Proposes an innovative rethinking of Aristotle’s work as a system that integrates his theology with his doctrine of reproduction and life. In this deep rethinking of Aristotle’s work, Abraham P. Bos argues that scholarship on Aristotle’s philosophy has erred since antiquity in denying the connection between his theology and his doctrine of reproduction and life in the earthly sphere. Beginning with an analysis of God’s role in the Aristotelian system, Bos explores how this relates to other elements of his philosophy, (...) especially to his theory of reproduction. The argument he develops is that in talking about the cosmos, Aristotle rejected Plato’s metaphor of artisanal production by a divine Demiurge in favor of a biotic metaphor based on the transmission of life in reproduction, in which pneuma—not breath as it is often interpreted but the life-bearing spirit in animals and plants—plays a key and sustaining role as the vital principle in all that lives. In making this case, he defends the authenticity of the treatises De Mundo and De Spiritu as Aristotle’s, and demonstrates Aristotle’s works as a unified system that sharply and comprehensively refutes Plato’s, and in particular replaces Plato’s doctrine of the soul with a theory in which the soul is clearly distinguished from the intellect. “Bos offers a fresh, interesting, and important perspective. His interpretation will be very controversial, but if he is right, the standard Anglo-American interpretation of Aristotle will have to change radically.” — Malcolm Wilson, author of Structure and Method in Aristotle’s Meteorologica: A More Disorderly Nature.

Alexander of Aphrodisias picks up Aristotle’s insufficient treatment of simultaneous perception and develops an adequate solution for the problem, thereby offering an account of the unity of perceptual consciousness—the single mental activity of a single subject with complex content. I show the adequacy of the solution by using as criteria the requirements that have been identified by Aristotle and approved (and explained) by Alexander. I analyze Alexander’s solution in two turns. First, with respect to heterogeneous perceptibles, Alexander adopts and reformulates (...) Aristotle’s metaphorical account invoking the analogy with a point. Second, with respect to homogeneous opposites, accordingly, perception is judgement, but it involves physical changes in diverse parts of the primary sense-organ. By this account Alexander resolves the issue of the unity of the subject on the level of the capacity of the soul, and coordinates the complexity of content with the complexity on the physical level. In addition to being adequate, the solution is faithful to Aristotle. I suggest that the interpretative decisions Alexander makes (the clarification of the analogy; the reference he finds to the analogy; the two components of the solution, judgement and parts of the organ) form an ingenious extension of Aristotle’s treatment. Interestingly, even though many elements in Alexander’s interpretation are taken up by modern commentators, no one has followed it in its entirety, nor even treated it in its own right. (shrink)

Se realiza un estudio comparativo del problema de la percepción en Aristóteles y Maurice Merleau-Ponty, considerando el marco antropológico en el que se inscriben sus propuestas. Se establecen sus posibles puntos de contacto y sus diferencias más importantes. Se presta especial atención al vínculo entre el acto senso-perceptual yel movimiento, así como al problema de la conciencia perceptual y a la cuestión de la actualidad común entre el sentiente y el sensible.

This is a book about the metaphysics of perception and discusses touch, audition, and vision. Though primarily concerned with the nature of perception, it draws heavily from the history of philosophy of perception, and connects the concerns of analytical and continental philosophers.

While most interpreters take the opening of De Anima III 2 to be an oblique reference to some sort of conscious awareness, I argue that Aristotle intends to explain what I call ‘joint perception’: when conjoined with Aristotle’s subsequent claim that perceiving and being perceived are the same activity, the metaperception underpins the perception of a unified object. My interpretation is shown to have a more satisfactory account of the aporiai that follow. While I argue that the immediate focus of (...) the metaperceptual account is joint perception, it may also be applicable to other kinds of complex perception, which I briefly consider in the closing section.

In a passage of De Anima II, chapter 12, Aristotle makes a general claim about the senses, which is condensed in the formula that the senses are receptive of the sensible forms without the matter. While it is clear that this formula must play an important theoretical role in Aristotle’s account, it is far from clear what it exactly means. Its interpretation is still a focus of controversy among contemporary scholars. In this article the author presents the exegeses of this (...) formula proposed by the two most authoritative commentators on De anima from the second half of the thirteenth century, namely, Thomas Aquinas and Giles of Rome. Both commentators assume that with this formula and in particular with the qualification “without the matter” Aristotle intends to characterize an “intentional” reception of a form, and to contrast it with a “natural” reception, but they give different accounts of intentionality.

Averroes held the controversial thesis that there is only one separate material or possible intellect for all humans. This paper analyzes a passage from his Long Commentary on the De Anima which has been thought to constitute a primary philosophical argument for the view. It is called the Determinate Particular Argument, because it contends that the material intellect cannot be a determinate particular if it is to be the ontological receptacle of universal intelligible forms. After defending one crucial premise, it (...) will be shown how the key term “determinate particular” must be qualified to avoid an inconsistency with Averroes’s metaphysics and his position on the species membership of separate substances. Given this qualification in the face of competing views, the paper concludes that the Determinate Particular Argument should not be taken as a sufficient and independent argument for Averroes’s full thesis on the intellect.

I offer a novel interpretation of Aristotle's psychology and notion of rationality, which draws the line between animal and specifically human cognition. Aristotle distinguishes belief (doxa), a form of rational cognition, from imagining (phantasia), which is shared with non-rational animals. We are, he says, “immediately affected” by beliefs, but respond to imagining “as if we were looking at a picture.” Aristotle's argument has been misunderstood; my interpretation explains and motivates it. Rationality includes a filter that interrupts the pathways between cognition (...) and behavior. This prevents the subject from responding to certain representations. Stress and damage compromise the filter, making the subject respond indiscriminately, as non-rational animals do. Beliefs are representations that have made it past the filter, which is why they can “affect [us] immediately.” Aristotle's claims express ceteris paribus generalizations, subject to exceptions. No list of provisos could turn them into non-vacuous universal claims, but this does not rob them of their explanatory power. Aristotle's cognitive science resolves a tension we grapple with today: it accounts for the specialness of human action and thinking within a strictly naturalistic framework. The theory is striking in its insight and explanatory power, instructive in its methodological shortcomings. (shrink)

What in Aristotle corresponds, in whole or (more likely) in part, to our contemporary notion of predication? This paper sketches counterparts in Aristotle's text to our theories of expression and of truth, and on this basis inquires into his treatment of sentences assigning an individual to its kinds. In some recent accounts, the Metaphysics offers a fresh look at such sentences in terms of matter and form, in contrast to the simpler theory on offer in the Categories . I argue (...) that the Metaphysics initiates no change in this regard over the Categories . The point that form is (metaphysically) predicated of matter is a contribution, not to the account of statement predication, but to the analysis of compound material substances. Otherwise put, in our terms Aristotelian form is not - in particular, is not also - a propositional function, but a function from matter to compound material substances. (shrink)

The paper aims to show that Philoponus’ theory of sense-perception does not fit in with the spiritualist claim that the sensory process does not involve an extra material change in the sense-organ. Both the specific sense-organs and the primary sense-organ contract or expand in the perceptual process. On the other hand, the literalist claim needs to be modified as well since only the tactile sense-organ takes on the relevant qualities. Contraction or expansion in the sense-organ is triggered, not by physical (...) changes in the medium, but by the formal activities arising from the perceptible objects: colours make the visual sense-organ contract or expand. At the level of sense-organs, the physiological process underlying sense-perception has three stages. The change in specific sense-organ will be transmitted to the primary sense-organ of the particular sense , and then reaches the common sense-organ, the pneuma. The primary sense-organs are spatially distinguishable parts of the common sense-organ which is otherwise homogeneous, not allowing for qualitative differences. The homogeneity of the pneuma establishes the unity of sense-perception at the level of physiological processes. (shrink)

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)

In this paper I consider two related issues raised by Aristotle 's treatment of hearing and sounds. The first concerns the kinds of changes Aristotle takes to occur, in both perceptual medium and sense organs, when a perceiver hears a sounding object. The second issue concerns Aristotle 's views on the nature and location of the proper objects of auditory perception. I argue that Aristotle 's views on these topics are not what they have sometimes been taken to be, and (...) that when rightly understood they compare favourably in many respects with leading contemporary accounts.

Aristotle sometimes claims that the perception of special perceptibles by their proper sense is unerring. This claim is striking, since it might seem that we quite often misperceive things like colours, sounds and smells. Aristotle also claims that the perception of common perceptibles is more prone to error than the perception of special perceptibles. This is puzzling in its own right, and also places constraints on the interpretation of. I argue that reading Alexander of Aphrodisias on perceptual error can help (...) to make good sense of both of Aristotle’s claims. (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.

This paper aims to identify several interpretive problems posed by the final part of DA II.11, where Aristotle intertwines the thesis that a sense is like a ‘mean’ and an explanation for the existence of a ‘blind spot’ related to the sense of touch, adding the further contention that we are capable of discriminating because the mean ‘becomes the other opposite’ in relation to the perceptible property being perceived. To solve those problems, the paper explores a novel interpretation of Aristotle’s (...) claims, arguing that they describe a homeostatic physiological reaction by which the sensory apparatus responds to perceptible stimuli. According to the proposed interpretation, such homeostatic reaction constitutes a necessary condition for perceiving what Aristotle refers to as ‘proper’ perceptible features, which include properties like ‘hot’ and ‘cold’ as well as colors and sounds.

El debate acerca de la naturaleza de la percepción o aísthēsis en Aristóteles puede rastrearse ya en las obras de los comentadores antiguos. Desde hace un par de siglos, dos interpretaciones rivales se han posicionado como variantes extremas que nos aportan una concepción «literalista», o, por el contrario, «espiritualista», del fenómeno en cuestión. Sin embargo, ambas posturas coinciden en reducir la percepción a un asunto meramente «dado»: bien sea puramente fisiológico, o bien, únicamente intencional. Como consecuencia de ello, el dominio (...) conceptual resultaría separado de lo perceptual, algo que, según la célebre expresión de McDowell, representaría un punto de vista encantado por el «Mito de lo Dado». En este artículo defenderé una visión moderada del problema a través de una consideración sobre lo que podría denominarse el «espacio lógico» de la percepción, poniendo de relieve el papel conjunto y sintético de la diánoia en el discernimiento propio que implica todo proceso sensoperceptivo del alma específica del hombre. Si mi interpretación es correcta, difícilmente podría decirse que Aristóteles incurre en este tipo de mitología. (shrink)

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)

El presente artículo se enfrenta al problema clásico sobre cómo interpretar lo que Aristóteles, en de An. III, 5, denomina “el intelecto que produce todas las cosas”, llamado comúnmente intelecto agente. Históricamente, se han presentado dos lecturas: una, que se remonta a Alejandro de Afrodisia, que lo asocia con el motor inmóvil y con la divinidad y otra, asociada a Teofrasto pero que tiene en Filópono y St. Tomás de Aquino a sus principales representantes, que lo considera una facultad puramente (...) humana. Esta última interpretación ha sido históricamente la más sostenida; sin embargo, en tiempos recientes ha habido un resurgimiento de interpretaciones del intelecto agente como “divino”. Lo que queremos mostrar en este texto es que este resurgimiento se debe, más que a una reinterpretación del intelecto agente, a una comprensión diferente de la divinidad en la filosofía aristotélica, con características inmanentes y más próximas al intelecto humano.

Scholarship on Aristotle’s theory of visual perception has traditionally held that Aristotle had a single, static, conception of light and that he believed that illumination occurred prior to and independent of the actions of colours. I contend that this view precludes the medium from becoming actually transparent, thus making vision impossible. I here offer an alternative to the traditional interpretation, using contemporary conceptual tools to make good philosophical sense of Aristotle’s position. I call my view the ‘ecological’ interpretation. It postulates (...) two conceptions of light: non-visible mobile propagated light and visible static illumination produced by the interaction of propagated light with the environment’s coloured textured surfaces. I argue that these contemporary conceptual tools can find a foothold in and consistently enrich Aristotle’s extant position and that, with their aid, we can restore coherence to his theories of light and vision.

I argue that the science of the soul only covers sublunary living things. Aristotle cannot properly ascribe ψυχή to unmoved movers since they do not have any capacities that are distinct from their activities or any matter to be structured. Heavenly bodies do not have souls in the way that mortal living things do, because their matter is not subject to alteration or generation. These beings do not fit into the hierarchy of soul powers that Aristotle relies on to provide (...) unity to ψυχή. Their living consists in their activities, not in having a capacity for activity.

Many fragments from Theophrastus on perception are preserved by the late Neoplatonist, Priscian of Lydia. After preliminary source criticism concerning how to identify the fragments, I turn to Theophrastus’ discussion of perceiving and perceptual awareness. While he clearly rejects literalism, he also does not embrace “spiritualism”: he argues instead that we receive the defining proportions of perceptible qualities in the sense organ, though in different contraries than in the perceptible (thereby avoiding literalism). If Priscian’s report is faithful, Theophrastus also accepts (...) a moderate capacity reading of De anima III.2, locating awareness in a central monitoring sense, common to the individual modalities; and this has further implications for the unity of consciousness. Theophrastus’ method, though aporetic in form, is nonetheless a constructive engagement with the same texts of Aristotle’s we have ourselves, in the service of a joint research program in psychology that he shared with his colleague and former teacher.

According Aristotle's On the Soul, the first and most important form of sensation which we human beings share with other animals is a sense of touch. Without touch animals cannot exist. The first part of my article presents Aristotle's teaching about the internal connection between the soul and the sensory powers, especially as regards the sense of touch. The second part consists of a collection of the classical considerations about this subject. The third part then deals with the actuality of (...) some Aristotle's thesis about touch with reference to current research in neurophysiology on kinesthesia and haptic perception. (shrink)

In De Anima II 5, 417a21-b16, Aristotle makes a number of distinctions between types of transitions, affections, and alterations. The objective of this paper is to sort out the relationships between these distinctions by means of determining which of the distinguished types of change can be coextensive and which cannot, and which can overlap and which cannot. From the results of this analysis, an interpretation of 417a21-b16 is then constructed that differs from previous interpretations in certain important respects, chief among (...) which is its characterization of transitions from first potentiality to first actuality, e.g., learning, not as `ordinary', but rather as acquisitions of natural dispositions or faculties.

This dissertation explores Aristotle’s use of teleology as a principle of explanation, especially as it is used in the natural treatises. Its main purposes are, first, to determine the function, structure, and explanatory power of teleological explanations in four of Aristotle’s natural treatises, that is, in Physica (book II), De Anima, De Partibus Animalium (including the practice in books II-IV), and De Caelo (book II). Its second purpose is to confront these findings about Aristotle’s practice in the natural treatises with (...) the theoretical picture of the structure of teleological explanations gained from Aristotle’s theory of scientific demonstration. For this purpose a new interpretation of Analytica Posteriora II.11 is presented. This study thereby contributes to recent scholarship on the relation between Aristotle’s philosophy of science and his philosophy of nature, while at the same time adding to our knowledge of Aristotle’s notion of teleology in terms of its explanatory merits and limits.

This doctoral thesis addresses a group of conceptual instruments that are central to Aristotle's philosophy, namely, the concepts of pros hen, homonymy, synonymy and multivocity. These instruments are crucial to many of Aristotle's works as he devotes himself to analysing the key notions in each of his investigations using these instruments. Despite the undisputable importance of these instruments, they display severe interpretative problems, which this thesis critically evaluates. The currently established view on the relationship between homonymy and multivocity is discussed (...) and then reassessed in order to approach the definition of the so-called pros hen structure. This approach takes into account a so-far undescribed distinction of types of examples Aristotle uses and sheds new light on the assessments of the role of the pros hen structure in Aristotle’s philosophy and the theories on development in Aristotle’s thought. Niels Tolkiehn studied Philosophy and Systematic Musicology at the University of Hamburg.

Understanding the “intentionality” of mental phenomena is widely regarded as a key problem in philosophy of mind. Franz Brentano (along with his students, especially Edmund Husserl) is widely credited with bringing intentionality to philosophers’ attention. In early treatment by the Brentano school, intentionality is at least nominally understood as executed, brought about, or achieved in mental acts. And in the early 20th century, historians of psychology regarded this “act conception” of intentionality as integral for understanding the phenomenon. Yet the secondary (...) literature on Brentano and Husserl provides no clarification of mental acts as acts, and in contemporary philosophy, we have no workable account of what it could mean for intentionality to arise through mental acts. The main difficulty is that “act” is widely regarded as synonymous with “volitional personal action.” Since we as human agents certainly do not willfully bring about much of our own mental life, and since (on the standard analyses) all such volition presupposes intentionality, it is a mystery to work out what the act conception of intentionality could have amounted to. This dissertation is a systematic explication of the historical act concept of intentionality. Part I examines Brentano. I show that his early work on Aristotle’s psychology provides resources to think coherently about many mental phenomena as acts, even if they are not personal actions. However, I also show that Brentano’s mature psychology is not Aristotelian, at least insofar as it does not (and cannot) deploy an Aristotelian conception of mental acts. Part II examines Husserl. I show that Husserl’s mature transcendental phenomenology works with a robust and many-layered conception of mental acts, and that understanding intentionality as active is essential to the phenomenological viewpoint. Moreover, I argue that Husserl’s conception of mental acts can be viewed as a transcendentalized, neo-Aristotelian view. The results will be of special interest to historians of philosophy, but also have a much broader significance. Husserl’s view provides us with a model of what can be called an “internalist enactivism.” Any view along these lines represents a novel position that has not been articulated (or even considered) in contemporary debates.
