This book was originally published in 1981 and the theme of universals attracted a great deal of attention in the decade preceding publication. Psychologists and linguists in particular attempted to identify substantive universals that underlie the social diversity across cultures, which anthropologists and others documented. The contributors to this volume all focus on the relevant data in Africa to explain and test the major questions at issue. The book is divided into three main sections, dealing respectively with perception, cognitive development and language. There is also a general Review and Prospectus by Jerome Bruner, and a wide-ranging introduction to the philosophical background by Ernst Gellner. The volume will be of particular interest to cross-cultural psychologists, linguists, Africanists and anthropologists.
