I argue against the tendency in the philosophy of science literature to link abduction to the inference to the best explanation (IBE), and in particular, to claim that Peireean abduction is a conceptual predecessor to IBE. This is not to discount either abduction or IBE. Rather the purpose of this paper is to clarify the relation between Peireean abduction and IBE in accounting for ampliative inference in science. This paper aims at a proper classification—not justification—of types of scientific reasoning. In (...) particular, I claim that Peireean abduction is an in-depth account of the process of generating explanatory hypotheses, while IBE, at least in Peter Lipton's thorough treatment, is a more encompassing account of the processes both of generating and of evaluating scientific hypotheses. There is then a two-fold problem with the claim that abduction is IBE. On the one hand, it conflates abduction and induction, which are two distinct forms of logical inference, with two distinct aims, as shown by Charles S. Peirce; on the other hand it lacks a clear sense of the full scope of IBE as an account of scientific inference. (shrink)

I address the philosophical debate over whether the mathematical theory of probability arose on the basis of empirical observations or of purely theoretical speculations. The debate tends to pose a strict dichotomy between empirical problem-solving and pure theorizing. I alternatively suggest that, in the case of mathematical probability, an empirical problem-context acted as an enabling condition for the possibility of mathematical innovation, but that the activity of the early mathematical probabilists gradually became the study of a theoretical system of ideas. (...) This case has some implications for a more general philosophical view on the context of mathematical discovery. ---------------------------------------------------------------------------------------------------- ---------------------------------------------------------------------------------------------------- ---------------------------------------------------------------------------------------------------- ---------------------------------------------------------------------------------------------------- ---------------------------------------------------------------------------------------------------- ---------------------------------------------------------------------------------------------------- ----------------------------------------.

: C.S. Peirce defines mathematics in two ways: first as "the science which draws necessary conclusions," and second as "the study of what is true of hypothetical states of things" (CP 4.227–244). Given the dual definition, Peirce notes, a question arises: Should we exclude the work of poietic hypothesis-making from the domain of pure mathematical reasoning? (CP 4.238). This paper examines Peirce's answer to the question. Some commentators hold that for Peirce the framing of mathematical hypotheses requires poietic genius but (...) is not scientific work. I propose, to the contrary, that although Peirce occasionally seems to exclude the poietic creation of hypotheses altogether from pure mathematical reasoning, Peirce's position is rather that the creation of mathematical hypotheses is poietic, but it is not merely poietic, and accordingly, that hypothesis-framing is part of mathematical reasoning that involves an element of poiesis but is not merely poietic either. Scientific considerations also inhere in the process of hypothesis-making, without excluding the poietic element. In the end, I propose that hypothesis-making in mathematics stands between artistic and scientific poietic creativity with respect to imaginative freedom from logical and actual constraints upon reasoning.

Henry David Thoreau’s discussion of the highest value of wild apples and my own reflection upon my experience, interacting with the sea and enjoying its products during my Central American upbringing, motivate this discussion of how human beings may apprehend nature’s highest worth. I propose that in order to apprehend nature’s highest value it is necessary to understand the complete transaction between human beings and nature—an active transaction that requires from the human being a continuous movement along experience, reflection, and (...) responsible action. I argue that the economic valuation of natural products—via the contemporary economic concepts of utility, use-value, existence-value, and willingness-to-pay—is insufficient to comprehend the full worth of nature because it reduces the human being-nature transaction to mere economic terms. Hence, a reading of Ralph Waldo Emerson’s Nature provides insight into the services—commodity, beauty, language, and discipline—that the human being receives, as part of the transaction, from nature. In turn, a reading of Aldo Leopold’s A Sand County Almanac complements the Emersonian position by considering the human being’s position as a member of a natural community. Finally, I propose that in order to apprehend the worth of nature, it is further necessary to move from the reflective understanding of the human being-nature transaction into necessary action, that is, into the assumption of responsibility towards nature.

in two letters concerning the Spanish-American War of 1898, Charles Sanders Peirce openly expresses some egregious prejudices against several groups of people, including Hispanics—people of at least partly Spanish origin in the Iberian Peninsula or the Americas (L 254 and L 339; reprint, translation to Spanish, and commentary in Nubiola and Zalamea 76–811). In an undated letter to his cousin Henry Cabot Lodge, a Massachusetts politician, Peirce writes regarding the war: “I don’t believe the Spaniards will make a good fight; (...) for as I have studied them in Spain, the whole people has been corrupted with the centuries of cruelty, injustice and rapine they have indulged in, and have little real manhood left” (L 254; ..

in their book American Philosophy: From Wounded Knee to the Present, contemporary philosophers Erin McKenna and Scott Pratt identify "living in a context of difference" as the central philosophical issue in the history of the United States. They credit W. E. B. Du Bois with having identified racial difference as one particular version of this general issue: "Du Bois once declared that the problem of the twentieth century is the problem of the color line—the problem of the coexistence of differences (...) that figure in our existence as members of communities". For McKenna and Pratt, this continues to be the central philosophical problem in the United States, and perhaps globally, today: "From the... (shrink)

I articulate Charles S. Peirce’s philosophy of mathematical education as related to his conception of mathematics, the nature of its method of inquiry, and especially, the reasoning abilities required for mathematical inquiry. The main thesis is that Peirce’s philosophy of mathematical education primarily aims at fostering the development of the students’ semeiotic abilities of imagination, concentration, and generalization required for conducting mathematical inquiry by way of experimentation upon diagrams. This involves an emphasis on the relation between theory and practice and (...) between mathematics and other fields including the arts and sciences. For achieving its goals, the article is divided in three sections. First, I expound Peirce’s philosophical account of mathematical reasoning. Second, I illustrate this account by way of a geometrical example, placing special emphasis on its relation to mathematical education. Finally, I put forth some Peircean philosophical principles for mathematical education. (shrink)

This book is a Spanish translation of two of Charles S. Peirce's late texts on pragmatism, namely, "What Pragmatism Is" (originally published in The Monist, 1905) and "Pragmatism" (MS 318, 1907).1 The essays are introduced by translator Sara Barrena, who based her edition on the texts published in The Essential Peirce.2 The introduction consists of brief sections that present a biographical sketch of Peirce; an account of his original formulation of pragmatism; a summary of its evolution into his later pragmaticism, (...) including a synthesis of his arguments in the two translated texts; and Barrena's own conclusions about the import of Peirce's pragmaticism in the context of his philosophical system.

The purpose of this paper is to explore the evolution of the philosophical analysis of sport in Latin America from the nineteenth century to the present. To do so, this paper identifies the main themes and the leading works that emerged throughout this period as well as their relation to regional philosophical traditions. Likewise, to situate the philosophical analysis of sport in Latin America in a broader perspective, this paper makes reference to its relation to the philosophy of sport in (...) parts of the English-speaking world and the Iberian Peninsula . This paper also includes an account of the character and extent of philosophical thinking in relation to sport in contemporary Latin America and speculations about the future of the discipline in the region.

For the epic journey of autumn migration, long-distance migratory birds use innate and learned information and follow strict schedules imposed by genetic and epigenetic mechanisms, the details of which remain largely unknown. In addition, bird migration requires integrated action of different multisensory systems for learning and memory, and the hippocampus appears to be the integration center for this task. In previous studies we found that contrasting long-distance migratory flights differentially affected the morphological complexity of two types of hippocampus astrocytes. Recently, (...) a significant association was found between the latitude of the reproductive site and the size of the ADCYAP1 allele in long distance migratory birds. We tested for correlations between astrocyte morphological complexity, migratory distances, and size of the ADCYAP1 allele in three long-distance migrant species of shorebird and one non-migrant. Significant differences among species were found in the number and morphological complexity of the astrocytes, as well as in the size of the microsatellites of the ADCYAP1 gene. We found significant associations between the size of the ADCYAP1 microsatellites, the migratory distances, and the degree of morphological complexity of the astrocytes. We suggest that associations between astrocyte number and morphological complexity, ADCYAP1 microsatellite size, and migratory behavior may be part of the adaptive response to the migratory process of shorebirds.

This paper describes KRL, a Knowledge Representation Language designed for use in understander systems. It outlines both the general concepts which underlie our research and the details of KRL‐0, an experimental implementation of some of these concepts. KRL is an attempt to integrate procedural knowledge with a broad base of declarative forms. These forms provide a variety of ways to express the logical structure of the knowledge, in order to give flexibility in associating procedures (for memory and reasoning) with specific (...) pieces of knowledge, and to control the relative accessibility of different facts and descriptions. The formalism for declarative knowledge is based on structured conceptual objects with associated descriptions. These objects form a network of memory units with several different sorts of linkages, each having well‐specified implications for the retrieval process. Procedures can be associated directly with the internal structure of a conceptual object. This procedurul attachment allows the steps for a particular operation to be determined by characteristics of the specific entities involved.The control structure of KRL is based on the belief that the next generation of intelligent programs will integrate data‐directed and goal‐directed processing by using multiprocessing. It provides for a priority‐ordered multiprocess agenda with explicit (user‐provided) strategies for scheduling and resource allocation. It provides procedure directories which operate along with process frameworks to allow procedural parameterization of the fundamental system processes for building, comparing, and retrieving memory structures. Future development of KRL will include integrating procedure definition with the descriptive formalism. (shrink)

The Giving Voice to Values pedagogy and curriculum is described as an example of a powerful leverage point in the integration of business ethics and values-driven leadership across the business curriculum. GVV is post-decision-making in that it identifies an ethical course of action and asks practitioners to identify who are the parties involved and what’s at stake for them; what are the main arguments to be countered; and what levers that can be used to influence those who are in disagreement. (...) The internalization of GVV’s constructs allows faculty to comfortably raise and endorse ethics as part of the natural order of business decision-making because the stakes of doing so have been normalized. Methods for introducing and using GVV in undergraduate through MBA courses are given. An illustration is given for economics courses. (shrink)

This study examines the deliberations of professional MBA students when presented with a dilemma that weighs the difference between commitments to profit-maximization against concerns for fired workers who would need to seek a new job during a recession. Using content analysis, accounting, economic, and ethically based rationales that differ from the profit-maximizing recommendation are categorized. Results also show that those who make non-profit-maximizing recommendations consider, but ultimately reject the profit-maximizing approach to layoffs.

The 1980s witnessed a dramatic increase in hostile takeovers in the United States. Proponents argue that well- planned mergers enhance the value of the firm and the value of the firm to society. Critics typically argue that undesired takeovers ultimately harm society due to external costs not borne by the acquiring firm. To be socially responsible, the manager must consider the effects of the merger/acquisition on all stakeholders. Different traditional ethical frameworks for decision making are proposed and reviewed. A model (...) is proposed. (shrink)

This paper gives prescriptions for introducing ethical concerns into the economic theory of the firm. Topics include social responsibility, corporate governance, profit maximization, competition barriers, collusion, the market system, and welfare economics. The need for such prescriptions is based on a content analysis of 21 managerial economics texts for their coverage of ethics. My analysis finds that substantive discussions of ethics are conspicuous by their absence. As ethical breaches can involve significant monetary damages to a firm - particularly through adverse (...) market reactions - moral-reasoning abilities can complement analytical skills. Consequently, my analysis demonstrates how ethics figure into the opportunity costs of managerial decision making, which is central to the economic definition of profit. (shrink)

[Correction Notice: An erratum for this article was reported in Vol 109 of Psychological Review. Due to circumstances that were beyond the control of the authors, the studies reported in "Models of Ecological Rationality: The Recognition Heuristic," by Daniel G. Goldstein and Gerd Gigerenzer overlap with studies reported in "The Recognition Heuristic: How Ignorance Makes Us Smart," by the same authors and with studies reported in "Inference From Ignorance: The Recognition Heuristic". In addition, Figure 3 in the Psychological Review (...) article was originally published in the book chapter and should have carried a note saying that it was used by permission of Oxford University Press.] One view of heuristics is that they are imperfect versions of optimal statistical procedures considered too complicated for ordinary minds to carry out. In contrast, the authors consider heuristics to be adaptive strategies that evolved in tandem with fundamental psychological mechanisms. The recognition heuristic, arguably the most frugal of all heuristics, makes inferences from patterns of missing knowledge. This heuristic exploits a fundamental adaptation of many organisms: the vast, sensitive, and reliable capacity for recognition. The authors specify the conditions under which the recognition heuristic is successful and when it leads to the counter-intuitive less-is-more effect in which less knowledge is better than more for making accurate inferences.

Two institutions that are often implicit or overlooked in noncooperative games are the assumption of Nash behavior to solve a game, and the ability to correlate strategies. We consider two behavioral paradoxes; one in which maximin behavior rules out all Nash equilibria (‘Chicken’), and another in which minimax supergame behavior leads to an ‘inefficient’ outcome in comparison to the unique stage game equilibrium (asymmetric ‘Deadlock’). Nash outcomes are achieved in both paradoxes by allowing for correlated strategies, even when individual behavior (...) remains minimax or maximin. However, the interpretation of correlation as a public institution differs for each case. (shrink)

We experimentally assess the ethics of the U.S. government’s indirect bailout of the bank counterparties of American International Group during the 2008 financial crisis. When the indirect bailout is jointly compared with a counterfactual where the government directly bails out the banks, subjects judge the indirect bailout to be far more unethical. On the other hand, when the two scenarios are judged separately, subjects consider a direct bailout of banks to be more unethical. This suggests that ethical judgments of indirect (...) versus direct action exhibit a type of preference reversal that is dependent upon whether the evaluation mode is joint or separate. The pedagogical and policy implications of this preference reversal are discussed. (shrink)

With increasing complexity in the evolving structure of work in organizations, employees’ preferences for working from home (WFH) relative to working on-site can lead to systematic differences in perceived career implications. An emerging tension associated with WFH versus work-at-work is whether this locational divide is associated with concerns over career progression, especially among racial minorities. Here, we seek to determine whether Black employees, relative to their White counterparts, have more concerns over career progression relating to WFH compared with their on-site (...) colleagues. From a sample of employees in the May 2021 cross-section of the Survey of Working Arrangements and Attitudes (SWAA), we find that relative to higher (lower) income White employees, higher (lower) income Black WFH employees have significantly higher (lower) concerns over career progression than their on-site counterparts. These findings speak both to the nontrivial choices employees may be forced to make as the structure of work continues to evolve and consequences for racial inequality. (shrink)

We have synthesized a 582,970-base pair Mycoplasma genitalium genome. This synthetic genome, named M. genitalium JCVI-1.0, contains all the genes of wild-type M. genitalium G37 except MG408, which was disrupted by an antibiotic marker to block pathogenicity and to allow for selection. To identify the genome as synthetic, we inserted "watermarks" at intergenic sites known to tolerate transposon insertions. Overlapping "cassettes" of 5 to 7 kilobases (kb), assembled from chemically synthesized oligonucleotides, were joined by in vitro recombination to produce intermediate (...) assemblies of approximately 24 kb, 72 kb ("1/8 genome"), and 144 kb ("1/4 genome"), which were all cloned as bacterial artificial chromosomes in Escherichia coli. Most of these intermediate clones were sequenced, and clones of all four 1/4 genomes with the correct sequence were identified. The complete synthetic genome was assembled by transformation-associated recombination cloning in the yeast Saccharomyces cerevisiae, then isolated and sequenced. A clone with the correct sequence was identified. The methods described here will be generally useful for constructing large DNA molecules from chemically synthesized pieces and also from combinations of natural and synthetic DNA segments. 10.1126/science.1151721.

This paper aims to position the birth of the Medical Humanities movement in a greater historical context of twentieth century American medical education and to paint a picture of the current landscape of the Medical Humanities in medical training. It first sheds light on the model of medical education put forth by Abraham Flexner through the publishing of the 1910 Flexner Report, which set the stage for defining physicians as experimentalists and rooting the profession in research institutions. While this paved (...) the way for medical advancements, it came at the cost of producing a patriarchal approach to medical practice. By the late 1960s, the public persona of the profession was thus devoid of humanism. This catalyzed the birth of the Medical Humanities movement that helped lay the framework for what has perpetuated as the ongoing incorporation of humanistic subjects into medical training. As we enter a time in medicine in which rates of burnout are ever-increasing and there are growing concerns about a concomitant reduction in empathy among trainees, the need for instilling humanism remains important. We must consequently continue to consider how to ensure the place of the Medical Humanities in medical education moving forward. (shrink)
