Synaesthesia is a condition in which one type of stimulation evokes the sensation of another, as when the hearing of a sound produces photisms, i.e. mental percepts of colours. R is a 20 year old colour blind subject who, in addition to the relatively common grapheme-colour synaesthesia, presents a rarely reported cross modal perception in which a variety of visual stimuli elicit aura-like percepts of colour. In R, photisms seem to be closely related to the affective valence of stimuli and (...) typically bring out a consistent pattern of emotional responses. The present case study suggests that colours might be an intrinsic category of the human brain. We developed an empirical methodology that allowed us to study the subject's otherwise inaccessible phenomenological experience. First, we found that R shows a Stroop effect elicited by photisms despite the fact that he does not show a regular Stroop with real colours. Secondly, by manipulating the colour context we confirmed that colours can alter R's emotional evaluation of the stimuli. Furthermore, we demonstrated that R's auras may actually lead to a partially inverted emotional spectrum where certain stimuli bring out emotional reactions opposite to the normal ones. These findings can only be accounted for by considering R's subjective colour experience or qualia. Therefore the present paper defends the view that qualia are a useful scientific concept that can be approached and studied by experimental methods. (shrink)

In a variety of synaesthesia, photisms result from affect-laden stimuli as emotional words, or faces of familiar people. For R, who participated in this study, the sight of a familiar person triggers a mental image of "a human silhouette filled with colour". Subjective descriptions of synaesthetic experiences induced by the visual perception of people's figures and faces show similarities with the reports of those who claim to possess the ability to see the aura. It has been proposed that the purported (...) auric perception may be easily explained by the presence of a specific subtype of cross-modal perception. We analyse the subjective reports of four synaesthetes who experience colours in response to human faces and figures. These reports are compared with descriptions of alleged auric phenomena found in the literature and with claims made by experts in esoteric spheres. The discrepancies found suggest that both phenomena are phenomenologically and behaviourally dissimilar. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Confucian Liberalism: Mou Zongsan and Hegelian Liberalism by Roy TsengMilan Matthiesen (bio)Confucian Liberalism: Mou Zongsan and Hegelian Liberalism. By Roy Tseng. Albany: SUNY Press, 2023. Pp. 405. Hardcover $95.00, isbn 978-1-4384-9111-0.With Confucian Liberalism, Roy Tseng sets a new landmark in the contemporary discourse on Confucian political theory. His intricate account of the political philosophy of Mou Zongsan 牟宗三 (1909–1995) and other New Confucian philosophers, in conjunction with his (...) study of T.H. Green's (1836–1882) and other British idealists' liberalism, offer a fresh and novel approach to Confucianism and liberalism alike. Throughout the eight chapters of his book, Tseng develops the concept of "Confucian liberalism." This concept stays faithful to civil liberties, but grounds democracy on an ethics of self-realization and a perfectionist ideal of the state, "where the government helps the people to 'attain accomplishment according to the individual's nature' (jiu geti er shuncheng 就個體而順成)" (p. 125). On the one hand, this framework attempts to circumvent the overbearing tendencies of traditional Confucianism, whose moral imperatives had prohibited the development of an independent sphere of politics. On the other hand, it reintroduces the Confucian concept of humaneness (ren 仁) as an answer to the lack of common meaning in modern societies. On the one hand, Tseng therefore dissociates himself from anti-Confucian liberals such as Yin Haiguang 殷海光 (1919–1969) or Zhang Foquan 張佛泉 (1907–1994), who had proclaimed the incompatibility of Confucianism and liberal values. On the other hand, he also differentiates himself from what he calls "antiliberal Confucians." Especially recently, the latter have attracted much attention by proposing a political vision opposed to the perceived foreign and "Western" concept of liberalism. Under labels such as "political Confucianism" (Jiang Qing 蔣慶), "socialist Confucianism" (Chen Lai 陳來), "politics of benevolence" (Kang Xiaoguang 康曉光), "Confucian meritocracy" (Bai Tongdong 白彤東), or "Confucian political perfectionism" (Joseph Chan 陳祖為), they have had a profound impact on the discourse of Confucian political theory. Turning toward the [End Page 1] political works of Mou Zongsan and the British idealists, Tseng neither advocates for the inherent elitism and anti-Western sentiments of antiliberal Confucianism, nor does he fully subscribe to the radically iconoclast ideals of the anti-Confucian liberals who had denied all value of tradition and saw Confucianism as a mere obstacle toward a modernized China. Another aspect of Tseng's study that stands out from the current field of research on Mou Zongsan is his reading of Mou's conceptual framework through the lens of Hegel. While many prominent researchers, e.g. Li Minghui 李明輝, point toward Mou's reliance on Kantian ideas and concepts, Tseng convincingly argues that Mou's appropriation of the idealist framework, as well as many concepts utilized by Mou, are fundamentally Hegelian, therefore warranting a shift in perspective. Confucian Liberalism is subdivided into three parts and eight chapters. Part I, titled "Confucian Ethics," introduces the reader to Mou Zongsan's moral philosophy by providing a comparative analysis of Mou, Kant, Hegel, and the British idealists, primarily represented by T.H. Green and F.H. Bradley (1846–1924). In part II, "Civil Liberalism," Tseng then moves on to elaborate on the New Confucian view of politics. Here, he pays close attention to Mou's revaluation of Confucian politics through the Hegelian framework, the notion of "civility," and the concept of "humane government." Turning again to Mou and Green, the final part, "Perfectionist Liberalism," presents the political vision of a democratic state underpinned by a strong belief that the primary task of the state is to provide an environment for the individual citizens that allows them to fully realize their moral capabilities. The third part further argues that the values upheld by New Confucianism not only do not contradict the liberal values of human dignity, tolerance, and equal respect, but are in fact able to lay a moral foundation for modern democracies that is able to overcome the weaknesses of mainstream liberalism, manifested in atomism, nihilism, and egoism. Chapter 1 introduces the reader to the core principles and concepts of Mou Zongsan's moral metaphysics. Following Mou's own approach, Tseng applies a comparative method in this introductory chapter, meticulously delineating the varying philosophical influences that shaped Mou's... (shrink)

The MS. tradition of Prudentius is particularly interesting, since in the famous Codex Puteanus we have a MS. dating from the early sixth century—i.e. but little more than a hundred years after the publication of the collected poems in 405. Yet it has only been of late years that due consideration has been given to this ancient Codex, which is the actual MS. corrected by Vettius Mavortius' own hand. Mr. Winstedt has spoken of the neglect which it has suffered for (...) the most part from editors, and also of the similar lack of attention paid even by Dressel to its seventh-century companion at Milan—the Codex Ambrosianus; while, later, J. Bergman shewed himself enthusiastic in its praise . A confirmation is now available of a curious and generally discredited reading in this MS. , from that same Arma glossary of ‘saec. viii.-ix’ which bears witness to the readings of a lost Terence MS. of the δ-family, the best minuscule family, older than any extant MS., as I shewed in the April, 1925, number of this journal. At Prud. Apoth. 895 the reading of Puteanus is— Agenitus genitusque deus, pater et patre natus. (shrink)

In this paper I shall venture into an area with which I am not very familiar and in which I feel far from confident; namely into phenomenology. My main motive is not to get away from standard, boring, methodological questions like those of induction and demarcation; but the conviction that a phenomenological account of the empirical basis forms a necessary complement to Popper's falsificationism. According to the latter, a scientific theory is a synthetic and universal, hence unverifiable proposition. In fact, (...) in order to be technologically useful, a scientific hypothesis must refer to future states-of-affairs; it ought therefore to remain unverified. But in order to be empirical, a theory must bear some kind of relation to factual statements. According to Popper, such a relation can only be one of potential conflict. Thus a theory T will be termed scientific if and only if T is logically incompatible with a so-called basic statement b, where b is both empirically verifiable and empirically falsifiable. In other words: T is scientific if it entails ¬b; where b, hence also ¬b, is an empirically decidable proposition. (shrink)

Domestic livestock animals and soils must be considered together as part of an agroecosystem which includes plants. Soil sustainability may be simply defined as the maintenance of soil productivity for future generations. There are both positive and negative aspects concerning the role of animals in soil sustainability. In a positive sense, agroecosystems which include ruminant animals often also include hay forage-or pasture-based crops in the humid regions. Such crops stabilize the soil by decreasing erosion, improving soil structure and usually require (...) fewer chemical inputs. Monogastric animal culture is based on an agroecosystem consisting of mainly grain crops. These crops can result in the soil being exposed to water and wind erosion although soil conservation practices that significantly reduce soil losses may be followed. The management of animal manures is not always compatible with soil conservation practices. Careful management of the nutrients in manure is absolutely necessary to avoid nitrate contamination of ground water or phosphorus loading of streams and lakes. In a negative sense, increases in animal livestock populations in association with human population growth are promoting desertification in the arid and semi-arid regions of the world. The key component for a fully compatible and acceptable association between domestic animals and soil productivity is proper management. Careful management of the components of an animal-based agroecosystem is required if soil productivity and environmental quality are to be maintained. Although we have much to learn, technologies are available to move a considerable way towards this ideal state. (shrink)

We discuss a generalization of the standard notion of probability space and show that the emerging framework, to be called operational probability theory, can be considered as underlying quantal theories. The proposed framework makes special reference to the convex structure of states and to a family of observables which is wider than the familiar set of random variables: it appears as an alternative to the known algebraic approach to quantum probability.

We study the possibility of representing the proposition lattice associated with a quantum system by a linear vector space with coefficients from ap-adic field. We find inconsistencies if the lattice is assumed, as usual, to be irreducible, complete, orthocomplemented, atomic, and weakly modular.

The probability pattern emerging in two-slit experiments is a typical quantum feature whose essential ingredients are examined by translating them into the spin- $ \frac{1}{2} $ formalism. In view of the existence of extensions of quantum theory preserving some classical structure, we discuss how the two-slit probabilities behave under such extensions. We consider a generalization of the standard classical probability theory, to be called operational probability theory, that turns out to host the so called quantum probabilities.
