pluralism of function concepts within biology. (shrink)

Various results show the ‘formal equivalence’ of kin and group selectionist methodologies, but this does not preclude there being a real and useful distinction between kin and group selection processes. I distinguish individual- and population-centred approaches to drawing such a distinction, and I proceed to develop the latter. On the account I advance, the differences between kin and group selection are differences of degree in the structural properties of populations. A spatial metaphor provides a useful framework for thinking about these (...) differences: kin and group selection may be conceptualized as large, overlapping regions of K - G space. I then consider some implications of the account, defend it from possible objections, and further argue that the structural features characteristic of both kin and group selection may recur at multiple levels of biological organization.

The notion that natural selection is a process of fitness maximization gets a bad press in population genetics, yet in other areas of biology the view that organisms behave as if attempting to maximize their fitness remains widespread. Here I critically appraise the prospects for reconciliation. I first distinguish four varieties of fitness maximization. I then examine two recent developments that may appear to vindicate at least one of these varieties. The first is the ‘new’ interpretation of Fisher's fundamental theorem (...) of natural selection, on which the theorem is exactly true for any evolving population that satisfies some minimal assumptions. The second is the Formal Darwinism project, which forges links between gene frequency change and optimal strategy choice. In both cases, I argue that the results fail to establish a biologically significant maximization principle. I conclude that it may be a mistake to look for universal maximization principles justified by theory alone. A more promising approach may be to find maximization principles that apply conditionally and to show that the conditions were satisfied in the evolution of particular traits. (shrink)
