Abstract

What is the core of the distinctiveness of Homo sapiens? Some of the most famous hypotheses include tool use and tool making, language, free will and moral agency, self-consciousness, mind itself, and reason or rational problem-solving. All these answers are partly true. But recent work in comparative psychology, primatology, and cognitive science have converged on a conception of human distinctiveness that underlies these. Remarkably, it was explored a century ago by George Herbert Mead. The American pragmatists played a special role in the development of non-reductive naturalism. But among them, Mead uniquely endorsed the notion of “emergence” developed by the British Emergentists. This led him to an analysis of the emergence of the human self and mind out of social processes, most famously employing his concept of “significant gesture.” In recent decades both notions have been buttressed by philosophical and scientific work. Emergence has returned in the sciences of nonlinear dynamics and complexity, and has been re-conceptualized by philosophers like Wiliiam Wimsatt. Mead’s social conception of the human mind and self have been repurposed by a host of scientists, as in Michael Tomasello’s conception of “joint intentionality” and Antonio Damasio’s analysis of self-consciousness. These developments show that Mead was remarkably prescient in his core insights.
