Objectives: The most principal nutrition source of a bone is nutrient arteries. They are important at every stage of bone development. A nutrient artery enters a bone through the nutrient foramen, the largest hole on the outer surface of the bone. The foramen is important both morphologically and clinically. -/- Methods: A total of 414 adult human dry bones were investigated in this study to identify topographic and morphological features of nutrient foramina in the scapula, clavicle, humerus, radius and ulna. (...) Nutrient foramina were examined with a hand lens. Their dimensions and directions were determined with a 21-gauge needle, and thus major foramina were detected. Positions of nutrient foramina were noted according to surfaces of the bones, and to segments separated as proximal, middle and distal by calculating foraminal index. -/- Results: A single nutrient foramen was found in 71% of our samples. We observed that 94.2% of foramina in the clavicle, 89.3% of foramina in the humerus, 51.3% of foramina in the radius, and 67.7% of foramina in the ulna were located in the middle 1/3 segment of the bones. -/- Conclusion: Our findings were in line with the data in the literature. On account of pathologies associated with the nutrient foramen, our findings may be helpful for surgeons to design applications performed in the region. In addition, we think that our data by contributing to the literature may be a resource for clinicians due to the importance of the nutrient foramen for surgical procedures. (shrink)

Objective: To determine the prevalence of the accessory sacroiliac joint (ASIJ) on both computed tomography (CT) images and dry bones and ultimately, to contribute to the literature. -/- Materials and Methods: CT images archived in the Radiology department of Gaziantep University Medical Faculty obtained from 145 individuals (104 males and 41 females) as well as 92 sacral bones were examined. -/- Results: The prevalence of ASIJ among 92 sacral bones was 15.2%. The ASIJ was more commonly (52%) located at the (...) posterior portion of the SIJ at the level of the second dorsal sacral foramen. In 48% of the bones, ASIJ was identified just above the first dorsal sacral foramen. Unilateral ASIJ was observed in 10.8% and bilateral ASIJ in 4.4% of the sacral bones. On CT images, ASIJ was found in 7.8% of the males and 7.2% of the females. The total prevalence of sacroiliac joint variations was 28.9%, and 6.8% of them were ASIJs. -/- Conclusion: It should be kept in mind that ASIJ may be a source of arthritis and chronic hip pain. The presence of ASIJ should be sought through imaging studies for early diagnosis of ASIJ. (shrink)

This article presents Paul Ricœur’s hermeneutic of the productive imagination as a methodological tool for understanding the innovative social function of texts that in exceeding their semantic meaning, iconically augment reality. Through the reasoning of Rastafari elder Mortimo Planno’s unpublished text, Rastafarian: The Earth’s Most Strangest Man, and the religious and biblical signification from the music of his most famous postulate, Bob Marley, this article applies Paul Ricœur’s schema of the religious productive imagination to conceptualize the metaphoric transfer from text (...) to life of verbal and iconic images of Rastafari’s hermeneutic of word, sound and power. This transformation is accomplished through what Ricœur terms the phenomenology of the iconic augmentation of reality. Understanding this semantic innovation is critical to understanding the capacity of the religious imagination to transform reality as a proclamation of hope in the midst of despair. (shrink)

With the advent of the digital age and new mediums of communication, it is becoming increasingly important for those interested in the interpretation of religious text to look beyond traditional ideas of text and textuality to find the sacred in unlikely places. Paul Ricoeur’s phenomenological reorientation of classical hermeneutics from romanticized notions of authorial intent and psychological divinations to a serious engagement with the “science of the text” is a hermeneutical tool that opens up an important dialogue between the interpreter, (...) the world of the text, and the contemporary world in front of the text. This article examines three significant insights that Paul Ricoeur contributes to our expanding understanding of text. First under scrutiny will be Ricoeur’s de-regionalization of classic hermeneutics culminating in his understanding of Dasein (Being) as “being-in-the-world,” allowing mean-ing to transcend the physical boundaries of the text. Next, Ricoeur’s three-fold under-standing of traditionality/Traditions/tradition as the “chain of interpretations” through which religious language transcends the tem-poral boundary of historicity will be explored. The final section will focus on Ricoeur’s understanding of the productive imagination and metaphoric truth as the under-appreciated yet key insight around which Ricoeur’s philosophical investigation into the metaphoric transfer from text to life revolves.

There is no such thing as moral luck or everyone is profoundly mistaken about its nature and a radical rethinking of moral luck is needed. The argument to be developed is not complicated, and relies almost entirely on premises that should seem obviously correct to anyone who follows the moral luck literature. The conclusion, however, is surprising and disturbing. The classic cases of moral luck always involve an agent who lacks control over an event whose occurrence affects her praiseworthiness or (...) blameworthiness. Close examination of what it is to have control or to lack it reveals the logical space for counterexamples that do not fit the pattern constitutive of moral luck, and so unravel the whole. (shrink)

Recently, the relationship between evolutionary ecology and perceptual science has received renewed attention under perception-mediated selection, a mode of natural selection linking perceptual saliency, rather than veridicality, to fitness. The Interface Theory of Perception (ITP) has been especially prominent in claiming that an organism’s perceptual interface is populated by icons, which arise as a function of evolved, species-specific perceptual interfaces that produce approximations of organisms’ environments through fitness-tuned perceptions. According to perception-mediated selection, perception and behavior calibrate one another as organisms’ (...) capacities to experience and know the objects and properties of their environments lead to responses highlighting certain environmental features selected for survival. We argue this occurs via the Umwelt/Umgebung distinction in ethology, demonstrating that organisms interact with their external environments (Umgebung) through constructed perceptual schema (Umwelt) that produce constrained representations of environmental objects and their properties. Following Peircean semiotics, we claim that ITP’s focus on icons as saliency-simplified markers corresponds to biosemiotics’ understanding of perceptual representations, which manifest as iconic (resembling objects), indexical (referring), or symbolic (arbitrary) modalities, which provide for organisms’ semiotic scaffolding. We argue that ITP provides the computational evidence for biosemiotics’ notion of iconicity, while biosemiotics provides explanation within ITP for how iconicity can build up into indices and symbols. The common contention of these separate frameworks that the process of perception tracks saliency rather than veridicality suggests that digital/dyadic perceptual strategies will be outcompeted by their semiotic/triadic counterparts. This carries implications for evolutionary theory as well as theories of cognition. (shrink)

Nietzsche offers a positive epistemology, and those who interpret him as a skeptic or a mere pragmatist are mistaken. Instead he supports what he calls per- spectivism. This is a familiar take on Nietzsche, as perspectivism has been analyzed by many previous interpreters. The present paper presents a sketch of the textually best supported and logically most consistent treatment of perspectivism as a first- order epistemic theory. What’s original in the present paper is an argument that Nietzsche also offers a (...) second-order methodological perspectivism aimed at enhancing understanding, an epistemic state distinct from knowledge. Just as Descartes considers and rejects radical skepticism while at the same time adopting methodological skepticism, one could consistently reject perspectivism as a theory of knowledge while accepting it as contributing to our understanding. It is argued that Nietzsche’s perspectivism is in fact two-tiered: knowledge is perspectival because truth itself is, and in addition there is a methodological perspectivism in which distinct ways of knowing are utilized to produce understanding. A review of the manner in which understanding is conceptualized in contemporary epistemology and philosophy of science serves to illuminate how Nietzsche was tackling these ideas. (shrink)

In this paper, we discuss some rather puzzling facts concerning the semantics of Warlpiri expressions of cardinality, i.e. the Warlpiri counterparts of English expressions like one,two, many, how many. The morphosyntactic evidence, discussed in section 1, suggests that the corresponding expressions in Warlpiri are nominal, just like the Warlpiri counterparts of prototypical nouns, eg. child. We also argue that Warlpiri has no articles or any other items of the syntactic category D(eterminer). In section 2, we describe three types of readings— (...) "definite", "indefinite" and "predicative"—which are generally found with Warlpiri nouns, including those which correspond to English common nouns and cardinality expressions. A partial analysis of these readings is sketched i n section 3. Since Warlpiri has no determiner system, we hypothesize that the source of (in)definiteness in this language is semantic. More specifically, we suggest that Warlpiri nominals are basically interpreted as individual terms or predicates of individuals and that their three readings arise as a consequence of the interaction of their basic meanings, which are specific to Warlpiri, with certain semantic operations, such as type shifting (Rooth and Partee 1982, Partee and Rooth 1983, Partee 1986, 1987), which universally can or must apply in the process of compositional semantic interpretation.

We analyze Case in terms of independent constraints on syntactic structures — namely, the Projection Principle (inherent Case), the ECP (marked structural Case), and the theory of extended projections (the nominative, a Caseless nominal projection). The resulting theory accounts for (1) the government constraint on Case assignment, (2) all major Case systems (accusative, ergative, active, three-way, and split), (3) Case alternations (passive, antipassive, and ECM), and (4) the Case of nominal possessors. Structural Case may correlate with pronominal agreement because the (...) former can, and the latter must, involve antecedent-government by a functional head. However, neither phenomenon implies the other. (shrink)

We investigate the causal uncertainty surrounding the flash crash in the U.S. Treasury bond market on October 15, 2014, and the unresolved concern that no clear link has been identified between the start of the flash crash at 9:33 and the opening of the U.S. equity market at 9:30. We consider the contributory effect of mini flash crashes in equity markets, and find that the number of equity mini flash crashes in the three-minute window between market open and the Treasury (...) Flash Crash was 2.6 times larger than the number experienced in any other three-minute window in the prior ten weekdays. We argue that (a) this statistically significant finding suggests that mini flash crashes in equity markets both predicted and contributed to the October 2014 U.S. Treasury Bond Flash Crash, and (b) mini-flash crashes are important phenomena with negative externalities that deserve much greater scholarly attention.

Ergative languages make up a substantial percentage of the world’s languages. They have a case system which distinguishes the subject of a transitive verb from that of an intransitive, grouping the latter with the object — that is, the object of a transitive verb and the subject of an intransitive verb are in the same case, which we refer to as the nominative. However, ergative languages differ from one another in important ways. In Greenlandic Eskimo the nominative, whether it is (...) a subject or an object, is syntactically prominent in the clause, much like a subject in English; but in Warlpiri, the nominative is not prominent, more like an object. The variable prominence of the nominative manifests itself as well in the semantics, e.g., default scope of indefinite and quantified nominals. Using data from Greenlandic Eskimo and Warlpiri, and from Hindi, which represents a split ergative system, this paper develops a general theory of case which explains the observed differences amongst ergative languages. In addition, the theory is designed to account for the accusative language type, represented by English. (shrink)

It is common practice in intergenerational justice to set fixed thresholds determining what qualifies as justice. Static definitions of how much and what to save for future generations, however, overestimate human epistemological limits and predictive capacity in regard to uncertainty in social- and ecosystems. Long-term predictions cannot account for the inherent range of contingent variables at play, especially according to contemporary theories of punctuated equilibrium. It is argued that policies deliberately testing ecological limits as currently conceived must be excluded from (...) political calculations to minimize current actions from foreclosing future life quality and options. To better reduce harms to present and future generations and support the stability of just institutions (and the stable environments they depend on) as Rawls and others demand, polities can overcompensate resource allocation to environmental sustainability. Focus on reducing environmental harms benefits both current and future generations, reconciling distributive versus intergenerational justice trade-offs. (shrink)

Microalgae in the wild often form consortia with other species promoting their own health and resource foraging opportunities. The recent application of microalgae cultivation and deployment in commercial photobioreactors (PBR) so far has focussed on single species of algae, resulting in multi-species consortia being largely unexplored. Reviewing the current status of PBR ecological habitat, this article argues in favor of further investigation into algal communication with conspecifics and interspecifics, including other strains of microalgae and bacteria. These mutualistic species form the (...) ‘phycosphere’: the micro-environment surrounding microalgal cells, potentiating the production of certain metabolites through biochemical interaction with cohabitating microorganisms. A better understanding of the phycosphere could lead to novel PBR configurations, capable of incorporating algal-microbial consortia, potentially proving more effective than single-species algal systems.

A core commitment of Bob Hale and Crispin Wright’s neologicism is their invocation of Frege’s Constraint—roughly, the requirement that the core empirical applications for a class of numbers be “built directly into” their formal characterization. According to these neologicists, if legitimate, Frege’s Constraint adjudicates in favor of their preferred foundation—Hume’s Principle—and against alternatives, such as the Dedekind–Peano axioms. In this paper, we consider a recent argument for legitimating Frege’s Constraint due to Hale, according to which the primary empirical (...) application of the naturals is transitive counting, or answering ‘how many’-questions using numerals. We make two claims regarding Hale’s argument. First, it fails to legitimate Frege’s Constraint in virtue of resting on unsupported and highly contentious assumptions. Secondly, even if sound, Hale’s argument would vindicate a version of Frege’s Constraint which fails to adjudicate in favor of Hume’s Principle over alternative characterizations of the naturals.

This critical edition is the first ever publication of Hale's Of the Law of Nature, which previously existed only in manuscript form. After discussing and defining the law in general, Hale examines the natural law in particular, its discovery and divine origin, and how it relates to both biblical and human laws. Hale's treatise, which was likely written as part of his personal meditations, and was circulated among English lawyers after his death, reveals not only the close (...) relationship between law and theology in his thought, but also the importance of natural law to early modern legal thought.

Steven Hales and Jennifer Johnson—building off their (2014) work as well as Hales (2015, 2016)—have recently conducted two studies in Philosophical Psychology (2018) that show that there is a relationship between optimism and folk assessments of luck. Hales and Johnson use these results to argue that there is no such thing as luck. Instead, they claim that the concept is highly subjective and a cognitive illusion and that what we are in need of is an error theory. After reviewing Hales (...) and Johnson’s position, I levy four objections against their view. First, they ignore the fact that luck involves a chanciness condition. Second, their standards for what it means to be a useful philosophical theory are too high. Third, their view ignores the fact that there are various accounts of value in the literature and assumes a kind of relativism that few people would be willing to accept. Lastly, their error theory is not supported by the empirical evidence. Because of these problems, Hales and Johnson’s argument is not a serious threat to extant accounts of luck. (shrink)

Review of Bob Hale's "Necessary Beings: An Essay on Ontology, Modality, and the Relations Between Them". Oxford: Oxford University Press 2013, ISBN 9780199669578.

This review is a critical evaluation of the main points of Steven D. Hales’ significant book: Relativism and the Foundations of Philosophy. To that end, I will first summarize his major line of argument pointing out to the richness and significance of the book. After that, I will argue that Hales’ account of intuition is subject to the challenge shown by some recent works written on the topic, and that it postulates a concept of knowledge that opposes Gettier’s one, without (...) arguing why it is so. And, I will show that except rational intuition, none of the methods adopted by Hales are adequate to acquire beliefs about philosophical propositions. Next, I will argue that his method of wide reflective equilibrium is committed to foundationalism and conservatism, and that all what his criticism of skepticism show is that skepticism is true. Also, I will try to show that his form of perspectival relativism is committed to the problem of infinitum; it is incompatible with his foundationalism. It is powerless regarding some forms of skepticism, sharing the same source with some others. It is not progressive, and not perspectival enough regarding Goldman’s view, naturalists’ view, and its alternatives. And, if it is perspectival enough, then it refutes itself. (shrink)

Bob Hale’s distinguished record of research places him among the most important and influential contemporary analytic metaphysicians. In his deep, wide ranging, yet highly readable book Necessary Beings, Hale draws upon, but substantially integrates and extends, a good deal his past research to produce a sustained and richly textured essay on — as promised in the subtitle — ontology, modality, and the relations between them. I’ve set myself two tasks in this review: first, to provide a reasonably thorough (...) (if not exactly comprehensive) overview of the structure and content of Hale’s book and, second, to a limited extent, to engage Hale’s book philosophically. I approach these tasks more or less sequentially: Parts I and 2 of the review are primarily expository; in Part 3 I adopt a somewhat more critical stance and raise several issues concerning one of the central elements of Hale’s account, his essentialist theory of modality. (shrink)

Recently, Kit Fine's (1994) view that modal truths aretrue in virtue of,grounded in, orexplained byessentialist truths has been under attack. In what follows we offer two responses to the wave of criticism against his view. While the first response is pretty straightforward, the second is based on the distinction between, what we call,Reductive Finean EssentialismandNon-Reductive Finean Essentialism. Engaging the work of Bob Hale onNon-Reductive Finean Essentialism, we aim to show that the arguments against Fine's view are unconvincing, while we (...) acknowledge the presence of a deep standoff between the two views.

A very influential idea in the epistemology of modality is that we acquire knowledge of metaphysical modality through knowledge of essence. As a consequence, the epistemology of essence becomes crucial in the attempt to answer the question of how we come to know modal propositions. In this paper I investigate Lowe’s and Hale’s approach to the epistemology of essence and argue that both of them remain in a crucial, structural sense incomplete. Systematizing this criticism against Lowe and Hale, (...) I then break down desiderata of what I call a structurally complete picture of the epistemology of essence. Finally, I discuss Husserl’s epistemology of essence and defend it against a notorious objection. However, Husserl’s approach also seems to remain incomplete, due to its appeal to imagination, which operates on the basis of background assumptions that are themselves in need of justification. I indicate, however, that a Husserlian theory of intuitive awareness of universals might supply us with (direct) justification of these background assumptions and, hence, that we might be able to paint a structurally complete picture of the epistemology of essence with Husserlian means.

This paper asks whether a necessity can be the source of necessity. According to an influential argument due to Simon Blackburn, it cannot. This paper argues that although Blackburn fails to show that a necessity cannot be the source of necessity, extant accounts fail to establish that it is, with particular focus on Bob Hale’s essentialist theory and Christopher Peacocke’s ‘principle-based’ theory of modality. However, the paper makes some positive suggestions for what a satisfactory answer to the challenge must (...) look like. (shrink)

In Necessary Beings, Bob Hale addresses two questions: What is the source of necessity? What is the source of our knowledge of it? He offers novel responses to them in terms of the metaphysical notion of nature or, more familiarly, essence. In this paper, I address Hale’s response to the first question. My assessment is negative. I argue that his essentialist explanation of the source of necessity suffers from three significant shortcomings. First, Hale’s leading example of an (...) essentialist explanation merely asserts that the nature of an entity explains some necessity, but leaves unexplained how it does so. Second, his essentialist explanation of particular necessities introduces new necessities that remain unexplained. Third, Hale’s version of essentialism presupposes a controversial metaphysical theory of properties, for which he offers no defense. (shrink)

Fine, Lowe and Hale accept the view that necessity is to be explained by essences: Necessarily p iff, and because, there is some x whose essence ensures that p. Hale, however, believes that this strategy is not universally applicable; he argues that the necessity of essentialist truths cannot itself be explained by once again appealing to essentialist truths. As a consequence, Hale holds that there are basic necessities that cannot be explained. Thus, Hale style essentialism falls (...) short of what Wilsch calls the explanation-challenge (EC) for the metaphysics of necessity. Without endorsing the EC, I argue that Hale’s argument for basic, unexplained necessities fails due to a misunderstanding of the structure of essentialist explanations. Getting clear about the structure of essentialist explanations of necessity leads to a re-evaluation of crucial circularity- and regress-arguments that have been discussed in the debate about essentialism.

In a lot of domains in metaphysics the tacit assumption has been that whichever metaphysical principles turn out to be true, these will be necessarily true. Let us call necessitarianism about some domain the thesis that the right metaphysics of that domain is necessary. Necessitarianism has flourished. In the philosophy of maths we find it held that if mathematical objects exist, then they do of necessity. Mathematical Platonists affirm the necessary existence of mathematical objects (see for instance Hale and (...) Wright 1992 and 1994; Wright 1983 and 1988; Schiffer 1996; Resnik 1997; Shapiro 1997 and Zalta 1988) while mathematical nominalists, usually in the form of fictionalists, hold that necessarily such objects fail to exist (see for instance Balaguer 1996 and 1998; Rosen 2001 and Yablo 2005). In metaphysics more generally, until recently it was more or less assumed that whatever the right account of composition—the account of under what conditions some xs compose a y—that account will be necessarily true (for a discussion of theories of composition see Simons 1987 and van Inwagen 1987 and 1990; the modal status of the composition relation is explicitly addressed in Schaffer 2007; Parsons 2006 and Cameron 2007). Similarly, it has generally been assumed that whatever the right account is of the nature of properties, whether they be universals, tropes, or whether nominalism is true, that account will be necessarily true (though see Rosen 2006 for a recent suggestion to the contrary). In considering theories of persistence it has been widely held that whether objects endure or perdure through time is a matter of necessity (Sider 2001; though see Lewis 1999 p227 who defends contingent perdurantism). And with respect to theories of time it is frequently held that whichever of the A- or B-theory is true is necessarily true. A-theorists often argue that there is time in a world only if the A-theory is true at that world (see for instance McTaggart 1903; Markosian 2004; Bigelow 1996; Craig 2001) while B-theorists often argue that the A-theory is internally inconsistent (Smart 1987; Mellor 1998; Savitt 2000 and Le Poidevin 1991). Once again, we find a few recent contingentist dissenters. Bourne (2006) suggests that it is a contingent feature of time that it is tensed, and thus that the A-theory is contingently true. Worlds in which there exist only B-theoretic properties are worlds with time, it is just that time in those worlds time is radically different to the way it is actually. Other defenders of the B-theory, though not expressly contingentists, do offer arguments against versions of the A-theory that try to show that such A-theories theories are inconsistent with the actual laws of nature (see for instance Saunders 2002 and Callender 2000); these arguments, at least, leave room for the possibility that the A-theories in question are contingently false (at least on the assumption that the laws of nature are themselves contingent, an assumption that not everyone accepts). Despite some notable exceptions, necessitarianism has flourished in many, if not most, domains in metaphysics. One such exception is Lewis’ famous defence of Humean supervenience as a contingent claim about our world. Lewis does not argue that necessarily, the supervenience base for all matters of fact in a world is nothing but a vast mosaic of local matters of particular fact. Rather, he thinks that we have reason to think that our world is one in which Humean supervenience holds (see Lewis 1986 p9-10 and 1994). Another exception to the necessitarian orthodoxy is to be found in the lively debate about the modal status of the laws of nature. Here, if anything, contingentism has been the dominating force, with it generally being held that there are possible worlds in which different laws of nature hold (this view is defended by, among others, Lewis 1986 and 2010; Schaffer 2005 and Sidelle 2002). Necessitarian dissenters hold that the laws of nature are necessary, frequently because they think it is necessary that fundamental properties have the causal or nomic profiles they do (see for instance Shoemaker 1980 and 1988; Swoyer 1982; Bird 1995; Ellis and Lierse 1994). Nevertheless, when it comes to thinking about the nature of the laws themselves, the necessitarian presumption is back on firm footing. Though there is disagreement about whether the laws are generalisations that feature in the most virtuous true axiomatisation of all the particular matters of fact (often known as the Humean view of laws and defended by Ramsey 1978; Lewis 1986 and Beebee 2000) or whether laws are relations of necessity that hold between universals (a view defended by Armstrong 1983; Dretske 1977; Tooley 1977 and Carroll 1990) no one has seriously suggested that it might be a contingent matter which of these is the right account of laws. The necessitarian orthodoxy is not surprising since metaphysics is largely an a priori process. While a priori reasoning may be used to determine whether a proposition is necessary or contingent, it is not well placed (in the absence of a posteriori evidence) to determine whether a contingent proposition is actually true or false. Since metaphysicians aim to tell us which principles are true in which worlds, on the face of it the discovery that metaphysical principles are contingent seems to make part of the task of metaphysics epistemically intractable. In what follows I consider two reasons one might end up embracing contingentism and whether this would lead one into epistemic difficulty. The following section considers a route to contingent metaphysical truths that proceeds via a combination of conceptual necessities and empirical discoveries. Section 3 considers whether there might be synthetic contingent metaphysical truths, and the final section raises the question of whether if there were such truths we would be well placed to come to know them.

Yirminci yüzyıl bilimde büyük değişim ve dönüşümlerin gerçekleştiği bir dönemdir. Bu yüzyıl içerisinde moleküler biyoloji, kuantum fiziği, genetik mühendisliği ve biyoteknoloji gibi çeşitli bilimlerin temellerinin atıldığı, bilimsel keşifler ve yenilikler neticesinde kuramların ve teknolojilerin hızla geliştiği ve bu gelişmelerin insanlık tarihini köklü bir şekilde etkilediği bir dönem olmuştur. Yirminci yüzyılda bilimsel ilerleme önceki dönemlerden çok daha hızlı bir oranda gerçekleşmiş ve toplumsal yaşam üzerindeki etkisinin daha derin olduğu gözlemlenmiştir. Bu nedenle yirminci yüzyıl genellikle icatların ve teknolojik gelişmelerin yüzyılı olarak adlandırılmaktadır (...) çünkü bilimsel keşiflerin sayısı artmakla birlikte çok sayıda bilim insanı mevcut teknolojiyi daha etkin bir şekilde kullanarak çalıştıkları alanlarda kapsamlı sonuçlara ulaşmışlardır. Dolayısıyla bilim ve teknoloji bu süre zarfında geçmişte olduğundan çok daha yakın hale gelmiştir. Bununla birlikte, bilimin ilerlemesinin hızlı bir şekilde devam etmesi ve mevcut araştırmaların önemli bir kısmının tarihsel bir bakış açısıyla incelenemeyecek kadar yeni ve çok sayıda olması nedeniyle bu yüzyıldaki bütün bilimsel gelişmelerden ve disiplinlerden bahsetmek mümkün değildir. Bu sebeple yazının kapsamını daraltmak açısından yirminci yüzyılda bilimi ve teknolojiyi en çok etkileyen alan olan fizik bilimindeki önemli konulara değinmek bu dönemin ruhunu anlamak ve bilimin dönüşümüne yönelik bir kavrayışa sahip olmak açısından daha uygun gözükmektedir. Bu bağlamda, çalışmada Dünya’mızı ve evreninin işleyişini anlama konusunda başvurduğumuz disiplinlerden biri olan fizik biliminde yirminci yüzyılda devrimsel bir düşünce olarak karşımıza çıkan Albert Einstein’ın özel ve genel görelilik kuramına yer verilmekle birlikte aynı zamanda günümüzde etkileri bilimsel ve teknolojik düzeyde devam eden kuantum mekaniğine yönelik genel bir perspektif sunulmaktadır.

The fourteen papers in this collection offer a variety of original contributions to the epistemology of modality. In seeking to explain how we might account for our knowledge of possibility and necessity, they raise some novel questions, develop some unfamiliar theoretical perspectives, and make some intriguing proposals. Collectively, they advance our understanding of the field. In Part I of this Introduction, I give some general background about the contemporary literature in the area, by sketching a timeline of the main tendencies (...) of the past twenty-five years or so, up to the present debates. Next, I focus on four features that largely characterize the latest literature, and the papers in the present collection in particular: (i) an endorsement of the importance of essentialism; (ii) a shift to a “metaphysics-first” approach to modal epistemology; (iii) a focus on metaphysical modality as opposed to other kinds of modality; and (iv) a preference for non-uniform modal epistemology. In Part II, I present the individual papers in the volume. These are organized around the following four chapters, based on their topic: (A) Skepticism & Deflationism; (B) Essentialism; (C) Non-Essentialist Accounts; (D) Applications. -/- LIST OF CONTRIBUTORS: Francesco Berto; Stephen Biggs & Jessica Wilson; Justin Clark-Doane; Philip Goff; Bob Hale; Frank Jackson; Mark Jago; Boris Kment; Antonella Mallozzi; Graham Priest; Gabriel Rabin; Amie Thomasson; Anand Vaidya & Michael Wallner; Jennifer Wang. -/- The volume is dedicated to the memory of Bob Hale. -/- .

Kit Fine famously objected against the idea that essence can be successfully analyzed in terms of de re necessity. In response, I want to explore a novel, interesting, but controversial modal account of essence in terms of intrinsicality and grounding. In the first section, I will single out two theoretical requirements that any essentialist theory should meet—the essentialist desideratum and the essentialist challenge—in order to clarify Fine’s objections. In the second section, I will assess Denby’s improved modal account, which appeals (...) to the notion of intrinsicality, and argue that it is untenable. In the third section, I will explain how, when combined with a modal-existential criterion, a hyperintensional account of intrinsicality—in the same vein as Bader (J Philos 110(10): 525–563, 2013) and Rosen (in: Hale and Hoffman (eds) Modality: Metaphysics, logic, and epistemology, Oxford, OUP, 2010)—can help successfully address Fine’s counterexamples. In the fourth section, I will evaluate how this novel analysis of essence stands with respect to sortal, origin, and natural kinds essentialism and discuss potential objections and difficulties.

Fictionalists maintain that possible worlds, numbers or composite objects exist only according to theories which are useful but false. Hale, Divers and Woodward have provided arguments which threaten to show that fictionalists must be prepared to regard the theories in question as contingently, rather than necessarily, false. If warranted, this conclusion would significantly limit the appeal of the fictionalist strategy rendering it unavailable to anyone antecedently convinced that mathematics and metaphysics concern non-contingent matters. I try to show that their (...) arguments can be resisted by developing and defending a strategy suggested by Rosen, Nolan and Dorr, according to which the fiction-operator is to be analysed in terms of a counterfactual that admits of non-trival truth-values even when the antecedent is impossible.

There has been much debate recently on the question whether essence can explain modality. Here, I examine two routes to an essentialist account of modality. The first is Hale's argument for the necessity of essence, which I will argue is — notwithstanding recent attempted defences of it — invalid by its very structure. The second is the proposal that it is essential to essential truth that it is necessary. After offering three possible versions of the view, I will argue (...) that each fails to provide a metaphysical explanation of necessity in terms of essence. (shrink)

In his 2014 article “Motivations for Relativism as a Solution to Disagreements”, Steven Hales argues that relativism is a plausible disagreement resolution strategy for epistemically irresolvable disagreements. I argue that his relativistic strategy is not adequate for disagreements of this kind, because it demands an impossible doxastic state for disputants to resolve the disagreement. Contrarily, Fogelin’s :1–8, 1985) theory of deep disagreement does not run into the same problems. Deep disagreements, according to Fogelin, cannot be resolved through argumentation because the (...) conditions for argumentation are lacking in such contexts. I advance the view that deep disagreements arise due to differences in disputants’ mutually supporting interrelated beliefs. This view avoids the hurdles caused by the tiered structure of support found at the heart of Hales’s view on disagreement: the assumption that belief and perspective can be separated, and that disagreement is located.

Certain advocates of the so-called “neo-logicist” movement in the philosophy of mathematics identify themselves as “neo-Fregeans” (e.g., Hale and Wright), presenting an updated and revised version of Frege’s form of logicism. Russell’s form of logicism is scarcely discussed in this literature and, when it is, often dismissed as not really logicism at all (in light of its assumption of axioms of infinity, reducibility and so on). In this paper I have three aims: firstly, to identify more clearly the primary (...) meta-ontological and methodological differences between Russell’s logicism and the more recent forms; secondly, to argue that Russell’s form of logicism offers more elegant and satisfactory solutions to a variety of problems that continue to plague the neo-logicist movement (the bad company objection, the embarrassment of richness objection, worries about a bloated ontology, etc.); thirdly, to argue that neo-Russellian forms of logicism remain viable positions for current philosophers of mathematics.

Çağdaş epistemoloji içerisinde, dışsalcı, güvenilirci ve erdeme dayalı epistemolojik tartışmaların bir benzerini, dini epistemoloji içerisinde etkili bir şekilde yer edinen ve reformcu epistemoloji olarak bilinen yaklaşım üzerinden görebilmek mümkündür. Alvin Plantinga, Nicholas Wolterstorff ve William Alston gibi filozofların öne çıktığı bu yaklaşımın ana iddiası, kanıta ya da argümana dayanmaksızın, Tanrı’nın varlığına inanmanın bütünüyle doğru, rasyonel, makul ve güvenilir olacağı şeklindeki bir tezdir. Kanıtın, gerekçelendirme için zorunlu bir koşul olmadığı fikri, algısal deneyimlerin gerekçelendirilmesine benzer şekilde, dini deneyimlerin de öyle olduğu ve (...) dolayısıyla, aynı epistemik statüye sahip olması gerektiğini öne süren, eşitlik tezine dayanır. İlk ortaya çıktığı günden bugüne, üzerinde çokça konuşulan ve tartışılan bir yaklaşım olan reformcu epistemoloji, özellikle son beş yıl içerisinde, oldukça farklı bir hale gelmiştir. Zira bu yaklaşımı, kanıtsalcılıkla uyumlu, erdem epistemolojisiyle bağlantılı ve diğer teistik dinler üzerinden değerlendiren yeni çalışmalar ortaya çıkmıştır. Bu nedenle, bu makalede, reformcu epistemoloji ana hatlarıyla ele alınmıştır. Beraberinde, ona yöneltilen itirazlara değinilmiş ve sonrasında, bahsi geçen yenilik iddiaları soruşturulmaya çalışılmıştır. Son olarak, teistik inancın rasyonalitesiyle ilgili, farklı bir bakış açısı sunulmuştur. (shrink)

Dinî tecrübe Friedrich Schleiermacher (ö.1768) ile önem kazanan ve William James’in (ö.1842) eserleriyle din felsefesinde teistik delillerin içine dahil olan bir delildir. Dini tecrübelerin birçok şekilde meydana geldiği iddia edilmektedir. Bunlardan biri de sezgidir. Bu bildirinin amacı sezgisel bilginin Tanrı’nın varlığına delil olup olmadığını ortaya koymaktır. Sezgisel yetenek, insanın fiziksel gelişimine (yani beyin) paralel olarak gelişen bir yetidir ve zihnin gelişmesiyle birlikte kapasitesi artmaktadır. Önce çocukta duygusal bir sezgi hakim iken (4-7 yaş), daha sonra çocuğun somut işlemlere geçmesiyle sezgisel yetenek (...) somutla ilişkili hale gelir. (7-11 yaş) Ve somut nesne ve durumlar (deney ve pratikler) çocuğun sezgisel yeteneğinin gelişmesine yol açar. En son aşamada yani soyut işlemler döneminde (11-17 yaş) çocuğun beyninde prefrontal lobun gelişmesine bağlı olarak akli muhakeme gelişir ve bunun etkisiyle sezgisel yetenek, akli verileri kullanarak soyut sezgiye yönelir. Sezgisel yetenek böylece üç dönemin özelliklerini gösterebilir; çocukluktan aldığı duygusal sezgi ve somut/nesnenin çağrıştırdığı somut sezgi ve aklın dış dünyadan aldığı bilgileri zihinsel süreçlerden geçirerek işlemesi sonucu gelişen akılcı sezgi. O nedenle insanlarda tek bir sezgiden bahsetmek yanlıştır. Sezginin üç türü birbiriyle eş güdümlü olarak bilgiyi elde etmek için çalışır. Bu üç sezgi türünden akılcı sezgiye önem veren İbn Sina, sezgi bilgisini rasyonel, epistemolojik alana dahil eder. Yaptığı ilim sınıflamasında sezgi bilgisini deneye dayalı bilgi türü olarak görür ve akla/deneye dayalı bir sezgi anlayışı geliştirir. Bu sezgi anlayışı, peygamberliği rasyonel bir temele oturtmak ve irrasyonel olmadığın açıklamak için de kullanır. Kudsi akla sahip peygamberler üstün zekalarının etkisiyle güçlü sezgiye sahip olurlar ve vahiy alırlar. Vahiy alan sezgisel yetenek diğer insanlarda ortaya çıkıp dini tecrübeleri şekillendirebilir mi? Peygamberlerin vahiy tecrübesini taklit ederek kendilerinde yüksek sezgisel yeti olduğunu savunan bazı kişiler (veli) ilham yoluyla bilgi elde ettiklerini iddia etmişlerdir. Dini tecrübe delilinde bu tür tecrübeler dini delil olarak sayılmaktadır. Fakat bu sezgisel bilginin kaynağı duygu mudur, somut bir gösterge (deney) midir yoksa akıl mıdır? İlham ürünü olan eserlerde her zaman duygu vardır ve bu tür ifadeler insanı duygunun hakim olduğu zihinsel bir duruma götürür. Fakat vahiy tecrübesinde duygunun yanında, somut dünyanın varlığı ve akla dayalı bir sezginin olduğu da vurgulanmaktadır. O nedenle sezgisel bilgi ürünü vahiy üç tür sezgi bilgisine dayalı iken, ilham ürünü olan sezgisel bilgi sadece duyguya dayalıdır. O nedenle ‘dini’ bir delil olarak değil ‘mistik’ bir delil olarak değerlendirmeyi hak eder. (shrink)

In these pages, we expose the main traits of the doctrine of providence of Saint Albert the Great, according to his systematic works, mainly his Summa of Theology.

Albert also restates the reflections of different authors like Boethius or Saint John of Damascus and he gives his personal solution to the complex (...) questions of providence, destiny and contingency of the world.

In these pages, we expose the main traits of St. Albert the Great’s doctrine of providence and fate, considered by Palazzo the keystone of his philosophical system. To describe it we examine his systematic works, primarily his Summa of Theology. His discussion follows clearly the guidelines of the Summa of Alexander of Hales, in order to delve into the set of problems faced over the centuries by theological tradition. Albert also restates the reflections of different authors like Boethius or Saint (...) John of Damascus but, in his Summa he incorporates to his reflections also the noteworthy book of Nemesius of Emesa, De natura hominis, which includes some pages on providence. Albert gives his personal solution to the complex questions of providence, destiny and contingency of the world. His conception of providence is developed in the frame of the creative power of the almighty God. God’s knowledge is necessary and inerrant and his providential purposes are infallible, but that does not mean that every event is necessary. He does not communicate His own proprieties to the creatures. In order to understand this problem, Albert recalls the notion of hypothetical necessity coined by Boethius in an Aristotelian framework and the difference between 'necessitas consequentis' and 'necessitas consequentiae' proposed by Alexander of Hales. He also develops his account of providence, closely linked to the topic of fate. However, it would be exaggerated to deem his position deterministic. (shrink)

Neo-Fregeans such as Bob Hale and Crispin Wright seek a foundation of mathematics based on abstraction principles. These are sentences involving a relation called the abstraction relation. It is usually assumed that abstraction relations must be equivalence relations, so reflexive, symmetric and transitive. In this article I argue that abstraction relations need not be reflexive. I furthermore give an application of non-reflexive abstraction relations to restricted abstraction principles.

La rinascita negli ultimi decenni di un nutrito dibattito intorno alla nozione di analiticità dopo le critiche a suo tempo mosse da Quine alla batteria di nozioni utilizzate da Rudolf Carnap (ad esempio, postulati di significato, regole semantiche, definizioni implicite, convenzioni e stipulazioni esplicite) prende le mosse da una riflessione critica sulle argomentazioni di Quine e tenta, da un lato, di approfondire meglio il legame fra analiticità e conoscenza a priori, e, dall’altro, di capire meglio il ruolo che la definizione (...) può svolgere nella costituzione del significato e nella formulazione di verità concettuali. Questa nuova concezione è detta “epistemica” ed ha fra i suoi più autorevoli fautori Crispin Wright, Bob Hale e Paul Boghossian. Boghossian, al pari di molti filosofi critici della nuova concezione epistemica, come Timothy Williamson, conviene però con Quine nel sostenere che gli enunciati analitici hanno portata fattuale e vertono anch’essi sul mondo, oltre che sul linguaggio. Anche per questa ragione essi possono rendere possibile una genuina estensione delle nostre conoscenze. Tuttavia una seconda linea di obiezioni facenti capo dapprima a Paul Horwich, e in seguito agli stessi Wright e Hale, mette in evidenza rispettivamente due difficoltà corrispondenti alle questioni dell’arroganza e dell’accettazione. In questa discussione una parte importante è svolta dalla ripresa e della discussione del condizionale di Carnap, impiegato per rendere conto del ruolo che i termini teorici svolgono nel quadro dell’intera teoria cui appartengono, senza con ciò sposare le conseguenze dell’olismo quineano. La tesi centrale che questo lavoro cerca di rendere plausibile è che una lettura attenta degli ultimi scritti di Carnap mostri come il carattere aperto che egli attribuisce ai termini teorici in ragione, sia dello loro intrinseca indeterminatezza, sia delle revisioni imposte dalle scoperte scientifiche, è perfettamente compatibile con la fattorizzazione del contenuto di una teoria scientifica data in una parte linguistica, il condizionale di Carnap, riguardante la costituzione del significato di un certo termine teorico, e nella sua controparte empirica, che consente di registrare l’impatto dell’esperienza sulla teoria in questione. Se praticabile, questa concezione può a buon diritto entrare nel novero delle teorie epistemiche dell’analiticità, senza accampare alcuna pretesa di far rivivere i fasti della conoscenza a priori classica.

This paper aims to provide hyperintensional foundations for mathematical platonism. I examine Hale and Wright's (2009) objections to the merits and need, in the defense of mathematical platonism and its epistemology, of the thesis of Necessitism. In response to Hale and Wright's objections to the role of epistemic and metaphysical modalities in providing justification for both the truth of abstraction principles and the success of mathematical predicate reference, I examine the Necessitist commitments of the abundant conception of properties (...) endorsed by Hale and Wright and examined in Hale (2013), and demonstrate how a two-dimensional approach to the epistemology of mathematics is consistent with Hale and Wright's notion of there being non-evidential epistemic entitlement rationally to trust that abstraction principles are true. A choice point that I flag is that between availing of intensional or hyperintensional semantics. The hyperintensional semantic approach that I advance is a topic-sensitive epistemic two-dimensional truthmaker semantics. I countenance a hyperintensional semantics for novel epistemic abstractionist modalities. I suggest that observational type theory can be applied to first-order abstraction principles in order to make abstraction principles recursively enumerable. Epistemic and metaphysical states and possibilities may thus be shown to play a constitutive role in vindicating the reality of mathematical objects and truth, and in providing a conceivability-based route to the truth of abstraction principles as well as other axioms and propositions in mathematics.

Quine (1960, "Word and object". Cambridge, Mass.: MIT Press, ch. 2) claims that there are a variety of equally good schemes for translating or interpreting ordinary talk. 'Rabbit' might be taken to divide its reference over rabbits, over temporal slices of rabbits, or undetached parts of rabbits, without significantly affecting which sentences get classified as true and which as false. This is the basis of his famous 'argument from below' to the conclusion that there can be no fact of the (...) matter as to how reference is to be divided. Putative counterexamples to Quine's claim have been put forward in the past (see especially Evans (1975, "Journal of Philosophy", LXXII(13), 343-362. Reprinted in McDowell (Ed.), "Gareth Evans: Collected papers." Oxford: Clarendon Press.), Fodor (1993, "The elm and the expert: Mentalese and its semantics." Cambridge, MA: Bradford)), and various patches have been suggested (e. g. Wright (1997, The indeterminacy of translation. In C. Wright & B. Hale (Eds.), "A companion to the philosophy of language" (pp. 397-426). Oxford: Blackwell)). One lacuna in this literature is that one does not find any detailed presentation of what exactly these interpretations are supposed to be. Drawing on contemporary literature on persistence, the present paper sets out detailed semantic treatments for fragments of English, whereby predicates such as 'rabbit' divide their reference over four-dimensional continuants (Quine's rabbits), instantaneous temporal slices of those continuants (Quine's rabbitslices) and the simple elements which compose those slices (undetached rabbit parts) respectively. Once we have the systematic interpretations on the table, we can get to work evaluating them. (shrink)

Contemporary discussions of expressivism in metaethics tend to run together two quite different antidescriptivist views, and only one of them is subject to the objection about compositional semantics pressed most recently by Schroeder (following Dreier, Unwinn, Hale, Geach and others). Here I distinguish the two versions of expressivism and then go on to suggest that those sympathetic to the second sort of expressivism might improve their account of normative vocabulary and the way it figures in reasoning by making what (...) may seem like a somewhat surprising comparison between normative vocabulary and logical vocabulary. I argue that this comparison brings into view the initial steps towards a third antidescriptivist view in metaethics, which we may see as a pragmatist improvement on the second version of expressivism.

Mantık, yirminci yüzyıldaki gelişimi bakımından ele alındığında, matematik, bilgisayar bilimi, dilbilim ve felsefe gibi alanlarla sıkı kavramsal bağlantılar kuran bir disiplin haline gelmiştir. Tüm bu alanların gündelik dilde izi sürülen anlamalar, anlaşmalar, anlatmalar vb. edimler için birşeyler söyleyebileceğini ya da yapabileceğini varsayabiliriz. Ancak bu varsayım gündelik dilin mantığıyla ya da mantıksızlıklarıyla doğrudan başedebilecek bir anlama yetisi kazanmanın kolay bir yolu olduğu anlamına gelmez. Modern mantık matematikseldir ve gündelik dilde bir kolaylık sağlamaz; aksine işleri olduğundan da karmaşık hale getirir.

A little essay on the notion of person in Albert the Great. He bases on Alexander of Hales and develops his notion of person from the classical definition of Boethius.

Genetics: Medical, Theological and Ethical Aspects Tibbi, Dini ve Etik Boyutlariyla Genetik -/- Genetik bilimi biyolojinin botanik ve zooloji alanındaki uygulamalarını aşarak, sınırlarını önce antropolojiye sonra tıbba doğru hızla genişletmiştir. Öyle ki artık biyokimyadan onkolojiye kadar neredeyse tüm biyomedikal disiplinler, genetiğin kavramları, ilkeleri ve metodolojisi ile aşılanmıştır. Modern tıbbın uygulama alanında geniş bir yer tutan genetik bilimi, bir hastalığa dair risk analizi, teşhis ve tedavi seçeneklerinin belirlenmesi, prognozun değerlendirilmesi gibi klinik uygulamanın farklı evrelerinde söz sahibi olmaktadır. İçinde bulunduğumuz 21. yüzyılda (...) ise bu etkileşim eskisinden daha da güçlü hale gelerek devam etmektedir. Genetik biliminin klinikteki etkilerinin kapsamlı bir şekilde değerlendirildiği bu kitap, tüm dünyada tıbbın seyrini değiştirecek gelişmelere zemin teşkil eden genetik disiplininin olumlu ve olumsuz etkileri hakkında okuyucuya yetkili ağızlardan bilgiler taşımayı ve daha net bir fikir oluşturmayı hedeflemektedir. Kitapta dört ana bölüm bulunmaktadır. İlk bölümde doğum öncesi genetik uygulamalara, ikinci bölümde doğum sonrası (çocuk ve erişkinde) genetik testlere, üçüncü bölümde tıbbi genetiğin sıcak tartışma konusu olan Spinal Müsküler Atrofi’ye (SMA) ve dördüncü bölümde ise genetik bilgiyi felsefi bakışla ele alan makalelere yer verilmiştir. Genetiğin tıp pratiğini değiştirici ve dönüştürücü etkisine multidisipliner bir yaklaşımla ışık tutmayı amaçlayan bu eserin genetik hakkındaki Türkçe literatüre katkıda bulunmasını ümit ediyoruz.

Gazali'nin hayatını 1095 yılında geçirdiğini söylediği krize göre üç döneme ayırmamız mümkündür. Kriz öncesi dönem, kriz dönemi (1095) ve kriz sonrası dönem. Bu dönemlerde akla ve felsefeye bakışı değişmiştir dolayısıyla felsefî ilimlerden sayılan matematik ilmine bakışı da değişmiştir. Gazali kriz öncesi ve kriz dönemlerinde aklı eleştirmekle birlikte çok sistematik bir eleştiri yaptığı söylenemez. Gazali bu dönemde felsefe yorumlarında 'felsefi/bilimsel aklı" din açısından zararlı görmemektedir hatta zaman zaman olumlu yanlarından bahsetmektedir. Makasıdu’l Felasife ve Tehafütü’l Felasife ‘de akılla ilgili mevzulara değinmiş, bazı (...) felsefî ilimlerin dinle alakalı olmadığını, din açısından fayda veya zarar vermediğini ifade etmiş ama temelde felsefi aklın “sadece dini (metafizik) konulara” yetmeyeceği kanaatine varmıştır. Fakat bu dönemde o, felsefeyi 'dinileştirme' çabasının bir sonucu olarak akıl eleştirisiyle karşımıza çıkmaktadır. Aklın, felsefenin ve felsefî ilimlerin (mantık, astronomi, fizik… vb.) kökenini Kur’an’a dayandırmış ve filozofların bütün bu ilimlerin ‘tümellerini’ dinden öğrendiklerini iddia etmiştir. Böylece Gazali, akılla bir teoloji kurmanın mümkün olmadığını ispatlayarak yani dini ‘akla uygun hale getirme’ girişimlerinin önüne geçerek ‘aklı ve bütün aklî ilimleri dine uygun hale’ getirmek için vahye ve mistik tecrübeye dayalı yeni bir sistem kurmuştur. Dinî akıl, vahyi anlar ve uygular. Kriz sonrası dönemde bütün felsefî sistemleri dinî ve mistik/gnostik bir düşünce etrafında yorumlayan Gazali'de akıl tamamen dinileşmektedir. Avam ilimleri seviyesine indirdiği felsefî (tıp, astronomi, kimya, biyoloji, mantık, matematik vs.) ve dinî ilimleri (kelam, fıkıh ve tefsir) mistik bir zihniyetle yeniden ele alır. Felsefî ilimlerin esası dinîdir ve insanlar bu ilimleri peygamberlerden öğrenmiştir. Kelam ilmi, aklî bir ilim değil, dini bir ilimdir, kelamı kullanarak akli hükümler vermekten vazgeçip sadece dini ve uhrevi hükümler vermesi sağlanmalıdır. Fıkıh ilmi de aklî bir ilim değil dini bir ilimdir ve fıkıh alimleri sadece ahiretle ilgili hüküm verilmelidir. Bunlardan daha üstün olan ise havas ilimleridir. Havas ilmi Gazali'ye göre gnostik tasavvuf öğretisidir. Dünyevî akıl insanı yanılttığı ve ona güvenilmez olduğu için akıl yerine peygamberin vahyi gelmelidir ve ondan sonra vahye benzerliği dolayısıyla "velinin ilhamı" yer almalıdır. Bu ise ilk başta dini anlaması için gerekli olan ‘dinî akıl” ve daha sonra ruh, aşk ve nur yoluyla elde edilmektedir. (shrink)
