This classic introduction to the psychology of Carl Gustav Jung is important because it is the only English original text he sanctioned in his lifetime. In his personal foreword, he wrote: 'Mrs Frieda Fordham has undertaken the by no means easy task of producing a readable resumé of all my various attempts at a better and more comprehensive understanding of the human psyche. She has delivered a fair and simple account of the main aspects of my psychological work. I am indebted to her for this admirable piece of work.'

Originally issued in 1953, this Introduction immediately became the standard first step for those eager to understand the varied work and thought of this remarkable man. Mrs Fordham explains her reason for attempting the work. She wrote: 'Most people have heard of the late C. G. Jung, often linking him vaguely with Sigmund Freud; and although the terms 'complex', 'introvert', and 'extravert' are often used in everyday speech, few realise they were coined by him. Jung’s influence has been far-reaching, touching many of the human sciences, and his ideas have proved of value in such widely differing fields as biology and theology. Many of his writings are technical, and even those of a general nature often appear somewhat obscure, but they contain a core of significance for everyone. This book aims at revealing this core to the reading public in language which is easily comprehensive and yet does not do violence to the subtlety and creative genius of one of the greatest modern psychologists.'
