‘Through a carefully selected set of essays, the editors have created a marvelous Symposium, conducted by the late Gerald Duveen, where he, Piaget, Moscovici, Vygotsky and Bartlett explore the need for a synthetic approach to the nature of human development. A challenging and rewarding reading experience that taught me a lot’ - Professor Michael Cole, Director of Laboratory for Comparative Human Cognition, University of California San Diego ‘Gerard Duveen was a remarkable scholar who developed an original conceptual approach linking together developmental, cultural and social psychology. In this volume the editors present Duveen's critical engagement with Piaget's and Moscovici's theories and his original thought in advancing difficult concepts like decentration, social representations, identities, beliefs and doubts, among many others. The volume, building on intellectual scholarship of the highest standard, will be inspirational for researchers in human and social sciences’ - Ivana Markova, Emeritus Professor in Psychology, University of Stirling
