We study and compare two combinatorial lowness notions: strong jump-traceability and well-approximability of the jump, by strengthening the notion of jump-traceability and super-lowness for sets of natural numbers. A computable non-decreasing unbounded function h is called an order function. Informally, a set A is strongly jump-traceable if for each order function h, for each input e one may effectively enumerate a set Te of possible values for the jump JA, and the number of values enumerated is at most h. A′ (...) is well-approximable if can be effectively approximated with less than h changes at input x, for each order function h. We prove that there is a strongly jump-traceable set which is not computable, and that if A′ is well-approximable then A is strongly jump-traceable. For r.e. sets, the converse holds as well. We characterize jump-traceability and strong jump-traceability in terms of Kolmogorov complexity. We also investigate other properties of these lowness properties. (shrink)

In this paper we study the Kolmogorov complexity for non-effective computations, that is, either halting or non-halting computations on Turing machines. This complexity function is defined as the length of the shortest input that produce a desired output via a possibly non-halting computation. Clearly this function gives a lower bound of the classical Kolmogorov complexity. In particular, if the machine is allowed to overwrite its output, this complexity coincides with the classical Kolmogorov complexity for halting computations relative to the first (...) jump of the halting problem. However, on machines that cannot erase their output –called monotone machines–, we prove that our complexity for non effective computations and the classical Kolmogorov complexity separate as much as we want. We also consider the prefix-free complexity for possibly infinite computations. We study several properties of the graph of these complexity functions and specially their oscillations with respect to the complexities for effective computations. (shrink)

We consider the question of randomness of the probability ΩU[X] that an optimal Turing machine U halts and outputs a string in a fixed set X. The main results are as follows: ΩU[X] is random whenever X is $\Sigma _{n}^{0}$-complete or $\Pi _{n}^{0}$-complete for some n ≥ 2. However, for n ≥ 2, ΩU[X] is not n-random when X is $\Sigma _{n}^{0}$ or $\Pi _{n}^{0}$ Nevertheless, there exists $\Delta _{n+1}^{0}$ sets such that ΩU[X] is n-random. There are $\Delta _{2}^{0}$ sets (...) X such that ΩU[X] is rational. Also, for every n ≥ 1, there exists a set X which is $\Delta _{n+1}^{0}$ and $\Sigma _{n}^{0}$-hard such that ΩU[X] is not random. We also look at the range of ΩU as an operator. We prove that the set {ΩU[X]: X ⊆ 2<ω} is a finite union of closed intervals. It follows that for any optimal machine U and any sufficiently small real r, there is a set X ⊆ 2<ω recursive in ∅′ ⊕ r, such that ΩU[X] = r. The same questions are also considered in the context of infinite computations, and lead to similar results. (shrink)

We define a program size complexity function $H^\infty$ as a variant of the prefix-free Kolmogorov complexity, based on Turing monotone machines performing possibly unending computations. We consider definitions of randomness and triviality for sequences in ${\{0,1\}}^\omega$ relative to the $H^\infty$ complexity. We prove that the classes of Martin-Löf random sequences and $H^\infty$-random sequences coincide and that the $H^\infty$-trivial sequences are exactly the recursive ones. We also study some properties of $H^\infty$ and compare it with other complexity functions. In particular, $H^\infty$ (...) is different from $H^A$, the prefix-free complexity of monotone machines with oracle A. (shrink)

We investigate the expressive power of memory logics. These are modal logics extended with the possibility to store (or remove) the current node of evaluation in (or from) a memory, and to perform membership tests on the current memory. From this perspective, the hybrid logic (↓), for example, can be thought of as a particular case of a memory logic where the memory is an indexed list of elements of the domain.

First collected in Italy in 1985, _Art's Claim to Truth_ is considered by many philosophers to be one of Gianni Vattimo's most important works. Newly revised for English readers, the book begins with a challenge to Plato, Aristotle, Kant, and Hegel, who viewed art as a metaphysical aspect of reality rather than a futuristic anticipation of it. Following Martin Heidegger's interpretation of the history of philosophy, Vattimo outlines the existential ontological conditions of aesthetics, paying particular attention to the works of (...) Kandinsky, which reaffirm the ontological implications of art. Vattimo then builds on Hans-Georg Gadamer's theory of aesthetics and provides an alternative to a rationalistic-positivistic criticism of art. This is the heart of Vattimo's argument, and with it he demonstrates how hermeneutical philosophy reaffirms art's ontological status and makes clear the importance of hermeneutics for aesthetic studies. In the book's final section, Vattimo articulates the consequences of reclaiming the ontological status of aesthetics without its metaphysical implications, holding Aristotle's concept of beauty responsible for the dissolution of metaphysics itself. In its direct engagement with the works of Gadamer, Heidegger, and Luigi Pareyson, _Art's Claim to Truth_ offers a better understanding of the work of Vattimo and a deeper knowledge of ontology, hermeneutics, and the philosophical examination of truth.

Though coming from different and distinct intellectual traditions, Richard Rorty and Gianni Vattimo are united in their criticism of the metaphysical tradition. The challenges they put forward extend beyond philosophy and entail a reconsideration of the foundations of belief in God and the religious life. They urge that the rejection of metaphysical truth does not necessitate the death of religion; instead it opens new ways of imagining what it is to be religious -- ways that emphasize charity, solidarity, and irony. (...) This unique collaboration, which includes a dialogue between the two philosophers, is notable not only for its fusion of pragmatism and hermeneutics but also for its recognition of the limits of both traditional religious belief and modern secularism. In "Anticlericalism and Atheism" Rorty discusses Vattimo's work _Belief_ and argues that the end of metaphysics paves the way for an anti-essentialist religion. Rorty's conception of religion, determined by private motives, is designed to produce the gospel's promise that henceforth God will not consider humanity as a servant but as a friend. In "The Age of Interpretation," Vattimo, who is both a devout Catholic and a frequent critic of the church, explores the surprising congruence between Christianity and hermeneutics in light of the dissolution of metaphysical truth. As in hermeneutics, interpretation is central to Christianity, which introduced the world to the principle of interiority, dissolving the experience of objective reality into "listening to and interpreting messages." The lively dialogue that concludes this volume, moderated and edited by Santiago Zabala, analyzes the future of religion together with the political, social, and historical aspects that characterize our contemporary postmodern, postmetaphysical, and post-Christian world.

In _Basic Concepts_, Heidegger claims that "Being is the most worn-out" and yet also that Being "remains constantly available." Santiago Zabala radicalizes the consequences of these little known but significant affirmations. Revisiting the work of Jacques Derrida, Reiner Schürmann, Jean-Luc Nancy, Hans-Georg Gadamer, Ernst Tugendhat, and Gianni Vattimo, he finds these remains of Being within which ontological thought can still operate. Being is an event, Zabala argues, a kind of generosity and gift that generates astonishment in those who experience (...) it. This sense of wonder has fueled questions of meaning for centuries-from Plato to the present day. Postmetaphysical accounts of Being, as exemplified by the thinkers of Zabala's analysis, as well as by Nietzsche, Dewey, and others he encounters, don't abandon Being. Rather, they reject rigid, determined modes of essentialist thought in favor of more fluid, malleable, and adaptable conceptions, redefining the pursuit and meaning of philosophy itself. (shrink)

A daring marriage of philosophical theory and practical politics, this collection is the first of Gianni Vattimo's many books to combine his intellectual pursuits with his public and political life. Vattimo is a paradoxical figure, at once a believing Christian and a vociferous critic of the Catholic Church, an outspoken liberal but not a former communist, and a recognized authority on Nietzsche and Heidegger as well as a prominent public intellectual and member of the European parliament. Building on his unique (...) position as a philosopher and politician, Vattimo takes on some of the most pressing questions of our time: Is it still possible, long after Nietzsche proclaimed the death of God, to talk of moral imperatives, individual rights, or political freedom? Are these values still relevant in today's world? Tackling these crucial issues, Gianni Vattimo argues that nihilism is not the absence of meaning but a recognition of a plurality of meanings; it is not the end of civilization but the beginning of new social paradigms. Commonly associated with the pessimistic belief that all of existence is meaningless, nihilism, as a philosophical principle, is far less sensational -- it is the ethical doctrine that there are no moral absolutes or infallible natural laws, that "truth" is inescapably subjective. Because the conditions for equality and liberty are not "naturally" given, society must actively create these ideals or it will inevitably fall prey to irrationality, prejudice, and oppression. Vattimo contends that the infighting, timidity, and confusion that have overtaken contemporary liberal thought and politics are the products a prolonged and indulgent mourning over the loss of the transcendental father figure -- any institution or power structure that defines truth, knowledge, and reality. Until humanity overcomes its need for external authority -- whether it be organized religion, the nation-state, or free-market capitalism -- emancipation will remain unattainable. Collecting fourteen of Vattimo's most influential essays on ethics, politics, and law, _Nihilism and Emancipation_ is a provocative reevaluation of meaning, values, and the idea of freedom in Western culture.

Contemporary philosophers—analytic as well as continental—tend to feel uneasy about Ernst Tugendhat, who, though he positions himself in the analytic field, poses questions in the Heideggerian style. Tugendhat was one of Martin Heidegger's last pupils and his least obedient, pursuing a new and controversial critical technique. Tugendhat took Heidegger's destruction of Being as presence and developed it in analytic philosophy, more specifically in semantics. Only formal semantics, according to Tugendhat, could answer the questions left open by Heidegger. Yet in doing (...) this, Tugendhat discovered the latent "hermeneutic nature of analytic philosophy"—its post-metaphysical dimension—in which "there are no facts, but only true propositions." What Tugendhat seeks to answer is this: What is the meaning of thought following the linguistic turn? Because of the rift between analytic and continental philosophers, very few studies have been written on Tugendhat, and he has been omitted altogether from several histories of philosophy. Now that these two schools have begun to reconcile, Tugendhat has become an example of a philosopher who, in the words of Richard Rorty, "built bridges between continents and between centuries." Tugendhat is known more for his philosophical turn than for his phenomenological studies or for his position within analytic philosophy, and this creates some confusion regarding his philosophical propensities. Is Tugendhat analytic or continental? Is he a follower of Wittgenstein or Heidegger? Does he belong in the culture of analysis or in that of tradition? Santiago Zabala presents Tugendhat as an example of merged horizons, promoting a philosophical historiography that is concerned more with dialogue and less with classification. In doing so, he places us squarely within a dialogic culture of the future and proves that any such labels impoverish philosophical research. (shrink)

Theories of emotional justification investigate the conditions under which emotions are epistemically justified or unjustified. I make three contributions to this research program. First, I show that we can generalize some familiar epistemological concepts and distinctions to emotional experiences. Second, I use these concepts and distinctions to display the limits of the ‘simple view’ of emotional justification. On this approach, the justification of emotions stems only from the contents of the mental states they are based on, also known as their (...) cognitive bases. The simple view faces the ‘gap problem’: If cognitive bases and emotions (re)present their objects and properties in different ways, then cognitive bases are not sufficient to justify emotions. Third, I offer a novel solution to the gap problem based on emotional dispositions. This solution (1) draws a line between the justification of basic and non-basic emotions, (2) preserves a broadly cognitivist view of emotions, (3) avoids a form of value skepticism that threatens inferentialist views of emotional justification, and (4) sheds new light on the structure of our epistemic access to evaluative properties.

This paper introduces a body of research on Organizational Behavior and Industrial/organizational Psychology that expands the range of empirical evidence relevant to the ongoing character-situation debate. This body of research, mostly neglected by moral philosophers, provides important insights to move the debate forward. First, the OB/io scholarship provides empirical evidence to show that social environments like organizations have significant power to shape the character traits of their members. This scholarship also describes some of the mechanisms through which this process of (...) reshaping character takes place. Second, the character-situation debate has narrowly focused on situational influences that affect behavior episodically and haphazardly. The OB/io research, however, highlights the importance of distinguishing such situational influences from influences that, like organizational influences, shape our character traits because they are continuous and coordinated. Third, the OB/io literature suggests that most individuals display character traits that, while local to the organization, can be consistent across situations. This puts pressure on the accounts of character proposed by traditional virtue ethics and situationism and provides empirical support to interactionist models based on cognitive-affective processing system theories of personality. Finally, the OB/io literature raises important challenges to the possibility of achieving virtue, provides valuable and untapped resources to cultivate character, and suggests new avenues of normative and empirical research.

Scholars who favor shareholder primacy usually claim either that managers should not fulfill corporate duties of beneficence or that, if they are required to fulfill them, they do so by going against their obligations to shareholders. Distinguishing between structurally different types of duties of beneficence and recognizing the full force of the normative demands imposed on managers reveal that this view needs to be qualified. Although it is correct to think that managers, when acting on behalf of shareholders, are not (...) required to fulfill wide duties of charity, they are nevertheless required to fulfill a variety of narrow duties of beneficence. What is more, the obligation to fulfill these duties arises precisely because they are acting on behalf of shareholders. As such, this article 1) refines our understanding of the duties of corporate beneficence and 2) helps to identify which duties of beneficence are imposed on managers when they are acting on behalf of shareholders.

In this paper, we argue for an instrumental form of existence, inspired by Hilbert’s method of ideal elements. As a case study, we consider the existence of contradictory objects in models of non-classical set theories. Based on this discussion, we argue for a very liberal notion of existence in mathematics.

According to epistemological disjunctivism (ED), in paradigmatic cases of perceptual knowledge, a subject, S, has perceptual knowledge that p in virtue of being in possession of reasons for her belief that p which are both factive and reflectively accessible to S. It has been argued that ED is better placed than both knowledge internalism and knowledge externalism to undercut underdetermination-based skepticism. I identify several principles that must be true if ED is to be uniquely placed to attain this goal. After (...) that, I use those principles to formulate a diachronic skeptical argument. This argument yields the counterintuitive conclusion that understanding a global skeptical hypothesis is all it takes for a rational subject to lose all her perceptual knowledge of the world. Next, I show that a popular Austinian move must reject one or another of the principles that underlie ED. I close by delineating a novel strategy that can block the diachronic skeptical argument while preserving all the principles. The key idea is that perceptual knowledge is grounded in primitive, perceptual and recognitional abilities. This view sheds new light on some puzzling features of global skepticism that have been noted by Descartes and Hume, among others. (shrink)

I will also point out many consequences that my proposal has about a few metatheoretical discussions around the theory and, finally, I will relate my propose to other reconstructions available.

Evidence from cognitive science supports the claim that humans and other animals see the world as divided into objects. Although this claim is widely accepted, it remains unclear whether the mechanisms of visual reference have representational content or are directly instantiated in the functional architecture. I put forward a version of the former approach that construes object files as icons for objects. This view is consistent with the evidence that motivates the architectural account, can respond to the key arguments against (...) representational accounts, and has explanatory advantages. I draw general lessons for the philosophy of perception and the naturalization of intentionality. (shrink)

Este libro analiza y reconstruye una de las teorías científicas que más discusiones han provocado en el ámbito de la biología, de la filosofía y de la sociedad: la teoría de la selección natural. Esta teoría, que ocupa un lugar central en la biología evolutiva, se encuentra en el centro de la revolución darwiniana, uno de los cambios más radicales ocurridos en la historia de la ciencia y, sin dudas, uno de los que más consecuencias han tenido sobre la ciencia (...) en general, sobre la filosofía y sobre el mismo modo en que nos percibimos en el mundo. -/- Si bien se trata de una teoría que parece sencilla de comprender, ha sido especialmente elusiva a los intentos de reconstrucción, no hay acuerdo con respecto a su estructura ni a cuáles son sus conceptos fundamentales. En este trabajo, asumiendo el marco conceptual brindado por el estructuralismo metateórico, se propone una reconstrucción que permite no solo dar cuenta adecuadamente del modo en que la teoría funciona en la práctica científica actual, sino que, además, permite explicitar la importancia filosófica antes aludida. -/- Frente a los desacuerdos marcados en la filosofía de la biología, pero también en textos y manuales de los biólogos evolutivos, respecto del modo de presentación adecuado y la naturaleza de la teoría, la estrategia reconstructiva consiste en discutir la teoría en su origen, tal como apareció en los textos de uno de sus codescubridores, Charles Darwin. La intención del libro es, entonces, no solo explicitar la estructura de la teoría, sino, además, su lugar en el pensamiento de Darwin, en la revolución darwiniana y en la biología evolutiva.

ABSTRACT:The distinction between what I call nonelective obligations and discretionary obligations, a distinction that focuses on one particular thread of the distinction between perfect and imperfect duties, helps us to identify the obligations that carry over from principals to agents. Clarity on this issue is necessary to identify the moral obligations within “shareholder primacy”, which conceives of managers as agents of shareholders. My main claim is that the principal-agent relation requires agents to fulfill nonelective obligations, but it does not always (...) require discharging discretionary obligations. I show that the requirement to fulfill nonelective obligations is more far-reaching than has been acknowledged by most defenders and critics of shareholder primacy. But I also show that managers are not bound by certain discretionary obligations like charity, showing that their moral obligations are more circumscribed than the obligations that apply to human beings in general.

Object files are mental representations that enable perceptual systems to keep track of objects as numerically the same. How is their reference fixed? A prominent approach, championed by Zenon Pylyshyn and John Campbell, makes room for a non-satisfactional use of properties to fix reference. This maneuver has enabled them to reconcile a singularist view of reference with the intuition that properties must play a role in reference fixing. This paper examines Campbell’s influential defense of this strategy. After criticizing it, a (...) new approach is sketched. The alternative view introduces representational contents to explain perceptual individuation. After arguing that those contents are not satisfactional, it is concluded that there is room for a third view of reference fixing that does not fit into the singularist/descriptivist dichotomy.

Epistemological disjunctivism (ED) has been thought to solve the conditionality problem for epistemic externalism. This problem arises from externalists’ characterization of our epistemic standings as conditional on the obtaining of worldly facts which we lack any reflective access to. ED is meant to avoid the conditionality problem by explicating subjects’ perceptual knowledge in paradigmatic cases of perceptual knowledge via their possession of perceptual reasons that are both factive and reflectively accessible. I argue that ED’s account of reflectively accessible factive perceptual (...) reasons is also prey to the conditionality problem. After that, I submit that Stroud’s influential formulation of the conditionality problem relies on a methodological requirement that is potentially dissociable from ED. So, it is possible to put ED in the service of a more modest anti-skeptical strategy. I close by suggesting that this modest anti-skeptical strategy successfully undercuts the underdetermination-based skeptical paradox. Nevertheless, it does not have substantial advantages over some forms of epistemic externalism. (shrink)

This article considers HLA Hart's influence in the making of John Finnis's book Natural Law and Natural Rights. In the style of an intellectual biography it traces the history of the interaction between the two Oxford legal philosophers using their correspondence as a starting point. It also delves into Finnis's years in Africa—a period of his life both crucial for the writing of the book and utterly unknown. It argues that Hart's role was significant not only insofar as he was (...) behind the idea of the book but also because of the restrained way in which he freely chose to conduct his role as editor despite the extent of the reservations he had regarding Finnis's work, fully revealed here. Given the importance of Natural Law and Natural Rights for what has been called the ‘new natural law theory’ the article concludes by awarding Hart his due credit in the making of one of that theory's main sources of inspiration.

Suele señalarse la fuerte influencia que la teología natural tuvo sobre Darwin en su conceptualización del fenómeno de la adaptación. La teoría de la selección natural explicaría el mismo fenómeno que los teólogos naturales querían explicar: la adaptación. Recientemente ha sido señalado, sin embargo, que la forma darwiniana de conceptualizar la adaptación es novedosa. Las adaptaciones de la teología natural presupondrían la idea de que los organismos existen para la realización y manutención del equilibrio natural establecido por el creador. El (...) punto de este trabajo discutir esta cuestión, asumiendo el marco del estructuralismo metateórico. The strong influence that natural theology had over Darwin’s conceptualization of the adaptation phenomenon is frequently noted. The natural selection theory would explain the same phenomenon that the natural theologist intended to explain: the adaptation. Recently has been claimed, on the contrary, that the Darwinian way of conceptualizing adaptation is new. The concept of adaptation from natural theology presupposes the idea that organisms exist for realization and support of the natural equilibrium stated by the creator. In this work I will discuss this point, assuming the metatheoretical structuralism frame. (shrink)

The concept of fitness has generated a lot of discussion in philosophy of biology. There is, however, relative agreement about the need to distinguish at least two uses of the term: ecological fitness on the one hand, and population genetics fitness on the other. The goal of this paper is to give an explication of the concept of ecological fitness by providing a reconstruction of the theory of natural selection in which this concept was framed, that is, based on the (...) way the theory was put to use in Darwin’s main texts. I will contend that this reconstruction enables us to account for the current use of the theory of natural selection. The framework presupposed in the analysis will be that of metatheoretical structuralism. This framework will provide both a better understanding of the nature of ecological fitness and a more complete reconstruction of the theory. In particular, it will provide what I think is a better way of understanding how the concept of fitness is applied through heterogeneous cases. One of the major advantages of my way of thinking about natural selection theory is that it would not have the peculiar metatheoretical status that it has in other available views. I will argue that in order to achieve these goals it is necessary to make several concepts explicit, concepts that are frequently omitted in usual reconstructions. (shrink)

In this paper I tried to find a harm based solution to the non-identity problem. I explore the view upon which future persons are harmed if we prevent them from having what it is required by the Principle of Utility.

The scholarship on meaningful work has approached the topic mostly from the perspective of the subjective experience of the individual worker. This has led the literature to under-theorize, if not outright ignore, the cultural and normative dimension of meaningful work. In particular, it has obscured that a person’s ability to find meaning in her life in general, and her work in particular, is typically anchored and dependent on shared institutions and cultural aspirations. Reflecting on the future of work, particularly on (...) the dangers posed by the threat of technological unemployment, helps us recognize this cultural and normative dimension of meaningful work. I argue that a world with few work opportunities is a world devoid of a core structuring ideal around which our society has organized itself and, as such, will strain our ability to make sense of what it means to find life meaningful. To make this case I show that work operates as a central organizing _telos_ around which our contemporary lives gravitate. Work touches everyone and everything, defining the rhythms of our days and weeks and providing a center of gravity around which our lives are structured. Work constitutes a central dimension of human flourishing. Through work we provide for our material needs, develop our skills and virtues, build community, and contribute to the common good. As such, work constitutes a central organizing ideal in contemporary Western societies, a fact has significant normative force and plays an important role in our finding work meaningful. (shrink)

Radical skepticism relies on the hypothesis that one could be completely cut off from the external world. In this paper, I argue that this hypothesis can be rationally motivated by means of a conceivability argument. Subsequently, I submit that this conceivability argument does not furnish a good reason to believe that one could be completely cut off from the external world. To this end, I show that we cannot adequately conceive scenarios that verify the radical skeptical hypothesis. Attempts to do (...) so fall prey to one or another of three pitfalls: they end up incomplete, reveal a deep contradiction or recreate a non-skeptical hypothesis. I use these results to improve upon Pritchard’s recent attempt at undercutting radical skepticism. (shrink)

A fim de celebrar o bicentenário da publicação d´ O mundo como vontade e representação, rememoraremos uma polêmica de grandes proporções na filosofia alemã ao final do século XIX: a Pessimismus-Frage. Originada pela recepção da filosofia schopenhaueriana, essa polêmica suscitou – sobretudo após a morte de Schopenhauer - extensos debates entre os partidários do pessimismo filosófico e seus críticos. Iniciaremos descrevendo algumas características do horizonte intelectual alemão da época. A seguir, apresentaremos traços do pensamento de três representantes da chamada escola (...) de Schopenhauer, defensores do pessimismo filosófico. Posteriormente, elencaremos algumas das principais críticas dirigidas contra Schopenhauer e seu pessimismo, oriundas sobretudo do movimento neokantiano, ora dominante na filosofia universitária alemã. Concluiremos mostrando como a Pessimismus-Frage tinha como pressuposto uma discussão acerca da natureza e dos limites da própria filosofia, ressaltando a influência da filosofia schopenhaueriana durante a segunda metade do século XIX na Alemanha.

Austere relationism rejects the orthodox analysis of hallucinations and illusions as incorrect perceptual representations. In this article, I argue that illusions of optimal motion present a serious challenge for this view. First, I submit that austere-relationist accounts of misleading experiences cannot be adapted to account for IOMs. Second, I show that any attempt at elucidating IOMs within an austere-relationist framework undermines the claim that perceptual experiences fundamentally involve relations to mind-independent objects. Third, I develop a representationalist model of IOMs. The (...) proposed analysis combines two ideas: Evans' dynamic modes of presentation and Fine's relational semantics for identity. (shrink)

It is widely assumed that perception is a source of reasons (SR). There is a weak sense in which this claim is trivially true: even if one characterizes perception in purely causal terms, perceptual beliefs originate from the mind's interaction with the world. When philosophers argue for (SR), however, they have a stronger view in mind: they claim that perception provides pre- or non-doxastic reasons for belief. In this article I examine some ways of developing this view and criticize them. (...) I exploit these results to formulate a series of constraints that a satisfactory account of the epistemic role of perception should fulfil. I also make a positive suggestion: coherentists are right when they claim that only beliefs can be reasons for other beliefs. Nevertheless, I depart from traditional coherentism, for I do not buy its conception of perception as bare sensation, nor explicate the justificatory status of beliefs in terms of coherence. My point is rather that, when one invokes experience to justify a belief, the justifying state must have structural features of beliefs. (shrink)

En On the Origin of Species Darwin distingue explícitamente entre tres tipos de selección: la selección natural, la artificial y la sexual. En este trabajo, a partir de un estudio más sistemático que historiográfico, se intenta encontrar la relación entre estos tres tipos de selección en la obra de Darwin. Si bien la distinción entre estos distintos mecanismos es de suma importancia en la obra de Darwin, la tesis de este trabajo es que tanto la selección artificial como la sexual (...) no son mecanismos distintos de la selección natural. Particularmente se sostiene que la selección artificial y la sexual son casos de la natural, y por esto sirven para su contrastación. (shrink)

La sobrecarga de información resulta un problema epistemológico que preocupa a distintas áreas del conocimiento tales como al campo de las ciencias cognitivas, en su intento por modelar sistemas capaces de detectar relevancia como a la ya olvidada enciclopedística, practicada durante los siglos XVI- XVIII y abocada a la organización, disposición y difusión de la información científica de la época. El presente artículo intenta dar cuenta del fracaso de estos dos campos de investigación a la hora de hallar soluciones ante (...) la problemática de la sobrecarga informacional. Para abordar nuestra cuestión clave, examinaremos particularmente las miradas relativamente pesimistas de H. Dreyfus y de Novalis. Los tratamientos de estos autores demuestran que la sobrecarga de información no puede, ni podrá ser resuelta, si no se recurre a otra vía de investigación por fuera de aquellas que se muestran como insuficientes, a saber: el modelo computacional de la mente (Dreyfus) y la operación enciclopedística clasificatoria (Novalis).

The rule account of self-conscious thought holds that a thought is self-conscious if and only if it contains a token of a concept-type that is governed by a reflexive rule. An account along these lines was discussed in the late 70s. Nevertheless, very few philosophers endorse it nowadays. I shall argue that this summary dismissal is partly unjustified. There is one version of the rule account that can explain a key epistemic property of self-conscious thoughts: Guarantee. Along the way, I (...) will rebut a number of objections and introduce two constraints on how the reflexive rule is implemented. (shrink)
