I argue that a study of the Nicomachean Ethics and of the Parva Naturalia shows that Aristotle had a notion of attention. This notion captures the common aspects of apparently different phenomena like perceiving something vividly, being distracted by a loud sound or by a musical piece, focusing on a geometrical problem. For Aristotle, these phenomena involve a specific selectivity that is the outcome of the competition between different cognitive stimuli. This selectivity is attention. I argue that Aristotle studied the (...) common aspects of the physiological processes at the basis of attention and its connection with pleasure. His notion can explain perceptual attention and intellectual attention as voluntary or involuntary phenomena. In addition, it sheds light on how attention and enjoyment can enhance our cognitive activities. (shrink)

No processo do conhecimento a imaginação desempenha para Hegel o estágio no qual a mente humana dissocia o objeto em dois diferentes conteúdos, o conteúdo-coisa do mundo externo e o conteúdo interno da própria mente, de tal modo que ambas as versões do mesmo devem corroborar-se mutuamemente ao modo de uma síntese simples de elementos heterogéneos que apenas em seu cotejamento reconhecem sua identidade. Na atividade de compreensão, ao contrário, este dualismo é suprassumido e, com ele, o empirismo e a (...) teoria correspondista da verdade que, aos olhos de Hegel, está em sua base. (shrink)

In the tripartite psychology of the Republic, Plato characterizes the “spirited” part of the soul as the “ally of reason”: like the auxiliaries of the just city, whose distinctive job is to support the policies and judgments passed down by the rulers, spirit’s distinctive “job” in the soul is to support and defend the practical decisions and commands of the reasoning part. This is to include not only defense against external enemies who might interfere with those commands, but also, and (...) most importantly, defense against unruly appetites within the individual’s own soul.1 Spirit, according to this picture, is by nature reason’s faithful auxiliary in the soul, while appetite is always a potential enemy to be watched ..

In De Anima III.3 Aristotle presents his official discussion of phantasia (“imagination” in most translations). At the very outset of the discussion Aristotle offers as an endoxon that “phantasia is that in virtue of which we say that a phantasma occurs to us” (428a1-2). Now a natural reading of this claim, taken up by many commentators, can pose a problem for Aristotle’s overall account of perception. Here I argue that, although it would be silly to deny that Aristotle considers phantasia (...) to be that in virtue of which a phantasma occurs to someone, it is not silly to deny that phantasmata are present in every case in which phantasia is operative. This suggestion bolsters the idea that, according to Aristotle’s account of veridical perception, we can understand the world as making itself perceptually manifest to the perceiver. (shrink)

Pyrrhonian sceptics claim, notoriously, to assent to the appearances without making claims about how things are. To see whether this is coherent we need to consider the philosophical history of ‘appearance’(phainesthai)-talk, and the closely related concept of an impression (phantasia). This history suggests that the sceptics resemble Plato in lacking the ‘non-epistemic’ or ‘non-doxastic’ conception of appearance developed by Aristotle and the Stoics. What is distinctive about the Pyrrhonian sceptic is simply that the degree of doxastic commitment involved in his (...) assent to an impression is asymptotally low. (shrink)

Aphantasia, i.e., the inability to voluntarily form visual mental images, affects approximately 2 to 5 percent of the population and plays an important role in a more general debate revolving around the role of imagery for our cognition. This thesis investigates aphantasia by means of an interdisciplinary approach, combining insights from contemporary neuroscientific research with historical philosophical arguments, with a specific focus on the later philosophy of Ludwig Wittgenstein. A new theoretical concept, meta-imagination, is developed and it is argued that (...) the concept can explain why aphantasics perform successfully on a wide range of visual imagery tasks, thus providing important implications for the more general debate about the connection between imagery and cognition.

Through the reconstruction of Leibniz's theory of the degrees of knowledge, this e-book investigates and explores the intrinsic relationship of imagination with space and time. The inquiry into this relationship defines the logic of imagination that characterizes both human and non-human animals, albeit differently, making them two different species of imaginative animals. -/- Lucia Oliveri explains how the emergence of language in human animals goes hand in hand with the emergence of thought and a different form of rationality constituted by (...) logical inferences based on identity and contradiction, principles that are out of reach of the imagination. The e-book concludes that the presence of innate principles in human animals transforms the way in which they sense-perceive the world, thereby constantly increasing the distinction between human and non-human animals. -/- Keywords: human and non-human animals, Leibniz and Locke on ideas, Leibniz on bodies, Leibniz on conceivability, Leibniz on degrees of knowledge, Leibniz on degrees of perception, Leibniz on innate ideas, Leibniz on modality, Leibniz on similarity and congruence, Leibniz on space and time, Leibniz’s philosophy of language, theory of types.

Aristotle’s works on natural science show that he was aware of the affective powers of colour. At De an. 421a13, for example, he writes that hard-eyed animals can only discriminate between frightening and non-frightening colours. In the Nicomachean Ethics, furthermore, colours are the source of pleasures and delight. These pleasures, unlike the pleasures of touch and taste, neither corrupt us nor make us wiser. Aristotle’s views on the affective powers of colours raise a question about the limits he seems to (...) place on the affective powers of pictures at De an. 427b15-24, where he implies that pictures do not affect us immediately. In this paper, I examine the contrast between the affective powers of colour and the affective powers of pictures. I argue that colours can give rise to pleasure and pain in themselves and generate emotions incidentally. Similarly, pictures can please us or affect us in themselves and incidentally. In light of this account, I suggest that, on a plausible reading of De an. 427b15-24, the affective powers of pictures as mimetic objects are not immediate because they require an intervening cause in order to be effective. The representations of pictures and statues affect us either with the mediation of deception or with the mediation of interpretation. (shrink)

Al comparar la visión de Avicena y Kant sobre la imaginación, encontramos una sorprendente congruencia en sus doctrinas. Las doctrinas de Kant sobre la síntesis de la imaginación en su Deducción Trascendental tiene notables similitudes con la visión de Avicena. Tanto para Avicena como para Kant, la imaginación sirve para conectar lo fenoménico con lo nouménico. Al menos esta comparación tiene el doble uso de colocar las doctrinas de Kant en el contexto de la tradición aristotélica y de iluminar la (...) importancia moderna que tiene el pensamiento de Avicena. Dado que el pensamiento de Kant nos es más familiar que el de Avicena, podemos usar a Kant también para ayudar a comprender las tesis de Avicena. Por otro lado, esta comparación puede ayudar a sostener la tesis de que la comprensión de Kant yace en gran medida en sus raíces medievales y post-medievales —tal como ocurre con Copérnico, que, en su propia “Revolución Copernicana”, seguía ciertas tradiciones anteriores.

A theory of the structure and cognitive function of the human imagination that attempts to do justice to traditional intuitions about its psychological centrality is developed, largely through a detailed critique of the theory propounded by Colin McGinn. Like McGinn, I eschew the highly deflationary views of imagination, common amongst analytical philosophers, that treat it either as a conceptually incoherent notion, or as psychologically trivial. However, McGinn fails to develop his alternative account satisfactorily because (following Reid, Wittgenstein and Sartre) he (...) draws an excessively sharp, qualitative distinction between imagination and perception, and because of his flawed, empirically ungrounded conception of hallucination. His arguments in defense of these views are rebutted in detail, and the traditional, passive, Cartesian view of visual perception, upon which several of them implicitly rely, is criticized in the light of findings from recent cognitive science and neuroscience. It is also argued that the apparent intuitiveness of the passive view of visual perception is a result of mere historical contingency. An understanding of perception (informed by modern visual science) as an inherently active process enables us to unify our accounts of perception, mental imagery, dreaming, hallucination, creativity, and other aspects of imagination within a single coherent theoretical framework.

Kant's critical philosophy promises to overturn both Empiricism and Rationalism by arguing for the necessity of a passive faculty, sensibility, and an active faculty, understanding, in order for cognition to obtain. Kant argues in favor of sense impression found in standard empirical philosophies while advocating conceptual necessities like those found in rational philosophies. It is only in the synthesis of these two elements that cognition and knowledge claims are possible. However, by affirming such a dualism, Kant has created yet another (...) problem familiar to the history of philosophy, one of faculty interaction. By affirming two separate and exclusive capacities necessary for cognition, Kant has bridged the gap between the two philosophical traditions, but created a gap that must be overcome in order to affirm his positive programmatic. Kant himself realizes the difficulty his new philosophy faces when he claims the two sources of knowledge must have a "common, but unknown root." To complete Kant's program one must ask: "What bridges the gap between sensible intuition and conceptual understanding?" In my dissertation, I turn to Kant's philosophy and find the answer to this question in the productive imagination. In order to evaluate the viability of this answer, I problematize the imagination as it has been found in the history of Western philosophy. By tracing the historical use of the imagination in archetypal figures from both empiricist and rationalist traditions, one finds a development of imagination that culminates in the fundamental formulation found in Kant's Critique of Pure Reason. In his critical philosophy, Kant synthesizes the imagination and the use of imagination found in both traditions, thus demonstrating its role in both sensation and understanding. By employing the imagination at both sensorial and conceptual levels, Kant has found, I argue, the liaison that overcomes the dualism established by his requirements for knowledge, as well as the common root for both.

In an attempt to reject Cartesian Dualism, some philosophers and scientists of the late twentieth century proposed a return to the ancient position that Descartes had opposed, i.e., Aristotle’s psychological hylomorphism, which applied to living beings the ontological thesis, according to which every substance is a compound of matter (hyle) and form (morphe). In this perspective, the soul is actual possession of the body’s capacity to perform a series of life functions. Therefore, according to Aristotle, soul and body are reciprocally (...) interdependent aspects of the living being, so that we must consider the former as an enmattered form, and the latter as an enformed or ensouled matter. This means that, for Aristotle, all the functions of the soul, even the highest ones like thought, are essentially connected with the body, since they ultimately require sensations. This paper illustrates and supports this doctrine in detail, especially in relation to the cognitive processes of the human mind. (shrink)

This project is guided and motivated by the question concerning the nature of the phantasm as that which mediates between sensation and intellection in John Duns Scotus' account of cognition. Scotus embraces Aristotle's claim that the intellect cannot think without the phantasm. The phantasm is in a corporeal organ, yet the immaterial intellect must act with it to produce an intelligible species. In this project I examine the critical elements of Scotus' cognitive theory in order to understand the nature of (...) the phantasm. In the first chapter I discuss key elements of Aristotle's metaphysics and give a close, textual reading of De Anima guided by his claim that the relationship of the body and soul is highly specific. I then focus on his claim in De Anima 2.12 that sensation involves the reception of the sensible form without the matter. In the second chapter, I discuss Scotus' key theological notions that guide and inform his cognitive project. The beatific vision requires the presence of the divine essence in its own existence to the intellect. As the highest cognitive experience, the beatific vision is definitive of all cognitive experience making the presence of the object to the cognitive faculty of central importance. The discussion of the incarnation shows that the world is sacralized and thus, is a worthy object of cognitive attention in itself. In the third chapter, I discuss Scotus' understanding of the body-soul relationship focusing on his notion of person to both secure the unity of the human being and to ground the mediation between sensation and intellection. In the fourth chapter, I first discuss Aquinas' claim that sensation requires a spiritual change. While Scotus's account is in many respects the same as Aquinas', Scotus does not maintain that sensation is primarily passive and is thus, able to account for cognitive attention by way of his understanding of the unity of the sense organ, immanent actions, and sensation as intuitive cognition. What emerges in this discussion is Scotus' particular understanding of an intentio by which the nature of the phantasm can be understood. (shrink)

In this paper we argue that Aristotle operates with a particular theoretical model in his explanation of animal locomotion, what we call the ‘centralized incoming and outgoing motions’ model. We show how the model accommodates more complex cases of animal motion and how it allows Aristotle to preserve the intuition that animals are self-movers, without jeopardizing his arguments for the eternity of motion and the necessary existence of one eternal unmoved mover in Physics VIII. The CIOM model helps to elucidate (...) Aristotle’s two central yet problematic claims, namely that the soul is the efficient cause of animal motion and that it is the internal supporting-point necessary for animal motion. Moreover, the CIOM model helps us to explain the difference between voluntary, involuntary and non-voluntary motions, and to square Aristotle’s cardiocentrism with his hylomorphism, but also, more generally, it provides an interesting way of thinking about the place of intentionality in the causal structure of the world.

An essential premise for discussing problems of modern cultural and religious importance is the proper understanding of memory and philosophical grounds for such concepts as memory and (...) recollection. Aristotelianism has been repeatedly mentioned as a main source of memory concepts, along with Plato, later Roman tradition and then mediaeval reconsiderations of Aristotelian texts. In my study I am following in parallel both Aristotle’s theory of memory and imagination and modern theories concerning Aristotelian epistemology and build arguments for the thesis that modern theories concerning the importance of induction in Aristotle’s epistemology miss an important link, namely, the key function of memory techniques for understanding the whole of Aristotle’s theory of knowledge. Memory is the domain of technique or art ( techne ) but not the grounding site for science. Truth and false are not an issue for Aristotle’s theory of knowledge because sensibility and theoretical intellect cannot be false. Memory, imagination and recollection as functions of an intermediary link are the most fluid and uncontrollable parts of the cognitive psyche, as they function as necessary bridges from corporeal sensitive knowledge to intellectual formal understanding. Memory is still corporeal as a function but delivers images for the intellectual activity. The whole process of knowledge depends on such a fluid and non rigorous function. Aristotle suggests natural memory can be pointed as the very cause for imperfection of knowledge. Human being is thus an insolvable epistemic duality since science needs memory but memory itself is rather the object of custom, art and technique. Science and religion have, according to such Aristotelian premise, a necessary common imaginary. (shrink)

El presente artículo examina el tránsito que, desde la percepción sensible hacia la imaginación, se hace en la psicología aristotélica, específicamente en el capítulo 3 del Libro III del De Anima y en el tratado Acerca de los ensueños. Tras un primer examen del uso que hace Aristóteles de los términos aisthesis y phantasía, y de examinar las razones por las cuales adscribe esta última a la facultad perceptiva del alma, se pone de presente la ampliación que del campo de (...) la percepción hace el Estagirita a partir de la consideración de fenómenos psicológicos como las pariciones perceptuales y postperceptuales, los engaños e ilusiones perceptivos y la llamada “percepción proposicional”. Para finalizar, se destaca la función mediador entre la percepción y el intelecto que cumple la phantasía y se distingue entre la imaginación sensitiva, una dedicada a la combinación de las imágenes y, finalmente, una imaginación de carácter racional y deliberativo.

The surviving writings of Epicurus and his followers contain several references to epibolê – a puzzling notion that does not receive discussion in the extant Epicurean texts. There is no consensus about what epibolê is, what it is of, and what it operates on and, moreover, its epistemological status is controversial. This article aims to address these issues in both Epicurus and later Epicurean authors. Part One focuses mainly on Epicurus’ Letter to Herodotus, highlights a crucial distinction hitherto unnoticed in (...) the literature between two different types of epibolê, and brings out he necessary connection between epibolê and the application of the criteria of truth. Part Two considers the philosophical merits of the traditional interpretation of epibolê as projection and/or attention. Part Three examines the two aforementioned types of epibolê in Lucretius and Philodemus and shows that these authors accord epibolê paramount epistemological and ethical importance. (shrink)

The commemorative forms of the Romans are marked by the ubiquity of two contrasting presentational modes: one essentially mimetic, rooted in the representational power of artistic forms, the other abstract and figurative, dependent on the presentation of cues for the summoning of absent yet necessary images. The mimetic mode was thoroughly conventional, and thus posed few problems of interpretation; the figurative knew no such orthodoxy and required a different and distinctive form of attention. At the tomb, epigraphic and sculptural forms, (...) each in its characteristic manner, addressed an audience habituated by tradition to respond to both of these modes, to grasp their differences, and to rise to the challenge implicit in the very fact of their contrast.

Whether Aristotle wrote the treatises of Metaphysics with different conceptions of the science of Being in mind has long puzzled scholars. The particular question that causes them unease is whether Aristotle’s enterprise in establishing the science of Being through the several treatises of Metaphysics is marked by a general science of Being, studying all departments of Being whatsoever, or whether his investigation of this science reflects an attitude towards a special metaphysics seeking knowledge of a special department of Being, in (...) this case, God, and therefore should be regarded as a science that is eminently theological. In this thesis, I aim to show that Aristotle’s enterprise in Metaphysics does not necessarily hinder reconciliation between the universal and the theological dimensions of the science of Being and that although Aristotle's conception of the science of Being is eminently theological it does not conflict with its also being universal. Furthermore, I aim to show that had the conception of the science of Being in Aristotle’s mind not been theological, it would not be universal either. (shrink)
