Klasik fizik anlayışını değiştiren kuantum kuramı, bilimsel sahada ilk defa ortaya çıkan indeterminizm olması bakımından felsefe ve teoloji alanlarında da büyük etkiler meydana getirmiştir. Evrene yönelik yeni bir bakış açısı sunan bu kuram, tarihte çığır açarak yepyeni bir dönemi başlatmıştır. Devrim niteliğindeki kuantum kuramı, yirminci yüzyılın en önemli entelektüel başarılarındandır. Atom ve atom altı sistemleri inceleyen kuantum kuramı Max Planck’in kuantum hipoteziyle başlamış, kuramın temel prensipleri yine onun tarafından ortaya konulmuştur. Kuantum kuramı; hiçbir kesinliğin olmadığı, nesnelerin ölçüm yapılıncaya kadar hiçbir (...) özelliğinin bulunmadığı sıradışı bir dünyayı betimlemektedir. Kuantum dünyası; parçacıkların uzayda sürekli şekilde bir var olup bir yok olduğu, bir nesnenin aynı anda evrenin her yerinde bulunabildiği ve bir duvarın içinden rahatlıkla geçebildiği, iki cismin galaksiler arası uzaklıkta bile ışık hızından çok daha hızlı ve anlık bir iletişim hâlinde olabildiği tuhaflıklarla doludur. Bütün bunlar tamamen bilimsel olup gerçek sonuçları ve uygulamaları hem mikrodünyada hem de makro dünyada mevcuttur. Kuantum yasaları hiçbir yasanın edilmediği kadar test edilmiş ve bunlardan istisnasız geçmiştir. İslam düşüncesinde önemli bir yeri olan Gazzâlî, mûcizeyi nedensellik bağlamında tartışmıştır. Mûcizeyi âdetullah teorisi üzerine temellendirerek zorunlu nedenselliği reddetmiştir. Ona göre varlıklar özsel niteliklere sahip değildir, onları da aralarındaki ilişkileri de yaratan hakîkî fail olan Allah’tır. Dolayısıyla onların aralarında gerçekleşen neden-sonuç ilişkisi zorunlu değildir. Bu ilişkideki kuralları koyan da değiştirebilecek olan da Allah’tır. Neden-sonuç ilişkisindeki genel kurallar âdetullah, kurallardaki istisnâî değişiklikler ise mûcizelerdir. Gündelik yaşamdaki genel geçer kurallar (âdetullah) işlemekte olup bilim vs. bu kurallara göre yapılır. Mûcizenin gerçekleşmesi ise düşük bir ihtimal olarak her zaman vardır. Gazzâlî’nin, zorunlu nedenselliğin geçersizliğini ispat bağlamında getirdiği ateşin pamuğu yakması örneğinde ateş ile yanma arasında zorunlu bir ilişki yoktur. Başka bir deyişle ateşin özsel bir yakma özelliği bulunmamaktadır. Ona göre bunların kaynağı tamamen Allah’tır ve esasen âdetullah dışında -zıtların bir arada bulunması gibi muhaller hariç- her türlü ihtimal mevcuttur. Gazzâlî’nin bu görüşleri, günümüz kuantum kuramının neden-sonuç ilişkisine dair verileriyle uyum içindedir. Kuantum kuramına göre de maddenin en küçük yapı birimi olan temel parçacıkların farklı özsel nitelikleri bulunmamaktadır. Onların dünyasında dolayısıyla tüm evrende belirsizlik hakimdir. Her parçacık her an evrenin her yerindedir. Bu belirsizlikler ancak gözlemci etkisiyle/ölçümle belirlenir, böylece varlıklar ve olaylar oluşur. Bu oluşta her türlü ihtimal mevcutken gözlemci etkisi/ölçüm, bunu tek ihtimale düşürür. Kuantum kuramına göre gündelik yaşantıdaki yani makro âlemdeki alışılagelen klasik fizik kurallarının işleme sebebi, olasılıklarının çok yüksek olmasıdır. Fakat çok düşük ihtimalle de olsa sıra dışı ya da tabiat dışı olayların meydana gelmesi mümkündür. Bu ise mûcizelerin imkanını göstermektedir. (shrink)

REN PASSMORE wrote his assessment of British moral philosophy, he lamented that the fifty years which :had elapsed since 1900 had produced nothing beitter than so many variations on utilitarianism. Equally, a lament seems in order over the ourrent state of epistemology. After so many years of grappling with the problem of v,aJidating epistemo1log~cail!l'eailism-consider, for example, the American scene during the first severail decades of this century: Roy Wood Sellars et al. announcing the "new realism '' and George Santayana et al. announcing,the "critical realism "one might have hoped for 1 an oiutcome more reassuring than Hie current £deistic realism. But if the fideism disappoints, its rationalizations fascinate. Take, for examp1e, the trio o.f books discussed herein. They undertake a common project: to forge a raitionaJ justification for realism. They shave other features, not so 1audatory, especiaUy :a merely fideis:tic ioommitment to what might best be deseribed as generic realism, which finally evaporaites into 631 RAYMOND DENNEHY idealism. The mo,sit thait the authors can muster on behalf of realism amounts: to no more than this: " Something (what, we don't know) must e.rist outside our minds heearuse we aict on that premise with considemhle success, not only in daily life hut in scientific prructice, aillld a~l the theories used to explruin it aDJd its successes form a logieally coherent whoJe." In other wo11ds, whait these "defenses'' of rerulism offer is a pragmatic representationalism, organized and ultimaitiely vindi!caited by the ideaJist criterion of coherence and der,iving overai11 inspiration from a blind faith in e~tmmental reality. The tip-off,fa,in the books' titles: Contextual Real-ism, The Many Fa(')es of Realism, and Varieties of Realism. How can you taJk about the "contexts," " v;arieties,'' and "many faces " of realism if__,espreiciaJJy by your own admiss:ion-you cannot identify 11eaJ,ity itself? The answer is found in fideism: you want to affirm extramentaJ reality, even though y;ou find it impossible to justify 1that affirmation,rationaHy. So, in a flush. of ega,1itarian fervur, you aooept au plausible claimants to the title of " reality "; and being unabJ:e to say that any one c~aim­ ant is more or ~ess 11eal than any other, you hope to bring matters to a happy conclusion by apperuling to "varieties," "con- :te:xJts," and "many faces" of rea1ity. Hut the imperatives of life and thought maroe,a harmoniza-,tion of ail1l these " realities'' inevitable if anything resembling tl'IUe and false assertions is to he sav;ed. If, for example, common sense tells us that the11e 1a11e,ice cubes and scienee teHs us that the11e are only indeterminate mass particles, we will want to know how these 1 asse11tions can both be true. Clearly, the V'enerahle correspondence criterion of truth won't do here, is:ince we are fruoed with two oompeting objects of correspondence. It thus becomes necessary to enlist :the aid of the pragmatic theory of tmth to deoide which of the " realities " wil,l be designated " xeal '' in a part:iou~ar set of circumstances. Anticipating PiUtnam's examp~e, we ma.y then say that ice cubes~ and pink ones aJt that__,are real when we wish to mix drinks and that iDJdeterminate mass particles,a~11e reail when we wish UNREAL REALISM 633 to produce a scientific ruoom.mt of the phenomenon caHed " ice cubes." Still,.antil(Jipating Schlagel, not even pragmatism carries us far enough because it depends on knowing which resuJtis are felicitous. We thus turn fo the cohe11ence theory of tmth as our final court of... (shrink)

Neuroscientists are searching for the engram within the conceptual framework established by John Locke's theory of mind. This framework was elaborated before the development of information theory, before the development of information processing machines and the science of computation, before the discovery that molecules carry hereditary information, before the discovery of the codon code and the molecular machinery for editing the messages written in this code and translating it into transcription factors that mark abstract features of organic structure such as (...) anterior and distal. The search for the engram needs to abandon Locke's conceptual framework and work within a framework informed by these developments. The engram is the medium by which information extracted from past experience is transmitted to the computations that inform future behavior. The information-conveying symbols in the engram are rapidly generated in the course of computations, which implies that they are molecules. (shrink)

The last two decades have seen two significant trends emerging within the philosophy of science: the rapid development and focus on the philosophy of the specialised sciences, and a resurgence of Aristotelian metaphysics, much of which is concerned with the possibility of emergence, as well as the ontological status and indispensability of dispositions and powers in science. Despite these recent trends, few Aristotelian metaphysicians have engaged directly with the philosophy of the specialised sciences. Additionally, the relationship between fundamental Aristotelian concepts—such (...) as "hylomorphism", "substance", and "faculties"—and contemporary science has yet to receive a critical and systematic treatment. _Neo-Aristotelian Perspectives on Contemporary Science _aims to fill this gap in the literature by bringing together essays on the relationship between Aristotelianism and science that cut across interdisciplinary boundaries. The chapters in this volume are divided into two main sections covering the philosophy of physics and the philosophy of the life sciences. Featuring original contributions from distinguished and early-career scholars, this book will be of interest to specialists in analytical metaphysics and the philosophy of science. (shrink)

On the occasion of the 50th anniversary of C. S. Lewis’s death, a special annotated edition of his Christian classic, The Screwtape Letters, with notes and excerpts from his other works that help illuminate this diabolical masterpiece. Since its publication in 1942, The Screwtape Letters has sold millions of copies worldwide and is recognized as a milestone in the history of popular theology. A masterpiece of satire, it offers a sly and ironic portrayal of human life and foibles from the (...) vantage point of Screwtape, a highly placed assistant to “Our Father Below.” At once wildly comic, deadly serious, and strikingly original, The Screwtape Letters comprises the correspondence of the worldly-wise devil Screwtape and his nephew Wormwood, a novice demon in charge of securing the damnation of an ordinary young man. For the first time, The Screwtape Letters will be presented in full-text accompanied by helpful annotations in a striking two-color format. These annotations will give fans a deeper, more nuanced understanding of the popular book, providing background information, explanations of terms, historical significance, and excerpts from Lewis’s other works that more fully explain the ideas in this volume. For both expert Lewis fans and casual readers, The Screwtape Letters: Annotated Edition will be a beautiful and insightful guide to a beloved classic. (shrink)

My aim in this article is to introduce readers to the topic of exploratory experimentation and briefly explain how the three articles that follow, by Richard Burian, Kevin Elliott, and Maureen O'Malley, advance our understanding of the nature and significance of exploratory research. I suggest that the distinction between exploratory and theory-driven experimentation is multidimensional and that some of the dimensions are continuums. I point out that exploratory experiments are typically theory-informed even if they are not theory-driven. I also distinguish (...) between research programs and experiments. Research programs that are largely exploratory, such as the ones discussed in these case studies, can involve both exploratory and theory-driven experimentation. (shrink)

I argue that mind-independence realism should be characterised in terms of what I call 'essential', rather than 'modal', independence from our mental lives. I explore the connections between the two kinds of independence, and argue that characterizations in terms of essence respect more intuitions about what realism is, harmonize better with standard characterizations of anti-realism, and avert the threat of subversion from Blackburn's quasi-realist.

We have examined only a few of the basic questions about causal inference that result from Reichenbach's two principles. We have not considered what happens when the probability distribution is a mixture of distributions from different causal structures, or how unmeasured common causes can be detected, or what inferences can reliably be drawn about causal relations among unmeasured variables, or the exact advantages that experimental control offers. A good deal is known about these questions, and there is a good deal (...) more to find out. (shrink)

In his bookMinimal Rationality (1986), Christopher Cherniak draws deep and widespread conclusions from our finitude, and not only for philosophy but also for a wide range of science as well. Cherniak's basic idea is that traditional philosophical theories of rationality represent idealisations that are inaccessible to finite rational agents. It is the purpose of this paper to apply a theory of idealisation in science to Cherniak's arguments. The heart of the theory is a distinction between idealisations that represent reversible, solely (...) quantitative simplifications and those that represent irreversible, degenerate idealisations which collapse out essential theoretical structure. I argue that Cherniak's position is best understood as assigning the latter status to traditional rationality theories and that, so understood, his arguments may be illuminated, expanded, and certain common criticisms of them rebutted. The result, however, is a departure from traditional, formalist theories of rationality of a more radical kind than Cherniak contemplates, with widespread ramifications for philosophical theory, especially philosophy of science itself.

The Cambridge Companion to the Hebrew Bible and Ethics offers an engaging and informative response to a wide range of ethical issues. Drawing connections between ancient and contemporary ethical problems, the essays address a variety of topics, including student loan debt, criminal justice reform, ethnicity and inclusion, family systems, and military violence. The volume emphasizes the contextual nature of ethical reflection, stressing the importance of historical knowledge and understanding in illuminating the concerns, the logic, and the intentions of the biblical (...) texts. Twenty essays, all specially commissioned for this volume, address the texts' historical and literary contexts and identify key social, political, and cultural factors affecting their ethical ideas. They also explore how these texts can contribute to contemporary ethical discussions. The Cambridge Companion to the Hebrew Bible and Ethics is suitable for use in undergraduate and graduate courses in liberal arts colleges and universities, as well as seminaries. (shrink)

Identity theory The doctrine that mental states are identical with physical states was defended in antiquity by Lucretius and in the early modern era by Hobbes. It achieved considerable prominence in the 1950s as a result of the writings of Herbert Feigl, U. T. Place, and J. J. C. Smart. (See, e.g., Smart (1959). These authors developed reasonably precise formulations of the doctrine, clarified the grounds for embracing it, and responded persuasively to a range of objections. More recently it has (...) been defended systematically by Hill (1991) and Papineau (2002). Other contemporary advocates include Loar (1990), McLaughlin (2004), and Polger (2005). The doctrine also figures explicitly or implicitly in the writings of dualists, who are of course concerned to oppose it. Thus, for example, it plays an important role in Kripke’s influential defense of dualism (Kripke 1980). (shrink)
