Stein, Murray. _Jung’s Map of the Soul: An Introduction_, 1998. Jung's professional career spans from 1900, when he began his psychiatric studies at the Burghölzli Klink, to 1961, when he passed away at Küsnacht on Lake Zurich. Most of his theories had been mapped out by 1930, the halfway point. Jung used the word "amplification" to describe his process of using comparative mythology and world culture to bring aspects of the psyche into focus. Jung's chief teacher in his early years was Eugen Bleuler, who coined the term "schizophrenia". Jung's map of the soul is the first map of an uncharted territory. There are bound to be mistakes. But as a work of art, it is beautiful and will not date. Jung was an artist and visionary who put his map to scientific test. The scientific process leaves his work rough and not entirely consistent, because he wasn't able to smooth things over the way an artist would, but had to work with whatever came up empirically. Jung claimed that he was trying to describe a central fire by putting mirrors around it. There were bound to be places where the edges of the mirror don't align.
