Guthrie: Tratado 29 (IV, 5, 8) – A WORLD OUTSIDE OF OUR WORLD WOULD NOT BE VISIBLE
A WORLD OUTSIDE OF OUR WORLD WOULD NOT BE VISIBLE. 8. If there were a body outside of our world, and if an eye observed it from here without any obstacle, it is doubtful that the eye could see that body, because the eye would have no affection common to it; for community of affection…

Guthrie: Tratado 29 (IV, 5, 7) – DOES THE WITHDRAWAL OF THE LUMINOUS SOURCE ABANDON THE LIGHT TO DESTRUCTION
DOES THE WITHDRAWAL OF THE LUMINOUS SOURCE ABANDON THE LIGHT TO DESTRUCTION; OR DOES THE LIGHT FOLLOW IT? 7. It might be asked whether the withdrawal of the object from which light emanates abandons the light to destruction, or does the light follow the source into withdrawal? This question is related to the former one;…

Guthrie: Tratado 29 (IV, 5, 6) – THE RELATION OF THE AIR TO THE LIGHT
THE RELATION OF THE AIR TO THE LIGHT. 6. Could light exist without air, if the sun illuminated the surface of bodies, and if there were a void in the interval which is accidentally illuminated by virtue of its location (between the sun and the bodies) ? It is certain that if the other things…

Guthrie: Tratado 29 (IV, 5, 5) – NEITHER FOR HEARING IS THE AIR NECESSARY AS A MEDIUM
NEITHER FOR HEARING IS THE AIR NECESSARY AS A MEDIUM. 5. As to hearing, there are several theories. One is that the air is first set in motion, and that this motion, being transmitted unaltered from point to point from the (location of the) sound-producing air as far as the ear, causes the sound to…

Guthrie: Tratado 29 (IV, 5, 4) – MUTUAL RELATION OF THE EYE’S LIGHT AND THE OBJECTIVE LIGHT
MUTUAL RELATION OF THE EYE’S LIGHT AND THE OBJECTIVE LIGHT. 4. What is the mutual relation between the light that emanates from the eye, and the light which is exterior to the eye, and which extends between the eye and the object? Light has no need of air as a medium, unless indeed somebody should…

Guthrie: Tratado 29 (IV, 5, 3) – USELESSNESS OF AIR AS TRANSMITTING MEDIUM
USELESSNESS OF AIR AS TRANSMITTING MEDIUM PROVED FROM SIGHT OF OBJECTS AT NIGHT. 3. A strong proof that the forms of sense-objects are not seen merely because the air, on being affected, transmits them by relays from point to point, is that even in darkness the fire, the stars, and their forms may be seen.…

Guthrie: Tratado 29 (IV, 5, 2) – NECESSITY OF A MEDIUM IN THE THEORIES OF VARIOUS PHILOSOPHERS
NECESSITY OF A MEDIUM IN THE THEORIES OF VARIOUS PHILOSOPHERS. 2. If vision presupposes the union of the “light of the eye,” with the light interposed (between the eye) and the sense-object itself, the interposed medium is the light, and this medium is necessary, on this hypothesis. (On the theory of Aristotle) the colored substance…

Guthrie: Tratado 29 (IV, 5, 1) – IT IS UNCERTAIN WHETHER AN INTERMEDIARY BODY BE IMPLIED BY VISION
IT IS UNCERTAIN WHETHER AN INTERMEDIARY BODY BE IMPLIED BY VISION. 1. Above we suggested the question whether it be possible to see without some medium such as the air or a diaphanous body; we shall now try to consider it. It has already been asserted that in general the soul cannot see or feel…

Bouillet: Tratado 29 (IV, 5) – QUESTIONS SUR L’ÂME, III
(I-II) La perception de l’étendue tangible suppose contact entre le corps et l’objet extérieur. En est-il de même pour la vue et pour l’ouïe ? Y a-t-il un milieu entre l’œil et l’objet visible, entre l’oreille et l’objet sonore ? S’il y a un milieu entre l’œil et l’objet visible, ce milieu n’est pas affecté,…

MacKenna: Tratado 29,8 (IV,5,8) — Luz e Corpo Exterior
8. Imagine that beyond the heavenly system there existed some solid mass, and that from this sphere there was directed to it a vision utterly unimpeded and unrestricted: it is a question whether that solid form could be perceived by what has no sympathetic relation with it, since we have held that sympathetic relation comes…
