These two essays, written late in Jung's life, reflect his responses to the shattering experience of World War II and the dawn of mass society. Among his most influential works, "The Undiscovered Self" is a plea for his generation - and those to come - to continue the individual work of self-discovery and not abandon needed psychological reflection for the easy ephemera of mass culture. Only individual awareness of both the conscious and unconscious aspects of the human psyche, Jung tells us, will allow the great work of human culture to continue and thrive. Jung's reflections on self-knowledge and the exploration of the unconscious carry over into the second essay, "Symbols and the Interpretation of Dreams", completed shortly before his death in 1961. Describing dreams as communications from the unconscious, Jung explains how the symbols that occur in dreams compensate for repressed emotions and intuitions. This essay brings together Jung's fully evolved thoughts on the analysis of dreams and the healing of the rift between consciousness and the unconscious, ideas that are central to his system of psychology. This paperback edition of Jung's classic work includes a new foreword by Sonu Shamdasani, Philemon Professor of Jung History at University College London.

卡尔·古斯塔夫·荣格：1875年出生于瑞士北部的康斯坦斯湖畔，1961年逝世。他是瑞士著名的精神病医生，分析心理学的创始人，毕生致力于人类灵魂及其深处奥秘的探索，对研究人类的无意识心理做出了巨大贡献。

荣格曾受弗洛伊德的器重，担任国际精神分析学会第一任主席。他提出的集体无意识观点突破了弗洛伊德的无意识研究的思路与领域。因在里比多、无意识和人格发展的认识上产生重大分歧，特别是对里比多概念的不同见解，导致荣格从古典精神分析学派中分裂出来，创立了分析心理学。他把宗教与灵魂等弗洛伊德尚未注意到的重要问题引入分析心理学的领域中，以致其中一些概念带有浓厚的宗教神秘色彩，较晦涩难懂。荣格的人格理论包括三部分：意识、个人无意识与集体无意识。他认为，集体无意识与个体无意识不同，它潜存于每个人的内心深处，却从来不为人的意识所感知。从无意识这一概念出发，荣格把他的心理学理论广泛地应用到社会的各个领域，对人类的心灵探索、时代的精神潮流、文学艺术与宗教等方面都进行了深入细致的思考。
