Scaliger brought critical standards and methodological innovations to the already extensive sixteenth-century interest in chronology. He invented the Julian Period, a device for the reckoning of dates, exposed historical forgeries, and showed the independent value of non-Biblical sources even acknowledging Egyptian dynastic chronology antedating the Biblical Creation, although he could not satisfactorily resolve this conflict. After Scaliger, the quality of chronological studies declined as questions were argued less on historical grounds than on theological ones, but the confusion this created eventually (...) contributed to breaking the hold of the Bible on chronology, along the lines anticipated by Scaliger.

This paper focuses on chronology, structure and purpose of Dirck Canter’s edition of comic fragmentary poets, Aristophanes and Menander in mss. Par. suppl. gr. 1013 and D’Orville 123. It studies the history of the texts and offers unpublished conjectures of Dirck Canter and Joseph Justus Scaliger to the text of the comic poets and Machon’s “Chreiai”.

Around 1716, the French astronomer and academician Joseph-Nicolas Delisle took up a new project: the twinned topics of Chinese chronology and astronomy. Unable to access Chinese sources and not knowing any fellow savants who shared this particular interest, Delisle methodically made extracts and compiled data from the existing European literature. Among Delisle's papers at the Observatoire de Paris still exist the results of this research, including a list of the books he found relevant. This paper develops a close reading (...) of Delisle's notes from this period to stage his journey into a recondite arena of technical and textual analysis, and to examine the scholarly practices and generic conventions through which early modern European savants confronted the Chinese astronomical tradition.

After introducing the new field of cultural evolution, we review a growing body of empirical evidence suggesting that culture shapes what people attend to, perceive and remember as well as how they think, feel and reason. Focusing on perception, spatial navigation, mentalizing, thinking styles, reasoning (epistemic norms) and language, we discuss not only important variation in these domains, but emphasize that most researchers (including philosophers) and research participants are psychologically peculiar within a global and historical context. This rising tide of (...) evidence recommends caution in relying on one’s intuitions or even in generalizing from reliable psychological findings to the species, Homo sapiens. Our evolutionary approach suggests that humans have evolved a suite of reliably developing cognitive abilities that adapt our minds, information-processing abilities and emotions ontogenetically to the diverse culturally-constructed worlds we confront.

This book critically assesses arguments for the existence of the God of classical theism, develops an innovative account of objects’ persistence, and defends new arguments against classical theism. The authors engage the following classical theistic proofs: Aquinas’s First Way, Aquinas’s De Ente argument, and Feser’s Aristotelian, Neo-Platonic, Augustinian, Thomistic, and Rationalist proofs. The authors also provide the first systematic treatment of the ‘existential inertia thesis’. By connecting the thesis to relativity theory and recent developments in the philosophy of physics, and (...) by developing a variety of novel existential-inertia-friendly explanations of persistence, they mount a formidable new case against classical theistic proofs. Finally, they defend new arguments against classical theism based on abstract objects and changing divine knowledge. The text appeals to students, researchers, and others interested in classical theistic proofs, the existence and nature of God, and the ultimate explanations of persistence, change, and contingency.

There is an idea, extremely common among social contract theorists, that the primary function of social institutions is to secure some form of cooperative benefit. If individuals simply seek to satisfy their own preferences in a narrowly instrumental fashion, they will find themselves embroiled in collective action problems – interactions with an outcome that is worse for everyone involved than some other possible outcome. Thus they have reason to accept some form of constraint over their conduct, in order to achieve (...) this superior, but out-of-equilibrium outcome. A social institution can be defined as a set of norms that codify these constraints.1 Simplifying somewhat, one can then say that social institutions exist in order to secure gains in Pareto-efficiency.

While engaging in rich discussion, Conspiracy Theories analyzes current arguments and evidence while providing real-world examples so students can contextualize and visualize the debates. Each chapter addresses important current questions, provides conceptual tools, defines important terms, and introduces the appropriate methods of analysis.

The term 'implicit bias' has very swiftly been incorporated into philosophical discourse. Our aim in this paper is to scrutinise the phenomena that fall under the rubric of implicit bias. The term is often used in a rather broad sense, to capture a range of implicit social cognitions, and this is useful for some purposes. However, we here articulate some of the important differences between phenomena identified as instances of implicit bias. We caution against ignoring these differences: it is likely (...) they have considerable significance, not least for the sorts of normative recommendations being made concerning how to mitigate the bad effects of implicit bias.

Historical chronology is the discipline that establishes the dates of events and reconstructs the calendars used in ancient, medieval, and early modern times. Traditional accounts state that Joseph Scaliger (1540-1609) created this field by combining philological with astronomical data and techniques. But the celestial phenomena most relevant to chronology are solar and lunar eclipses. From antiquity onwards, astrologers saw these as ominous and connected them to great events on earth. Though Scaliger used dated eclipses in his work, it was (...) a number of relatively obscure sixteenth-century astronomers and scholars who realized that one could date events by eclipses and began doing so in a systematic way, without assigning them any ominous force.

Karl Popper’s “Indeterminism in Quantum Physics and in Classical Physics” suffers unjust neglect. He judged determinism false: the future is open. In principle, replacing Laplace's variant of predetermination with predictable predetermination renders “scientific” determinism scientific and so refutable. Popper claimed that he had refuted it. Now a metaphysical system may have an extension—in the mathematical sense—that may render it explanatory and testable. If it exists, then it is not unique but has many alternative extensions. Popper’s proof is then inconclusive.

In lieu of an abstract, here is a brief excerpt of the content:Cocceius and the Jewish CommentatorsAdina M. YoffieThe case of Johannes Cocceius defies the commonplace that Leiden University (and perhaps post-Reformation, confessionalized Europe in general) turned away from humanist scholarship in the first quarter of the seventeenth century. In 1650 Cocceius (1603-69), a Bremen-born Oriental philology professor at Franeker, joined the Leiden theological faculty and wrote a treatise, Protheoria de ratione interpretandi sive introductio in philologiam sacram (De ratione). He (...) praised such rabbinic exegetes as Rashi (1040-1105) and David Kimchi (ca. 1160-ca. 1235) in humanist terms for their erudition. At the same time the "new" Cartesian philosophy was taking hold in the arts faculty, and mathematics instruction was encroaching on scholastic formal logic.1 Leiden would become famous for Cartesianism, mathematics, and "Calvinist Copernicanism" in the second half of the seventeenth century, but Cocceius still worked in the tradition of advanced humanist scholarship that had made the institution famous in the sixteenth century.2Leiden's earlier reputation was due in large part to the biblical humanist work of such Renaissance polymaths as Joseph Justus Scaliger (1540-1609) and Hugo Grotius (1583-1645), but by Cocceius's time Leiden theologians were subject to greater Church and State control. As Jonathan Israel and Edwin Rabbie have shown, in response to the controversy that surrounded Jacobus Arminius and his stand on predestination, the Synod of Dordrecht (Dort) drafted an anti-Arminian statement in 1619; any professor who did not sign was subject [End Page 383] to exile from the republic in addition to dismissal from his post.3 Innovative theology, exegesis, and philology suffered as professors, fearing State and Church reprisals, turned to "dogmatic humanism." As Henk Jan de Jonge has explained, this meant that "almost all the theologians of seventeenth-century Leiden who concerned themselves with the explanation of the New Testament placed exegesis at the service of dogmatic objectives."4 Unlike his fellow Leiden theologians, Cocceius pursued biblical humanism and Christian Hebraism through the study of Hebrew, Greek, and Aramaic-and he did so in a unique way. He was not the first to use Jewish commentaries and even Jewish post-biblical literature for the purpose of reconstructing the original Hebrew Bible, but he was innovative in praising rabbinic scholars as fellow humanists and in incorporating their scholarship into his Christological exegesis and philosophy. He did so, furthermore, not as an independent scholar or pastor or even as a professor of Hebrew; but as the holder of a university chair in theology at a confessionalized university in a century hostile to his brand of late humanism.Although he came to Leiden as a theologian, Cocceius had impressive training as an Orientalist. He had studied with the famous scholar Sixtinus Amama (1593-1629) and polished his Hebrew and Aramaic by working with a Jewish tutor from Hamburg.5 While still a student at Franeker, Cocceius wrote a translation and commentary of the Talmudic tractate Sanhedrin. A few years later he began composing commentaries on the Pentateuch, and, by the time he arrived at Leiden, he had completed one lecture, series of lectures, or piece of writing on every book of the Old Testament. These commentaries were based not only on Cocceius's extensive knowledge of Oriental languages but also on his readings of medieval Jewish commentators. These were the same commentators that Cocceius would later praise in chapter eight of the De ratione.These humanist achievements were much at variance with Cocceius's public persona as perhaps the most prominent Dutch Calvinist theologian of the seventeenth century. For approximately 100 years after his death in 1669 a faction of Leiden theologians calling themselves "Cocceians" battled the "Voetians," followers of Gisbertus Voetius, for the soul of the Dutch Church.6 At Leiden he lectured on the Pauline Epistles, a typical subject for a seventeenth-century Calvinist theologian, and he worked on his famous theological tract, the salvation-historical Summa doctrinae de foedere et testamento Dei (1648). Neither the De ratione nor his voluminous biblical commentary (except [End Page 384] for a short treatise on the last six chapters of Deuteronomy) was published in Cocceius's lifetime. His son Johann Heinrich released these and his father's... (shrink)

Socrates’ official answer to Meno’s question about the value of knowledge, near the end of Plato’s Meno, is that knowledge is stable. I argue that both the answer and the question have been widely misunderstood. The question has been taken to be why knowing at a time is better than true belief at that time, and Socrates’ answer has been taken to point to the greater persistence of knowledge over time. I argue instead that, given the broader context of the (...) question and answer in the Meno, together with what Plato has to say about stability elsewhere, Meno’s question is better understood as a more difficult question – and Socrates’ answer as a good solution to it. This also involves arguing that Socrates’ analogy to the statues of Daedalus is not intended as the simple illustration of Socrates’ official answer for which commentators have taken it. (shrink)

Since the very beginning, Confucianism has been troubled by a serious gap between its political ideals and the reality of societal circumstances. Contemporary Confucians must develop a viable method of governance that can retain the spirit of the Confucian ideal while tackling problems arising from nonideal modern situations. The best way to meet this challenge, Joseph Chan argues, is to adopt liberal democratic institutions that are shaped by the Confucian conception of the good rather than the liberal conception of (...) the right.Confucian Perfectionism examines and reconstructs both Confucian political thought and liberal democratic institutions, blending them to form a new Confucian political philosophy. Chan decouples liberal democratic institutions from their popular liberal philosophical foundations in fundamental moral rights, such as popular sovereignty, political equality, and individual sovereignty. Instead, he grounds them on Confucian principles and redefines their roles and functions, thus mixing Confucianism with liberal democratic institutions in a way that strengthens both. Then he explores the implications of this new yet traditional political philosophy for fundamental issues in modern politics, including authority, democracy, human rights, civil liberties, and social justice.Confucian Perfectionism critically reconfigures the Confucian political philosophy of the classical period for the contemporary era.

Benardete paradoxes involve a beginningless set each member of which satisfies some predicate just in case no earlier member satisfies it. Such paradoxes have been wielded on behalf of arguments for the impossibility of an infinite past. These arguments often deploy patchwork principles in support of their key linking premise. Here I argue that patchwork principles fail to justify this key premise.

In this impressive first book, Clark explores the extraordinary history of the Destruction of Troy by Dares the Phrygian. Dares's account of the fall of Troy is a short, Latin prose narrative that claims to be an eyewitness account of the Trojan War, translated from the Phrygian by Cornelius Nepos, the Roman historian, and sent to Sallust, another, even more famous Roman historian. Dares's text came to light as late antiquity turned into the medieval era, and Dares was promptly hailed (...) as “the first pagan historian”—a predecessor of Homer—by Isidore of Seville. Throughout the medieval period, a series of scholars were transfixed by Dares. His text was taken as the earliest and thus most reliable source for the world-changing event of the Trojan War—which led to the foundation of Rome and the shape of the West. It was exciting not just for its antiquity but also for its polemical revision of the standard received story. Not only did its prefatory letter claim—with a nicely rationalizing rhetoric—that even the Athenians declared Homer was “insane” for imagining that gods and humans might meet on the battlefield, but also, even more alluringly, Dares stated that Aeneas, the pious hero of Virgil's Aeneid, was a traitor who had sold out Troy to the Greeks: he escaped the sack to found Rome because he had opened the doors of the city to its enemies. The pious Aeneas, exemplary hero, committed the deeply impious act of treachery to his own fatherland. Dares provided a moral rejoinder to later Roman political propaganda and provoked a set of intense debates about the past, its value, and its truth.Early modern humanists were more suspicious. The great scholars Scaliger and Vossius in particular turned their philological fervor against what they saw as an obvious forgery—but even then, not everyone was persuaded. The celebrated Bodin, most surprisingly, still thought Dares represented historical truth. Clark carefully shows how oversimplified the common story of the triumph of humanist learning is. It took a lot of work and much forgetting as well as persuasion for Dares to lose his position. It was indeed only in the Enlightenment that Dares finally passed into the half-light of insignificance reserved for forgeries. One strength of Clark's book is his insistence on trying to discover with generosity and understanding how apparently baffling opinions could be held and argued for—how, that is, the past is a foreign country even and especially where such apparently basic ideas as historical truth are at stake (a topic not without relevance in modern politics).Clark examines in considerable detail across several centuries how Dares was read and mobilized. It is especially satisfying to have a work of reception history that stretches across the modern historiographical divides (of the late antique, medieval, early modern, and Enlightenment periods) and sees how complex the lines of continuity and change are. The naive prose of Dares, in Clark's sophisticated analysis, raises profound questions of what antiquity is and why it matters; how authenticity and authorship are constructed differently across this time period; what the relations are between fiction, truth, and exemplarity (both in theory and in practice); and how texts shift in status and attribution. Dares indeed, as Clark puts it well, “test[s] the meaning and boundaries of antiquity itself.” The range of material is stunning: not only in terms of who read and used Dares but also in terms of the other texts that were read and transformed alongside his. It is remarkable, for example, to see how Joseph of Exeter's medieval hexameters were attributed to Dares (and then reattributed), or how Dares became silently incorporated into a work of Jerome. Despite this richness, I would have liked to see more pages on the relation between pagan and Christian historiography. How does Dares's believed (but false) claim to be an eyewitness relate to Christian claims to witness events (martyr means [eye-]witness)? Philology and its attack on authenticity were key to the battles of the Reformation. Clark could also have spent more time exploring what difference the rediscovery of the Greek text of Homer made to the story of Dares's reception. Homer's rise in the West is part of Dares's fall. In its detail, however, and its range of questions and scope of material, The First Pagan Historian is an exemplary work of reception history. (shrink)

Technical chronology establishes the structure of calendars and the dates of events; it is, as it were, the foundation of history, particularly ancient history. The chronologer must know enough philology to interpret texts and enough astronomy to compute the dates of celestial phenomena, above all eclipses, which alone provide absolute dates. Joseph Scaliger, so we are told, was the first to master and apply this range of technical skills: Of the mathematical principles on which the calculation of periods rests, (...) the philologians understood nothing. The astronomers, on their side, had not yet undertaken to apply their data to the records of ancient times. Scaliger was the first of the philologians who made use of the improved astronomy of the sixteenth century to get a scientific basis for historical chronology. So Mark Pattison. This verdict can be challenged on a number of grounds. The one relevant at present is simple: Scaliger himself claimed far less. He certainly said that technical chronology had been untouched in modern times — not an entirely fair judgement — but in antiquity it had been practised in exactly the manner he considered proper, or so he believed. In particular he singles out Censorinus, whose De die natali drew extensively on Varro's lost Antiquitates rerum humanarum, books 14–19, for information on chronology. Students of Varro have long appreciated the importance of Censorinus. His dry and compact treatise offers Varronian views on etymology, the human life-span, and the course of history itself, all couched in language so jejune as to suggest that he added little or nothing to what he read.

Summarizing this century's major debates over realism and the rationality of scientific knowledge, Joseph Rouse believes that these disputes oversimplify the ...

Naturalism as a guiding philosophy for modern science both disavows any appeal to the supernatural or anything else transcendent to nature, and repudiates any philosophical or religious authority over the workings and conclusions of the sciences. A longstanding paradox within naturalism, however, has been the status of scientific knowledge itself, which seems, at first glance, to be something that transcends and is therefore impossible to conceptualize within scientific naturalism itself. In Articulating the World, Joseph Rouse argues that the most (...) pressing challenge for advocates of naturalism today is precisely this: to understand how to make sense of a scientific conception of nature as itself part of nature, scientifically understood. Drawing upon recent developments in evolutionary biology and the philosophy of science, Rouse defends naturalism in response to this challenge by revising both how we understand our scientific conception of the world and how we situate ourselves within it.

This text provides an extensive exploration of the relationship between the thought of Otto Neurath and Rudolf Carnap, providing a new argument for the complementarity of their mature philosophies as part of a collaborative metatheory of science. In arguing that both Neurath and Carnap must be interpreted as proponents of epistemological naturalism, and that their naturalisms rest on shared philosophical ground, it is also demonstrated that the boundaries and possibilities for epistemological naturalism are not as restrictive as Quinean orthodoxy has (...) previously suggested. Both building on and challenging the scholarship of the past four decades, this naturalist reading of Carnap also provides a new interpretation of Carnap’s conception of analyticity, allowing for a refutation of the Quinean argument for the incompatibility of naturalism and the analytic/synthetic distinction. In doing so, the relevance and potential importance of their scientific meta-theory for contemporary questions in the philosophy of science is demonstrated. This text appeals to students and researchers working on Logical Empiricism, Quine, the history of analytic philosophy and the history of philosophy of science, as well as proponents of naturalized epistemology.

This essay takes issue with Alasdair MacIntyre’s denial that teaching is a practice. It does so less by appeal to MacIntyre’s concept of practice than by criticism of his conception of teaching. It argues that this conception, as reconstructed from adversions to teaching in a range of his writings, does less than justice to what good teachers accomplish; and that, if this inadequacy is rectified—as much else in his writings suggests that it ought to be—there are clearer grounds for acknowledging (...) teaching as a practice.

Olof Rudbeck’s Atlantica is a characteristically wide-ranging example of Early Modern scholarship in which the author draws on a compendious assortment of evidence to argue that his native Sweden was the cradle of human civilization. Within this discussion, he devotes particular attention to the Phoenicians, whom he attempts to paint as descendants of “Scythians” who had migrated to the Mediterranean from an original Swedish homeland. Drawing upon the work of earlier Phoenician scholars such as Joseph Scaliger and Samuel Bochart, (...) as well as his own, often rather creative, etymologies, he seeks to demonstrate a relationship between the Phoenician language and Swedish. This paper explores how Rudbeck engages with and utilizes the Phoenician people and the Phoenician language in service of his wider proto-nationalist goals and places his work within the wider context of Phoenician studies in Early Modern Europe, a few decades before Barthélemy’s decipherment of the Phoenician script. While clearly wrong in many of his conclusions, Rudbeck’s work can tell us much about perceptions of Phoenicians at an important time of transition between Renaissance scholarship and the beginnings of modern archaeological and linguistic research.

What does it mean to assert or deny the existence of a legal system? How can one determine whether a given law belongs to a certain legal system? What kind of structure do these systems have, that is--what necessary relations obtain between their laws? The examination of these problems in this volume leads to a new approach to traditional jurisprudential question, though the conclusions are based on a critical appraisal, particularly those of Bentham, Austin, Kelsen, and Hart.

In the economic literature on the firm, especially in the transaction–cost tradition, a sharp distinction is drawn between so-called “market transactions” and “administered transactions.” This distinction is of enormous importance for business ethics, since market transactions are governed by the competitive logic of the market, whereas administered transactions are subject to the cooperative norms that govern collective action in a bureaucracy. The widespread failure to distinguish between these two types of transactions, and thus to distinguish between adversarial and non-adversarial relations, (...) has led many business ethicists to develop a “uniform” moral code. Yet in market transactions, the checks and balances built into the system of commercial exchange are such as to permit more instrumental forms of behavior. In administered transactions, by contrast, these checks and balances are absent, and thus the institutional context calls for much greater exercise of moral restraint. In this paper, I begin the task of developing an adversarial ethic for business. According to this view, the competitive environment licenses a greater range of “self-interested” behavior, but also imposes its own constraints on the strategies that firms may adopt in the pursuit of their interests.

Biomedical engineering technologies such as brain–machine interfaces and neuroprosthetics are advancements which assist human beings in varied ways. There are exciting yet speculative visions of how the neurosciences and bioengineering may influence human nature. However, these could be preparing a possible pathway towards an enhanced and even posthuman future. This article seeks to investigate several ethical themes and wider questions of enhancement, transhumanism and posthumanism. Four themes of interest are: autonomy, identity, futures, and community. Three larger questions can be asked: (...) will everyone be enhanced? Will we be “human” if we are not, one day, transhuman? Should we be enhanced or not? The article proceeds by concentrating on a widespread and sometimes controversial application: the cochlear implant, an auditory prosthesis implanted into Deaf patients. Cochlear implantation and its reception in both the deaf and hearing communities have a distinctive moral discourse, which can offer surprising insights. The paper begins with several points about the enhancement of human beings, transhumanism’s reach beyond the human, and posthuman aspirations. Next it focuses on cochlear implants on two sides. Firstly, a shorter consideration of what technologies may do to humans in a transhumanist world. Secondly, a deeper analysis of cochlear implantation’s unique socio-political movement, its ethical explanations and cultural experiences linked with pediatric cochlear implantation—and how those wary of being thrust towards posthumanism could marshal such ideas by analogy. As transhumanism approaches, the issues and questions merit continuing intense analysis. (shrink)

One of the most influential ideas in the field of business ethics has been the suggestion that ethical conduct in a business contextshould be analyzed in terms of a set of fiduciary obligations toward various “stakeholder” groups. Moral problems, according to this view, involve reconciling such obligations in cases where stakeholder groups have conflicting interests. The question posed in this paper is whether the stakeholder paradigm represents the most fruitful way of articulating the moral problems that arise in business. By (...) way of contrast, I outline two other possible approaches to business ethics: one, a more minimal conception, anchored in the notion of a fiduciary obligation toward shareholders; and the other, a broader conception, focused on the concept of market failure. I then argue that the latter offers a more satisfactory framework for the articulation of the social responsibilities of business. (shrink)

We examine two competing solutions to Benardete paradoxes: causal finitism, according to which nothing can have infinitely many causes, and the unsatisfiable pair diagnosis (UPD), according to which such paradoxes are logically impossible and no metaphysical thesis need be adopted to avoid them. We argue that the UPD enjoys notable theoretical advantages over causal finitism. Causal finitists, however, have levelled two main objections to the UPD. First, they urge that the UPD requires positing a ‘mysterious force’ that prevents paradoxes from (...) arising. Since such a force is implausible, the UPD is in trouble. Second, they employ recombination or patchwork principles to argue that paradoxical situations would be possible if causal finitism were false. Since such situations are not possible, causal finitism is true, and so a substantive metaphysical thesis is needed to avoid the paradoxes. We argue that the UPD proponent can successfully respond to these objections. (shrink)
