A discussion of egoism and altruism as related both to ethical theory and moral psychology. Williams considers and rejects various arguments for and against the existence of egoistic motives and the rationality of someone motivated by self-interest. He ultimately attempts to give a more Humean defense of altruism, as opposed to the more Kantian defenses found in Thomas Nagel, for example.

Let $D_{tt} $ denote the set of truth-table degrees. A bijection π: $D_{tt} \to \,D_{tt} $ is an automorphism if for all truth-table degrees x and y we have $ \leqslant _{tt} \,y\, \Leftrightarrow \,\pi (x)\, \leqslant _{tt} \,\pi (y)$ . We say an automorphism π is fixed on a cone if there is a degree b such that for all $x \geqslant _{tt} b$ we have π(x) = x. We first prove that for every 2-generic real X we have (...) X' $X' \le _{tt} \,X\, \oplus \,0'$ . We next prove that for every real $X \ge _{tt} \,0'$ there is a real Y such that $Y \oplus 0{\text{'}}\, \equiv _{tt} \,Y{\text{'}} \equiv _{tt} \,X$ . Finally, we use this to demonstrate that every automorphism of the truth-table degrees is fixed on a cone. (shrink)

Anderson and Csima :245–264, 2014) defined a jump operator, the bounded jump, with respect to bounded Turing reducibility. They showed that the bounded jump is closely related to the Ershov hierarchy and that it satisfies an analogue of Shoenfield jump inversion. We show that there are high bounded low sets and low bounded high sets. Thus, the information coded in the bounded jump is quite different from that of the standard jump. We also consider whether the analogue of the Jump (...)

We say that a real X is n-generic relative to a perfect tree T if X is a path through T and for all $\Sigma _{n}^{0}(T)$ sets S, there exists a number k such that either X|k ∈ S or for all σ ∈ T extending X|k we have σ ∉ S. A real X is n-generic relative to some perfect tree if there exists such a T. We first show that for every number n all but countably many reals (...) are n-generic relative to some perfect tree. Second, we show that proving this statement requires ZFC− + "∃ infinitely many iterates of the power set of ω". Third, we prove that every finite iterate of the hyperjump. ${\cal O}^{(n)}$ , is not 2-generic relative to any perfect tree and for every ordinal α below the least λ such that supβ<i (βth admissible) = λ, the iterated hyperjump ${\cal O}^{(\alpha)}$ is not 5-generic relative to any perfect tree. Finally, we demonstrate some necessary conditions for reals to be 1-generic relative to some perfect tree. (shrink)

I present the arguments of Gabriel Marcel which are intended to overcome the potentially negative impact of technology on the human. Marcel is concerned with forgetting or rejecting human nature. His perspective is metaphysical. He is concerned with the attitude of the "mere technician" who is so immersed in technology that the values which promote him as an authentic person with human dignity are discredited, omitted, denied, minimized, overshadowed, or displaced. He reviews the various losses in ontological values which curtail (...) the full realization of the human person in his dignity. The impact of technology leads too often to a loss of the sense of the mystery of being and self, authenticity and integrity, the concrete and the existential, truth and dialogue, freedom and lover, humanity and community, fidelity and creativity, the natural and the transcendent, commitment and virtue, respect of the self and responsiveness to others, and especially of the spiritual and the sacred. Thus, the task of the philosopher is to be a watchman, un veilleur, on the alert for a hopeful resolution of the human predicament. (shrink)

A very readable, scholarly, and provocative book by Louis Dupré gives a new interpretation and meaning to the passage to modernity. Dupre gives a fascinating hermeneutic analysis of the creative revolution achieved by the early and late humanists and thinkers of the Renaissance in rethinking reality in terms beyond the ancient and medieval ontotheological synthesis of God, the human, and the Cosmos. The book analyzes how the break leading into modernity took place at that time and prior to the second (...) modern revolution--the Enlightenment, when the transcendent component was disowned in favor of the human subject. Later, both were deprioritized in favor of the cosmos. (shrink)

In Nietzsche's Psychology of Ressentiment, Guy Elgat develops an interpretation of some of the central themes of Nietzsche's GM, which is one of his most systematic works and a pivotal part of his critique of the modern moral outlook that grew out of Christianity. Elgat's original approach is framed by two fundamental ideas: first, Nietzsche takes the concept of "moral justice" to be central to the morality he sets out to criticize; second, Nietzsche's suspicion toward moral justice is rooted in (...) its association with the affect of ressentiment. Thus, Elgat notes that ressentiment is frequently supposed either to express a sense of justice, or to... (shrink)

Inborn errors of vitamin B12 (cobalamin) metabolism are associated with homocystinuria and methylmalonic aciduria, either alone or in combination. A number of these disorders have provided the first evidence for the existence of important steps in the transport or metabolism of cobalamin in eukaryotic cells. Eight complementation classes have been defined on the basis of somatic cell hybridization studies. Although the majority of patients present in infancy or early childhood, some are not diagnosed until adolescence or later. For some of (...) these disorders, prenatal diagnosis and therapy with cobalamin during pregnancy has been attempted. Although only males have been described with cblE disease, all of these disorders are presumed to be autosomal recessive in inheritance. The clinical and laboratory aspects of the different complementation classes (cblA–cblG) are reviewed here. (shrink)

This article attempts an organological and pharmacological re-interpretation of the later Heidegger’s understanding of modern technology as a provocative mode of revealing of beings, in particular of its central notions of Gestell [enframing] Gefahr [danger], Kehre [turning] and Ereignis [event]. Although these notions in principle allow us to think what is at stake currently in the Anthropocene as the age of total automation, generalized toxicity of the technical milieu and post-truth calling for a radical bifurcation, they need to be reframed (...) and re-imagined in terms of the process of exosomatization issuing from humanity’s original and necessary default of origin and situated within the perspective of entropy and negentropy, both unthought by Heidegger. Only thus will it become possible to really think and take care of what Heidegger called the danger of technology and its turning into the event as the destiny of enframing. This also requires a rethinking of Aristotle’s theory of four causes as it is invoked by Heidegger in his analysis of technology, in particular the efficient and final causes, in terms of what Deleuze called quasi-causality, here understood as the need and the obligation for mortals to make their fault come true, i.e., to make it truly happen or make it advene in truth, out of the experience of the danger as the ordeal of the necessary default. Thus becoming the anti-anthropic cause of anthropic toxicity, humans would restore final causality as quasi-causality and inaugurate, as neganthropos, the bifurcation into the Neganthropocene.

Nationalism is one of modern history’s great surprises. How is it that the nation, a relatively old form of community, has risen to such prominence in an era so strongly identified with the individual? Bernard Yack argues that it is the inadequacy of our understanding of community—and especially the moral psychology that animates it—that has made this question so difficult to answer. Yack develops a broader and more flexible theory of community and shows how to use it in the (...) study of nations and nationalism. What makes nationalism such a powerful and morally problematic force in our lives is the interplay of old feelings of communal loyalty and relatively new beliefs about popular sovereignty. By uncovering this fraught relationship, Yack moves our understanding of nationalism beyond the oft-rehearsed debate between primordialists and modernists, those who exaggerate our loss of individuality and those who underestimate the depth of communal attachments. A brilliant and compelling book, _Nationalism and the Moral Psychology of Community_ sets out a revisionist conception of nationalism that cannot be ignored. (shrink)

This new translation of four revised radio interviews, conducted in December 2002 at France Culture with Elie During, is the best introduction to Stiegler's Time and Technics series. This collection includes a new interview conducted specially for this volume and an interview with Artpress from 2001. In Philosophising By Accident, Stiegler introduces some of the key arguments about the technical constitution of the human and its relation to politics, aesthetics and economics. He reads philosophical texts from the perspective of his (...) controversial thesis about the three types of memory and speaks about concepts central to his later works, such as synchrony/diachrony, grammatisation and the industrial temporal object.

Individuals regaining reliable day-to-day walking function after incomplete spinal cord injury report persisting unsteadiness when confronted with walking challenges. However, quantifiable measures of walking capacity lack the sensitivity to reveal underlying impairments of supra-spinal locomotor control. This study investigates the relationship between intramuscular coherence and corticospinal dynamic balance control during a visually guided Target walking treadmill task. In thirteen individuals with iSCI and 24 controls, intramuscular coherence and cumulant densities were estimated from pairs of Tibialis anterior surface EMG recordings during (...) normal treadmill walking and a Target walking task. The approximate center of mass was calculated from pelvis markers. Spearman rank correlations were performed to evaluate the relationship between intramuscular coherence, clinical parameters, and center of mass parameters. In controls, we found that the Target walking task results in increased high-frequency intramuscular coherence, which negatively related to changes in the center of mass movement, whereas this modulation was largely reduced in individuals with iSCI. The impaired modulation of high-frequency intramuscular coherence during the Target walking task correlated with neurophysiological and functional readouts, such as motor-evoked potential amplitude and outdoor mobility score, as well as center of mass trajectory length. The Target walking effect, the difference between Target and Normal walking intramuscular coherence, was significantly higher in controls than in individuals with iSCI [F = 13.042, p < 0.001]. Intramuscular coherence obtained during challenging walking in individuals with iSCI may provide information on corticospinal gait control. The relationships between biomechanics, clinical scores, and neurophysiology suggest that intramuscular coherence assessed during challenging tasks may be meaningful for understanding impaired supra-spinal control in individuals with iSCI.

Abstract The idea of a purely civic nationalism has attracted Western scholars, most of whom rightly disdain the myths that sustain ethnonationalist theories of political community. Civic nationalism is particularly attractive to many Americans, whose peculiar national heritage encourages the delusion that their mutual association is based solely on consciously chosen principles. But this idea misrepresents political reality as surely as the ethnonationalist myths it is designed to combat. And propagating a new political myth is an especially inappropriate way of (...) defending the legacy of Enlightenment liberalism from the dangers posed by the growth of nationalist political passions.

This essay asks why Aristotle, certainly no friend to unlimited democracy, seems so much more comfortable with unconstrained rhetoric in political deliberation than current defenders of deliberative democracy. It answers this question by reconstructing and defending a distinctly Aristotelian understanding of political deliberation, one that can be pieced together out of a series of separate arguments made in the Rhetoric, the Politics, and the Nicomachean Ethics.
