Throughout the present text, an account of the main contributions of Luis Villoro Toranzo will be made as a tribute to three years after his death.

This article presents what I call the Central Normative Proposal of Luis Villoro. This proposal is based on an interpretation of the principle of non-exclusion in ethics and epistemology. The core argument of the paper is based on a linguistic analogy that demonstrates the importance of reasonable communication for non-exclusion in epistemology, which is assumed in various theses of Villoro. A consequence of this analogy for non-exclusion in ethics is that Villoro defends basing what is reasonable on (...) the concrete possibilities of mutual understanding, starting with asymmetries and injustices that are obfuscated or eliminated in a contractualist analysis, or one that begins with strictly egalitarian principles. This criticism is compatible with egalitarian views, but it assumes a radically different point of departure. Although various theses by Villoro are compatible with egalitarian notions, given this point of departure based on asymmetries of power his proposal should be understood based on our cognitive capacities to understand and appreciate such asymmetries. For this reason, the paper concludes with an analysis of the notion of reasonableness, which under my interpretation Villoro defines in terms of our capacities for attention, that are not reducible to beliefs or systems of beliefs. In this way, the Central Normative Proposal of Villoro depends on the convergence between truth and the dignity of the members of communities in which as matter-of-fact asymmetries exist and must be eliminated through concrete communicative efforts.

Kim Diaz's translation of Guillermo Hurtado's "Retratos de Luis Villoro".

Contrasting two models of deliberative democratic multiculturalism, one by Seyla Benhabib and another by Luis Villoro, this paper contends that the differences between these two models outweigh the similarities, and that Villoro’s model is more promising insofar as it preserves the trust required in the institutions that mediate democratic deliberation in multicultural societies.

Se trata de una reflexión que indaga en torno a la naturaleza de las relaciones posibles entre el ejercicio de la dominación política y los valores morales. El discurso justificador del poder, de raíces axiológicas, es revisado desde por lo menos tres miradores. El primero es el de Juan Jacobo Rousseau, el segundo el de Michael Foucault y, finalmente, el de Luis Villoro. La idea es encontrar la clave a un viejo y espinoso tema de la moral pública: la (...) legitimidad objetiva de los valores superiores al interés particular. (shrink)

Explícita o implícitamente la relación entre poder y valor ha estado muy presente en la historia del pensamiento filosófico-político. Debido a que el poder,en cualquiera de sus formas, tiende siempre a normar y regular la convivencia y actividad conjunta entre grupos humanos, cualquier reflexión filosófica sobre su naturaleza habrá de cuestionarse, directa o indirectamente, el asunto de su racionalidad ética, de su vínculo con los valoreshumanos.

Explícita o implícitamente la relación entre poder y valor ha estado muy presente en la historia del pensamiento filosófico-político. Debido a que el poder, en cualquiera de sus formas, tiende siempre a normar y regular la convivencia y actividad conjunta entre grupos humanos, cualquier reflexión filosófica sobre su naturaleza habrá de cuestionarse, directa o indirectamente, el asunto de su racionalidad ética, de su vínculo con los valores humanos. Al mismo tiempo, pensar los valores debe conducir, tarde o temprano, a relacionarlos (...) con el poder. En otras palabras, al tema en cuestión que nos ocupa puede (y debe) arribarse tanto desde una reflexión inicialmente centrada en el asunto del poder, como desde el estudio de los valores. Sin embargo ha sido mucho más frecuente la primera línea de desplazamiento reflexivo que la segunda. Tres ejemplos nos servirían para mostrar lo anterior: un pensador clásico de la Modernidad como Rousseau, uno de los representantes ilustres del pensamiento contemporáneo como Foucault y un intelectual mucho más cercano a nuestro contexto como Luis Villoro.

Ontologies are some of the most central constructs in today's large plethora of knowledge technologies, namely in the context of the semantic web. As their coinage indicates, they are direct heirs to the ontological investigations in the long Western philosophical tradition, but it is not easy to make bridges between them. Contemporary ontological commitments often take causality as a central aspect for the ur-segregation of entities, especially in scientific upper ontologies; theories of causality and philosophical ontological investigations often go hand-in-hand, (...) and were essentially inseparable in medieval thought. This constitutes the foundation for a bridge, and this article analyzes the causality-based ontology of the late medieval philosopher Dietrich of Freiberg from the viewpoint of today's upper-ontology engineering. In this bridging attempt, it offers a translation into English of the first part of Dietrich's De origine (abbreviated title) that is a compromise between traditional scholarly translations of medieval Latin philosophical texts and contemporary ontology.

Are philosophy and literature allies or enemies in Jorge Luis Borges's fictions? In this paper, I argue that Borges can satisfy membership in the allies camp because his fictions provide the imaginative scenarios the allies believe are so necessary to this coalition; however, because his stories question philosophy's hold on reality, they can also seem to fall into the enemies camp by countervailing any claim philosophy has on reality and truth; although, ultimately, the manner in which Borges forges an alliance (...) between philosophy and literature will be for reasons not traditionally accepted by those in either the allies or enemies camps. (shrink)

Foundational ontologies, central constructs in ontological investigations and engineering alike, are based on ontological categories. Firstly proposed by Aristotle as the very ur- elements from which the whole of reality can be derived, they are not easy to identify, let alone partition and/or hierarchize; in particular, the question of their number poses serious challenges. The late medieval philosopher Dietrich of Freiberg wrote around 1286 a tutorial that can help us today with this exceedingly difficult task. In this paper, I discuss (...) ontological categories and their importance for foundational ontologies from both the contemporary perspective and the original Aristotelian viewpoint, I provide the translation from the Latin into English of Dietrich's De origine II with an introductory elaboration, and I extract a foundational ontology–that is in fact a single-category one–from this text rooted in Dietrich's specification of types of subjecthood and his conception of intentionality as causal operation.

One of the few points of agreement between most theists and non-theists working on the problem of evil is that the existence of a perfect God is incompatible with the existence of pointless evil. In a series of influential papers, however, Peter van Inwagen has argued that careful attention to the reasoning behind this claim reveals fatal difficulties related to the Sorites Paradox. In this paper, I explain van Inwagen’s appeal to sorites reasoning, distinguish between two different arguments in his (...) work, and argue that they both commit the same so-far-unnoticed mistake. (shrink)

My starting point is what I call the Normative Authority Conception of justification, where S is justified in their belief that p at t (to some degree n) if and only if their believing that p at t is not ruled out by epistemic norms that have normative authority over S at t. With this in mind, this paper develops an account of doxastic justification by first developing an account of the normative authority of epistemic norms. Drawing from work in (...) political philosophy, I argue that (a) the cognitive and evaluative commitments and concerns behind our actual practices of holding each other and ourselves accountable for our beliefs reveal which epistemic norms we have consented to be under, and that (b) it is because we have consented to be under the authority of these norms – by actually holding ourselves and others accountable to them – that they in turn have normative authority over us. By connecting the authority of epistemic norms to the authority we have over ourselves in this way, the resulting account of doxastic justification (i) explains why it can be appropriate to criticize, resent, or sanction someone for having unjustified beliefs, (ii) avoids the phenomena of normative alienation and normative parochialism, and (iii) respects the social and collective nature of epistemic justification. (shrink)

Why should we avoid incoherence? An influential view tells us that incoherent combinations of attitudes are such that it is impossible for all of those attitudes to be simultaneously vindicated by the evidence. But it is not clear whether this view successfully explains what is wrong with certain akratic doxastic states. In this paper I flesh out an alternative response to that question, one according to which the problem with incoherent combinations of attitudes is that it is impossible for all (...) of those attitudes to be simultaneously knowledgeable. This alternative response explains what is wrong with akratic combinations of attitudes using commonly accepted epistemological theses. The paper still shows how this proposal is able to explain the badness of incoherent combinations involving the absence of attitudes, suspended judgment and credence. These explanations deploy the notions of knowledge and being in a position to know, instead of the notion of responding properly to the evidence. Finally, I suggest that this picture can be generalized to the realm of practical rationality as well. (shrink)

Logic arguably plays a role in the normativity of reasoning. In particular, there are plausible norms of belief/disbelief whose antecedents are constituted by claims about what follows from what. But is logic also relevant to the normativity of agnostic attitudes? The question here is whether logical entailment also puts constraints on what kinds of things one can suspend judgment about. In this paper I address that question and I give a positive answer to it. In particular, I advance two logical (...) norms of agnosticism, where the first one allows us to assess situations in which the subject is agnostic about the conclusion of a valid argument and the second one allows us to assess situations in which the subject is agnostic about one of the premises of a valid argument.

On how medieval philosophy is not (only) theology.

"Noé y la Rama de Olivo" de Luis Herrera explora el profundo simbolismo de la rama de olivo en el contexto de la moralidad humana y la renovación existencial. Basándose en la narrativa bíblica del Arca de Noé, Herrera desarrolla una metáfora sobre la paz, la reconciliación y la restauración de la armonía entre la humanidad y el mundo natural. La obra interpreta la rama de olivo no solo como un signo del fin del diluvio, sino como un emblema más (...) profundo de renacimiento ético, que simboliza la oportunidad para que la humanidad reconstruya un mundo más justo y compasivo tras la calamidad. -/- A través de un lente filosófico, Herrera examina la dualidad entre destrucción y creación, planteando que el potencial de crecimiento moral y espiritual surge tras grandes pruebas. El texto cuestiona la naturaleza de la justicia divina y la responsabilidad humana, sugiriendo un llamado a una vigilancia ética constante en un mundo perpetuamente al borde de la autodestrucción. Es una parábola sobre la búsqueda del hombre por la conexión y la reconciliación con lo divino, en un mundo violento lleno de caos, anarquía y la búsqueda antinómica de ideales hedonistas. -/- La obra de Herrera resuena con las preocupaciones contemporáneas sobre la degradación cultural y la fragmentación social, instando a una re-evaluación de nuestra relación con Dios y entre nosotros. La rama de olivo, en esta interpretación, se convierte en un símbolo eterno de esperanza, resiliencia y la búsqueda duradera de una existencia armoniosa. (shrink)

Deontological evidentialism is the claim that S ought to form or maintain S’s beliefs in accordance with S’s evidence. A promising argument for this view turns on the premise that consideration c is a normative reason for S to form or maintain a belief that p only if c is evidence that p is true. In this paper, I discuss the surprising relation between a recently influential argument for this key premise and the principle that ought implies can. I argue (...) that anyone who antecedently accepts or rejects this principle already has a reason to resist either this argument’s premises or its role in support of deontological evidentialism. (shrink)

In this paper, I offer two counterexamples to the so-called ‘Uniqueness Thesis.’ As one of these examples rely on the thesis that it is possible for a justified belief to be based on an inconsistent body of evidence, I also offer reasons for this further thesis. On the assumption that doxastic justification entails propositional justification, the counterexamples seem to work.

In this paper I present reasons for us to accept the hypothesis that suspended judgment has correctness conditions, just like beliefs do. Roughly put, the idea is that suspended judgment about p is correct when both p and ¬p might be true in view of certain facts that characterize the subject’s situation. The reasons to accept that hypothesis are broadly theoretical ones: it adds unifying power to our epistemological theories, it delivers good and conservative consequences, and it allows us to (...) assess processes of reasoning involving attitudes of suspended judgment. (shrink)

Epistemologists take themselves to disagree about whether there are situations where it is rational for one to believe that p and rational for one to believe that one’s evidence does not support p (rational akrasia). The embedded sentence ‘one’s evidence does not support p’ can be interpreted in two ways, however, depending on what the semantic contribution of ‘one’s evidence’ is taken to be. ‘One’s evidence’ might be seen as a sheer indexical or as a descriptive singular term. The first (...) interpretation makes the relevant kind of rational akrasia impossible, whereas the second one makes it possible. But the proposition that is taken to be expressed by ‘one’s evidence does not support p’ by each of these interpretations is not the same. We thus have a rational reconstruction of views that are labeled as being for and against the possibility of rational akrasia according to which they do not really contradict each other. (shrink)

James Sterba has recently argued that the free will defense fails to explain the compossibility of a perfect God and the amount and degree of moral evil that we see. I think he is mistaken about this. I thus find myself in the awkward and unexpected position, as a non-theist myself, of defending the free will defense. In this paper, I will try to show that once we take care to focus on what the free will defense is trying to (...) accomplish, and by what means it tries to do so, we will see that Sterba’s criticism of it misses the mark.

2nd edition. Many-valued logics are those logics that have more than the two classical truth values, to wit, true and false; in fact, they can have from three to infinitely many truth values. This property, together with truth-functionality, provides a powerful formalism to reason in settings where classical logic—as well as other non-classical logics—is of no avail. Indeed, originally motivated by philosophical concerns, these logics soon proved relevant for a plethora of applications ranging from switching theory to cognitive modeling, and (...) they are today in more demand than ever, due to the realization that inconsistency and vagueness in knowledge bases and information processes are not only inevitable and acceptable, but also perhaps welcome. The main modern applications of (any) logic are to be found in the digital computer, and we thus require the practical knowledge how to computerize—which also means automate—decisions (i.e. reasoning) in many-valued logics. This, in turn, necessitates a mathematical foundation for these logics. This book provides both these mathematical foundation and practical knowledge in a rigorous, yet accessible, text, while at the same time situating these logics in the context of the satisfiability problem (SAT) and automated deduction. The main text is complemented with a large selection of exercises, a plus for the reader wishing to not only learn about, but also do something with, many-valued logics. (shrink)

For millennia, knowledge has eluded a precise definition. The industrialization of knowledge (IoK) and the associated proliferation of the so-called knowledge communities in the last few decades caused this state of affairs to deteriorate, namely by creating a trio composed of data, knowledge, and information (DIK) that is not unlike the aporia of the trinity in philosophy. This calls for a general theory of knowledge (ToK) that can work as a foundation for a science of knowledge (SoK) and additionally distinguishes (...) knowledge from both data and information. In this paper, I attempt to sketch this generality via the establishing of both knowledge structures and knowledge systems that can then be adopted/adapted by the diverse communities for the respective knowledge technologies and practices. This is achieved by means of a formal–indeed, mathematical–approach to epistemological matters a.k.a. formal epistemology. The corresponding application focus is on knowledge systems implementable as computer programs. (shrink)

In this editorial, I explain how Paul Feyerabend's Principle of Proliferation is adopted and adapted as a publication model for the Journal of Knowledge Structures and Systems (JKSS). Critical views on the limitations of both non-dynamic publishing models and government- and industry-based models of research are expressed.

W.K. Clifford’s famous 1876 essay The Ethics of Belief contains one of the most memorable lines in the history of philosophy: "it is wrong always, everywhere, and for anyone, to believe anything upon insufficient evidence." The challenge to religious belief stemming from this moralized version of evidentialism is still widely discussed today.

Cet article montre que Fichte développe une originelle conception du langage dans ses Discours à la Nation allemande d’où il ressort non seulement le besoin de retraduire des concepts philosophiques dans un langage populaire comme aussi celui de formuler un langage plus malléable pour la philosophie en tant que telle. Afin d’explorer cette hypothèse, notre propos suivra les étapes suivantes : (i) nous analyserons la conception fichtéenne du rapport entre popularisation et flexibilisation du langage, ce qui nous permettra (ii) d’explorer (...) les raisons systématiques du rapprochement entre langue philosophique et langue populaire et (iii) de saisir précisément la compréhension du rôle philosophique du langage qui en découle.

Paul Silva has recently argued that doxastic justification does not have a basing requirement. An important part of his argument depends on the assumption that doxastic and moral permissibility have a parallel structure. I here reply to Silva's argument by challenging this assumption. I claim that moral permissibility is an agential notion, while doxastic permissibility is not. I then briefly explore the nature of these notions and briefly consider their implications for praise and blame.

Viruses and related infectious genetic parasites are the most abundant biological agents on this planet. They invade all cellular organisms, are key agents in the generation of adaptive and innate immune systems, and drive nearly all regulatory processes within living cells.

This book concerns the nature and the norms of inquiry. It tackles not only philosophical issues regarding what inquiry is, but also issues regarding how it should and should not be executed. Roughly put, inquiry is the activity of searching for the true answers to questions of our interest. But what is the difference between empirical and armchair inquiry? And what are the right and the wrong ways to inquire? Under what conditions should one start inquiring? Which questions are such (...) that one should not inquire into them? The book offers answers to these questions. It argues that competent armchair inquiry only makes explicit what was already implicit--the inquirer already had the answer to her question before inquiring into it, though this was not explicit to her. It also argues that we should avoid inquiring into questions whose answers are unknowable to us, in the instrumental sense of 'should', and that different modes of inquiry are called for, depending on which type of information is available to the subject. These answers are rigorously argued for, and they stem from a unified framework for modeling the activity of inquiry. (shrink)

What I call the Doxastic Puzzle, is the impression that while each of these claims seems true, at least one of them must be false: (a) Claims of the form ‘S ought to have doxastic attitude D towards p at t’ are sometimes true at t, (b) If Φ-ing at t is not within S’s effective control at t, then it is false, at t, that ‘S ought to Φ at t’, (c) For all S, p, and t, having doxastic (...) attitude D towards p at t is not within S’s effective control at t. All three natural replies to the puzzle have been pursued. Some have claimed that doxastic attitudes like believing that p are, in fact, within our effective control, or sufficiently so. Others have claimed that doxastic ought-claims, strictly speaking, are always false. And some have denied that effective control is required for the adequacy of doxastic ought-claims in general. I here pursue and examine a different strategy. In the first part of this paper, I argue that these claims are not only each true but actually not in tension with each other in the first place. Instead of attempting to dispel the puzzle, this solution proposes to evade it instead: to solve it by properly understanding, and by thereby accepting without contradiction, all of its constitutive claims. In the second part of the paper, I argue that the evasive strategy forces us to re-think our understanding of the place of normative reasons in epistemology. More exactly, it seems to come at the cost of one central way of thinking about our reasons for having doxastic attitudes, one where such reasons are good-standing exemplars of normative reasons in general. The evasive strategy, that is, threatens to lead us very quickly to a deflationary picture of epistemic normativity: it rescues normative talk, but sacrifices normative substance. I conclude by explaining why I think this is more consequential than some have made it out to be, and by suggesting that these consequences are welcome nonetheless. (shrink)

Um alinhamento responsável à alguma versão do naturalismo filosófico requer a articulação explicita e cuidadosa de um argumento em sua defesa. Em quatro passos, o texto que segue abaixo expande e examina a validade de um argumento que é frequentemente rascunhado em favor do naturalismo. Como veremos, contudo, a versão do naturalismo que esse argumento nos permite é um pouco diferente dos naturalismos filosóficos mais populares.

Deontological evidentialism is the claim that we ought to form and maintain our beliefs in accordance with our evidence. In this paper, I criticize two arguments in its defense. I begin by discussing Berit Broogard’s use of the distinction between narrow-scope and wide-scope requirements against W.K. Clifford’s moral defense of. I then use this very distinction against a defense of inspired by Stephen Grimm’s more recent claims about the moral source of epistemic normativity. I use this distinction once again to (...) argue that Hilary Kornblith’s criticism of Richard Feldman’s defense of is incomplete. Finally, I argue that Feldman’s defense is insensitive to the relation between normative requirements and privileged values: values that have normative authority over us. (shrink)

To most of us – believers and non-believers alike – the possibility of a perfect God co-existing with the kinds of evil that we see calls out for explanation. It is unsurprising, therefore, that the belief that God must have justifying reasons for allowing all the evil that we see has been a perennial feature of theistic thought. Recently, however, a growing number of authors have argued that the existence of a perfect God is compatible with the existence of gratuitous (...) evil. Given powerful, millenia-long sensibilities about power and love and justice, it isn’t hard to find that suggestion simply incredible. Nonetheless, in this paper I will argue that the most prominent theistic alternatives to what has seemed incredible to most of us throughout most of history are themselves patently unacceptable for the theist as well. On any of the most widely accepted accounts of how God could have justifying reasons for permitting some evils, God’s existence means that we have justifying reasons for perpetrating and allowing every evil that we see. That's hard to swallow too. If I’m right about all of this, then two competing outcomes seem to present themselves as a possible result. On the one hand, for the theist, the apparently outrageous suggestion that the existence of a perfect God is compatible with gratuitous evil no longer looks like it faces a formidable, hard-to-resist alternative. On the other hand, some like me might think that my arguments go no distance at all towards dispelling the incredibility of the gratuitous evil nouvelle vague. On this line, theism may seem now to be between the rock and the hard place: it seems hard to make sense of the existence of a perfect God whether or not He has justifying reasons for allowing all the evil that we see.

Aesthetic subjectivism takes the truth of aesthetic judgments to be relative to the individual making that judgment. Despite widespread suspicion, however, this does not mean that one cannot be wrong about such judgments. Accordingly, this does not mean that one cannot gain higher-order evidence of error and fallibility that bears on the rationality of the aesthetic judgment in question. In this paper, we explain and explore these issues in some detail.

This paper introduces pragmatic hypotheses and relates this concept to the spiral of scientific evolution. Previous works determined a characterization of logically consistent statistical hypothesis tests and showed that the modal operators obtained from this test can be represented in the hexagon of oppositions. However, despite the importance of precise hypothesis in science, they cannot be accepted by logically consistent tests. Here, we show that this dilemma can be overcome by the use of pragmatic versions of precise hypotheses. These pragmatic (...) versions allow a level of imprecision in the hypothesis that is small relative to other experimental conditions. The introduction of pragmatic hypotheses allows the evolution of scientific theories based on statistical hypothesis testing to be interpreted using the narratological structure of hexagonal spirals, as defined by Pierre Gallais.

Epistemologists often describe subjects as being capable of adopting a third kind of categorical doxastic stance regarding whether something is the case, besides belief and disbelief. They deploy a variety of idioms in order to ascribe that stance. In this paper, I flesh out the properties that the third kind of categorical stance is supposed to have and start searching for the best ways to ascribe it. The idioms ‘suspends judgment about whether’ and ‘is agnostic about whether’, among others, are (...) found to be unfit to play the desired role. In the end, I suggest that ‘is in doubt as to whether’ is our best choice among the alternatives surveyed here. (shrink)

Let T be any logical truth. Does the subject know that T (any random subject)? It is not rational for any subject to believe that they don’t, whoever they are. Similarly, it is not rational for them to believe that their evidence doesn’t support T, and it is not even rational for them to believe that they don’t believe that T. It is not rational for anyone anywhere at any time to believe that they don’t know that T. Such are (...) the conclusions arrived at in this paper. (shrink)

The letters present us a comparison between England and France. In this parallel we shall present how Voltaire was concerned in evaluate a high standard of taste and refinements.

We shall present in Voltaire the eminence of (...) modernity in taste, refinements and on liberty of enjoying the ecstasies of a cosmopolitan life fulfilled with entertainments and luxury. We shall present how Voltaire fought against barbarism in benefit of civilization and some how against religiosity in benefit of an ethic hedonism. (shrink)

The aim of this article is to advance the idea according to which the Cartesian Cogito, the ground of modern philosophy and the source of the notion of thinking subject, is tributary of a certain method whose legitimation is grounded in western history. According to this hypothesis, there is a certain tool that plays a fundamental role in the production of this new philosophical notion: the dream. The argument will be developed in four parts. We will first proceed to (i) (...) an analysis of the role of the hypothesis of the dream in the formulation of the notion of res cogitans, what will bring us to (ii) an exploration of the conception of private world supposed by such a hypothesis so as to (iii) clarify the specificity of the Cartesian notion of knowledge, a knowledge that must be acquirable in a dream; in conclusion (iv) we will indicate in a schematic way the historic-cultural anchor of the Cartesian dream where the subject is originated.

In Who's Afraid of Idealism? the philosophical concept of idealism, the extent to which reality is mind-made, is examined in new light. Author Luis M. Augusto explores epistemological idealism, at the source of all other kinds of idealism, from the viewpoints of Immanuel Kant and Friedrich Nietzsche, two philosophers who spent a large part of their lives denigrating the very concept. Working from Kant and Nietzsche's viewpoints that idealism was a scandal to philosophy and the cause of nihilism, Augusto evaluates (...) these philosophers and their role in shaping epistemological idealism. Using textual evidence from their writings and their reactions to western philosophers such as Plato, Descartes, and Hegel, Who's Afraid of Idealism? argues that in fact Kant and Nietzsche were really idealists at heart. In accessible prose, this text puts forward a theory that goes against current scholarly opinion, and even Kant and Nietzsche's opinions of themselves. (shrink)

Recent investigations surprisingly indicate that single RNA "stem-loops" operate solely by chemical laws that act without selective forces, and in contrast, self-ligated consortia of RNA stem-loops operate by biological selection. To understand consortial RNA selection, the concept of single quasi-species and its mutant spectra as drivers of RNA variation and evolution is rethought here. Instead, we evaluate the current RNA world scenario in which consortia of cooperating RNA stem-loops are the basic players. We thus redefine quasispecies as RNA quasispecies consortia (...) and argue that it has essential behavioral motifs that are relevant to the inherent variation, evolution and diversity in biology. We propose that qs-c is an especially innovative force. We apply qs-c thinking to RNA stem-loops and evaluate how it yields altered bulges and loops in the stem-loop regions, not as errors, but as a natural capability to generate diversity. This basic competence-not error-opens a variety of combinatorial possibilities which may alter and create new biological interactions, identities and newly emerged self identity functions. Thus RNA stem-loops typically operate as cooperative modules, like members of social groups. From such qs-c of stem-loop groups we can trace a variety of RNA secondary structures such as ribozymes, viroids, viruses, mobile genetic elements as abundant infection derived agents that provide the stem-loop societies of small and long non-coding RNAs.

Genera, typically hand-in-hand with their branching species, are essential elements of vocabulary-based information constructs, in particular scientific taxonomies. Should they also feature in formal ontologies, the highest of such constructs? I argue in this article that the answer is “Yes” and that the question posed in its title also has a Yes-answer: The way medieval ontologists sliced up the world into genera does matter to formal ontology. More specifically, the way Dietrich of Freiberg, a Latin scholastic, conceived and applied strictly (...) generic criteria to slice up the world into its entities can provide some guidelines to the field of formal ontology with respect to not only its contents, but also its scope. In particular, Dietrich's information criterion plays here a central role. (shrink)

This article advances the hypothesis that the Fichtean enterprise of grounding all possible experience in a fundamental principle has to fail in order to succeed one of its most important tasks: reformulating the very idea of subjectivity. In order to ground this hypothesis, the paper will be divided in four parts: (i) the first one will analyze the starting point of the work where Fichte lays the foundations of his philosophical project (Grundlage der gesamten Wissenschaftslehre) so as to show that (...) its first principle contains a fundamental ambiguity. We will then (ii) suggest that this very ambiguity reveals itself in the Anstoß, the conceptual tool through which Fichte intends to get rid of the Kantian notion of thing-in- itself. In a third moment (iii), we will explore the effects of this abandonment of the thing-in-itself on the relation between the finite and the infinite, what will bring us to the notion of failure. Finally (iv), we will propose to interpret this failure as a positive driving force of a permanent calling into question of the subject and its language. (shrink)

This paper explores the contrast between two meanings of thinking: (i) one implied by the Cartesian and Kantian philosophy, the two thinkers that have arguably the deepest influence on the constellation of Western philosophical problems and (ii) another implied by the philosophical-anthropological project of the Brazilian anthropologist Eduardo Viveiros de Castro. The thesis here defended is that, in the Cartesian and Kantian philosophy, thinking is related to ruling and legislating over the experience through concepts, while in Viveiros de Castros' theoretical (...) enterprise, thinking is rather to explore the limits of conceptual constructions when confronted with the experience of alterity.
