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)

Marya Schechtman and Grant Gillett acknowledge that my case in ‘The misunderstandings of the Self-Understanding View’ (2013) has some merits, but neither is moved to change their position and accept that the Psychological View has more going for it (and the Self-Understanding View less) than Schechtman originally contended. Schechtman thinks her case could be better expressed, and then the deficiencies of the Psychological View will be manifest. That view is committed to Locke’s insight about the importance of phenomenological (...) connections to identity, but cannot do justice to this insight and as a result fails to explain things that it should. I will argue that my case still applies, re-expression notwithstanding .. (shrink)

Addressing concerns about the treatment of psychopaths, Grant Gillett and Flora Huang (2013) argue that we ought to accept a relational or holistic view of psychopathy and APSD rather than the default biomedical-deficit model since the latter “obscures moral truths about the psychopath”. This change in approach to the psychopath will both mitigate at least some of their moral responsibility for the harms they cause, and force communities to incur special obligations, so they claim, because the harms endured (...) by psychopaths will be understood as part of the cause for the harms they are guilty of committing. However, as I will argue, even if we accept that a relational or holistic approach is better suited to understand psychopathy (which is itself contentious), it does not follow that their responsibility is mitigated in a way that causes communities to have special obligations to them as Gillett and Huang suggest. A diagnosis of APSD or psychopathy does not, prima facie, exculpate an agent or suggest a different way of treating them. My discussion will focus on the widely accepted excusing conditions one must meet for responsibility to me mitigated and conclude, contra Gillett and Huang, that psychopaths are no different from you or I with regards to having a causal history that leads to action. Outside forces play a role in all of our behavior. If the psychopath is owed anything because of the way they have come to understand the world then we all are owed that same debt. (shrink)

In this paper, we analyse how GPS-based navigation systems are transforming some of our intellectual virtues and then suggest two strategies to improve our practices regarding the use of such epistemic tools. We start by outlining the two main approaches in virtue epistemology, namely virtue reliabilism and virtue responsibilism. We then discuss how navigation systems can undermine five epistemic virtues, namely memory, perception, attention, intellectual autonomy, and intellectual carefulness. We end by considering two possible interlinked ways of trying to remedy (...) this situation: [i] redesigning the epistemic tool to improve the epistemic virtues of memory, perception, and attention; and [ii] the cultivation of cognitive diligence for wayfinding tasks scaffolding intellectual autonomy and carefulness.

Abstract: There has recently been controversy over the existence of 'multiple realization' in addition to some confusion between different conceptions of its nature. To resolve these problems, we focus on concrete examples from the sciences to provide precise accounts of the scientific concepts of 'realization' and 'multiple realization' that have played key roles in recent debates in the philosophy of science and philosophy of psychology. We illustrate the advantages of our view over a prominent rival account ( Shapiro, 2000 and (...) 2004 ) and use our work to rebut recent objections to the long-standing claim that psychological properties are multiply realized. For we use scientific evidence, in combination with our more precise theoretical framework, to show that we have strong reason to believe that psychological properties are indeed multiply realized both at the biochemical and neuronal levels.

This essay explores the intersection of racism, racial embodiment theory and the recent hostility aimed at immigrants and foreigners in the United States, especially the targeting of people of Latin American descent and Latino/as. Anti-immigrant and anti-foreigner sentiment is racist. It is the embodiment of racial privilege for those who wield it and the materiality of racial difference for those it is used against. This manifestation of racial privilege and difference rests upon a redrawing of the color line that is (...) meant towards preserving exclusive categories of political membership. The charge of racism, however, is elided by the fact that this hostility takes the form of a specious embracement of law and lawfulness. “Illegal” in this sense not only captures the actions of those who enter the United States through clandestine or informal means, but, in light of the history of immigration and citizen- ship law, the term operates as a racial trope that designates non-white status, thus marginalizing and alienating certain immigrants from ongoing nation-formation processes. I explain the source for anti-immigrant hostility in the United States, which I take to be connected to the longevity of white normativity as the basis for American identity. I then critically assess how the idea of national belonging is crucial to the perpetuation of white-ways-of-being, especially when citizenship has historically been a venue for the embodiment of racial and even colonial privilege. I conclude by posing several questions about the nature of racial identities and racism that suggest new avenues for further research on racial embodiment in a “postracial” era. pp. 65–90. (shrink)

Biologists seems to hold two fundamental beliefs: Organisms are organized into levels and the individuals at these levels differ in their properties. Together these suggest that there will be massive multiple realization, i.e. that many human psychological properties are multiply realized at many neurobiological levels. This paper provides some documentation in support of this suggestion.

The aim of this paper is to explain why creativity is an artistic merit. Artworks and non-artworks can both be creative. But creativity does not help make many other creative things good of their kind. A creative explanation is not a better explanation in virtue of being creative. Why, then, is a creative artwork a better artwork in virtue of being creative? Understanding this will give us a better understanding of the nature of artistic merit. The approach adopted in this (...) paper is as follows. First, I say what creativity is and what an artistic merit is. Second, I identify reasons to doubt that creativity is an artistic merit. A good explanation of the merit of creativity should address these doubts. Third, I develop a theory of artistic merit that appeals to the final value of acting excellently – for example, virtuously or skilfully. Finally, I argue that this enables us to explain why creativity is an artistic merit. This account also enables us to argue that artistic merits give some things final value, and not merely instrumental value. It also provides reason to believe that ethical qualities of artworks enhance their artistic merit for the same reason creativity does. (shrink)

This essay is about the loss of voice. It is about the ways in which the act of writing philosophy often results in an alienating and existentially meaningless experience for many budding philosophers, particularly those who wish to think from their racialized and gendered identities in professional academic philosophy.

A critical review essay, this work explains the methodological, material, and ideological reasons for why "diversity" initiatives in philosophy face an up-hill battle.

Human nature is frequently evoked to characterize our species and describe how it differs from others. But how should we understand this concept? What is the nature of a species? Some take our nature to be an essence and argue that because humans lack an essence, they also lack a nature. Others argue for non-essentialist ways of understanding human nature, which usually aim to provide criteria for sorting human traits into one of two bins, the one belonging to our nature (...) and the other outside our nature. This Element argues that both the essentialist and trait bin approaches are misguided. Instead, the author develops a trait cluster account of human nature, which holds that human nature is based on the distribution of our traits over our (actual and possible) life histories. One benefit of this account is that it aligns human nature with the human sciences, rendering the central concern of the human sciences to be the study of human nature. (shrink)

The ongoing explosion of interest in artificial intelligence is fueled in part by recently developed techniques in machine learning. Those techniques allow automated systems to process huge amounts of data, utilizing mathematical methods that depart from traditional statistical approaches, and resulting in impressive advancements in our ability to make predictions and uncover correlations across a host of interesting domains. But as is now widely discussed, the way that those systems arrive at their outputs is often opaque, even to the experts (...) who design and deploy them. Is it morally problematic to make use of opaque automated methods when making high-stakes decisions, like whether to issue a loan to an applicant, or whether to approve a parole request? Many scholars answer in the affirmative. However, there is no widely accepted explanation for why transparent systems are morally preferable to opaque systems. We argue that the use of automated decision-making systems sometimes violates duties of consideration that are owed by decision-makers to decision-subjects, duties that are both epistemic and practical in character. Violations of that kind generate a weighty consideration against the use of opaque decision systems. In the course of defending our approach, we show that it is able to address three major challenges sometimes leveled against attempts to defend the moral import of transparency in automated decision-making.

An increasing number of writers (for example, Kim ((1992), (1999)), Bechtel and Mundale (1999), Keeley (2000), Bickle (2003), Polger (2004), and Shapiro ((2000), (2004))) have attacked the existence of multiple realization and wider views of the special sciences built upon it. We examine the two most important arguments against multiple realization and show that neither is successful. Furthermore, we also defend an alternative, positive view of the ontology, and methodology, of the special science. In contrast to the claims of recent (...) critics, we show that methodological connections between the neurosciences and psychology are plausibly often the result of multiple realization. (shrink)

This work explores the increasing militarization of borders throughout the world, particularly the United States border with Mexico. Rather than further rhetoric of "border security," this work views increases in guards, technology and the building of walls as militarized action. The goal of this essay is to place the onus upon states to justify their actions at borders in ways that do not appeal to tropes of terrorism. This work then explores how a logic of security infiltrates philosophical discussions of (...) "the right to exclude," thereby curtailing the ability to see borders in any other way than as a locale that must be militarized. Specifically, I analyze the work of Michael Blake and his juridical theory of immigration restrictions. I argue that his work necessitates the walling of borders and removal of those who create new obligations for current members of existing political institutions. (shrink)

In the United States today, much interpersonal racism is driven by corrupt forms of self-preservation. Drawing from Jean- Jacques Rousseau, I refer to this as self-love racism. The byproduct of socially-induced racial anxieties and perceived threats to one’s physical or social wellbeing, self-love racism is the protective attachment to the racialized dimensions of one’s social status, wealth, privilege, and/or identity. Examples include police officer related shootings of unarmed Black Americans, anti-immigrant sentiment, and the resurgence of unabashed white supremacy. This form (...) of racism is defined less by the introduction of racism into the world and more on the perpetuation of racially unjust socioeconomic and political structures. My theory, therefore, works at the intersection of the interpersonal and structural by offering an account of moral complacency in racist social structures. My goal is to reorient the directionality of philosophical work on racism by questioning the sense of innocence at the core of white ways-of-being. (shrink)

This philosophical investigation interrogates the relationship between G.W.F. Hegel’s concept of the master-slave dialectic in The Phenomenology of Spirit and the critique and reformulation of it by Frantz Fanon in Black Skin, White Masks. As a means of contextualization and expansion of Hegel’s original textual account, I consider Susan Buck-Morss’ seminal defense through grounding the dialectic in Hegel’s possible historical knowledge of the Haitian Revolution. I maintain that despite a compelling picture, Buck-Morss’ insights are unable to fully vindicate Hegel from (...) the rebukes of Fanon, and as a result, Hegel’s phenomenology necessitates a concrete analysis of the actual conscious experiences of the racialized and colonized subject in order to realize its aims. In pursuit of this critical methodology, I develop the upshot and positive movement of Fanon’s critique through what I describe as a “phenomenology of flesh” in conversation with Maurice Merleau Ponty’s The Visible and the Invisible.

Conwy Lloyd Morgan (1852–1936) is widely regarded as the father of modern comparative psychology. Yet, Morgan initially had significant doubts about whether a genuine science of comparative psychology was even possible, only later becoming more optimistic about our ability to make reliable inferences about the mental capacities of non-human animals. There has been a fair amount of disagreement amongst scholars of Morgan’s work about the nature, timing, and causes of this shift in Morgan’s thinking. We argue that Morgan underwent two (...) quite different shifts of attitude towards the proper practice of comparative psychology. The first was a qualified acceptance of the Romanesian approach to comparative psychology that he had initially criticized. The second was a shift away from Romanes’ reliance on systematizing anecdotal evidence of animal intelligence towards an experimental approach, focused on studying the development of behaviour. We emphasize the role of Morgan’s evolving epistemological views in bringing about the first shift – in particular, his philosophy of science. We emphasize the role of an intriguing but overlooked figure in the history of comparative psychology in explaining the second shift, T. Mann Jones, whose correspondence with Morgan provided an important catalyst for Morgan’s experimental turn, particularly the special focus on development. We also shed light on the intended function of Morgan’s Canon, the methodological principle for which Morgan is now mostly known. The Canon can only be properly understood by seeing it in the context of Morgan’s own unique experimental vision for comparative psychology. (shrink)

This short article lays the foundation for a theory of migratorial disobedience and explains how pro-border advocates fetishize immigration law.

The developmental properties of organisms play important roles in the generation of variation necessary for evolutionary change. But how can individual development steer the course of evolution? To answer this question, we introduce developmental channeling as a disposition of individual organisms that shapes their possible developmental trajectories and evolutionary dappling as an evolutionary outcome in which the space of possible organismic forms is dappled—it is only partially filled. We then trace out the implications of the channeling-dappling framework for contemporary debates (...) in the philosophy of evolution, including evolvability, reciprocal causation, and the extended evolutionary synthesis.

The new immigration legislation will not achieve its ostensible goal. The criteria it proposes for new immigrants thinly conceal its racist motivations.

Theoretical frameworks concerning cell fate typically center on proximate causes to explain how cells know what type they are meant to become. While major advances in cell fate theory have been achieved by these mechanism-focused frameworks, there are some aspects of cell decision-making that require an evolutionary interpretation. While mechanistic biologists sometimes turn to evolutionary theory to gain insights about cell fate (cancer is a good example), it is not entirely clear in cell fate theory what insights evolutionary theory can (...) add, and why in some cases it is required for understanding cell fate. In this perspective we draw on our work on cellular mortality to illustrate how evolutionary theory provides an explanation for death being selected as one of the potential cell fates. Using our hypothesis for why some microbes in a community choose death as their fate, we suggest that some insights in cell fate theory are inaccessible to a theoretical framework that focuses solely on proximate causes.

To deserve credit for doing what is morally right, we must act from the right kinds of motives. Acting from the right kinds of motives involves responding both to the morally relevant reasons, by acting on these considerations, and to the morally relevant individuals, by being guided by appropriate attitudes of regard for them. Recent theories of the right kinds of motives have tended to prioritize responding to moral reasons. I develop a theory that instead prioritizes responding to individuals (through (...) appropriate attitudes of regard for them) and argue that it better accounts for the basic features of the right kinds of motives – what we most fundamentally care about in judging whether persons deserve moral credit.

Homology is a biological sameness relation that is purported to hold in the face of changes in form, composition, and function. In spite of the centrality and importance of homology, there is no consensus on how we should understand this concept. The two leading views of homology, the genealogical and developmental accounts, have significant shortcomings. We propose a new account, the hierarchical-dependency account of homology, which avoids these shortcomings. Furthermore, our account provides for continuity between special, general, and serial homology.

There is a puzzle about the very possibility of foreseen but unintended side effects, and solving this puzzle requires us to revise our basic picture of the structure of practical deliberation. The puzzle is that, while it seems that we can rationally foresee, but not intend, bringing about foreseen side effects, it also seems that we rationally must decide to bring about foreseen side effects and that we intend to do whatever we decide to do. I propose solving this puzzle (...) by rejecting the idea that we intend to do whatever we decide to do. My solution involves taking account of the underappreciated role that qualified intentions play in deliberation. I also argue that this solution fares better than those that instead reject the idea that we rationally must decide to bring about foreseen side effects, for these solutions are committed to rejecting the even more compelling idea that decisions rationally serve as the conclusions of practical deliberation.

Fitness plays many roles throughout evolutionary theory, from a measure of populations in the wild to a central element in abstract theoretical presentations of natural selection. It has thus been the subject of an extensive philosophical literature, which has primarily centered on the way to understand the relationship between fitness values and reproductive outcomes. If fitness is a probabilistic or statistical quantity, how is it to be defined in general theoretical contexts? How can it be measured? Can a single conceptual (...) model for fitness be offered that applies in all biological cases, or must fitness measures be case-specific? Philosophers have explored these questions over the last several decades, largely in the context of an influential definition of fitness proposed in the late 1970s: the propensity interpretation. This interpretation as first described undeniably suffers from significant difficulties, and debate regarding the tenability of amendments and alternatives to it remains unsettled. (shrink)

The compelling, widely-accepted Satisfaction-is-Truth Principle says that if S wants p, then S has a desire that's satisfied in exactly the worlds where p is true. We reject the Principle; an agent may want p without having a desire that's satisfied when p obtains in any old way. Other theorists who reject the Principle rely on contested intuitions about when agents get what they want. We instead appeal to—and shed new light on—the dispositional role of desire.

Philosophy of science is expanding via the introduction of new digital data and tools for their analysis. The data comprise digitized published books and journal articles, as well as heretofore unpublished material such as images, archival text, notebooks, meeting notes, and programs.

In this article, we survey the state of digital work in the philosophy of (...) science, showing what kinds of questions can be answered and how one can go about answering them. (shrink)

Gilles Deleuze and Félix Guattari, writing together from 1972 to 1992, developed a robust body of theoretical work exemplar of the French poststructuralist tradition. Through their magnum opus, a two-part series entitled “Capitalism and Schizophrenia,” they interrogated the nature of desire, the organizational schemas of society, and the metaphysical structure of the world. Yet, despite claiming to have produced a thoroughly egalitarian project, their work is subject to a variety of exclusionary developments and cultural limitations. This paper attempts to traverse (...) these deficiencies through speculative ecological and theological engagements with the work of Deleuze and Guattari. These engagements begin with the development of “schizoanalytical theology,” an application of their theory of schizoanalysis which disrupts transcendental views of divinity to ground spirituality in the creativity of desire and variability of ecological processes. This is followed by an exploration of the theories of Édouard Glissant, a Francophone theorist from Martinique whose work, heavily influenced by Deleuze and Guattari, is centered around the development of an ontology consistent with the cultural experiences of the colonized. Glissant’s interpretation of, and departure from, Deleuze and Guattari is explored for insights into how their theory may corrected and refigured to be responsive to the nuances of both minority perspectives and the ecological crisis. The paper is closed with a dialogue between Guattari’s theory of “ecosophy” and Glissant’s socio-cultural views on ecology, showing the application, and flexibility, of schizoanalytical theology to a variety of modern crises which find their culmination in ecological degradation.

Suppose you think that whether you believe some proposition A at some future time t might have a causal influence on whether A is true. For instance, maybe you think a woman can read your mind, and either (1) you think she will snap her fingers shortly after t if and only if you believe at t that she will, or (2) you think she will snap her fingers shortly after t if and only if you don't believe at t (...) that she will. Let A be the proposition that she snaps her fingers shortly after t. In case (1), theoretical rationality seems to leave it open whether you should believe A or not. Perhaps, for all it has to say, you could just directly choose whether to believe A. David Velleman seems to be committed to something close to that, but his view has been unpopular. In case (2), you seem to be in a theoretical dilemma, a situation where any attitude you adopt toward A will be self-undermining in a way that makes you irrational. Such theoretical dilemmas ought to be impossible, just as genuine moral dilemmas ought to be impossible, but it is surprisingly hard to show that they are (perhaps because they aren't). I study cases analogous to (1) and (2) in a probabilistic framework where degrees of belief rather than all-or-nothing beliefs are taken as basic. My principal conclusions are that Velleman's view is closer to the truth than it is generally thought to be, that case (2) type theoretical dilemmas only arise for hyperidealised agents unlike ourselves, and that there are related cases that can arise for agents like us that are very disturbing but might not quite amount to theoretical dilemmas.

Abstract: The State of Nature, Prehistory, and Mythmaking Karl Widerquist This chapter provide an overview of two books, in which Grant S. McCall and I name, define, and debunk the following false claims that still play important roles in contemporary political theories although they are not always defined and defended explicitly: 1. The Hobbesian hypothesis: sovereign states and/or the liberal private property rights system benefits everyone (or at least harms no one) relative to how well they could reasonably expect (...) to live in the state of nature—i.e. a society lacking one or both of these institutions. 2. The appropriation hypothesis: private property in the form of liberal ownership rights develops naturally while collective, communal, common, or government-held property rights systems do not. 3. The natural inequality hypothesis: inequality is natural and inevitable, i.e. economic, social, and/or political equality cannot exist and/or cannot be created without a significant loss in negative freedom. 4. The market-freedom hypothesis: a market economy (and/or capitalism) is more consistent with negative freedom than any other economic system. The third and fourth of these claims are not obviously claims about prehistoric or small-scale societies, but they are universal claims about all societies and so they include claims about even the most remote and distant societies from contemporary thinking.

The propensity interpretation of fitness (PIF) is commonly taken to be subject to a set of simple counterexamples. We argue that three of the most important of these are not counterexamples to the PIF itself, but only to the traditional mathematical model of this propensity: fitness as expected number of offspring. They fail to demonstrate that a new mathematical model of the PIF could not succeed where this older model fails. We then propose a new formalization of the PIF that (...) avoids these (and other) counterexamples. By producing a counterexample-free model of the PIF, we call into question one of the primary motivations for adopting the statisticalist interpretation of fitness. In addition, this new model has the benefit of being more closely allied with contemporary mathematical biology than the traditional model of the PIF. (shrink)

Claims that our species is an “evolutionary success” typically do not feature prominently in academic articles. However, they do seem to be a recurring trope in science popularization. Why do we seem to be attracted to viewing human evolution through the lense of “success”? In this chapter we discuss how evolutionary success has both causal-descriptive and ethical-normative components, and how its ethical status is ambiguous, with possible hints of anthropocentrism. We also place the concept of “success” in a wider context (...) of biological thought, contrasting it with two other value-laden concepts: evolutionary progress and human uniqueness. Claiming the human species to be an evolutionary success is ostensibly grounded in metrics such as the dominance or the size of the human population, but often goes beyond this, suggesting that humans are a unique species or the pinnacle of evolutionary progress.

This article argues the following points. The Hobbesian hypothesis, which we define as the claim that all people are better off under state authority than they would be outside of it, is an empirical claim about all stateless societies. It is an essential premise in most contractarian justifications of government sovereignty. Many small-scale societies are stateless. Anthropological evidence from them provides sufficient reason to doubt the truth of the hypothesis, if not to reject it entirely. Therefore, contractarian theory has not (...) done what it claims to do: it has not justified state sovereignty to each person subject to it by demonstrating that they benefit from that authority. To be justified in contractarian terms, states have to do something to improve the living standards of disadvantaged people under their rule. (shrink)

This paper examines the ethics of the Australian business community’s responses to the phenomenon of modern slavery. Engaging a critical discourse approach, we draw upon a data set of submissions by businesses and business representatives to the Australian government’s Joint Standing Committee on Foreign Affairs, Defence and Trade ‘Parliamentary Inquiry into Establishing a Modern Slavery Act in Australia’—which preceded the signing into law of Australia’s Modern Slavery Act 2018—to examine the business community’s discursive construction in their submissions of the ethical–political (...) concept of freedom. The paper shows how the concept of freedom was employed by Australian business in a manner that privileged their own subject status and advocated for legislation with minimal burden. Relating this contemporary case to a longer historical context, we show how Australian business responses towards modern slavery map onto liberal and neoliberal ethics in which the freedom of the propertied takes precedent over that of the property-less. Further, we show discursive similarities in the arguments presented by modern Australian businesses and certain historical efforts by members of the business community to privilege commercial freedoms in responses to 18th and 19th Century abolitionist movements. Overall, our research makes two important contributions: first, it highlights the value of a critical discourse lens in business ethics research to show how business and other stakeholders in the field construct and shape their own and other’s ethically-laden understanding of reality; and second, it presents a case for considerable scepticism about the motivation of business to employ the freedoms made available to it under neo/liberal discourse to confront a key human rights challenge.

The levels of selection debate is generally taken to be a debate about how natural selection can occur at the various levels of biological organization. In this paper, we argue that questions about levels of selection should be analyzed separately from questions about levels of organization. In the deflationary proposal we defend, all that is necessary for multilevel selection is that there are cases in which particles are nested in collectives, and that both the collectives and the particles that compose (...) them each separately undergo natural selection. We argue that adopting this deflationary account helps to disentangle the levels of selection and the levels of organization, and thereby contributes to advancing the levels of selection debate.

Organismal death is foundational to the evolution of life, and many biological concepts such as natural selection and life history strategy are so fashioned only because individuals are mortal. Organisms, irrespective of their organization, are composed of basic functional units—cells—and it is our understanding of cell death that lies at the heart of most general explanatory frameworks for organismal mortality. Cell death can be exogenous, arising from transmissible diseases, predation, or other misfortunes, but there are also endogenous forms of death (...) that are sometimes the result of adaptive evolution. These endogenous forms of death—often labeled programmed cell death, PCD—originated in the earliest cells and are maintained across the tree of life. Here, we consider two problematic issues related to PCD (and cell mortality generally). First, we trace the original discoveries of cell death from the nineteenth century and place current conceptions of PCD in their historical context. Revisions of our understanding of PCD demand a reassessment of its origin. Our second aim is thus to structure the proposed origin explanations of PCD into coherent arguments. In our analysis we argue for the evolutionary concept of PCD and the viral defense-immunity hypothesis for the origin of PCD. We suggest that this framework offers a plausible account of PCD early in the history of life, and also provides an epistemic basis for the future development of a general evolutionary account of mortality.

Niche construction is the process of organisms changing themselves or their environment—or their relationship with their environment—in ways that affect the evolutionary trajectory of their population. These evolutionary trajectory changes are traditionally understood to be triggered by changes in selection pressures. Niche construction thus necessarily involves organisms altering selection pressures. In this paper, we argue that changes in selection pressures is not the only way organisms can influence the evolutionary futures of their population. We propose that organisms can also affect (...) drift probabilities, and that such changes should be considered niche construction. Drift probabilities can be modulated by altering population size or by affecting driftability (individual variance in possible reproductive outcomes). We consider both and provide examples of how niche construction can stabilize, increase, or dampen drift probabilities. Finally, we revisit and broaden the traditional definition of niche construction. We hold that organismic activities that modify drift probabilities should count as niche construction, even if selection pressures remain unaltered. (shrink)

Milgram’s experiments, subjects were induced to inflict what they believed to be electric shocks in obedience to a man in a white coat. This suggests that many of us can be persuaded to torture, and perhaps kill, another person simply on the say-so of an authority figure. But the experiments have been attacked on methodological, moral and methodologico-moral grounds. Patten argues that the subjects probably were not taken in by the charade; Bok argues that lies should not be used in (...) research; and Patten insists that any excuse for Milgram’s conduct can be adapted on behalf of his subjects. (Either he was wrong to conduct the experiments or they do not establish the phenomenon of immoral obedience). We argue a) that the subjects were indeed taken in b) that there are good historical reasons for regarding the experiments as ecologically valid, c) that lies (though usually wrong) were in this case legitimate, d) that there were excuses available to Milgram which were not available to his subjects and e) that even if he was wrong to conduct the experiments this does not mean that he failed to establish immoral obedience. So far from ‘disrespecting’ his subjects, Milgram enhanced their autonomy as rational agents. We concede however that it might (now) be right to prohibit what it was (then) right to do. (shrink)

"Correlation is not causation" is one of the mantras of the sciences—a cautionary warning especially to fields like epidemiology and pharmacology where the seduction of compelling correlations naturally leads to causal hypotheses. The standard view from the epistemology of causation is that to tell whether one correlated variable is causing the other, one needs to intervene on the system—the best sort of intervention being a trial that is both randomized and controlled. In this paper, we argue that some purely correlational (...) data contains information that allows us to draw causal inferences: statistical noise. Methods for extracting causal knowledge from noise provide us with an alternative to randomized controlled trials that allows us to reach causal conclusions from purely correlational data. (shrink)

In a recent study, we found a negative association between psychopathy and violence against genetic relatives. We interpreted this result as a form of nepotism and argued that it failed to support the hypothesis that psychopathy is a mental disorder, suggesting instead that it supports the hypothesis that psychopathy is an evolved life history strategy. This interpretation and subsequent arguments have been challenged in a number of ways. Here, we identify several misunderstandings regarding the harmful dysfunction definition of mental disorder (...) as it applies to psychopathy and regarding the meaning of nepotism. Furthermore, we examine the evidence provided by our critics that psychopathy is associated with other disorders, and we offer a comment on their alternative model of psychopathy. We conclude that there remains little evidence that psychopathy is the product of dysfunctional mechanisms. (shrink)

In written and spoken communications, figures of speech (e.g., metaphors and synecdoche) are often used as an aid to help convey abstract or less tangible concepts. However, the benefits of using rhetorical illustrations or embellishments in visualization have so far been inconclusive. In this work, we report an empirical study to evaluate hypotheses that visual embellishments may aid memorization, visual search and concept comprehension. One major departure from related experiments in the literature is that we make use of a dual-task (...) methodology in our experiment. This design offers an abstraction of typical situations where viewers do not have their full attention focused on visualization (e.g., in meetings and lectures). The secondary task introduces “divided attention”, and makes the effects of visual embellishments more observable. In addition, it also serves as additional masking in memory-based trials. The results of this study show that visual embellishments can help participants better remember the information depicted in visualization. On the other hand, visual embellishments can have a negative impact on the speed of visual search. The results show a complex pattern as to the benefits of visual embellishments in helping participants grasp key concepts from visualization. (shrink)
