All organisms live in close association with microbes. However, not all such associations are meaningful in an evolutionary context. Current debate concerns whether hosts and microbes are best described as communities of individuals or as holobionts (selective units of hosts plus their microbes). Recent reports that assortative mating of hosts by diet can be mediated by commensal gut microbes have attracted interest as a potential route to host reproductive isolation (RI). Here, the authors discuss logical problems with this line of (...) argument. The authors briefly review how microbes can affect host mating preferences and evaluate recent findings from fruitflies. Endosymbionts can potentially influence host RI given stable and recurrent co‐association of hosts and microbes over evolutionary time. However, observations of co‐occurrence of microbes and hosts are ripe for misinterpretation and such associations will rarely represent a meaningful holobiont. A framework in which hosts and their microbes are independent evolutionary units provides the only satisfactory explanation for the observed range of effects and associations. (shrink)

In this paper I challenge the received view of the relationship between Kierkegaard and Heidegger and explore the relationship between phenomenology and theology. Against the received view—the familiar claim that Heidegger “secularizes” Kierkegaard—I argue that both philosophers attempt to uncover the existential conditions for the possibility of an authentic existence and take the passionate religious life to be one form of such an existence. Therefore, Heidegger’s concept of resoluteness does not represent a secularized break with but rather aphenomenological development of (...) Kierkegaard’s concept of inwardness; and both concepts represent a mode of existence that is the condition for the possibility of genuine Christian faith. This grounding relationship between resoluteness and faith, I argue, is representative of Heidegger’s view of the relationship between phenomenological and theological concepts in general. Thus, my argument not only sheds light onHeidegger’s development of Kierkegaard but it also clarifies some important features of the relationship between phenomenology and theology. (shrink)

: This article contributes to the contemporary debate regarding the young Heidegger’s method of formal indication. Theodore Kisiel argues that this method constitutes a radical break with Husserl---a rejection of phenomenological reflection that paves the way to the non-reflective approach of the Beiträge. Against this view, Steven Crowell argues that formal indication is continuous with Husserlian phenomenology---a refinement of phenomenological reflection that reveals its existential sources. I evaluate this debate and adduce further considerations in favor of Crowell’s view. To do (...) so, I analyze the young Heidegger’s account of phenomenological communication and argue that it further reflects the continuity that Crowell identifies: as he does with reflection, Heidegger refines Husserl’s account of phenomenological communication and sheds light on its existential sources.

In this paper I challenge Merold Westphal’s claim that Jean-Luc Marion’s hermeneutical phenomenology is especially useful for theology. I argue that in spite of his explicit allegiance to Husserl’s “principle of all principles,” Marion fails to embody a commitment to phenomenological seeing in his analyses of revelation. In the sections of Being Given where he discusses revelation, Marion allows faith-based claims to bleed into his phenomenological analyses, resulting in what I call his ‘blurred vision’—the pretension that phenomenological seeing can be (...) extended to theological matters. This pretension undermines Marion’s phenomenological aspirations, because it invests his analyses with a theological content that phenomenological intuition cannot account for or clarify. At the same time, this blurring of the line between theology and phenomenology also makes Marion’s work theologically ineffective. For it furnishes the theologian and believer with the false assurance that faith-based commitments can be grounded in phenomenological knowledge—a claim that he simply cannot make good on. In light of these problems, I propose an alternative Heideggerian approach that maintains the boundary between philosophical and theological discourse and thereby safeguards the integrity of both.

This paper examines the puruṣa concept in the Caraka Saṃhitā, an early text of Ayurveda, and its relation to Indic thinking about phenomenal worldhood. It argues that, contrary to the usual interpretation, early Ayurveda does not consider the person to be a microcosmic replication of the macrocosmos. Instead, early Ayurveda asserts that personhood is worldhood, and thus the person is non-different from the phenomenal totality of his existence. This is confirmed by the CS’s several definitions of puruṣa, which are alternately (...) posed in terms familiar to Vaiśeṣika, early Sāṃkhya, early Buddhism, and Upaniṣadic monism. It is likewise confirmed by the Ayurvedic logic of sāmānya, which governs the meaning of the list of person-to-world correspondences in CS 4.5 and its often misinterpreted claim, puruṣo’yam lokasaṃmitaḥ. Finally it is confirmed in the program of Ayurvedic therapeutics, which aims at establishing various kinds of “appropriateness” for the sake of effecting samayoga—the “harmonious joining” of person and world.

At the same time that social justice concerns are on the rise on college campuses, empathy levels among US college students are falling. Social injustice resulting from organizational decisions and actions causes profound and unnecessary human suffering, and research to understand antecedents to these decisions and actions lacks attention. Empathy represents a potential tool and critical skill for organizational decision-makers, with empirical evidence linking empathy to moral recognition of ethical situations and greater breadth of understanding of stakeholder impact and improved (...) financial success. This study explores the potential relationship between empathy and social justice, using a multifaceted operationalization of social justice, which includes management actions and social sympathies. Results broadly support the positive empathy and social justice relationship and suggest higher education interventions to develop empathy in college business students. (shrink)

One of the most basic functions of human language is to convey who did what to whom. In the world's languages, the order of these three constituents (subject [S], verb [V], and object [O]) is uneven, with SOV and SVO being most common. Recent experiments using experimentally elicited pantomime provide a possible explanation of the prevalence of SOV, but extant explanations for the prevalence of SVO could benefit from further empirical support. Here, we test whether SVO might emerge because (a) (...) SOV is not well suited for describing reversible events (a woman pushing a boy) and (b) pressures to be efficient and mention subjects before objects conspire to rule out many other alternatives. We tested this by asking participants to describe reversible and non‐reversible events in pantomime, and we instructed some participants to be consistent in the form of their gestures and to teach them to the experimenter. These manipulations led to the emergence of SVO in speakers of both English (SVO) and Turkish (SOV). (shrink)

To corroborate the music and social bonding hypothesis, we propose that future investigations isolate specific components of social bonding and consider the influence of context. We deconstruct and operationalize social bonding through the lens of social psychology and provide examples of specific measures that can be used to assess how the link between music and sociality varies by context.

There is growing interest in nature-based interventions to improve human health and wellbeing. An important nascent area is exploring the potential of outdoor therapies to treat and prevent common mental health problems like depression. In this conceptual analysis on the nature–depression nexus, we distil some of the main issues for consideration when NBIs for depression are being developed. We argue that understanding the mechanisms, or ‘active ingredients’ in NBIs is crucial to understand what works and for whom. Successfully identifying modifiable (...) mediating intervention targets will pave the way for interventions with increased efficacy. We highlight a non-exhaustive list of five clinically relevant putative, candidate mechanisms which may underly the beneficial effects of NBIs on depression: stress, rumination, mindfulness, sleep and exercise. We also make the case that when developing NBIs it is important to not neglect young people, explore personalised approaches and focus on both treatment and prevention approaches. To achieve these aims methodologically rigorous programmes of clinical research are needed that include well-powered and controlled experimental designs including randomised controlled trials, qualitative research, longitudinal studies and large prospective cohorts.

We question the generalizability of Glover's model because it fails to distinguish between different forms of planning. The highly controlled experimental situations on which this model is based, do not reflect some important factors that contribute to planning. We discuss several classes of action that seem to imply distinct planning mechanisms, questioning Glover's postulation of a single “planning system.”.

The empirical support for the shared circuits model (SCM) is mixed. We review recent results from our own lab and others supporting a central claim of SCM that mirroring occurs at multiple levels of representation. By contrast, the model is silent as to why human infants are capable of showing imitative behaviours mediated by a mirror system. This limitation is a problem with formal models that address neither the neural correlates nor the behavioural evidence directly.

This volume has 41 chapters written to honor the 100th birthday of Mario Bunge. It celebrates the work of this influential Argentine/Canadian physicist and philosopher. Contributions show the value of Bunge’s science-informed philosophy and his systematic approach to philosophical problems. The chapters explore the exceptionally wide spectrum of Bunge’s contributions to: metaphysics, methodology and philosophy of science, philosophy of mathematics, philosophy of physics, philosophy of psychology, philosophy of social science, philosophy of biology, philosophy of technology, moral philosophy, social and political (...) philosophy, medical philosophy, and education. The contributors include scholars from 16 countries. Bunge combines ontological realism with epistemological fallibilism. He believes that science provides the best and most warranted knowledge of the natural and social world, and that such knowledge is the only sound basis for moral decision making and social and political reform. Bunge argues for the unity of knowledge. In his eyes, science and philosophy constitute a fruitful and necessary partnership. Readers will discover the wisdom of this approach and will gain insight into the utility of cross-disciplinary scholarship. This anthology will appeal to researchers, students, and teachers in philosophy of science, social science, and liberal education programmes. 1. Introduction Section I.

Epistemology has long mesmerized its practitioners with numerous puzzles. What can we know, and how can we know it? In Epistemology: A Contemporary Introduction, Alvin Goldman, one of the most noted contemporary epistemologists, and Matthew McGrath, known for his work on a wide range of topics in the field, have joined forces to delve into these puzzles.

Dance is an enjoyable, non-therapy-focused activity that may provide a range of benefits for people with Parkinson’s. The internal simulation of movement through observation, imitation, and imagery, is intrinsic to dance and may contribute to functional improvements for people with Parkinson’s. This study explored the feasibility and potential benefits of a dance program designed by a collaborative team of dance artists, researchers, physiotherapists, and people living with Parkinson’s. The program incorporated motor simulation through observation, imitation and imagery of movement, supported (...) by creative themes, expression, and music. A 6-week pilot trial of the program was conducted with 10 people with Parkinson’s. A focus group following the trial (N= 8) provided insights into the use of imagery, observation and imitation within dance, and the link between creativity and functional outcomes, as well as indicating multidimensional benefits of dance as reported in previous studies. Exploratory outcome measures also suggested potential effects on motor simulation, functional dexterity, and quality of life. The present study demonstrates the feasibility of a co-developed dance program for Parkinson’s and indicates how creative elements of dance may support functional outcomes. Future research should examine the role of motor simulation processes in dance for Parkinson’s, including the potential to develop transferable cognitive-motor skills. This study also highlights the value of collaborative partnerships in designing dance for health programs, which may optimise beneficial effects by using creative approaches to incorporate evidence-based elements, with guidance from individuals with lived experience to ensure the relevance to their goals.

This paper initiates analytic inquiry into the metaphysics of masculinity. I argue that individual masculinities (such as ‘clone masculinity’ and ‘incel masculinity’) are distinct homeostatic property cluster kinds related to gender structures via processes of adherence, failed-adherence, selective adherence, and/or reinterpretation with respect to male-coded social norms.

The notion that business organizations are akin to Aristotelian political communities has been a central feature of research into virtue ethics in business. In this article, I begin by outlining this “community thesis” and go on to argue that psychological research into the “just world fallacy” presents it with a significant challenge. The just world fallacy undermines our ability to implement an Aristotelian conception of justice, to each as he or she is due, and imperils the relational equality required for (...) shared participation in communities. In the final section, I offer a description of what Aristotelian community might look like within organizations, and some suggestions about how it may be possible to resist the challenge posed by the just world fallacy.

Recent research on the evolution of religion has focused on whether religion is an unselected by-product of evolutionary processes or if it is instead an adaptation by natural selection. Adaptive hypotheses for religion include direct fitness benefits from improved health and indirect fitness benefits mediated by costly signals and/or cultural group selection. Herein, I propose that religious denominations achieve indirect fitness gains for members through the use of ecologically arbitrary beliefs, rituals, and moral rules that function as recognition markers of (...) cultural inheritance analogous to kin and species recognition of genetic inheritance in biology. This recognition signal hypotheses could act in concert with either costly signaling or cultural group selection to produce evolutionarily altruistic behaviors within denominations. Using a cultural phylogenetic analysis, I show that a large set of religious behaviors among extant Christian denominations supports the prediction of the recognition signal hypothesis that characters change more frequently near historical schisms. By incorporating demographic data into the model, I show that more-distinctive denominations, as measured through dissimilar characteristics, appear to be protected from intrusion by nonmembers in mixed-denomination households, and that they may be experiencing greater biological growth of their populations even in the present day.

Shared agency is a distinctive kind of sociality that involves interdependent planning, practical reasoning, and action between participants. Philosophical reflection suggests that agents engage in this form of sociality when a special structure of interrelated psychological attitudes exists between them, a set of attitudes that constitutes a collective intention. I defend a new way to understand collective intention as a combination of individual conditional intentions. Revising an initial statement of the conditional intention account in response to several challenges leads to (...) a specification of the properties these intentions need to have in order to be genuine commitments. I then show how a structure of conditional intentions with these properties settles a collection of agents on engaging in social interactions that display all the features typically associated with shared agency.

Critics of the notion of Necessary Being, and critics of arguments for the existence of God, have often claimed to find flaws in the notion or the arguments, and to find flaws that are due to the presence of concealed tautologies. No theist who recalls the unfortunate of St Anselm and its rejection by St Thomas would dare to claim, his hand on his heart, that tautology has never lurked like a serpent in the garden of natural theology. But the (...) ways in which tautology and talk about God come together on occasion may or may not undermine natural theology in general. I for one am loath to abandon arguments for the existence of God, or give up talk of Necessary Being, since, unlike Professor Findlay, I am unwilling to reverence, much less to worship, a focus imaginarius and I want a real God, or none at all. One of the questions is, of course: does the religious believer want a God who must be too real to be real at all? Another question is: if one can sensibly talk of a God so real as to be Necessary, are there grounds for saying that this possible Necessary Being exists? Between them these questions cover a great part, though by no means all, of the ground of modern discussions on the matter of God. (shrink)

I distinguish two ways of explaining our capacity for ‘transparent’ knowledge of our own present beliefs, perceptions, and intentions: an inferential and a reflective approach. Alex Byrne (2011) has defended an inferential approach, but I argue that this approach faces a basic difficulty, and that a reflective approach avoids the difficulty. I conclude with a brief sketch and defence of a reflective approach to our transparent self-knowledge, and I show how this approach is connected with the thesis that we must (...) distinguish between a kind of self-knowledge that is of oneself as agent and another kind that is of oneself as patient.

Imagine I hold up a Granny Smith apple for all to see. You would thereby gain justified beliefs that it was green, that it was apple, and that it is a Granny Smith apple. Under classical foundationalism, such simple visual beliefs are mediately justified on the basis of reasons concerning your experience. Under dogmatism, some or all of these beliefs are justified immediately by your experience and not by reasons you possess. This paper argues for what I call the looks (...) view of the justification of simple visual beliefs. According to the looks view, such beliefs are mediately justified on the basis of reasons concerning how the relevant things look. Unlike under classical foundationalism, under the looks view as I develop it, these reasons are public. They are public with respect to both their content and possession: with respect to content, they are not about ourselves and our experiences, and with respect to their possession, many people can have the very same looks-related reasons.

A widely cited roadblock to bridging ecological psychology and enactivism is that the former identifies with realism and the latter identifies with constructivism, which critics charge is subjectivist. A pragmatic reading, however, suggests non-mental forms of constructivism that simultaneously fit core tenets of enactivism and ecological realism. After advancing a pragmatic version of enactive constructivism that does not obviate realism, I reinforce the position with an empirical illustration: Physarum polycephalum (a slime mold), a communal unicellular organism that leaves slime trails (...) that form chemical barriers that it avoids in foraging explorations. Here, environmental building and sensorimotor engagement are part of the same process with P. polycephalum coordinating around self-created, affordance-bearing geographies, which nonetheless exist independently in ways described by ecological realists. For ecological psychologists, affordances are values, meaning values are external to the perceiver. I argue that agent-enacted values have the same status and thus do not obviate ecological realism or generate subjectivism. The constructivist-realist debate organizes around the emphasis that enactivists and ecological theorists respectively place on the inner constitution of organisms vs. the structure of environments. Building on alimentary themes introduced in the P. polycephalum example and also in Gibson’s work, I go on to consider how environment, brain, visceral systems, and even bacteria within them enter perceptual loops. This highlights almost unfathomable degrees of mutually modulating internal and external synchronization. It also shows instances in which internal conditions alter worldly configurations and invert values, in Gibson’s sense of the term, albeit without implying subjectivism. My aim is to cut across the somatic focus of enactive constructivism and the external environment-oriented emphasis of ecological realism and show that enactivism can enrich ecological accounts of value.

This paper argues that a class of popular views of collective intention, which I call “quasi-psychologism”, faces a problem explaining common intuitions about collective action. Views in this class hold that collective intentions are realized in or constituted by individual, mental, participatory intentions. I argue that this metaphysical commitment entails persistence conditions that are in tension with a purported obligation to notify co-actors before leaving a collective action attested to by participants in experimental research about the interpersonal normativity of collective (...) action. I then explore the possibilities open to quasi-psychologists for responding to this research. (shrink)

Recent develops in AI technology have led to increasingly sophisticated forms of video manipulation. One such form has been the advent of deepfakes. Deepfakes are AI-generated videos that typically depict people doing and saying things they never did. In this paper, I demonstrate that there is a close structural relationship between deepfakes and more traditional fake barn cases in epistemology. Specifically, I argue that deepfakes generate an analogous degree of epistemic risk to that which is found in traditional cases. Given (...) that barn cases have posed a long-standing challenge for virtue-theoretic accounts of knowledge, I consider whether a similar challenge extends to deepfakes. In doing so, I consider how Duncan Pritchard’s recent anti-risk virtue epistemology meets the challenge. While Pritchard’s account avoids problems in traditional barn cases, I claim that it leads to local scepticism about knowledge from online videos in the case of deepfakes. I end by considering how two alternative virtue-theoretic approaches might vindicate our epistemic dependence on videos in an increasingly digital world. (shrink)

A common objection to divine command meta-ethics is the horrendous deeds objection. Critics object that if DCM is true, anything at all could be right, no matter how abhorrent or horrendous. Defenders of DCM have responded by contending that God is essentially good: God has certain character traits essentially, such as being loving and just. A person with these character traits cannot command just anything. In recent discussions of DCM, this ‘essential goodness response’ has come under fire. Critics of DCM (...) have offered various objections to the essential goodness response. This paper responds to these critics. I examine and refute six such objections: the objection from counterpossibles, the objection from omnipotence, the objection from requirements of justice, the objection from God’s moral grounding power, the objection from evil and indifferent deities, and the epistemological objection. I will maintain that despite all that has been said about the horrendous deeds objection in recent analytic philosophy, the horrendous deeds argument is still a bad argument. (shrink)

Physical activity, and likely the motivation for it, varies throughout the day. The aim of this investigation was to create a short assessment (CRAVE: Cravings for Rest and Volitional Energy Expenditure) to measure motivation states (wants, desires, urges) for physical activity and sedentary behaviors. Five studies were conducted to develop and evaluate the construct validity and reliability of the scale, with 1,035 participants completing the scale a total of 1,697 times. In Study 1, 402 university students completed a questionnaire inquiring (...) about the want or desire to perform behaviors “at the present moment (right now).” Items related to physical activity (e.g., “move my body”) and sedentary behaviors (e.g., “do nothing active”). An exploratory structural equation model (ESEM) revealed that 10 items should be retained, loading onto two factors (5 each for Move and Rest). In Study 2, an independent sample (n= 444) confirmed these results and found that Move and Rest desires were associated with stage-of-change for exercise behavior. In Study 3, 127 community-residing participants completed the CRAVE at 6-month intervals over two years- two times each session. Across-session interclass correlations (ICC) for Move (ICC = 0.72–0.95) and Rest (ICC = 0.69–0.88) were higher than when they were measured across 24-months (Move: ICC = 0.53; Rest: ICC = 0.49), indicating wants/desires have state-like qualities. In Study 4, a maximal treadmill test was completed by 21 university students. The CRAVE was completed immediately pre and post. Move desires decreased 26% and Rest increased 74%. Changes in Move and Rest desires were moderately associated with changes in perceived physical fatigue and energy. In Study 5, 41 university students sat quietly during a 50-min lecture. They completed the CRAVE at 3 time points. Move increased 19.6% and Rest decreased 16.7%. Small correlations were detected between move and both perceived energy and tiredness, but not calmness or tension. In conclusion, the CRAVE scale has good psychometric properties. These data also support tenets of the WANT model of motivation states for movement and rest (Stults-Kolehmainen et al., 2020a). Future studies need to explore how desires to move/rest relate to dynamic changes in physical activity and sedentarism. (shrink)

Many philosophers now see meaning in life as a key evaluative category that stands alongside well-being and moral goodness. Our lives are assessed not only by how well they go for us and how morally good they are, but also by their meaningfulness. In this article, I raise a challenge to this view. Theories of meaning in life closely resemble theories of well-being, and there is a suspicion that the former collapse into the latter. I develop this challenge showing that (...) it is formidable. I then answer it by offering a novel account of what meaning in life is and how it differs from well-being. The account I offer is able to resist the strongest form of the challenge while also having much intuitive appeal. (shrink)

In this paper I respond to Robert Taylor's argument that a Rawlsian framework does not support strong affirmative action programs. The paper makes three main arguments. The first disputes Taylor's claim that strong AA would not be needed in ideal conditions. Private racial discrimination, I suggest, might still exist in such conditions, so strong AA might be needed there. The second challenges Taylor's claims that pure procedural justice constrains Rawlsian nonideal theory. I argue that this rests on a fetishizing of (...) pure procedural justice that is absent from Rawls's work. I also show that a revised formulation of Taylor's concern here also fails. My third argument makes a positive Rawlsian case for strong AA in nonideal conditions that builds on a Taylor concession. Taylor suggests that the goal of nonideal theory is to create a world in which ideal theory can be applied. My argument begins by showing that another permissible goal of Rawlsian nonideal theory is to ameliorate injustice. I then argue that Rawls's contractualist framework supports the strongest forms of AA when category 3 interventions are blocked. (shrink)

Recent philosophical debate about the meaning of knowledge claims has largely centered on the question of whether epistemic claims are plausibly thought to be context sensitive. The default assumption has been that sentences that attribute knowledge or justification have stable truth-conditions across different contexts of utterance, once any non-epistemic context sensitivity has been fixed. The contrary view is the contextualist view that such sentences do not have stable truth-conditions but can vary depending on the context of utterance. This debate manifestly (...) presupposes that the meta-epistemological issue of accounting for the meaning of epistemic claims is to be settled by determining the truth-conditions of these claims. I think this presupposition is undermotivated in light of two observations. First, many epistemologists see epistemic claims as evaluative or normative, in some sense. Second, in the meta- ethical debate most philosophers take alternatives to truth-conditional semantics, such as expressivism, as live options when it comes to evaluative or normative claims. As it turns out, I think expressivism doesn’t provide a plausible account of normative concepts across the board. But considering it as an alternative in the meta-epistemological debate points the way to another alternative to truth-conditional semantics. This is a form of inferentialism. In this paper, I try to motivate a move to epistemic inferentialism by showing how it overcomes worries about expressivism and interacts with plausible ideas about the social function epistemic claims play in our commerce with one another and the word.

There is a difference between the conditions in which one can felicitously assert a ‘must’-claim versus those in which one can use the corresponding non-modal claim. But it is difficult to pin down just what this difference amounts to. And it is even harder to account for this difference, since assertions of 'Must ϕ' and assertions of ϕ alone seem to have the same basic goal: namely, coming to agreement that [[ϕ]] is true. In this paper I take on this (...) puzzle, known as Karttunen’s Problem. I begin by arguing that a ‘must’-claim is felicitous only if there is a shared argument for its prejacent. I then argue that this generalization, which I call Support, can explain the more familiar generalization that ‘must’-claims are felicitous only if the speaker’s evidence for them is in some sense indirect. Finally, I sketch a pragmatic derivation of Support. (shrink)

In this paper, I present two tools that help shed light on deep disagreements and their epistemological consequences. First, I argue that we are best off construing deep disagreements as disagreements over conflicting understandings of certain concepts. More specifically, I suggest that deep disagreements are disagreements over how to understand concepts that play what Michael Friedman calls a “constitutive” role for speakers. Second, I argue that we need a better understanding of what speakers are doing when they engage in deep (...) disagreements—what speech acts they are carrying out. I show that we are best off not reducing the relevant speech acts to more familiar speech act kinds, such as assertions or imperatives. I argue that when a speaker articulates an understanding of a concept, they are in part carrying out an act of stipulation. I provide an account of the pragmatics of stipulation and apply the account to examples of deep disagreement. Focusing on the stipulative dimension of deep disagreement opens up, in turn, a novel approach to defusing the epistemological challenges such disagreement seems to pose. (shrink)

Reductive metaethical views have ethical implications that are frequently inconsistent with our settled ethical intuitions and favored ethical theories. This makes theory choice in metaethics difficult. When we are assessing reductive views, what sort of weight should we accord to their counterintuitive ethical implications? How should we weigh intensional adequacy and explanatory power against apparent extensional inadequacy? I argue that we currently assign too much weight to extensional worries in our metaethical theorizing: We should be willing to tolerate even a (...) great many counterintuitive ethical implications for the sake of a compelling explanation of our ethical practices. Especially when it comes to theorizing about reasons for action, extensional worries should take a back seat to intensional adequacy and explanatory power. My case for this claim beings with a familiar story about the origins of our moral concepts drawn from the work of G. E. M. Anscombe and Alisdair MacIntyre and proceeds via an observation about the nature of practical reasoning. (shrink)

Additive theories of rationality, as I use the term, are theories that hold that an account of our capacity to reflect on perceptually-given reasons for belief and desire-based reasons for action can begin with an account of what it is to perceive and desire, in terms that do not presuppose any connection to the capacity to reflect on reasons, and then can add an account of the capacity for rational reflection, conceived as an independent capacity to ‘monitor’ and ‘regulate’ our (...) believing-on-the-basis-of-perception and our acting-on-the-basis-of-desire. I show that a number of recent discussions of human rationality are committed to an additive approach, and I raise two difficulties for this approach, each analogous to a classic problem for Cartesian dualism. The interaction problem concerns how capacities conceived as intrinsically independent of the power of reason can interact with this power in what is intuitively the right way. The unity problem concerns how an additive theorist can explain a rational subject's entitlement to conceive of the animal whose perceptual and desiderative life he or she oversees as ‘I’ rather than ‘it’. I argue that these difficulties motivate a general skepticism about the additive approach, and I sketch an alternative, ‘transformative’ framework in which to think about the cognitive and practical capacities of a rational animal.
