Science is widely regarded as the most reliable epistemic source of providing knowledge about the world. Policymakers intend to make purposeful changes in the world. The practice of policymakers relying on scientific experts to make informed decisions about which policies to implement is called Evidence Based Policymaking. This thesis provides a perspective from the philosophy of science in order to discuss the justifiability of Evidence Based Policymaking (EBP) with respect to broadly democratic and liberal values. Justifying EBP with broadly democratic (...) and liberal values entails that the practices of EBP promote, or at least are in harmony with, values such as democratic governance and enhancement of people’s freedom and autonomy. Identifying the conditions under which practices of EBP meet such desiderata minimally requires an understanding of how sciences and scientific experts are instrumental in realizing the public’s values, needs, interests, and pursuit of freedom. In order to approach this project, the thesis adopts a philosophical perspective to conceptualize how sciences are supposed to be guided by or promote society’s values, needs, and interests. Specifically, it adopts a perspective from the philosophy of science that focuses on the relationship between science and (societal) values. The kind of philosophy of science perspective on “values in science” that this thesis adopts has two overarching pursuits relevant for the project of the thesis. Firstly, it seeks to inform the debates about which values and non-epistemic considerations are supposed to inform scientific research. For instance, it discusses the proper sources/owners of the non-epistemic desiderata that inform scientific research and the proper social mechanisms to identify these non-epistemic desiderata (e.g. Kourany, 2010; Kitcher, 2011). Second, it offers theories of the non-epistemic values’ proper roles in scientific reasoning and research that specify how their involvement in science does not unduly compromise the epistemic pursuits of science. The values-in-science perspective thereby seeks to balance the instrumental value of science (i.e., its use to pursue certain societal projects and values) with its epistemic authority (i.e., its objectivity, non-dogmatism, and reliability). The thesis advances an understanding of EBP from the perspective of the values in science by addressing issues that come to the fore when EBP is acknowledged as a value-laden practice of informed decision-making.

A differential equation with a known solution is transformed by changing both its dependent and independent variables, and the resulting nonlinear differential equation is then compared with the Schrödinger equation. The method is demonstrated using the confluent hypergeometric differential equation and the solutions to hydrogen, SHO and l=0 Morse potential problems are obtained.

A purely algebraic perturbation theory based on deforming the generators of the dynamical group SU(1, 1) is applied to the l = 0 Morse potential problem with $V(r) = V_0 \left[ {e^{ - 2ar} - 2be^{ - ar} } \right]$ . In particular, perturbations of the form $(e^{ - ar} )^N $ and $(e^{ - ar} )^{ - N} $ are treated explicitly.

In the target article Nijhawan speculates that visual perceptual mechanisms compensate for neural delays so that moving objects may be perceived closer to their physical locations. However, the vast majority of published psychophysical data are inconsistent with this speculation.

Empirical and theoretical foundations for the study of the temporal dynamics of mechanisms contributing to unconscious and conscious processing of visual information; from computational, psychological, neuropsychological, and neurophysiological perspectives.

This paper consists of two parts and has two aims. The first is to elaborate on the historical-philosophical background of Cantor’s notions of infinity in the context of Spinoza’s influence on him. To achieve this aim, in the first part I compare Spinoza’s and Cantor’s conceptions of actual infinity along with their mathematical implications. Explaining the metaphysical, conceptual, and methodological aspects of Cantor’s expansion of the orthodox finitist conception of number of his time, I discuss how he adopts Spinoza’s motifs (...) to overcome the challenges on his way to proposing his transfinite infinites. To achieve the second aim, i.e., to investigate the philosophical foundations of Cantor’s transfinite infinites, I follow a three-step outline analyzing Cantor’s three principles along with their metaphysical and epistemological-linguistic aspects. I analyze the strengths and weak sides of Lakoff and Núñez’s Basic Metaphor of Infinity and Pantsar’s Process → Object Metaphor, then compare their interpretations with mine. I conclude that the metaphors can be improved when their source domains are limited to the target domains they apply to and when supported by a thorough analysis of the historical-philosophical background of their target domains.

It is generally considered and widely accepted that Fakhr al-Dīn al-Rāzī School to be effective in the formation and development of Ottoman intellectual life. However, there are some ʻulamā’ such as Jalāl al-Dīn al-Dawānī, who influenced the Ottoman mindset with both their works and ideas and beyond, they create distinct traditions. Present outline aims to draw attention to this issue through Mu’ayyadzāda ʻAbd al-Raḥmān Efendi, who is a famous disciple and representative of al-Dawānī perspective in Anatolia. In this respect, it (...) introduces the two risālas belongs to him that are important in terms of his theory of nature, and by moving here it points to some questions that need to be answered here and some issues that need to be addressed.

This article discusses the quiddity of the empty set from its epistemological and linguistic aspects. It consists of four parts. The first part compares the concept of _nihil privativum_ and the empty set in terms of representability, arguing the empty set can be treated as a negative and formal concept. It is argued that, unlike Frege’s definition of zero, the quantitative negation with a full scope is what enables us to represent the empty set conceptually without committing to an antinomy. (...) The second part examines the type and scope of the negation in the concept of _nihil privativum_ and the empty set. In the third part the empty set is interpreted as a rigid abstract general term. The uniqueness of the empty set is explained via a widened version of Kripke’s notion of rigidity. The fourth part proposes a construction for the pure singleton, comparing it with Zermelo’s conception of singletons with the Ur-elements. It is argued that the proposed construction does not face the criterion and ontological inflation problems. The first conclusion of the article is that the empty set can be construed as a negative, formal and unique abstract general term, with quantitative negation full in scope. The second conclusion is that the pure singleton constructed out of the empty set construed in this way overcomes the criterion and ontological inflation problems. (shrink)

Pathways to Contemporary Islam: New Trends in Critical Engagement highlights that the current tensions in Islam and the Muslim world are the result of historical dynamics as opposed to an alleged incompatibility between religious tradition and modernity. The emphasis on pathways indicates that critical engagement and contestation have always been intrinsic to the history of Islam. The aim of the book is to elaborate the contemporary pathways and analyse the trends that contest the Islamic intellectual tradition, the relationship between religion (...) and politics, and the individual and collective practice of religion. The collection of essays analyses the current efforts of critical re-engagement with the Islamic intellectual tradition and underlines the historical diversity of Islamic orthodoxies that led to the establishment of various pathways in the practice and role of religion in Muslim societies.

Our visual system can process information at both conscious and unconscious levels. Understanding the factors that control whether a stimulus reaches our awareness, and the fate of those stimuli that remain at an unconscious level, are the major challenges of brain science in the new millennium. Since its publication in 1984, Visual Masking has established itself as a classic text in the field of cognitive psychology. In the years since, there have been considerable advances in the cognitive neurosciences, and a (...) growth of interest in the topic of consciousness, and the time is ripe for a new edition of this text. Where most current approaches to the study of visual consciousness adopt a 'steady-state' view, the approach presented in this book explores its dynamic properties. This new edition uses the technique of visual masking to explore temporal aspects of conscious and unconscious processes down to a resolution in the millisecond range. The 'time slices' through conscious and unconscious vision revealed by the visual masking technique can shed light on both normal and abnormal operations in the brain. The main focus of this book is on the microgenesis of visual form and pattern perception - microgenesis referring to the processes occurring in the visual system from the time of stimulus presentation on the retinae to the time, a few hundred milliseconds later, of its registration at conscious or unconscious perceptual and behavioural levels. The book takes a highly integrative approach by presenting microgenesis within a broad context encompassing visuo-temporal phenomena, attention, and consciousness. (shrink)

Using a metacontrast masking paradigm, prior studies have shown that a target’s color information and form information, can be processed without awareness and that unconscious color processing occurs at early, wavelength-dependent levels in the cortical information processing hierarchy. Here we used a combination of paracontrast and metacontrast masking techniques to explore unconscious color and form priming effects produced by blue, green, and neutral stimuli. We found that color priming in normal observers is significantly reduced when an additional paracontrast mask precedes (...) the target at optimal masking SOAs. However, no reduction of form-priming effects was obtained at similar optimal paracontrast SOAs. We conclude that unconscious color priming depends on an early, wavelength- or stimulus-dependent response of color neurons located at early cortical levels whereas unconscious form priming occurs at later levels.

In this article the authors would like to present a history of the Turkish feminist movement. The roots of the feminist movement go back to the last decades of Ottoman Empire in Turkey when westernisation had started to take place. During the firts decade of the Republic many steps were taken to enable women to get involved in public, political and professional life and to encourage more equality in family matters. Women’s emancipation became a significant symbol of modernity. Kemalist reforms (...) attemted to create a new woman who could take place in public sphere with the men. During the 1970’s the movement of women almost disappeared in nationalist and socialist movements. After the military intervention in 1980 new female actors started to present new demands and change the nature of feminist movement in Turkey. (shrink)

Turkish culture is based on tolerance, the product of the unique Islam–Turkish synthesis. This synthesis is crucial today for a more balanced perception of Islam because it opposes extremism and the terror that is associated with it. The Turkish–Ottoman Empire followed earlier traditions and set up a system based on tolerance towards its ethnically diverse subjects. It was due to this exceptional system assuring stability and freedom of conscience that the Empire was able to hold together people of different religions, (...) languages and races, and to protect and preserve different cultures and languages. This tradition of tolerance and harmony lives on in modern Turkey. Although today there are bound to be certain misinterpretations of Islam, the majority of Turks firmly oppose intolerance and terrorism. (shrink)

El artículo aborda la relación entre Nietzsche y Levinas, en particular se enfrenta a la concepción de cuerpo y narración sostenida por cada autor. En ese sentido se afirma que la aparente distancia que existe entre ambos pensadores puede reducirse a partir de las temáticas que se estudian en este trabajo. A la luz de todo ello, la lectura del cuerpo de Nietzsche y la comprensión de narración de Levinas no habrían sido solo reflexiones filosóficas, sino más bien el pretexto (...) para que ambos pensadores critiquen el pensamiento establecido y propongan, cada uno a su modo, un quehacer filosófico que afecta directamente la existencia humana en cuanto reflexión sobre las formas como se comprende la vida misma.

Fıkıh usulünün dil ve yorum bahislerinde yer alan konulardan biri âmm lafızlardır. İlk dönemlerde umum ifadelerin tanımına, varlığına ve kapsamına dair tartışmalar yer alırken Gazzâlî sonrasında klasik mantığın konularından olan tümeller de tartışmada yerini aldı. Bu makale âmm lafızların gönderimde bulunduğu anlamın tümelliğini sorgulamakta ve klasik sonrası usul düşünürlerinin umum-tümel ilişkisine dair teorik açıklamalarını incelemektedir. Makalenin iddiası şudur: Fıkıh usulünün elfâz bahislerinde ele alınan umum ifadelerin tümellere delâletini savunan ve bunu dilin zihnî suretlere vaz olunmasına bağlayan ilk usulcü Gazzâlî’dir (ö. (...) 505/1111). Fahreddin er-Râzî (ö. 606/1210) ve sonraki dönem usulcüler ise âmm lafızların tümelliğini kabul etmemiş sadece fertleri arasında tümel bir anlamın var olduğunu savunmuştur. Aynı düşünceyi devam ettiren Karâfî (ö. 684/1285), İsfahânî (ö. 688/1289) ve Sübkî (ö. 771/1370), İbn Sînâ’nın (ö. 428/1037) etkisiyle umum ifadeleri tümel önermeler olarak değerlendirirken Teftâzânî (ö. 792/1390) kapsam kavramı üzerinden hem tüm hem tümel olarak görmüştür. Her iki farklı anlayışın öğretilerini eklektik bir tavırla inceleyen Cem‘u’l-cevâmi‘ üzerine şerh ve haşiye yazan usulcüler ise tüm, tümel ve tümel önerme olmak üzere üç farklı kabul sergilemiştir.
