For decades, Cognitive Science has been grappling with the issue of how to best understand the interactions between symbolic and subsymbolic cognition. In this ambitious and wide-ranging book, [Ron] Sun boldly takes it as a starting point that our minds are dual and implements his hypothesis as a hybrid computational model that he then compares the behavior of with that of human subjects exposed to implicit learning tasks. The result is a sometimes exhilarating romp through many issues central to contemporary cognitive science, including consciousness, the role of culture and embodiment in cognition, and the interactions between bottom-up and top-down processing. Whether or not one agrees with Sun's perspective, this book will challenge anyone with an interest in understanding how the mind works. --- Axel Cleermans, Universitè Libre de Bruxelles
