Aristotle’s broad characterization of the soul has been challenged on account of its reliance on the notion of a “potentially alive body”. J. L. Ackrill famously claimed that no body can meet this description without being already actually alive. By a close inspection of both metaphysical and embryological texts, this paper argues that (1) it is embryos (and not fully-formed organic bodies) who provide the right kind of potentially alive subjects and that (2) the schematic character of the soul’s common (...) formula accounts for its seemingly intractable features. It also holds that (3) once the homonymous nature of life is brought into the picture, the κοινότατος λόγος appears unproblematic – at least for some of its most troublesome instances. (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)
