I Pletho's Date of Death In 1976 I denied the correctness of the commonly held date of 1452 for Pletho's death. I argued instead for 1454. The difference of two years meant not only that Pletho lived to see the fall of Constantinople in 1453, but also that a whole series of works in the Plato-Aristotle controversy had to be redated. The basis for the 1452 date is a notice found amid other notes by an unknown hand on the last (...) folio of the fifteenth-century manuscript M. 15 in the University Library in Salamanca and in another series of notes in the hand of Pletho's disciple and admirer Demetrius Raoul Kabakes on f. 50v of Gr. 495 of the Bayerisches Staatsbibliothek, Munich. With only trivial variation, both notes state that Master Gemistus died on the first hour of Monday, 26 June in the fifteenth Indiction. Since the only year in this period in which 26 June falls on a Monday in the fifteenth Indiction is 1452, Pletho's date of death seems well established. Though Kabakes was a bizarre character whose trademark was, in Bidez's phrase, an orthographe fantasiste, the fact that he wrote the notice in Munich Gr. 495 might be viewed as strenghtening its credibility. Futhermore, since Dositheus, Metropolitan of Monembasia seems to have died on 1 September 1452 and on blank folios (ff. 7v–8r) in MS Venice, Bibl. Marc., Zan. Gr. 333 (= 644) Bessarion wrote his memorial verses on Pletho and then his memorial verses on Dositheus, one can argue that in the summer of 1452 Bessarion first heard of Pletho's death and then a few months later of Dositheus'. Nonetheless, the death notice is certainly wrong. (shrink)

In 1924 W. W. Tarn published an article in which he attempted to prove that the mother of Philip V of Macedon was the Epirot princess Phthia. Previously all historians had accepted the statement of Eusebius that Philip was the son of Demetrius II and Chryseis, whom, after the death of her husband, the Macedonians gave in marriage to Antigonus Doson. Despite the cogency of Tarn's arguments, his theory has been rejected by both Beloch and Dinsmoor, who adhere to (...) the traditional view. This problem of the identity of Philip's mother is one of considerable importance, and consequently in this paper I intend to collect the evidence once again and subject it to a careful analysis. The results will be found strongly to corroborate Tarn's contention. (shrink)

Demetrius Chrysoloras was a Byzantine anti-Unionist and anti-Thomist theologian. He was in the service of John VII Palaeologus and a member of the court of the Emperor Manuel II Palaeologus. He wrote theological, philosophical, astronomical, and rhetorical works.

We are sceptical of concerns over the opacity of algorithmic decision tools. While transparency and explainability are certainly important desiderata in algorithmic governance, we worry that automated decision-making is being held to an unrealistically high standard, possibly owing to an unrealistically high estimate of the degree of transparency attainable from human decision-makers. In this paper, we review evidence demonstrating that much human decision-making is fraught with transparency problems, show in what respects AI fares little worse or better and argue that (...) at least some regulatory proposals for explainable AI could end up setting the bar higher than is necessary or indeed helpful. The demands of practical reason require the justification of action to be pitched at the level of practical reason. Decision tools that support or supplant practical reasoning should not be expected to aim higher than this. We cast this desideratum in terms of Daniel Dennett’s theory of the “intentional stance” and argue that since the justification of action for human purposes takes the form of intentional stance explanation, the justification of algorithmic decisions should take the same form. In practice, this means that the sorts of explanations for algorithmic decisions that are analogous to intentional stance explanations should be preferred over ones that aim at the architectural innards of a decision tool.

In lieu of an abstract, here is a brief excerpt of the content:The Elizabethan Bacchae STEPHEN ORGEL Euripides’s Bacchae, with its antic hero and celebration of the joys of revenge, would seem to be especially relevant to Elizabethan drama, an ancestor of The Spanish Tragedy or Hamlet. In fact, however, it seems to have been practically unknown to the Elizabethans. With the new ProQuest version of EEBO (Early English Books Online) it is now possible to search early English books for (...) specific references; so I paired the name Euripides with books printed in England before 1640 to see what came up. I got 474 hits. Many of these, of course, were duplicates, appearing in works that were issued in multiple editions—the actual figure, however, was still something over three hundred. Most of those, however, were cases in which Euripides’s name simply appears in a list of famous ancient authors. Citations which actually quoted Euripides for the most part indicated no knowledge of the work cited, but were only bits of wisdom that might have come from any of the multitude of collections of aphorisms and moral stories throughout the period. There was only one English edition of a play of Euripides in Greek, The Trojan Women, published by John Day in 1575— continental editions were, of course, easily obtainable, but it must be to the point that English publishers did not see a sufficient market to produce them domestically; and there were no subsequent editions of Day’s Trojan Women. As for The Bacchae, I found only a single case where I believe it is being cited, and in a context, moreover, that indicates some familiarity with the play. John Bishop’s Beautiful Blossoms, a collection of historical anecdotes published in 1577, recounting the history of Demetrius, king of Macedonia, says, “Then fled Demetrius unto Thebes, where one scoffingly applied vnto him that verse arion 28.3 winter 2021 64 the elizabethan bacchae of Euripides: he came vnto the Dyrcean springs, and Ismenus, his divine and goodly fourme and shape being chaunged in to a mortall.”1 This is a version of a bit of Dionysus’s opening speech, I am here at the springs of Dirce, the river Ismenos, Changing my shape from divine to mortal... There is no reason to assume that John Bishop (about whom I can learn nothing) knew the play, but he is certainly citing someone who did. The play, then, to the Elizabethans was either practically unknown or deliberately ignored. It was not translated into English until the 1780s, and then two translations were published within a year of each other—for the English, it was an enlightenment and romantic text. Schlegel’s Lectures on Dramatic Art and Literature (delivered 1806, published 1846) and Nietzsche’s Birth of Tragedy (1872) were the works that established The Bacchae as the quintessential Greek tragedy, though for Nietzsche, ironically, the two destroyers of the Greek tragic sense, the two great cultural villains, were Euripides the ironist and Socrates the arch-rationalist. But Nietzsche sees Euripides, at the end of his life, having a major change of heart, realizing that Dionysus was simply too powerful to be expunged from art and society; and The Bacchae was thus the fullest expression of this tragic truth. The problems with this argument are manifold: Euripides the ironist is quite evident in The Bacchae, so it hardly represents a change of heart; and the claims of the irrational are fully present in his earlier plays, for example, in Hippolytus, where all the poetic energy is in expressing the uncontrollable violence of passion, and the virtues of morality and self-control are meagre indeed. The essay was soundly refuted in its own time, and Nietzsche withdrew and recanted it. Its celebrity is a modern phenomenon: whatever its historical defects, it speaks to the dangerous attractions of unreason. There is a perverse element in Nietzsche’s argument, too: Dionysus, as the embodiment of revelry, is surely as essential Stephen Orgel 65 to comedy as to tragedy; and one could press this further. At the end of The Symposium, Socrates tells Agathon and Aristophanes, tragic and comic dramatists, that their arts (or crafts: the word is techne) are essentially the same. Heavy weather has...

The purpose of this book is to give a coherent account of the different perspectives on science and technology that are normally studied under various disciplinary heads such as philosophy of science, sociology of science and science policy. It is intended for students embarking on courses in these subjects and assumes no special knowledge of any science. It is written in a direct and simple style, and technical language is introduced very sparingly. As various perspectives are sketched out in this (...) book, the reader moves towards a consistent conception of contemporary science as a rapidly changing social institution that has already grown out of its traditional forms and plays a central role in society at large. It will appeal to students in a wide range of scientific disciplines and complement well Professor Ziman's earlier books. (shrink)

Kant’s philosophy of science takes on sharp contour in terms of his interaction with the practicing life scientists of his day, particularly Johann Blumenbach and the latter’s student, Christoph Girtanner, who in 1796 attempted to synthesize the ideas of Kant and Blumenbach. Indeed, Kant’s engagement with the life sciences played a far more substantial role in his transcendental philosophy than has been recognized hitherto. The theory of epigenesis, especially in light of Kant’s famous analogy in the first Critique, posed crucial (...) questions regarding the ‘looseness of fit’ between the constitutive and the regulative in Kant’s theory of empirical law. A detailed examination of Kant’s struggle with epigenesis between 1784 and 1790 demonstrates his grave reservations about its hylozoist implications, leading to his even stronger insistence on the discrimination of constitutive from regulative uses of reason. The continuing relevance of these issues for Kant’s philosophy of science is clear from the work of Buchdahl and its contemporary reception. (shrink)

The danger of human operators devolving responsibility to machines and failing to detect cases where they fail has been recognised for many years by industrial psychologists and engineers studying the human operators of complex machines. We call it “the control problem”, understood as the tendency of the human within a human–machine control loop to become complacent, over-reliant or unduly diffident when faced with the outputs of a reliable autonomous system. While the control problem has been investigated for some time, up (...) to this point its manifestation in machine learning contexts has not received serious attention. This paper aims to fill that gap. We argue that, except in certain special circumstances, algorithmic decision tools should not be used in high-stakes or safety-critical decisions unless the systems concerned are significantly “better than human” in the relevant domain or subdomain of decision-making. More concretely, we recommend three strategies to address the control problem, the most promising of which involves a complementary coupling between highly proficient algorithmic tools and human agents working alongside one another. We also identify six key principles which all such human–machine systems should reflect in their design. These can serve as a framework both for assessing the viability of any such human–machine system as well as guiding the design and implementation of such systems generally. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy after ChristJohn O'CallaghanConsider the words of Justin Martyr written in the middle of the second century after the birth of Christ and after Justin's conversion to Christianity:Philosophy is indeed one's greatest possession, and is most precious in the sight of God, to whom it alone leads us and to whom it unites us, and in truth they who have applied themselves to philosophy are holy men.1In addition to (...) the praise heaped upon the philosophers, among whom Justin had counted himself before his conversion,2 the text is one of the earliest pieces of evidence for the historical reality of Christian intellectual engagement with pagan or secular philosophy. Whether that engagement proved spiritually fruitful or sterile in any particular age or any particular tradition of philosophy, Christian intellectuals have often sought out engagement with philosophy as an inherent task of the intellectual life of the Church, in order to pursue and develop the understanding of Christian revelation and the mode of life informed by it. One lasting result of the impetus represented by Justin is to be found even now in the normative requirement in Catholic education that, at a certain stage of development, anyone who receives a [End Page 49] serious Catholic education must be introduced to serious philosophical reflection on where we came from, what we are, and where we are born to go.In addition, one of the general points John Henry Newman made in The Idea of a University is that the human mind looks for unity in the diversity of intellectual disciplines it pursues. In search of this unity, it seeks a kind of primary discipline that takes into account the truths discovered throughout the other disciplines as it seeks to understand what it can of the whole of reality, not just its parts. But Newman also pointed out that, in the absence of such a unifying discipline, practitioners of each particular discipline will often claim for their particular discipline the prize of being primary—of being the discipline by which all others must be understood and judged.3Take classical and modern physics. A familiar claim of some physicists, but even more so of non-physicist physicalists, is that physics is the fundamental intellectual discipline for understanding what is real. All reality, living reality, historical reality, moral reality, indeed perhaps even literary reality, must be reduced to reality as described by the physicists or rejected as unreal or epiphenomenal, or in a kinder, gentler vein, non-reductively emergent and supervenient. Whichever position is taken, whether reduction, non-reductive emergence, or epiphenomenalism, the thought is that the real work of the really real is done by reality as described by physics, either in its actual contemporary state or, more likely, in an idealized future state always on the horizon of where physics presently is. We are really atoms spinning ceaselessly in the void, mostly empty space, the warp and woof of a four-dimensional space-time manifold, or congeries of strings in an even more bizarre thirteen-dimensional manifold, or whatever was said most recently to surpass what was said before that by the leading physicists in California or Cambridge.However, anyone who has actually practiced physics knows that, even when uttered by a physicist, these are not claims of physics, but about physics. What prompts them is the sense that there is no intellectual discipline other than contemporary physics itself that can both understand the achievements of physics and integrate them into a larger intellectual comprehension of reality as a whole. These claims about physics nicely display Newman's point about the way in which a particular discipline, in the absence of a larger more comprehensive discipline, can take on an importance for its practitioners well beyond its disciplinary limits. [End Page 50]In the case of physics, if a more comprehensive unifying discipline is not to be found, this attitude is not entirely unjustified, for Newman's point is partly Aristotelian. Aristotle had pointed out that, if one cannot show that unchangeable, and thus non-physical beings, exist, then what Aristotle called "first philosophy" would just be physics as he understood it, the science of...

Nikolaos Kavasilas was a notable lay theologian of the Greek Orthodox Church. He is regarded as one of the most profound Byzantine theologians of the fourteenth century and one of the foremost Marian theologians in the Greek patristic tradition. He was an original exponent of anthropocentric Mariology and Christocentric theology. A prolific author renowned for his liturgical and sacramental writings, but also concerned with social and political issues. He lived in a period of political strife and theological controversy. He was (...) a younger contemporary of Gregorios Palamas, a close friend of Demetrius Cydones and an advisor to the Emperor John VI Cantacuzenus. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Are There Failed Persons?John O'CallaghanIntroductionAre there failed persons? Yes. However, before explaining what a failed person is, it will be good to consider closely a very significant part of our society to get a sense of what it thinks a failed person is, since my account of what a failed person is is markedly different. It is important to think about the question of failed persons because there (...) are growing movements here and abroad aimed at killing by medical means human beings who are judged in some sense to be failed persons, human beings who do not count as persons according to a common societal notion of persons, a social-psychological notion of persons.The question for anyone who lives within this society with its notion of failed persons is whether one will take part in and support this movement toward killing human beings or avoid it, indeed whether one will push back against it. It is easy enough to fall into a trap of thinking about failed persons the way much of our society does. One's complicity in adopting the social-psychological notion of person contributes to enabling the acceptance of such killing, even if one believes one would never perform the killing act. My effort here is precisely to push back against such killing, by pushing back against the notion of persons that animates it.The killing of human beings by our society is not simply confined to abortion, as it has been legally and widely available here in the United States for almost fifty years now. Recent political discussions in the wake of the Dobbs decision have made it clear that many political leaders think such killing ought to be allowed all the way up until birth, and perhaps after. Relatively [End Page 1123] recently there was an article in a mainstream bioethics journal by Alberto Giubilini and Francesca Minerva arguing that what most people would take to be cases of infanticide should be renamed, per their title, "After-Birth Abortion."1 The article was not about the moral legitimacy of either infanticide or abortion. The moral legitimacy of those acts for various reasons was taken as a given by the authors. In the case of euthanizing infants, they noted the expanding number of arguments for it among philosophers, the desire for guidelines for doing it among members of the medical profession, and the protocols for it established in places like the Netherlands.The authors argued that in the case of newborns, including healthy newborns, killing them should not be considered infanticide or euthanasia.2 They distinguished abortion from both euthanasia and infanticide. Euthanasia involves killing a human person, where a person is understood to be a being that can experience itself as having interests that can be harmed. "We take 'person' to mean an individual who is capable of attributing to her own existence some (at least) basic value such that being deprived of this existence represents a loss to her."3 Euthanasia, when justified, is justified by being in the best "interests" of the person killed. Infanticide involves euthanizing children.However, the authors claim that a newborn is not a person in the sense of "person" specified. So, the authors' term "after-birth abortion" is a terminological distinction based upon denying that a newborn is a child, children being persons. They also assume that infants are children as they understand "child." So not being a child, a newborn cannot be an infant. Not being an infant, killing it cannot be infanticide or euthanasia, again as the authors define those terms.4 Instead, killing the newborns, healthy or not, should be thought of as having the same moral weight as an abortion before birth, and thus rather than being called infanticide or euthanasia, it should be called "after-birth abortion."5Killing a newborn then is "ethically permissible" in just the same circumstances and for the same reasons as abortion is ethically permissible. Among [End Page 1124] the "ethically permissible" circumstances for killing newborns, including perfectly healthy newborns, are that the "well-being of the family is at risk" with respect to "social, psychological, economic" factors,6 but also the fact...

The imagery we adopt when recalling the personal past may involve different perspectives. In many cases, we remember the past event from our original point of view. In some cases, however, we remember the past event from an external “observer” perspective and view ourselves in the remembered scene. Are such observer perspective images genuine memories? Are they accurate representations of the personal past? This chapter focuses on such observer perspectives in memory, and outlines and examines proposals about the nature of (...) such imagery.

The earliest writer who deserves to be called a psychologist is Hobbes; and if we consider the time when he wrote, we cannot fail to be surprised at what I may term his prevision of the most important results which have now been established by science. He was the first clearly to sound the note which has ever since constituted the bass, or fundamental tone, of scientific thought. Let us listen to it through the clear instrumentality of his own language:-.

The leading hypothesis concerning the “reuse” or “recycling” of neural circuits builds on the assumption that evolution might prefer the redeployment of established circuits over the development of new ones. What conception of cognitive architecture can survive the evidence for this hypothesis? In particular, what sorts of “modules” are compatible with this evidence? I argue that the only likely candidates will, in effect, be the columns which Vernon Mountcastle originally hypothesized some 60 years ago, and which form part of the (...) well-known columnar hypothesis in neuroscience—systems that cannot handle gross cognitive functions as distinct from strictly exiguous subfunctions. This is in stark contrast to the modules postulated by much of cognitive psychology, cognitive neuropsychology, and evolutionary psychology. And yet the fate of this revised notion is unclear. The main issue confronting it is the effect of the neural network context on local function. At some point the effects of context are so strong that the degree of specialization required for modularity is not able to be met. Still, despite indications from neuroimaging that peripheral and central systems deploy shared circuitry, some skills clearly do seem to display modularization and autonomy. This article: provides an in-depth analytical and historical review of the fortunes of modular thinking in cognitive science; offers a systematic calibration of brain regions in terms of degrees of functional specificity and robustness; and suggests another way of accounting for the partially encapsulated character of expertise and other highly practiced skills without having to resort to domain-specific modules.

The past two decades have witnessed a revival of interest in multiple realization and multiply realized kinds. Bechtel and Mundale’s (1999) illuminating discussion of the subject must no doubt be credited with having generated much of this renewed interest. Among other virtues, their paper expresses what seems to be an important insight about multiple realization: that unless we keep a consistent grain across realized and realizing kinds, claims alleging the multiple realization of psychological kinds are vulnerable to refutation. In this (...) paper I argue that, intuitions notwithstanding, the terms of their recommendation make it impossible to follow, while also misleadingly insinuating that its application virtually guarantees mind-brain identity. Instead of a matching of grains, what multiple realization really requires is a principled method for adjudicating upon differences between tokens. Shapiro’s (2000) work on multiple realization can be understood as an attempt to adumbrate just such a method. While his “causal relevance” criterion can easily be mistaken for Bechtel and Mundale’s grain requirement, my analysis reveals exactly where and why these two tests diverge. (shrink)

What makes ethical accounts natural law ethical is, I argue, commonly misrepresented in teaching within much of the philosophical academy. Yet those immersed in the field of natural law and ethics rarely give definitions/brief characterisations of what makes ethical accounts natural law ethical. I suggest theoretical reasons for the lack. I argue that bringing natural law into ethics is best understood as leading to theoretically unitary accounts, not simply collections of positions detachable from each other: an overlooked and significant point (...) when defending natural law ethical accounts. My arguments throughout rely on the metaethical/normative ethical distinction, which is relatively little used in the natural law literature. I argue that the distinction helps clarify what is distinctive of natural law ethical accounts in general, especially to the secular contemporary philosophical academy, where appreciation of natural law ethical accounts is commonly appreciably lower than in philosophical contexts with a religious ethos.

Contemporary society operates beyond safe boundaries of the Earth system. Returning to a safe operating space for humanity within Earth system boundaries is a question of justice. The relevance of the economy—and thus of business—for bringing society back to a safe and just operating space highlights the importance of business ethics research for understanding the role of business in Earth system justice. In this commentary, we explore the relevance of business ethics research for understanding the crucial role of business in (...) the dynamics of the Earth system. We do so by integrating the perspectives of business ethics and system-oriented sustainability science on the basis of the theory of metabolic rift, which explains how the dynamics of capitalism result in the destruction of the natural environment. On this basis, we argue that a mutually reinforcing relationship between perpetual economic growth and profit seeking behaviour of business, which we call the _loop of unsustainability_, continually deepens the metabolic rift and keeps business from effectively contributing to Earth system justice. This perspective allows us to formulate firm-level and system-level preconditions for attaining Earth system justice, and to sketch a research agenda that links business ethics scholarship with questions of Earth system justice.

Modularity is a fundamental doctrine in the cognitive sciences. It holds a preeminent position in cognitive psychology and generative linguistics, as well as a long history in neurophysiology, with roots going all the way back to the early nineteenth century. But a mature field of neuroscience is a comparatively recent phenomenon and has challenged orthodox conceptions of the modular mind. One way of accommodating modularity within the new framework suggested by these developments is to go for increasingly soft versions of (...) modularity. One such version, which I call the “system” view, is so soft that it promises to meet practically any challenge neuroscience can throw at it. In this paper, I reconsider afresh what we ought to regard as the sine qua non of modularity and offer a few arguments against the view that an insipid “system” module could be the legitimate successor of the traditional notion.

We develop an account of societal democratization that synthesizes cultural sociology and deliberative democracy. Cultural sociologists emphasize the symbolic inclusion of marginalized groups into the civil sphere. Deliberative democrats stress growth in the deliberative capacity of society. We argue that democratization entails the co-evolution of culture and reason. The basis of co-evolution is the performative construction of an inclusive demos, which requires a deliberative background but is also a source of the moral emotions that motivate deliberation. Since moral emotions can (...) also sweep people up and make them do reckless things, they must in turn be redeemable in inclusive deliberation. This synthesis sharpens a normative position for the evaluation of episodes of inclusion, extends current accounts of the place of emotion in cultural sociology and deliberative democracy, and provides a frame for comparative analyses of democratization. We illustrate with an examination of the exclusion and inclusion of Indigenous Australians. (shrink)

Research suggests that institutions affect the levels of corruption in a country. We take these arguments a step further and examine whether it is the presence of inclusive institutions and/or the credible and consistent implementation of institutions that matter, as regards corruption. We use a novel approach to theoretically conceptualise and empirically operationalise institutions along two analytically distinct dimensions: the nature of the institutions (the de jure dimension), and the extent to which they are credibly and consistently implemented over time (...) (the de facto dimension), using a panel dataset for 148 countries covering 2012 to 2018. We find that formal institutions are most effective in reducing corruption when the rules are credibly and consistently implemented. Furthermore, this effect appears to operate differently at different levels of national income. The nature of the formal institutions appears important across income levels, but particularly so at the upper middle income level, while the credible and consistent implementation of these institutions is primarily influential at upper middle income levels. We explain why this may be the case and elaborate on the policy implications. (shrink)

The essays in this volume blend historical and philosophical reflection with concern for contemporary political problems. They show that the causes and motivations of civil religion are a permanent fixture of the human condition, though some of its manifestations and proximate causes have shifted in an age of multiculturalism, religious toleration, and secularization.

Evidence of the pervasiveness of neural reuse in the human brain has forced a revision of the standard conception of modularity in the cognitive sciences. One persistent line of argument against such revision, however, cites the evidence of cognitive dissociations. While this article takes the dissociations seriously, it contends that the traditional modular account is not the best explanation. The key to the puzzle is neural redundancy. The article offers both a philosophical analysis of the relation between reuse and redundancy (...) as well as a plausible solution to the problem of dissociations. (shrink)

Is there a relation between the increasing extension of markets and market norms to previously non-market goods, and the growth of environmental problems? This chapter explores two competing answers: market-endorsing positions that argue that a source of environmental problems lies in the absence of markets in environmental goods and that the extension of markets or market modes of valuation to environmental goods offers the most effective way of protecting them; market-skeptical positions that deny that the extension of markets will protect (...) environmental goods or more strongly that markets and increasing marketization are themselves a source of environmental problems. These positions offer distinct perspectives on market mimicking instruments in environmental policy making, such as cost-benefit analysis, and on the development of new markets, for example in emission rights and biodiversity offsets. The issues raised include questions about value commensurability, justice, epistemic limits to planning and markets, and environmental limits to growth. (shrink)
