Open peer commentary on the article “Towards a PL-Metaphysics of Perception: In Search of the Metaphysical Roots of Constructivism” by Konrad Werner. Upshot: Key aspects of Werner’s concerns involve overcoming dualisms. This presupposes an implicit spatial preunderstanding that is neglected in Werner and needs amplification. Diametric and concentric spatial-relational frames for cognition and perception offer a supporting framework for Werner’s interrogation of constructivist roots, to go beyond Cartesian metaphysics and to concretise difference that is not mere dualistic separation.

Despite the frequency of stillbirths, the subsequent implications are overlooked and underappreciated. We present findings from comprehensive, systematic literature reviews, and new analyses of published and unpublished data, to establish the effect of stillbirth on parents, families, health-care providers, and societies worldwide. Data for direct costs of this event are sparse but suggest that a stillbirth needs more resources than a livebirth, both in the perinatal period and in additional surveillance during subsequent pregnancies. Indirect and intangible costs of stillbirth are (...) extensive and are usually met by families alone. This issue is particularly onerous for those with few resources. Negative effects, particularly on parental mental health, might be moderated by empathic attitudes of care providers and tailored interventions. The value of the baby, as well as the associated costs for parents, families, care providers, communities, and society, should be considered to prevent stillbirths and reduce associated morbidity.

Peter Abelard (1079–1142 ce) was the most wide‐ranging philosopher of the twelfth century. He quickly established himself as a leading teacher of logic in and near Paris shortly after 1100. After his affair with Heloise, and his subsequent castration, Abelard became a monk, but he returned to teaching in the Paris schools until 1140, when his work was condemned by a Church Council at Sens. His logical writings were based around discussion of the “Old Logic”: Porphyry's Isagoge, aristotle'S Categories and (...) On Interpretation and boethius'S textbook on topical inference. They comprise a freestanding Dialectica (“Logic”; probably c.1116), a set of commentaries (known as the Logica [Ingredientibus], c. 1119) and a later (c. 1125) commentary on the Isagoge (Logica Nostrorum Petititoni Sociorum or Glossulae). In a work Abelard called his Theologia, issued in three main versions (between 1120 and c.1134), he attempted a logical analysis of trinitarian relations and explored the philosophical problems surrounding God's claims to omnipotence and omniscience. The Collationes (“Debates,” also known as “Dialogue between a Christian, a Philosopher and a Jew”; probably c.1130) present a rational investigation into the nature of the highest good, in which the Christian and the Philosopher (who seems to be modeled on a philosopher of pagan antiquity) are remarkably in agreement. The unfinished Scito teipsum (“Know thyself,” also known as the “Ethics”; c.1138) analyses moral action. (shrink)

In this paper, I will give a three-stage analysis of the origin of phenomenal consciousness. The first one has to do with a non-causal stage. The second one has to do with a causal stage. The third one has to do with a correlation stage. This paper is divided into three sections. In section I, I will discuss a non-causal stage which focuses on finite consciousness as an irreducible emergent property—i.e., a simple non-structural property that is unique to the “emergent” (...) level of reality. I will examine currently dominant accounts of the emergence of phenomenal consciousness—which require consciousness to have some sort of causal link to its base level. Those who think of the emergence of consciousness in casual terms, often have in mind, brain complexity as a source of such causality. However, the causal proposal faces two serious empirically supported objections, namely: the gametes problem and the complexity problem, respectively. The first objection deals with conception (i.e., fertilization) and the impossibility of tracking down/spotting the origin of consciousness at any point during the process of the development of a foetus. The second objection focuses on demonstrating that, no amount of analysis of the physical basis of complex brain will unfold anything substantial about the origin of consciousness. Both of these two objections show why the diachronic account of the origin of the phenomenal consciousness is hard to come by. In section II, I will discuss a causal stage which focuses on, how once it emerges, consciousness enters into the domain of causal interaction with brain states. This is the stage where we come across both ‘the explanatory gap problem’ and ‘the hard problem of consciousness.’ In section III, I will discuss the correlation stage which focuses on the manner in which phenomenal consciousness continues to co-exist with its physical base (e.g., brain). To show this, I will discuss the notion of correlation and its relation to causation. The upshot of my discussion in the above three sections will constitute the view I call the non-causal spontaneous emergence of phenomenal consciousness. According to the view I am proposing, there is no causal-link between strongly emergent property (in this case, consciousness) and its base level—although the base level (as far as we know) serves as a sufficient condition (but not as a necessary condition) for its emergence. In light of this, I conclude this paper by claiming that phenomenal consciousness is a strongly emergent property. (shrink)

Although Antoine Arnauld has been best known to contemporary (...) philosophers as the author of the fourth set of objections to Descartes’ Meditations, interest in Arnauld’s own philosophical thought appears to be on the rise within the Anglo-American philosophical community, as indicated by the publication, within the last eight years, of two new translations of his Des vrayes et des fausses idées (a philosophical polemic against Malebranche) and a new translation of the Port-Royal Logic that Arnauld co-authored with Pierre Nicole. This new collection, from an international group of contributors, is thus well-timed. The two main themes that emerge from the collection as a whole serve to indicate the potential importance of Arnauld scholarship to our understanding of seventeenth century philosophy.The first theme that unites most of the papers is that of the diversity of views that existed within the constellation of philosophers who identified in one way or another with the doctrines of René Descartes. Arnauld was, of course, one such Cartesian. Nevertheless, many of the papers take the differences between Descartes and Arnauld as their starting point. Peter Schouls sets up a general contrast between the modernity of Descartes’ thought, as founded on the validity of subjective consciousness, and the tradition-grounded character of Arnauld’s philosophy. Jill Vance Buroker focuses productively on Arnauld’s and Descartes’ opposing views on the nature of assertion and judgment. Alan Nelson uses Arnauld’s challenge to Descartes’ account of the material falsity of ideas as the basis for a controversial but fascinating reassessment of a range of crucial issues in Descartes scholarship: clarity and distinctness, objective reality, and representation, as well as material falsity. Jean-Luc Solère’s contribution (described further below) documents the fact that significant philosophical debates existed, not [End Page 367] just within Cartesianism, but even within the still narrower Jansenist community that agreed in taking Augustine and Descartes as their philosophical models. In thus highlighting and documenting the diversity and richness of Cartesianism, the collection provides a valuable contribution to the history of philosophy. This theme is also very much present in the essays by Ndiaye, Kremer, and Carraud, which are discussed below.The second theme, shared by the majority of the papers, is that of philosophical theology. As Elmar Kremer remarks in his editor’s introduction (p. ix), while Arnauld himself held that philosophy and theology are distinguishable disciplines, the volume as a whole documents their many interconnections in his work. These interconnections are especially well brought out in the contributions by Kremer, Solère, and Sleigh. Kremer argues that we can understand three of Arnauld’s key departures from Descartes (with respect to the nature of body, the production of sensory ideas, and divine omnipotence) as motivated by his Christian commitments. Solère contends, in his intricate and illuminating essay, that Arnauld’s views about the metaphysical status of known truths (that they are relations in our minds, rather than entities in God grasped by us) are connected to a debate about the savability of non-Christians, and that his disputant, Pierre Nicole, developed an account of implicit or indirect knowledge in order to accommodate his commitment to general grace, a divine illumination had by everyone. Robert Sleigh’s essay considers the difficult question of how Arnauld wished to reconcile his doctrine of efficacious grace with human freedom: Arnauld clearly advocated some sort of compatibilism, but what sort, exactly? Although Sleigh admits that he cannot give an unambiguous defense of a single answer, his map of the territory is very valuable indeed.

I address an intuition commonly endorsed by metaphysicians, that there must be a fundamental layer of reality, i.e., that chains of ontological dependence must terminate: there cannot be turtles all the way down. I discuss applications of this intuition with reference to Bradley’s regress, composition, realism about the mental and the cosmological argument. I discuss some arguments for the intui- tion, but argue that they are unconvincing. I conclude by making some suggestions for how the intuition should be argued for, (...) and discussing the ramifications of giving the justification I think best. (shrink)

This book offers a reassessment of the political philosophy of the British Idealists, a group of once influential and now neglected nineteenth-century Hegelian philosophers, whose work has been much misunderstood. Peter Nicholson focuses on F. H. Bradley's idea of morality and moral philosophy; T. H. Green's theory of the Common Good, of the social nature of rights, of freedom, and of state interference; and Bernard Bosanquet's notorious theory of the General Will. By examining the arguments offered by the Idealists and (...) by their critics the author is able to penetrate the deep layers of hostile comment laid down by several generations of later writers and to show that these ideas, once properly understood, are not only defensible but interesting and important.

In recent years, many philosophers of modern physics came to the conclusion that the problem of how objectivity is constituted (rather than merely given) can no longer be avoided, and therefore that a transcendental approach in the spirit of Kant is now philosophically relevant. The usual excuse for skipping this task is that the historical form given by Kant to transcendental epistemology has been challenged by Relativity and Quantum Physics. However, the true challenge is not to force modern physics into (...) a rigidly construed static version of Kant's philosophy, but to provide Kant's method with flexibility and generality. In this book, the top specialists of the field pin down the methodological core of transcendental epistemology that must be used in order to throw light on the foundations of modern physics. First, the basic tools Kant used for his transcendental reading of Newtonian Mechanics are examined, and then early transcendental approaches of Relativistic and Quantum Physics are revisited. Transcendental procedures are also applied to contemporary physics, and this renewed transcendental interpretation is finally compared with structural realism and constructive empiricism. The book will be of interest to scientists, historians and philosophers who are involved in the foundational problems of modern physics. (shrink)

Problem: Ernst von Glasersfeld’s radical constructivism has been highly influential in the fields of mathematics and science education. However, its relevance is typically limited to analyses of classroom interactions and students’ reasoning. Methods: A project that aims to support improvements in the quality of mathematics instruction across four large urban districts is framed as a case with which to illustrate the far-reaching consequences of von Glasersfeld’s constructivism for mathematics and science educators. Results: Von Glasersfeld’s constructivism orients us to question the (...) standard view of policy implementation as a process of travel down through a system and to conceptualize it instead as the situated reorganization of practice at multiple levels of a system. In addition, von Glasersfeld’s constructivism orients us to understand rather than merely evaluate policies by viewing the actions of the targets of policies as reasonable from their point of view. Implications: The potential contributions of von Glasersfeld’s constructivism to mathematics and science education have been significantly underestimated by restricting the focus to classroom actions and interactions. The illustrative case of research on the application of these ideas also indicates the relevance of constructivism to researchers in educational policy and educational leadership. (shrink)

We describe and analyse how large herbivores strongly diminished a woody vegetation, dominated by the unpalatable shrub Sambucus nigra L. and changed it into grassland. Density of woody species and cover of vegetation were measured in 1996, 2002 and 2012 in the grazed Oostvaardersplassen. In 2002 and 2012 we also measured density and cover in an ungrazed control site. In 2002 we measured intensity of browsing and bark loss of Sambucus shrubs in the grazed and control sites. In the grazed (...) site the density of Sambucus and Salix spp. declined significantly between 1996 and 2012, and large areas changed into grassland. In the control site the density of Sambucus increased significantly during this period, the density of Salix spp. did not change, and the vegetation consisted of a mixture of woody species and a field layer dominated by tall herbs. In 2002 and 2012 the percentages of dead Sambucus shrubs were significantly higher in the grazed site than in the control site. In 2002 the percentages of twigs browsed and ring barked stems of Sambucus shrubs were significantly higher in the grazed site than in the control site. Our results show that debarking caused mature Sambucus shrubs to die, but that heavy browsing may have helped this process. Our results also point to a significant neighbour effect on the break down of Sambucus, suggesting that Aggregational Resistance and Associational Palatability were both active. Essential conditions for the break down of this woody vegetation were the presence of large herbivores, the low ratio between the areas of summer and winter feeding habitats and the competition amongst herbivores. Browsing may have been responsible for seedling death, as seedlings were found only in the control site and not on the old and newly established grasslands in the grazed site. (shrink)

ABSTRACTIn verbal communication, affective information is commonly conveyed to others through spatial terms. This study used a target location discrimination task with neutral, positive and negative stimuli to test the automaticity of the emotion-space association, both in the vertical and horizontal spatial axes. The effects of stimulus type on emotion-space representations were also probed. A congruency effect was observed in the vertical axis: detection of upper targets preceded by positive stimuli was faster. This effect occurred for all stimulus types, indicating (...) that the emotion-space association is not dependent on sensory modality and on the verbal content of affective stimuli. (shrink)

The underdetermination of theory by evidence is supposed to be a reason to rethink science. It is not. Many authors claim that underdetermination has momentous consequences for the status of scientific claims, but such claims are hidden in an umbra of obscurity and a penumbra of equivocation. So many various phenomena pass for `underdetermination' that it's tempting to think that it is no unified phenomenon at all, so I begin by providing a framework within which all these worries can be (...) seen as species of one genus: A claim of underdetermination involves (at least implicitly) a set of rival theories, a standard of responsible judgment, and a scope of circumstances in which responsible choice between the rivals is impossible. Within this framework, I show that one variety of underdetermination motivated modern scepticism and thus is a familiar problem at the heart of epistemology. I survey arguments that infer from underdetermination to some reëvaluation of science: top-down arguments infer a priori from the ubiquity of underdetermination to some conclusion about science; bottom-up arguments infer from specific instances of underdetermination, to the claim that underdetermination is widespread, and then to some conclusion about science. The top-down arguments either fail to deliver underdetermination of any great significance or (as with modern scepticism) deliver some well-worn epistemic concern. The bottom-up arguments must rely on cases. I consider several promising cases and find them to either be so specialized that they cannot underwrite conclusions about science in general or not be underdetermined at all. Neither top-down nor bottom-up arguments can motivate any deep reconsideration of science. (shrink)

In the axiomatic development of the logic of nonrelativistic quantum mechanics it is not difficult to set down certain plausible axioms which ensure that the quantum logic of propositions has the structure of an orthomodular poset. This can be done in a number of ways, for example, as in Gunson [2], Mackey [4], Piron [5], Varadarajan [7] and Zierler [8], and we summarise one of these ways in §2 below.

The Nuremberg Trials of leading National Socialists established the principle that individuals may be legally punished, even by death, for obeying the laws of their country. Is there then a higher law by which enacted valid positive laws may be judged, so that persons subject to such laws would be duty-bound to defy them? In recent years the theory of natural law has been revived by a number of philosophers and jurists, who however often disagree sharply among themselves about the (...) proper methods for defining and deriving natural law. Howard Kainz surveys the history of natural law from its foreshadowing in ancient Greece down to the most recent controversies. Natural Law both introduces the subject to newcomers and sheds fresh light on such figures as Plato, Aristotle, Hume, Kant, Veatch, McInerny, Grisez, and Finnis. (shrink)

We characterise explicitly the decidable predicates on integers of Infinite Time Turing machines, in terms of admissibility theory and the constructible hierarchy. We do this by pinning down ζ, the least ordinal not the length of any eventual output of an Infinite Time Turing machine (halting or otherwise); using this the Infinite Time Turing Degrees are considered, and it is shown how the jump operator coincides with the production of mastercodes for the constructible hierarchy; further that the natural ordinals associated (...) with the jump operator satisfy a Spector criterion, and correspond to the L ζ -stables. It also implies that the machines devised are "Σ 2 Complete" amongst all such other possible machines. It is shown that least upper bounds of an "eventual jump" hierarchy exist on an initial segment.

At the very end of Plato's Philebus Socrates and Protarchus place the goods of a human life in a hierarchy (66a-67b). Previous interpretations of this passage have concentrated upon its relevance to the good human life, including the allowance of (true and pure) pleasures. This view picks up Plato's metaphor of a mixture of reason and pleasure, but the ranking of the goods is emphatically a vertical stratification and not a mixture in which all elements are equally fundamental. In this (...) article I argue that each and all of the higher ranked goods are necessary conditions for the goods of the level immediately below. The ranking represents an attempt to identify as far as possible what is responsible for the characteristics of the good in human life, and therefore to narrow down the definition of the good itself.

J. Kaerst, following a suggestion made by Ranke, conjectured that Diodorus' source for Alexander, whom he identified with Clitarchus, derived information from the mercenaries who served Darius. This conjecture has been developed into an elaborate theory by Sir William Tarn, a theory that has found some favour. He holds that the ‘mercenaries' source’, which I shall henceforth call M, was Diodorus' ‘principal guide [my italics] down to Issus’, and also ‘largely used’ by Curtius ; from certain texts in Curtius Tarn (...) infers that M went down to Darius' death, and he thinks that till that point both Diodorus and Curtius continued to draw upon him, as well as upon other authorities.

This essay explores a variety of important Chinese conceptions of the actual and ideal relationship between human beings and the rest of the natural world. It presents views from the earliest period of historical China, the latter part of the Shang dynasty (ca. 1200–1050 bce), and from representative thinkers of other periods, extending down to the last imperial era, the Qing dynasty (1644–1911 ce). There is a fairly clear line of development from the earliest period, when the Chinese saw the (...) natural realm as chaotic, dangerous and largely inscrutable, to a later view of the world as well ordered, inclined toward human good and more open to understanding. This later view was first expressed during the “Eastern Zhou” (770–221 bce), and reached a mature and systematic form in the following Han dynasty (206 bce–220 ce). Subsequent periods saw remarkable variation in the specific features of this view but its general form – a belief in a well ordered and manageable world, inclined toward human good and open to human understanding – remained dominant throughout subsequent Chinese history.

So why be a good engineer? There are basically three reasons: 1) possible detection and the harm that dishonorable acts might cause, 2) a common responsibility to the professional engineering community, and 3) a negative impact on one’s own integrity when one behaves badly. But what if, in the face of these arguments, one is still not convinced? I must admit that there appears to be no knock-down ethical argument available to change the mind of a person set on behaving (...) badly. There remains the option to act in whatever way one may wish. Engineers must realize however that bad manners and/or immorality and/or illegality, even if undetected, will most likely result in harm to themselves and thus rational behavior should result in honorable conduct of professional duties. While the Viking society of northern Europe was in many ways cruel and crude, they had a very simple code of honor. Their goal was to live life so that when they died, others would say He was a good man . The definition of what they meant by a good man might be quite different by contemporary standards but the principle is important. If engineers conduct their professional lives so as to uphold the exemplary values of engineering, the greatest professional honor would be to be remembered as a good engineer. (shrink)

Human control of action in routine situations involves a flexible interplay between (a) task-dependent serial ordering constraints; (b) top-down, or intentional, control processes; and (c) bottom-up, or environmentally triggered, affordances. In addition, the interaction between these influences is modulated by learning mechanisms that, over time, appear to reduce the need for top-down control processes while still allowing those processes to intervene at any point if necessary or if desired. We present a model of the acquisition and control of goal-directed action (...) that goes beyond existing models by operationalizing an interface between two putative systems—a routine and a non-routine system—thereby demonstrating how explicitly represented goals can interact with the emergent task representations that develop through learning in the routine system. The gradual emergence of task representations offers an explanation for the transfer of control with experience from the non-routine goal-based system to the routine system. At the same time it allows action selection to be sensitive both to environmental triggers and to biasing from multiple levels within the goal system. (shrink)

A Principle of fundamental importance, if it is valid, for the interpretation of the Pentekontaetia is laid down by the authors of A. T.L. iii in its most rigorous terms: it is that Thucydides has set events ‘in proper order … without any deviation whatever’. The conclusion appears to the present writer to be founded ultimately on a false assumption about Thucydides' purpose in these chapters, namely that he set out to write an outline history of the period of fifty (...) years to which he refers in 118.2 and, in effect, in 97. An examination of these passages reveals that it is not the outline of a period as a period that is offered, but rather the account of a particular theme or process falling within the period: his purpose in presenting the theme there defined is to be seen from the setting of the excursus as a unit in Bk. I rather than from the statement in 97.2: the due significance of this last, and of the demarcation of a period in 118. 2, is to be seen only in this wider context. (shrink)

It is now becoming increasingly clear that during the reproductive phase of life and beyond it continues to direct cell renewal (which is essential to combat the chronic environmental stress to which the body is constantly exposed) and counteracts vascular, osteolytic and sometimes oncological insults to the body. Conversely, down‐regulation of hedgehog signalling is associated with ageing‐related diseases such as (...) type 2 diabetes, neurodegeneration, atherosclerosis and osteoporosis. Hence, in this essay we argue that hedgehog signalling is not only important at the start of life, but also constitutes an important anti‐geriatric influence, and that enhanced understanding of its properties may contribute to developing rational strategies for healthy ageing and prevention of ageing‐related diseases.Also watch the Video Abstract.

In lieu of an abstract, here is a brief excerpt of the content:Dharma Bums: The Beat Generation and the Making of Countercultural PilgrimageP. J. JohnstonI believe in the sweetness of Jesus And Buddha— I believe, In St. Francis, Avaloki Tesvara, the Saints Of First Century India A D And Scholars Santidevan And Otherwise Santayanan Everywhere.(Kerouac 1959: 15)Preliminary Polemics“PILGRIM, n. A traveler that is taken seriously.”—Ambrose Bierce, The Devil’s Dictionary 2007: 133As Beat commentator Stephen Prothero describes in his article “On the (...) Holy Road: The Beat Movement as Spiritual Protest” (1991), the Beats and their pilgrimages have most emphatically not been taken seriously. Both critics and scholars have been unkind to members of the Beat generation, and this unkindness has manifested itself in relative neglect of the Beats in all possible aspects of scholarly investigation. But nowhere does this appear more pronounced than in the area of Beat religion. Though some recent scholarship has been picking up from this earlier neglect and it is now [End Page 165] possible to find serious biographies of most of the major Beat writers and some belated attention to the movement as a literary phenomenon, the only book-length treatment of Beat Buddhism I was able to locate (Tonkinson 1995) hardly qualifies as a scholarly work and was published not by an academic press but as a special feature of the Buddhist magazine Tricycle. Prothero hypothesizes that this is because of the movement’s reputation as rebellious and antinomian—in its heyday the movement was characterized in identical unsavory terms by publications representing interests as diverse as Life and Playboy, with the latter describing the Beats as “nihilists” and the former claiming that the Beats were at war with “Mom, Dad, Politics, Marriage, the Savings Bank, Organized Religion, Literary Elegance, Law, the Ivy League Suit and Higher Education, to say nothing of the Automatic Dishwasher, the Cellophane-wrapped Soda Cracker, the Split-Level House and the clean, or peace-provoking H-bomb” (Prothero 1991: 206). Norman Podhoretz of Partisan Review went further still, claiming that the Beats were “hostile to civilization” and that the movement as a whole amounted to “a revolt of the spiritually underprivileged and crippled of soul” and “an affirmation of death” (ibid., 206). One couldn’t ask for a more passionate disavowal of the Beats or a more thorough polemic that the movement was profoundly antireligious.This could not contrast more with the Beats’ representation of their movement and its aims, with Jack Kerouac going so far as to reinterpret the crucial term “Beat” (a term for someone down and out originally borrowed from criminal street jive) as a noun derived from the adjective “beatific,” a specifically religious term familiar from such phrases as “the beatific vision” (ibid., 206–207). Several of the representative Beat writers were practicing Buddhists, influencing the entire movement to such an extent that Buddhist ideas and imagery suffused Beat literature as a whole. Ginsberg and Kerouac especially emphasized the positive and constructive elements of their spiritual vision, arguing that literature such as On the Road and Howl should be understood as religious affirmations of what is good and holy rather than as purely critical undertakings: “For the crucifix I speak out, for the Star of Israel I speak out, for the divinest man who ever lived who was German (Bach) I speak out, for sweet Mohammed I speak out, for Buddha I speak out, for Lao-tse and Chuang-tse I speak out” (ibid., 206–207). Or, as Allen Ginsberg put it less lyrically (and rather more bluntly): “Howl is an ‘Affirmation’ by individual experience of God, sex, drugs, and absurdity... the poems are religious and I meant them to be” (ibid., 207).But for the most part, Beat asseverations in no way diminished scholarly wariness about the Beat movement and its spirituality—as Prothero concludes, “the tendency among literary scholars is to see these [religious] concerns as tangential rather than constitutive” while “historians of American religion who have explored beat spirituality have tended to focus almost exclusively on the beats’ engagement with Zen and then to dismiss that engagement as haphazard” (ibid., 207).It is my contention that the mainstream scholarly neglect of Beat spirituality is in some part...

Ibn KhaldØun’s theory of history has been extensively discussed and interpreted in widely divergent ways by Western scholars. In the context of present debates, it seems most appropriate to read his work as an original and comprehensive version of civilizational analysis (the key concept of ‘umran is crucial to this line of interpretation), and to reconstruct his model in terms of relations between religious, political and economic dimensions of the human condition. A specific relationship between state formation and the broader (...) context of civilizational processes appears as the most central theme. This civilizational approach is then contrasted with the most influential recent Western interpretation, put forward by Ernest Gellner. Gellner translates Ibn KhaldØun’s analysis into functionalist terms and thus tones down its historical and civilizational specificity. The consequences are most obvious when it comes to discussing the unity and diversity of the Islamic world, especially with regard to the Ottoman Empire. (shrink)

I argue that the truthmaker theorist should be a priority monist if she wants to avoid commitment to mysterious necessary connections. In section 1 I briefly discuss the ontological options available to the truthmaker theorist. In section 2 I develop the argument against truthmaker theory from the Humean denial of necessary connections. In section 3 I offer an account of when necessary connections are objectionable. In section 4 I use this criterion to narrow down the options from section 1. In (...) section 5 I argue that the account leads us to priority monism. (shrink)

Critics comment on the simplicity of the jest here, not without reason.1 But the levity also has some sophistication, of a literary kind. For a start,andare aptly long and are carefully left to the end of their clauses and lines for maximum effect. In addition, these striking words, which appear for the first time in Sappho, may well have been deliberate adaptations of two adjectives which had previously occurred only in Homer,2 and they would in any case have called to (...) mind the Homeric ones, because of their close similarity and because there are no other variants of these compounds in surviving literature down to the time of the j poetess.3 At Odyssey11.312 the poet had said of Otus and Ephialtes and at Iliad 7.220, 222, 245, 266 and 11.545 he had described the shield of Ajax asSo, given the epic flavour of Sappho′s epithets, it was amusing of her to include them at all in such a light and frivolous context. There is also pawkiness in the poetess′s application of these terms I with their Homeric tinge to quite different and very mundane objects; and the humour is increased when one takes into account the associations that these words had .This strikes me as an early instance of witty adaptation of epic diction such as is found in Anacreon 358 and 417 PMG.4.
