The evolution of complex life forms, such as multicellular organisms, is the result of a number of evolutionary transitions in individuality (ETIs). Several attempts have been made to explain their origins, many of which have been internalist (i.e., based largely on internal properties of these life form's ancestors). Here, we show how an externalist perspective, via the ecological scaffolding model in which properties of complex life forms arise from an external scaffold, can shed new light on the question of ETIs. (...) Ultimately, we anticipate progress in the field will occur by recognizing the importance of both the internalist and externalist modes of explanation for ETIs. We illustrate this by considering an extension of the ecological scaffolding model by niche construction in which particles modify the environment which later becomes the scaffold giving rise to collective-level individuality.

Contemporary philosophers of mind tend to assume that the world of nature can be reduced to basic physics. Yet there are features of the mind consciousness, intentionality, normativity that do not seem to be reducible to physics or neuroscience. This explanatory gap between mind and brain has thus been a major cause of concern in recent philosophy of mind. Reductionists hold that, despite all appearances, the mind can be reduced to the brain. Eliminativists hold that it cannot, and that this (...) implies that there is something illegitimate about the mentalistic vocabulary. Dualists hold that the mental is irreducible, and that this implies either a substance or a property dualism. Mysterian non-reductive physicalists hold that the mind is uniquely irreducible, perhaps due to some limitation of our self-understanding. In this book, Steven Horst argues that this whole conversation is based on assumptions left over from an outdated philosophy of science. While reductionism was part of the philosophical orthodoxy fifty years ago, it has been decisively rejected by philosophers of science over the past thirty years, and for good reason. True reductions are in fact exceedingly rare in the sciences, and the conviction that they were there to be found was an artifact of armchair assumptions of 17th century Rationalists and 20th century Logical Empiricists. The explanatory gaps between mind and brain are far from unique. In fact, in the sciences it is gaps all the way down.And if reductions are rare in even the physical sciences, there is little reason to expect them in the case of psychology. Horst argues that this calls for a complete re-thinking of the contemporary problematic in philosophy of mind. Reductionism, dualism, eliminativism and non-reductive materialism are each severely compromised by post-reductionist philosophy of science, and philosophy of mind is in need of a new paradigm. Horst suggests that such a paradigm might be found in Cognitive Pluralism: the view that human cognitive architecture constrains us to understand the world through a plurality of partial, idealized, and pragmatically-constrained models, each employing a particular representational system optimized for its own problem domain. Such an architecture can explain the disunities of knowledge, and is plausible on evolutionary grounds. (shrink)

In this carefully argued critique, Steven Horst pronounces the theory deficient.

Horst Bredekamp’s subject is the astute deployment and perennial resonance of the startling image of the body politic that dominates the frontispiece to Leviathan: a treatise on the psychology of the individual and the dynamic of the multitude, published in 1651 by the English philosopher Thomas Hobbes. Affirming the centrality of such a figural device for this pioneering theorist of the state, Bredekamp goes on to address the art-historical dimension of the mesmerising etched title-page. In his central chapters he (...) explores the extraordinary range of sources – from socio-cultural tradition to scientific advances – on which the author and his artist-collaborator may have drawn. In conclusion, he reveals Hobbes to be no less passionate than shrewd in his belief that the constraints and amenities of a tolerable life in common attest to the potency of the visual. As appendices, two essays and catalogues explore the portraits made of Hobbes as well as illustrations that appeared in his other works, thus systematically completing the exploration of the images connected with this exceptional philosopher.

Epistemic constitutivism (EC) holds that the nature of believing is such that it gives rise to a standard of correctness and that other epistemic normative notions (e.g., reasons for belief) can be explained in terms of this standard. If defensible, this view promises an attractive and unifying account of epistemic normativity. However, EC faces a forceful objection: that constitutive standards of correctness are never enough for generating normative reasons. This paper aims to defend EC in the face of this objection. (...) I do so in two steps. First, I dispute a crucial assumption underlying the case against EC: that constitutive standards of correctness in general are ‘reason-giving’ only if and because there is also a prior reason to comply with them. Second, I outline a strategy of how EC can meet the challenge of explaining what’s special about the activity of believing such that, unlike other standard-governed activities, it is capable of generating normative reasons.

Many virtue epistemologists conceive of epistemic competence on the model of skill —such as archery, playing baseball, or chess. In this paper, I argue that this is a mistake: epistemic competences and skills are crucially and relevantly different kinds of capacities. This, I suggest, undermines the popular attempt to understand epistemic normativity as a mere special case of the sort of normativity familiar from skilful action. In fact, as I argue further, epistemic competences resemble virtues rather than skills—a claim that (...) is based on an important, but often overlooked, difference between virtue and skill. The upshot is that virtue epistemology should indeed be based on virtue, not on skill. (shrink)

This book introduces an account of cognitive architecture, Cognitive Pluralism, on which the basic units of understanding are models of particular content domains. Having many mental models is a good adaptive strategy for cognition, but models can be incompatible with one another, leading to paradoxes and inconsistencies of belief, and it may not be possible to integrate the understanding supplied by multiple models into a comprehensive and self-consistent "super model". The book applies the theory to explaining intuitive reasoning and cognitive (...) illusions and explores implications for epistemology, semantics, and disunity of science. (shrink)

Someone acts in a morally worthy way when they deserve credit for doing the morally right thing. But when and why do agents deserve credit for the success involved in doing the right thing? It is tempting to seek an answer to that question by drawing an analogy with creditworthy success in other domains of human agency, especially in sports, arts, and crafts. Accordingly, some authors have recently argued that, just like creditworthy success in, say, chess, playing the piano, or (...) archery, creditworthy moral success is a matter of getting things right by way of manifesting a relevant skill. My main aim in this paper is to bring out an important structural difference between moral creditworthiness and creditworthiness in sports, arts, and craft, undermining attempts to use examples of the latter as a model for understanding the former. As an alternative, I propose an account of morally creditworthy action, according to which such action is a matter of manifesting virtue, not skill—a claim that's based on an important, but underappreciated, difference between the sorts of excellences constituting virtues and skills. The paper thus contributes to a more nuanced picture of normative achievements across different domains of human agency, highlighting largely overlooked structural dissimilarities among them.

Many hold that theoretical reasoning aims at truth. In this paper, I ask what it is for reasoning to be thus aim-directed. Standard answers to this question explain reasoning’s aim-directedness in terms of intentions, dispositions, or rule-following. I argue that, while these views contain important insights, they are not satisfactory. As an alternative, I introduce and defend a novel account: reasoning aims at truth in virtue of being the exercise of a distinctive kind of cognitive power, one that, unlike ordinary (...) dispositions, is capable of fully explaining its own exercises. I argue that this account is able to avoid the difficulties plaguing standard accounts of the relevant sort of mental teleology. (shrink)

This paper provides an analysis of U.S. farmland owners, operators, and workers by race, ethnicity, and gender. We first review the intersection between racialized and gendered capitalism and farmland ownership and farming in the United States. Then we analyze data from the 2014 Tenure and Ownership Agricultural Land survey, the 2012 Census of Agriculture, and the 2013–2014 National Agricultural Worker Survey to demonstrate that significant nation-wide disparities in farming by race, ethnicity and gender persist in the U.S. In 2012–2014, White (...) people owned 98% and operated 94% of all farmland. They generated 98% of all farm-related income from land ownership and 97% of income from farm owner-operatorship. Meanwhile, People of Color farmers were more likely to be tenants rather than owners, owned less land, and generated less farm-related wealth per person than their White counterparts. Hispanic farmers were also disproportionately farm laborers. In addition to racial and ethnic disparities, there were disparities by gender. About 63% of non-operating landowners, 86% of farm operators, and 87% of tenant farmers were male, and female farmers tended to generate less income per farmer than men. This data provides evidence of ongoing racial, ethnic and gender disparities in agriculture in the United States. We conclude with a call to address the structural drivers of the disparities and with recommendations for better data collection. (shrink)

This book challenges the standard view that modern hermeneutics begins with Friedrich Ast and Friedrich Schleiermacher, arguing instead that it is the dialectic of reflective and teleological reason in Kant’s Critique of Judgment that provides the actual proto-hermeneutic foundation. It is revolutionary in doing so by replacing interpretive truth claims by the more appropriate claim of rendering opaque contexts intelligible. Taking Gadamer’s comprehensive analysis of hermeneutics in Truth and Method (1960) as its point of departure, the book turns to Kant’s (...) Critiques, reviewing his major concepts as a coherent system in relation to his sensus communis. At the heart of the book is the interaction between reflective, bottom-up search and teleological, top-down interpretative projection as provided in Part II of the third Critique. This text contends that Kant’s broad definition of nature invites the liberation of the reflective-teleological judgment from its biological exemplifications and so permits us to establish its generalised status as a path-breaking, methodological tool. Kant’s dialectic of reflective search and meaning bestowing, stipulated teleology is asserted to anticipate a series of motifs commonly associated with hermeneutics. Figures covered include Dilthey, Husserl, Ingarden, Heidegger, Gadamer, Apel, Habermas, Ricoeur, Derrida, Foucault, Lyotard, Deleuze, Vattimo, Nancy and Caputo. Their collective contributions to interpretation allow for a review of the evolution of hermeneutics from the perspective of the Kantian critique of the limitations of human cognition. The book is written for the informed, general reader, but will likewise appeal to advanced undergraduate and graduate students as well as researchers in the humanities and social sciences. (shrink)

Towards the end of Beyond Reduction Horst hypothesizes that ‘it is a general design principle of the cognitive architecture of humans that the mind possesses multiple models for understanding and interacting practically with different aspects of the world’. The suggestion is made following a discussion of recent research in cognitive science. According to Horst, the hypothesis is also consistent with what recent non-reductionist tendencies in the philosophy of science teach us. Taken together, Horst claims these two sets (...) of evidence motivate a new post-reductionist approach to the philosophy of mind. After outlining the route Horst takes to reach this claim, I shall raise a worry I have about the claim and the route taken to it.Beyond Reduction is in three parts. Part one frames the debate. In Chapter 1 Horst notes how naturalism is a view to which nearly all philosophers of mind, some of whom hold quite disparate views, would subscribe. He formulates a schema for naturalism that he thinks most would accept: ‘naturalism about domain D is the view that all features of D are to be accommodated within the framework of nature as it is understood by the natural sciences’. Horst acknowledges that the schema under-describes matters. The notion of ‘accommodation’ may be understood as involving either explanation or metaphysical determination; it is also unclear how we are to understand ‘the …. (shrink)

Seit dem byzantinischen Bilderstreit und dem Bildersturm der Reformation ist nicht mehr in solcher Intensität über Bilder nachgedacht worden wie in den letzten Jahrzehnten. Neben der Archäologie und der Kunstgeschichte haben sich zahlreiche weitere Fächer an Fragestellungen rund um das Bild geradezu festgebissen. Angesichts dessen geht einer der bedeutendsten Kunsthistoriker der Gegenwart der Frage nach, warum Begriff und Geltung sowie Macht und Ohnmacht von Bildern so hartnäckig verfolgte Themen unserer Tage geworden sind.

Since the seventeenth century, our understanding of the natural world has been one of phenomena that behave in accordance with natural laws. While other elements of the early modern scientific worldview may be rejected or at least held in question—the metaphor of the world as a great machine, the narrowly mechanist assumption that all physical interactions must be contact interactions, the idea that matter might actually be obeying rules laid down by its Divine Author – the notion of natural law (...) has continued to play a pivotal role in actual scientific practice, in our philosophical interpretations of science, and in their its metaphysical implications.

Over the past several decades, the philosophical community has witnessed the emergence of an important new paradigm for understanding the mind.1 The paradigm is that of machine computation, and its influence has been felt not only in philosophy, but also in all of the empirical disciplines devoted to the study of cognition. Of the several strategies for applying the resources provided by computer and cognitive science to the philosophy of mind, the one that has gained the most attention from philosophers (...) has been the Computational Theory of Mind (CTM). CTM was first articulated by Hilary Putnam (1960, 1961), but finds perhaps its most consistent and enduring advocate in Jerry Fodor (1975, 1980, 1981, 1987, 1990, 1994). It is this theory, and not any broader interpretations of what it would be for the mind to be a computer, that I wish to address in this paper. What I shall argue here is that the notion of symbolic representation employed by CTM is fundamentally unsuited to providing an explanation of the intentionality of mental states (a major goal of CTM), and that this result undercuts a second major goal of CTM, sometimes refered to as the vindication of intentional psychology. This line of argument is related to the discussions of derived intentionality by Searle (1980, 1983, 1984) and Sayre (1986, 1987). But whereas those discussions seem to be concerned with the causal dependence of familiar sorts of symbolic representation upon meaning-bestowing acts, my claim is rather that there is not one but several notions of meaning to be had, and that the notions that are applicable to symbols are conceptually dependent upon the notion that is applicable to mental states in the fashion that Aristotle refered to as paronymy. That is, an analysis of the notions of meaning applicable to symbols reveals that they contain presuppositions about meaningful mental states, much as Aristotle's analysis of the sense of healthy that is applied to foods reveals that it means conducive to having a healthy body, and hence any attempt to explain mental semantics in terms of the semantics of symbols is doomed to circularity and regress. I shall argue, however, that this does not have the consequence that computationalism is bankrupt as a paradigm for cognitive science, as it is possible to reconstruct CTM in a fashion that avoids these difficulties and makes it a viable research framework for psychology, albeit at the cost of losing its claims to explain intentionality and to vindicate intentional psychology. I have argued elsewhere (Horst, 1996) that local special sciences such as psychology do not require vindication in the form of demonstrating their reducibility to more fundamental theories, and hence failure to make good on these philosophical promises need not compromise the broad range of work in empirical cognitive science motivated by the computer paradigm in ways that do not depend on these problematic treatments of symbols.

Over the past thirty years, it is been common to hear the mind likened to a digital computer. This essay is concerned with a particular philosophical view that holds that the mind literally is a digital computer (in a specific sense of “computer” to be developed), and that thought literally is a kind of computation. This view—which will be called the “Computational Theory of Mind” (CTM)—is thus to be distinguished from other and broader attempts to connect the mind with computation, (...) including (a) various enterprises at modeling features of the mind using computational modeling techniques, and (b) employing some feature or features of production-model computers (such as the stored program concept, or the distinction between hardware and software) merely as a guiding metaphor for understanding some feature of the mind. This entry is therefore concerned solely with the Computational Theory of Mind (CTM) proposed by Hilary Putnam [1961] and developed most notably for philosophers by Jerry Fodor [1975, 1980, 1987, 1993]. The senses of ‘computer’ and ‘computation’ employed here are technical; the main tasks of this entry will therefore be to elucidate: (a) the technical sense of ‘computation’ that is at issue, (b) the ways in which it is claimed to be applicable to the mind, (c) the philosophical problems this understanding of the mind is claimed to solve, and (d) the major criticisms that have accrued to this view.

In acting intentionally, it is no accident that one is doing what one intends to do. In this paper, I ask how to account for this non-accidentality requirement on intentional action. I argue that, for systematic reasons, the currently prevailing view of intentional action – the Causal Theory of Action – is ill-equipped to account for it. I end by proposing an alternative account, according to which an intention is a special kind of cause, one to which it is essential (...) that it represents its effect. (shrink)

Shaping the Future maps out the ascetic practices of a Neitzschean way of life. Hutter argues that Nietzsche's doctrines are attempts and "temptations" that aim to provoke his free-spirited readers into changing themselves by putting philosophy into practice in their lives.

Digital data is an increasing and continual presence across the sites, activities and relationships of everyday life. In this article we explore what data presence means for the ways that the everyday is organised, sensed, and anticipated. While digital data studies have demonstrated how data is deeply entangled with the way in which everyday life is lived out and valued, at the same time our relationships with data are riddled with anxieties or small niggles or tricky trade-offs and their use (...) is often chaotic and muddled, part of the inevitable uncertainty about what will happen next. If the presence of data is part of the environments we inhabit, this raises the question of how and why data is valuable to us and what forms of hope and trust enable this value to further develop.

In this book, I offer an account of intentional action. The book has two main parts: in the first part, I discuss and criticize the currently prevailing account of intentional action—the Causal Theory of Action (CTA)—and, in the second part, I offer my alternative account. The CTA proposes essentially two conditions for something that you do to be an intentional action: (1) what you do is represented by your intention (or other mental attitudes), and (2) it is caused by your (...) intention. Against the CTA, I argue that, since it conceives of representation and causality as essentially separate conditions, it cannot explain why, when someone acts intentionally, it is not a mere accident that both conditions are jointly satisfied: i.e., that the intention causes the movement it represents. The CTA’s inability to rule out such accidentality is, as I argue further, the deeper source of the notorious problem of deviant causation. Given this diagnosis, I claim that the key for a satisfactory account of intentional action is to conceive of the essential unity of representation and causality in intentional action. Doing so, I suggest, requires understanding a distinctive sort of causality at work in intentional action. Following the work of G.E.M. Anscombe, I argue that what is distinctive of the sort of causal-explanatory connection captured in action explanations like “S is doing A because she intends to do B” is that it is essentially known by the acting subject. In the final sections of the book, I then develop and defend a conception of the sort of self-knowledge involved in intentional action. (shrink)

Von Natur aus ist der Mensch so frei wie wölfisch. Um sich selbst zu bändigen, muß er folglich einen künstlichen Riesen schaffen, den Staat, der als übergeordnete Instanz den permanenten Bürgerkrieg zu unterdrücken und Frieden zu schaffen vermag. Diese Essenz von Thomas Hobbes'"Leviathan" ist bis heute ebenso vehement verworfen wie bekräftigt worden. In den letzten Jahrzehnten wurden vor allem die historischen Bedingungen erschlossen, unter denen Hobbes sein epochales Werk verfaßte; aber seine bestürzende Grundthese, daß es des Schreckens bedarf, um inneren (...) Frieden zu erzeugen, ist eine Herausforderung für jedwede Staats- und Gesellschaftstheorie geblieben. Zu den Mitteln, mit denen der Leviathan die Menschen vom Unfrieden abhält, gehören Bilder, und aus diesem Grund steht dem Leviathan ein Frontispiz voran. Obwohl seit Jahrhunderten selbst entfernteste Aspekte von Hobbes' Werk ausgeleuchtet wurden, ist dieses grundlegende Element seiner Lehre bislang nicht erörtert worden. Eine systematische Untersuchung seiner Wertschätzung des Augensinnes fehlt ebenso wie eine umfassende Analyse seiner Bildmittel. Horst Bredekamp erschließt mit Abraham Bosse den Künstler des Frontispizes, stellt sämtliche Varianten dieses Urbildes des modernen Staates zusammen und versucht, die Vorgeschichte seiner politischen Ikonographie zu klären. Im Zentrum stehen die königlichen Kunstleiber von Westminster Abbey sowie optische Geräte, mit deren Hilfe Hobbes neben dem Körper und dem Raum auch eine künstliche Zeit als Wirkmittel des Leviathan zu etablieren suchte. Gegen Ende seiner prägnanten Analyse erörtert der Autor die Wiederkehr der Hobbesschen Staatsikone im neunzehnten und zwanzigsten Jahrhundert sowie die Zukunft des Staates als Bild. (shrink)

The article combines a criticism of public understanding of science with the sociology of expectations to examine how particular expectations toward scientific progress have performative effects for the construction of publics as citizens of science. By analyzing a particular controversy about gene therapy in Denmark, the article demonstrates how different sets of expectations can be used to discriminate among three different assemblages: the assemblage of consumption, the assemblage of comportment, and the assemblage of heroic action. Each of these assemblages makes (...) medical science, scientific citizenship, politics, patients, doctors, and expectations toward the future emerge in particular ways. By their radically different expectations toward science and their different constructions of what it means to be a scientific citizen, the assemblages construct the objectives of the governance of science in three very different ways.

Most contemporary philosophers of mind claim to be in search of a 'naturalistic' theory. However, when we look more closely, we find that there are a number of different and even conflicting ideas of what would count as a 'naturalization' of the mind. This article attempts to show what various naturalistic philosophies of mind have in common, and also how they differ from one another. Additionally, it explores the differences between naturalistic philosophies of mind and naturalisms found in ethics, epistemology, (...) and philosophy of science. Section 1 introduces a distinction between two types of project that have been styled 'naturalistic', which I call philosophical naturalism and empirical naturalism . Sections 2 to 6 canvass different strands of philosophical naturalism concerning the mind, followed by a much briefer discussion of attempts to provide empirical naturalizations of the mind in Section 7 . Section 8 concludes the essay with a consideration of the relations between philosophical and empirical naturalism in philosophy of mind, arguing that at least some types of philosophical naturalism are incompatible with empirical naturalism.

Recent philosophy of mind has tended to treat.

In lieu of an abstract, here is a brief excerpt of the content:THE CONCEPT OF PERSON IN ST. THOMAS AQUINAS: A Contribution to Recent Discussion* ST. THOMAS AQUINAS accepted and consistently defended Boethius' definition of person: "persona est substantia individua rationalis naturae." St. Thomas' analysis of this definition necessarily involves metaphysical questions because of the implications of the terms " substance" and " nature" and moreover it manifests the inescapahle imprint of the theological problematics which surrounded the issue (e.g. the (...) Trinity and the hypostatic union). Both of these influences, metaphysical and theological, have engendered problems of interpretation and criticism. Contemporary discussions of person largely either continue the scholastic controversies or adopt a modern perspective from which to expose apparent contradictions in St. Thomas' doctrine. The purpose of this article will be limited to a consideration of the metaphysical problems concerning the relationship between individual substance, universal, nature, and existence. It is hoped that such a clarification will resolve not only the neoscholastic controversies, but also some of the contemporary problems. I. BOETHIUS' DEFINITION OF PERSON AND ST.

The first and broadest definition, embracing both substances and accidents, describes nature as belonging to all things which by their being can be in some way or another be comprehended by reason: "natura est earum rermn quae, cum sint, quoquo modo intellectu capi possunt." A second definition, comprising substances alone both corporeal and incorporeal, describes nature as anything that can effect or suffer something: " natura est vel quod facere vel quod pati possit." A third sense, taken from the Aristotelian analysis of the motion of natural substances, describes nature as the immanent principle of movement : "natura est motus principium per se et non per accidens." Finally, nature can also refer to the formal cause which provides the specific difference: " natura est unam quamque rem informans specifica differentia" (cf. ST Ia. 29, I ad 4). It is this last sense which is most important. In sum, "nature" is a broad term encompassing both composite beings and their causes. Boethius continues in chapter two by first narrowing the relevant sense of nature to substances (thus excluding accidents ) and then presenting a complete division of substances. The major distinction is between corporeal substances and incorporeal substances. Corporeal subdivides further into inanimate and animate, with animate dividing. into insensitive and sensitive and the latter dividing finally into irrational and rational. Incorporeal subdivides into rational and irrational (the life-principle of animals), with rational incorporeal substances being further distinguished into those that are immutable by nature (the Creator) and those that are not so by nature (the human soul and angels) but may become so by virtue of the immutable substance. Boethius then argues that person cannot be affirmed of inanimate beings or irrational animals.

THOMAS AQUINAS 437 final distinction of :substance into universal and particular leads to the conclusion that person must refer to an individual. Thus the background is set for the definition of person which opens the third chapter: " naturae rationalis individua substantia." Person must be an individual substance of a certain nature, namely rational, which nature accounts for the form or specific difference of the particular substance (the fourth meaning of chapter 1). The connection of this definition with Aristotle 's definition of man as a rational animal is unmistakable. It should also be noted that this definition of person is applicable not only to man, in whom the rational nature is not identical with his substance, but also to the... (shrink)
