Ludwig's book is outstanding. It pulls together a mound of pertinent data, much of it new, into coherent patterns...Throughout the book the reader is offered a wealth of insights and serious questions...Ludwig's development of a Creative Achievement Scale [is] a valued contribution in its own right, allowing researchers a comprehensive objective tool for scoring subjects' degree of achievement... Ludwig has cleared up much of the confusion and opinionated muddleheadedness... that has been attached to the topic and the thinking regarding a relationship between psychopathology and creativity.
