"Aristotle's Physics Book 3 covers two subjects: the definition of change and the finitude of the universe. Change, which enters into the very definition of nature as an internal source of change, receives two definitions in chapters 1 and 2, as involving the actualization of the potential or of the changeable. Alexander of Aphrodisias is reported as thinking that the second version is designed to show that Book 3, like Book 5, means to disqualify change in relations from being genuine (...) change. Aristotle's successor Theophrastus, we are told, and Simplicius himself, prefer to admit relational change."--BOOK JACKET. (shrink)

The paper examines three innovative issues in the Byzantine commentator which seem to reflect his own views on the common sense power. First, he perceives a gap in Aristotle’s explanation of the double nature of representational images. He points to the common sense power as the factor responsible for our ability to connect representational images to things represented by them. This kind of activity is called additional perception. Second, the identification of the common sense power with touch can be explained (...) with reference to the thesis that animal life is a life of perception and touch is the principle of this life. It may lead to the conclusion that the basic pattern of all sense perception is to be equated with the general way that touch works. Third, Michael endorses the view that the regulative force of the common sense power extends to the ability to stop the individual senses working altogether, as it is clear from the explanation of sleep. In this process, the role of sense organs—both those of the individual senses and the first sense organ—is especially important, which—along with other observations—allows us to conclude that the Byzantine commentator is committed to hylomorphic explanations.

The aim of this paper is twofold. First, it may be clear that ears play a role quite different from that of the other sense-organs. Unlike the eyes, nose and tongue, ears cannot be called genuine sense-organs. They only transmit the blow in the air to the brain and the blood in the head that receive the blow. Second, since hearing is defined as a motion extending from the brain to the region around the liver, there is a possibility to (...) assume that the same sound can be grasped by the rational and the appetitive parts of the soul. It gives rise to different emotions: joy in the wise and pleasure in the fool. Furthermore, if sound affects the brain and through the brain it reaches the rational soul, then one may suppose that human reason is open to direct influences from the sensible world and plays a central role in sense-perception.

The paper aims to show that ανoια is the general term for the diseases of the soul, and that μανία and αμαϑία are not necessarily two distinct species but two levels of the same disease: ignorance signifies the cognitive state, whereas madness indicates both a cognitive state and a specific phenomenal character. Plato's other remarks on psychic ailments can be incorporated into this account. The result can also be accommodated to the general theory of the soul–body relationship in the dialogue. (...) Incarnated souls cannot work without the corresponding activity of the body, even if this does not rule out the possibility for the soul to exist in a discarnate state. (shrink)

It has been strongly disputed that Philoponus is the author of the commentary on the third book of De Anima printed in vol. xv of CAG under his name, and Stephanus of Alexandria has been taken to be its real author. The evidence for the authorship of Stephanus is as follows: Codex Parisinus gr. 1914, written in the twelfth century, has an adscript by a later hand saying βιβλ⋯ον τρ⋯τον ⋯π⋯ ϕωνης στεϕ⋯νου, and the same appears in the fifteenth-century Codex (...) Estensis iii F 8. In 543.9 there is a clause saying ὡς ⋯ν τῷ περ⋯ ⋯ρμηνε⋯ας ⋯μ⋯θομεν, which was taken by M. Hayduck to be direct reference to Stephanus' commentary on the De Interpretatione, edited also by Hayduck in vol. xiii/3 of CAG. The third book, says Hayduck, is short and jejune, in contrast to the verbosity of the preceding two books. The commentary on the third book of De Anima is divided into lectures, but the first two books are not. Some locutions are used constantly in the third book and in Stephanus' in De Interpretatione as well. In the Codex Vaticanus gr. 241 fol. 6 we are told that Stephanus also wrote a commentary on the De Anima. (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)

: By examining the passage on virtues in the Epinomis, possibly by Philip of Opus, I aim to show that the ethical theory expounded there differs both from the account of the Laws and from the notions we find in the fragmentary evidence concerning the Old Academy. Unlike the account in the Laws the unity of virtue is provided, not by justice, but by piety interpreted as a virtue involving mathematics, especially astronomy. The peculiar importance of mathematics in virtue is (...) not attested in any of the other authors of the Old Academy. (shrink)

Emotions are characteristic activities/states in hylemorphic structure of the Aristotelian soul. Emotional activities/states are physiological processes/states as well, as it is particularly clear in anger. It raises the question about the origin of their intentionality. Sometimes sheer bodily processes can lead to emotions, which implies that intentionality in emotions might also originate in bodily processes. But Aristotle does not generalize this point in saying that all emotions are due to bodily processes. Moreover, since they are complex phenomena, involving opinion, representation, (...) desire, pleasure and pain, their intentional nature must also be a certain amalgamate of the intentionality of the ingredients. It involves that the relevant kinds of pleasure and pain are also intentional states. On the other hand, besides establishing certain general similarities Aristotle does not seem to have worked out a unifi ed theory of emotions. To mention but one well-known example, most of the emotions he discusses in detail are based on representation, whereas hatred is supported by a general statement. (shrink)

A Review of Gabriela Roxana Carone, Plato’s Cosmology and its Ethical Dimensions, Cambridge University Press, Cambridge, 2005.

Le présent texte discute les méthodes utilisées par Philopon et Pseudo-Simplicius lorsqu’ils commentent la théorie de la perception sensible d’Aristote, et il marque leurs différences. Philopon fait un fréquent usage de théories médicales et de matériel empirique, empruntés principalement à Aristote, afin de mettre en lumière non pas seulement les activités des différents sens, mais aussi une certaine conscience ainsi que la façon dont nous expérimentons nos états intérieurs. Par contre, son contemporain Athénien, Pseudo-Simplicius, méconnaît complètement de tels aspects. Sa (...) méthode est déductive: il fait appel à une thèse générale, empruntée en partie à Iamblichus, dont il déduit des thèses relatives à la perception sensible. L’accent est mis ici sur la doctrine de Philopon, car son recours à des perspectives médicales donne lieu à un mélange intéressant de théories platoniciennes et de théories médicales empiriques.

Aristotle’s notion of experience occupies an important place in his account of scientific understanding and its methodology. It is linked, not only to sense-perception and the principles of skill and scientific understanding, but also, methodologically, to ἐπαγωγή. Due to its various involvements it has a complex job to perform. Such a complexity – or Janus-face – gives rise to many questions concerning its status and content. Many of these questions were raised in later antiquity. In the introductory part of the (...) paper I shall give a very brief summary of Aristotle’s notion of experience, concentrating on issues that will be relevant next, and then discuss the explanation we find in a commentary which has come down to us under the name of Philoponus. I do it in the hope that the discussion sheds light on novelties in the commentator’s approach which deserve attention. (shrink)
