Stunned by the implications of Colagè's analysis of the cultural activation of the brain's Visual Word Form Area and the potential role of cultural neural reuse in the evolution of biology and culture, the authors build on his work in proposing a context for the first rudimentary hominin moral systems. They cross‐reference six domains: neuroscience on sleep, creativity, plasticity, and the Left Hemisphere Interpreter; palaeobiology; cognitive science; philosophy; traditional archaeology; and cognitive archaeology's theories on sleep changes in Homo erectus and consequences for later humans. The authors hypothesize that the human genome, when analyzed with findings from neuroscience and cognitive science, will confirm the evolutionary timing of an internal running monologue and other neural components that constitute moral decision making. The authors rely on practical modern philosophers to identify continuities with earlier primates, and one major discontinuity—some bright white moral line that may have been crossed more than once during the long and successful tenure of Homo erectus on Earth.
The evolution of thinking about traditional healing is examined to provide a conceptual foundation on which to understand the problems of integrating traditional healing within Western health delivery systems. Traditional healing is viewed as a distinctly different system that has a different model of disease and that operates within a different world view. Because of perceived clashes in values between the traditional and Western systems, differences in their manipulation of expectancy, and the degree to which the systems differ in healer charisma, an alternative to a model of integration is proposed. It is concluded that the Western and traditional systems are complementary and should be constructed to function alongside one another. A delivery system comparable to the Western approach to psychosomatic medicine is suggested.
Co‐creating knowledge takes a new approach to human phenotypic morality as a biologically based, human lineage specific (HLS) trait. Authors from very different backgrounds (anthropology and biology, on the one hand, and astronomy, philosophy, and theology, on the other) first review research on the nature and origins of morality using the social brain network, and studies of individuals who cannot “know good” or think morally because of brain dysfunction. They find these models helpful but insufficient, and turn to paleoanthropology, cognitive science, and neuroscience to understand human moral capacity and its origins long ago, in the genus Homo. An unusual narrative capturing “morality in action” takes the reader back 900,000 years, and then the authors analyze the essential features of moral thinking and behavior as expressed by early and later species on our lineage. In what has primarily been the province of philosophers to date, the authors’ morality model is presented for further scientific testing.
In this third and last article on the evolution of religious capacity, the authors focus on compassion, one of religious expression's common companions. They explore the various meanings of compassion, using Biblical and early related documents, and derive general cognitive components before an evolutionary analysis of compassion using their model. Then, in taking on neural reuse theory, they adapt a model from linguistics theory to understand how neural reuse could have operated to fix religious capacity in the human genome. They present a teaching tool on "Religious Capacity in Action," and develop an example of compassionate decision making in very early Homo sapiens in North Africa. They round out their analysis of compassion by exploring theory in neuroscience on a standard decision-making model, and investigate what goes on in the human brain when a values-based decision is made.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
