Throughout his works Jung repeatedly says he is a scientist, his findings are empirically based, & therapy must center on the individual client rather than upon theory. This volume (in addition to CW1) supports these contentions by describing the many experiments Jung conducted. Contemporary "post-Jungians," might take this volume as a failed attempt, but I do not. Jung's view was more a balance of nature (biology, genetics, etc.) AND nurture (environment, learning, etc.). Jung helped evolve psychology towards becoming a science--vs. the psychology of ignorance he inherited. This is a VERY important work (though perhaps a bit boring to many readers) which modern readers are advised to peruse to understand the context within which Jung worked, explored, & experimented. Per modern Knowledge Management, knowledge (vs. data or information) requires context to be actionable. In addition, this work has some interesting quotes such as: p. 245 "All our thinking and acting, the vast bulk of which appears to us to be conscious, actually consist of all those bits that are finely determined by innumerable impulses completely outside consciousness. To our ego-consciousness the association process seems to be its own work, subject to its judgment, free will, and concentration; in reality, however, as our experiment beautifully shows, ego-consciousness is merely the marionette that dances on the stage, moved by a concealed mechanism. (note 39) From this we can also gather that those who equate psyche with consciousness actually take part en pro toto;" p. 444 "no psychic occurrence is a thing in and by itself but rather the resultant of the entire psychological past;" & p. 444 "Words are really a kind of shorthand version of actions, situations, and things...the linguistic surrogate for reality; at the same time we must not forget what the stimulus-word will almost without exception conjure up its corresponding situation."
