" Because characters and the conception of characters are central to all studies of evolution, and because evolution is the central organizing principle of biology, this book will appeal to a wide cross-section of biologists.

It is nearly universally presumed that redistribution can be carried out effectively only at the national or even global level, because local redistribution will be negated through personal mobility: recipients will move to high-paying jurisdictions while taxpayers will move away from those jurisdictions. To avoid this situation requires redistribution to be concentrated at national and not at local levels. In contrast to this standard line of argument, we explore how redistribution might be carried out more effectively at local levels than (...) at the national level. To explain this reversal from standard analytical implications, we integrate three concepts that are not present in the standard analysis. These concepts are the Samaritan’s dilemma, co-production, and polycentricity. It is interaction among these three concepts that reverses the implications of the standard analysis of redistribution.

This book argues that sociology has lost its ability to provide critical diagnoses of the present human condition because sociology has stopped considering the philosophical requirements of social enquiry. The book attempts to restore that ability by retrieving some of the key questions that sociologists tend to gloss over, inescapability and attainability. The book identifies five key questions in which issues of inescapability and attainability emerge. These are the questions of the certainty of our knowledge, the viability of our politics, (...) the continuity of our selves, the accessibility of the past, and the transparency of the future. The book demonstrates how these questions are addressed in different forms and by different intellectual means during the past 200 years and shows how they persist today. (shrink)

The goal of this paper is to describe the link between financial performance and the level of sustainability. In a novel approach, the paper classifies firms based on past financial success to address a potentially reciprocal relationship. For the groups of better and worse performing firms and for the entire sample, the above link is then tested, also accounting for non-linearity in the relationship. We show that environmental management system (EMS) implementation as a proxy for a firm's sustainability level is (...) only positively associated with the financial performance of financially well-performing firms. Conversely, it has a negative association with the performance of less good firms. We show that this implies that firms cannot change from good to bad performance, and vice versa, solely through the implementation of an EMS, and also that the result remains when introducing non-linearity in the link. Based on this result, we discuss implications for the direction of causality. (shrink)

Historically, one of the most controversial aspects of Darwinian evolution has been the prominent role that randomness and random change play in it. Most biologists agree that mutations in DNA have random effects on fitness. However, fitness is a highly simplified scalar representation of an enormously complex phenotype. Challenges to Darwinian thinking have focused on such complex phenotypes. Whether mutations affect such complex phenotypes randomly is ill understood. Here I discuss three very different classes of well-studied molecular phenotypes in which (...) mutations cause nonrandom changes, based on our current knowledge. What is more, this nonrandomness facilitates evolutionary adaptation. Thus, living beings may translate DNA change into nonrandom phenotypic change that facilitates Darwinian evolution. (shrink)

Background Physician-assisted suicide (PAS) and voluntary euthanasia remain highly debated topics in society, drawing attention due to their ethical, legal, and emotional complexities. Within this debate, the loss of a loved one through suicide may shape the attitudes of survivors, resulting in more or less favorable attitudes towards this topic. Aims This study aims to explore and compare the attitudes towards PAS and voluntary euthanasia in a population of suicide loss survivors and the general population, while also considering socio-demographic factors. (...) Methods A total of 529 participants, 168 of whom were survivors of suicide loss, completed an online questionnaire on their attitudes (NOBAS) and opinions (open response format) towards PAS and voluntary euthanasia, as well as regarding their legalization in Germany. The analysis consisted of both quantitative and qualitative components. Results The entire sample showed positive attitudes towards PAS and voluntary euthanasia in terminally ill persons. Participants were more divided in their attitudes towards PAS in the case of a mental health disorder. Individuals without experienced suicide loss were more liberal regarding legalization in Germany and were more likely to understand the wish for PAS. Survivors of suicide loss were mainly concerned about the consequences for relatives. However, differences between both groups are small. Discussion The experience of a loss by suicide influences attitudes towards PAS and voluntary euthanasia. Both groups showed an accepting attitude towards PAS and voluntary euthanasia, but also expressed concerns and fears regarding easy accessibility and consequences for grieving relatives. (shrink)

This article interprets Józef Maria Hoëné Wronski’s (1776–1853) use of actual infinities in his mathematical work. The interpretation places this usage, which undermined Wronski’s acceptance as a mathematician, in his contemporary mathematical and philosophical context and in the context of his own sociopolitical-philosophical project.

This paper argues that social representations cannot be used as independent variables in causal explanations of social behaviour. It is shown that the structure of investigations often follows a causally explanatory design despite explicit statements to the contrary by the researchers. This fact is analyzed with three investigations. It is argued that verbal data used to assess the contents of a representation as independent variable are logically equivalent to data obtained from the “dependent” overt behaviour. Therefore these two kinds of (...) data must be seen as two illustrations of the same representational contents. The researchers’preference for using verbal data to assess the independent variable and the tendency to introduce a causal relationship between representation and behaviour is shown to result from misplacing folk-beliefs. Folk-beliefs about intentional causality, it is shown, pertain to the same level as other beliefs about the world on the part of the subjects. Hence they are part of the folk-representation itself and must be treated as such; their use in scientific accounts of the belief-action relationship is not implied by data on rational belief systems. It is suggested to conceptualize social representations as integral units of beliefs and action which may be used to explain causally subsequent contingent social events. The function of folk-beliefs in intentional causality for the self-concept of rational people and for social accountability is discussed. (shrink)

During the past two centuries, and in particular during the inter-war period, American ways of living and of thinking have become one principal object of European reflections on modernity. This essay explores some of the ways in which the rejection or affirmation of modernity in Europe has been channelled through observations on America. It is argued that the variety of European ways of looking at America also demonstrates the range of forms available to social theory for thinking the social world (...) under conditions of modernity and that this European debate provided some seeds for the current discussion about `multiple modernities'.

We generalize Frécon’s construction of the inevitable radical to groups in stable and even simple theories.

We define an $\mathfrak{R}$-group to be a stable group with the property that a generic element can only be algebraic over a generic. We then derive some corollaries for $\mathfrak{R}$-groups and fields, and prove a decomposition theorem and a field theorem. As a nonsuperstable example, we prove that small stable groups are $\mathfrak{R}$-groups.

By advocating an enlightened method of theorizing committed to thinking in terms of a system of differences, Luhmann has contributed to the development of sociology in a manner that cannot be praised enough. Nonetheless, he does not succeed in giving an account of his own position that satisfies the very logical preconditions that he himself has formulated for it. Instead, his systems theory paradigm of sociology is based on metaphysical premises characteristic of the identity-logical thought of "Old Europe." In fact, (...) the only way to make Luh mann's approach truly comprehensible is to reconstruct it as a new version of Hegel's dialectic. (shrink)

Evidentiary propositions E 1 and E 2, each p-positively relevant to some hypothesis H, are mutually corroborating if p > p, i = 1, 2. Failures of such mutual corroboration are instances of what may be called the corroboration paradox. This paper assesses two rather different analyses of the corroboration paradox due, respectively, to John Pollock and Jonathan Cohen. Pollock invokes a particular embodiment of the principle of insufficient reason to argue that instances of the corroboration paradox are of negligible (...) probability, and that it is therefore defeasibly reasonable to assume that items of evidence positively relevant to some hypothesis are mutually corroborating. Taking a different approach, Cohen seeks to identify supplementary conditions that are sufficient to ensure that such items of evidence will be mutually corroborating, and claims to have identified conditions which account for most cases of mutual corroboration. Combining a proposed common framework for the general study of paradoxes of positive relevance with a simulation experiment, we conclude that neither Pollock’s nor Cohen’s claims stand up to detailed scrutiny. I am quite prepared to be told…”oh, that is an extreme case: it could never really happen!” Now I have observed that this answer is always given instantly, with perfect confidence, and without any examination of the proposed case. It must therefore rest on some general principle: the mental process being something like this—“I have formed a theory. This case contradicts my theory. Therefore, this is an extreme case, and would never occur in practice.”Rev. Charles L. Dodgson. (shrink)

Game theory is often used to explain behavior. Such explanations often proceed by demonstrating that the behavior in question is a Nash equilibrium. Agents are in Nash equilibrium if each agent’s strategy maximizes her payoff given her opponents’ strategies. Nash equilibriums are fundamentally static, but it is usually assumed that equilibriums will be the outcome of a dynamic process of learning or evolution. This article demonstrates that, even in the most simple setting, this need not be true. In two-strategy games (...) with just a single equilibrium, a family of imitative learning dynamics does not lead to equilibrium. (shrink)

This paper presents the 'rationality-of-ends/market-structure grid'. With this grid, the article contrasts, in economic terms, different approaches to business ethics and addresses the question how far and what type of business ethics is feasible. Four basic scenarios for business ethics are outlined that imply different conceptualizations of business ethics. The grid interrelates a rationality-of-ends dimension with a market-structure dimension. The rationality-of-ends dimension ranges from opportunism and self-interested egoism to self-interested altruism and ultimately to authentic altruism. The market-structure dimension ranges from (...) perfect competition/no information problems/perfectly dispersed market power to imperfect competition/high information problems/concentrated power. Rather than presenting economic, legal, ethical and discretionary issues in a hierarchical fashion, the grid interrelates these issues. Conclusions are spelled out regarding the empirical observance of business ethics and the programmatic, 'theoretical' positions that are behind empirical observations. Practical implications for managers and public policy makers are outlined. (shrink)

The thesis that `1968' resulted in the rise of the individual, on the one hand, and the end of politics, on the other, is critically discussed by interpreting the events of 1968 as a project of emancipation and by distinguishing between the individual and the collective aspects of emancipation.

Hoy en día vivimos aún con el estereotipo de las dos culturas, con la idea de una cierta incomunicabilidad entre ciencias y humanidades, en términos más generales: entre la esfera de la ciencia y la de la cultura. Este artículo presenta una visión filosófica de la relación entre cultura y ciencia más allá de la tópica dicotomía, sosteniendo en cambio un enfoque en el que se concibe la ciencia como fenómeno cultural. Un recorrido histórico-sistemático por algunos hitos de la filosofía (...) de la cultura y la filosofía de la ciencia muestra cómo las dos se compenetran entre sí y se influyen mutuamente. Poner el foco en las convergencias entre ambas permite identificar una serie de preocupaciones y retos compartidos que conciernen al campo de la epistemología en su conjunto: afrontar la complejidad de la condición epistémica y la vulnerabilidad cognitiva del ser humano; hacer frente a las posiciones más extremas tanto del relativismo como del fundamentalismo; y desarrollar un concepto de responsabilidad epistémica en los distintos ámbitos de conocimiento para contrarrestar la cultura de desconfianza y la percepción de nuestra época como era de la posverdad.

We define the notion of generic for an arbitrary subgroup H of a stable group, and show that H has a definable hull with the same generic properties. We then apply this to the theory of stable fields.

It is shown that the Fisher smoking problem and Newcomb's problem are decisiontheoretically identical, each having at its core an identical case of Simpson's paradox for certain probabilities. From this perspective, incorrect solutions to these problems arise from treating them as cases of decisionmaking under risk, while adopting certain global empirical conditional probabilities as the relevant subjective probabihties. The most natural correct solutions employ the methodology of decisionmaking under uncertainty with lottery acts, with certain local empirical conditional probabilities adopted as (...) the relevant subjective probabilities.

Recombination is often considered a disruptive force for well‐adapted phenotypes, but recent evidence suggests that this cost of recombination can be small. A key benefit of recombination is that it can help create proteins and regulatory circuits with novel and useful phenotypes more efficiently than point mutation. Its effectiveness stems from the large‐scale reorganization of genotypes that it causes, which can help explore far‐flung regions in genotype space. Recent work on complex phenotypes in model gene regulatory circuits and proteins shows (...) that the disruptive effects of recombination can be very mild compared to the effects of mutation. Recombination thus can have great benefits at a modest cost, but we do not understand the reasons well. A better understanding might shed light on the evolution of recombination and help improve evolutionary strategies in biochemical engineering. (shrink)
