Embryonic development in a given species is orchestrated by genes regulating growth and differentiation in a stereotyped and conserved manner, resulting in embryos of consistent size and shape. Several signaling pathways, including that of Sonic Hedgehog (SHH), have been implicated in these processes. Recent experiments with Gas1 indicate that it may act as a growth-inducing gene, challenging its previous function as a gene specifically involved in growth arrest. Moreover, GAS1, a GPI-linked membrane protein, can bind SHH, suggesting an interacting link (...) between growth and patterning through SHH and GAS1.(1-4) BioEssays 24:22–26, 2002. © 2002 John Wiley & Sons, Inc.

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.

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.

This paper defends a rigorous reading of Hume’s critiques of arguments for the existence of God and of the belief in God against interpretations that endorse Humean theism, deism, and fideism. The latter include Donald Livingston’s theist reading, J. C. A. Gaskin’s “attenuated deism” reading, and Edward Kanterian’s “humble fideism” reading. I also examine whether Hume’s rejections of a positive theology commit him to agnosticism or atheism. My innovative challenge to such conclusions maintains that, while elements of both agnosticism and (...) atheism are found in Hume, these denote, respectively, a methodology and an incidental implication of his philosophy. But neither sufficiently captures his constructive vision for a society, individual psychology, and system of knowledge guided by naturalist principles and aims. For this, an alternate conception is needed that describes Hume’s philosophy of religion beyond mere atheism. (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)

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 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).

Recent research has shown that the superlative quantifiers at least and at most do not have the same type of truth conditions as the comparative quantifiers more than and fewer than. We propose that superlative quantifiers are interpreted at the level of speech acts. We relate them to denegations of speech acts, as in I don’t promise to come, which we analyze as excluding the speech act of a promise to come. Calling such conversational acts that affect future permissible speech (...) acts “meta-speech acts,” we introduce the meta-speech act of a GRANT of a proposition as a denial to assert the negation of that proposition. Superlative quantifiers are analyzed as quantifiers over GRANTS. Thus, John petted at least three rabbits means that the minimal number n such that the speaker GRANTs the proposition that John petted n rabbits is n = 3. We formalize this interpretation in terms of commitment states and commitment spaces, and show how the truth conditions that are derived from it are partly entailed and partly conversationally implicated. We demonstrate how the theory accounts for a wide variety of distributional phenomena of superlative quantifiers, including the contexts in which they can be embedded. (shrink)

Through hypothetical scenarios, this paper analyses whether machine learning (ML) could resolve one of the main shortcomings present in Christopher Boorse’s Biostatistical Theory of health (BST). In doing so, it foregrounds the boundaries and challenges of employing ML in formulating a naturalist (i.e., prima facie value-free) definition of health. The paper argues that a sweeping dataist approach cannot fully make the BST truly naturalistic, as prior theories and values persist. It also points out that supervised learning introduces circularity, rendering it (...) incompatible with a naturalistic perspective. Additionally, it underscores the need for pre-existing auxiliary theories to assess results from unsupervised learning. It emphasizes the importance of understanding the epistemological entanglements between data and data processing methods to manage expectations about what data patterns can predict. In conclusion, the paper argues against delegating the final authority for defining complex concepts like health to AI systems, as it necessitates ethical judgment and capacities for deliberation that AI currently lacks. It also warns against granting creators and deployers of AI systems the discretionary authority to determine these definitions outside the wider social discussion, advocating for ongoing public engagement on normative notions. Failure to do so risks limiting individuals and collectives’ ability to shape a just digital future and diminishes their fundamental epistemic agency. (shrink)

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)

In this paper we show that focus structure determines the interpretation of bare plurals in English: topic bare plurals are interpreted generically, focused bare plurals are interpreted existentially. When bare plurals are topics they must be specific, i.e. they refer to kinds. After type-shifting they introduce variables which can be bound by the generic quantifier, yielding characterizing generics. Existentially interpreted bare plurals are not variables, but denote properties that are incorporated into the predicate.The type of predicate determines the interpretation of (...) its bare plural subject. The individual/stage-level distinction, though important, is not sufficient: since only arguments can be topics, only those stage-level predicates which have locative arguments can have existential bare plural subjects.Certain verbs (e.g., hate) fail to incorporate their bare plural objects; therefore no existential reading of the object is available. We provide a novel solution to this puzzle based on the following two claims: (i) incorporated bare plurals do not introduce discourse referents; (ii) nonincorporating verbs are presuppositional.

This paper investigates the conceptual and empirical possibility of non-executed, non-conscious proximal intentions, i.e., non-conscious proximal intentions to act that do not turn into a final act, but perhaps are vetoed or overcome by an alternative action. It constructs a conceptual framework in which such cases are justifiably considered ‘proximal intentions’. This is achieved by combining Alfred Mele’s notion of non-conscious proximal intentions together with the notion of trying or striving taken from Brian O’Shaughnessy’s model of action. With this framework (...) in hand we analyze empirical electroencephalography (EEG) findings regarding ‘change of intention’ scenarios. Prior to EEG development (and other brain imaging techniques), one would never consider non-executed, non-conscious proximal intentions a case of intention at all. However, with technological and interpretable development of EEG, a whole group of so called ‘intentions’ appears, and the main aim of the paper is to justify this expanded usage. (shrink)

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)

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.

The superlative quantifiers, at least and at most, are commonly assumed to have the same truth-conditions as the comparative quantifiers more than and fewer than. However, as Geurts & Nouwen have demonstrated, this is wrong, and several theories have been proposed to account for them. In this paper we propose that superlative quantifiers are illocutionary operators; specifically, they modify meta-speech acts.Meta speech-acts are operators that do not express a speech act, but a willingness to make or refrain from making a (...) certain speech act. The classic example is speech act denegation, e.g. I don't promise to come, where the speaker is explicitly refraining from performing the speech act of promising What denegations do is to delimit the future development of conversation, that is, they delimit future admissible speech acts. Hence we call them meta-speech acts. They are not moves in a game, but rather commitments to behave in certain ways in the future. We formalize the notion of meta speech acts as commitment development spaces, which are rooted graphs: The root of the graph describes the commitment development up to the current point in conversation; the continuations from the root describe the admissible future directions.We define and formalize the meta-speech act GRANT, which indicates that the speaker, while not necessarily subscribing to a proposition, refrains from asserting its negation. We propose that superlative quantifiers are quantifiers over GRANTs. Thus, Mary petted at least three rabbits means that the minimal number n such that the speaker GRANTs that Mary petted n rabbits is n = 3. In other words, the speaker denies that Mary petted two, one, or no rabbits, but GRANTs that she petted more.We formalize this interpretation of superlative quantifiers in terms of commitment development spaces, and show how the truth conditions that are derived from it are partly entailed and partly conversationally implicated. We demonstrates how the theory accounts for a wide variety of phenomena regarding the interpretation of superlative quantifiers, their distribution, and the contexts in which they can be embedded.

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 aim of this article is twofold: first, to identify and address three central divisions in the field of authentic education that introduce ambiguity and at times inconsistencies within the field of authentic education. These divisions concern a) the relationship between autonomy and authenticity; b) the division between the two basic attitudes towards ‘care’ in the authenticity literature, and; c) the well-worn division between objective and subjective realms of knowledge and identity construction. Addressing these divisions through Charles Taylor's distinction between (...) active and passive aspects of authenticity, I believe, will lead to a better understanding of the main issues involved in conceptualising and applying authenticity-based education. Second, to present what I call The Postconventional Authentic Relation-to-Self as a basis for overcoming and reconciling the above divisions. I shall conclude by providing some examples of the way the perspective envisioned by PARTS can be applied to educational practices. (shrink)

This paper presents an updated reading of the Platonicconfrontation of Republic I, II, III and X with poets. Specifically, opposing the traditional readings that tend to focus on the ontological plane, this writing will investigate the Platonic warning about the plasticity and, consequently, the functionality of images. It is proposed as a contribution to redirect the criticism of poets to one of the central topics of Rep., the tension between appearance and reality, to account for their connection with the forms (...) of deception in πρᾶξις. In this sense, the objective is to show that the capacity of myths to form character and the social imaginary, as a dispositive of power, is anchored in the types of access and the ways of knowing that guide πρᾶξις. This will then allow us to rethink a current topic: the capacity of εἴδωλα, in a broad sense, to produce subjects and social values, as well as the ways of practical knowledge. (shrink)

I discuss conceptual confusions shared by deep ecologists over such questions as gender, essentialism, normative dualism, and eco-centrism. I conclude that deep ecologists have failed to grasp both the epistemological challenge offered by ecofeminism and the practical labor involved in bringing about social change. While convergencies between deep ecology and ecofeminism promise to be fruitful, these are celebrated in false consciousness, unless remedial work is done.

The article argues for the social production of curiosity. Due its motivating characteristic, curiosity is reconceptualized as an epistemic drive which organizes the social production of knowledge under given socio-historical and local-cultural circumstances. First, historical, philosophical, and sociological literature is reviewed to give a context for the argument. Then a theoretical apparatus is developed considering the emergence, development, and impact of epistemic drives which serves as a foundation for empirical analysis. The second part demonstrates applicability by discussing the problem of (...) economic incentives in scientific research. I argue that scientific projects with little to none immediate economic return have a significant disadvantage in acquiring funding which in turn impacts the mobilization of curiosity in their field. A tendency which systematically yields a disproportionate distribution of knowledge. In conclusion, the article suggests the usefulness of the epistemic drive notion in understanding curiosity as a sociological object. (shrink)

I discuss the design of the method of entropic inference as a general framework for reasoning under conditions of uncertainty. The main contribution of this discussion is to emphasize the pragmatic elements in the derivation. More specifically: (1) Probability theory is designed as the uniquely natural tool for representing states of incomplete information. (2) An epistemic notion of information is defined in terms of its relation to the Bayesian beliefs of ideally rational agents. (3) The method of updating from a (...) prior to a posterior probability distribution is designed through an eliminative induction process that singles out the logarithmic relative entropy as the unique tool for inference. The resulting framework includes as special cases both MaxEnt and Bayes’ rule. It therefore unifies entropic and Bayesian methods into a single general inference scheme. I find that similar pragmatic elements are an integral part of Putnam’s internal realism, of Floridi’s informational structural realism, and also of van Fraasen’s empiricist structuralism. I conclude with the conjecture that their valuable insights can be incorporated into a single coherent doctrine—an informational pragmatic realism. (shrink)

En el marco de los estudios actuales sobre la relación entre teoría y práctica de mímesis en Platón, el objetivo es indagar la caracterización [ethopoiía] platónica de Sócrates. Para tal fin, por un lado, se analiza la tematización de la caracterización en los Progymnásmata para mostrar su función y el lugar que ocupa Platón en esta tradición. Por otro lado, se estudian algunos pasajes clave de Apología de Sócrates y República I para echar luz sobre la composición narrativa, mímesis, y, (...) a través de ella, intentar dar cuenta del quehacer filosófico en la caracterización socrática. La hipótesis es que la opción por el diálogo está ligada no solo al modo de comprender, sino también al modo de transmitir el saber filosófico, y que, en tal marco, el personaje Sócrates encarna un tipo de saber hacer o disposicional. Este tipo de saber no sería reductible a proposiciones, de manera que la opción por el diálogo cumpliría una función no meramente estilística, sino fundamentalmente propedéutico-filosófica. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Literature 26.2 (2002) 260-272 [Access article in PDF] Tragic Conflict and Greatness of Character Ariel Meira IT IS A SURPRISING FACT that some of our best literary examples of greatness of character are of persons acting in a way that involves them in a terrible burden of guilt. As spectators we perceive Oedipus, in Sophocles's Oedipus the King, 1 as one who upon discovering the identity (...) of his father and mother affirms that he bears guilt for killing the former and committing incest with the latter, and we typically concur in some vague way with his affirmation. 2 We do not, after all, think that his affirmation is merely the consequence of some confusion about morals on his part, and that he would have been more justified in treating his discovery with a light conscience. Furthermore, it seems that our conception of his greatness is intimately bound up with our being acquainted with him as someone who acted so as to render himself profoundly guilty in this way. What is paradoxical is that moral taint would be expected to reduce our admiration for a character and our attribution of greatness to it. Why then should noteworthy paradigms of greatness of character be morally tainted characters? Can we make sense of the idea that some kinds of guiltiness might be constitutive of greatness of character?As it is well-known, Aristotle says that in order for a tragedy best to achieve its desired effect, it should portray a protagonist "who is not pre-eminent in moral virtue, who passes to bad fortune not through vice or wickedness, but because of some hamartia...." 3 The term "hamartia" is variously translated as "piece of ignorance," "miscalculation," and "error of judgment," but as O. B. Hardison notes, it must be treated as designating a moral flaw, because it renders the protagonist [End Page 260] less than "pre-eminent in moral virtue." 4 However, even if the term is interpreted as covering what I have described as the moral taint associated with greatness of character, it should be clear that Aristotle does not provide here an answer to my question. At best he can be viewed as explaining why morally tainted characters of this sort are crucial to achieving tragic effect. He is not explaining how it is that such characters can be viewed as paradigms of greatness.I propose not to treat this paradox in its most general form, but rather by confining my attention to an interesting subclass of cases. What I have in mind are cases in which a protagonist finds himself or herself in what I shall call circumstances of tragic conflict. Such circumstances determine that a choice must be made between two (or perhaps more) courses of action, even though each of the courses involves the violation of an important moral claim, or the destruction of a crucial value. As spectators or readers, we typically perceive the protagonist as emerging with a heavy burden of guilt (much in the way noted above regarding Oedipus), and we recognize that he or she was bound to emerge guilty, no matter which course of action would have been chosen. Cases such as that of Agamemnon (bearing guilt for the sacrifice of his daughter Iphigenia in Aeschylus's Agamemnon), 5 of Jephthah (again bearing guilt for the sacrifice of his daughter, in Judges 11), 6 and of Orestes (bearing guilt for the murder of his mother Clytemnestra in Euripides's Orestes) 7 belong quite uncontroversially to this subclass. 8These protagonists make difficult choices, and carry them out with courage and resolution, qualities which explain to some extent our perception of them as possessing greatness of character. But in making their choice, they necessarily render themselves guilty, whether or not they have made the correct choice (assuming there is a correct choice in the circumstances). And we sense that suffering the peculiarly poignant pain which accompanies their guilty action is at least partly constitutive of their greatness. Clearly, we are faced again with the paradox of the association of guilt with greatness of character.In... (shrink)

This article proposes to narrow the gap between the space of reasons and the space of causes. By articulating the standard phenomenology of reasons and causes, we investigate the cases in which the clear-cut divide between reasons and causes starts to break down. Thus, substituting the simple picture of the relationship between the space of reasons and the space of causes with an inverted and complex one, in which reasons can have a causal-like phenomenology and causes can have a reason-like (...) phenomenology. This is attained by focusing on “swift reasoned actions” on the one hand, and on “causal noisy brain mechanisms” on the other hand. In the final part of the article, I show how an analogous move, that of narrowing the gap between one’s normative framework and the space of reasons, can be seen as an extension of narrowing the gap between the space of causes and the space of reasons.

The paper argues that four-dimensionalism is incompatible with the existence of additively cumulative properties, including mass, volume, and electrical charge. These properties add up over disjoint objects: for example, the mass of a whole composed of two disjoint objects is a sum of the individual masses of the objects. The difficulty with such properties for four-dimensionalism stems from the way this theory makes persistence depend on the existence of disjoint objects at disjoint times. I consider various possible responses to this (...) difficulty and conclude that they all fail. (shrink)

The principle of Summation, which is a technically sharpened version of the familiar claim that a whole is a sum of its parts, is presented by Peter van Inwagen as a trivial truth. I argue to the contrary, that it is incompatible with the natural assumption that a whole may gain or lose parts non-instantaneously. For, as I show, the latter assumption implies that something can be determinately a whole without being determinately a sum of parts, and this, in turn, (...) indicates the falsity of Summation. I point out that the tension between Summation and the possibility of non-instantaneous gain or loss of parts compels us to rethink the relations between the concepts of whole and sum, and may have far reaching consequences for the mereology of physical objects.

ABSTRACT In several publications, François Recanati argues that time, world, location, and similar constituents are not arguments of the verb, although they do affect truth conditions. However, he points out that this fact does not decide the debate regarding whether these notions are represented as sentential operators variables bound by quantifiers, as both approaches can be made compatible with such non-arguments. He makes these points using philosophical arguments; in this paper I use linguistic evidence from a variety of languages. Specifically, (...) I demonstrate that time, world, location, and person behave syntactically and semantically the same across languages. Hence, either all are arguments, or neither are; and the evidence points to the latter position. The cross-linguistic data give rise to a generalization, which connects the availability of quantifying over times, worlds, locations, or persons with the availability of indexical expressions of the corresponding type. For example, a language that does not have temporal indexicals cannot have tense. I demonstrate that this generalization follows naturally from the quantifier approach, but would remain a mystery under the operator view. Therefore, the cross-linguistic evidence argues in the favor of the quantificational approach. (shrink)

Cognitive and affective penetration of perception refers to the influence that higher mental states such as beliefs and emotions have on perceptual systems. Psychological and neuroscientific studies appear to show that these states modulate the visual system at the visuomotor, attentional, and late levels of processing. However, empirical evidence showing that similar consequences occur in early stages of visual processing seems to be scarce. In this paper, I argue that psychological evidence does not seem to be either sufficient or necessary (...) to argue in favour of or against the cognitive penetration of perception in either late or early vision. In order to do that we need to have recourse to brain imaging techniques. Thus, I introduce a neuroscientific study and argue that it seems to provide well-grounded evidence for the cognitive penetration of early vision in face perception. I also examine and reject alternative explanations to my conclusion. (shrink)

Most solutions to the sorites reject its major premise, i.e. the quantified conditional . This rejection appears to imply a discrimination between two elements that are supposed to be indiscriminable. Thus, the puzzle of the sorites involves in a fundamental way the notion of indiscriminability. This paper analyzes this relation and formalizes it, in a way that makes the rejection of the major premise more palatable. The intuitive idea is that we consider two elements indiscriminable by default, i.e. unless we (...) know some information that discriminates between them. Specifically, following Rough Set Theory, two elements are defined to be indiscernible if they agree on the vague property in question. Then, a is defined to be indiscriminable from b if a is indiscernible by default from b . That is to say, a is indiscriminable from b if it is consistent to assume that a and b agree on the relevant vague property. (shrink)

According to current theories, sentences with definite descriptions that fail to refer are either false or lack a truth value; but they cannot be true. However, I present examples where such sentences are, in fact, judged true. I propose that a definite description may be accommodated as a conditional, and that, in such cases, it is precisely the failure to refer that makes the sentence true.

Hostages have become an important political and security issue in the context of conflicts in the Middle East and in Africa. The work of Marcel Mauss helps us to shed a new light on this phenomenon, which today is portrayed in negative terms as a major violation of fundamental universal rights such as the right to liberty. In The Gift, however, Mauss refers to the granting of hostages as “acts of generosity.” In line with Mauss’ approach, I consider hostageship as (...) a “total social phenomenon,” combining politics, law, and economics, in both domestic and global settings, which reveals structural political and social questions that need to be addressed. The article highlights the role that hostages fulfilled as “gifts” in premodern international relations when hostages were granted and not taken as they are today. I underline the role they notably performed as elements of proto-diplomacy. I show the reasons why the function of hostages has changed over time by underlining the importance of the later Middle A... (shrink)

What if claims about the future informed us about the intentions and the capabilities of our opponents to wage war against ourselves? Would and should the existing norms that restrict the preventive use of force change in the wake of such transformation? This article highlights the potential normative consequences of this change and discriminates between several possible normative evolutions. Would and should the “knowability of the future” alter radically the traditional rule of self-defense? This rule could indeed be jeopardized but, (...) as I argue in this paper, it should not. However, the distinction between preemption and prevention could become obsolete. Future claims about security will also induce new security doctrines as knowledge about the future would be used to signal one’s intentions and deter one’s opponent. This change would also have a significant impact on accountability, as citizens would have a more active role in discussions over foreign policy. Moreover, new modes of predictions and forecasting will challenge the traditional role of experts whose biases have hampered their analyses and anticipations. Thus, trustworthy future claims could bring significant progress in both ethical and political terms as they would trigger a debate on the role of knowledge in democratic societies. (shrink)

Law and economics scholarship has traditionally analyzed efficient breach cases monolithically. By grouping efficient breach cases together, this literature treats the subjective motives and the distributive effects of the breach as immaterial. The Restatement (Third) of Restitution and Unjust Enrichment introduced a distinction based on the intent and the effects of the breach, allowing courts to use disgorgement remedies in cases of ‘opportunistic’ breach of contract (i.e., ‘deliberate and profitable’ breaches). In this article, we evaluate this approach, focusing on the (...) effects of disgorgement remedies on allocative and productive efficiency, information-forcing and competitive effects, and restraint of breach-searching incentives. We show that, even from a purely consequentialist perspective, disgorgement remedies may be normatively warranted, especially when involving sellers’ breach. Recent experimental evidence revealed that the preferences and reactions of ordinary people are in line with our evaluation of the effects of opportunistic breach. (shrink)

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)

The adequacy of Elliott Sober’s analogy between classical mechanics and evolutionary theory—according to which both theories explain via a zero-force law and a set of forces that alter the zero-force state—has been criticized from various points of view. I focus here on McShea and Brandon’s claim that drift shouldn’t be considered a force because it is not directional. I argue that there are a number of different theses that could be meant by this, and show that one of those theses—the (...) idea that drift cannot bias populations to be taken somewhere in the evolutionary space from one generation to the next—is actually false. Not only has this thesis been implicitly assumed in the discussion of the force analogy thus far, but it is also commonly found in a wider range of philosophical and biological texts. I argue that correcting this view, and the usual images associated with it, will thereby bring heuristic benefits that impact the force analogy discussion, but that also go beyond it. (shrink)

In this article, I develop three conceptual innovations within the area of formal metatheory, and present a computer program, called Reconstructor, that implements those developments. The first development consists in a methodology for testing formal reconstructions of scientific theories, which involves checking both whether translations of paradigmatically successful applications into models satisfy the formalisation of the laws, and also whether unsuccessful applications do not. I show how Reconstructor can help carry this out, since it allows the end-user to specify a (...) formal language, input axioms and models formulated in that language, and then ask if the models satisfy the axioms. The second innovation is the introduction of incomplete models (for which the denotation of some terms is missing) into scientific metatheory, in order to represent cases of missing information. I specify the paracomplete semantics built into Reconstructor to deal with sentences where denotation failures occur. The third development consists in a new way of explicating the structuralist notion of a determination method, by equating them with algorithms. This allows determination methods to be loaded into Reconstructor and then executed within a model to find out the value of a previously non-denoting term (i.e. it allows the formal reconstruction to make predictions). This, in turn, can help test the reconstruction in a different way. Finally, I conclude with some suggestions about additional uses the program may have. (shrink)

RESUMO Busco traçar uma articulação teórica em torno de duas obras póstumas de Mikhail Bakhtin e Yuri Lotman, expoentes chave para pensar a cultura sob uma perspectiva semiótica. Nessas produções tardias, os dois pensadores expõem um interesse compartilhado em refletir como o medo se materializa, podendo-se ler em textos concretos que buscam explicar os fenômenos que estão ocorrendo no horizonte cultural. Nesse sentido, Lotman e Bakhtin estão focados em investigar a aparência regular de um conjunto de princípios e motivos que (...) seriam sistematicamente atualizados na relação entre laços sociais e medo. Meu objetivo vai além do descritivo para delinear aparatos críticos sobre o medo na perspectiva semiótica, à luz da interpretação desses artigos que mantêm o poder heurístico e fornecem um instrumento para iniciar uma reflexão sobre esse modo cultural de sentimento.ABSTRACT I seek to draw a theoretical articulation around two posthumous works by Mikhail Bakhtin and Yuri Lotman, key exponents to think about culture from a semiotic perspective. In these late productions, both thinkers expose a shared interest in reflecting how fear materializes, being able to be read in concrete texts that seek to account for the phenomena that are occurring on the cultural horizon. In this sense, Lotman and Bakhtin focus on investigating the regular appearance of a set of principles and motives that would be systematically updated in the relationship between social ties and fear. My purpose is not only to describe, but also to outline a critical apparatus about fear from a semiotic perspective, in light of the interpretation of these articles that keep heuristic power and provide an instrument to initiate a reflection on this cultural mode of feeling.RESUMEN Busco trazar una articulación teórica en torno a dos trabajos póstumos de Mikhail Bakhtin y Yuri Lotman, exponentes clave para pensar la cultura desde una perspectiva semiótica.

Let me start with what you should not do. Do not attend too many seminars in your own field. Otherwise you may simply end up adding a comment to the existing literature, which is mostly made up of comments on previous comments which were themselves only marginal comments. If you want a good idea, look at the world around you or take courses in other disciplines. Some of the papers in my own dissertation (like my 1979 paper on a principal-agent (...) problem with moral hazard and an infinite horizon) were thought of while daydreaming in some law courses I took.

This paper studies a decision maker who tackles a choice problem by selecting a subset of (at most) two alternatives which he will consider further in the second stage of his deliberation. We focus on the first stage where he chooses the delebration set. We axiomatize three types of procedures: (i) The top two: the decision maker has in mind an ordering and chooses the two maximal alternatives. (ii) The two extremes: the decision maker has in mind an ordering and (...) chooses the maximal and the minimal alternatives. (iii) The top and the top: the decision maker has in mind two orderings and he chooses the maximal elements. (shrink)

The present work analyzes the controversy within biological systematics regarding the status of cladistics. The use of the parsimony method for phylogenetic reconstruction has been defended by appealing to a methodological principle of simplicity, as well as to empirical principles that external to systematics. I propose new kind of approach, which consists in considering it an empirical theory, thus justifying its application by its empirical success. To defend this point, a formal structuralist reconstruction of cladistics will be provided, which will (...) help clarify what its central empirical statements are. At the same time, I show how these principles have been used to test that theory using experimental phylogenies. (shrink)

This article elaborates on McShea and Brandon’s idea that drift is unlike the rest of the evolutionary factors because it is constitutive rather than imposed on the evolutionary process. I show that the way they spelled out this idea renders it inadequate and is the reason why it received some objections. I propose a different way in which their point could be understood, that rests on two general distinctions. The first is a distinction between the underlying mathematical apparatus used to (...) formulate a theory and a concept proposed by that theory. With the aid of a formal reconstruction of a population genetic model, I show that drift belongs to the first category. That is, that drift is constitutive of population genetics in the same sense that multiplication is constitutive in classical mechanics, or that circle is constitutive in Ptolemaic astronomy. The second distinction is between eliminating a concept from a theory and setting its value to zero. I will show that even though drift can be set to zero just like the rest of the evolutionary factors, eliminating drift is much harder than eliminating those other factors, since it would require changing the entire mathematical apparatus of standard population genetic theory. I conclude by drawing some other implications from the proposed formal reconstruction. (shrink)
