Human propensities that are the products of Darwinian evolution may combine to generate a form of social behavior that is not itself a direct result of such pressure. This possibility may provide a satisfying explanation for the origin of socially transmitted rules such as the incest taboo. Similarly, the regulatory processes of development that generated adaptations to the environment in the circumstances in which they evolved can produce surprising and sometimes maladaptive consequences for the individual in modern conditions. These combinatorial (...) aspects of social and developmental dynamics leave a subtle but not wholly uninteresting role for evolutionary biology in explaining the origins of human morality. (shrink)

This article develops a theory for how caringbehavior fits into the makeup of humans andother mammals. Biochemical evidence for threemajor patterns of response to stressful orotherwise complex situations is reviewed. There is the classic fight-or-flight response;the dissociative response, involving emotionalwithdrawal and disengagement; and the bondingresponse, a variant of which Taylor et al. (2000) called tend-and-befriend. All three ofthese responses can be explained as adaptationsthat have been selected for in evolution andare shared between humans and other mammals. Yet each of us (...) contains varying tendenciestoward all of these responses. How doesdevelopment interact with genes to influencethese tendencies? How do individuals,societies, and institutions make choicesbetween these types of responses?We review the evidence, based on behavioral,lesion, single-cell, and brain imaging studies,for cortical-subcortical interactions involvedin all three of these response types, andpropose partial neural network models for someof these interactions. We propose that theorbitomedial prefrontal cortex mediates thischoice process. This area of prefrontal cortexperforms this mediation through its connectionswith areas of sensory and association cortexthat represent social contexts or stimuli, andwith areas of the hypothalamus, limbic system,and autonomic nervous system that representemotional states or classes of response patterns.The article concludes with implications of ourtheory for social interactions andinstitutions. We argue that despite the wideprevalence of fight-or-flight responses, thebonding, caring responses remain available. Weshow with historical and contemporary exampleshow social settings – whether in education,work places, families, politics, and informalsocial customs – can be designed to supportand enhance the natural caring responses of thebrain.

The article develops and justifies, on the basis of the epistemological argumentation theory, two central pieces of the theory of evaluative argumentation interpretation: 1. criteria for recognizing argument types and 2. rules for adding reasons to create ideal arguments. Ad 1: The criteria for identifying argument types are a selection of essential elements from the definitions of the respective argument types. Ad 2: After presenting the general principles for adding reasons (benevolence, authenticity, immanence, optimization), heuristics are proposed for finding missing (...) reasons, for deductive arguments, e.g., semantic tableaux are suggested.
