In a conversation I was having with a friend the other day, I was telling her that, in all likelihood, the journal SubStance will survive its founders. It is not the possibility of survival that I ruminated about for the next few days. After all, there are many a journal that survived, some of them for centuries. But it is the word "survive" that kept busying itself in my mind. Why do we use metaphors of life and death to talk (...) about just about everything? Look around you and you'll see how pervasive it is, from what we say of the "lifespan" of an institution to the trite "Live TV," just to name a couple of examples that immediately come to mind. And not to forget, of course, the just as pervasive efforts in... Read More. (shrink)

“Beer Gut Gene Discovered” announced the Sydney Morning Herald in 2003 (January 9)—yet another media declaration that scientists have uncovered the “gene for” such-and-such. Claims such as these are, in the popular consciousness, often conflated with proposals from sociobiologists and evolutionary psychologists regarding the innateness of certain human traits: infanticide, rape, or intelligence correlated with gender or race. When these traits are nasty or politically disconcerting (as are the three listed) then those pressing the claims are usually quick to (...) point out that to identify any such tendency as the manifestation of an evolutionary adaptation is in no sense to exonerate the behaviour or to justify any political arrangement designed to accommodate it. Often, however, though we may not be quite able to articulate where this defence fails, we are left feeling uneasy. (shrink)

Harris (bio)For Sydney Levy, who brought me on board.Geologic AspirationsStone breathes within nature's time cycle…. It begins before you and continues through you and goes on. Working with stone is not resisting time but touching it.—Isamu NoguchiUnder the suffocating circumstances of lockdown, COVID conditions inevitably wafted their way into the stoned thinking of Pierre Jardin.2 The pandemic atmosphere made air apparent, and breathing became (...) personal, political, and planetary. People sought perspective in sometimes surprising ways. While many turned to the Stoics, Jardin turned to stone. Suspending his disbelief in "The Hammock of Relaxation" (fig. 1), Jardin stretched his imagination, and set himself adrift in diffuse reveries of rocky respiration. Click for larger view View full resolutionFigure 1.The Hammock of Relaxation. Pebble on book cover.Photo by author.Jardin composes a life centered in absorbing stone(s), encompassing both a physical process of soaking in a substance slowly and psychological experience of becoming engrossed in it. He feels alive with stone and stone alive in him; literally and metaphorically, he has spent hours looking at stone, listening to stone, and touching/being touched by stone. But he had never seriously considered breathing stone. Immediately, a slew of questions arose: Do rocks breathe? Do mountains? Does the Earth? What would it mean to breathe with a stone, or with the planet? Jardin's pursuit of lithic and lithospheric respirations came to comprise his geologic aspirations, which are set out here. [End Page 261]Aerial ImaginationPierre Jardin's geologic aspirations took inspiration from Gaston Bachelard's aerial imagination, as described in Air and Dreams. Accepting Bachelard's invitation to "listen to nothing but our own breathing…, to become as aerial as our breath…" (Bachelard, Air 241), Jardin set about inventing a regimen of contemplative breathing exercises. To do so, he took up what Bachelard terms the "search for a thought hidden under expressive sedimen,ts, [in which] a geology of silence is developed" (Bachelard Air, 251). The question was, what "expressive sediments" should Jardin mine in this quixotic quest? What materials and mental modalities would precipitate a "geology of silence"?In order to meld minds with Bachelard, Jardin placed a pebble on Robert Lapoujade's pencil portrait that graces the book's cover (fig. 2). The results were alchemical: the cobble transmuted into a philosopher's stone, opening Bachelard's third eye; the rock launched a basalt on Jardin's senses that produced an "intoxication of aerial imagination raised to its cosmic role" (Bachelard, Air 241). A gesture as simple as placing a rock on a book crystallized new quartz-veins of thought. What follows are Jardin's experiments with a variety of "expressive sediments," a series of multi-scalar meditations and various instantiations of lithic respiration.

Pebble on book cover.Photo by author.Atmospheric CompositionsPierre Jardin's geologic aspirations began with a Composition of Place, a meditative technique deployed in the Spiritual Exercises of Ignatius of Loyola. Loyola stipulates that "for contemplation or meditation about visible things… the 'composition' will consist in seeing through the gaze of the imagination the material place where the object I want to contemplate is situated" (Ganss 47). Taking "Breathing with Mountains" as the "object" of contemplation stretches Jardin's imagination to a geologic scale; its "material place" is the Earth's atmosphere, or more specifically, its lowest layer, the troposphere. [End Page 262]To facilitate his meditation, Jardin scales Earth down to a stunning serpentine stone, which he has mounted like a globe. Holding the stone and breathing slowly, Jardin can visualize the troposphere as the thinnest of films on the rock's surface. In his active imagination, the bumps, furrows, and ridges in the rough rock texture evoke the constant crumpling of the lithosphere caused by drifting and crashing tectonic plates.With the stone standing in for Earth, Jardin suddenly becomes a geologic giant representing Anthropocene humanity. As his exhalations cloud the stone, Jardin considers how Anthropogenic expirations are changing the composition of the Earth's atmosphere. An index of human impact is provided... (shrink)

In the best of cases, indeed, the author has produced his œuvre precisely to confront the unknown and face the deadly monsters (...) that make the labyrinths worth exploring in the first place. The reader of the work, or watcher of the painting or film, cannot escape the perilous attraction of the cognitive maelstrom he, hesitantly or trustfully, enters at his own risk. Every word or stroke on canvas or chord or instant shutter of the camera or unending gros plan may hide unexpected doors to impossible worlds, each of them possible nonetheless. Love, hate, crime, lust, power, etc.: every facet of human experience can become scary or exciting forces to be faced, for just an instant or for an inconclusive lifelong struggle. Time is possibly the most intractable of those forces as only unconceivable gods can make of it their plaything. Similar to the desert planet of Frank Herbert's Dune, it harbors unpredictable monsters that destroy anything that moves—unless one learns to dance in an equally unpredictable fashion, winning a reprieve only to end up inescapably a fatality, having met the unavoidable fatum.SubStance has been travelling a much populated and cacophonic desert for fifty years, maintaining, despite the times' ubuesque twists and turns, its acrobatic démarche and tracing its empirical path through the intellectual dunes of two or three generations, collecting as it went many stimulating spices that it shared, avoiding its sale to the highest academic bidder.

In the past two decades, epistemologists have significantly expanded the focus of their field. To the traditional question that has dominated the debate — under what conditions does belief amount to knowledge? — they have added questions about testimony, epistemic virtues and vices, epistemic trust, and more. This broadening of the range of epistemic concern has coincided with an expansion in conceptions of epistemic agency beyond the individualism characteristic of most earlier epistemology. We believe that these developments have not gone (...) far enough. While the weak anti-individualism we see in contemporary epistemology may be adequate for the kinds of cases it tends to focus on, a great deal of human knowledge production and transmission does not conform to these models. Furthermore, the dispositions and norms that are knowledge-conducive in the familiar cases may not be knowledge-conducive generally. In fact, dispositions that, at an individual level, count as epistemic vices may be epistemic virtues in common social contexts. We argue that this overlooked feature of human social life means that epistemology must become more deeply and pervasively social. (shrink)

The accusation of virtue signalling is typically understood as a serious charge. Those accused usually respond by attempting to show that they are doing no such thing. In this paper, I argue that we ought to embrace the charge, rather than angrily reject it. I argue that this response can draw support from cognitive science, on the one hand, and from social epistemology on the other. I claim that we may appropriately concede that what we are doing is virtue signalling, (...) because virtue signalling is morally appropriate. It neither expresses vices, nor is hypocritical, nor does it degrade the quality of public moral discourse. Signalling our commitment to norms is a central and justifiable function of moral discourse, and the same signals provide evidence that is appropriately taken into account in forming moral beliefs.

Much of what we know we know through testimony, and knowing on the basis of testimony requires some degree of trust in speakers. Trust is therefore very valuable. But in trusting, we expose ourselves to risks of harm and betrayal. It is therefore important to trust well. In this paper, I discuss two recent cases of the betrayal of trust in (broadly) academic contexts: one involving hoax submissions to journals, the other faking an identity on social media. I consider whether (...) these betrayals suggest that we ought to be less trusting in contexts like these. I argue that we should not: the acquisition of knowledge is dependent on trust, and we cannot intentionally reduce the extent to which we trust in these kinds of contexts without risking destroying it utterly. Instead, we must trust in our epistemic networks and the way they work to filter out deception. (shrink)

Accounts of moral responsibility can be divided into those that claim that attributability of an act, omission, or attitude to an agent is sufficient for responsibility for it, and those which hold that responsibility depends crucially on choice. I argue that accounts of the first, attributionist, kind fail to make room for the relatively stringent epistemic conditions upon moral responsibility, and that therefore an account of the second, volitionist, kind ought to be preferred. I examine the various arguments advanced on (...) behalf of attributionist accounts, and argue that for each of them volitionism has a reply that is in every case at least as, and often more, persuasive. Most significantly, only volitionism can accommodate the intuitively important distinction between the bad and the blameworthy. (shrink)

Discussions of virtue signaling to date have focused exclusively on the signaling of the moral virtues. This article focuses on intellectual virtue signaling: the status-seeking advertising of supposed intellectual virtues. Intellectual virtue signaling takes distinctive forms. It is also far more likely to be harmful than moral virtue signaling, because it distracts attention from genuine expertise and gives contrarian opinions an undue prominence in public debate. The article provides a heuristic by which to identify possible instances of intellectual virtue signaling. (...) When people with no relevant expertise rapidly move to offer their opinions on a wide range of topics as soon as these topics become fashionable or newsworthy, and especially when these opinions are contrarian, we should suspect them of intellectual virtue signaling.

Governments, physicians, media and academics have all called for individuals to bear responsibility for their own health. In this article, I argue that requiring those with adverse health outcomes to bear responsibility for these outcomes is a bad basis for policy. The available evidence strongly suggests that the capacities for responsible choice, and the circumstances in which these capacities are exercised, are distributed alongside the kinds of goods we usually talk about in discussing distributive justice, and this distribution significantly explains (...) why people make bad health choices. These facts suggest that we cannot justifiably hold them responsible for these choices. We do better to hold responsible those who determine the ways in which capacities and circumstances are distributed: they are indirectly responsible for these adverse health outcomes and possess the capacities and resources to take responsibility for these facts.

Design thinking in general, and optimality modeling in particular, have traditionally been associated with adaptationism—a research agenda that gives pride of place to natural selection in shaping biological characters. Our goal is to evaluate the role of design thinking in non-evolutionary analyses. Specifically, we focus on research into abstract design principles that underpin the functional organization of extant organisms. Drawing on case studies from engineering-inspired approaches in biology we show how optimality analysis, and other design-related methods, play a specific methodological (...) role that is tangential to the study of adaptation. To account for the role of these reasoning strategies in contemporary biology, we therefore suggest a reevaluation of the connection between design thinking and adaptationism. (shrink)

Neil Van Leeuwen argues that many religious people do not act and infer as we would expect believers to act and infer, and on this basis argues that they are not genuine believers. They take some other, nondoxastic, attitude to the claims they profess to believe. In this short commentary, I argue that in many (but far from all) such cases, the content, and not the attitude, explains the departures from the inferential and behavioral stereotype we associate with belief.

I distinguish three theses associated with the new mechanistic philosophy – concerning causation, explanation and scientific methodology. Advocates of each thesis are identified and relationships among them are outlined. I then look at some recent work on natural selection and mechanisms. There, attention to different kinds of New Mechanism significantly affects of what is at stake.

Proposals for regulating or nudging healthy choices are controversial. Opponents often argue that individuals should take responsibility for their own health, rather than be paternalistically manipulated for their own good. In this paper, I argue that people can take responsibility for their own health only if they satisfy certain epistemic conditions, but we live in an epistemic environment in which these conditions are not satisfied. Satisfying the epistemic conditions for taking responsibility, I argue, requires regulation of this environment. I describe (...) some proposals for such regulation and show that we cannot reject all regulation in the name of individual responsibility. We must either regulate individuals’ healthy choices or regulate the epistemic environment. (shrink)

The Hodgkin–Huxley (HH) model of the action potential is a theoretical pillar of modern neurobiology. In a number of recent publications, Carl Craver ([2006], [2007], [2008]) has argued that the model is explanatorily deficient because it does not reveal enough about underlying molecular mechanisms. I offer an alternative picture of the HH model, according to which it deliberately abstracts from molecular specifics. By doing so, the model explains whole-cell behaviour as the product of a mass of underlying low-level events. The (...) issue goes beyond cellular neurobiology, for the strategy of abstraction exhibited in the HH case is found in a range of biological contexts. I discuss why it has been largely neglected by advocates of the mechanist approach to explanation. 1 Introduction2 A Primer on the HH Model2.1 The basic qualitative picture2.2 The quantitative model3 Interlude: What Did Hodgkin and Huxley Think?4 Craver’s View4.1 Mechanistic explanation4.2 Sketches4.3 Craver's view: The HH model as a mechanism sketch5 An Alternative View of the HH Model5.1 Another look at the equations5.2 The discrete-gating picture5.3 The road paved by Hodgkin and Huxley5.4 Summary and comparison to Craver6 Conclusion: The HH Model and Mechanistic Explanation6.1 Sketches and abstractions6.2 Why has aggregative abstraction been overlooked?

A number of philosophers have recently argued that agents need not be conscious of the reasons for which they act or the moral significance of their actions in order to be morally responsible for them. In this paper, I identify a kind of awareness that, I claim, agents must have in order to be responsible for their actions. I argue that conscious information processing differs from unconscious in a manner that makes the following two claims true: (1) an agent’s values (...) ought to be identified with attitudes of which she is conscious, because having a value entails having a set of dispositions produced by conscious attitudes alone, and (2) that only actions settled upon by conscious deliberation are deeply attributable to agents, because only such actions express the agent’s evaluative stance.

Children, even very young children, distinguish moral from conventional transgressions, inasmuch as they hold that the former, but not the latter, would still be wrong if there was no rule prohibiting them. Many people have taken this finding as evidence that morality is objective, and therefore universal. I argue that reflection on the phenomenon of imaginative resistance will lead us to question these claims. If a concept applies in virtue of the obtaining of a set of more basic facts, then (...) it is authority independent, and we therefore resist the attempts of authorities to claim that it does not apply. Thus, the moral/conventional distinction is a product of imaginative resistance to claims that a concept does not apply when its supervenience base is in place (or vice versa). All we can rightfully conclude from the fact that children are disposed to make the moral/conventional distinction is that our moral concepts belong to the class of authority-independent concepts. Though the set of basic facts in virtue of which an authority-independent concept obtains must be objective, the concept itself might be conventional, inasmuch as we could easily draw its boundaries wider or narrower, or fail to have a concept that corresponds to these properties at all.

ABSTRACT Should surgeons be permitted to amputate healthy limbs if patients request such operations? We argue that if such patients are experiencing significant distress as a consequence of the rare psychological disorder named Body Integrity Identity Disorder (BIID), such operations might be permissible. We examine rival accounts of the origins of the desire for healthy limb amputations and argue that none are as plausible as the BIID hypothesis. We then turn to the moral arguments against such operations, and argue that (...) on the evidence available, none is compelling. BIID sufferers meet reasonable standards for rationality and autonomy: so as long as no other effective treatment for their disorder is available, surgeons ought to be allowed to accede to their requests.

ABSTRACTExperimentation is traditionally considered a privileged means of confirmation. However, why and how experiments form a better confirmatory source relative to other strategies is unclear, and recent discussions have identified experiments with various modeling strategies on the one hand, and with ‘natural’ experiments on the other hand. We argue that experiments aiming to test theories are best understood as controlled investigations of specimens. ‘Control’ involves repeated, fine-grained causal manipulation of focal properties. This capacity generates rich knowledge of the object investigated. (...) ‘Specimenhood’ involves possessing relevant properties given the investigative target and the hypothesis in question. Specimens are thus representative members of a class of systems, to which a hypothesis refers. It is in virtue of both control and specimenhood that experiments provide powerful confirmatory evidence. This explains the distinctive power of experiments: although modelers exert extensive control, they do not exert this control over specimens; although natural experiments utilize specimens, control is diminished.

It’s widely held that a lack of intellectual humility is part of the reason why flagrantly unjustified beliefs proliferate. In this paper, I argue that an excess of humility also plays a role in allowing for the spread of misinformation. Citing experimental evidence, I show that inducing intellectual humility causes people inappropriately to lower their confidence in beliefs that are actually justified for them. In these cases, they manifest epistemic humility in ways that make them epistemically worse off. I argue (...) that epistemic humility may fail to promote better beliefs because it functions for us against the background of our individualistic theory of responsible epistemic agency: until we reject such theories, intellectual humility is as much a problem as a solution to epistemic ills. Virtue epistemology is inadequate as a response to unjustified beliefs if it does not look beyond the virtues to our background beliefs. (shrink)

I argue for three conclusions. First, responsibility skeptics are committed to the position that the criminal justice system should adopt a universal nonresponsibility excuse. Second, a universal nonresponsibility excuse would diminish some of our most deeply held values, further dehumanize criminals, exacerbate mass incarceration, and cause an even greater number of innocent people (nonwrongdoers) to be punished. Third, while Saul Smilansky's ‘illusionist’ response to responsibility skeptics – that even if responsibility skepticism is correct, society should maintain a responsibility‐realist/retributivist criminal justice (...) system – is generally compelling, it would not work if a majority of society were to convert, theoretically and psychologically, to responsibility skepticism. In this (highly improbable) scenario, and only in this (highly improbable) scenario, the criminal justice system would need to be reformed in such a way that it aligned with the majority's responsibility‐skeptical beliefs and attitudes.

According to the ego-depletion account of loss of self-control, self-control is, or depends on, a depletable resource. Advocates of this account have argued that what is depleted is actually glucose. However, there is experimental evidence that indicates that glucose replenishment is not necessary for regaining self-control, as well as theoretical reasons for thinking that it is not depleted by exercises of self-control. I suggest that glucose restores self-control not because it is a resource on which it relies, but because it (...) serves as a signal of environment quality. I suggest that the evidence is better explained by a rival opportunity costs model of self-control than by the ego-depletion account. (shrink)

In the wake of the spectacular success of Miranda Fricker's Epistemic Injustice, philosophers have paid a great deal of attention to testimonial injustice. Testimonial injustice occurs when recipients of testimony discount it in virtue of its source: usually, their social identity. The remedy for epistemic injustice is almost always listening better and giving greater weight to the testimony we hear, on most philosophers' implicit or explicit view. But Fricker identifies another kind of epistemic injustice: hermeneutical injustice. This kind of injustice (...) occurs when someone can't articulate their own experience or understand their situation for lack of the hermeneutical tools. There is a possible tension between these kinds of injustice, we suggest: sincere testimony may be misleading (may fail to identify significant harms the testfier is subject, or may fail to register its magnitude, or to categorize it as the kind of harm it is) in virtue of a lack of hermeneutical resources. This tension raises the possibility that there are situations in which experts - those who possess hermeneutical tools - may be able to correct the testimony of those who experience harms in virtue of their identity. In this paper, we identify possible cases in which epistemic injustice might be reduced through such correction: in which an increase in testimonial injustice might serve to decrease it in the longer run, for example. We also suggest how the obvious dangers of a too great readiness to see testimony as in need of expert correction might be mitigated, and how the expert might suggest corrections without ceasing to listen.

Hunting and gathering is, evolutionarily, the defining subsistence strategy of our species. Studying how children learn foraging skills can, therefore, provide us with key data to test theories about the evolution of human life history, cognition, and social behavior. Modern foragers, with their vast cultural and environmental diversity, have mostly been studied individually. However, cross-cultural studies allow us to extrapolate forager-wide trends in how, when, and from whom hunter-gatherer children learn their subsistence skills. We perform a meta-ethnography, which allows us (...) to systematically extract, summarize, and compare both quantitative and qualitative literature. We found 58 publications focusing on learning subsistence skills. Learning begins early in infancy, when parents take children on foraging expeditions and give them toy versions of tools. In early and middle childhood, children transition into the multi-age playgroup, where they learn skills through play, observation, and participation. By the end of middle childhood, most children are proficient food collectors. However, it is not until adolescence that adults (not necessarily parents) begin directly teaching children complex skills such as hunting and complex tool manufacture. Adolescents seek to learn innovations from adults, but they themselves do not innovate. These findings support predictive models that find social learning should occur before individual learning. Furthermore, these results show that teaching does indeed exist in hunter-gatherer societies. And, finally, though children are competent foragers by late childhood, learning to extract more complex resources, such as hunting large game, takes a lifetime. (shrink)

In a recent paper in this journal, Joshua Blanchard has identified a novel problem: the problem of unwelcome epistemic company. We find ourselves in unwelcome epistemic company when we hold a belief that is also held mainly or most prominently by those we regard as morally or epistemically bad. Blanchard argues that some, but not all, unwelcome epistemic company provides higher-order evidence against our belief. But he doesn't provide a test for when company is unwelcome or a diagnosis of why (...) it is unwelcome. I provide both. On my disjunctive test, unwelcome epistemic company provides us with a defeater when either there is a match between the content of the belief and the properties that make our company unwelcome, or there is reason to suspect that the belief arose via a shared, unreliable, causal process.

Conciliationism—the thesis that when epistemic peers discover that they disagree about a proposition, both should reduce their confidence—faces a major objection: it seems to require us to significantly reduce our confidence in our central moral and political commitments. In this paper, I develop a typology of disagreement cases and a diagnosis of the source and force of the pressure to conciliate. Building on Vavova’s work, I argue that ordinary and extreme disagreements are surprising, and for this reason, they carry information (...) about the likelihood of error. But deep disagreement is not surprising at all, and token deep disagreements do not put pressure on us to conciliate. However, a pattern of deep disagreements points to a different concern: not the problem of disagreement but the problem of irrelevant influences. Deep disagreement constitutes some pressure to examine the foundations from which we reason, rather than to conciliate on our central moral and political claims. (shrink)

Libertarianism seems vulnerable to a serious problem concerning present luck, because it requires indeterminism somewhere in the causal chain leading to directly free action. Compatibilism, in contrast, is thought to be free of this problem, as not requiring indeterminism in the causal chain. I argue that this view is false: compatibilism is subject to a problem of present luck. This is less of a problem for compatibilism than for libertarianism. However, its effects are just as devastating for one kind of (...) compatibilism, the kind of compatibilism which is history‐sensitive, and therefore must take the problem of constitutive luck seriously. The problem of present luck confronting compatibilism is sufficient to undermine the history‐sensitive compatibilist's response to remote – constitutive – luck. (shrink)

There has been a resurgence of interest lately within philosophy of mind and action in the category of mental action. Against this background, the present paper aims to question the very possibility, or at least the theoretical significance, of teasing apart mental and bodily acts. After raising some doubts over the viability of various possible ways of drawing the mental act/bodily act distinction, the paper draws some lessons from debates over embodied cognition, which arguably further undermine the credibility of the (...) distinction. The insignificance of the distinction is demonstrated in part by showing how the focus on ‘inner’ acts hampers fruitful discussion of Galen Strawson’s skepticism of mental agency. Finally, the possibility is discussed that a distinction between covert and overt action should supplant the one between mental and bodily action. (shrink)
