In Chapter 3 knowledge from sociocultural psychology is integrated with other disciplines within psychology such as cognitive, social, and neuro psychology, and outside psychology such as sociology, visual studies, and philosophy, to tackle the power of images to influence our seeing, thinking, feeling, and remembering.
Centring the devastating case of five-year-old Michael Komape’s drowning in a pit latrine at school, this chapter discusses the ‘dis/empowerment paradox’ inherent in South Africa’s ‘transformative constitutionalism’. Through the example of the Komapes’ 2018 case against the Minister of Basic Education (2018), it reveals the limitations of transformative constitutionalism rooted in Euro-American liberalism, which resonates with a neoliberal political economy that has failed to relieve the impoverished majority of their dehumanising precarity. While the chapter highlights the failure of the South African government to relate and respond to the suffering of the people it is meant to serve, more profoundly, it exposes the limitations of transformative constitutionalism due to its inability to even ‘see’ (let alone, validate) the world-sense of its majority population as legitimate law-sense. The Komape case thus reveals three key insights: (1) the resistance of private law to transformative ideals, (2) the reluctance of South Africa’s legal culture to embrace decolonial transformation and pluralism, and (3) the tension(s) between the legal consciousness of ordinary South Africans and the dominant legal culture. The case therefore underscores the need for Ntu Constitutionalism: a system grounded in indigenous normative priorities and robustly representative of South Africa’s marginalised communities and their needs.
Chapter 4, ‘The Efficacy of Empirical Vision’, argues that physical sight can and should lead to belief in John. Scholars often cite John 2:23; 4:48; and 20:29 as evidence for John’s own critique of physical seeing as a means of coming to belief. The chapter argues that close reading of John 2:23 and 4:48 reveals human hearts to be the true cause of unbelief and shows that physical sight is the catalyst for all unbelief and all belief. Neither does John 20:29 condemn sight as a means of acquiring belief. Rather, it suggests that mediated seeing – via the text of the Gospel – can be as efficacious for belief as an actual encounter with Jesus. The chapter concludes that sight is complex, but that no critique of the positive relationship between sight and belief exists in John.
Gerard Manley Hopkins, like many of his contemporaries, was drawn as a young man to the lively visual arts scene in London in the 1860s and 1870s. From a family of professional and amateur sketchers and illustrators, he initially considered a career as an artist. What, then, did Hopkins see? What pictures did he look at, and what did he sketch? How did the careful cultivation of his eye, under the formative influence of John Ruskin, shape his later life as a Jesuit poet? How do we get from a visual culture that Hopkins shared with many others of his time and place to the powerful originality of his mature poems? Analyzing evidence from Hopkins’s surviving sketches, letters, and journals, this chapter explores the effects of Hopkins’s visual education on the language, the prosody, and the shaping force of grace in the poems.
This chapter covers Mesoamerican conceptions of knowledge through the image of seeing. Knowledge is a matter not just of accessing stable and mind-independent truths about the world, but also involves an aspect of creativity and construction, according to Mesoamerican views. Knowledge requires sensation, which has a creative and participative aspect. We contribute to sensation as active partners with the world. The chapter discusses seeing, the rituals and texts associated with seeing, and the community of people, such as the daykeepers in the Maya tradition, tasked specifically with generation and transmission of knowledge.
The shape and form of boundary walls around and within Greek sanctuaries, and the impact those boundaries had on the experience of the ritual happening within, have attracted little scholarly attention, especially in comparison to work on the powerful impacts of other elements of sanctuary architecture, and architecture more widely. This article, using the case study of the high temenos walls and those of the Telesterion temple structure of the sanctuary of Demeter and Kore at Eleusis, explores the active impact these walls had on particularly the sight- and sound-scapes engaged with by participants. As such it argues for the crucial importance of these walls at Eleusis in creating the intensity, emotion, power, and conviction of the ritual experience of the Mysteries for participants.
This chapter takes Dickinson as its first case study to examine how figures such as a robin or a pine can map out partial ecological relations that allow for survival. As her poetic and scientific engagement shows, understanding species as figures reveals both their material and speculative potential—what is termed their disjunct specificity since a literary figure can be understood to have both a material or literal ground and a metaphorical meaning. As figures, species are partially empirical matter (as the successive biological reproduction of individuals) and partially subjective concepts (as idealized or defined “types”). The chapter first examines the scientific problem that disjunct species presented, where similar species appeared in widely disparate geographical regions, prompting investigations by scientists such as Asa Gray and Louis Agassiz about whether or how these species could be biologically and spatially related. Moving from their observations to Dickinson’s poetic-empirical observations, the partiality of her gaze reveals a sense of species engaged with current discussions of biological species, but also significantly more diminutive. This “species” reveals ecological relation to be figural and partial, based upon a certain slippage between some material that holds while the earth, sky, and even body shifts, departs, disperses.
Kuhn used the duck–rabbit figure as a metaphor for revolutionary change in science. The two aspects of the drawing stand for two ways of perceiving the world, before and after a revolution, while the drawing itself represents the world that, paradoxically, both changes and remains the same. I argue that Kuhn, aiming to bring about a revolution in philosophy of science, did not want to eliminate the paradox, but rather to exploit and underscore it to challenge what he saw as the dominant epistemological paradigm. I also argue that Kuhn rejected the two-tiered view of perception, first observing and then interpreting raw data, in favour of the theory-ladenness of observation that echoed Wittgenstein’s account of ‘seeing’ rather than Hanson’s assimilation of scientific observation to ‘seeing as’. According to Wittgenstein, ‘seeing as’ is parasitic upon regular seeing and, in that sense, cannot illuminate the general case of perception in science. Finally, I show that the analogy between the dawning of an aspect and novelty in science, informed Kuhn’s views on creativity. In his view, advances in science emerge when a system of beliefs is transformed by new patterns of organization.
This chapter examines Philo's views of exile and eschatology and his use of Israel terminology. The first part of the chapter argues that despite his tendency towards allegory, numerous places in the Philonic corpus suggest that Philo viewed the exile as ongoing and—like Josephus—looked forward to a future restoration of Israel. The second part of the chapter shows that Philo avoids the term "Israel" when referring to his contemporaries, whom he calls Ioudaioi ("Jews"), while "Israel" appears in other contexts and correlates closely with his eschatological statements. Like Josephus, Philo argues that Israel's restoration will come through divine initiative rather than violent revolution, and the first element of that restoration will be a divinely initiated return to virtue and obedience. Remarkably, Philo also suggests that not all Jews are or will be included in "Israel," a view that reflects sympathy with a prophetic or sectarian view of Israel in which Israelite status is contingent on proper obedience to God.
Whereas the rhetoric of new media at the turn of the millennium stressed the evolution from ‘seeing’ to ‘being’, artists who were most involved in the early stages of virtual reality have moved from the overoptimistic and perhaps almost hubristic notion of ‘being’ as an existential condition of virtual reality, to a far more realistic, humble and ecologically oriented notion of ‘being-in-common’. This contribution looks at two artists in particular – Char Davies and Gary Warner – and the focus of their current work.
Recent seeing measurements at the Anglo-Australian Telescope (AAT) point towards the thermal characteristics of the telescope itself, in particular the temperature difference between the mirror and the dome air, as the most important factor degrading the seeing, more so than the temperature difference between the inside and outside air. We present the findings, propose clarifying experiments, and discuss possible remedies. We set the realistic target for the AAT to achieve median seeing of 1·5″ rather than the current 1·8″.
Seeing measured in the open air with a differential image motion monitor (DIMM) is compared with seeing measured simultaneously at the Cassegrain focus of the Anglo-Australian Telescope (AAT). It is shown that when the mirror is hotter than the dome air, the AAT’s seeing is degraded by ~1 arcsec per Celsius degree of excess mirror temperature. The consequence of this is that mirror seeing currently contributes significantly to the seeing at the AAT on many nights. A mirror colder than the dome air does not seem to degrade seeing, and neither does an internal-to-external air temperature difference of up to at least 3°C when the venting fans are on.
Site-testing measurements by the Australian group has already shown that Dome C on the Antarctic plateau is one of the best ground-based astronomical sites. Furthermore, Dome A, the Antarctic Kunlun Station, as the highest point on Antarctic inland plateau, where a Chinese Antarctic scientific expedition team first reached in 2005, is widely predicted to be an even better astronomical site by the international astronomical community. Preliminary site-testing carried out by the Center for Antarctic Astronomy (CAS) also confirms Dome A as a potential astronomical site. Multi-aperture scintillation sensors (MASS) can measure the seeing and isoplantic angle, the turbulence profile, etc., which are very important site-testing parameters that we urgently need. The MASS site testing at Dome A is presented here, and includes the method of processing data and the hardware for the extreme conditions of Dome A, Antarctica.
From theoretical analysis and site testing work for 4 years on Dome A, Antarctica, we can reasonably predict that it is a very good astronomical site, as good as or even better than Dome C and suitable for observations ranging from optical to infrared & sub-mm wavelengths. After the Chinese Small Telescope ARray (CSTAR), which was composed of four small fixed telescopes with diameter of 145mm and the three Antarctic Survey Telescopes (AST3) with 500mm entrance diameter, the Kunlun Dark Universe Survey Telescope (KDUST) with diameter of 2.5m is proposed. KDUST will adopt an innovative optical system which can deliver very good image quality over a 2 square degree flat field of view. Some other features are: a fixed focus suitable for different instruments, active optics for miscollimation correction, a lens-prisms that can be used as an atmospheric dispersion corrector or as a very low-dispersion spectrometer when moved in / out of the main optical path without changing the performance of the system, and a compact structure to make easier transportation to Dome A. KDUST will be mounted on a tower with height 15m in order to make a full use of the superb free atmospheric seeing.
Sites on Antarctic plateau have unique atmospheric properties that make them better than any mid-latitude sites as observatory locations. From site testing measurements over 4 years on Dome A carried out by the Chinese Center for Antarctic Astronomy, we can reasonably predict that Dome A is as good as or even better than Dome C, which has been proved to be the best astronomical site by now, and suitable for high angular resolution observations. Seeing monitoring is necessary for planning large scale ground-based optical astronomical telescopes. In 2012, the 28th Chinese Antarctic Scientific Expedition carried out preliminary daytime seeing monitoring using a Differential Image Motion Monitor (DIMM) placed at a height of 3.5m. The median seeing was found to be 0.8″. This will be the foundation of future research that obtains comprehensive and long-period monitoring of the site's optical parameters.
Vision is used in nearly all aspects of animal behavior, from prey and predator detection to mate selection and parental care. However, the light environment typically is not uniform in every direction, and visual tasks may be specific to particular parts of an animal’s field of view. These spatial differences may explain the presence of several adaptations in the eyes of vertebrates that alter spectral sensitivity of the eye in different directions. Mechanisms that alter spectral sensitivity across the retina include (but are not limited to) variations in: corneal filters, oil droplets, macula lutea, tapeta, chromophore ratios, photoreceptor classes, and opsin expression. The resultant variations in spectral sensitivity across the retina are referred to as intraretinal variability in spectral sensitivity (IVSS). At first considered an obscure and rare phenomenon, it is becoming clear that IVSS is widespread among all vertebrates, and examples have been found from every major group. This review will describe the mechanisms mediating differences in spectral sensitivity, which are in general well understood, as well as explore the functional significance of intraretinal variability, which for the most part is unclear at best.
Contemporary interpretations of phenomenology, as well as current theories of perception, define perception (and seeing) in terms of sense. This chapter brings out certain difficulties for the idea of perceptual sense, difficulties raised by Wittgenstein (and Austin). These difficulties come from the specific point of view of ordinary language philosophy. Talk of perceptual sense takes its start in Frege's notion of sense. This notion was the basis for the so-called Fregean readings of phenomenology. The criticisms in Austin's Sense and Sensibilia, though leveled directly at traditional empiricism, are perhaps even more useful today, now that a whole analysis of perception has been worked out in terms of sense. A phenomenon is not a symptom or a sign of something else that is real: on this point, Wittgenstein and Austin agree. Wittgenstein shows that the myth of seeing as an activity is bound up with a myth of seeing as passivity.
The limitation to ground based astronomy is the Earth's atmosphere. The atmosphere above the Antarctic plateau is fundamentally different in many regards compared to the atmosphere at temperate sites. The extreme altitude, cold and low humidity offer a uniquely transparent atmosphere at many wavelengths. Studies at the South Pole have shown additionally that the turbulence properties of the night time polar atmosphere are unlike any mid latitude sites. The lack of high altitude turbulence combined with low wind speeds presents favorable conditions for interferometry. More recent site testing at Dome C has revealed the most superb seeing of any site tested. The unique properties of the polar atmosphere can be exploited for Extra-solar Planet studies with differential astrometry, differential phase and nulling interferometers.
A variety of observations have been made of solar features (sunspots, faculae, the limb) using both array and single element scanning techniques. The telescope was the 1.6 m McMath-Pierce on Kitt Peak. Array data were acquired with a 58×62 pixel Si:Ga detector at 4.8, 7.8, 12.4, and 18 μm, while a CCD camera recorded the same image position at 0.5 μm. In a separate experiment, a nutating mirror device was used to generate a raster scan of solar disk areas, the output being fed to a Si PIN diode (0.5 μm filter) and a As:Si diode (12.4 μm filter). The scanner data yield simultaneous images at the two wavelengths and was essentially a repeat of the 1970 Turon-Léna experiment with updated equipment. Examples of images at the various wavelengths are given in the poster. Analysis of the data is incomplete at this time. We can report that the effects of seeing were encountered at all wavelengths, including 18μm, even though conditions were deemed good at times (for example, penumbral filaments were resolved in sunspots). We have thus been unable to verify, as yet, the conditions reported by Bester et al, in which exceptional seeing is realized in the infrared.
Adaptive optics systems are now being developed for astronomical applications. On large telescopes, a substantial image improvement can be obtained in the near infrared, using natural guide stars.
