With findings from cognitive science, neuroscience, information science, and paleoanthropology, an anthropologist and astronomer-priest team take a new look at the nature of morality, and suggest parameters that are often very different from the philosophical and theological literatures. They see morality as a biologically-based arbitration mechanism that works along a timeline with a valence of good to bad. It is rational, purposeful, social, and affected by emotion but not dominated by it. The authors examine the age and sex structure, family (...) roles, environment, cognition, and lifeway of Homo erectus, an early hominin who arose 1.9 million years ago, and propose that he had a rudimentary moral system that his biology and culture enabled – but only after he learned to control fire. Hearths gave rise to an intense, social, emotional, experiential context where belief systems could be learned by youth before they achieved adult cognition. (shrink)

In my paper, I set The Language Animal against a broader picture of Taylor’s intellectual trajectory. Sources of the Self (1989) left three major questions open in its wake: (a) the viability of religious moral sources in a ‘secular’ age; (b) the compatibility between a robust moral realism and a genealogical account of modern identity; (c) the meaning and destiny of the so-called ‘linguistic turn’. This is the framing topic of his last book. Although Taylor’s variety of hermeneutics is unquestionably (...) a product of the linguistic turn, he has operated with a broad notion of the linguistic capacity from the start. Language is, for him, a shared activity and the acknowledgment of its animal embeddedness functions in his work as an antidote against any too idealized a view of the kind of creatures that humans are. In his earlier writings, however, a structural tension lurked below the surface between a Gadamerian notion of Sprache and a more phenomenological, Merleau-Pontyan, embodied outlook that was less modeled on articulate speech. My claim is that his new book marks a shift from a more speech-oriented to a more body-oriented understanding of language. (shrink)

The paper aims at proposing an extended notion of epigenesis acknowledging an actual causal import to the phenotypic dimension for the evolutionary diversification of life forms. “Introductory remarks” section offers introductory remarks on the issue of epigenesis contrasting it with ancient and modern preformationist views. In “Transmutation of forms: phenotypic variation, diversification, and complexification” section we propose to intend epigenesis as a process of phenotypic formation and diversification dependent on environmental influences, independent of changes in the genomic nucleotide sequence, and (...) occurring during the whole life span. Then, “Evolvability and phenotypic evolution” section focuses on phenotypic plasticity and offers an overview of basic properties that allows biological systems to be evolvable—i.e. to have the potentiality of producing phenotypic variation. Successively, the emphasis is put on environmentally-induced modifications in the regulation of gene expression giving rise to phenotypic variation and diversification. After some brief considerations on the debated issue of epigenetic inheritance, the issue of culture is considered. The key point is that, in the case of humans and of the evolutionary history of the genus Homo at least, the environment is also, importantly, the cultural environment. Thus, “Bio-cultural feedback” section argues that a bio-cultural feedback should be acknowledged in the “epigenic” processes leading to phenotypic diversification and innovation in Homo evolution. Finally, “Brain plasticity and cultural neural reuse” section introduces the notion of “cultural neural reuse”, which refers to phenotypic/neural modifications induced by specific features of the cultural environment that are effective in human cultural evolution without involving genetic changes. Therefore, cultural neural reuse may be regarded as a key instance of the bio-cultural feedback and ultimately of the extended notion of epigenesis proposed in this work. (shrink)

Intrigued by the possible paths that the evolution of religious capacity may have taken, the authors identify a series of six major building blocks that form a foundation for religious capacity in genus Homo. Homo neanderthalensis and Homo sapiens idaltu are examined for early signs of religious capacity. Then, after an exploration of human plasticity and why it is so important, the analysis leads to a final building block that characterizes only Homo sapiens sapiens, beginning 200,000–400,000 years ago, when all (...) the other cognitive and neurological underpinnings gradually came together. Because the timing of cognitive evolution has become an issue, the authors identify the time periods for these building blocks based on findings from modern cognitive science, neuroscience, genomic science, the new cognitive archaeology, and traditional stones-and-bones archaeology. The result is a logical, and even a likely story 55–65 million years long, which leads to the evolution of religious capacity in modern human beings. (shrink)

On the basis of recent advancements in both neuroscience and archaeology, we propose a plausible biocultural mechanism at the basis of cultural evolution. The proposed mechanism, which relies on the notions of cultural exaptation and cultural neural reuse, may account for the asynchronous, discontinuous, and patchy emergence of innovations around the globe. Cultural exaptation refers to the reuse of previously devised cultural features for new purposes. Cultural neural reuse refers to cases in which exposure to cultural practices induces the formation, (...) activation, and stabilization of new functional and/or structural brain networks during the individual lifespan. The invention of writing is interpreted as a case of cultural exaptation of previous devices to record information, in use since at least the Early Later Stone Age and the beginning of the Upper Paleolithic. The measurable changes in brain structure and functioning caused by learning to read are proposed as an exemplar case of cultural neural reuse. It is argued that repeated cycles of cultural exaptation, development of appropriate strategies of cultural transmission, and ensuing cultural neural reuse represent the fundamental mechanism that has regulated the cultural evolution of our lineage. A general predictive model of when and under which circumstances the proposed mechanism should be expected to occur is proposed, and the relationship of our mechanism with gene-culture coevolutionary models is discussed.

Co-creating knowledge takes a new approach to human phenotypic morality as a biologically based, human lineage specific trait. Authors from very different backgrounds 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. (shrink)

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.

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.
