El estudio se propone el análisis de la última de las parábolas del evangelio de Mateo, examinando su lenguaje y elementos teológicos fundamentales; así como también su forma y composición en la obra. El trabajo se motiva por la designación que el Papa Francisco dio al texto, comprendiéndolo como recapitulación esencial del camino cristiano fundamental que debe emprender el discípulo que desea vivir las huellas del Maestro.

En el presente artículo se presenta una reconstrucción del episodio histórico de la cristalización del _management_ industrial a través de la introducción de la Teoría de la Dinámica de Sistemas de Jay Wright Forrester de la Sloan School of Management del MIT. Para ello, se utilizarán explícitamente las herramientas historiográficas provistos por el marco metateórico de Thomas Kuhn, por considerarlo de gran fertilidad para dar cuenta de los episodios de maduración de disciplinas científicas.

In the present work we will search for a refinement of some key epistemological perspectives for the construction of a methodological framework in the social systems simulations area. So, we will proceed to show the origin of some issues in the existent conceptualization and its path through the information sciences as a precedent. There we will identify the consequences of such issues and will work in enlightening the conflictive notions in order to defend an epistemological pluralism which would result beneficial (...) for this area.

Both traditional accounts of hope and some of their recent critics analyze hope exclusively in terms of attitudes that a hoper bears towards a hoped-for prospect, such as desire and probability assignment. I argue that all of these accounts misidentify cases of despair as cases of hope, and so misconstrue the nature of hope. I show that a more satisfactory view is arrived at by noticing that in addition to the aforementioned attitudes, hope involves a characteristic attitude towards an external (...) factor, on whose operation the hoper takes the prospect's realization to depend causally.

Our knowledge about the world is often expressed by generic sentences, yet their meanings are far from clear. This book provides answers to central problems concerning generics: what do they mean? Which factors affect their interpretation? How can one reason with generics? Cohen proposes that the meanings of generics are probability judgments, and shows how this view accounts for many of their puzzling properties, including lawlikeness. Generics are evaluated with respect to alternatives. Cohen argues that alternatives are induced by the (...) kind as well as by the predicated property, and thus provides a uniform account of the varied interpretations of generics. He studies the formal properties of alternatives and provides a compositional account of their derivation by focus and presupposition. Cohen uses his semantics of generics to provide a formal characterization of adequate default reasoning, and proves some desirable results of this formalism. (shrink)

Cognitive penetration of perception, broadly understood, is the influence that the cognitive system has on a perceptual system. The paper shows a form of cognitive penetration in the visual system which I call ‘architectural’. Architectural cognitive penetration is the process whereby the behaviour or the structure of the perceptual system is influenced by the cognitive system, which consequently may have an impact on the content of the perceptual experience. I scrutinize a study in perceptual learning that provides empirical evidence that (...) cognitive influences in the visual system produce neural reorganization in the primary visual cortex. The type of cognitive penetration can be synchronic and diachronic. (shrink)

Arising out of the author's lifetime fascination with the links between the formal language of mathematical models and natural language, this short book comprises five essays investigating both the economics of language and the language of economics. Ariel Rubinstein touches the structure imposed on binary relations in daily language, the evolutionary development of the meaning of words, game-theoretical considerations of pragmatics, the language of economic agents and the rhetoric of game theory. These short essays are full of challenging ideas (...) for social scientists that should help to encourage a fundamental rethinking of many of the underlying assumptions in economic theory and game theory. As a postscript two economists, Tilman Borgers and Bart Lipman, and a logician, Johan van Benthem offer comments. (shrink)

Taxa and homologues can in our view be construed both as kinds and as individuals. However, the conceptualization of taxa as natural kinds in the sense of homeostatic property cluster kinds has been criticized by some systematists, as it seems that even such kinds cannot evolve due to their being homeostatic. We reply by arguing that the treatment of transformational and taxic homologies, respectively, as dynamic and static aspects of the same homeostatic property cluster kind represents a good perspective for (...) supporting the conceptualization of taxa as kinds. The focus on a phenomenon of homology based on causal processes (e.g., connectivity, activity-function, genetics, inheritance, and modularity) and implying relationship with modification yields a notion of natural kinds conforming to the phylogenetic-evolutionary framework. Nevertheless, homeostatic property cluster kinds in taxonomic and evolutionary practice must be rooted in the primacy of epistemological classification (homology as observational properties) over metaphysical generalization (series of transformation and common ancestry as unobservational processes). The perspective of individuating characters exclusively by historical-transformational independence instead of their developmental, structural, and functional independence fails to yield a sufficient practical interplay between theory and observation. Purely ontological and ostensional perspectives in evolution and phylogeny (e.g., an ideographic character concept and PhyloCode’s ‘individualism’ of clades) may be pragmatically contested in the case of urgent issues in biodiversity research, conservation, and systematics.

Philosophy and Phenomenological Research, EarlyView.

This paper presents the foundation upon which the contemporary knowledge of body integrity dysphoria (BID) is built. According to the World Health Organisation’s International Classification of Diseases, 11th edition (ICD-11), the main feature of BID is an intense and persistent desire to become physically disabled in a significant way. Three putative aetiologies that are considered to explain the insurgence of the condition are discussed: neurological, psychological and postmodern theories. The concept of bodily representation within the medical context is highlighted, with (...) the concept of dysphoria, which was brought to the fore with the introduction of the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5), and the ICD-11. Contemporary issues of “justice” are addressed to identify ethically relevant distinctions between BID and sex reassignment surgery. It is argued that there is no ethically relevant difference between the BID actor’s desire for invasive surgical intervention and the wish of gender dysphoric individuals to undergo sex reassignment surgery procedures. Some BID actors self-mutilate, and this presents medical professionals with difficult choices regarding whether or not to intervene in order to satisfy the BID patient’s desire. Both abstention and intervention may lead to severe ethical complications for doctors and patients despite the positive outcomes in terms of quality of life for BID individuals who manage to undergo such procedures.

Generics and frequency statements are puzzling phenomena: they are lawlike, yet contingent. They may be true even in the absence of any supporting instances, and extending the size of their domain does not change their truth conditions. Generics and frequency statements are parametric on time, but not on possible worlds; they cannot be applied to temporary generalizations, and yet are contingent. These constructions require a regular distribution of events along the time axis. Truth judgments of generics vary considerably across speakers, (...) whereas truth judgments of frequency statements are much more uniform. A generic may be false even if the vast majority of individuals in its domain satisfy the predicated property, whereas a frequency statement using, e.g., usually would be true. This paper argues that all these seemingly unrelated puzzles have a single underlying cause: generics and frequency statements express probability judgments, and these, in turn, are interpreted as statements of hypothetical relative frequency.

Generics are sentences such as Birds fly, which express generalizations. They are prevalent in speech, and as far as is known, no human language lacks generics. Yet, it is very far from clear what they mean. After all, not all birds fly—penguins don’t! -/- There are two general views about the meaning of generics in the literature, and each view encompasses many specific theories. According to the inductivist view, a generic states that a sufficient number of individuals satisfy a certain (...) property—in the example above, it says that sufficiently many birds fly. This view faces the complicated problem of spelling out exactly how many is “sufficiently many” in a way that correctly captures the intuitive truth conditions of generics. -/- An alternative, the rules and regulations view, despairs from this project and proposes instead that generics directly express rules in the world. Rules are taken to be abstract objects, which are not related to the properties of specific individuals. This view faces the difficult problem of explaining how people come to know of such rules when judging the truth of falsity of generics, and accounting for the strong intuition that a sentence such as Birds fly talks about birds, not abstract objects. -/- What seems to be beyond dispute is that generics, even if they do not express rules, are lawlike: they state non-accidental generalizations. Many scholars have taken this fact to indicate that generics are parametric on possible worlds: they refer to worlds other than the actual world. This, again, raises the problem of how people come to know about what happens in these other worlds. However, a rigorous application of standard tests for intensionality shows that generics are not, in fact, parametric on possible worlds, but only on time. This unusual property may explain much of the mystery surrounding generics. -/- Another mysterious property of generics is that although there is no language without them, there is no linguistic construction that is devoted to the expression of genericity. Rather, generics can be expressed in a variety of ways, each of which can also express nongenerics. Yet, each manifestation of generics differs subtly (or sometimes not so subtly) in its meaning from the others. -/- Even when these and other puzzles of genericity are solved, one mystery would remain: Why are generics, which are so easy to produce and understand in conversation, so difficult to analyze?

ABSTRACTThis article argues that received accounts of the concept of human dignity face more difficulties than has been appreciated, when explaining the connection between human dignity and the duty of respect that dignity is supposed to generate. It also argues that a novel, relational, account has the adequate structure to explain such connection.

I offer a feminist critique of deep ecology as presented in the seminal papers of Naess and Devall. I outline the fundamental premises involved and analyze their internal coherence. Not only are there problems on logical grounds, but the tacit methodological approach of the two papers are inconsistent with the deep ecologists’ own substantive comments. I discuss these shortcomings in terms of a broader feminist critique of patriarchal culture and point out some practical and theoretical contributions which eco-feminism can make (...) to a genuinely deep ecology problematic.

In this paper we discuss Ned Hall's critique of David Lewis's counterfactual theory of causation, in particular for its alleged inability to account for cases of double prevention. To do so, we focus on Pablo Melogno's response to Hall, where he claims that Hall's proposed tension between the concept of dependence and the locality thesis in cases of double prevention is the effect of the omission of essential details to complete the causal chain in the examples used by Hall. Here (...) we propose to take a further step in the defense of the counterfactual theory begun by Melogno, by reviewing the examples proposed by Hall, the modifications complexified by Melogno and the corollaries that follow from them, and proposing some relevant conceptual extensions to the ideas of the three authors.

It is widely agreed that generics tolerate exceptions. It turns out, however, that exceptions are tolerated only so long as they do not violate homogeneity: when the exceptions are not concentrated in a salient “chunk” of the domain of the generic. The criterion for salience of a chunk is cognitive: it is dependent on the way in which the domain is mentally represented. Findings of psychological experiments about the ways in which different domains are represented, and the actors affecting such (...) representations, account for judgments of generic sentences, facts which cannot be explained by linguistics alone. The reason for the homogeneity requirement itself is, in turn, also dependent on cognitive considerations. Generics express default rules, and psychological findings have shown that, the more homogeneous the domain, the easier it is for subjects to infer rules about it. Thus, cognitive results form a crucial part of a comprehensive account of the meaning of a linguistic expression. (shrink)

En este trabajo nos enfocamos fundamentalmente en responder dos interrogantes: (a) ¿Pueden las mujeres ser sujetos ilustrados desde la perspectiva de Hume? y en caso de responder afirmativamente, (b) ¿resulta esta ilustración emancipatoria en términos feministas? En primer lugar, reconstruimos las principales líneas de interpretación feministas de la obra de Hume para ubicar nuestra propuesta dentro de una corriente interpretativa poco explorada aún. En segundo lugar, precisamos el sentido que puede adoptar la noción de “ilustración” en la filosofía de Hume, (...) en discusión con debates de la literatura secundaria contemporánea. En tercer lugar, orientamos nuestra reflexión a responder el primero de los interrogantes e indagamos si las mujeres están incluidas dentro de los rasgos ilustrados que podemos reconocer en el pensamiento de Hume y en qué condiciones. En cuarto y último lugar, ensayamos una respuesta al segundo interrogante: si aquello que podemos interpretar como ilustración femenina en clave humeana constituye una vía para la emancipación de la dominación patriarcal o si, por el contrario, refuerza el sometimiento de las mujeres.

In this paper, we present a way to translate the metainferences of a mixed metainferential system into formulae of an extended-language system, called its associated σ-system. To do this, the σ-system will contain new operators (one for each standard), called the σ operators, which represent the notions of "belonging to a (given) standard". We first prove, in a model-theoretic way, that these translations preserve (in)validity. That is, that a metainference is valid in the base system if and only if its (...) translation is a tautology of its corresponding σ-system. We then use these results to obtain other key advantages. Most interestingly, we provide a recipe for building unlabeled sequent calculi for σ-systems. We then exemplify this with a σ-system useful for logics of the ST family, and prove soundness and completeness for it, which indirectly gives us a calculus for the metainferences of all those mixed systems. Finally, we respond to some possible objections and show how our σ-framework can shed light on the “obeying” discussion within mixed metainferential contexts. (shrink)

Character education is an increasingly discussed topic drawing upon virtue ethics as a moral theory. Scholars have predominantly understood educating character as a process that entails the formation of certain distinct character traits or functions through practice and habituation. However, these approaches present some problems. This paper explores the educational implications of various accounts focusing on the relationship between _phronesis_ and other virtues. In particular, our focus will be on those that Miller ( 2023 ) has classified as Standard Model (...) and Eliminativist Model of practical wisdom. Starting from these accounts, we will outline three specific problems that the latter models appear to generate at a theoretical level in character education. Finally, we will address the task of demonstrating why the monist account of moral virtue recently proposed by the Aretai group—which conceives being virtuous in possessing _phronesis_ understood as ethical expertise—might offer a refined response to these challenges. In addition, we will illustrate three educational pathways that can emerge from the same model. (shrink)

The notion of causation that Mary Shepherd develops in her 1824 An Essay Upon the Relation of Cause and Effect (ERCE) has a number of surprising features that have only recently begun to be studied by scholars. This relation is synchronic, rather than diachronic (ERCE pp. 49–50); it always involves a ‘mixture’ of pre-existing objects (ERCE pp. 46–7); and the effect must be ‘a new nature, capable of exhibiting qualities varying from those of either of the objects unconjoined’ (ERCE p. (...) 63). In this essay, I argue for an emergentist interpretation of Shepherd’s causal theory. On the reading I defend, all effects have qualities that metaphysically emerge from the complex interactions of their constituents. This reading explains the structure of Shepherd’s causal relation and clarifies the central aims of her philosophical project. In response to the problems raised by the science of her time, Shepherd developed a theory of emergence and published it during the period when the concept was first being shaped and adopted by prominent philosophers. Her work thus merits a place in the history of emergentist ideas. (shrink)

Global Mental Health is a field of research and practice that addresses the expansion of universal and equitable mental health care worldwide. This article explores the ways the concept of culture is employed in Global Mental Health literature. Global Mental Health advocates and critics assume an ontological separation between ‘nature’ and ‘culture’ to typify mental illness, linking it predominantly to one or the other of these two categories. Advocates of Global Mental Health view mental disorders as a nature–culture hybrid, while (...) critics see them as typically cultural phenomena. The cultural critique of Global Mental Health can be strengthened by a sociological approach to both the role of critique and the uses of the concept of culture within social sciences. As an alternative to the ontologization of culture, we propose a different theoretical approach to the social issues involved in the expansion of international public health care in mental health: Arthur Kleinman's and Didier Fassin’s moral anthropological approaches.

This article focuses on human dignity as a moral idea and, in particular, on a single but fundamental question: what conception of human dignity, if any, can generate an egalitarian duty to respect all persons? After surveying two mainstream and two alternative conceptions, the article suggests that explaining how human dignity generates an egalitarian duty of respect may be more difficult than has been appreciated.

In spite of the burgeoning philosophical literature on human dignity, Stephen Darwall's second-personal account of the dignity of persons has not received the attention it deserves. This article investigates Darwall's account and argues that it faces a dilemma, for it succumbs either to a problem of antecedence or to the wrong kind of reasons problem. But this need not mean one should reject a second-personal account. Instead, I argue that an alternative second-personal conception, one I will call relational, promises to (...) solve the dilemma by avoiding both the problem of antecedence and the wrong kind of reasons problem. More generally, distinguishing these two second-personal conceptions of the dignity of persons is important to enrich the available philosophical accounts of human dignity. (shrink)

What ends should designers pursue? To what extent should they care about the societal and environmental impact of their work? And why should they care at all? Given the key influence design has on the way people live their lives, designing is fraught with ethical issues. Yet, unlike education or nursing, it lacks widespread professional principles for addressing these issues. -/- Rooted in a communitarian view of design practice, this lively and accessible book examines design through the lens of professions, (...) offering a critical vision that enables practitioners, academics and students of design in all disciplines to reflect on the practice’s overarching purposes. Considering how these are connected to others' flourishing and moulded by community interactions, "The Goods of Design" argues for a practice-based approach to cultivate professional ethics; it provides a normative direction that can meaningfully guide professional design activity, both individually and collectively. The volume also looks into the implications work has for the designer's self-growth as a person, offering ways to discover and navigate the complex tensions between personal and professional life.

In this paper I explore elements from Kant’s philosophy of right to develop a relational account of the wrong of poverty. Poverty is a relational wrong because it involves relations of problematic dependence, inequality, and humiliation. Such relations infringe the rights to freedom and equality of the poor. And the called-for response is one of public recognition and protection of the rights of the poor. This position means we must radically reconceptualize our individual duties to the poor: not _private beneficence_, (...) but _private remedies for public failures_. (shrink)

In addition to the familiar cardinal and proportional readings of many and few, there is yet another interpretation, the relative proportional reading. This reading, unlike the ordinary absolute proportional reading, is not conservative. Under the relative reading, 'Many ψs are φs' is true just in case the proportion of φs among ψs is greater than the proportion of φs among members of contextually given alternatives to ψ. I provide a definition of proportional readings that reduces the differences between absolute and (...) relative interpretations to the value of a single parameter.I argue that relative readings are not restricted to many and few, but are also exhibited by the adverbs often and seldom, and by generics. Interpretations of determiners that have been treated as "focus-affected readings," interpretations of adverbs of quantification that have been treated as "pure frequency readings," and interpretations of generics which have been claimed to be cases of "reverse interpretation" or "direct kind predication" are, in fact, instances of relative readings.A: Army reserve service is especially hard on people who own a small business.Q: Do many small-business owners serve in your regiment?A: I don't know what it's like in other regiments –Q: I am not asking you about other regiments.A: I know, but relatively speaking . . .(Interview on Israel Army Radio, June 8th, 2001).

Claiming rights against one another is a perfectly familiar phenomenon. We express the elementary thought you cannot do that to me in a variety of ways. And yet, in spite of the perfect familiarity of this phenomenon, the two standard philosophical theories of rights face notorious difficulties in accounting for it. My aim in this paper is to introduce a distinctive, second-personal account of rights. I will call this the independence theory of rights, the view that rights are specifications of (...) a basic right to independence against another. And I will argue that by taking as basic the second-personal thought you cannot do that to me the independence theory best illuminates the basic phenomenon of having rights against one another.

An interesting metatheoretical controversy took place during the 1980’s and 1990’s between pattern and phylogenetic cladists. What was always at stake in the discussion was not how work in systematics should be carried out, but rather how this practice should be metatheoretically interpreted. In this article, we criticize Pearson’s account of the metatheoretical factors at play in this discussion. Following him, we focus on the issue of circularity, and on the role that phylogenetic hypotheses play in the determination of “primary (...) homologies”. Pearson argues that the recognition of primary homologies cannot be achieved without recourse to previous phylogenetic knowledge, and that to claim otherwise is to state that primary homologies are observable. To show why that view would be inadequate, he appeals to Hanson’s views about theory-laden observation, alongside with a specific case study, which allegedly illustrates the more complex relation between observation and theory. We will argue that the pattern cladists’ point is better addressed by taking a quite different approach: instead of thinking in terms of observability, the topic can be tackled by paying attention to the way in which concepts are determined. We will take the notion of T-theoricity from metatheoretical structuralism and show that, once the issue is discussed with the appropriate metatheoretical framework, the alleged counterexample brought up by Pearson is not problematic at all for pattern cladism.

Lecture audiences and students were asked to respond to virtual decision and game situations at gametheory.tau.ac.il. Several thousand observations were collected and the response time for each answer was recorded. There were significant differences in response time across responses. It is suggested that choices made instinctively, that is, on the basis of an emotional response, require less response time than choices that require the use of cognitive reasoning.

While opinions on the semantic analysis of generics vary widely, most scholars agree that generics have a quasi-universal flavor. However, there are cases where generics receive what appears to be an existentialinterpretation. For example, B's response is true, even though only theplatypus and the echidna lay eggs: (1) A: Birds lay eggs. B: Mammals lay eggs too. In this paper I propose a uniform account of the semantics of generics,which accounts for their quasi-existential readings as well as for their more (...) familiar quasi-universal ones. Generics are focus-sensitiveoperators: their domain is restricted by a set of alternatives, which may be provided by focus. I claim that, unlike otherfocus-sensitive operators, generics may, but do not have to, associate with focus. When alternatives are introduced, either by focus or by other means, generics get their usual quasi-universal readings. But when no alternatives are introduced, quasi-existential readings result.I argue that generics, unlike adverbs of quantification, do not introduce tripartite structures directly, but are initially interpreted as cases ofdirect kind predication. Only when this interpretation fails to make sense, the phonologically null generic quantifier is derived, and tripartite structures result. This two-level interpretation has the effect that while adverbs of quantification require focus to determine which elements go to the restrictor and which to the nuclear scope, and hence must associate with focus, generics do not, and hence may fail to associate with focus, resulting in quasi-existential readings.

In this article, I examine the issue of the alleged circularity in the determination of homologies within cladistic analysis. More specifically, I focus on the claims made by the proponents of the dynamic homology approach, regarding the distinction (sometimes made in the literature) between primary and secondary homology. This distinction is sometimes invoked to dissolve the circularity issue, by upholding that characters in a cladistic data matrix have to be only primarily homologous, and thus can be determined independently of phylogenetic (...) hypotheses, by using the classical Owenian criteria (for morphological characters) or via multiple sequence alignment (for sequence data). However, since in the dynamic approach, sequence data can be analyzed without being pre-aligned, proponents have claimed that the distinction between primary and secondary homology has no place within cladistics. I will argue that this is not the case, since cladistic practice within the dynamic framework does presuppose primary homology statements at a higher level. (shrink)

Neuroeconomics is examined critically using data on the response times of subjects who were asked to express their preferences in the context of the Allais Paradox. Different patterns of choice are found among the fast and slow responders. This suggests that we try to identify types of economic agents by the time they take to make their choices. Nevertheless, it is argued that it is far from clear if and how neuroeconomics will change economics.

What on earth are economic theorists like me trying to accomplish? This paper discusses four dilemmas encountered by an economic theorist: The dilemma of absurd conclusions: Should we abandon a model if it produces absurd conclusions or should we regard a model as a very limited set of assumptions that will inevitably fail in some contexts? The dilemma of responding to evidence: Should our models be judged according to experimental results? The dilemma of modelless regularities: Should models provide the hypothesis (...) for testing or are they simply exercises in logic that have no use in identifying regularities?

How should we think about apparent conflicts of moral rights? I defend a non-balancing and holistic specification model: non-balancing because moral rights have absolute deontic stringency regardless of any balance of independent values; holistic because the content of moral rights is limited only by that of other moral rights. Holistic Specification, as I call the model, offers a principled, non-consequentialist explanation of exceptions to moral rights. Moreover, Holistic Specification explains why moral rights matter to practical thought while rendering remedial duties (...) less mysterious. (shrink)

The propensity account of fitness intends to solve the classical tautologicity issue by identifying fitness with a disposition, the ability to survive and reproduce. As proponents recognized early on, this account requires operational independence from actual reproductive success to avoid circularity and vacuousness charges. They suggested that operational independence is achieved by measuring fitness values through optimality models. Our goal in this article is to develop this suggestion. We show that one plausible procedure by which these independent operationalizations could be (...) thought to take place, and which is in accordance with what is said in the optimality literature, is unsound. We provide two independent lines of reasoning to show this. We then provide a sketch of a more adequate account of the role of optimality models in evolutionary contexts and draw some consequences.

We develop a framework for modeling choice in the presence of framing effects. An extended choice function assigns a chosen element to every pair (A, f ) where A is a set of alternatives and f is a frame. A frame includes observable information that is irrelevant in the rational assessment of the alternatives, but nonetheless affects choice. We relate the new framework to the classical model of choice correspondence. Conditions are identified under which there exists either a transitive or (...) a transitive and complete binary relation R such that an alternative x is chosen in some (A, f ) iff x is R-maximal in the set A. We then demonstrate that the framework of choice correspondence misses information, which is essential to economic modeling and which is incorporated in the extended choice function. (shrink)
