The canonical gospels are attempts to compose an inclusive and balanced presentation of the presence of God in Jesus and of the discipleship that presence evokes.

According to Luke, the resurrection takes place according to divine plan and functions variously: to signal God's reversal of Jesus' rejection; to attest to Jesus' victory over death; to confirm Jesus as the mediator of salvation; to establish the Eucharist as the extension of table fellowship with Jesus; and to make mission possible.

The approach to the Gospel of Luke which seemed certain to prevail twenty years ago has been challenged in all its significant features. The crucial questions concerning the critical interpretation of the Third Gospel are waiting new answers.

This book proposes a new paradigm for the interpretation of Plato's early and middle dialogues. Rejecting the usual assumption of a distinct 'Socratic' period in the development of Plato's thought, this view regards the earlier works as deliberate preparation for the exposition of Plato's mature philosophy. Differences between the dialogues do not represent different stages in Plato's own thinking but rather different aspects and moments in the presentation of a new and unfamiliar view of reality. Once the fictional character of (...) the Socratic genre is recognised, there is no reason to regard Plato's early dialogues as representing the philosophy of the historical Socrates. The result is a unified interpretation of all of the dialogues down to the Republic and the Phaedrus. (shrink)

Recent arguments concerning the nature of causation in evolutionary theory, now often known as the debate between the 'causalist' and 'statisticalist' positions, have involved answers to a variety of independent questions – definitions of key evolutionary concepts like natural selection, fitness, and genetic drift; causation in multi-level systems; or the nature of evolutionary explanations, among others. This Element offers a way to disentangle one set of these questions surrounding the causal structure of natural selection. Doing so allows us to clearly (...) reconstruct the approach that some of these major competing interpretations of evolutionary theory have to this causal structure, highlighting particular features of philosophical interest within each. Further, those features concern problems not exclusive to the philosophy of biology. Connections between them and, in two case studies, contemporary metaphysics and philosophy of physics demonstrate the potential value of broader collaboration in the understanding of evolution.

Philosophy of science is expanding via the introduction of new digital data and tools for their analysis. The data comprise digitized published books and journal articles, as well as heretofore unpublished material such as images, archival text, notebooks, meeting notes, and programs. The growth in available data is matched by the extensive development of automated analysis tools. The variety of data sources and tools can be overwhelming. In this article, we survey the state of digital work in the philosophy of (...) science, showing what kinds of questions can be answered and how one can go about answering them. (shrink)

The Rise of Chance in Evolutionary Theory: A Pompous Parade of Arithmetic explores a pivotal conceptual moment in the history of evolutionary theory: the development of its extensive reliance on a wide array of concepts of chance. It tells the history of a methodological and conceptual development that reshaped our approach to natural selection over a century, ranging from Darwin’s earliest notebooks in the 1830s to the early years of the Modern Synthesis in the 1930s. Far from being a “pompous (...) parade of arithmetic,” as one early critic argued, evolution transformed during this period to make these conceptual and technical tools indispensable. This book charts the role of chance in evolutionary theory from its beginnings to the earliest days of modern evolutionary theory, making it an ideal resource for evolutionary biologists, historians, philosophers, and researchers in science studies or biological statistics.

Plato's late dialogues have often been neglected because they lack the literary charm of his earlier masterpieces. Charles Kahn proposes a unified view of these diverse and difficult works, from the Parmenides and Theaetetus to the Sophist and Timaeus, showing how they gradually develop the framework for Plato's late metaphysics and cosmology. The Parmenides, with its attack on the theory of Forms and its baffling series of antinomies, has generally been treated apart from the rest of Plato's late work. (...) Kahn shows that this perplexing dialogue is the curtain-raiser on Plato's last metaphysical enterprise: the step-by-step construction of a wider theory of Being that provides the background for the creation story of the Timaeus. This rich study, the natural successor to Kahn's earlier Plato and the Socratic Dialogue, will interest a wide range of readers in ancient philosophy and science. (shrink)

A fascinating portrait of the Pythagorean tradition, including a substantial account of the Neo-Pythagorean revival, and ending with Johannes Kepler on the threshold of modernism.

The propensity interpretation of fitness (PIF) is commonly taken to be subject to a set of simple counterexamples. We argue that three of the most important of these are not counterexamples to the PIF itself, but only to the traditional mathematical model of this propensity: fitness as expected number of offspring. They fail to demonstrate that a new mathematical model of the PIF could not succeed where this older model fails. We then propose a new formalization of the PIF that (...) avoids these (and other) counterexamples. By producing a counterexample-free model of the PIF, we call into question one of the primary motivations for adopting the statisticalist interpretation of fitness. In addition, this new model has the benefit of being more closely allied with contemporary mathematical biology than the traditional model of the PIF. (shrink)

My aim here is to make sense of Plato's account of desire in the middle dialogues. To do that I need to unify or reconcile what are at first sight two quite different accounts: the doctrine of eros in the Symposium and the tripartite theory of motivation in the Republic. It may be that the two theories are after all irreconcilable, that Plato simply changed his mind on the nature of human desire after writing the Symposium and before composing the (...) Republic. But that conclusion can be justified only if attempts to reconcile the two theories end in failure. The attempt must be made first. (shrink)

It has long been recognized that cancer onset and progression represent a type of reversion to an ancestral quasi‐unicellular phenotype. This general concept has been refined into the atavistic model of cancer that attempts to provide a quantitative analysis and testable predictions based on genomic data. Over the past decade, support for the multicellular‐to‐unicellular reversion predicted by the atavism model has come from phylostratigraphy. Here, we propose that cancer onset and progression involve more than a one‐off multicellular‐to‐unicellular reversion, and are (...) better described as a series of reversionary transitions. We make new predictions based on the chronology of the unicellular‐eukaryote‐to‐multicellular‐eukaryote transition. We also make new predictions based on three other evolutionary transitions that occurred in our lineage: eukaryogenesis, oxidative phosphorylation and the transition to adaptive immunity. We propose several modifications to current phylostratigraphy to improve age resolution to test these predictions. Also see the video abstract here: https://youtu.be/3unEu5JYJrQ. (shrink)

There is a widespread assumption that the universe in general, and life in particular, is 'getting more complex with time'. This book brings together a wide range of experts in science, philosophy and theology and unveils their joint effort in exploring this idea. They confront essential problems behind the theory of complexity and the role of life within it: what is complexity? When does it increase, and why? Is the universe evolving towards states of ever greater complexity and diversity? If (...) so, what is the source of this universal enrichment? This book addresses those difficult questions, and offers a unique cross-disciplinary perspective on some of the most profound issues at the heart of science and philosophy. Readers will gain insights in complexity that reach deep into key areas of physics, biology, complexity science, philosophy and religion. (shrink)

Behind the superficial obscurity of what fragments we have of Heraclitus' thought, Professor Kahn claims that it is possible to detect a systematic view of human existence, a theory of language which sees ambiguity as a device for the expression of multiple meaning, and a vision of human life and death within the larger order of nature. The fragments are presented here in a readable order; translation and commentary aim to make accessible the power and originality of a systematic thinker (...) and the first great master of artistic prose. The commentary locates Heraclitus within the tradition of early Greek thought, but stresses the importance of his ideas for contemporary theories of language, literature and philosophy. (shrink)

The poem of Parmenides is the earliest philosophic text which is preserved with sufficient completeness and continuity to permit us to follow a sustained line of argument. It is surely one of the most interesting arguments in the history of philosophy, and we are lucky to have this early text, perhaps a whole century older than the first dialogues of Plato. But the price we must pay for our good fortune is to face up to a vipers' nest of problems, (...) concerning details of the text and the archaic language but also concerning major questions of philosophic interpretation. These problems are so fundamental that, unless we solve them correctly, we cannot even be clear as to what Parmenides is arguing for, or why. And they are so knotted that we can scarcely unravel a single problem without finding the whole nest on our hands. (shrink)

Through criticism and analysis of ancient traditions, Kahn reconstructs the pattern of Anaximander’s thought using historical methods akin to the reconstructive techniques of comparative linguists.

There are two motivations commonly ascribed to historical actors for taking up statistics: to reduce complicated data to a mean value (e.g., Quetelet), and to take account of diversity (e.g., Galton). Different motivations will, it is assumed, lead to different methodological decisions in the practice of the statistical sciences. Karl Pearson and W. F. R. Weldon are generally seen as following directly in Galton’s footsteps. I argue for two related theses in light of this standard interpretation, based on a reading (...) of several sources in which Weldon, independently of Pearson, reflects on his own motivations. First, while Pearson does approach statistics from this "Galtonian" perspective, he is, consistent with his positivist philosophy of science, utilizing statistics to simplify the highly variable data of biology. Weldon, on the other hand, is brought to statistics by a rich empiricism and a desire to preserve the diversity of biological data. Secondly, we have here a counterexample to the claim that divergence in motivation will lead to a corresponding separation in methodology. Pearson and Weldon, despite embracing biometry for different reasons, settled on precisely the same set of statistical tools for the investigation of evolution. (shrink)

Fitness is a central theoretical concept in evolutionary theory. Despite its importance, much debate has occurred over how to conceptualize and formalize fitness. One point of debate concerns the roles of organismic and trait fitness. In a recent addition to this debate, Elliott Sober argues that trait fitness is the central fitness concept, and that organismic fitness is of little value. In this paper, by contrast, we argue that it is organismic fitness that lies at the bases of both the (...) conceptual role of fitness, as well as its role as a measure of evolutionary dynamics.

One potentially extremely fruitful use of the tools of corpus analysis in the philosophy of science is to help us understand disputed terrains within the sciences that we study. For philosophers of biology, for instance, few controversies are as heated as those over the concepts we use in taxonomy to classify the living world, with the definition of ‘species’ perhaps most fundamental among them. As many understandings of biodiversity, in turn, involve counting the number of species present in a given (...) area, these taxonomic concepts thus become crucially implicated in our efforts in conservation biology and our response to climate change. In this chapter, we present a corpus of taxonomic journal papers, and illustrate how it might be used to make progress in the history and philosophy of taxonomy. What parts of the biological world do taxonomists most often study? Are these areas of focus related to other methodological commitments, or perhaps to their underlying conceptual disagreement? Are species that are more important to conservation, or economic concerns, or more important to local cultures, more or less likely to be the target of biological study? Corpus-based methods, we argue, are uniquely powerful for approaching questions such as these, and we hope that the case we present can serve as a fruitful example for others considering their implementation.

The idea of ‘reversion’ or ‘atavism’ has a peculiar history. For many authors in the latenineteenth and early-twentieth centuries – including Darwin, Galton, Pearson, Weismann, and Spencer, among others – reversion was one of the central phenomena which a theory of heredity ought to explain. By only a few decades later, however, Fisher and others could look back upon reversion as a historical curiosity, a non-problem, or even an impediment to clear theorizing. I explore various reasons that reversion might have (...) appeared to be a central problem for this first group of figures, focusing on their commitment to a variety of conceptual features of evolutionary theory; discuss why reversion might have then ceased to be an interesting phenomenon; and, finally, close with some more general thoughts about the death of scientific problems.

This research seeks to better understand how an organization-related employee perception and job attitude may influence organizational members to ethically create customer value. Specifically, it is proposed that high person–organization fit perception, more precisely ethical values person–organization fit perception, can influence business-to-business salesperson commitment to providing superior customer value both directly and indirectly through trust in sales manager, while encouraging ethical salesforce behavior, an important aspect of communicating and delivering customer value. Results from a study of 408 business-to-business salespeople find (...) that ethical values person–organization fit positively influences salesperson commitment to providing superior customer value, as well as trust in manager. Trust in manager directly affects commitment to customer value and mediates the relationship between ethical values person–organization fit and unethical intent. Theoretical and managerial implications are provided, as well as directions for future research. (shrink)

Little is known about how ethical organizational contexts influence employees’ perceived stress levels and well-being. This study used two theoretical lenses, ethical impact theory (Promislo et al. in Handbook of Unethical Work Behavior, M.E. Sharpe, Armonk, 2013) and ethical decision-making theory (Schwartz in J Bus Ethics 139(4): 755–776, 2016), to investigate the relationships among perceived organizational ethics (comprised of ethical climate, leader/manager ethics, and corporate social responsibility), work-related stress, and employee well-being (comprised of vitality, life satisfaction, personal growth initiative, flourishing, (...) positive mental health, and self-actualization). Findings across two studies indicated that organizational ethics was negatively related to work-related stress, and that work-related stress was negatively related to employee well-being. Perceived organizational ethics is positively related to employee well-being, with post hoc mediation tests indicating that work-related stress partially mediates this relationship. Our findings suggest that organizations should be proactive in improving their ethical climate, such as choosing ethical leaders, developing a robust and well-communicated code of ethics, and actively practicing CSR. These measures should reduce excessive work-related stress and improve employee well-being. (shrink)

There are a bewildering variety of claims connecting Darwin to nineteenth-century philosophy of science—including to Herschel, Whewell, Lyell, German Romanticism, Comte, and others. I argue here that Herschel’s influence on Darwin is undeniable. The form of this influence, however, is often misunderstood. Darwin was not merely taking the concept of “analogy” from Herschel, nor was he combining such an analogy with a consilience as argued for by Whewell. On the contrary, Darwin’s Origin is written in precisely the manner that one (...) would expect were Darwin attempting to model his work on the precepts found in Herschel’s Preliminary Discourse on Natural Science. While Hodge has worked out a careful interpretation of both Darwin and Herschel, drawing similar conclusions, his interpretation misreads Herschel’s use of the vera causa principle and the verification of hypotheses. The new reading that I present here resolves this trouble, combining Hodge’s careful treatment of the structure of the Origin with a more cautious understanding of Herschel’s philosophy of science. This interpretation lets us understand why Darwin laid out the Origin in the way that he did and also why Herschel so strongly disagreed, including in Herschel’s heretofore unanalyzed marginalia in his copy of Darwin’s book.
