Jung died in 1961 without ever having presented a systematic summary of his psychology. For the past 30-plus years, his ideas have been explored, explained and amplified by thousands of others with varying results. This book takes the reader to the source. It was designed for those seeking an understanding of relevant terms and concepts as they were used by Jung himself. There are choice extracts from his Collected Works but no reference to other writers. It is not a critique or a defence of Jung’s though but a guide to its richness and an illustration of the broad scope and inter-relationship of his interests. Overall, the Lexicon contains a comprehensive overview of the basic principles of analytical psychology.
