The paper deals with the beginning and the main properties of the science of nature (he peri physeos historiê). According to Themistius (DK 12 A 7), the founder of this kind of Ionic philosophy is Anaximander of Miletus because he was the first who wrote about nature (especially a cosmography and a cosmogony) and developed three main principles of nature: 1. Nature has a mathematical structure (Arist. De coelo I3 295b10-14.32); 2. nature has a physical structure (DK 12 A 10-11); (...) and 3. nature follows natural laws (DK 12 A 9). The origin of this introduction lies in the prolongation of primitive expectations of constancy. It is especially argued that the shift from mythos to logos is characterized by the depersonalization of nature and the introduction of theoretical terms. In fact, the "apeiron" of Anaximander seems to be something similar to a theoretical term, because Anaximander seems to have realized that the explanans of nature cannot be one of its explananda like water (Thales) or air (Anaximenes).

Detendo-se na questão do simbólico, que, precedendo e excedendo a razão, se impõe como fundamento da condição de uma existência que não tende a dialogar senão com a possibilidade, o artigo em questão investiga a sua emergência através das formas que se inter-relacionam na constitutividade da realidade (a saber, a linguagem, o mito, a religião), recorrendo à noção do sistema proposto pela leitura de Ernst Cassirer, que instaura um processo que do pertencimento à espécie animal à fala, do mythos ao (...) lógos, acena com a experiência da autoconstrução humana, convergindo para possibilitar, em suma, antes do que o conhecimento do Ser, a sua criação.

Il saggio tratta della figura di Empedocle – pensiero e uomo insieme, per­fettamente coerenti uno con l’altro – considerandolo come un pensatore di confine, un symbolon, nel quale s’incontrano senza fondersi e senza pre­varicarsi due universi, quello del mythos e quello del logos, con tutte le lo­ro rispettive e complesse implicazioni. Tutto ciò è necessario per com­prendere la lettura che Empedocle presenta della physis, processo naturale e modo di essere ad un tempo, che si esplicita nelle quattro radici – acqua, (...) aria, terra e fuoco – che costituiscono il tutto, relazionandosi attraverso Philia e Neikos, le due forze contrarie e polari che tengono insieme l’es­sere uno e molteplice. The essay deals with the Empedocle’s figure – both man and mind per­fectly acting consistently each other – considering him like a border thin­ker, a symbolon, in wich two universes, one of the mythos and one of the logos with their respective and complex implications, meet without mixing and without prevaricating. All this is necessary to understand the Empe­docle’s reading about the physis, either a natural process or a way of being at the same time expressing itself in four roots – water, air, land and fire – which consisted the whole reporting each other through Philia and Neikos, two opposite and polar forces that keep together the one and various being.

Nel presente contributo è nostra intenzione sondare un binomio che appare fondamentale in funzione dialogica interculturale e interreligiosa, ossia la relazione tra logos e mythos, principalmente in vista dell’incontro tra cristianesimo e tradizione induista. È nostra convinzione che le forme complementari di «teo-logia» e «teo-mythia» possa essere esplorato con frutto, tanto in funzione specifica dell’incontro con la tradizione induista, quanto per una più ampia e profonda inculturazione del vangelo.

There is a difference between the tasks of interpreting Sextus Empiricus and contesting his arguments. Usually, one does the latter relying on some version of the former. Though this seems obvious, it is easy to make mistakes in this endeavor. From this point, I draw two basic recommendations which we should follow, lest we take Sextus to hold implausible positions regarding his Five Modes. However, these recommendations lead us to interpret Sextus’ Pyrrhonism as a limited skepticism. In the final section, (...) as I suggest a counter-example to this commitment, I reconsider the notion of infinite (apeiron) in the Five Modes to better explain interpretation and criticism of Sextus’ arguments.

The advent of logical positivism contributed to the sharp definitional demarcation between what we consider mythical (mythos) and what we take to be a true account (logos). This essay attempts to go back to one of the sources of such a supposed distinction. By analyzing the Gorgias, I will show that even Plato did not make such a distinction. In fact, Plato even constructed a theory of justice that made use of myth as its medium. The Platonic Myth in the (...) Gorgias was used as true logos in order to justify Socrates’ use of the myth as the paradigm of a life that is philosophical in contrast to that of his accusers who espoused mere sophistry. By using the concept of historia in relation with the concept of mythos, Plato regarded the futuristic afterlife in the myth as a sufficient condition to live a just life. This sufficient condition exemplified by the Myth in the Gorgias is a measuring rod by which we can compare our present system of justice. (shrink)

In this essay, we draw on John Haugeland’s work in order to argue that Burge is wrong to think that exercises of perceptual constancy mechanisms suffice for perceptual representation. Although Haugeland did not live to read or respond to Burge’s Origins of Objectivity, we think that his work contains resources that can be developed into a critique of the very foundation of Burge’s approach. Specifically, we identify two related problems for Burge. First, if (what Burge calls) mere sensory responses are (...) not representational, then neither are exercises of constancy mechanisms, since the differences between them do not suffice to imply that one is representational and the other is not. Second, taken by themselves, exercises of constancy mechanisms are only derivatively representational, so merely understanding how they work is not sufficient for understanding what is required for something, in itself, to be representational (and thereby provide a full solution to the problem of perceptual representation).

This article shows that in 1.4.2.15-24 of the Treatise of Human Nature, Hume presents his own position on objects, which is to be distinguished from both the vulgar and philosophical conception of objects. Here, Hume argues that objects that are effectively imagined to have a “perfect identity” are imagined due to the constancy and coherence of our perceptions (what we may call ‘level 1 constancy and coherence’). In particular, we imagine that objects cause such perceptions, via what I call ‘indirect (...) causation.’ In virtue of imagining ideas of objects that have a perfect identity, our perceptions seem to be even more constant and coherent (what we may call ‘level 2 constancy and coherence’). Thus, in addition to seeing that Hume is presenting his own position on objects in this section of the Treatise, we see that he is working with a previously unrecognized kind of causation, i.e., indirect causation, and that he has two kinds of constancy and coherence in mind: level 1 and level 2.

All representationalists maintain that there is a necessary connection between an experience’s phenomenal character and intentional content; but there is a disagreement amongst representationalists regarding the nature of those intentional contents that are necessarily connected to phenomenal character. Russellian representationalists maintain that the relevant contents are composed of objects and/or properties, while Fregean representationalists maintain that the relevant contents are composed of modes of presentation of objects and properties. According to Fregean representationalists such as David Chalmers and Brad Thompson, the (...) Fregean variety of the view is preferable to the Russellian variety because the former can accommodate purported counterexamples involving spectrum inversion without illusion and colour constancy while the latter cannot. I maintain that colour constancy poses a special problem for the Fregean theory in that the features of the theory that enable it handle spectrum inversion without illusion cannot be extended to handle colour constancy. I consider the two most plausible proposals regarding how the Fregean view might be developed in order to handle colour constancy—one of which has recently been defended by Thompson —and argue that neither is adequate. I conclude that Fregean representationalism is no more able to accommodate colour constancy than is Russellian representationalism and, as such, ought to be rejected. (shrink)

I argue for the following claims: (1) A core Husserlian account of perceptual constancy needs to be given in terms of indicative future-oriented conditionals but can be complemented by a counterfactual account; (2) thus conceived, constancy is a necessary aspect of content. I speak about a “core Husserlian” account so as to capture certain ideas that Michael Madary has presented as the core of Edmund Husserl's approach to perceptual constancy, viz., that “perception is partly constituted by the continuous interplay of (...) intention and fulfilment” and that this “gives us a way to understand the relationship between different appearances of the same object” (See Madary, M. (2012) “Husserl on Perceptual Constancy.” European Journal of Philosophy 20(1): 145–165.). I take myself to be developing, and perhaps correcting, Madary's view as I discuss the role of the core Husserlian ideas, and counterfactuals, in accounting for shape and color constancy, respectively. I bridge constancy and fulfilment-conditional content by appealing to the Husserlian notion of constitution, which captures the process in which objectivity and, correlatively, intentional experience, are built up in the experiential flow.

Naive observers viewed a sequence of colored Mondrian patterns, simulated on a color monitor. Each pattern was presented twice in succession, first under one daylight illuminant with a correlated color temperature of either 16,000 or 4,000 K and then under the other, to test for color constancy. The observers compared the central square of the pattern across illuminants, either rating it for sameness of material appearance or sameness of hue and saturation or judging an objective property—that is, whether its change (...) of color originated from a change in material or only from a change in illumination. Average color constancy indices were high for material appearance ratings and binary judgments of origin and low for hue–saturation ratings. Individuals’ performance varied, but judgments of material and of hue and saturation remained demarcated. Observers seem able to separate phenomenal percepts from their ontological projections of mental appearance onto physical phenomena; thus, even when a chromatic change alters perceived hue and saturation, observers can reliably infer the cause, the constancy of the underlying surface spectral reflectance.

The ability to perceive the shapes of things as enduring through changes in how they stimulate our sense organs is vital to our sense of stability in the world. But what sort of capacity is shape constancy, and how is it reflected in perceptual experience? This paper defends a pluralist account of shape constancy: There are multiple kinds of shape constancy centered on geometrical properties at various levels of abstraction, and properties at these various levels feature in the content of (...) perceptual experience, governing patterns of apparent shape similarity. I propose that the varieties of shape constancy are subserved by the syntactic complexity of perceptual shape representations. By assigning discrete constituents to various abstract shape parameters, these representations attune us to the preservation of certain abstract shape properties through changes in more determinate shape properties. Finally, I draw broader lessons concerning the nature and function of perceptual constancy. (shrink)

Patients suffering from the Cotard syndrome can deny being alive, having guts, thinking or even existing. They can also complain that the world or time have ceased to exist. In this article, I argue that even though the leading neurocognitive accounts have difficulties meeting that task, we should, and we can, make sense of these bizarre delusions. To that effect, I draw on the close connection between the Cotard syndrome and a more common condition known as depersonalisation. Even though they (...) are not delusional, depersonalised patients seem to have experiences that are quite similar to those of Cotard patients. I argue that these experiences are essentially characterised by a lack of subjective character and of two other structural features of experience, which I call ‘the present character’ and ‘the actual character’. Cotard's nihilistic delusions simply consist in taking these anomalous experiences at face value. (shrink)

In recent discussions of two important issues in the philosophy of perception, viz. the problems of perceptual presence and perceptual constancy, Merleau-Ponty’s ideas have been garnering attention thanks to the work of Sean Kelly and Alva Noë. Although both Kelly’s normative approach and Noë’s enactive approach highlight important aspects of Merleau-Ponty’s view, I argue that neither does full justice to it because they overlook the central role that style plays in his solution to these problems. I show that a closer (...) look at the Phenomenology and several other texts from this period reveals that, on Merleau-Ponty’s account, we are able to perceive the absent features of objects as present, constant properties, and constant objects because we recognize that the objects we perceive have a unique style that persists through and unifies all their appearances.

This paper resolves a paradox concerning colour constancy. On the one hand, our intuitive, pre-theoretical concept holds that colour constancy involves invariance in the perceived colours of surfaces under changes in illumination. On the other, there is a robust scientific consensus that colour constancy can persist in cerebral achromatopsia, a profound impairment in the ability to perceive colours. The first stage of the solution advocates pluralism about our colour constancy capacities. The second details the close relationship between colour constancy and (...) contrast. The third argues that achromatopsics retain a basic type of colour constancy associated with invariants in contrast processing. The fourth suggests that one person-level, conscious upshot of such processing is the visual awareness of chromatic contrasts ‘at’ the edges of surfaces, implicating the ‘colour for form’ perceptual function. This primitive type of constancy sheds new light on our most basic perceptual capacities, which mark the lower borders of representational mind. (shrink)

The knowledge of truth, in Plato, is an experience that calls for conversion of the soul (μεταστροφή, περιστροφή). The basic feature of this experience consists in some sort of connection, which is constantly at work, between rational arguments and their non-rational conditions, briefly, lógos and páthos. How does this connection show up in Plato? Its crucial importance emerges many times at both narrative (récit) and theoretical level. In the three parts of my contribution, I show how logos-pathos intertwines with Plato's (...) notion of conversion considered as a double-sided phenomenon, as both "process" of moral education and "noetic event".

In this paper, I offer a new solution to the old problem of how best to understand the meaning of the word ‘logos’ in the extant writings of Heraclitus, especially in fragments DK B1, B2 and B50. On the view I defend, Heraclitus was neither using the word in a perfectly ordinary way in these fragments, as some have maintained, nor denoting by it some kind of general principle or law governing change in the cosmos, as many have claimed. Rather, (...) I argue, Heraclitus deliberately traded on the ordinary use of the word in his time (to refer to a written or spoken presentation of things as ‘thus and so’) to denote the world’s constant presentation of itself as ‘thus and so’ to all of us in our experience – a kind of cosmic self-revelation. I show how this captures the sense in which ‘the logos’ is said to be ‘common’ (xunos) and to be the kind of thing most people fail to comprehend even before hearing Heraclitus’ own account, all without detaching Heraclitus’ use of the word from its ordinary contemporary meaning. This interpretation suggests Heraclitus was a thinker more centrally concerned with human (mis)understanding than with speculative cosmology. (shrink)

For a stable visual world, the colours of objects should appear the same under different lights. This property of colour constancy has been assumed to be fundamental to vision, and many experimental attempts have been made to quantify it. I contend here, however, that the usual methods of measurement are either too coarse or concentrate not on colour constancy itself, but on other, complementary aspects of scene perception. Whether colour constancy exists other than in nominal terms remains unclear.

In this journal, Schulte develops a novel solution to the problem of distal content: by virtue of what is a mental representation about a distal object rather than a more proximal cause of that representation? Schulte maintains that in order for a representation to have a distal content, it must be produced by a constancy mechanism, along with two other conditions. I raise three objections to his solution. First, a core component of Schulte's solution is just a restrictive version of (...) Dretske's solution, but Schulte gives no argument for his restriction. Second, his proposed solution to a disjunction problem is ad hoc. Finally, his ‘far-out’ version of the distality problem is not a version of the distality problem at all. I conclude that Dretske's solution is preferable to Schulte's. (shrink)

Can young children such as 3-year-olds represent the world objectively? Some prominent developmental psychologists—such as Perner and Tomasello—assume so. I argue that this view is susceptible to a prima facie powerful objection: To represent objectively, one must be able to represent not only features of the entities represented but also features of objectification itself, which 3-year-olds cannot do yet. Drawing on Burge's work on perceptual constancy, I provide a response to this objection and motivate a distinction between three different kinds (...) of objectivity. This distinction helps advance current research on both objectivity and teleological action explanations in young children. (shrink)

Some experiments in perceptual psychology measure perceivers’ phenomenal experiences of objects versus their cognitive assessments of object properties. Analyzing such experiments, this article responds to Pizlo’s claim that much work on shape constancy before 1985 confused problems of shape ambiguity with problems of shape constancy. Pizlo fails to grasp the logic of experimental designs directed toward phenomenal aspects of shape constancy. In the domain of size perception, Granrud’s studies of size constancy in children and adults distinguish phenomenal from cognitive factors.

At Sophist 260e3-261a2, the Eleatic Stranger claims that in order to demonstrate that falsehood is, he and Theaetetus must first track down what speech (logos), opinion (doxa), and appearance (phantasia) are, and then observe the communion (koinōnia) that speech, opinion, and appearance have with non-being. The Stranger, however, never explicitly discusses the communion of speech, opinion, and appearance with non-being. Yet presumably their communion is implicit in his account of falsehood, given his claim that observing that communion is needed in (...) order to demonstrate that falsehood is (260e5-a2). This essay seeks to make the communion that speech has with non-being explicit. I argue that speech has communion with non-being in that the things and actions speech combines together by means of nouns and verbs need not be combined in a way that reveals how the being a given speech is about combines ontologically with other beings.

This chapter considers the ways in which whiteness as a skin color and ideology becomes a dominant level that sets the background against which all things, people and relations appear. Drawing on Merleau-Ponty's phenomenology, it takes up a series of films by Bruce Nauman and Marlon Riggs to consider ways in which this level is phenomenally challenged providing insights into the embodiment of racialization.

Purpose. The author believes that the main topic of philosophical studies of Heraclitus was not nature, not dialectics, and not political philosophy; he was engaged in the development of philosophical anthropology, and all other questions raised by him were subordinated to it to one degree or another. It is anthropology that is the most "dark" part of the teachings of this philosopher, therefore the purpose of this article is to identify the hidden anthropological message of Heraclitus. In case of success, (...) it will become clear what made him "darken". Theoretical basis. The methodological basis of the article is the anthropological understanding of fragments of Heraclitus’ texts presented in a historical and philosophical context. Originality. The philosophical concept of Heraclitus is still a mystery for researchers of his work. The author of the article proposed such a variant of interpretation, within the framework of which different elements of this concept fit into a consistent model. Conclusions. The article proves that although the anthropological turn in philosophy is traditionally associated with the activities of the sophists and Socrates, the previous philosophical thought was also not devoid of anthropological ideas. Moreover, pre-Socratic philosophers posed problems, the interpretation of which brought the doctrine of man to the level of high-order abstractions, while surprisingly preserving the concreteness of the life-meaning questions that confront him. And one of the brightest representatives of pre-Socratic anthropology was Heraclitus of Ephesus. Religion was the motivator that made him study the world, man, and society. The doctrine of the Logos developed by Heraclitus had a tremendous impact on Plato and Philo of Alexandria, and through them on the author of the Fourth Gospel, who begins his story with a "Greek" rethinking of the mystery of the Incarnation. If Heraclitus claimed that a person carries a particle of the Logos, then John proclaimed that the Logos itself incorporated a particle of man. Despite all the differences between these approaches, each of them postulated the cosmic significance of human existence, which means that it brought anthropology to the ontological level. (shrink)

A close reading of Socrates' refutation of the final proposed definition of knowledge, "true opinion with an account." I examine the provocations to further thinking Socrates poses with his dilemma of simplicity and complexity and then by his rejections of the three senses of "account," and I argue that these provocations guide the responsive reader to that rich and determinate understanding of the sort of 'object' which knowledge requires that the Parmenides and the Eleatic dialogues will go on to explicate.

In this article, I elucidate the significance of Heidegger’s ‘question of being’ from a topological point of view by explaining the relationship between his thought of place and language. After exploring various hermeneutic strategies of reading Heidegger’s oeuvre, I turn to Richard Capobianco’s interpretation of Heidegger and critically engage with his idea of the experience of being itself as the ‘luminous selfshowing of logos’. In doing so, I explain the later turn from ‘truth’ to ‘place’ and articulate why logos needs (...) to be conceived as the gathering site of the presencing of being. In arguing against the primacy of passive receptivity and active projection, I put forward the primacy of language as the topos and logos of being. In returning to the Capobianco-Sheehan debate, I conclude by explaining why Heidegger’s placerelated notions cannot be thought metaphorically. (shrink)

This paper presents and critically discusses the “logos approach to quantum mechanics” from the point of view of the current debates concerning the relation between metaphysics and science. Due to its alleged direct connection with quantum formalism, the logos approach presents itself as a better alternative for understanding quantum mechanics than other available views. However, we present metaphysical and methodological difficulties that seem to clearly point to a different conclusion: the logos approach is on an epistemic equal footing among alternative (...) realist approaches to quantum mechanics.

A close reading of Socrates’ arguments against the proposed definition of knowledge as true opinion together with a logos (“account”). I examine the orienting implications of his apparently destructive dilemma defeating the so-called dream theory and of his apparently decisive arguments rejecting the notions of “account” as verbalization, as working through the parts of the whole of the definiendum, and as identifying what differentiates the definiendum from all else. Whereas the dilemma implies of the object of knowledge that it must (...) be both simple and complex, the last two notions of “account” point to the kinds of discursive analysis that can do justice to its complexity; together the refutations suggest the relation between noesis, that is, eidetic intuition of the object in its simplicity, and discursive analysis of the object in its complexity that knowledge requires.

A quarter of a century ago, the first systematic behavioral experiments were performed to clarify the nature of color constancy—the effect whereby the perceived color of a surface remains constant despite changes in the spectrum of the illumination. At about the same time, new models of color constancy appeared, along with physiological data on cortical mechanisms and photographic colorimetric measurements of natural scenes. Since then, as this review shows, there have been many advances. The theoretical requirements for constancy have been (...) better delineated and the range of experimental techniques has been greatly expanded; novel invariant properties of images and a variety of neural mechanisms have been identified; and increasing recognition has been given to the relevance of natural surfaces and scenes as laboratory stimuli. Even so, there remain many theoretical and experimental challenges, not least to develop an account of color constancy that goes beyond deterministic and relatively simple laboratory stimuli and instead deals with the intrinsically variable nature of surfaces and illuminations present in the natural world.

The paper aims at reconstructing the fundamentals of the sophistic anthropology. Contrary to the recognized view of the humanistic shift which took place in the sophistic thought, there is evidence that the sophists were continuously concerned with the problems of philosophy of nature. The difference between the sophists and their Presocratic predecessors was that their criticism of the philosophical tradition and the transformative answers given to the old questions were the basis and the starting point of the " ethical " (...) and " rhetorical " part of their intellectual activity. This natu-ralistic perspective is reflected in their research in the field of medicine and biology, in the discussion about " the human nature " , and in their interest in the individual physiological and mental conditions, which determine the state of the human body and the behaviour of a man. The sophists pioneered in linguistic, rhetorical, and philological studies. To enhance the power of persuasion, they investigated how various mental conditions influenced cognitive processes and physiological reactions. Thus they started a thorough examination of the human psyche, initiating the field of psychology. (shrink)

The logos question, one of the most important among the subjects that traverse the Plato's Sophist, has in fact some different aspects: the criticism of father Parmenides' logos, that is unable to speak about the not-being, but also about the being; the relations between logos and its cognates, phantasia, doxa and dianoia; the logos’ complex structure, that is a compound with onoma and rema; the difference between naming and saying, two distinct but inseparable actions; the logical and ontological conditions that (...) make possible to say the truth, or to lie or simply to joke; the necessity of a most flexible logos that allows us to speak about the not-being, and about the being, but at the same time is a logos dangerously similar to the sophist’ one; finally, the identity between the power to produce “spoken images” and the very power to speak. The aim of the present article is giving a systematical view of the matter that grasps all these faces. (shrink)

While it is widely regarded that intellectual humility is among the intellectual virtues, there is as of yet little consensus on the matter of what possessing and exercising intellectual humility consists in, and how it should be best understood as advancing our epistemic goals. For example, does intellectual humility involve an underestimation of one’s intellectual abilities, or rather, does it require an accurate conception? Is intellectual humility a fundamentally interpersonal/social virtue, or might it be valuable to exercise in isolation? To (...) what extent does intellectual humility demand of us an appreciation of how the success of our inquiries depends on features of our social and physical environment beyond our control? These are just a few of the many questions that are crucial to getting a grip on this intellectual virtue and why we might aspire to cultivate it. Furthermore, and apart from the nature and value of humility, it is worthwhile to consider how this notion, properly understood, might have import for other philosophical debates, including those about (for example) scepticism, assertion, epistemic individualism and anti-individualism, and the philosophy of education. This special issue brings together a range of different philosophical perspectives on these and related questions to do with intellectual humility with an aim to contributing to this important and timely topic.

El decir es anterior y va más allá del hablar, se vale del hablar y constituye la determinación del hablar. No hay un hablar sin un decir y sí puede haber un decir sin un hablar. El acto lingüístico es la manifestación del lenguaje, la lengua, el pensamiento y el conocimiento. Es fruto de un hablar, está determinado por un decir, presupone un conocer y revela la actitud del hablante, un sujeto libre e histórico, que es, a la vez, sujeto (...) hablante, dicente y cognoscente, ante la realidad y el mundo. De la misma manera que no se da un hablar sin un decir, tampoco se da un decir sin un conocer. En su génesis más profunda el conocer determina al decir y éste al hablar. Así, pues, el «ser hablante» (Coseriu) es, a la vez, el sujeto «dicente» (Ortega y Gasset) y el sujeto cognoscente (Coseriu, Ortega y Gasset, Heidegger, Aristóteles), porque se realiza a sí mismo en el acto del hablar y éste está determinado por el acto del decir y en última instancia por el acto del conocer. El decir define al hablante ante la realidad y el mundo y da soporte a lo que es la realidad y el mundo, que no es más que aquello a lo que el sujeto hablante, dicente y cognoscente le atribuye el ser o realidad. El ser humano, «coexistencia actuante de mí o yo con la circunstancia o mundo» (Ortega y Gasset), se libera de la necesidad vital en la que está inmerso, de la circunstancia a la que está inexorablemente ligado, mediante el conocer. Por el conocer el ser humano atribuye a eso que le rodea y afecta «el ser», haciendo de ello «cosas» y «mundo» constituido por «cosas». Todo esto se manifiesta en el acto lingüístico, que es un acto creador en un triple sentido: crea las cosas y el mundo (contenidos de conciencia, significados), crea la realidad de las cosas y el mundo, y crea la expresión de lo que es las cosas y el mundo (el lenguaje y la lengua) mediante lo dicho (lektón) determinado esto por el pensamiento (lógos). El acto lingüístico es creación (poiesis) y es manifestación (apóphansis), acto de crear un mundo y acto de desvelar el mundo interior del sujeto hablante, dicente y cognoscente, acto de desvelar lo que está oculto y que ahora es no-oculto o verdadero (a-lethés). El hablar, el decir y el conocer son acciones vitales del ser humano. El hablar es una acción vital del sujeto creador que le viene de fuera, de la comunidad; el decir es la acción vital que le viene de dentro y que proyecta él mismo hacia fuera, hacia la comunidad; y el conocer es el acto mismo de creación de un sujeto, que es, opuestamente, libre e histórico, absoluto y limitado, creador de formas y participante de formas comunes creadas en la comunidad. El hablar en sí mismo, al igual que la lengua, es a-circunstancial y tiene que ver con la creación en términos absolutos e históricos. El decir como manifestación del interior del sujeto hablante, dicente y cognoscente tiene que ver con la verdad o aquello que se manifiesta desvelándose (a-létheia). De esta manera, podemos ver dos clases de pensamiento o logos: el logos a-circunstancial o intersubjetivo o histórico, lógos semantikós, y el logos que manifiesta una realidad interior y crea una realidad exterior desde el interior del sujeto creador o lógos apophantikós. La lingüística del decir que ahora se presenta recoge una propuesta en el mismo sentido hecha por Ortega y Gasset y es la continuación de la lingüística del hablar de Coseriu. Hace un replanteamiento de la realidad radical, el ser hablante de Coseriu, que es concebido ahora como el sujeto hablante, dicente y cognoscente. Estudia el acto lingüístico, acto del hablar, decir y conocer, como la manifestación primera de la intención significativa de cada sujeto. Se basa en los principios de la lingüística del hablar de Coseriu, especialmente en los que describen el plano universal e individual del hablar, es decir, los principios de la confianza en el hablar del otro y de la congruencia y coherencia en el hablar. Mira, por consiguiente, al acto lingüístico como «producción», como aquello que se crea en el acto único del hablar, decir y conocer. La finalidad de la lingüística del decir es llegar la génesis misma del lenguaje, que no es más que la génesis del acto lingüístico. Analiza el acto lingüístico como la manifestación del acto del conocer, el cual partiendo de la aísthesis o intuición sensible (Ortega y Gasset, Heidegger, Aristóteles) o intuición inédita del hablante (Coseriu), se descompone en una serie de operaciones intelectivas, cada una de las cuales contribuye a configurar de una manera dada la «aprehensión del ser» inicial e inédita. Estas operaciones intelectivas son: la selección, el establecimiento de una designación, la creación de una clase o esencia, la relación, la nominación y la determinación. Tras la presentación y justificación de lo que es cada uno de los conceptos indicados arriba (los cuatro primeros capítulos), el libro dedica un capítulo a cada una de estas operaciones intelectivas, analizada e ilustrada con ejemplos.

In this essay, our goal is to discover science in Martin Heidegger's Introduction to Metaphysics, lecture notes for his 1935 summer semester course, because, after all, his subject is metaphysica generalis, or ontology, and this could be construed as a theory of the human brain. Here, by means of verbatim quotes from his text, we attempt to show that indeed these lectures can be viewed as suggestion for an objective scientific theory of human perception, the human capacity for deciphering phenomena, (...) ie. hermeneutics in its broadest sense. His added notes from the 1953 edition, all of which are comments, not corrections, imply that he never abandoned these thoughts on metaphysics, despite all of his utterances about a need to overcome it, and their popular interpretations to that effect. In his presentation, he further develops the colorful and intuitive style, an hermeneutic language, that he had created in his earlier work Being and Time. Of human existence he speaks in such expressions as being-there -- ``Dasein" -- and being-in-the-world, the latter term no longer explicit in the 1935 lectures. The lectures can be read as a pre-scientific analysis of how man, being-there, perceives his environment, artfully managing to deal with the manifold challenges posed by the phenomenal structures of the universe. Man attentively recognizes and deciphers their pre-linguistic contents and, while trying to make sense of it all, puts into words his awareness. There are numerous passages in Heidegger's work where he in fairly concrete terms provides us with hints for a perceptive science that, as it turns out and is demonstrated below in this essay, can be explained in terms of recent advances in neuroscience. It would be implausible, even unthinkable, unimaginable, for there not to be found essential agreement between on one hand his philosophical insights gained by hermeneutics of Dasein, into how our brain functions to let us know what's happening & on the other hand, scientific discoveries obtained through anatomy, EEG, fMRI, TMS, electrode implants, etc, of brain structures & functions employed in perception of the momentary scene. A nexus between science and philosophy is provided in Heidegger's definitive treatment of the Logos, here interpreted as a structural version of Platonic forms (Burchard, 2014). This allows for neurolinguistic brain functions to serve as meta-context for Heidegger's being-in-the-world. The logical functions of Dasein's anatomical brain are performed by the logos machine, formerly the human soul, using top-down processing based on a global context, the noumenal cosmos which humans maintain internally. Heidegger's 1942/43 winter semester lectures Parmenides extend in unbroken fashion his 1935 work, proving that he never abandoned, as is widely claimed, his metaphysical avenue of thought. (shrink)

In this paper I argue that we can solve the interpretation problem of quantum mechanics and the question of ontology of Quantum Field Theory on the basis of simple metaphysical position: The connection of the phase space with the ancient Theory of Logi of Beings, which is, by giving ontological meaning to the entities which "live" at the phase space, the Hamiltonian or Lagrangian formalism. There is a physical subject of such functions and it is the logos of a being. (...) Therefore we can refer to the logical space as the total sum of logi of being. The result of this position is that we can attribute to the wave function a physical meaning, a special case of logos of a being and also give an ontological meaning at a quantum field. The developed metaphysical scheme can interpret the quantum paradoxes, by using the commonly accepted mathematical formalism. It can also interpret certain issues of Quantum Field Theory, although further study of this topic is necessary. (shrink)

In this paper, our intention is to present the main aspects of the understanding of the logos in Philo of Alexandria. Philo’s reception of this notion is especially important because his insights significantly influenced the development of patristic philosophy, and these influences, through the mediation of scholasticism, reached the modern age. Philo has a very important role in creating the Judeo-Christian heritage, and represents an important link for understanding the formation of the basic matrices of this worldview. For the first (...) time, a thorough synthesis of Semitic and Hellenic heritage was performed with him. The use of the term logos in that synthesis proves to be one of the key ones, since it is precisely this term, which has never lost its philosophical significance, partly and thanks to Philo, that is identified with the Son of God of the Christian tradition.

The article explores critical elements to understand how Origen elaborates his mystical theology in his Commentary on John. The spiritual progress process implies that rational beings are guided, by God’s Logos, from the practical life to the theoretical one becoming son or daughter of God, in the likeness of the Logos. This process aims at knowing the Father as he is known by the Logos. The article has two parts: 1. The Father’s presence, through the Logos, in rational beings, and (...) 2. a brief characterisation of the salvation, particularly in the perspective of the mediation by the Son of God. (shrink)

It has long been theorized that Heidegger’s idea for Dasein was highly influenced by the Chinese notion of the Dao. This is due to a misinterpretation on behalf of Heideggerian scholars and others of what the Dao represents. In fact, Heidegger, in explicating what he thought to be “the most extreme inversion of φύσης-ουσία [phusis-ousia],” made this equal to “Chinese-like ‘constancy,’” which is the basis of the Dao. Taking what Heidegger interpreted phusis to be (derived from Aristotelian metaphysics and an (...) assumption of pre-Socratic thought) as a process of unconcealment from continuing re-concealment which signals a kind of “truth” of being [phusis], that which calls for constant presence is inauthentic Dasein, rather than authentic Dasein. In other words, Heidegger’s idea of what inauthentic Dasein calls for could be explained within Aristotle’s system as equal to aiming to replace phusis with the know-how of τέχνη [techne]. The Dao, as rightfully understood and utilized by the master craftsman and the Sage, is accessible, constant, and knowable. This could not be in more opposition to Heidegger’s notion of phusis.

The arguments I examine in this chapter are not necessarily from Anaximander. Anaximander is generally known for having put the ἄπειρον as a principle (ἀρχή), probably due to the greater radicality with which he affirmed the physical – perhaps also epistemic – indeterminacy (and the consequent ineffability) of the principle of the φύσις. However, it is well known that, according to Aristotle, a large part of archaic physics or physiology had placed the ἄπειρον as the origin and foundation of the (...) becoming, to the point of deifying it as a living, surrounding, ruling and probably animated body (σῶμα), whose nature was separate or at any rate different from visible reality and its major components. I will call it Arkhé Apeiros Theory (TAA). A TAA then exists for archaic philosophy in general, and not only for Anaximander, and is based on a fairly clear common feature, namely the idea that the principle of nature is an indeterminate body (σῶμα ἄπειρον) and is, therefore, although to a variable extent, unknowable-ineffable.

Personal indexicals are often taken to refer to the agent of an expression’s context, but deviant uses (e.g. ‘I’m parked out back’) complicate matters. I argue that personal indexicals refer to the extended self of the agent, where the extended self is a mereological chimera incorporating whatever determines our behavioral capacities. To ascertain the persistence conditions of personal identity, I propose a method for selecting a level of description and a set of functional properties at that level that remain constant (...) over a lifetime. I argue for functional constancy, and against continuity, as the central determinant of diachronic identity. (shrink)

Taking Thomas Aquinas's interpretation of the prologue of St John's gospel (in his Lectura super loannem Evangelium) as example, I first discuss eight differences between medieval biblical interpretation and modern exegesis, especially Aquinas's frequent use of philosophical opinions in interpreting the Bible, taken mostly from Aristotle. Second, I account for these differences by reconstructing Aquinas's hermeneutics, hinging, as is shown, upon the assumption that scripture was authored by God infallible and, therefore, only contains true statements. From this starting point Aquinas (...) is lead to a holistic hermeneutics: The interpretation of a biblical statement can be judged on only within the context of an entire theory of God, the world, and of the interpretation of the other biblical statements. Thirdly, this view is discussed systematically and critically. (shrink)

The relationship between knowledge and vision seems really consolidated. It started in ancient Greece and we can found its basis in Plato. The history of logos as reason and as western foundation of culture gives us enormous examples in terms of metaphors and approaches in the knowledge-vision relationship. «I see it» is like «I know it». However if we look at the basis of logos we find the deep meaning of gathering, composition, bond and bind (lèghein), so as to we (...) could choose «to gather» as the best translation of logos (Hoffmann). My aim is to show how this key feature is represented by sounds. To think is to link information, memories and so on and the principal property of sound is union and merger. We can argue for a «sonorous thought» but in reality this property is simply the founding element of thought and reason. In fact if we analyse the limits of our knowledge (Kant, Plessner) we discover the incorrectness of knowledge-vision relationship – like the knowledge-discourse relationship. We should investigate this guideline as the recent research for Covid-19 vaccine has shown. (shrink)
