Finance ethics have drawn increasing attention from both government regulators and academic researchers. This paper addresses the issue of insider trading ethics. Previous studies on insider trading ethics have failed to provide convincing arguments and consistent results. In particular, the arguments against insider trading are based primarily on moral and philosophical grounds and lack empirical rigor. This study intends to establish and examine the relationship between the ethical issue and economic issue of insider trading. We argue that the ethics of (...) insider trading is in essence an economic rather than a moral issue. It is so far not clear to what extent insider trading may increase or decrease shareholders wealth. Until then, we must take care to avoid over-regulating insider trading. (shrink)

This paper addresses weighting and partitioning in complex reinforcement learning tasks, with the aim of facilitating learning. The paper presents some ideas regarding weighting of multiple agents and extends them into partitioning an input/state space into multiple regions with di erential weighting in these regions, to exploit di erential characteristics of regions and di erential characteristics of agents to reduce the learning complexity of agents (and their function approximators) and thus to facilitate the learning overall. It analyzes, in reinforcement learning (...) tasks, di erent ways of partitioning a task and using agents selectively based on partitioning. Based on the analysis, some heuristic methods are described and experimentally tested. We nd that some o -line heuristic methods performed the best, signi cantly better than single-agent models.

top-down approach (that is, turning declarative knowledge into procedural knowledge), we adopt a bottom-up approach toward lowlevel skill learning, where procedural knowledge develops rst and declarative knowledge develops from it. Clarionwhich follows this approach is formed by integrating connectionist, reinforcement, and symbolic learning methods to perform on-line learning. We compare the model with human data in a mine eld navigation task. A match between the model and human data is observed in several comparisons.

There has been much research into teacher beliefs about teaching and learning as seen in the general teacher education literature. In the field of language teacher education, this line of research has been evolving, with the recent trend being streamlined into “teacher cognition” as a generic or umbrella term. Despite increasing amounts of research output so far, research into foreign language teachers’ cognitions about their own teaching and decision-making is still insufficient, particularly with regard to university-level English-as-a-foreign-language (EFL) teachers in (...) China. Drawing on Vygotsky’s Sociocultural Theory, this qualitative research focused on EFL teachers’ cognitions about form-focused instruction in Chinese university settings. It intended to discover how teachers’ cognitions changed when they were expected to teach in actual classrooms and what factors contributed to these changes. Data collected from four teacher-participants through semi-structured interviews, classroom observations and follow-up stimulated recall interviews showed participants’ support forfocus-on-forminstruction, which means they not only paid attention to the grammatical form of the language but also to the meaning it is intended to convey. However, data also showed that the teacher-participants shifted fromfocus-on-formtofocus-on-formSinstruction in actual teaching, which suggests that they might have realized the challenges of carrying out teaching activities surroundingfocus-on-formand would like to take an easier approach by only teaching the grammar of the language byfocusing on formS. Such incongruences are interpreted with reference to a plethora of sociocultural factors including traditional Chinese thinking and institutional expectations. The implications of the findings for stakeholders in universities, including faculty members, students, and curriculum developers in similar contexts, are also discussed. (shrink)

BackgroundIt has been well investigated that nature exposure intervention can restore directed attention and improve subsequent cognitive performance. The impairment of decision-making skills in mentally fatigued soccer players was attributed to the inability of attention allocation. However, nature exposure as the potential intervention to counter mental fatigue and improve the subsequent decision-making skill in soccer players has never been investigated.ObjectsThis study aimed to evaluate the effects of nature exposure intervention on decision-making skills among mentally fatigued university soccer players. Moreover, different (...) durations of nature exposure were also evaluated.MethodsA random control between-subject design was adopted. Players were randomly assigned into six groups with three different durations of the experimental group compared with the corresponding control group. All players were first mentally fatigued by performing a 45-min Stroop task; then, they viewed virtual photos of natural or urban scenes; and finally, they performed a soccer decision-making task.ResultsThe subjective ratings of mental fatigue were significantly higher following the Stroop task. Only Exp 3 significantly improved decision-making reaction time compared with Con 3. Moreover, the accuracy slightly increased in Exp 3 after the intervention.ConclusionIn line with attention restoration theory, nature exposure significantly improved decision-making skills in mentally fatigue university players. However, the duration must be 12.50 min for each stimulus to stay longer to attract involuntary attention. (shrink)

We present a skill learning model CLARION. Different from existing models of high-level skill learning that use a topdown approach (that is, turning declarative knowledge into procedural knowledge), we adopt a bottom-up approach toward low-level skill learning, where procedural knowledge develops first and declarative knowledge develops later. CLAR- ION is formed by integrating connectionist, reinforcement, and symbolic learning methods to perform on-line learning. We compare the model with human data in a minefield navigation task. A match between the model and (...) human data is found in several respects. (shrink)

Emojis and stickers are becoming increasingly popular in computer mediated communications. The present study examined the associations between personality traits and people’s reasons and patterns for using both emojis and stickers. Participants (n= 312) completed three on-line questionnaires assessing shyness, the Big Five personality traits and why and how they used emojis and stickers. Results revealed that shyness, neuroticism, extraversion and agreeableness were correlated with different reasons of usage. Moreover, some participants exhibited a tendency to adjust frequency of usage depending (...) on who the target person was and whether they were in a private or group chat. People who showed such tendencies were found to differ in personality with those who did not. Some differences in usage patterns were also observed between emojis and stickers. Together, the present study sheds more insights into how emojis and stickers can help people with different personality traits to achieve different purposes in their daily communication. (shrink)

Effective social data governance rests on a bedrock of social support. Without securing trust from the populace whose information is being collected, analyzed, and deployed, policies on which such data are based will be undermined by a lack of public confidence. The COVID-19 pandemic has accelerated digitalization and datafication by governments for the purposes of contact tracing and epidemiological investigation. However, concerns about surveillance and data privacy have stunted the adoption of such contact-tracing initiatives. This commentary analyzes Singapore's contact-tracing initiative (...) to uncover the reasons for public resistance and efforts by the state to address them. The government's contact-tracing program encompassing its proprietary TraceTogether app and physical token initially triggered vociferous public criticisms of Big Brother style surveillance. Using a dialogic communication framework, we analyze the TraceTogether initiative to interrogate the communicative strategies that were used to overcome public resistance. We argue that these strategies reflect a top-down approach that prioritizes transactional dissemination of information, in line with Singapore's technocratic stance toward governance. We further assert that such communicative tactics represent missed opportunities to foster public confidence in social data governance through greater trust building. We propose solutions for more dialogic communicative forms that build trust, so that officials can develop a sound understanding of the public concerns, increase the level of public engagement, and incorporate public feedback into policies that govern data use.

Dans les théories traditionnelles de la sociologie du développement, les recherches se concentrent sur deux axes. D’un côté, les théories de la modernisation, qui étudient l’évolution des pays développés, de l’autre, celles du développement, qui s’intéressent aux modèles latino-américains, africains et est-asiatiques. Ces deux axes traditionnels limitent fortement le champ de vision de la sociologie du développement. Nous montrerons que les processus de transition dans les pays socialistes tels que la Chine, l’ex-URSS ou l’Europe de l’Est soulèvent toute une série (...) de débats inédits. Comment analyser la voie de développement propre à des régions et des pays différents ? Comment examiner les relations entre l’État et la société au sein du processus de développement et de transition ? Comment aborder le problème des inégalités sociales au sein de ce processus ? Autant de nouvelles questions – et ce ne sont pas les seules – qui élargissent non seulement le champ de vision de la sociologie du développement, mais qui permettent aussi d’envisager une nouvelle théorie pour cette discipline. Il s’agit d’observer le processus pratique de transition sociale dans les pays de l’ancien bloc communiste. L’objectif ? Restructurer la sociologie du développement autour de trois piliers : les théories de la modernisation, du développement et de la transition.Among the traditional theories in the sociology of development, research generally focuses on two lines. On the one hand, the theories of modernization, which mainly study the evolution of developed countries, on the other hand, the theories of development, which are interested in the patterns spread out by Latin America, Africa and East Asia. Those two directions set serious restrictions on the sociology of development’s scope. We’ll show that the transition processes of socialist countries such as China, ex-USSR or Eastern Europe actually raise a whole series of new debates. How should we analyze the specific way of development of countries or areas that are different ? How examine the relations between State and society during the development and transition process ? How should we deal with the issue of social inequalities during this process ? These new interrogations – and many others – do broaden the sociology of development’s horizons, but also help us build up a new theory for the discipline. We must scrutinize the practical process of social transition in the countries which were part of the former communist bloc, and, in so doing, rebuild the sociology of development on three pillars : the theories of modernization, of development and of transition.

Information-sharing behavior is affected by identity recognition perception. The current study aims to delve into the impact of familiarity and anonymity on information-sharing behavior, and the mediating role of intrinsic motivations on WeChat Moments. We hypothesized a mediator role of intrinsic motivations in the relationship between an individual’s perceptions and information sharing. Based on the self-determination theory, a model was created and tested using a sample of 531 frequent users. In this study, these users were asked to use WeChat Moments, (...) the most popular mobile private social networking site in China. The results demonstrate the significance of familiarity and identifiability in an interpersonal relationship, when using social networking sites. Moreover, the influence of perceived anonymity on information-sharing behavior, which is entirely mediated by intrinsic motivation has been validated from an empirical perspective. Our findings extend previous studies by showing the totally mediated effect of perceived anonymity on information-sharing behavior on WeChat Moments and the influential mechanism of intrinsic motivation. The results will inform researchers about the importance of incorporating the interpersonal structural features and intrinsic motivation of social networking sites into future studies on online information-sharing behavior. Important ways to promote attention and share information involve building a familiar relationship with communities and equipping oneself with off-line relations. Final indications for future developments are provided, with a special emphasis on the development of these findings in various social networking sites contexts. (shrink)

Humans can seamlessly infer other people's preferences, based on what they do. Broadly, two types of accounts have been proposed to explain different aspects of this ability. The first account focuses on spatial information: Agents' efficient navigation in space reveals what they like. The second account focuses on statistical information: Uncommon choices reveal stronger preferences. Together, these two lines of research suggest that we have two distinct capacities for inferring preferences. Here we propose that this is not the case, and (...) that spatial-based and statistical-based preference inferences can be explained by the assumption that agents are efficient alone. We show that people's sensitivity to spatial and statistical information when they infer preferences is best predicted by a computational model of the principle of efficiency, and that this model outperforms dual-system models, even when the latter are fit to participant judgments. Our results suggest that, as adults, a unified understanding of agency under the principle of efficiency underlies our ability to infer preferences. (shrink)

Urban space is the spatial projection of various social and economic activities. Given the complexity of urban functions and the ongoing expansion of urban areas, the spatial differentiation of various economic activities within cities tends to become more and more clear; moreover, there tends to be spatial inequalities in resource allocation. Taking Beijing as an example, this study develops a spatial accessibility model at the town level by integrating the spatial distribution of economic activities with the transport system and evaluating (...) the accessibility to various economic activities. The equality of the residents’ economic-related travel activity is also evaluated in line with the population distribution. The results show that the accessibility to economic activities generally decreases in going from the urban center to the peripheral suburbs, and this “core to edge” difference is readily apparent. In general, residents tend to choose areas to settle in which have a high degree of accessibility, however, the attractiveness of accessibility is constrained within certain limits, as evidenced by a reduction of population in the center of Beijing. Additionally, there are inequalities with respect to traveling experiences. For instance, 27.8% of residents experience very convenient travel conditions, mostly in the Xicheng, Dongcheng, and Haidian districts, and this equates to a high level of accessibility; about half of the residents in Beijing live in areas ranked as being of medium accessibility and where the distribution of economic activities and transportation facilities are insufficient. Residents living in the outlying Changping, Mentougou, Shunyi, and Fangshan districts have relatively poor access to transportation indicating a low level of accessibility. Overall, the evaluation method for spatial equality considers comprehensively the distribution of economic activities, transportation, and population distribution and can provide a reference framework for optimization of the urban spatial structure to improve urban spatial equality.

The model is a connectionist one based on a two-level approach proposed (...) earlier. Acknowledgements: This work is supported in part by O ce of Naval Research grant N00014-95-1-0440. (shrink)

Antibiotic resistance in bacteria has become a great threat to global public health. Tigecycline is a next‐generation tetracycline that is the final line of defense against severe infections by pan‐drug‐resistant bacterial pathogens. Unfortunately, this last‐resort antibiotic has been challenged by the recent emergence of the mobile Tet(X) orthologs that can confer high‐level tigecycline resistance. As it is reviewed here, these novel tetracycline destructases represent a growing threat to the next‐generation tetracyclines, and a basic framework for understanding the molecular epidemiology and (...) resistance mechanisms of them is presented. However, further large‐scale epidemiological and functional studies are urgently needed to better understand the prevalence and dissemination of these newly discovered Tet(X) orthologs among Gram‐negative bacteria in both human and veterinary medicine.

I Want in this paper briefly to contribute two points to the elucidation of this famous passage, and apologize for the fact that my possessing the same name as one of its most illustrious interpreters may add confusion to the doxographic tradition. The first point is not an original one. It is simply to revive an interpretation given by Henry Jackson in an article which strikes me as the most profound and pellucid which I have read on the subject, and (...) which is in some danger of being forgotten. Raven, about ten years ago, insisted as a criterion of interpretation that the entire passage should be viewed ‘as a single and indivisible whole’. This is precisely what Jackson does, though he concentrates his attention, as indeed does Raven, on the line and the cave. (shrink)

Background Moral sensitivity and academic integrity discernment hold paramount importance for healthcare professionals. Owing to distinct undergraduate educational backgrounds, nurses and physicians may exhibit divergent moral perspectives, academic integrity cognisance, and moral sensitivity within clinical environments. A limited number of studies have investigated the disparities and congruencies pertaining to moral sensitivity and academic ethical awareness among nursing and medical students. Objective The study compares moral sensitivity and academic ethical awareness of undergraduate nursing and medical students with and without clinical exposure. (...) Research design A self-administered cross-sectional survey conducted from January to February 2022 was used to collect data from a medical school in Hong Kong. Participants and research context A total of 545 respondents, including 137 nursing students and 408 medical students, completed the questionnaire. Ethical consideration Ethics approval of the study was obtained. Written consent was waived to maintain anonymity because completing the questionnaire was considered implied consent. Findings Both groups of undergraduates demonstrated a high level of bioethics knowledge. In terms of academic integrity, medical students were found to have a less concerned attitude towards punctuality, attendance, and skipping classes. Regarding moral sensitivity, senior medical students with clinical experience put less emphasis on decision-making involving patient participation, while senior nursing students were more hesitant in withholding treatment for incompetent patients who refused treatment. Both nursing and medical students showed decreased moral sensitivity in the ‘conflicts’ domain with increased clinical exposure. Conclusion Study findings contribute to the discussion comparing the ethical attitudes of nursing and medical students. More effort should be made in nursing and medical education to promote practices in line with high academic integrity and to develop the ability to be morally sensitive in professional settings.

It may seem strange, in view of the spate of recent literature on the subject, that yet another article should be forthcoming on what is certainly the most familiar, as well as the most vexed, of all Platonic passages. But it is precisely this spate of literature that has impelled me to write. The time seems to have come for an article which, rather than seeking desperately for something new, sets out instead to reaffirm those facts and conclusions that even (...) the most resolutely original of scholars could hardly venture to dispute. This article will therefore be based, not on any of the numerous modern interpretations, but on what Plato himself actually wrote. It will contain a number of tentative suggestions which, to the best of my knowledge, have not been made before. They can, and probably will, be rejected. But its primary purpose remains to restate, whenever possible in Plato's own words, a number of important facts that are at once so simple and so obvious that they seem repeatedly, and especially in recent years, to have been quite forgotten.

No part ot Plato's writings has been more debated than the three similes in Books VI.-VII. of the Republic, and still there is a diversity of opinion about their meaning. I believe that most of these difficulties arise from certain assumptions about their purpose which need revision. The current view applies the Cave to the Line, as Plato seems to direct, and this application, which is itself attended by considerable difficulties, leads to an assimilation of the two figures till they (...) seem to have much the same content and purpose. Again, as this makes the lower line appear to be the phenomenal world, it is thought that the simile of the sun foreshadows the theme of the Line by hinting at a connexion between the intelligible and the sensible which is made more explicit in the Line. Thus the group of similes seem mainly intended to show the dependence of Becoming upon Being. This paper will argue that such a view depends upon the misrepresentation of the symbolism adopted by Plato, that two antithetical groups of symbols are confused with one another, and that symbols are even identified with antitypes. Owing to these misinterpretations the Form of the Good has been mistaken for a material cause; both the Line and the Cave have been thought to reveal Plato as embarrassed by a dualism between sense and intellect, and the purpose of the Cave in particular, since the error is cumulative, has been completely obscured. This paper will attempt to substitute for current accounts another interpretation which will relate the three similes closely with the political arguments of Book VI., and with the Platonic education which is set forth in close connexion with them.

“Walk on the Sun” is an interactive experience of image as music. As explorers move across images that are data projected onto the floor, their movements are visually tracked and used to select pixels in the images which they immediately hear as musical pitches played by various instruments. The sonification design maps color to one of 9 instruments, brightness to one of 50 pitches, and location in the image to panning position, creating 57,600 differentiable musical events. This high resolution and (...) interactive auditory presentation of pixel data enables the blind to explore images of the Sun from the STEREO space mission, nebula and galactic images from Hubble, as well as art masterpieces. Specifically, the blind can hear when hot spots cross the center of the Sun or the solar winds and corona are changing by sonifying virtual geometric structures, such as lines and circles, to create chords of music reflecting the changing content of the selected pixels within that structure as images are played as movies. Originally funded by a NASA/STSCI Ideas grant, the exhibit has toured to more than 12 cities in the US, visiting blind and science centers in the process and receiving enthusiastic response throughout. Plans for additional work furthering NASA wide image sonification standards are in process. (shrink)

At the end of the Sixth Book of the Republic Plato explains the Idea of Good by means of the Figure of the Sun. As the sun is the cause both of the becoming of that which is subject to becoming and of our apprehension of it and of its changes through the eye, so the idea of good is the cause of the being of that which is and also of our knowledge of it. As the sun is beyond (...) γxs22EFνεσις, so the Idea of Good is beyond Being. Glaucon says he does not understand. The simile is further elucidated by means of a line, divided into two parts, of which one stands for the νιητxs22EFν γxs22EFνος τε καxs22EF τxs22EFπος, where the Idea of Good bears rule, the other for the xs22EFρατxs22EFν γxs22EFνος τε καxs22EF τxs22EFπος, over which the sun is lord. The line is to be divided unequally , and subdivided in the same proportions. Thus we get a line consisting of four parts in the ratio 4 : 6 : : 6 : 9. Let us call the four parts A B C D respectively, A being the smallest, D the greatest, B and C necessarily equal. A stands for εxs1F31κxs22EFνες, shadows, images in water and on polished surfaces, and the like: B stands for animals, plants, and the creations of human industry: C for the objects of that enquiry in which the objects denoted by B are treated as images, i.e. mathematical enquiries: D for the objects apprehended by dialectic, the Ideas themselves. The first equation asserted is—The objects of opinion : objects of knowledge : : representation : original . There follows an explanation of the inferiority of mathematical to philosophical reasoning, and an explanation of the statement that the objects denoted by B are used as images or symbols by the enquiry concerned with C; as a result of which Glaucon perceives that the general distinction between C and D is that between the τxs22EFχναι , i.e. those sciences in which the Guardians were to be educated, and Philosophy or Dialectic. Finally a special πxs22EFθημα or affection of the soul is allotted to each of the four divisions of the line, to A εxs1F31κασxs22EFα, to B πxs22EFστις, to C διxs22EFνοια, to D νxs22EFησις, each πxs22EFθημα being clear in the same degree in which the objects it is concerned with are true.

In this essy I shall enter into the vexing question of Plato’s „theory of intermediates“, and the relation of this theory to the Sun, Line and Cave section of Republic VI and VII. My thesis is that in the last 75 years or so scholarly opinion has reached a complete impasse, having veered from one extreme to another, rather than in the fashion of an Hegelian thesis and antithesis; this conflict of opinion desperately requires a sythesizing „third“, and in the (...) conclusion of the paper I try to supply this „third“.

The City of the Sun is Tommaso Campanella's best known work, even though it represents only a small fraction of the vast literary production of a man who claimed to have been called to reform society, religion, and all the sciences and spent many years of his troubled life in writing on the most disparate subjects. The work, as the subtitle indicates, is a poetical dialogue describing an imaginary and hypothetical state ruled by philosophers who have never come into contact (...) with Christian revelation and whose only guide is reason. Written along the lines of Thomas More's Utopia and Plato's Republic, Campanella's fictional dialogue contains the germs of many social, political, and educational reforms that would be beneficial to the state, even though the system of community of goods and women strongly advocated by the rulers of the ideal republic does not seem to do justice to the rights of the individual citizens.

Elaborating the analogy between the sun and the good, Plato's Socrates tells Glaucon to divide a line αβ into two unequal segments at γ. The result is that αγ represents what is intelligible and γβ what is visible.1 Then Glaucon is to divide each of the two segments by the same ratio as he used in the original division.2 Whatever proportion he used to make the cuts γ, δ, and ε in the divided line, generating its four segments, the geometrical (...) implication is that the two middle segments must be equal in length. As both Nicholas D. Smith and Richard Foley have emphasized, when Socrates reiterates the characteristics of the line at 534a3–5, transposing δγ and γε, there should be no doubt that Plato...

In this article I explore a tantalising definition of cinematic belief as a belief without belief by briefly considering the way in which film theory and film-philosophy have engaged with the question of belief in cinema. I also take into account Simon Critchley’s discussion of religious belief in The Faith of the Faithless (2012) within the context of anthropological studies of religion such as that by Émile Durkheim. In addition, I discuss Sigmund Freud’s 1927 reflection on religion in “The Future (...) of an Illusion”. I then show that this line of thought can be linked to the philosophical discussion around the so-called paradox of fiction and introduce the idea that belief can be understood itself as an emotion or mood. I argue in favour of the solution to the paradox that claims that emotions experienced in response to fictional entities are quasi-emotions but radicalise this claim by showing that this must imply that all emotions are in fact structured like quasi-emotions and that we do not require an essentialist understanding of emotion in the first place. Throughout I use the example of the various cinematic representations of the life of St Francis to flesh out the argument, including Roberto Rossellini’s Francesco, giullare di Dio / Francesco, God’s Jester / The Flowers of St Francis (1950) but particularly Franco Zeffirelli’s much maligned Brother Sun, Sister Moon (1972).

The Canticle of the Creatures or Canticle of Brother Sun is based on a particular way of perceiving reality. Francis, who had turned away from ‘the world’, discovered a different way of looking at it. This is a divine way of perceiving, in which the senses do not grasp reality, but accept it as it communicates itself. This way of perceiving is only possible if one does not attempt to master the environment, but allows one’s senses to be weak. It (...) is significant, therefore, that this song of praise was born at a moment of the utmost despair and weakness. The song’s content is in line with this weak perception: it is not about Francis who praises God and His creatures, but rather it is a testimony that the creatures-the elements-are already praising God, and a prayer that He should let Himself be praised by the creatures. Also in line with this weak perception is the fact that the creatures are praised just as they communicate themselves to Francis: as bodies. The theology of this song is that the creatures through their bodies resonate the blessings that come from God, thereby making His blessing present here on earth. Francis’ role is to give a voice and a language to the heavenly praises as they resound in his environment. The transformative power of this song is that we, whether consciously or not, do the same thing when we participate in this song. (shrink)

In this paper, I argue against the claim that in Plato's Republic the most important distinguishing feature between the philosopher and non-philosopher is that the philosopher has knowledge while the non-philosopher has, at best, true opinion. This claim is, in fact, inconsistent with statements Plato makes in later books of the Republic. I submit that the important distinction Plato makes concerns the type of knowledge possessed by the philosopher-ruler. As a result, we need to amend widely held scholarly interpretations of (...) important passages in the Republic ; most notably the passages containing the Sun, Line, and Cave. I consider the views of a number of important scholars and suggest a proposal that avoids this inconsistency with the text. An important consequence of my argument is that Philosophers are indeed not the only ones with knowledge in the Kallipolis. (shrink)

The paper puts forward a new interpretation of the image of the Cave, that is the image on human paideia (education) and apaideusia (lack of education). The cause of the apaideusia (R.514a) is identified as a separation from the origin. (1) First, the relation between the Cave, the analogy of the Linie and the Sun is shown not to be a strict parallelism, but a resemblance, which implies sameness and difference between Sun, Line and Cave. (2) Second, the author argues (...) that the idea of the Good is the necessary condition for the possibility of being, truth and thought. It is the highest principle and the ultimate foundation of Plato’s ethics. (3) Third, the author describes Plato’s paideia (education) as holistic, that is: it involves the spiritive and appetitive part of the soul. (shrink)

The similes of the Sun, Line, and Cave in the Republic remain a reproach to Platonic scholarship because there is no agreement about them, though they are meant to illustrate. I propose to analyse the form of the argument, a clue that has never been properly weighed. The Greek theory and practice of analogia and diairesis give good evidence about the method that Plato adopted; if this usage were respected, the analogical argument would not be so loosely interpreted, and the (...) double diairesis and proportion that the Line actually is could not be mistaken for a classification. I hope also to show that Plato's terminology is definite and consistent; here too ancient usage helps to establish his meaning. (shrink)

‘The similes of the Sun, Line, and Cave in the Republic remain a reproach to Platonic scholarship because there is no agreement about them, though they are meant to illustrate.’ So wrote A.S. Ferguson in 1934, and so he could write to-day. Four decades have produced at least twenty more substantial contributions to the debate, but no agreement. I shall not attempt to arbitrate between existing interpretations, nor shall I offer an account of the ‘simile of light’ as a whole. (...) I shall confine my attention to a single point: the significance of the shadows in the cave, and of the objects which cast them. The suggestion I shall make seems an obvious one, but I have not found it in the literature. I hope to show at least that it deserves serious consideration. (shrink)

It was applied to deal with sequential decision tasks. Experiments and (...) analyses in various ways are reported that shed light on the advantages of the model. (shrink)

SummaryThe discovery of dark lines in the spectrum of the sun as well as in some fixed stars since 1802 by William Hyde Wollaston, Joseph Fraunhofer and Johann Lamont is a relatively isolated phenomenon in the history of astronomy of the first half of the 19th century. Wollaston's representation of the sun's spectrum of 1802 can be seen as a simplification and reduction of the phenomenon by way of a seemingly clear connection with contemporary knowledge. Fraunhofer's famous colour etching of (...) the dark lines, of about 1817, can be regarded as a meticulous and painstaking representation of the known facts, taken to a high aesthetic level.Lamont's spectra of the fixed stars from 1836 are the first sketches of all of these phenomena. He emphasized the ‘oddness’, that is, the chaotic variety of identifiable lines. What was common to all of these representations was the general belief that something new and unimaginable could now be established as a scientific subject. The observations of these lines were coincidental with the thinking in other fields, as for example, in Alexander Humboldt's understanding of nature, in Johann Wolfgang von Goethe's theory of light and his interest in pictorial representations of nature, and in the new concept of landscape of the romantic painters.

“People’s lives are written on the fields of old farms. The rows of the fields are like lines on a page, blank and white in winter, filled in with each year’s story of happiness, disappointment, drought, rain, sun, scarcity, plenty. The chapters accumulate, and people enter and leave the narrative. Only the farm goes on.”—From the Introduction In One Small Farm, Craig Schreiner’s evocative color photographs capture one family as they maintain the rhythms and routines of small farm life near (...) Pine Bluff, Wisconsin. “Milk in the morning and milk at night. Feed the cows and calves. Plant crops. Grind feed. Chop and bale hay. Cut wood. Clean the barn. Spread manure on the fields. Plow snow and split wood in winter. In spring, pick rocks from the fields. Cultivate corn. Pick corn. Harvest oats and barley. Help calves be born. Milk in the morning and milk at night.” There’s much more to life on the farm than just chores, of course, and Schreiner captures the rhythms and richness of everyday life on the farm in all seasons, evoking both the challenges and the joys and providing viewers a window into a world that is quickly fading. In documenting the Lamberty family’s daily work and life, these thoughtful photos explore larger questions concerning the future of small farm agriculture, Wisconsin cultural traditions, and the rural way of life.

In this paper, two Platonic texts are placed side by side – namely, the ascent passage from the Symposium and the Sun, Line and Cave analogies from the Republic – in order to dispel the notion that Plato recommends a highly intellectual pursuit of Ideas. We take here the often-neglected aspect of the cave analogy, which speaks of ethical involvement described in terms of descent, and use this to reinterpret the ladder of love. We find that it is not a (...) matter of renunciation and abstraction, but instead, an increasingly refined pursuit of excellence that has the beloved’s moral education as its impetus and goal.

This piece, included in the drift special issue of continent. , was created as one step in a thread of inquiry. While each of the contributions to drift stand on their own, the project was an attempt to follow a line of theoretical inquiry as it passed through time and the postal service(s) from October 2012 until May 2013. This issue hosts two threads: between space & place and between intention & attention . The editors recommend that to experience the (...) drifiting thought that attention be paid to the contributions as they entered into conversation one after another. This particular piece is from the BETWEEN SPACE & PLACE thread: April Vannini, Those Between the Common * Laura Dean & Jesse McClelland, Ballard: A Portrait of Placemaking * Amara Hark Weber, Crossroad * Isaac Linder & Berit Soli-Holt, The Call of the Wild: Terro(i)r Modulations * Ashley D. Hairston, Momma taught us to keep a clean house * Sean Smith, The Garage (Take One) * * * * Momma taught us to keep a clean house. Dust the wood furniture every two weeks. Clean the bathrooms once a week. Wipe down the baseboards once a season (Those damn baseboards. I still got bruises on my knees from scrubbing those things). Sweep away the cobwebs—and pray that those spiders are either dead or delirious (Livin in the country don’t mean you like bugs, especially the ones with too many legs ). Didn’t matter that the house was full of stuff: Great-Grandma’s heirloom dresser, that weird Mammy salt shaker and matching Uncle Tom pepper grinder (Where the hell did Momma get those P.O.S.’s?), the outdated drapes from Belks, Dad’s favorite wooden TV tray, and that uuuuugly love seat that some crazy uncle thought was a glorious find from the Salvation Army (Momma tried to make it pretty with some pillows, but no amount of love could help that seat). Spring Cleaning meant pullin all that furniture away from the walls and holdin your breath to see what time collected in the crevices. Then you gotta be careful not to breathe out too heavy cause the dust would go flying fore you got a chance to catch it. If you didn’t, you’d quickly find out if you’re allergic to dust. Quarter cup of lemon Lysol in a bucket of steaming water and an old wash rag. Maybe two. A dust towel and citrus-scent Pledge. Me and my brothers would fight over who cleaned what. Somehow the twins always got the easy stuff: vacuuming or moving dirt around with the feather-duster. Finishing in enough time to fly down the street on their bikes with the neighborhood kids. Older sister never got off that easy. Each of my stubby fingers morphed into plump, lemon-fresh golden raisins by the time that whole damn house was done. I would finish just in time to sit with Nadine on the porch, counting the seconds til the sun turned off and the fireflies fluttered on. The craziest thing: despite all that cleaning, the house still smelled like Momma’s cookin. That Old House. Might have been some of Grandma’s and Great-Grandma’s cookin mixed in there too. Pork chops. Ham hock soaked in collards. Pinto beans and mustard greens. Corn bread and my Auntie’s famous macaroni and cheese. Didn’t matter if the oven was cold and the valve of the gas stove had been shut for days. A stranger woulda thought someone’d been slavin away in that kitchen for a week straight. No Sweet Citrus & Zest Fabreze back then. Lysol would mask the odors for a little while. Not long enough to overpower the 50 years of goodness marinated in buttermilk, kneaded with lard, and fried in Crisco that’d been embedded in the wallpaper and window treatments. All that grime—dead skin, hair follicles, Carolina clay, carpet lint, yippee-little-dog fur—was evidence of life. We were a socially-awkward newly-minted teenager, two rowdy twin boys, a multi-tasking mother, and a road-warrior father. Eventually a strangely-feline Yorkie was added to the mix. And don’t forget about the stray distant relative stopping by unannounced. No corner of that damn house was unmarked. Hand-sewn pillows in the living room that we were forbidden to breathe on somehow had tiny burnt orange paw prints on them (sneaky little dog). It drove Momma crazy. And tore up my fingernails. They still won’t grow back right. Wipe all that shit off just for it to build up again. But that house was inherited and fully paid for. No reason to move. I did move. I was ready to move on. Move up. Move out. Over that small town. Into the big city. Here the streets take on the smells of Momma’s house. Plus piss, shit, and unbathed skin. A hot day means everything cooks and stews in its own juices, making the stench 10x more intense. The apartment is another story. 11 floors up. Big, east-facing windows. Great view of the skyline dotted with some green foliage. And the great lake. Immaculate. Odorless. Not even a trace of tobacco from the previous tenant’s bad habits. No lingering scent of lemon Lysol. No street stench seeping through the window panes. No stray cat hairs. Or dog fur. Not a speck of dust. Futon. Throw pillows. Photos. Knickknacks. Bowls of fresh citrus. Cursedly-assembled desk set from IKEA. Yet the void is too big to fill. Too clean. (shrink)

It would be difficult to find a more perceptive description of Western man and the world he now inhabits than that provided by Chantal Delsol in Icarus Fallen: The Search for Meaning in an Uncertain World . With style and lucidity, Delsol likens contemporary Western man to the mythical figure Icarus, fallen back to earth after trying to reach the sun, alive but badly shaken and confused. During the twentieth century, Delsol argues, man flew too closely to the sun of (...) utopian ideology. Having been burned, he is now groping for a way to orient himself. But the ideas he once held so dear--inevitable progress, the possibility of limitless social and self-transformation--are no longer believable, and he has, for the most part, long since rejected the religious tradition that might now have provided an anchor. Delsol's portrait is engrossing. She explains how we have come simultaneously to embrace the "good" but reject the "true"; how we have sacralized rights and democracy; and how we have lost our sense of the tragic and embraced the idea of "zero risk." Already a well-known political thinker in her native France, this is Delsol's first book to appear in English. Icarus Fallen should establish her as one of the most insightful social and cultural writers working on either side of the Atlantic. "This is simply the best book about the problems of modern man since Christopher Lasch's Culture of Narcissism . It is so crammed with truth and insight that, as someone once said of Chesterton, every line deserves a review." -- The American Conservative "An extensive evaluation of the pitfalls of modern times and the strict limits on human virtues, Icarus Fallen , is strongly recommended reading for students of 20th Century Philosophy, Politics, and History." -- Wisconsin Bookwatch.

The first part of this paper argued that the traditional application of the Cave to the Line was not intended by Plato, and led to a misunderstanding of both similes. The Cave, it was said, is attached to the simile of the Sun and the Line by the visible region outside the cave, which is a reintegration of the symbolism of sun, originals and images in the sunlight, and the new system of objects inside the cave is compared and contrasted (...) with the natural objects in the visible outside. As we know that the natural symbolism illustrates the Platonic education, our main task in this paper will be to find the meaning of the cave, untrammelled by the associations of the lower line.

Generating energy by renewable sources like wind, sun or water has led to the emergence of “clean” energy that is generally available at low cost to the environment and is generated from seemingly unbounded resources. Many countries have implemented schemes to support the diffusion of renewable energies. The diffusion of micro-generation technologies like roof-top photovoltaics is one of the success stories within the energy transition and has been significantly driven—at least in countries such as Germany—by households. As these households usually (...) not only generate energy but also consume it they are often called “prosumers.” How does it influence the energy behavior of households if they become prosumers? Are these behavioral changes in line with further goals of the energy transition, e.g., reducing demand? What shapes individual behaviors of prosumers? The paper introduces a conceptual framework based on the existing literature on rebound and spillover effects. It systematizes possible behavioral consequences as well as mechanisms behind them. This framework is then used to code and analyze data from 48 in-depth interviews with prosumer households. These interviews reveal a broad variety of behavioral responses which have their roots in economic conditions and their evaluation by the prosumers, psychological mechanisms like central guiding principles and a clear conscience as well as sociotechnical context and legislative frameworks.

In recent times it has become fashionable to emphasize the role of conceptual change in the history of science. To judge from recent writers, every significant theoretical change in science is first and foremost a revolution in scientific concepts—a conceptual revolution. According to this view, every level of experience is affected by each fundamental theoretical change: physical theory, experimental practice and even perceptual experience. The Aristotelian patrician who watched the sun sink beneath the horizon not only had different beliefs about (...) the phenomenon but actually saw something different from the Newtonian gentleman who saw the horizon rise above his eye-sun line, and the Einsteinian professional who saw the sun's varying geometrical relations to the world light-geodesics on which successive temporal stages of his eye world-line lay. Moreover, such is the completeness of the conceptual-experiential shifts undergone in a fundamental scientific change that it is impossible to meaningfully discuss the one theory within the confines of the other or, indeed, to provide any systematic, cumulative comparison of successive theories.

The neutrino is the massless and electrically neutral weak-interaction partner of the electron, always traveling at the speed of light and rarely interacting with anything. The sun makes lots of neutrinos. About 61,000,000,000 neutrinos per second from the sun pass through each square centimeter of cross section on the surface of the Earth. If your body presents an area to the sun of 10,000 square centimeters, this means that 610 trillion neutrinos are passing right through your body in the second (...) it takes to read this line. But you don't notice this; neutrinos can pass through light years of lead without impediment. They pass through your body and through the Earth as if neither was there. As you might imagine, this makes the detection of neutrinos very difficult ... but not impossible. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:just Men and Just Acts in Plato's Republic JEROME SCHILLER I. Introduction Too MUCHhas already been written about Plato's Republic. But this, strangely enough, is why a little more needs to be written. For the book has been worked over so often that an obvious sign of fatigue has set in: critics are beginning to find such elementary flaws in the Republic that one wonders why he should waste (...) time on such a philosophically embarrassing work at all. It is to counter one of these recent criticisms and thus, hopefully, to help offset the fatigue, that this study is written. It purports not only to show the criticism mistaken, but also to sketch a way of looking at the Republic which should send the reader back for a further look at this incredibly rich work. The richness of the Republic is, indeed, a source of embarrassment for anyone writing on it. For because of its structure it is at least misleading to isolate one topic from the myriad others treated there, and because of its complexity, impossible to document interpretations of more than a few topics. I shall follow the time-honored practices here of merely expressing my bias on some topics (such as my non-political interpretation) and leaving it up to the reader to follow up hints of my interpretations of other topics (such as that of the Sun, Line, and Cave). II. Plato's Alleged Fallacy in the Republic David Sachs and A. W. H. Adkins have recently claimed that Plato commits the fallacy of equivocation in the Republic, not in the course of some minor argument, but in answering what is probably the central problem posed by the work: Why be just?1 Simply put, their objection goes like this: In the first book of the Republic, Socrates attempts to prove to Thrasymachus why justice is preferable to injustice. But even Socrates is dissatisfied with this answer and early in the second book, after a brilliantly fashioned defense of the Thrasymachean position by Glaucon and Adeimantus, the brothers ask for a more convincing demonstration from "You, [who have] passed your entire life in the consideration of this very matter." e Socrates seems to accept the challenge and proceeds to a search for the concept of justice writ large in the state. Now, claim Adkins and Sachs, Plato never does answer Glaucon's and AdeiDavid Sachs, A Fallacy in Plato s Republic, Philosophical Review, LX(XII (1963),141158 ;A. W. H. Adkins, Merit and Responsibility, A Study in Greek Values (Oxford,1960),p. 289. Adkins,in developingapolitical interpretation ofthe Republic, doesnot elaborate the criticism as does Sachs; hence I refer in this study primarily to the latter's article. sPlato, Republic 376e 2-3,trans. P. Shorey (2 vols.; Cambridge, Mass.: Loeb Classical Library, 1937-42).All subsequent quotations are from this translation. [1] HISTORY OF PHILOSOPHY mantus' request. For though he does eventually purport to show that justice is preferable to injustice, the justice he attempts to prove this of is not at all the same justice that Glaucon and Adeimantus have in mind. Plato has simply equivocated on the term "iustice," meaning at one time the set of acts generally considered just,s but at another time a certain order in the individual's soul. He has purported to show that an individual with a well-ordered soul reaps advantages, but unless he can show a clear relation between this "Platonic" notion of justice and the "vulgar" notion of justice, the notion which Cephalus, Polemarchus, Thrasymachus, Glaucon and Adeimantus have in mind, he will not have answered the brothers' question, and will thus have avoided the central problem of the Republic. The relation he has to establish is, Sachs claims, that Platonic justice is a necessary and a sufficient condition for vulgar justice. Then he could argue that since he has shown that a man reaps advantages just to the extent that he is Platonically just, (1) a vulgarly unjust individual will not reap more advantages than a vulgarly just one (on the grounds that Platonic justice entails vulgar justice), and (2) a vulgarly just man will reap more advantages than a vulgarly...

And arching over it all, is the logos of The Dreaming. How shall we state this when we fully understand it I do not know, but I should think we are more likely to ennoble it than not. Equilibrium ennobled is abidingness.” 1 On return to birthplace I write. Caught between jetlag and surprise, a relentless sun cracks my skin. Upright words fall under cockatoo roars. The attempt to settle, to be attentive, is shaken. Some kind of Dreaming surrounds and elements intrude without consent. Homeless at home. Exhausted, I fight sleep’s hard currents. Their victory would confuse the body clock, so the in-between wins. Half-there — half-awake — here in this place — I am driftwood. Driftwood: wood floating in or washed ashore by a body of water. A severed limb set adrift from the birthing body. Tossed from home it’s cast into processes of wind, water, sand, bacteria, decay and movement. Driftwood is orphaned members at the mercy and agency of weather, currents, submersion, and being thrown into dry world. Driftwood — singular plural. White man got no dreaming. Him go ‘nother way. White man, him go different Him got road belong himself. 2 photo: Bronwyn Lay The old man comes from the northern rivers. A while ago, he could no longer pay attention to wage slavery, so retreated north to be with dead redgum that lay abandoned in dry riverbeds. Derived from driftwood peoples tossed here by the sea, he followed the fragile river veins of his birth. He walked along water bodies and through country’s lungs. Some kind of displaced ancestral song compelled his leathered hands to pick up centuries old driftwood from flood plains. It emerged from under muddy creeks, was flung up by salt soaked coves, pushed underground by cracks in the claypan and lay embedded in mud and salinized soil. Smoothed and grooved in equal measure, the branches were marked by an organic alphabet that preceded him. As he held the wood, he touched decomposing circles that started with a blast and never ceased writing into abandoned flesh. When the ute was full the old man returned home having been away with the stuff that ‘growed him up’. His shed filled with red sawdust and the sound of tools at labour. His hands sculptured driftwood. History carved into itinerant skin. I sit opposite the old man. His body no longer holds the repetition of carpentry. He can no longer gift driftwood its detail. Outside redgum bits lie scattered around the fence line and beside the dam. He crouches over an unreliable computer researching the massacres of indigenous peoples that occurred along the same river veins that ‘growed him up’ long ago. Staring into the remnants of frontier resistance that he and I inherit, his eyes nurture fire. He discovers severed limbs and the slicing of tribes. In the ashes of sentences he sifts the lies that smoulder into our histories. In the 30’s the anthropologist Stanner said that due to certain factors — lack of change and isolation — the ideal and real come very close together in indigenous Dreaming. They are a people who were able to defeat history. 3 “If the Ideal and the Real drift too far away from one another (as they did at the end of the middle ages and seem increasingly to do this century) men face some difficult options. They have to change their way of life, or their philosophy, or both, or live unhappily somewhere in-between.” 4 Stanner says Indigenous Dreaming is blackfella thinking. 5 Dreamtime is not ethereal, not utopic, or otherworldly. It’s fused with the real and it’s not mine. I might never understand, but it’s the substance of my home. This here place ‘growed me up’. Is driftwood the unhappy in-between? Is it a radical itinerant written upon by currents? Where are we? The settler restless? photo: Alison Pouliot I return to the bush late one night, tired from high talk in city cafes, to find the old man at his computer. He’s either researching his white farming ancestors, or tracing unrecorded massacres of blackfellas. I laugh, “You know Dad, if you were indigenous you might go out by the dam and sing up your ancestors rather than try find them on a screen.” He peers over his glasses. His stare delivers an ancestral scold. He’s white man. Of course he archives. This is our way. One may see that, like all men, he is a metaphysician in being able to transcend himself. With the metaphysician goes a mood and spirit, which I can only call a mood or spirit of assent, neither despair nor resignation, optimism not pessimism, quietism nor indifference. The mood, and the outlook beneath it, make him hopelessly out of place in a world in which the renaissance has triumphed only to be perverted, and in which the products of secular humanism, rationalism and science challenge their own hopes, indeed their beginnings.” 6 The clinamen sometimes comes abstract — the rarefied swerve of possibility. But in the place we gather &mdash where this text has landed — in the heart of settler colony denial — the clinamen reminds of familiar violence and goes maximum. The earth’s swerve. Topography’s tip. Physics gone violent. Here, drift is initiated by the tear of flesh, scurvy voyages, frontier blood and the deracination from belonging. Here, war precedes drift. We all got tossed. Here. Pay attention. The country has its own gaze. ‘Lest we forget’. The seasonal turn on aborescent substances starts with a fall, an upwards rupture, a drop, a cut, a storm, a violence, a loss, forced migration, refugees, agricultural imperialism, settler wheat and poisoned rations. Pay attention to aftermath debris. Don’t drift too far from the real. History hasn’t settled into the water. It still tosses limbs back and forth. Surrounded by the backdrop of Dreaming country the old man archives and dreams. Both ways of settling into the real. But lest we forget, time, in this place, has no textual tick — tock. Our bodies know this, even though we persist with shipwreck illusions. It’s difficult being here. Here. Pay inattention. I walk through eucalyptus, over dried out clay pans and under kookaburras. It’s been two years in-between. This time country speaks strong underfoot. Forget books, forget texts, forget other lands and times, beginning and end. Be here. All falls raw. Leaves drop and refuse to compost. Bark untethers quick. Light denudes worlds. The heated horizon melts monoliths. It’s enough to make Cartesians shiver. Awake. Refuse the temptation to run. Have enough courage to drift into here. Love with a gum tree. Stand with her whole and dissolving. She moves light between our limbs, tossing them to wind. She — the original romance — is the dream that dares touch flesh and reaches over nightmares with elemental desire. I gaze and lose me. There’s no distance. The land that ‘growed me up’ speaks with symbiotic breath. There’s no division, no separation, no other. The gum is plastic arborescence. You be my body for me, always were. …..but I wake to driftwood histories and recall slaughters. Drifted, wicked fellow citizen — the other is someone else’s blind sleep. Betrayal maintains the other as mine. Archives reveal this place doesn’t belong to me. Body articulates that it became here. Gumtree cares not………her arms take me in anyway. “Like all men he is a philosopher in being able to use his power of abstract reason. His genius, his metier, and in some sense — his fate is that because of endowment and circumstance this power has channelled itself mainly into one activity, making sense out of social relations among men living together.” 7 The old man excavates seven generations of settler ancestors. They’re an ordinary lot with written-upon skin. He records genocides that occurred alongside his peoples fertility. Bodies rise from riverbeds like sovereign sacrifices. It hurts. It disrupts. He labours at the past with gestures that might go unnoticed in a country suffocated by rich amnesia. Inside walls, he seems attentive to historical details. Outside he seems inattentive to time, lost to us and embedded in a family of active matter — the bush. His driftwood skin appears around my eyes - grooves of experience, the rush of cruel sun, the push of blind winds, and the love of everything. The sovereign’s reluctant children are thrown here by, with and through blood, but country gets in and sculpts us here. photo: Chris Corrigan “But his abstractions do not put him at war with himself.” 8 The kangaroo family appears at dusk. When the sun is soft I follow the old man into the back paddock. Children skip behind us. In-between generations, I step into the old man’s driftwood leanings. My feet find traces of his understanding – the archivist that reads trees. Here, on home dirt, inattention and attention collapse as we wander into where we are. The roo family gaze at us. Through the grass the old man’s wooden finger articulates kin’s details. He points to the head male, the mother holding a joey in pouch and the young warriors side by side. My children, quieter than ever, meet the laser - eyed silence of another family. In half-light Dad, me, and the kids mirror the kangaroo constellation and stand gentle together. At the bushblock’s limit we encounter ancestral desires. White peoples are subject to driftwood histories. We’re severed limbs attempting to fuse here now, with what was, only to discover our skin becomes racked and embedded with the weather. Into the shelter and fissures of this difficult and ambiguous inheritance, I fall into dream light until balance saturates. Light breaks when the kangaroos move. They bounce someplace else without effort or impact. We turn and tread through the dark towards home. It’s time to sleep. Driftwood skin covers the country. Dreaming is still. photo: Bronwyn Lay NOTES W.E.H. Stanner, The Dreaming and Other Essays , (Melbourne: Black Inc. Agenda, 2009), 72. Ibid., 56.

Available from UMI in association with The British Library. ;Plato's philosophy of mathematics must be a philosophy of 4th century B.C. Greek mathematics, and cannot be understood if one is not aware that the notions involved in this mathematics differ radically from our own notions; particularly, the notion of arithmos is quite different from our notion of number. The development of the post-Renaissance notion of number brought with it a different conception of what mathematics is, and we must be able (...) to see the differences before we can begin to appreciate Plato's views, which must never be seen as applying to a revolutionary notion of mathematics . For this reason the first part of this dissertation must comprise a detailed analysis of these differences, along with some criticisms of those of Plato's modern interpreters who have not taken this point. Much of what will be found here can be found in Jacob Klein's Greek Mathematics and the Origin of Algebra, which will be extensively quoted and interpreted. This book is often quoted, but very seldom understood; or at least, those lessons which should be taken from it are rarely applied to Platonic exegesis. In the second part I attempt a better explanation of Plato's mathematical ontology, beginning with the most extensive passage in the dialogues, the triple image of Sun, Line and Cave in Republic. This reveals a relation between sensibles and forms which is at odds with the traditional view that mathematical objects are never precisely accurate instances of their forms--but this view can be refuted. Plato's view of the nature of mathematical objects will be seen to be a metaphorical way of saying what Aristotle says logically, and is entirely appropriate to the aims and methods of his contemporary mathematicians. Aristotle's criticism of Plato's views is examined and found to make sense and to be appropriate to views which Plato could consistently have held. (shrink)

Where are we to look for the unique hues? Out in the world? In the eye? In more central processing? 1. There are difficulties looking for the structure of the unique hues in simple combinations of cone-response functions like ( L − M ) and ( S − ( L + M )): such functions may fit pretty well the early physiological processing, but they don’t correspond to the structure of unique hues. It may seem more promising to look to, (...) e.g., Hurvich & Jameson’s ‘chromatic response functions’; but these report on psychophysical behaviour, not on underlying physiology. So ‘opponent processing’ isn’t any particular help on the unique hues—and even physiology in general seems not to have come up with any good correlate or explanation. 2. Wright ( Review of Philosophy and Psychology 2: 1–17, 2011 ) looks in a different place: to (a) magnitude of total visual response that a stimulus light provokes, the maxima and minima of which, he thinks, give us the boundaries of the main hue categories (Wright connects these with Thornton’s ‘prime’ and ‘antiprime’ colours in an illuminant: Journal of the Optical Society of America 61 ( 1971 ): 1155–1163); and (b) the ratio of chromatic to achromatic response, the maxima and minima of which, he suggests, give us the focal points of the unique hues. The suggestions are extremely interesting; but the desired correspondences have some counterexamples; and where they hold, one could wonder how much they depend upon the particular choice of functions to measure (a) and (b); and one could hope for more of an explanatory linkage between the sets of items in question. 3. Could the unique hues come from, so to speak, the external world? White and black can easily be defined as particular kinds of reflectance. What of the standard four unique hues? Variation in kinds of sunlight and skylight coincides well with variation along a line from unique yellow to unique blue (cf. Shepard 1992 , Mollon 2006 ). If we wanted something to calibrate our standards for unique yellow and blue as the lens of the eye changes with age, and despite interpersonal cone differences, this would be a good basis—and there are several ways this can be extended to surface colours. But is there any essential connection between these things: is there any rationale why the light of the sun and the sky should be counted as unique hued ? An answer may be: because in our environment, these illuminants are as close to white (or the natural illuminant colour) as you can get—to see things tinged with sunlight or skylight should be to see them minimally tinged with any alien colour. Whereas other hues in an illuminant would be treated as tinging with a more alien colour the thing seen. (shrink)

The approach I propose here to Books VI and VII of Plato’s Republic is to offer some reflections on the organicist and perspectivist readings. Perspectivism seems in some respects to be a variant of organicism. Indeed, both approaches allow for a reassessment not only of the various parts that make up a dialogue, but also, more generally, of the importance of the literary or dramatic form, which is marginalised by the evolutionist reading. The aim of this essay is therefore to (...) try to understand some of the images present in the central books of the Republic, without burdening them with theoretical structures and questionable chronologies, but rather by noting their importance in the overall design of the individual text and their consistence within a broader organism, the entire and unitary Platonic corpus of dialogues. To this end, I will try to highlight the subtle differences between organicism and perspectivism. I will focus on the relationship between literary constructions and theoretical speculations that make the Republic an organically unified text in itself and perfectly consistent with the entire corpus of dialogues. Three images in particular will help me to show how literature and philosophy meet: the sun analogy, the divided line and the allegory of the cave. My aim is not to say what exactly the epistemology of the central books of the Republic consists in, but rather to try to identify the pitfalls in the text when philosophical questions about epistemological issues are separated from literary ones.

In lieu of an abstract, here is a brief excerpt of the content:Christian Humanism in the Age of Critical Philology:Ralph Häfner's Gods in ExileMartin MulsowHäfner's book is a monumental study and a milestone of German-language research.1 He delineates, for the first time, a comprehensive picture of the Christian humanism of European philologists in the era of criticism. Recovering an immense wealth of forgotten sources, the book reveals the complex interaction and tension between pagan mythology and Christian culture in philological controversies. (...) Though authors might denounce the pagan histories of gods as fabulae, they were constitutive for the productive and emulative reception of ancient Greco-Roman patterns in Renaissance and Baroque culture. How could the peculiar logic of this paganizing be handled? Was it advisable to have faith in the integrative power of Christian truth, which was capable of finding precursors or even proofs of one's own truth in pagan patterns, or should the pagan be selectively separated from the Christian? And what was the role of philology in this process? Did the growing expertise in criticism advance the process of dissociation of paganism and Christianity? Did it further new possibilities of synthesis in the spirit of Apologetics? [End Page 659]The reconstruction of these processes involves much more than what the book's very specific title suggests. It is a large-scale history of scholarship written from the perspective of the most important tensions that Christian humanism had to overcome in its final stage. From an Anglo-American perspective, this book contributes to recent reconstructions of ideas of early modern men of learning, as well as the growing number of studies on antiquarianism and the history of religion.2 The final stage of Christian humanism, the period of time covered by the book, begins in the late sixteenth century and ends in the 1730s, a point in time which Häfner presents, with some justification, as the end of an era.Hymnology and PolymathyThe study consists of three basic parts. The first one is the "Persistence of Orphic-Platonic Hymnology in Christian Humanism" ("Fortleben der orphisch-platonischen Hymnologie im christlichen Humanismus"). This topic, apparently very specialized and marginal, proves to be a key arena of early modern scholarship, an arena traversed by the battle lines between pagan tradition and Christianity as well as between poetry and theology. Were hymns inspired poetry? What kind of inspiration could and should be conceded to hymns to Jupiter and the sun? Of course, those humanists who reappropriated Orphism and Neo-Platonism were interested in this genre. In the fifteenth and early sixteenth centuries, and even into the mid-sixteenth century, this was not yet a problem. However, the more philological consciousness (and confessionalization) evolved, the more the genre's scope was delimited. What scope remained? Häfner relates the problem to the revival of an "eclectic Platonism" in the wake of the Second Sophistic. This "eclectic Platonism," which was particularly influential from 1500 on, combined Platonism with rhetorics, and the claim of comprehensive polymathy with the joyful presentation of the findings of reading. In this respect, Apuleius and Aulus Gellius were two model authors for early modern polyhistors. We must include Martianus Capella as a continuation of the "Renaissance of the Second Sophistic into Early Christian Encyclopedism" [End Page 660] ("Renaissance der Zweiten Sophistik bis in die frühchristliche Enzyklopädie hinein," p. 18).Häfner's approach is starkly original and, in my opinion, highly productive for the current debates about early modern encyclopedism and "cultures of knowledge" that are sometimes deadlocked.3 Too frequently, polymathy is used synonymously for encyclopedism, which is often associated with modern concepts of systematic classification. Yet, according to Häfner, this is a misunderstanding. It neglects the playful elements and skillful rhetorical options of throwing questions out into the open rather than narrowing them dogmatically. Perhaps the only addition to Häfner's sources could have been Louis de Cressolles's Theatrum veterum Rhetorum, which, according to Marc Fumaroli in L'age de l'éloquence, marked the return of the Second Sophistic.4 The analysis of the work of Gerhard Johannes Vossius, a classical philologist who resided in Leyden and Amsterdam, is the first test for Häfner...
