La autora presenta una critica a la concepcion clasica de los sentidos asumida por la mayoria de autores naturalistas que pretenden explicar el contenido mental. Esta crítica se basa en datos neurobiologicos sobre los sentidos que apuntan a que estos no parecen describir caracteristicas objetivas del mundo, sino que actuan de forma ʼnarcisita', es decir, representan informacion en funcion de los intereses concretos del organismo.El articulo se encuentra también en: Bechtel, et al., Philosophy and the Neuroscience.

A common view in both philosophy and the vision sciences is that, in human vision, wavelength information is primarily ‘for’ colouring: for seeing surfaces and various media as having colours. In this article we examine this assumption of ‘colour-for-colouring’. To motivate the need for an alternative theory, we begin with three major puzzles from neurophysiology, puzzles that are not explained by the standard theory. We then ask about the role of wavelength information in vision writ large. How might wavelength information (...) be used by any monochromat or dichromat and, finally, by a trichromatic primate with object vision? We suggest that there is no single ‘advantage’ to trichromaticity but a multiplicity, only one of which is the ability to see surfaces and so on as having categorical colours. Instead, the human trichromatic retina exemplifies a scheme for a general encoding of wavelength information given the constraints imposed by high spatial resolution object vision. Chromatic vision, like its partner, luminance vision, is primarily for seeing. Viewed this way, the ‘puzzles’ presented at the outset make perfect sense. 1 Reframing the Problem1.1 Introduction1.2 Three puzzles1.2.1 Why is trichromatic vision an anomaly in diurnal mammals?1.2.2 Why does the colour system occupy such a large and central part in human vision?1.2.3 Why are the blue cones so rare?1.3 Recasting the question2 The Costs and Benefits of Spectral Vision2.1 Spectral information and object vision2.2 Encoding the spectral dimension of light2.2.1 ‘General’ versus ‘specific’ encoding2.2.2 Spectral encoding and the monochromat2.2.3 Spectral encoding and the dichromat2.2.4 Spectral encoding and the human trichromat2.3 Three puzzles revisited2.3.1 Why is trichromatic vision an anomaly in diurnal mammals?2.3.2 Why does the colour system occupy such a large and central part in human vision?2.3.3 Why are the blue cones so rare3 Conclusion.

In Consciousness Explained, Daniel Dennett presents the Multiple Drafts Theory of consciousness, a very brief, largely empirical theory of brain function. From these premises, he draws a number of quite radical conclusions—for example, the conclusion that conscious events have no determinate time of occurrence. The problem, as many readers have pointed out, is that there is little discernible route from the empirical premises to the philosophical conclusions. In this article, I try to reconstruct Dennett's argument, providing both the philosophical views (...) behind the empirical premises, and the hidden empirical arguments behind the derivation of the philosophical conclusions.

For over two centuries, Western scholars have discussed African philosophy and culture, often in disparaging, condescending terms, and always from an alien European perspective. Many Africans now share this perspective, having been trained in the western, empirical tradition. Makinde argues that, particularly in view of the costs and failings of western style culture, Africans must now mold their own modern culture by blending useful western practices with valuable indigenous African elements. Specifically, Makinde demonstrates the potential for the development of African (...) philosophy and even African traditional medicine. Following the lead of a number of countries with government policies of incorporating indigenous medicine with orthodox Western medicine, Makinde argues that traditional African practices should be taken seriously, both medically and scientifically. Further, he charges African scholars with the responsibility of investigating these and other elements of traditional African culture in order to dispel their mystery and secrecy through modern research and useful publications.

The twentieth century in Africa, more than elsewhere in the world, has been an era of startling and unprecedented changes. These changes have been most dramatic with respect to the sociopolitical organization of the continent. While at the beginning of the century, most of Africa, particularly sub-Saharan Africa, had hardly emerged from prefeudal or feudal social formations, the advent of European colonialists, whose avarice for conquest and colonial territories was fueled by the blossoming technological capabilities of the Industrial Revolution and (...) the expansionist market demand of a new and burgeoning capitalist economy in Europe, transformed the face of Africa forever.

Studies on participation and spatial orientations of college students have examined aspects of university life, as projected through language, from a reportorial or narrative perspective, but hardly any one of these studies has been devoted exclusively to how students' participation structure, together with the activities participants orient to at the participation space, evokes shared socio-academic backgrounds and cultural constraints, a major way to gain access into the students' cognitive and pragmatic tendencies. This research, thus, addresses itself to Nigerian college students' (...) participation configuration, their participant roles, and the illocutionary goals of their encounters within the Goffmanian participation framework and discourse pragmatic parameters. For data, 100 interactions amongst students of the Faculty of Arts, University of Ibadan, Nigeria, were taped and scrutinised for participation forms and spatial descriptions. Two types of participation structure are manifest in the interactions, namely, unmarked and marked participations. The unmarked participation structure is the regular frame in which Goffman's ratification and non-ratification framework is strictly observed. The marked participation configuration, an unexpected interactional frame which bifurcates into accommodated and non-accommodated structures, takes interruptions by unaccredited participants as appropriate or inappropriate. The paper contends that participation configuration and contextual elements prescribe participant roles together with the pragmatic functions assigned to language and actions in the interactions. Thus, the illocutionary goals of participants, rooted in socio-academic matters and enabled by participation structures, spatial orientations and body language manipulations are contextually negotiated.

Nigerian Pidgin is a popular informal communicative code in Nigerian social, economic and political experience. It is sometimes spoken in formal situations in the hospital setting when participants find it pragmatically convenient. Despite its communicative significance, little research has been carried out on the use of Pidgin in conversational interactions in Nigerian hospitals, a gap this study fills by investigating how Pidgin is used in constructing emotions relating to social and medical conditions in hospitals. Seventy five interactions between doctors and (...) clients in Nigerian Pidgin were sampled; the data analysis was based centrally on relevance theory. Nigerian Pidgin evokes negative and positive emotions. Negative emotions manifest as pain and fear, while positive emotions appear as excitement and relief. Doctors and clients gain access to each other’s intentions through their shared knowledge of Pidgin, their co-construction of ailments, and their contextually based local interactional resources. They thus negotiate emotions as cue-dependent variables that are steered with the help of cognitive processes. (shrink)

Explains how each director of Central Intelligence sought to fulfill his "community" role, that of enhancing the cooperation among the many parts of the nation’s intelligence community under his leadership. Explores that the nation’s leaders expected of directors and how those holding the responsibility attempted to carry it out.

In this paper, I defend divine conceptualism against one prominent critique from William Lane Craig in his book God and Abstract Objects. Craig argues that the divine conceptualist’s only way out of the “bootstrapping objection” results in an unpalatable concession of defeat to the metaphysical anti-realist. Craig’s argument depends on an analysis whereby God is causally or logically prior to the divine concepts. As such, the conceptualist may resist it by adopting—following Ralph Cudworth—a version of divine conceptualism which does not (...) construe the relationship between God and His thoughts as one of either causal or logical priority.

Abū Ḥanīfa (d. 150/767) discussed the main issues of the science of kalām in the first period and expressed his best views on these issues in response to the sects that he accepted as bid'ah (innovation). Later, kalām scholars tried to justify these views by using different arguments according to the changing conditions and time. Undoubtedly, one of the most important opinions that Abū Ḥanīfa expressed and passed on to the next generations from the perspective of the science of kalām (...) is those related to faith. In fact, faith is the strongest and most deep-rooted bond a believer establishes with his/her Creator. The individual shapes his world and the hereafter through this bond. On the other hand, faith is a phenomenon that does not contain doubt but carries certainty. In this respect, a person is included in the same category as a believer after she has firmly believed, and is called a believer or a Muslim, as the Qur'an puts it. Because no matter what race or color he is, he takes the same name because he believes in the same principles. Abū Ḥanīfa, who lived in a time when Muslims differed among themselves and differences of opinion increased, accepted faith as a common denominator by emphasizing the common values of Islam. Abū Ḥanīfa refers to this as "equality in faith". The issue of equality in faith, which is discussed as a result of the differentiation in matters related to the nature of faith, is shaped according to whether the action is counted as part of faith or not. Since Abū Ḥanīfa did not consider deeds a part of faith, so he advocated equality in faith. This view was adopted later by many scholars in the Māturīdī tradition. In the Hanafī-Māturīdī tradition, it can be said that the issue of equality in faith as well as issues such as confirmation and certainty in faith were shaped by the opinions of Abū Ḥanīfa. When equality in faith is accepted, one is not allowed to question the faith of another and say that his/her own faith is superior to the other because only God can know it. On the other hand, the understanding of equality in faith prevents external appearance and formalism from being decisive in one's religious life. Thus, a believer cannot accuse his brother who has deficiencies in his deeds but has faith of being infidel. When Abū Ḥanīfa's view of equality in faith is interpreted according to contemporary paradigms, his emphasis on human love, tolerance, and unity of the ummah, which has validity today, can clearly be observed. Therefore, it is seen that the reflection of a theological issue on social life is stressed in his opinion. This paper aims to study the issue of "equality in faith", one of the issues related to faith, and its reflection on social life by using the texts which are attributed to Abū Ḥanīfa. (shrink)

This paper theoretically and experimentally investigates the behavior of asymmetric players in guessing games. The asymmetry is created by introducing r>1\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$r>1$$\end{document} replicas of one of the players. Two-player and restricted N-player cases are examined in detail. Based on the model parameters, the equilibrium is either unique in which all players choose zero or mixed in which the weak player (r=1\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$r=1$$\end{document}) imitates the strong (...) player (r>1\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$r>1$$\end{document}). A series of experiments involving two and three-player repeated guessing games with unique equilibrium is conducted. We find that equilibrium behavior is observed less frequently and overall choices are farther from the equilibrium in two-player asymmetric games in contrast to symmetric games, but this is not the case in three-player games. Convergence towards equilibrium exists in all cases but asymmetry slows down the speed of convergence to the equilibrium in two, but not in three-player games. Furthermore, the strong players have a slight earning advantage over the weak players, and asymmetry increases the discrepancy in choices (defined as the squared distance of choices from the winning number) in both games.

Rönesans ve ardında Aydınlanma dönemiyle beraber gerçekleşen bilimsel ilerlemeler fazlaca dikkat çekmeyi başarmıştır. Bunun sonucunda modern bilim, bilginin en güvenilir kaynağı olarak kabul edilerek onun her meseleyi çözebileceği bir zemine oturtturulmuştur. Öyle ki bilim, Tanrı’nın var olup olmadığına dair de bilgi üretebileceği dillendirilmiştir. Bu aşamada ideolojik yaklaşımların ve din adına sergilenen bazı temelsiz akıl dışı argümanların katkısıyla da bilim artık kutsal bir müesseseye dönüştürülmüştür. Kutsala dönüştürülen bilim, bir diğer kutsal olan dinle artık ortak bir zeminde buluşamayacak hale dönüşmüş ve yanlış (...) bir dikotomiye alet edilmiştir. Dolayısıyla artık ilerleyen bilim, yavaş yavaş “Tanrı’yı yok etmeye” başlamıştır. Artık bu hale dönüşen bilim anlayışı ateistlerin de en büyük destek noktaları olmuştur. Kutsala dönüşen bu bilim anlayışı her ne kadar temelde Hıristiyanlık inancına karşıt olarak ortaya çıkmış olsa da yer yer tüm inançlara yansıtılmaya çalışılmıştır. Oysaki bilimden, “bilimin ilerlemesiyle Tanrı’nın yok olacağına” dair veri sunmasını beklemek aslında bilimin sınırlarından bihaber olmayı gerekli kılmaktadır. Bilimin ilerlemesiyle inancın yok olacağı söylemi, İslam dini açısından kabul edilebilir bir argüman olarak görülmemektedir. Çünkü İslam, aklı dinamik olarak tasvir etmekte ve tabiatı Tanrı’nın varlığının delili olarak sunmaktadır. Diğer taraftan bilimin ilerlemesiyle Tanrı’ya yer kalmayacağını iddia edenlerin unutmaması gereken önemli husus, dinin/imanın bir bilgi eksikliği olmadığı aksine bilginin insanı tasdiğe yönelttiği gerçeğidir. Ayrıca Müslümanların bilimde geri kalmalarının sebebini onların inançlarına bağlayanlar, bunu siyasi, sosyal ve ekonomik bazı sebeplerde araması gerekmektedir. (shrink)

Nativists about syntactic processing have argued that linguisticprocessing, understood as the implementation of a rule-basedcomputational architecture, is spared in Williams syndrome, (WMS)subjects – and hence that it provides evidence for a geneticallyspecified language module. This argument is bolstered by treatingSpecific Language Impairments (SLI) and WMS as a developmental doubledissociation which identifies a syntax module. Neuroconstructivists haveargued that the cognitive deficits of a developmental disorder cannot beadequately distinguished using the standard gross behavioural tests ofneuropsychology and that the linguistic abilities of the (...) WMS subject canbe equally well explained by a constructivist strategy of neurallearning in the individual, with linguisitic functions implemented in anassociationist architecture. The neuroconstructivist interpretation ofWMS undermines the hypothesis of a double dissociation between SLI andWMS, leaving unresolved the question of nativism about syntax. Theapparent linguistic virtuosity of WMS subjects is an artefact ofenhanced phonological processing, a fact which is easier to demonstratevia the associationist computational model embraced byneuroconstructivism.

In this study, teleological judgments were examined as having a part of the boundless relationship of reason with the universal and unconditional, based on Kant's critical philosophy. To do this, firstly, the distinction between telos and skopos has been pointed out. The cognitive faculties of the subject as the source of finality in nature and the concepts of purposeless purposefulness were discussed. We emphasized that according to Kant's critical philosophy, the introduction of the concept of God as an internal principle (...) to natural science would be characterized as false belief. This trespassing, which causes a narrative that goes beyond the limits of our knowledge, was discussed in the context of the processes of acquiring knowledge in Kant's philosophy. In this regard, according to Kant the nature of the transition from teleological judgments to theological judgments was investigated. At the beginning of the study, the relation of telos with infinity was discussed. Afterward, the idea of purposefulness, which organizes itself in nature and eliminates blind randomness, was emphasized. The basis of the teleological principle as the inner principle of natural science was analyzed. The possibility of placing the concept of God on this very ground was discussed. It was pointed out that the characteristics of universality and necessity that Kant attributed to purposefulness were not only based on the grounds of experience. At this point, it was stated that to achieve universality, it is necessary to base on an a priori principle at the same time. The possibility that this principle could be an intention (Alm. Absicht) or a final end (Alm. Endzweck) was discussed. We focused on the request of the reason, which is applied to the conditioned and the finite, to reach the unconditional. It was stated that for Kant, the reason for the transition from teleological judgments to theological judgments was the effort to see purposeful regularity in phenomena. It was pointed out that it is a necessary step of the mind to lead this regularity to a higher telos and even to a creator, to the first being. We emphasized that concerning Kant’s critical philosophy if the concept of God was placed on the ground of natural science and the purposefulness in nature would be explained with this, and this method was used to prove the existence of God that would create an internal and non-permanent narrative. It was discussed whether this claim was an illusion. At this point, the task of the imagination performed with telos was examined. Evaluations about the concept of telos as the common ground of the subjective and the universal were included. As a result, it has been investigated how the search for the constant existing in the human mind can lead him to the existence of a God in the chain of causality. (shrink)
