Runaway social selection resulting from partner choice may have shaped aspects of human cooperation and complex sociality that are otherwise hard to account for. Social selection is the subtype of natural selection that results from the social behaviors of other individuals. Competition to be chosen as a social partner can, like competition to be chosen as a mate, result in runaway selection that shapes extreme traits. People prefer partners who display valuable resources and bestow them selectively on close partners. The (...) resulting phenotypic covariance between displays and preferences gives fitness advantages to both, creating runaway selection that could shape a whole suite of prosocial traits including altruism, moral capacities, empathy, and theory of mind. Even though they give a net fitness benefit, traits at the endpoint of runaway social selection can have substantial deleterious effects on other traits such as viability, ability to accumulate resources, or vulnerability to mental disorders. Social selection forces arising from self-interested partner choices may be an invisible hand that shaped capacities for commitment, altruism, and other prosocial capacities of the human social brain.

The dualistic structures permeating western culture emphasize radical discontinuity between humans and nonhumans, but receptive attention to nonhuman others discloses both continuity and difference prevailing between other forms of life and our own. Recognizing that agency and subjectivity abound within nature alerts us to our potential for dominating and oppressing nonhuman others, as individuals and as groups. Reciprocally, seeing ourselves as biological beings may facilitate reconstructing our social reality to undo such destructive relationships.

The values which are definitive of the humanist project, such as freedom and self-determination, are of central concern to environmentalism. This means, according to Lewis P. Hinchman, that environmentalists should seek a rapprochement with humanism, rather than rejecting it for its apparent anthropocentrism. He argues that this requires in turn the acceptance of those approaches to human self-understanding which are central to the hermeneutic traditions and the rejection of naturalist approaches, such as sociobiology, which is accused of producing deterministic, reifying, (...) reductionist, dehumanising forms of understanding of human beings and human life. This paper seeks to show that sociobiology does not pose the kinds of threat to humanism and environmentalism outlined by Hinchman. (shrink)

: Animal ethics has presented convincing arguments for the individual value of animals. Animals are not only valuable instrumentally or indirectly, but in themselves. Less has been written about interest conflicts between humans and other animals, and the use of animals in practice. The motive of this paper is to analyze different approaches to interest conflicts. It concentrates on six models, which are the rights model, the interest model, the mental complexity model, the special relations model, the multi-criteria model, and (...) the contextual model. Of these, the contextual model is the strongest, and carries clear consequences for the practical use of animals. (shrink)
