The Drosophila anterior‐posterior pattern genes of the terminal class, particularly the tailless gene, affect structures derived from the acron and the tail region of the embryo. These domains correspond in position and function to asegmental domains at the termini of annelids and more primitive insect embryos. This suggests that terminal genes in Drosophila may have originated in an ancestor common to both annelids and arthropods, and thus that the specification of termini in these metameric organisms is an ancient, evolutionarily conserved (...) process.

In environmental ethics, there has been too little attention to the question of why changes in environmental beliefs do not simply result in changes in behavior, given that this gap between belief and behavior is widespread. In this essay, I argue that two forms of inaction that exhibit this gap can be helpfully analyzed by reading them in terms of a Lutheran account of sin. To make the argument, I distinguish seven forms of and reasons for inaction, from which I (...) pull out two “privileged” forms of inaction that characterize people who could act and yet do not. Using psychological and sociological research, I interpret these two forms of inaction as, on the one hand, people’s attempts at securing righteousness and, on the other hand, people’s terrorized consciences in response to the complexity and gravity of climate change. I end suggesting a turn to justification within Christian environmental ethics. (shrink)

In much environmentally concerned literature, there is a burgeoning concern for the status and sustainability of human hope. Within Christian circles, this attention has often taken the form of eschatological reflection. While there is important warrant for attention to eschatology in Christian examinations of hope, I claim that to move so quickly from hope to eschatology is to confuse a species of Christian hope for a definition of hope itself; as such, it is important for theological ethicists to examine hope (...) also from the experiential perspective of the human hoper. In particular, this is important today given the shortcomings of an eschatological focus in addressing anxieties arising due to the environmental crisis. Through examining hope as a fallible human activity, one can come to better understand hope's importance to human life, its profound ambiguity, and the potential threat that the environmental crisis poses to it.

We prove a generalization of Alex Heller's existence theorem for recursion categories; this generalization was suggested by work of Di Paola and Montagna on syntactic P-recursion categories arising from consistent extensions of Peano Arithmetic, and by the examples of recursion categories of coalgebras. Let B=BX be a uniformly generated isotypical B#-subcategory of an iteration category C, where X is an isotypical object of C. We give calculations for the existence of a weak Turing morphism in the Turing completion Tur of (...) B when C is separated; i.e., when connected domains in C are jointly epimorphic. Our proof generalizes as follows. Let D be a separated iteration category and let L : C → D be an iteration functor; i.e., a functor which preserves domains, coproducts, zero morphisms and the iteration operator; it is crucial for the generalization that an iteration functor need not preserve products. If L is faithful, then Tur is a recursion category. (shrink)

In this paper, I would like to investigate how Gadamer explores the hermeneutic potential of Kant’s aesthetic theory in the third Critique with regard to the notion of imagination. For the first time, by making some references, Gadamer discussed the question of imagination in his Truth and Method of 1960, and we can read as a further substantial contribution his essay entitled Anschauung und Anschaulichkeit (Intuition and Intuitiveness) published in 1980. Although Gadamer’s approach was influenced by some Heideggerian impulses, he (...) offered another alternative that is completely different from Heidegger’s one. I shall argue that even if the question of imagination is not so much stressed by Gadamer, it proves important to the development and ontological basis of the Gadamerian hermeneutics in Wahrheit und Methode. My hypothesis is that through the themes of intuition and education (Bildung), the imagination is concerned with the human understanding and our interpreting work, thus, its significance transcends the scope of aesthetics.

The purpose of our contribution in this paper is to provide an overview of development of Heidegger’s account of imagination with a special focus to the affinity between phenomenology and psychology. (I.) Firstly, we reconstruct how – by his reading Husserl and Aristotle – the early Heidegger got to know the function of imagination as it can open the realm of the things themselves. (II.) Secondly, we investigate that in his Kant-book, Heidegger gave up his plan to further think the (...) viewpoints envisioned by Husserl and the Neo-Kantians, and he entirely transformed his previous concept of imagination by the chapter on Schematism. Ourcore thesis is that Heidegger’s account of imagination is concerned with the emergence of schemes of our thinking, that is to say, Heidegger went beyond the psychological Kant-interpretation, and at the same time he turned to discover the field of phenomenological unconscious.

Since it was first published, Quantum Field Theory in a Nutshell has quickly established itself as the most accessible and comprehensive introduction to this profound and deeply fascinating area of theoretical physics. Now in this fully revised and expanded edition, A. Zee covers the latest advances while providing a solid conceptual foundation for students to build on, making this the most up-to-date and modern textbook on quantum field theory available. -/- This expanded edition features several additional chapters, as well as (...) an entirely new section describing recent developments in quantum field theory such as gravitational waves, the helicity spinor formalism, on-shell gluon scattering, recursion relations for amplitudes with complex momenta, and the hidden connection between Yang-Mills theory and Einstein gravity. Zee also provides added exercises, explanations, and examples, as well as detailed appendices, solutions to selected exercises, and suggestions for further reading. (shrink)

Exploring history pertinent to evolutionary developmental biology (hereafter, Evo-devo) is an exciting prospect given its current status as a cutting-edge field of research. The first and obvious question concerns where to begin searching for materials and sources. Since this new discipline adopts a moniker that intentionally juxtaposes ‘evolution’ and development’, individuals, disciplines, and institutional contexts relevant to the history of evolutionary studies and investigations of ontogeny prompt themselves. Each of these topics has received attention from historians and thus there is (...) both primary and secondary material from which to draw. For example, many historians have documented the historical trajectories of genetics and embryology, their split, and various relations (or lack thereof), especially in the first three decades of the 20th century.

Aristotle's definition of the soul should be interpreted as: 'the soul is the entelechy of a natural body that serves as its instrument'.

Purpose: To examine the role of reductionism in the theoretical development of modern physics -- more specifically, in the quest for a complete unification of physical theory -- from the perspective of radical constructivism (RC). Approach: Some central features of the impact of RC on philosophy of physics are pointed out: its position of scientific relativism, with important implications for the validation of scientific propositions; and the notion of sharing constructed knowledge among individual knowers and its consequences for science teaching. (...) The issue of reductionism is then discussed with regard to (a) the hierarchical explanatory ordering of physical phenomena; (b) the idea of a "theory of everything" (TOE); and (c) some of its implications for the methodology and sociology of science. Findings: It is argued that the ontological status of the hierarchical structuring inherent in the sought-after TOE will depend on the individual knower's epistemic position concerning the notion of truth in science. In the relativist epistemology of RC, any true/false dichotomy of theories is without meaning. A hierarchical ordering is just one of many possible strategies that may be chosen for the construction of physical theories; and such a strategy may then be considered successful only to the extent that it yields a theory that is viable. Implications: The paper serves as an illustration of the impact of RC on the ongoing search in physics for a "final theory.". (shrink)

In lieu of an abstract, here is a brief excerpt of the content:PrefaceScott Paeth and Kevin CarnahanThis issue of the Journal of the Society of Christian Ethics is organized around the theme of structural evil. Each of the essays deals with some dimension of the problem of how we can conceive of evil beyond the question of simple human volition, and understand it as embedded in the institutions and cultural assumptions that we often take for granted as societal givens.Cristina Traina's (...) presidential address, "This Is the Year," takes as its starting point the aftermath of the 2016 US presidential election, arguing that it exposes the way in which liberal narratives of progress have failed to address the deeply embedded structural evil within American society. She argues that this political moment provides an opportunity for liberals to engage in a critical self-examination with respect to their complicity in these structures by embracing a form of "utopian praxis."Ryan Darr's essay considers the intersection of structural evil and individual responsibility, arguing, on the one hand, for a distinction between sin and moral wrongdoing and, on the other, for an approach to both concepts that is social in form. Esther Reed's essay, meanwhile, offers an analysis of responsibility in light of the question of structural evil, using the theology of Dietrich Bonhoeffer to aid in understanding the connection between individual responsibility and distant harm.David Cloutier continues the examination of the tension between individual agency and structural evil in his critique of the "neo-Franciscan" and "Junian" approaches to issues of violence and racism, arguing that a "critical realist" approach to structural evil provides greater resources for Christian ethics.Elizabeth Sweeny Block offers a different approach to the question in her consideration of the role of conscience in grappling with crises on a global scale, such as climate change and the Zika virus. She contrasts the "reflexive conscience" predominant in Christian ethics with a model of "engaged conscience," which may provide a better approach to large-scale structural evil and its consequences.Stewart Clem uses Thomas Aquinas's conception of virtue to understand the problems inherent in striving for moral clarity in a "post-truth" context. In [End Page vii] light of Harry Frankfurt's philosophical analysis of the concept of "bullshit," he argues that Christian ethics needs to develop a way of speaking about truth as a virtue in order to respond to the structural problem of truth indifference in contemporary political discourse.Looking at the problem from a different perspective, Christopher Jones and Conor Kelly examine the sin of sloth from a structural point of view. Critiquing individualist conceptions of the idea, they make the case for retrieving the classical definition of sloth as a vice against charity and consider how sloth can be overcome through a reinvigoration of forms of civic virtue.Another dimension of structural evil is considered by Ryan Newson in his examination of the role that Confederate monuments play in the American South. For many, they stand as a symbol of the glorification of evil that should be removed, but Newson suggests that there may be reasons to keep at least some of these monuments as reminders of the failure of justice and the judgment of God.Wonchul Shin and Elizabeth Bounds consider these questions from the perspective of how "ordinary" experiences of moral harm need to be analyzed as dimensions of structural evil, and they call for an examination of structural responsibility and the ethics of repair as a means of addressing these questions.Finally, Willa Swenson-Lengyel looks at the connection between structural evil and environmental ethics, arguing that the "moral paralysis" often experienced in light of the ecological crisis exposes certain forms of privilege that need to be addressed from the perspective of Christian ethics. In many ways, she argues, privileged inaction can be a manifestation of "works righteousness" that can be addressed through a Lutheran conception of the doctrine of justification.________This year the JSCE is retiring the demographic survey that has been used since 2008 and adopting a new demographic survey.
