Synchronicity: An Acausal Connecting Principle: From The Collected Works of C.G. Jung, Volume 8, Bollingen Series XX (1960), translated by: R.F.C. Hull (1973), 2010 edition

This book, originally a scientific paper written by one of my favorite scientists of all time (one of the rare scientists willing to admit to the crippling limitations of the so-called scientific method), was a bit over my head. Jung assumes he is writing for other well educated scientists, and makes no qualms about quoting Greek, Latin, or some other original source to make a point. Thus many points are lost to me, but I was able to understand enough to at least bolster my own grasp of what Jung himself considered his most significant contribution to the art of science: synchronicity.

Jung is the only scientists I know of who seems to understand the material reality of the immaterial phenomenon I like to call the Living truth, which he calls the psychoid, and is the basis of numerous theological and metaphysical concepts, such as Christ and Buddha, to mention just two.
