This book is the culmination of a project that unfolded over the course of several years during which we sought ways to explore art, its development, and its role in the construction of knowledge. Two questions emerged from early discussions with our Jean Piaget Society colleagues, and with each other—questions that focused our efforts and galvanized our project. The first asked, “What are the origins of art, in an individual child, in a specific culture, and in the species as a whole?” And the second, “What is the epistemological status of creative, aesthetic activity in generating new knowledge?”
