Psychological Types is one of Jungs most important & most famous works. First published by Routledge (Kegan Paul) in the early 1920s it appeared after Jungs so-called fallow period during which he published little & it is perhaps the first significant book to appear after his own confrontation with the unconscious. It is the book that introduced the world to the terms extravert & introvert. Though very much associated with the unconscious in Psychological Types Jung shows himself to be a supreme theorist of the conscious. In putting forward his system of psychological types Jung provides a means for understanding ourselves & the world around us: our different patterns of behaviour our relationships marriage national & international conflict organizational functioning. Appearing in paperback for the first time this central volume from Jungs Collected Works will be essential to anyone requiring a proper understanding of Jungs psychology.
