All disciplines must define their basic units and core processes. In evolutionary biology, the core process is natural selection and the basic unit of selection and adaptation is the individual. To operationalize the theory of natural selection we must count individuals, as they are the bearers of fitness. While canonical individuals have often been taken to be multicellular organisms, the hierarchy of life shows that new kinds of individuals have evolved. A variety of criteria have been used to define biological (...) individuality. Some criteria rely on the presence/absence of a particular property while others advocate an approach that reflects the process of natural selection. The plethora of approaches to classifying individuality has resulted in confusion regarding how to study individuality in a given taxon. (shrink)

Neo-Fregeans such as Bob Hale and Crispin Wright seek a foundation of mathematics based on abstraction principles. These are sentences involving a relation called the abstraction relation. It is usually assumed that abstraction relations must be equivalence relations, so reflexive, symmetric and transitive. In this article I argue that abstraction relations need not be reflexive. I furthermore give an application of non-reflexive abstraction relations to restricted abstraction principles.

Harold Hodes in [1] introduces an extension of first-order modal logic featuring a backtracking operator, and provides a possible worlds semantics, according to which the operator is a kind of device for ‘world travel’; he does not provide a proof theory. In this paper, I provide a natural deduction system for modal logic featuring this operator, and argue that the system can be motivated in terms of a reading of the backtracking operator whereby it serves to indicate modal scope. I (...) prove soundness and completeness theorems with respect to Hodes’ semantics, as well as semantics with fewer restrictions on the accessibility relation. (shrink)

Neo-Fregean approaches to set theory, following Frege, have it that sets are the extensions of concepts, where concepts are the values of second-order variables. The idea is that, given a second-order entity $X$, there may be an object $\varepsilon X$, which is the extension of X. Other writers have also claimed a similar relationship between second-order logic and set theory, where sets arise from pluralities. This paper considers two interpretations of second-order logic—as being either extensional or intensional—and whether either is (...) more appropriate for this approach to the foundations of set theory. Although there seems to be a case for the extensional interpretation resulting from modal considerations, I show how there is no obstacle to starting with an intensional second-order logic. I do so by showing how the $\varepsilon$ operator can have the effect of “extensionalizing” intensional second-order entities. (shrink)

Recent work in social psychology suggests that people harbor “implicit race biases,” biases which can be unconscious or uncontrollable. Because awareness and control have traditionally been deemed necessary for the ascription of moral responsibility, implicit biases present a unique challenge: do we pardon discrimination based on implicit biases because of its unintentional nature, or do we punish discrimination regardless of how it comes about? The present experiments investigated the impact such theories have upon moral judgments about racial discrimination. The results (...) show that different theories differ in their impact on moral judgments: when implicit biases are defined as unconscious, people hold the biased agent less morally responsible than when these biases are defined as automatic (i.e., difficult to control), or when no theory of implicit bias is provided.

Based on a critical interpretative review of existing qualitative research investigating accounts of ‘lived experience’ of surrogates and intended parents from a relational perspective, this article proposes a typology of surrogacy arrangements. The review is based on the analysis of 39 articles, which belong to a range of different disciplines (mostly sociology, social psychology, anthropology, ethnology, and gender studies). The number of interviews in each study range from as few as seven to over one hundred. Countries covered include Australia, Canada, (...) Greece, India, Iran, Israel, Italy, Mexico, Norway, Russia, Sweden, UK, Ukraine, and the USA. Most studies focus only on surrogacy practices in one country (although often with intended parents from other countries), and some include several countries (e.g. interviewees from several countries or fieldwork in different field-sites). The proposed typology goes beyond the division between altruistic versus commercial, and traditional versus gestational surrogacy, in order to inform further research and to contribute to bioethical and policy debates on surrogacy in a transnational context. Four types of relations are identifiable: open, restricted, structured, and enmeshed. The criteria which influence these relationships are: the frequency and character of contact pre- and post-birth; expectations of both parties; the type of exchange involved in surrogacy arrangements; and cultural, legal, and economic contexts. The theoretical contribution of the article is to further the development of a relational justice approach to surrogacy. (shrink)

The financial turmoil of the past several years has caused many to question the integrity, stability, and very purpose of financial systems which, in today’s world, represent a unique blend of primarily capitalism but also aspects of socialism and collectivism as well. A key factor contributing to this sustained period of economic upheaval has been the uncertainty surrounding capital markets – the fuel that powers all modern economies. Capital markets have, in the minds of many, come to represent the embodiment (...) of greed, unrestrained egoism, and exploitation of the vulnerable – conceptions at complete odds with the central values of social justice as set forth in both Christian and Jewish primary sources: caring for the poor, protecting the weak, and the promotion of justice. -/- In this paper I argue that capital markets, rather than being a means for the powerful to exploit the weak, have in fact become a force for social good in the aggregate. Indeed capital markets are, in fact, a social contract and as such must be governed by a set of normative ethical principles – both self imposed, and imposed by government regulation. I explore the ethical difficulties that have led to the systemic problems and market failures that lead to not only this current financial crisis, but literally all financial crises over the past eight hundred years. Capital markets, left to their own devices and without both self and governmental oversight, quickly become hotbeds of manipulation and exploitation. In order for markets to function properly, principles of basic fairness must become normative. It is when capital markets become unfair and unjust, that they fail. Thus, these markets must be structured in such a way as to 1) promote Rawl’s “Justice as Fairness” principle and 2) align the interests of market participants to produce universally beneficial market efficiency and stability. -/- Finally, I propose concrete ways in which the power of capital markets may be harnessed to promote the central moral values of Christian tradition and be used by people of faith to promote the ideals of social justice.

Kant and the Concept of Community, edited by Charlton Payne and Lucas Thorpe, gathers together some of the best known figures in contemporary Kant scholarship. This fine collection traces Kant’s concept of community from its Precritical roots to its role in The Critique of Pure Reason, before going on to investigate the subsequent transformations it would undergo in Kant’s later works on ethics, religion, history, politics, and aesthetics. With very few exceptions, all of the essays in this collection are (...) interesting and informative, with signature pieces by Béatrice Longuenesse, Paul Guyer, Allen Wood, Onora O’Neill, and Susan Shell. This is a highly recommended collection suitable for advanced undergraduates, graduate students, and professionals. (shrink)
