Using state-of-the-art observational datasets and results from a large archive of computer model simulations, a consortium of scientists from 12 different institutions has resolved a long-standing conundrum in climate science—the apparent discrepancy between simulated and observed temperature trends in the tropics. Research published by this group indicates that there is no fundamental discrepancy between modeled and observed tropical temperature trends when one accounts for: the uncertainties in observations; and the statistical uncertainties in estimating trends from observations. These results refute a (...) recent claim that model and observed tropical temperature trends “disagree to a statistically significant extent”. This claim was based on the application of a flawed statistical test and the use of older observational datasets. (shrink)

In this autobiographical essay, written in 2018 and previously unpublished, the late György Konrád intertwines his memories as a child during World War II with more theoretical reflections (and unanswered questions) on the war, its repercussions, its lessons. Written in Hungarian not long before his death in 2019, Konrád goes back in this essay to the period following the arrest of his parents after the German invasion of Hungary. Aged eleven, he was able to escape the small town where he (...) was born—and hence the fate of its entire Jewish community. “The others had been turned to ash,” in Konrád's chilling words. Seventy years later, he proceeds from these events to reflect on guilt and contrition, on sympathy and empathetic suffering, on how friends can become enemies during war, as well as on the Jewish heritage underlying Christian culture.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Possibility and Necessity in the Time of Peter Abelard by Irene BininiWolfgang LenzenIrene Binini. Possibility and Necessity in the Time of Peter Abelard. Investigating Medieval Philosophy Series. Leiden: Brill, 2021. Pp. xii + 326. Hardback, $166.00.This book is an impressive work written by a young Italian scholar who received her PhD only five years ago in Pisa. It is divided into three parts. Part 1 gives (...) a survey of "Early 12th-Century Debates on Modal Propositions"; part 2 is devoted to "Abelard's Modal Logic"; [End Page 327] part 3 deals with the views of "Abelard on the Metaphysics and Epistemology of Modalities." The author displays a profound knowledge of the relevant literature. The primary sources comprise twenty manuscripts preserved in various European libraries, plus forty-eight printed works (from Abelard to William of Sherwood). The list of secondary sources contains altogether 136 items from A (Astroh) to Z (Zagzebski), but, interestingly, it does not mention a monograph that, by its very title, claims to give an exposition of Abelard's logic, namely Maria Teresa Beonio-Brocchieri Fumagalli's La Logica di Abelardo (Firenze: La Nuova Italia, 1964).As far as I can judge (as a nonnative English-speaker), the linguistic quality of Binini's book is quite good. The explanations in the main text, including the translations from Latin sources, are easily comprehensible, and the many quotations (distributed over no less than 655 footnotes) are almost without any fault. Thus, the book rightly deserves inclusion in the prestigious series Investigating Medieval Philosophy. Yet, at least according to my taste, the book contains many redundancies. Again and again, the author first explains a certain issue at some length, then confirms the correctness of her interpretation by means of a longer (English) quotation, and finally reconfirms it by fully quoting the Latin text in the footnotes.As Binini explains in the book's concluding chapter, her aim is to present "an all-encompassing reflection on [Abelard's] works on modalities" and "a comparison between these works and the parallel reflections advanced by other masters and logicians in the early 12th century" (308). She undoubtedly achieves this goal. The comparison of Abelard's views on possibility and necessity with the views of other logicians is mainly carried out in chapters 1–3. Ancient and early medieval logicians such as, in particular, the Stoics and Boethius favored the basic idea that "something," p, is necessary if and only if p is always the case (or true). Accordingly, p is possible if and only if p is at least sometime the case. Abelard, however, was not willing to accept that each possibility has to become realized at some time. He instead offered a "nature-based characterization of possibility" that can "account for unrealized, past, counterfactual, and even unactualizable possibilities" (308). Abelard's idea is that something, x, is possibly a P if and only if the property of being P is compatible with the nature of x. Hence this view basically amounts to a de re conception of possibility that attributes modalities to things, while the temporal view attributes modal properties primarily to propositions (or states of affairs) and hence can be labeled de dicto (or de sensu).Let us now turn to Binini's twofold aim (as formulated on the back cover of her book) to present a "uniform and consistent" reassessment of Abelard's theory of modalities and of his modal logic. The former task is tackled in chapters 8–10. After summarizing, in chapter 8, Abelard's general views on "Nature and Modalities," chapter 9 is devoted to a detailed discussion of the "Many Senses of Possibility." In five consecutive sections, Binini investigates the conception of (1) possibility as "non-repugnancy with nature" (illustrated by the thesis that "any man can be a bishop" [235]); (2) unrealizable but "conceivable" possibilities (such as the existence of humans lacking the ability to laugh [240]); (3) determinate potencies (like that of an amputee who nevertheless "can walk" [248]); (4) past and counterfactual potencies (like that of a blind person who might be able to see); and (5) other puzzling de re possibilities (such as "irrational humans" [261]).The final...

After the Second World War, a renaissance in field primatology took place in the United States under the aegis of the ‘new physical anthropology’. Its leader, Sherwood Washburn, envisioned a science uniting studies of hominid fossils with Darwinian population genetics, experimental functional anatomy, and field observation of non-human primates and human hunter–gatherers. Thanks to Washburn’s stimulus, his colleague at Berkeley, the bird ethologist Peter Marler, took up the study of the natural communicative behaviour of apes and monkeys. When (...) Marler’s first primatological student, Thomas Struhsaker, reported in the mid-1960s that the vervet monkeys of Amboseli, Kenya, give acoustically distinct alarm calls to different predators, and respond to alarm calls as if to the sight of those predators, a debate broke out over whether the vervet calls thus function as names, translating as ‘leopard’, ‘eagle’ and ‘python’. Washburn and his students argued that no matter what the behavioural evidence, vervet calls could not be predator names, since monkeys had been shown to lack the neuroanatomical basis of naming. This controversy thus reveals, first, the persistence of older patterns of disciplinary allegiance within the new, synthetic physical anthropology; and second, the impotence of adaptationist Darwinism — common to both sides of the debate — as a force for unity.

Since logic in the 13th century is focussed on syllogistics as its main subject, textbooks on logic provide us with large and detailed treatments of the proposition as the immediate and constitutive basis of the syllogism. In the present paper I will give a survey of these treatments and pay special attention to a certain side-issue, namely to non-assertive sentences and to some difficulties concerning their classification. I will focus on William of Sherwood's apporach to the subject and compare (...) it with the conceptions of Roger Bacon, Peter of Spain and Lambert of Lagny, who are the auhtors of the three main logic compendia besides William of Sherwood's in the thirteenth century.

The thirteenth-century logician Lambert of Auxerre was well known for his Summa Lamberti, or simply Logica, written in the mid-1250s, which became an authoritative textbook on logic in the Western tradition. Our knowledge of medieval logic comes in great part from Lambert's Logica and three other texts: William of Sherwood's Introductiones in logicam, Peter of Spain's Tractatus, and Roger Bacon's Summulae dialectics. Of the four, Lambert's work is the best example of question-summas that proceed principally by asking and (...) answering questions on the subject matter. Thomas S. Maloney's translation of Logica, the only complete translation of this work in any language, is a milestone in the study of medieval logic. More than simply a translation, Maloney's project is a critical, comprehensive study of Lambert's logic situated in the context of his contemporaries and predecessors. As such, it offers a wealth of annotation and commentary. The lengthy introduction and extensive notes to the text explain the origin, theoretical context, and intricacies of the text and its doctrines. Maloney also addresses the disputed issues of authorship, date, and place of publication of the Summa Lamberti and makes available to the English-only audience the French, German, and Italian secondary sources--all translated--that are needed to enter the discussion. "Thomas S. Maloney fully commands the primary and secondary sources necessary to elucidate Lambert's Logica. An expert on Roger Bacon's philosophy, he demonstrates a rare proficiency in medieval Latin and scholastic logic. His references to sources from the ancient (Aristotle and Boethius) and medieval worlds are apposite, perspicuous, and useful. The volume's presentation with an appropriate introduction and commentary in the endnotes will no doubt establish it as an indispensable resource for scholars in the twenty-first century." --Alan Perreiah, University of Kentucky.

_ Source: _Volume 56, Issue 3-4, pp 320 - 339 Thirteenth-century views on consequences have not yet received much attention. Authors of this period deserve closer scrutiny, because of their profound interest in the nature of consequence. The fundamental feature of a consequence was captured in the claim that its antecedent is the cause of its consequent. At the same time authors systematically discussed consequences in terms of truth-preservation. This paper considers the requirements of syllogistic argument and consequences in general, (...) including the role of ‘cause’ in the identification of syllogisms proper, looks at different descriptions of consequence, moves on to discussions of the syncategorema ‘_si_’ – in _syncategoremata_ treatises by Peter of Spain, Henry of Ghent, Nicholas of Paris and William of Sherwood, as well as some _sophismata_ tracts – and explores what thirteenth-century authors make of the truth-functional characterisation of consequence, showing how it clashes with the authors’ insistence on a causal connection between antecedent and consequent.

Armstrong holds the Supervenience Theory of instantiation, namely that the instantiation of universals by particulars supervenes upon what particulars and what universals there are, where supervenience is stipulated to be explanatory or dependent supervenience. I begin by rejecting the Supervenience Theory of instantiation. Having done so it is then tempting to take instantiation as primitive. This has, however, an awkward consequence, undermining one of the main advantages universals have over tropes. So I examine another account hinted at by Armstrong. This (...) is the Operator Theory of instantiation, by which I mean the theory that universals are operators, and that a particular instantiates a monadic universal because the universal operates on the particular, resulting in the state of affairs. On this theory the state of affairs supervenes on the instantiation rather than vice versa. In the second part of the paper I develop this theory of universals as operators, including an account of structural universals, which are useful for accounts of modality and of mathematics.

In this major study, Peter Zarrow examines how textbooks published for the Chinese school system played a major role in shaping new social, cultural, and political trends, the ways in which schools conveyed traditional and 'new style' knowledge and how they sought to socialize students in a rapidly changing society in the first decades of the twentieth century. Focusing on language, morality and civics, history, and geography, Zarrow shows that textbooks were quick to reflect the changing views of Chinese (...) elites during this period. Officials and educators wanted children to understand the physical and human worlds, including the evolution of society, the institutions of the economy, and the foundations of the nation-state. Through textbooks, Chinese elites sought ways to link these abstractions to the concrete lives of children, conveying a variety of interpretations of enlightenment, citizenship, and nationalism that would shape a generation as modern citizens of a new China.

In The Geographer′s Art, Peter Haggett expounds his view of the nature and purpose, philosophy and methodology of the discipline and practice of geography. Ranging over every aspect of the subject, he considers the attractions, opportunities and responsibilities of life as a geographer and tries to answer some of the basic questions facing the discipline. The result is a highly individual look at geography and geographers, illustrated throughout from his own research and experience. Geography is immemorial and universal: it (...) touches us in many ways, in many forms and frequently in a manner neither fully perceived nor understood. Today interest in geography is booming: both the need for greater geographic awareness and the geographer′s vital role in understanding the processes and consequences of global and environmental change have received widespread recognition throughout the world. Yet the nature of the subject and the role of geographers remain little known to non–geographers and have yet to penetrate many hallowed academic and government halls. Just what do geographers do? What fires their imagination? Why are they so devoted to their subject? How can geography be used? Do we need more or less geographers, and how should they be educated? These and many other issues are addressed by Peter Haggett as he ranges over every aspect of the subject, theoretical and applied, physical and human, in order to explain the essence and importance of this multi–faceted subject. Few books can have conveyed so convincingly and so vividly the intellectual challenge of working in the field and the vital relevance of the discipline to contemporary human and environmental problems.

In this account of his mature thinking, Peter Marshall develops a dynamic and organic philosophy for the coming millennium which he calls liberation ecology. Liberation ecology is holistic in viewing the world as a harmonious whole and all beings and things as interwoven threads in nature's web. It is intuitive in recognizing intuition as the main source of knowledge and the imagination as the great organ of morality. It is ecological in seeing human beings as fellow voyagers with other (...) species in the magnificent odyssey of evolution. Above all, it is libertarian in seeking to release humanity, society and nature from their existing burdens so that they can unfurl and realize together their full potential. Exploring our strengths and possibilities, this book presents the ideas and values needed to ride the winds of change at this crucial stage in our development and in the history of the world. It provides a new philosophy for a new era, an uplifting and inspired vision which combines ancient wisdom and modern insights, reason and feeling, science and poetry, myth and the marvellous. It offers a guide for the future on how to rive in the most fulfilling way and how to create a genuinely free and sustainable society in harmony with nature. (shrink)

This paper is about the development of logic in the Aristotelian tradition, from Aristotle to the mid-fourteenth century. I will compare four systems of logic with regard to their expressive power. 1. Aristotle’s own logic, based mostly on chapters 1-2 and 4-7 of his Prior Analytics 2. An expanded version of Aristotle’s logic that one finds, e.g., in Sherwood’s Introduction to Logic and Peter of Spain’s Tractatus 3-5. Versions of the logic of later supposition theorists such as William (...) Ockham, John Buridan, and Paul of Venice. Version 4 is the logic without relatives ; version 5 adds relatives. I am ignoring modals, conditionals that are not ut nunc, infinitizing negation, exclusives and exceptives, all exponibles, all insolubles, and terms with simple or material supposition, ampliation and restriction, and many other things.

An introduction to Rousseau's Confessions.

Although generally philosophers have put a high valuation on reason, increasingly the role of emotions in motivating action is being recognized. The essays in this volume explore the emotions from a variety of perspectives, ranging from Aristotelian views of the passions to the new findings of cognitive science, and from such diverse starting points as medieval literature and psychological studies.

Reflecting on the pursuit of knowledge and wisdom in higher education, this insightful treatise considers the roots and philosophical underpinnings of the university education as the path to mindful living. Peter Milward shares his sage thoughts on a wide range of subjects, including philosophy, science, nature, art, religion, and finding one's place in the world. Thought-provoking and uplifting, Wisdom and the Well-Rounded Life is an excellent foundation for anyone seeking a well-rounded education and an enriching life.

I argue in this paper that moral philosophers need to incorporate into their teaching and writing a number of empirical findings on ethical practices. Principal among these is clearer guidelines on speaking out against wrongdoing, as well as the development of codes of ethics that have been proven to work. The adoption of the critical thinking and the analytical methodology of other disciplines is also suggested. Several benefits will result. The most noticeable will be a strengthening of ethical practices and (...) behavior in the institutions and organizations with which we live and work. A second benefit will be the education and employment of a body of people—graduates in moral philosophy—with the skills and knowledge to bring about, and further strengthen, this enhanced ethical environment. A third benefit will be the matching of the claims of philosophical thought with actual reality. (shrink)

Rawls's difference principle, according to which social and economic inequalities are justified only if they achieve the greatest benefit of the least advantaged, has been often interpreted as a maximin-principle, in order to make it fit into the frame of welfare economics. Under this interpretation, however, the difference principle is subject to such grave objections, that it can hardly serve as a principle of justice. In order to avoid these difficulties, modifications of the difference principle have been proposed by Sen (...) and Rae. But these proposals don't lead to acceptable resolutions either. As an alternative, a new interpretation of Rawls's difference principle is proposed, which brings out the reasonable core of this principle and, at the same time, repairs the shortcomings of its earlier interpretations.
