My hypothesis is that the cognitive challenge posed by death might have had a co-evolutionary role in the development of linguistic faculties. First, I claim that mirror neurons, which enable us to understand others’ actions and emotions, not only activate when we directly observe someone, but can also be triggered by language: words make us feel bodily sensations. Second, I argue that the death of another individual cannot be understood by virtue of the mirror neuron mechanism, since the dead provide (...) no neural pattern for mirroring: this cognitive task requires symbolic thought, which in turn involves emotions. Third, I describe the symbolic leap of the human species as a cognitive detachment from the here and now, allowing displaced reference: through symbols the human mind can refer to what is absent, possible, or even impossible (like the presence of a dead person). Such a detachment has had a huge adaptive impact: adopting a coevolutionary standpoint can help explain why language is as effective as environmental inputs in order to stimulate our bodily experience. In the end I suggest a further coevolutionary reversal : if language is necessary to understand the death of the other, it might also be true that the peculiar cognitive problem posed by the death of the other (the corpse is present, but the other is absent) has contributed to the crucial transition from an indexical sign system to the symbolic level, i.e., the cognitive detachment . Death and language, as Heidegger claimed, have an essential relation for humans, both from an evolutionary and a phenomenological perspective: they have shaped the symbolic consciousness that make us conceive of them.

What is the difference between the discriminations made by a home appliance able to distinguish salt from sugar, and my sensations of salty and sweet? It is never taken into consideration that, in contrast to the appliance, I can have offline sensations, i.e., phenomenal experiences in the absence of direct environmental stimuli, mainly evoked by words occurring into thought, conversation, reading, etc. If we put this detachment stimuli/sensations in relation with the correlative detachment signs/referents inaugurated by the cognitive revolution of (...) symbolic language , we might rethink the role played by language in our phenomenal experience as a whole. Qualia can be defined as forms of relationship between organisms and environment, given that human environment is extended to the linguistic dimension, and that the latter has ignited a coevolutionary process with human cognition. The very same properties we attribute to qualia, even when conceiving of them as pre-linguistic phenomenal traits, rely on the cognitive resources that language has made available. The substantialist notion of qualia, I argue, is formed by an online sensation on which the focus shifts from the perceived object to the sensory quality by virtue of linguistic modes of thinking, which are systematically neglected.

Plural Logic is an extension of First-Order Logic which has, as well as singular terms and quantifiers, their plural counterparts. Analogously, Higher-Level Plural Logic is an extension of Plural Logic which has, as well as plural terms and quantifiers, higher-level plural ones. Roughly speaking, higher-level plurals stand to plurals like plurals stand to singulars; they are pluralised plurals. Allegedly, Higher-Level Plural Logic enjoys the expressive power of a simple type theory while committing us to nothing more than the austere ontology (...) of First-Order Logic. Were this true, Higher-Level Plural Logic would be a useful tool, with various applications in philosophy and linguistics. However, while the notions of plural reference and quantification enjoy widespread acceptance today, their higher-level counterparts have been received with a lot of scepticism. In this paper, I argue for the legitimacy of Higher-Level Plural Logic by providing evidence to the effect that natural languages contain higher-level plural expressions and showing that it is likely that they do so in an indispensable manner. Since the arguments I put forward are of the same sort advocates of Plural Logic have employed to defend their position, I conclude that the commonly held view that Plural Logic is legitimate, but not so its higher-level plural extensions is untenable.

Sets are central to mathematics and its foundations, but what are they? In this book Luca Incurvati provides a detailed examination of all the major conceptions of set and discusses their virtues and shortcomings, as well as introducing the fundamentals of the alternative set theories with which these conceptions are associated. He shows that the conceptual landscape includes not only the naïve and iterative conceptions but also the limitation of size conception, the definite conception, the stratified conception and the (...) graph conception. In addition, he presents a novel, minimalist account of the iterative conception which does not require the existence of a relation of metaphysical dependence between a set and its members. His book will be of interest to researchers and advanced students in logic and the philosophy of mathematics. (shrink)

Translation of passages of Aristotle's De Anima into Portuguese. The passages are these: I.1, I.4 (the 'Rylean passage'); II.1-6; III.1-8. The translation is preliminary.

Translation of Aristotle's Posterior Analytics I into Portuguese, with a few notes, experimental glossary and introduction. The translation, which was made at 2003/4, was preliminary and its publication was intended to provide a didactic tool for courses as well as a provisional resource in research seminars. It needs some revision. I am currently working (slowly...) on the revision of the translation and a new revised one will surely appear at some point.

In Posterior Analytics 71b9 12, we find Aristotle’s definition of scientific knowledge. The definiens is taken to have only two informative parts: scientific knowledge must be knowledge of the cause and its object must be necessary. However, there is also a contrast between the definiendum and a sophistic way of knowing, which is marked by the expression “kata sumbebekos”. Not much attention has been paid to this contrast. In this paper, I discuss Aristotle’s definition paying due attention to this contrast (...) and to the way it interacts with the two conditions presented in the definiens. I claim that the “necessity” condition ammounts to explanatory appropriateness of the cause. (shrink)

In this paper, we develop an impure somatic theory of emotion, according to which emotions are constituted by the integration of bodily perceptions with representations of external objects, events, or states of affairs. We put forward our theory by contrasting it with Prinz's pure somatic theory, according to which emotions are entirely constituted by bodily perceptions. After illustrating Prinz's theory and discussing the evidence in its favor, we show that it is beset by serious problems—i.e., it gets the neural correlates (...) of emotion wrong, it isn't able to distinguish emotions from bodily perceptions that aren't emotions, it cannot account for emotions being directed towards particular objects, and it mischaracterizes emotion phenomenology. We argue that our theory accounts for the empirical evidence considered by Prinz and solves the problems faced by his theory. In particular, we maintain that our theory gives a unified and principled account of the relation between emotions and bodily perceptions, the intentionality of emotions, and emotion phenomenology.

The introduction of and the commitment to evidence-based nursing in all care settings have led to a rapid increase of intervention and outcome-based research programs. Yet, the topics of nursing research are not only affected by interventions and outcomes but also affected by the concept of caring derived from humanistic philosophy. Considering this twofold orientation of nursing science, nuanced ethical regulations for nursing research programs are called for. In addition to the different research approaches, further arguments for ethical regulations are (...) as follows: first, the different degrees of contextualization and the variety of participation models regarding the target groups; second, the capacities and opportunities of participants; and third, the caring relationship between nurses and research subjects. To capture these special features of nursing science, four approaches to fill the gaps in existing ethical regulations for nursing research are proposed: (a) process orientation, (b) community orientation, (c) context orientation, and (d) relation orientation.

Cuando hablamos de iconos nos referimos a representaciones que producen un cierto impacto en nosotros aunque no sean perfectas; del icono se esperan armonía, belleza, simplicidad. Cuando el icono no es una imagen sino una persona humana, se convierte en referente: observamos aspectos de su personalidad con los que nos identificamos aunque nos coincidan exactamente con los nuestros. A lo largo de la historia de la ciencia, las mujeres han sido iconos referenciales fundamentalmente por dos cosas, su calidad humana y (...) su excelencia científica. (shrink)

Este escrito pretende examinar el papel de la estética en el pensamiento de Schiller y Schelling en 1795 para rastrear el modo en que el pensamiento estético comienza a constituirse como un camino desde el que afrontar la problemática de la libertad planteada por la modernidad y, en especial, por la filosofía práctica de Kant. En el primer apartado se tratará de aclarar el sentido en el que la reflexión estética de ambos autores en 1795 no se puede disociar de (...) la problemática servida por la filosofía kantiana. En primer lugar intentaré mostrar las razones por las que las premisas mismas del sistema crítico hacen necesaria la Crítica del Juicio, cuya primera parte, como es sabido, constituye precisamente una ¿crítica del juicio estético¿ y, desde aquí, defenderé que la obra se hace cargo de cierta ambivalencia inherente al kantismo y que, precisamente por ello, expresa del modo más perspicuo el problema que plantea el concepto kantiano, formal, de libertad. Con ello se insiste evidentemente en la relevancia de esta obra para la primera recepción de Kant en general, esto es, para el primer Idealismo postkantiano en tanto que preocupado por elevarse a la verdad del espíritu kantiano, pero, sobre todo, se comenzarán a iluminar las razones por las que la orientación estética del pensamiento, orientación que en 1795 exploran tanto Schiller como Schelling, podrá considerarse un camino privilegiado de cara tanto a la ¿recuperación¿ de la consistencia del kantismo como a la elaboración de un concepto satisfactorio de libertad. Es decir, se intentará fundamentar así, aun cuando sólo sea indirectamente, que la conexión de la ética, de la filosofía práctica, con la estética resulta prometedora aun desde una óptica estrictamente kantiana. Pero el núcleo de este trabajo se desarrollará en los apartados segundo y tercero donde, partiendo de este suelo común compartido por Schiller y Schelling, se examinarán las diferencias entre los modos en que la reflexión estética de cada uno responde a la problemática planteada por el kantismo. En relación a esto último será fundamental determinar si sus respuestas, en tanto que soluciones, realmente se mantienen fieles a la complejidad que nace de la ambivalencia del espíritu kantiano o si, antes bien, pagan el precio de optar por uno sólo de los hilos que tejen el sistema crítico.

Taking the Critique of Judgement for an answer to the problem raised by the kantian dualisms, I offer a reading of this work according to which in the part devoted to the teleological judgement Kant practices a Hegelian way of resolution, whereas, in the “critique of the aesthetic judgement”, he thinks the relation between the opposites of such dualisms in a new way that opens up the possibility of a dialectical thought rid of the absolutness of the Hegelian reason.

Translation of Aristotle's Physics I-II into Portuguese, with commentaries. Tradução para o português dos livros I e II da Física de Aristóteles, com comentários.

I discuss what Aristotle means when he say that scientific demonstration must proceed from necessary principles. I argue that, for Aristotle, scientific demonstration should not be reduced to sound deduction with necessary premises. Scientific demonstration ultimately depends on the fully appropriate explanatory factor for a given explanandum. This explanatory factor is what makes the explanandum what it is. Consequently, this factor is also unique. When Aristotle says that demonstration must proceed from necessary principles, he means that each demonstration requires the (...) principle that is the necessary one for the fully appropriate explanation of its explanandum. This picture also provides a key to understand Aristotle's thesis that scientific explanation depends on essences: it is the essence of the attribute to be explained that should be stated as the fully appropriate explanatory factor.

Experiences like pains, pleasures, and emotions have affective phenomenal character: they feel pleasant or unpleasant. Imperativism proposes to explain affective phenomenal character by appeal to imperative content, a kind of intentional content that directs rather than describes. We argue that imperativism is on the right track, but has been developed in the wrong way. There are two varieties of imperativism on the market: first-order and higher-order. We show that neither is successful, and offer in their place a new theory: reflexive (...) imperativism. Our proposal is that an experience P feels pleasant in virtue of being constituted by a Command with reflexive imperative content, while an experience U feels unpleasant in virtue of being constituted by a Command with reflexive imperative content : More of P!Less of U! If you need a slogan: experiences have affective phenomenal character in virtue of commanding us Get more of me! Get less of me! (shrink)

Analyzing geometric properties of high-dimensional loss functions, such as local curvature and the existence of other optima around a certain point in loss space, can help provide a better understanding of the interplay between neural network structure, implementation attributes, and learning performance. In this work, we combine concepts from high-dimensional probability and differential geometry to study how curvature properties in lower-dimensional loss representations depend on those in the original loss space. We show that saddle points in the original space are (...) rarely correctly identified as such in expected lower-dimensional representations if random projections are used. The principal curvature in the expected lower-dimensional representation is proportional to the mean curvature in the original loss space. Hence, the mean curvature in the original loss space determines if saddle points appear, on average, as either minima, maxima, or almost flat regions. We use the connection between expected curvature in random projections and mean curvature in the original space (i.e., the normalized Hessian trace) to compute Hutchinson-type trace estimates without calculating Hessian-vector products as in the original Hutchinson method. Because random projections are not suitable to correctly identify saddle information, we propose to study projections along dominant Hessian directions that are associated with the largest and smallest principal curvatures. We connect our findings to the ongoing debate on loss landscape flatness and generalizability. Finally, for different common image classifiers and a function approximator, we show and compare random and Hessian projections of loss landscapes with up to about 7×10^6 parameters. (shrink)

Aristotle contrasts episteme and doxa through the key notions of universal and necessary. These notions have played a central role in Aristotle’s characterization of scientific knowledge in the previous chapters of APo. They are not spelled out in APo I.33, but work as a sort of reminder that packs an adequate characterization of scientific knowledge and thereby gives a highly specified context for Aristotle’s contrast between episteme and doxa. I will try to show that this context introduces a contrast in (...) terms of explanatory claims: on the one hand, episteme covers those claims which capture explanatory connections that are universal and necessary and thereby deliver scientific understanding; on the other hand, doxa covers the explanatory attempts that fail at doing so.

During the last decades the special literature has paid relatively much attention to the problematic of speech acts. However, in Slovakia it still remains underdeve-loped. Therefore the author decided to examine it from the points of view of its establishment, gradual development and interactional communication.

Further, it gives a more detailed analysis of the theory of the founders of the speech acts theory , comparing their main ideas with (...) those of other philosophers and linguists. (shrink)

I examine Aristotle’s definition of scientific knowledge in Posterior Analytics 71b 9-12 and try to understand how it relates to the sophistical way of knowing and to "kata sumbebekos knowledge". I claim that scientific knowledge of p requires knowing p by its appropriate cause, and that this appropriate cause is a universal (katholou) in the restricted sense Aristotle proposes in 73b 26-27 ff., i.e., an attribute coextensive with the subject (an extensional feature) and predicated of the subject in itself (an (...) intensional feature). Kata sumbebekos knowledge, on the other hand, can occur even when the predicate of a conclusion is coextensive with its subject and is proved by a convertible meson which is not the most appropriate from an explanatory standpoint.

I discuss the exact meaning of the thesis according to which the object of scientific knowledge is necessary. The thesis is expressed by Aristotle in the Posterior Analytics, in his definition of scientific knowledge. The traditional interpretation understands this definition as depending on two parallel and independent requirements, the causality requirement and the necessity requirement. Against this interpretation, I try to show, through the examination of several passages that refer to the definition of scientific knowledge, that the necessity requirement specifies (...) more exactly the causality requirement: what cannot be otherwise is the explanatory relation between the explanandum and the cause by which it is what it is.

This book uses mathematical models of language to explain why there are certain gaps in language: things that we might expect to be able to say but can't. For instance, why can we say I ran for five minutes but not *I ran to the store for five minutes? Why is five pounds of books acceptable, but *five pounds of book not acceptable? What prevents us from saying *sixty degrees of water to express the temperature of the water in a (...) swimming pool when sixty inches of water can express its depth? And why can we not say *all the ants in my kitchen are numerous? The constraints on these constructions involve concepts that are generally studied separately: aspect, plural and mass reference, measurement, and distributivity. In this book, Lucas Champollion provides a unified perspective on these domains, connects them formally within the framework of algebraic semantics and mereology, and uses this connection to transfer insights across unrelated bodies of literature and formulate a single constraint that explains each of the judgments above.

El objetivo de este artículo es ofrecer, al hilo de un análisis del texto de la Fenomenologíadel Espíritu que comenta la Antígona de Sófocles, una interpretación del concepto hegeliano de acciónque pone en cuestión la tesis, defendida habitualmente, según la cual Hegel habría pretendido que elconflicto trágico resulta superado por la acción moderna.Ese texto revela que la acción, que comparece ahí como principio absoluto, posee sin embargo unaestructura quebrada y paradójica: necesariamente presupone y niega una instancia en sí, inmediata ysustantiva (...) que, finalmente, oculta la negatividad de la muerte. En la medida en que esa vinculación ala sustancia se demuestra así consustancial a la acción, el trabajo concluye, frente a otras lecturas, que,aun cuando la historia del espíritu haya dejado atrás la “sustancia ética” antigua, la acción nopuede liberarse para Hegel del carácter trágico. Por último, defiende el sentido en el que precisamenteesta condición trágica la determina a la vez como destructiva y productiva, capaz de abrir la historia. (shrink)

Mindreading (or folk psychology, Theory of Mind, mentalizing) is the capacity to represent and reason about others’ mental states. The Simulation Theory (ST) is one of the main approaches to mindreading. ST draws on the common-sense idea that we represent and reason about others’ mental states by putting ourselves in their shoes. More precisely, we typically arrive at representing others’ mental states by simulating their mental states in our own mind. This entry offers a detailed analysis of ST, considers theoretical (...) arguments and empirical data in favour of and against it, discusses its philosophical implications, and illustrates some alternatives to it.

I discuss the methodological passage in the begin- ning of Ethica Eudemia I.6 (1216b26-35), which has received attention in connection with Aristotle’s notion of dialectic and his methodology in Ethics. My central focus is not to discuss whether Aristotle is prescribing and using what has been called the method of endoxa. I will focus on how this passage coheres with the remaining parts of the same chapter, which also are advancing methodological remarks. My claim is that the meth- od of (...) Ethica Eudemia I.6 is in agreement with many features of Aristotle’s theory of explanation as presented in the Posterior Analytics: Aristotle’s main concern is a warning against misuses of explanatory arguments.

This paper examines Aristotle’s notion of priority with the specific aim of capturing the sort of priority that characterizes the primacy of substances in his metaphysics. I reject the traditional interpretation, which understands the ontological priority of substances in terms of independent existence. But there are rather two sorts of priority: the ontological priority of substances should be understood in terms of completeness, whereas the ontological priority of “substances-of-something” (the essences) is a causal-explanatory priority. Furthermore, an important piece of Aristotle’s (...) argument against Platonism is that these two sorts of priority – namely, the completeness priority and the causal-explanatory priority – should be kept distinct.

This is an introductory handbook for some of the main themes around the notion of predication in Aristotle.

This paper discusses some issues concerning the definition of moral virtue in Nicomachean Ethics 1106b 36- 1107a 2. It is reasonable to expect from a definition the complete enumeration of the relevant features of its definiendum, but the definition of moral virtue seems to fail in doing this task. One might be tempted to infer that this definition is intended by Aristotle as a mere preliminary account that should be replaced by a more precise one. The context of the argument (...) Aristotle develops in Book II of his NE give us some help. I argue that the definition of moral virtue, once considered in the light of its context, is far from being an incomplete and provisional account: it rather introduces coherently the same notion of moral virtue that Aristotle employs in other texts (as in Nicomachean Ethics VI 13). My main proposal is that the way in which "hexis" is understood in the context of previous chapters allows Aristotle to encode in it the notion of an ability to do the right things regularly. Thus, moral virtue is a "hexis prohairetike etc.", but the ability to do the right things regularly is already encoded in the occurrence of "hexis" in the definiens account of moral virtue, as if Aristotle meant "hexis [praktike] prohairetike".

Joint attention customarily refers to the coordinated focus of attention between two or more individuals on a common object or event, where it is mutually “open” to all attenders that they are so engaged. We identify two broad approaches to analyse joint attention, one in terms of cognitive notions like common knowledge and common awareness, and one according to which joint attention is fundamentally a primitive phenomenon of sensory experience. John Campbell’s relational theory is a prominent representative of the latter (...) approach, and the main focus of this paper. We argue that Campbell’s theory is problematic for a variety of reasons, through which runs a common thread: most of the problems that the theory is faced with arise from the relational view of perception that he endorses, and, more generally, they suggest that perceptual experience is not sufficient for an analysis of joint attention.

This paper discusses the contrast between scientific knowledge and opinion as it is presented by Aristotle in Posterior Analytics A.33. Aristotle's contrast is formulated in terms of understanding or not understanding some "necessary items". I claim that the contrast can only be understood in terms of explanatory relevance. The "necessary items" are middle terms (or explanatory factors) that are necessary for the fully appropriate explanation. This approach gives a coherent interpretation of each step in the chapter.
