What is it about?
Carey leaves unaddressed an important evolutionary puzzle: In the absence of a numeral list, how could a concept of natural number ever have arisen in the first place? Here we suggest that the initial development of natural number must have bootstrapped on a material culture scaffold of some sort, and illustrate how this might have occurred using strings of beads.

Perspectives
I am interested in how societies become numerate by using and recruiting material forms into the cognitive system for numbers over generations of collaborative effort. The manuovisually engaged domain of material forms is a primary mechanism for realizing and elaborating numerical concepts. I also look at the effect this elaborational mechanism has on conceptual content, and what this might augur about the future of human cognition.
