This paper argues that Umberto Eco had a sophisticated theory of abductive reasoning and that this theory is fundamentally akin to Peirce’s both in the analysis and in the justification of this kind of reasoning. The first section expounds the essentials of Peirce’s theory of abduction, and explains how Peirce moved from seeing abduction as a kind of reasoning to seeing it as a stage of the larger process of inquiry. The second section deals with one of Eco’s paradigmatic examples (...) of abduction, i.e., William of Baskerville’s abduction concerning the horse Brunellus in the overture of The Name of the Rose, and shows that, just like in Peirce’s three-stages model of inquiry, William’s abductions are verified by means of deduction and induction. The third section examines the problem of the justification of abductive reasoning, and argues that both Peirce and Eco solved this problem through the idea that the justification of abduction is itself abductive (meta-abduction in Eco, ur-abduction in Peirce).

Abstract:"Issues of Pragmaticism" (1905) contains the only published version of Peirce's doctrine of "critical common-sensism." One of the claims of that doctrine is that common sense beliefs are invariably vague. In this paper, we seek to explain this claim. We begin by providing a philological reconstruction of the drafts of "Issues of Pragmaticism" and a comparison of Peirce's several, successive expositions of critical common-sensism across those drafts. Then we examine Peirce's theory of vagueness; we show that there is both a (...) "subjectal" and a "predicative" variety of vagueness, and that Peirce construes predicative vagueness according to three distinct models. Finally, we assess in what sense, i.e., according to which of the three models, common sense beliefs may be said to be invariably vague. (shrink)

The goal of this paper is a reassessment of Peirce’s doctrine of symbol. The paper discusses a common reading of Peirce’s doctrine, according to which all and only symbols are conventional signs. Against this reading, it is argued that neither are all Peircean symbols conventional, nor are all conventional signs Peircean symbols. Rather, a Peircean symbol is a general sign, i. e., a sign that represents a general object.

According to the received view, Charles S. Peirce's theory of diagrammatic reasoning is derived from Kant's philosophy of mathematics. For Kant, only mathematics is constructive/synthetic, logic being instead discursive/analytic, while for Peirce, the entire domain of necessary reasoning, comprising mathematics and deductive logic, is diagrammatic, i.e. constructive in the Kantian sense. This shift was stimulated, as Peirce himself acknowledged, by the doctrines contained in Friedrich Albert Lange's Logische Studien (1877). The present paper reconstructs Peirce's reading of Lange's book, and illustrates (...) what, according to Peirce, was right and what was problematic in Lange's account of reasoning. It further seeks to explain how Peirce's theory of deductive reasoning was a combination of Kant's philosophy of mathematics and Lange's philosophy of logic. (shrink)

The paper seeks to explain in what sense pragmatism was for Peirce a doctrine of logic. It is argued that pragmatism is a doctrine of logic for Peirce because its maxim, the pragmatic maxim, is a maxim of the methodeutic of abduction, i.e., concerns the method of selecting hypotheses for experimental testing. The paper also connects this idea to Peirce’s 1913 thesis according to which pragmatism contributes to the security but not to the uberty of reasoning. The connection consists in (...) that by excluding hypotheses that cannot be tested, the maxim renders the whole process of reasoning more secure, while any explanatory hypotheses is “uberous” in Peirce’s sense as any other.

In this paper, it is argued that metaphysics, conceived as an inquiry into the ultimate nature of mind-independent reality, is a rationally indispensable intellectual discipline, with the a priori science of formal ontology at its heart. It is maintained that formal ontology, properly understood, is not a mere exercise in conceptual analysis, because its primary objective is a normative one, being nothing less than the attempt to grasp adequately the essences of things, both actual and possible, with a view to (...) understanding as far as we can the fundamental structure of reality as a whole. Accordingly, it is urged, the deliverances of formal ontology have a modal and epistemic status akin to those of other a priori sciences, such as mathematics and logic, rather than constituting rivals to the claims of the empirical sciences, such as physics.

This engaging volume explores and defends the claim that misanthropy is a justified attitude towards humankind in the light of how human beings both compare with and treat animals. Reflection on differences between humans and animals helps to confirm the misanthropic verdict, while reflection on the moral and other failings manifest in our treatment of animals illuminates what is wrong with this treatment. Human failings, it is argued, are too entrenched to permit optimism about the future of animals, but ways (...) are proposed in which individual people may accommodate to the truth of misanthropy through cultivating mindful, humble and compassionate relationships to animals. Drawing on both Eastern and Western philosophical traditions David E. Cooper offers an original and challenging approach to the complex field of animal ethics. (shrink)

Philosophers constantly discuss Responsibility. Yet in every discussion of which I am aware, a rather obvious point is ignored. The obvious point is that responsibility is ascribed to collectives, as well as to individual persons. Blaming attitudes are held towards collectives as well as towards individuals. Responsibility is often ascribed to nations, towns, clubs, groups, teams, and married couples. ‘Germany was responsible for the Second World War’; ‘The club as a whole is to blame for being relegated’. Such statements are (...) not rare. (shrink)

Cet article est un nouvel examen des objections soulevées par Leibniz dans la controverse avec Clarke contre la théorie absolutiste de l'espace et du temps. Or la plupart de ces objections sont fondées sur le principe de raison suffisante; mais Leibniz utilise aussi le principe de l'identité des indiscernables, qu'il prétend déduire du principe de raison suffisante . Ce qui m'intéresse c'est que Leibniz présente parfois deux versions de la même objection: l'une reposant uniquement sur le principe de raison suffisante, (...) l'autre uniquement sur le principe de l'identité des indiscernables. Se pose alors la question suivante: Leibniz aurait-il pu soulever toutes les objections qu'il voulait contre la théorie absolutiste, en utilisant seulement le principe de l'identité des indiscernables? Il me semble qu'il aurait certainement pu le faire. Et de plus, je crois que si Leibniz avait suivi cette voie, son raisonnement contre la théorie absolutiste aurait été beaucoup plus convaincant. Ainsi donc, je me propose de mener l'attaque de Leibniz contre la théorie absolutiste, en isolant, reformulant, et exposant systématiquement sept arguments dont il se servait ou dont il aurait pu se servir, qui sont tous fondés sur le principe de l'identité des indiscernables.

The behavior of individuals currently living will generally have long-term consequences that affect the well-being of those who will come to live in the future. Intergenerational interdependencies of this nature raise difficult moral issues because only the current generation is in a position to decide on actions that will determine the nature of the world in which future generations will live. Although most are willing to attach some weight to the interests of future generations, many would argue that it is (...) not necessary to treat these interests as equivalent to those of the current generation. A common approach in this context is to use a system of discounting to evaluate future benefits and harms. This paper assesses the logic of discounting drawing on the writings of economists and philosophers. Much of the economic literature concerns the choice of an appropriate social discount rate. The social discount rate can be taken to reflect beliefs about the rights of future generations, a subject that has been extensively debated in the phioosophic literature. The writings of both economists and philosophers concerned with the weight to attach to the interests of future generations are reviewed and evaluated in this paper and the implications for environmental policy are discussed.

I argue that to be compelled to do routine work is to be gravely harmed. Indeed, that pink - collar work is a more serious harm to women than rape. My purpose is to urge politically active feminists and feminist organizations to arrange their priorities accordingly and devote most of their resources to working for the elimination of sex segregation in employment.

Both articles in the November‐December 2021 issue of the Hastings Center Report reflect bioethics’ growing interest in questions of justice, or more generally, questions of how collective interests constrain individual interests. Hugh Desmond argues that human enhancement should be reconsidered in light of developments in the field of human evolution. Contemporary understandings in this area lead, he argues, to a new way of thinking about the ethics of enhancement—an approach that replaces personal autonomy with group benefit as the primary criterion (...) for deciding what enhancements are acceptable. In the second article, Johannes Kniess considers the many attempts within bioethics to draw on John Rawls's work to discuss health care access and social determinants of health, and he comes across as moderately optimistic that Rawls's theory of justice has ongoing relevance.

Individual differences on a variety of framing and conjunction problems were examined in light of Slovic and Tversky's (1974) understanding/acceptance principle-that more reflective and skilled reasoners are more likely to affirm the axioms that define normative reasoning and to endorse the task construals of informed experts. The predictions derived from the principle were confirmed for the much discussed framing effect in the Disease Problem and for the conjunction fallacy on the Linda Problem. Subjects of higher cognitive ability were disproportionately likely (...) to avoid each fallacy. Other framing problems produced much more modest levels of empirical support. It is conjectured that the varying patterns of individual differences are best explained by two-process theories of reasoning (e.g. Evans, 1984, 1996; Sloman, 1996) conjoined with the assumption that the two processes differentially reflect interactional and analytic intelligence.

Objects which philosophers have traditionally categorized as abstract are standardly referred to by complex noun phrases of certain canonical forms, such as ‘the set of Fs’, ‘the number of Fs’, ‘the proposition that P’, and ‘the property of being F’. It is no accident that such noun phrases are well-suited to appear in ‘Fregean’ identity-criteria, or ‘abstraction’ principles, for which Frege’s criterion of identity for cardinal numbers provides the paradigm. Notoriously, such principlesare apt to create paradoxes, and the most intuitively (...) plausible ‘Fregean’ identity-criterion for properties is afflicted by this problem. In this case, it may be possible to overcome the difficulty by modifying the criterion in a way which requires an independent account of the existence-conditions of properties, but it appears that such a strategy demands acceptance of the doctrine of immanent realism—the view that a property exists only if it is exemplified by some object.

This paper locates its genesis in a small town called Vitebsk in Belorussia which experienced a flowering of creativity and artistic energy that led to significant modernist experimentation in the years 1917–1921. Marc Chagall, returning from the October Revolution took up the position of art commissioner and developed an academy of art that became the laboratory for Russian modernism. Chagall’s Academy, Bakhtin’s Circle, and Malevich’s experiments, artistic group UNOVIS—all in fierce dialogue with one another—made the town of Vitebsk into an (...) artistic crucible in the early twentieth century. We argue that this creative collective transformed creative energies of Russian drama, music, theatre, art, and philosophy in a distinctive contribution to modernism, structuralism and formalism that contributed richly to the social understanding of creativity itself that is so evident across Mikhail Bakhtin’s subsequent body of work, and elsewhere across the world. This paper argues that a consideration of such interplay has much potential for twenty-first century educational philosophy. (shrink)

I venture to call the attention of classical scholars to two legends about Roman Emperors gleaned amid the arid waste of theological nonsense which passed for literature among the Copts, in the hope that they may have better luck than I have had in tracing them to some classical source. The first is taken from MS. Par. Copte 131, fol. 40, a single leaf of what seems to be a geographical and historical encyclopaedia.1 The writer who is treating in a (...) very discursive way of Ethiopia, states that Nero or Domitian—a strange pair to run in double harness—caused an island in the Red Sea to be watered with oil. The description of that island is mixed up with a mention of the original divisions of the Indians—a term which as usual in early days embraces both Indians and Ethiopians,—and their subsequent changes; and as that too may be of interest to students of ancient geography, I will translate the passage in full.

The emergence of Latin monks, and then the spread of the monastic orders of the Catholic Church in Rus-Ukraine occurred in the conditions of political-religious transformations of the nineteenth century. Acceptance of baptism from Byzantium did not mean separation from Rome. The Eastern and Western churches were still in unity at that time. The Pope remained the formal head of all Christianity. In 988, as the Nikon Chronicle attests, the ambassadors from Rome and the relics of the saints were brought (...) to the Prince of Kiev during his march to Korsun. It was about the relics of St. Clement, the Pope, found by Cyril and Methodius in the same Korsun on his return from a missionary journey to Khazaria. Two years earlier, according to a chronicle, Vladimir had received ambassadors from Rome who had invited him to adopt Christianity in Latin. There are reports that Vladimir also sent ambassadors to Rome. (shrink)

Clinical diagnostic medicine is an experimental science based on observation, hypothesis making, and testing. It is an use dynamic process that involves observation and summary, diagnostic conjectures, testing, review, observation and summary, new or revised conjectures, i.e. it is an iterative process. It can then be said that diagnostic hypotheses are also ‘observation-laden’. My aim is to enlarge on the strategies of medical diagnosis as these are meshed in training and clinical experience—that is, to describe the patterns of reasoning used (...) by experienced clinicians under different diagnostic circumstances and how these patterns of inquiry allow further insight into the evaluation and treatment of patients. I do not aim to present a theory and illustrate it with examples; I wish rather am to let a realistic example, similar to actual clinical scenarios, direct the exposition. To this end, I introduce an account of medical diagnosis—briefly comparing and contrasting it to other accounts—in order to focus on discussing the process of diagnosis through a detailed clinical case.

Contemporary privacy theories and European discussions about data protection employ the notion of ‘personal information’ to designate their areas of concern. The notion of personal information is demarcated from non-personal information—or just information—indicating that we are dealing with a specific kind of information. However, within privacy scholarship the notion of personal information appears undertheorized, rendering the concept somewhat unclear. We argue that in an age of datafication, protection of personal information and privacy is crucial, making the understanding of what is (...) meant by ‘personal information’ more important than ever. To contribute to this aim, we analyse the conception of personal information and its nature, including the distinction between personal and non-personal information from a philosophy of language perspective. Through analyses of aboutness and relative aboutness we point to challenges related to the demarcation between personal and non-personal information, which may in practice lead to all information being personal.

E. H. Gombrich’s bestselling history of the world for young readers tells the story of mankind from the Stone Age to the atomic bomb, focusing not on small detail but on the sweep of human experience, the extent of human achievement, and the depth of its frailty. The product of a generous and humane sensibility, this timeless account makes intelligible the full span of human history. In forty concise chapters, Gombrich tells the story of man from the stone age to (...) the atomic bomb. In between emerges a colorful picture of wars and conquests, grand works of art, and the spread and limitations of science. This is a text dominated not by dates and facts, but by the sweep of mankind’s experience across the centuries, a guide to humanity’s achievements and an acute witness to its frailties. (shrink)

Context: Phenomenology and the enactive approach pose a unique challenge to dream research: during sleep one seems to be relatively disconnected from both world and body. Movement and perception, prerequisites for sensorimotor subjectivity, are restricted; the dreamer’s experience is turned inwards. In cognitive neurosciences, on the other hand, the generally accepted approach holds that dream formation is a direct result of neural activations in the absence of perception, and dreaming is often equated with “delusions.” Problem: Can enactivism and phenomenology account (...) for the variety of dream experiences? What kinds of experiential and empirical approaches are required in order to probe into dreaming subjectivity? Investigating qualities of perception, sensation, and embodiment in dreams, as well as the relationship between the dream-world and waking-world requires a step away from a delusional or altered-state framework of dream formation and a step toward an enactive integrative approach. Method: In this article, we will focus on the “depth” of dream experiences, i.e., what is possible in the dream state. Our article is divided into two parts: a theoretical framework for approaching dreaming from an enactive cognition standpoint; and discussion of the role and strategies for experimentation on dreaming. Based on phenomenology and theories of enactivism, we will argue for the primacy of subjectivity and imagination in the formation of lived experience. Results: We propose that neurophenomenology of dreaming is a nascent discipline that requires rethinking the relative role of third-, first- and second-person methodologies, and that a paradigm shift is required in order to investigate dreaming as a phenomenon on a continuum of conscious phenomena as opposed to a break from or an alteration of consciousness. Implications: Dream science, as part of the larger enterprise of consciousness and subjectivity studies, can be included in the enactive framework. This implies that dream experiences are neither passively lived nor functionally disconnected from dreamers’ world and body. We propose the basis and some concrete strategies for an empirical enactive neurophenomenology of dreaming. We conclude that investigating dream experiences can illuminate qualities of subjective perception and relation to the world, and thus challenge the traditional subject-object juxtaposition. Constructivist content: This article argues for an interdisciplinary enactive cognitive science approach to dream studies. (shrink)

This paper assesses several prominent recent attacks on the view that epistemic justification is conceptually prior to knowledge. I argue that this view—call it the Received View (RV)—emerges from these attacks unscathed. I start with Timothy Williamson’s two strongest arguments for the claim that all evidence is knowledge (E>K), which impugns RV when combined with the claim that justification depends on evidence. One of Williamson’s arguments assumes a false epistemic closure principle; the other misses some alternative (to E>K) explanations of (...) a putative fact about the evidence a particular subject has. Next, I neutralize each of Jonathan Sutton’s three recent arguments to the conclusion that any justified belief constitutes knowledge. Finally, I consider a recent analysis of justification due to Alexander Bird, according to which justified belief is possible knowledge. I argue that Bird’s analysis delivers neither a sufficient nor (more importantly) a necessary condition for justification. [Word count: 149]. (shrink)

It is a thankless task to have to reply to Professor Murray Krieger’s “Retrospective.” Qui s’excuse, s’accuse, and since I cannot ask my readers to embark on their own retrospective of my writings and test them for consistency, I have little chance of restoring my reputation in their eyes. Hence I would have been happier to leave Professor Krieger to his agonizing, if he did not present himself the “spokesman” for a significant body of theorists who appear to have acclaimed (...) my book on Art and Illusion without ever having read it. The followers of this school of criticism—of which Professor Krieger is a prominent member—had apparently convinced themselves that the book lent support to an aesthetics in which the notions of reality and of nature had no place. They thought that I had subverted the old idea of mimesis and that all that remained were different systems of conventional signs which were made to stand for an unknowable reality. True, professor Krieger admits that I never endorsed such an interpretation of my views, and he even concedes that there are passages in Art and Illusion which contradict such an out-and-out relativism, but he wants to convince his readers that these contradictions lead precisely to the ambiguities he now proposes to analyse.If he were right that the book encourages such a misreading, all I could do would be to express my regrets for having failed to make myself sufficiently clear. Luckily I can draw comfort from the fact that unlike these literary critics, the leading archaeologist of this country, Professor Stuart Piggott, had no difficulty at all in discerning my meaning and profiting from my arguments. In his Walter Neurath Memorial Lecture of 1978, entitled Antiquity Depicted: Aspects of Archaeological Illustration, the author did me the honour of taking a statement from my book as his starting point. It is the passage at the end of part I in which I recapitulate the content of the first two chapters:What matters to us is that the correct portrait, like the useful map, is an end product on a long road through schema and correction. It is not a faithful record of a visual experience but the faithful construction of a relational mode.Neither the subjectivity of vision nor the sway of conventions need lead us to deny that such a model can be constructed to any required degree of accuracy. What is decisive here is clearly the word “required.” The form of a representation cannot be divorced from its purpose and the requirements of the society in which the given visual language gains currency.1 1.

The contention that abortion harms women constitutes a new strategy employed by the pro-life movement to supplement arguments about fetal rights. David C. Reardon is a prominent promoter of this strategy. Post-abortion syndrome purports to establish that abortion psychologically harms women and, indeed, can harm persons associated with women who have abortions. Thus, harms that abortion is alleged to produce are multiplied. Claims of repression are employed to complicate efforts to disprove the existence of psychological harm and causal antecedents of (...) trauma are only selectively investigated. We argue that there is no such thing as post-abortion syndrome and that the psychological harms Reardon and others claim abortion inflicts on women can usually be ascribed to different causes. We question the evidence accumulated by Reardon and his analysis of data accumulated by others. Most importantly, we question whether the conclusions Reardon has drawn follow from the evidence he cites. (shrink)

Oncogenic hyperplasia is the first and inevitable stage of formation of a (solid) tumor. This stage is also the core of many other proliferative diseases. The present work proposes the first minimal model that combines homeorhesis with oncogenic hyperplasia where the latter is regarded as a genotoxically activated homeorhetic dysfunction. This dysfunction is specified as the transitions of the fluid of cells from a fluid, homeorhetic state to a solid, hyperplastic-tumor state, and back. The key part of the model is (...) a nonlinear reaction-diffusion equation (RDE) where the biochemical-reaction rate is generalized to the one in the well-known Schlögl physical theory of the non-equilibrium phase transitions. A rigorous analysis of the stability and qualitative aspects of the model, where possible, are presented in detail. This is related to the spatially homogeneous case, i.e. when the above RDE is reduced to a nonlinear ordinary differential equation. The mentioned genotoxic activation is treated as a prevention of the quiescent G0-stage of the cell cycle implemented with the threshold mechanism that employs the critical concentration of the cellular fluid and the nonquiescent-cell-duplication time. The continuous tumor morphogeny is described by a time-space-dependent cellular-fluid concentration. There are no sharp boundaries (i.e. no concentration jumps exist) between the domains of the homeorhesis- and tumor-cell populations. No presumption on the shape of a tumor is used. To estimate a tumor in specific quantities, the model provides the time-dependent tumor locus, volume, and boundary that also points out the tumor shape and size. The above features are indispensable in the quantitative development of antiproliferative drugs or therapies and strategies to prevent oncogenic hyperplasia in cancer and other proliferative diseases. The work proposes an analytical-numerical method for solving the aforementioned RDE. A few topics for future research are suggested. (shrink)
