Abstract

The book integrates humans’ biological lives as animals with acculturation and interaction within diverse social worlds. Recent work in evolutionary biology, the social theory of practices, and cognition as embodied and enactive shows how aspects of human life often treated as social or cognitive are integrated “naturecultural” phenomena. Human evolution enables people’s varied biological development in practice-differentiated environments sustained by ongoing niche reconstruction. These naturecultural aspects of human life include language and other expressive repertoires; cultivated bodily skills; differentiated practical and cultural domains and their associated settings and equipmental complexes; critical assessment of lives and practices; and power and resistance. This interdependent, practice-differentiated way of life explains how humans are accountable and responsive to diverse normative concerns. Our moral, social, practical, skillful, epistemic, conceptual, aesthetic, and other normative concerns are evolved, “two-dimensional” transformations of other animals’ one-dimensional biological success or failure in sustaining their lineages. These diverse normative concerns are not already-determinate norms, however. They indicate what is at issue and at stake in the ongoing development of various practices and their mutual interdependence, including how people express and reason about those issues discursively. Social power is thereby also a normative phenomenon, expressing how causal capacities and actions reconfigure the normative significance of other people’s situations. The book primarily addresses the biological significance of people’s situated involvement with one another. It nevertheless also highlights the social-ecological interdependence of people’s practice-differentiated ways of life with many non-human companion species, from microbial symbionts and pathogens to domesticated or commensal plants and animals.
