One hotly debated philosophical question in the analysis of evolutionary theory concerns whether or not evolution and the various factors which constitute it may profitably be considered as analogous to “forces” in the traditional, Newtonian sense. Several compelling arguments assert that the force picture is incoherent, due to the peculiar nature of genetic drift. I consider two of those arguments here – that drift lacks a predictable direction, and that drift is constitutive of evolutionary systems – and show that they (...) both fail to demonstrate that a view of genetic drift as a force is untenable. I go on to diagnose the reasons for the stubborn persistence of this problem, considering two open philosophical issues and offering some preliminary arguments in support of the force metaphor.

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)

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.

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)

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)

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.

In his sociological works Pareto developed a theory of cyclical social change within the general equilibrium framework. Building on an earlier propositional formalization, we translate Pareto's theory into a series of simultaneous equations and simulate the equation system. The dynamic behavior of the simulation is consistent with Pareto's predictions and demonstrates the internal logic of the theory.

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)

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)

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.

A transnational enterprise is an information and decision system that directs the common strategy of business establishments operating under several jurisdictions; its objective is precise and concrete: it is to realize a profit by producing and selling goods or services, computers perhaps or hamburgers, or leisure, under such names as I.B.M. or VW, McDonald or Club Mediterranée.

With the advent of iron-built ships in the early nineteenth century the problem of managing a magnetic compass on board presented considerable difficulty. Prominent among the early scientists who tackled the problem were George Biddell Airy and William Scoresby. Airy had provided a mechanical system, employing correctors in the form of steel magnets and wrought iron masses, by which the ship's magnetic field at the compass position is neutralized. He based his system on the concept that the magnetism acquired by (...) an iron ship during her construction remained with the ship throughout her life. Scoresby, on the other hand, thought differently. After having conducted a thorough and systematic series of experiments on iron plates and bars, he concluded that the magnetic character of an iron ship is liable to sudden and unexpected change. Scoresby argued, therefore, that Airy's system was defective and, indeed, dangerous. The aim of this paper is to discuss the two views which brought Airy and Scoresby into a conflict which is documented in a series of letters to the editor of The Athenaeum. (shrink)

For many years, researchers and practitioners have sought out meaningful indicators of sales performance. Yet, as the concept of performance has broadened, the understanding of what makes up a successful seller, has become far more complicated. The complexity of buyer–seller relationships has changed therefore as the definition of sales performance has expanded, cultivating a growing interest in ethical/unethical actions since they could potentially have impacts on sales performance. Given this environment, the purpose of this study is to explore the impact (...) of moral judgment on sales performance and sellers engaging in a customer-oriented selling approach. Specifically, by utilizing a sample of 345 business-to-business salespeople, this study examines the relationships between moral judgment, customer-oriented selling, and outcome and behavior based performance. Results, managerial implications, and opportunities for future research are provided. (shrink)

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.

Este artigo analisa o conceito de bem na filosofia de Platão. Este é, claramente, um tema fundamental da filosofia política.

Translation of and Foreword to Charles H. Kahn's "Language and Ontology".

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)

Chemotaxis in bacteria is an excellent model for signal transduction processes. In Agrobacterium tumefaciens, the causative agent of crown gall tumour on wounded plants, it is a vital part of the organism's biology. A chromosomally‐determined chemotaxis system causes the bacterium to be attracted into the rhizosphere by chemoattractants in plant exudates. By interfacing with this system, the multifunctional products of two Tiplasmid encoded genes, virA and virG, allow the sensing of specific wound phenolics such as acetosyringone. This attracts Ti‐plasmid harbouring (...) A. tumefaciens to wound sites, where the higher acetosyringone concentrations lead to virA and virG‐mediated induction of the vir‐genes. The products of the induced genes, act in concert to effect transfer of the T‐DNA to the plant cell. (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.

Charles Darwin (1809–1882) Charles Darwin is primarily known as the architect of the theory of evolution by natural selection. With the publication of On the Origin of Species in 1859, he advanced a view of the development of life on earth that profoundly shaped nearly all biological and much philosophical thought which followed.

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.

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)

What is new in Ch. H. Kahn reinterpretation of Plato's "Cratylus" is the way he considers its main problem: the question of correctness of names. In traditional approach there are two opposite theses: 1) names are conventional; 2) names are regarded as natural. Kahn, however, maintains that Plato is in fact concerned with a quite different pair of questions. The first one is the sign relation of the language and its role in the communication. The other is the sense and (...) the role of the study of names as a means for investigating the nature of things. (shrink)

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)

Landauer's principle, often regarded as the basic principle of the thermodynamics of information processing, holds that any logically irreversible manipulation of information, such as the erasure of a bit or the merging of two computation paths, must be accompanied by a corresponding entropy increase in non-information-bearing degrees of freedom of the information-processing apparatus or its environment. Conversely, it is generally accepted that any logically reversible transformation of information can in principle be accomplished by an appropriate physical mechanism operating in a (...) thermodynamically reversible fashion. These notions have sometimes been criticized either as being false, or as being trivial and obvious, and therefore unhelpful for purposes such as explaining why Maxwell's Demon cannot violate the second law of thermodynamics. Here I attempt to refute some of the arguments against Landauer's principle, while arguing that although in a sense it is indeed a straightforward consequence or restatement of the Second Law, it still has considerable pedagogic and explanatory power, especially in the context of other influential ideas in nineteenth and twentieth century physics. Similar arguments have been given by Jeffrey Bub. (shrink)
