David Marr (1982) What does it mean to see? The plain man's answer would be, to know what is where by looking. David Marr (1982) Theories of Vision: From Pythagoras to Marr The emission theory The eye obviously has fire within it, for when the eye is struck fire flashes out. Pythagoras Alcmaeon of Croton (ca. 450 BCE) Euclid Empedocles Surprisingly enough … We have shown that many college students believe in visual extramissions, as shown by a variety of measures and probes, and what we find most significant and surprising is that this belief is extremely resistant to standard educational experiences that seem as though they should counteract the misunderstanding. The intromission theory There are what we call images of things stripped off the surface layers of substances like membranes—these fly to and fro in air. Lucretius, On the Nature of Things (De Rerum Natura) Democritus Epicurus Lucretius (460–360 a.C.) Plato’s view Accordingly, whenever there is daylight round about, the visual current issues forth, and coalesces with the daylight and is formed into a single homogeneous body in direct line with the eyes Plato, Timeus After centuries … The most serious problem facing the Muslim heirs of Greek thought was the extraordinary diversity of their inheritance. Among theories of optics, for instance, Muslim thinkers had the following choice: • the emission theory of sight of Euclid and Ptolemy, which postulated visual rays emanating from the observer's eye; • the older Epicurean intromission theory, which reversed the rays and made them corporeal; • the combined emission-intromission theories of Plato and Galen; • some enigmatic statements of Aristotle about light as qualitative change in a medium. -

David Lindberg. Theories of Vision from Al-Kindi to Kepler. Chicago: University of Chicago Press, 1976
378 BOOK REVIEWS has moved Dr. Stocking to condescension and disdain; ignoring many important matters, he reaches into the Acknowledgements to remark sourly upon my wife’s finding Rivers’s grave. No wonder I was “posing somberly” beside it. Foreboding, perhaps. Apart from natural objections to various comments by the reviewer, I should like to make a couple of specific corrections. Rivers did not die in his rooms; nor am I an American student of the Inuit. I am a Canadian who has worked among Northern Athapaskans. Mere details, but perhaps suggesting, along with other considerations, that W. H. R. Rivers was “skimmed” rather than read carefully by the reviewer. David Lindberg. Theories of Vision from Al-Kindi to Kepler. Chicago: University of Chicago Press, 1976. 324 pp. (Reviewed by ROBERTJ. RICHARDS) The early history of visual perception is labyrinthian, but its many turns should be of considerable interest to the historian of science. That history, in one of its aspects, ex- hibits a heritage of mathematical and physical inquiry only a little less endowed than astronomy in refinement of its technical concepts; indeed, many associated with impor- tant advances in mathematics and astronomy also made significant contributions to op- tics: for example, Euclid, Archimedes, Ptolemy, Alhazen, Kepler. Anatomical and physiological investigations of vision by ancient, medieval, and Renaissance physicians constitute another distinguishable tradition in the early history of perception. The natural philosophers-the Atomists, Platonists, Aristotelians, Stoics, along with their descendants-make up a third group proposing theories of light propagation, sensory operation, and cognitive interpretation of visual images. -

Ibn Al-Haytham and Scientific Method
IBN AL-HAYTHAM AND SCIENTIFIC METHOD A Dissertation submitted to the Faculty of the Graduate School of Arts and Sciences of Georgetown University in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Islamic Studies By Sohrab Ghassemi, M.A. Washington, DC March 3, 2020 Copyright 2020 by Sohrab Ghassemi All Rights Reserved ii IBN AL-HAYTHAM AND SCIENTIFIC METHOD Sohrab Ghassemi, M.A. Thesis Advisor: Jonathan A.C. Brown, Ph.D. ABSTRACT This examination into the history of Arabic science explores the methods utilized by Ibn al-Haytham for his scientific investigations. Specifically, this study compares and contrasts his approach towards establishing the equal angles law of reflection for light in chapter three of book four of his Kitāb al-Manāẓir, or The Book of Optics, with the approach taken by him in his maqālat-u fī mā'īyat-i al- athar-i alladhī fī wajh-i al-qamar-i, or "Treatise on the Nature of the Marks on the Surface of the Moon." The analysis focuses upon his technical usage of the word i‘tibār, and its variants, in order to arrive at the finding that his most advanced method for inquiry into the natural world did not constitute full experimental testing in the sense of the modern scientific method, but rather can best be understood as a type of controlled observation that yet still goes beyond the ancient Greek idea of empeiría (empiricism). Further, when he was able to utilize instrumentation for his research, he also achieved a science of demonstration (apódeixis) with an emphasis upon the repeatability of his findings. -
ISSA Proceedings 2014 – Fine Arts As Visual Argument
ISSA Proceedings 2014 – Fine Arts As Visual Argument: Optical Argument In Discourse, Technology And Paintings* Abstract: This essay performatively critiques seventeenth-century Dutch visual culture to offer an alternative way of understanding visual argument. The formation of optical discourse is rhetorically analyzed, and a focus is given to how the relationships among paintings, knowledge and technology are rhetorically subverted, transformed and maintained along with a pre-text of optical controversy. As visuality is historically and culturally constituted, its constitution is practiced in and by argumentative discourse of optics and technology. Keywords: camera obscura, controversy, excess, extramission theory, iconophobia, intromission theory, Johannes Kepler, optics, retinal image, seventeenth-century Dutch visual culture. 1. Introduction Recent scholarship on visual argument in the field of argumentation theory has produced some fruitful areas to explore in order to re-conceptualize the relationship between verbal texts and visual images. George Roque’s argument offers a promising starting point. Roque (2010) argues that it is time for visual argumentation to self-reflect this emerging field and to start conferring a thorough definition, after having grounded a legitimacy of its scholarship by collective demonstrations of numerous cases for visual arguments ever since its incipient recognition of the field. Specifically, he points out the disciplinary problem in which the visual is singled out as a means of communication to display -

CATEGORICAL LY REJECTI NG THE PLENUM : THE PHILOSOPHICAL FOUNDATIONS FOR GENUINE SCIENCE Mark J. Lofts Abstract Present - day science remains tainted by the notion of the plenum and particularly by its inconsistent rejection, especially by Einstein ’s Relativity . Yet a categorical rejection of the plenum in all its manifestations is necessary for the proper understanding of the nature of light. Under modernity, t h ere is no recognition of Galileo’s singular achievement in negating the universal plenum – and even the atomic plenum – as against the plenum - soaked theorizing of Descar tes . The difficulty of removing the plenum is magnified by its intimate connection to the pleroma , an all - embracing all - controlling divine sanction or harmony which ‘ links ’ religion to science in a covert manner. With the ontological understanding of the absolute difference between matter, space and time, the plenum is abolished through understanding the nature of subatomic particles as vortices, inherently nonlocal as they are not point - particles but possess extension in space. Not only is matter infini tely divisible, denying singularities, but the Doppler Effect is shown to be fundamental to the motion of light. The arguments advance via the insights of Fehrenbach and Ritz towards the insight of Herbert Dingle’s question as to the nature of light emiss ion and absorption by objects in mutual motion.

Submitted HAL, 14 December 2019 Grosseteste's Law of Refraction Amelia Carolina Sparavigna Department of Applied Science and Technology, Politecnico di Torino, Italy Robert Grosseteste was one of the most prominent thinkers of the Thirteenth Century. In the framework of the Aristotelian physics and under the influence of a Neoplatonic outlook, Grosseteste wrote several scientific treatises, mainly concerning some problems of optics, acoustic and the causes of heat. Here we discuss the laws of reflection and refraction of light, as proposed in one of his treatises, the De Iride. In particular, we will consider his law of refraction. Keywords: History of Science, History of Physics, Optics. Robert Grosseteste (c.1175 – 1253) was one of the most prominent thinkers of the Thirteenth Century. Philosopher and scientist, he was Bishop of Lincoln from 1235 to 1253. Grosseteste drew from Augustine his Neoplatonic outlook; in his philosophical thought, he made also extensive use of the works of Aristotle, Avicenna and Averroes. -
The Deceit of the Senses: Sight and the Mirror
Giuseppe Veltri The Deceit of the Senses: Sight and the Mirror According to Pyrrho, as is transmitted by Aristocles via Eusebius of Caesarea, knowl- edge acquired through the senses is neither true nor false: “Now he says that Pyrrho shows that objects are equally indifferent and unfathomable and undeterminable because neither our senses nor our judgements are true or false.”1 If our senses and therefore our judgments do not fulfil the criteria of the Aristotelian principle of con- tradiction, being neither true nor false, they are either equipollent or insufficient for perception. The suspension of judgment is not only logical but also necessary. According to the Pyrrhonian Sextus Empiricus, the main argument for necessary invalidation of knowledge is “disagreement”2 because of the difference of the senses,3 for it is obvious to him that senses differ from one another. He also quotes some exam- ples of discrepancies in perception. Sextus does not question the fact that an object could show the quality of what it is appears to be (“it is possible to say what they appear to be like on any given occasion”).4 However, we are not seeking the percep- tion of the object in its appearance in a particular moment and in a particular space, but the perception according to its real nature. For then the object does not “natu- rally” have any qualities. Each of the phenomena perceived by the senses seems to be a complex: the apple, for example, seems smooth, odorous, sweet, and yellow. However, it is not clear whether it really possesses these qualities, -
