Concerns about the welfare of agricultural animals in corporate or “factory farming” systems are growing. Increasingly, it is suggested that modem farm animal production practices are morally objectionable, causing physical and mental suffering to animals. Such criticisms are premised on beliefs about the mental capacities of farm animals that are not wholly supported by scientific evidence, for little is known about farm animal cognition. Some animal scientists, realizing that concerns about the treatment of agricultural animals cannot be addressed in absence (...) of knowledge about farm animal mentality, have begun cognitive studies of farm animals. Subsequently, several ethical problems have emerged. In this paper it is argued that while farm animal cognition studies are needed, scientists must consider the moral problems and implications of the research, and must devise empirically testable hypotheses about those aspects of cognitive behavior that are relevant to discussions about moral treatment of farm animals.

Pancreatitis is a complex, progressively destructive inflammatory disorder. Alcohol was long thought to be the primary causative agent, but genetic contributions have been of interest since the discovery that rare PRSS1, CFTR and SPINK1 variants were associated with pancreatitis risk. We now report two associations at genome-wide significance identified and replicated at PRSS1-PRSS2 and X-linked CLDN2 through a two-stage genome-wide study. The PRSS1 variant likely affects disease susceptibility by altering expression of the primary trypsinogen gene. The CLDN2 risk allele is (...) associated with atypical localization of claudin-2 in pancreatic acinar cells. The homozygous CLDN2 genotype confers the greatest risk, and its alleles interact with alcohol consumption to amplify risk. These results could partially explain the high frequency of alcohol-related pancreatitis in men. © 2012 Nature America, Inc. All rights reserved. (shrink)

The _Analects_ is a compendium of the sayings of Confucius (551-479 b.c.e.), transcribed and passed down by his disciples. How it came to be transformed by Zhu Xi (1130-1200) into one of the most philosophically significant texts in the Confucian tradition is the subject of this book. Scholarly attention in China had long been devoted to the _Analects._ By the time of Zhu Xi, a rich history of commentary had grown up around it. But Zhu, claiming that the _Analects_ was (...) one of the authoritative texts in the canon and should be read before all others, gave it a still more privileged status in the tradition. He spent decades preparing an extended interlinear commentary on it. Sustained by a newer, more elaborate language of metaphysics, Zhu's commentary on the _Analects_ marked a significant shift in the philosophical orientation of Confucianism--a shift that redefined the Confucian tradition for the next eight centuries, not only in China, but in Japan and Korea well. Gardner's translations and analysis of Zhu Xi's commentary on the _Analects_ show one of China's great thinkers in an interesting and complex act of philosophical negotiation. Through an interlinear, line-by-line "dialogue" with Confucius, Zhu effected a reconciliation of the teachings of the Master, commentary by later exegetes, and contemporary philosophical concerns of Song-dynasty scholars. By comparing Zhu's reading of the _Analects_ with the earlier standard reading by He Yan (190-249), Gardner illuminates what is dramatically new in Zhu Xi's interpretation of the _Analects._ A pioneering study of Zhu Xi's reading of the _Analects,_ this book demonstrates how commentary is both informed by a text and informs future readings, and highlights the importance of interlinear commentary as a genre in Chinese philosophy.

These commemorative papers on different aspects of Dewey's philosophy vary in quality. The essay by Paul Henle on "Dewey's Views on Truth and Verification" is excellent; and Gardner Murphy's reflections on Dewey's psychology are noteworthy. --E. S. C.

It is an irony to attack a more sceptical epistemology than one's own in the name of scepticism and defend, instead, an epistemology that is positively illogical. And yet that is what Martin Gardner has done in his “A Skeptical Look at Karl Popper.”.

Truth diagrams are introduced as a novel graphical representation for propositional logic. To demonstrate their epistemic efficacy a set of 28 concepts are proposed that any comprehensive representation for PL should encompass. TDs address all the criteria whereas seven other existing representations for PL only provide partial coverage. These existing representations are: the linear formula notation, truth tables, a PL specific interpretation of Venn Diagrams, Frege’s conceptual notation, diagrams from Wittgenstein’s Tractatus, Pierce’s alpha graphs and Gardner’s shuttle diagrams. The (...) comparison of the representations succeeds in distinguishing ideas that are fundamental to PL from features of common PL representations that are somewhat arbitrary. (shrink)

Under what circumstances if ever ought we to grant that Artificial Intelligences (AI) are persons? The question of whether AI could have the high degree of moral status that is attributed to human persons has received little attention. What little work there is employs western conceptions of personhood, while non-western approaches are neglected. In this article, I discuss African conceptions of personhood and their implications for the possibility of AI persons. I focus on an African account of personhood that is (...) prima facie inimical to the idea that AI could ever be ‘persons’ in the sense typically attributed to humans. I argue that despite its apparent anthropocentrism, this African account could admit AI as persons. (shrink)

Evidence that confirms a scientific hypothesis is said to be ‘novel’ if it is not discovered until after the hypothesis isconstructed. The philosophical issues surrounding novel confirmation have been well summarized by Campbell and Vinci [1983]. They write that philosophers of science generally agree that when observational evidence supports a theory, the confirmation is much stronger when the evidence is ‘novel’... There are, nevertheless, reasons to be skeptical of this tradition... The notion of novel confirmation is beset with a theoretical (...) puzzle about how the degree of confirmation can change without any change in the evidence, hypothesis, or auxiliary assumptions... There have not yet appeared any obviously satisfactory solutions to these problems Much of the literature on novel confirmation relies on the Bayesian analysis of conditional probabilities. Let H represent a hypothesis, E an event that confirms the hypothesis, and B some relevant background information. Denote by Pr the conditional probability of x given y. There are various plausible measures of the degree of support that E lends to H. Among these are: Degree of support = Pr Degree of support = Pr – Pr Degree of support = Pr – Pr Degree of support = Pr – Pt In the work cited, Campbell and Vinci offer a somewhat more involved Bayesian interpretation. Formula is discussed by Gardner [1981] who points out that under this formulation there can be no role for novelty. 'The function Pr contains no third slot in which to insert a temporal relation between the invention of H and the inventor's learning E. Obviously, then, this relation could not possibly affect E's support of H.' Formula, on the other hand, suggests a role for novelty. Bayes's Theorem allows us to rewrite the formula as Degree of support = Pr x [Pr – 1] We can use 1/Pr as a measure of the novelty of E. Then shows that the degree of support increases with novelty of E. In the paper already cited, Campbell and Vinci discuss shortcomings of this analysis. Formula expresses an alternative offered by Howson [1984]. In that formula, Pr represents the probability of H assuming that only B – {E} is known. This allows for the possibility of non-novel facts generating support for hypotheses. Niiniluoto [1984] argues for a variant along the lines of, in which we account for the possibility that the theorist was unaware that his hypothesis entails E. One problem in deciding among these approaches is that the choice of a definition for the degree of support appears arbitrary. What kind of argument could justify the choice of one definition over another? It is our position that there can be no basis for addressing this question in the absence of an explicit model of the process by which hypotheses are generated. Only in the presence of such a model can the various conditional probabilities be given meaningful interpretations. We provide such models in Sections 1, 2 and 4. The simple model of Section 1, incorporating strong assumptions, yields the conclusion that novelty is irrelevant. When these assumptions are relaxed in the later sections, novelty becomes relevant for a variety of reasons. It is at least potentially the case that scientists have more information about their own abilities than is publicly available, and this information might influence their decisions about whether even to attempt novel prediction. If this is so, then it should be incorporated into the model of hypothesis generation. This requires an explicit discussion of how scientists respond to incentives and how the incentives themselves evolve, which in turn takes us into the realm of economic theory. We have addressed these issues in another paper, written for an audience of economists. The results of this research are summarized in Section 3. (shrink)

This is one of the seminal articles of the pragmatist tradition where C.S. Peirce sets out his doctrine of doubt and belief --and their relationship to inquiry and clarity of our concepts. Originally published in the Popular Science Monthly; and widely available in reprints and collections of Peirce's writings.

“Probably Peirce’s best-known works are the first two articles in a series of six that originally were collectively entitled Illustrations of the Logic of Science and published in Popular Science Monthly from November 1877 through August 1878. The first is entitled ‘The Fixation of Belief’ and the second is entitled ‘How to Make Our Ideas Clear.’ In the first of these papers Peirce defended, in a manner consistent with not accepting naive realism, the superiority of the scientific method over other (...) methods of overcoming doubt and ‘fixing belief.’” — Robert Burch, “Charles Sanders Peirce,” entry in the Stanford Encyclopedia of Philosophy (2021 revision) -/- “Pragmatist epistemologies often explore how we can carry out inquiries in a self-controlled and fruitful way. (Where much analytic epistemology centres around the concept of knowledge, considered as an idealised end-point of human thought, pragmatist epistemology centres around the concept of inquiry, considered as the process of knowledge-seeking and how we can improve it.) So pragmatists often provide rich accounts of the capacities or virtues that we must possess in order to inquire well, and the rules or guiding principles that we should adopt. A canonical account is Peirce’s classic early paper ‘The Fixation of Belief‘. Here Peirce states that inquiry is a struggle to replace doubt with “settled belief“, and that the only method of inquiry that can make sense of the fact that at least some of us are disturbed by inconsistent beliefs, and will subsequently reflect upon which methods of fixing belief are correct is the Method of Science, which draws on the Pragmatic Maxim described above. This contrasts with three other methods of fixing belief: i) refusing to consider evidence contrary to one’s favored beliefs (the Method of Tenacity), ii) accepting an institution’s dictates (the Method of Authority), iii) developing the most rationally coherent or elegant-seeming belief-set (the A Priori Method).“ — Catherine Legg, “Pragmatism,” entry in the Stanford Encyclopedia of Philosophy (2021 revision).

Forty years after his death, Hans Kelsen (1881-1973) remains one of the most discussed and influential legal philosophers of our time. This collection of new essays takes Kelsen's Pure Theory of Law as a stimulus, aiming to move forward the debate on several central issues in contemporary jurisprudence. The essays in Part I address legal validity, the normativity of law, and Kelsen's famous but puzzling idea of a legal system's 'basic norm'. Part II engages with the difficult issues raised by (...) the social realities of law and the actual practices of legal officials. Part III focuses on conceptual features of legal systems and the logical structure of legal norms. All the essays were written for this volume by internationally renowned scholars from seven countries. Also included, in English translation, is an important polemical essay by Kelsen himself.

C. S. Lewis sets out to disentangle this knotty issue but wisely adds that in the end no intellectual solution can dispense with the necessity for patience and ...

A repackaged edition of the revered author's classic work that examines the four types of human love: affection, friendship, erotic love, and the love of God—part of the C. S. Lewis Signature Classics series. C.S. Lewis—the great British writer, scholar, lay theologian, broadcaster, Christian apologist, and bestselling author of Mere Christianity, The Screwtape Letters, The Great Divorce, The Chronicles of Narnia, and many other beloved classics—contemplates the essence of love and how it works in our daily lives in one of (...) his most famous works of nonfiction. Lewis examines four varieties of human love: affection, the most basic form; friendship, the rarest and perhaps most insightful; Eros, passionate love; charity, the greatest and least selfish. Throughout this compassionate and reasoned study, he encourages readers to open themselves to all forms of love—the key to understanding that brings us closer to God. (shrink)

C. S. Lewis sets out to persuade his audience of the importance and relevance of universal values such as courage and honor in contemporary society.

This article evaluates the moral status of hominins, and obligations we may have towards them. In exploring these ethical considerations, I consider one of the most recent hominin finds: the ‘graveyard’ of Homo naledi in the Dinaledi caves at the Cradle of Humankind in South Africa. I argue that findings about H. naledi establish a pro tanto duty not to excavate their remains.

C. S. Lewis takes us on a profound journey through both heaven and hell in this engaging allegorical tale. Using his extraordinary descriptive powers, Lewis introduces us to supernatural beings who will change the way we think about good and evil.
