Mutualisms present a challenge for evolutionary theory. How is cooperation maintained in the face of selection for selfishness and cheating? Both theory and data suggest that partner choice, where one species preferentially directs aid to the more cooperative members of the other species, is central to cooperation in many mutualisms. However, the theory has only so far considered the evolutionary effects of partner choice on one of the species in a mutualism in isolation. Here, we investigate the co-evolution of cooperation and choice in a choosy host and its symbiont. Our model reveals that even though choice and cooperation may be initially selected, it will often be unstable. This is because choice reduces variation in the symbiont and, therefore, tends to remove the selective incentive for its own maintenance (a scenario paralleled in the lek paradox in female choice and policing in within-species cooperation). However, we also show that when variability is reintroduced into symbionts each generation, in the form of less cooperative individuals, choice is maintained. This suggests that the presence of cheaters and cheater species in many mutualisms is central to the maintenance of partner choice and, paradoxically, cooperation itself.

The Relationship

AbstractThe effects of partner choice have been documented in a large number of biological systems such as sexual markets, inter-specific mutualisms, or human cooperation. By contrast, this mechanism has never been demonstrated in a large number of intra-specific interactions in non-human animals such as collective hunts, although one would expect it to play a role as well. Here we use individual-based simulations to solve this apparent paradox. We show that the conditions for partner choice to operate are in fact restrictive. They entail that individuals can compare social opportunities and choose the best. The challenge is that social opportunities are often rare because they necessitate the co-occurrence of (i) at least one available partner, and (ii) a resource to exploit together with this partner. This has three consequences. Firstly, partner choice cannot lead to the evolution of cooperation when resources are scarce, which explains that this mechanism could never be observed in many cases of intra-specific cooperation in animals. On the other hand, partner choice can operate when partners constitute in themselves a resource, which is the case in sexual inter-actions and inter-specific mutualisms. Lastly, partner choice can lead to the evolution of cooperation when individuals are highly efficient at finding resources in their environment, which sheds light on the relationship between cognitive abilities and cooperation, in particular in the human species.

The Relationship

This article reads between two recent explorations of the relationship between religion, chaos, and the monstrous: Catherine Keller’s Face of the Deep and Author's Religion and Its Monsters. Both are oriented toward the edge of chaos and order; both see the primordial and chaotic as generative; both pursue monstrous mythological figures as divine personifications of primordial chaos; both find a deep theological ambivalences in Christian and Jewish tradition with regard to the monstrous, chaotic divine; both are critical of theological and cultural tendencies to demonize chaos and the monstrous; and finally, both read the divine speech from the whirlwind in the book of Job as a revelation of divine chaos. But whereas one sees it as a call for laughter, a chaotic life-affirming laughter with Leviathan in the face of the deep, the other sees it as an incarnation of theological horror, leaving Job and the reader overwhelmed and out-monstered by God. Must it be one way or the other? Can laughter and horror coincide in the face of the deep?

In this article, we explore the debates surrounding the proposed canonization of Archbishop Oscar Romero, an outspoken defender of human rights and the poor during the civil war in El Salvador, who was assassinated in March 1980 by paramilitary death squads while saying Mass. More specifically, we examine the tension between, on the one hand, local and popular understandings of Romero’s life and legacy and, on the other hand, transnational and institutional interpretations. We argue that the reluctance of the Vatican to advance Romero’s canonization process has to do with the need to domesticate and “privatize” his image. This depoliticization of Romero’s work and teachings is a part of a larger agenda of neo-Romanization, an attempt by the Holy See to redeploy a post-colonial and transnational Catholic regime in the face of the crisis of modernity and the advent of postmodern relativism. This redeployment is based on the control of local religious expressions, particularly those that advocate for a more participatory church, which have proliferated with contemporary globalization

This article is devoted to the insufficiently known topic of the disease and death of Y. F. Samarin, a great Russian philosopher, ascetic and warrior, politician and scientist. On the basis of the extensive archival materials the author of the article presents the events panorama that allows to reconstruct certain fragments of Samarin’s life. According to the author, the strongest aspects of Samarin’s personality, supported by his belief in bodily resurrection, were revealed in the face of bodily affliction and death. His love for congenial people, relatives, and Russia dominated all the other feelings of the philosopher both during his life and at the time of his departure. The article shows that something mysterious and undisclosed still remains in Samarin s death.

The Continuum

Abstract The five factor trait of conscientiousnessis a supertrait, denoting on one hand a pattern of excessive labor, rigidity, orderliness and compulsivity,and on the other hand a pattern of strict rectitude, scrupulosity, dutifulness and morality. In both respects the obsessive-compulsive personality is conscientious; indeed, it has been labeled a disorder of extreme conscientiousness (Widiger et al., 2009). Antisocial personality disorder, in the present paper, is described as occupying the opposite end of the conscientiousness continuum. The antisocial is impulsive rather than compulsive, illicit rather than licit, and furtive rather than forthright.After clinically comparing the obsessive and antisocial personalities, the present paper invokes evolutionary theory to explain their resultant behavioral, ideological, political and demographic differences.

Starting from the cry of the seraphim in Isaiahʹ s prophecy, this article aims to follow the rhythm of the sacred harmony, transcending the symbols of the angelic world and of the divine names, to get to the face to face meeting between man and God, just as the seraphim, reflecting their existence, stand face to face. The finality of the sacred harmony is that, during the search for God inside the human being, He reveals Himself, which is the reason for the affirmation of “I Am that I Am.” Through its hypnotic cyclicality, the profane temporality has its own musicality. Its purpose is to incubate the unsuspected potencies of the beings “caught” in the material world. Due to the fact that it belongs to the aeonic time, the divine music will exceed in harmony the mechanical musicality of profane time, dilating and temporarily cancelling it. Isaiah is witness to such revelation offering access to the heavenly concert. He is witness to divine harmonies produced by two divine singers, whose musical history is presented in our article. The seraphim accompanied the chosen people after their exodus from Egypt. The cultic use of the trumpet is related to the characteristics and behaviour of the seraphim. The seraphic music does not belong to the Creator, but its lyrics speak about the presence of the Creator in two realities, a spiritual and a material one. Only the transcendence of the divine names that are sung/cried affirms a unique reality: God. The chant-cry is a divine invocation with a double aim. On the one hand, the angels and the people affirm God’s presence and call His name and, on the other, the Creator affirms His presence through the angels or in man, the one who is His image and His likeness. The divine music does not only create, it is also a means of communion, implementing the relation of man to God and, thus, God’s connection with man. It is a relation in which both filiation and paternity disappear inside the harmony of the mutual recognition produced by music, a reality much older than Adam’s language.

Ideas of nationalisms as masculine projects dominate literary texts by African male writers. The texts mirror the ways in which gender differentiation sanctions nationalist discourses and in turn how nationalist discourses reinforce gender hierarchies. This article draws on theoretical insights from the work of Anne McClintock and Elleke Boehmer to analyse two plays: Zintgraff and the Battle of Mankon by Bole Butake and Gilbert Doho and Hard Choice by Sunnie Ododo. The article argues that women are represented in these two plays as having an ambiguous relationship to nationalism. On the one hand, women are seen actively changing the face of politics in their societies, but on the other hand, the means by which they do so reduces them to stereotypes of their gender.

First Philosophy

The general objective of this study is to analyze the postulate of the ethics of otherness as the first philosophy, presented by Emmanuel Levinas. It is a proposal that runs through Levinas' thinking from his theoretical foundations, to his philosophical criticism. Levinas' thought presents itself as a new thought, as a critique of ontology and transcendental philosophy. For him, the concern with knowledge and with being made the other to be forgotten, placing the other in totality. Levinas proposes the ethics of otherness as sensitivity to the other. The subject says here I am, making myself responsible for the other in an infinite way, in a transcendence without return to myself, becoming hostage to the other, as an irrefutable responsibility. The idea of the infinite, present in the face of the other, points to a responsibility whoever more assumes himself, the more one is responsible, until the substitution by other.
