This book discusses synchronicity, quantum physics, Hume, Whitehead, Habermas, Jung, causality, semantics, and many other rather rigorous and/or mind-bending subjects, yet the publisher has chosen to market it as a sort of relationship/new-age/self-help book. Accordingly, the many paragraph-length blurbs on the inside flap and back cover greatly misrepresent, soften, and gloss over the book's real subject - which is, in short, inter-subjectivity: that is, the way in which relations between individuals are truly mutual, co-creating bonds and not mere "interpretations" and "versions" spun-out by one self-conscious mind grappling with the irreconcilable difficulty of another self-conscious mind getting all up in its face. The Other is not necessarily at odds with me, according to this view; human relations are not hopelessly mediated and manipulated by MERE language games and rival interpretations. While that may sound dry and abstract, it is asserting that, quite simply, we are not just fuck-heads walking around in a solipsistic cause-and-effect mechanism playing itself out for no good reason. This is not the first or the only book to present this information, but it is done with extreme clarity, care, and scope (DeQuincey is a teacher, and it is obvious he has had to present these ideas to a variety of audiences with varying attention spans, and much of it has apparently passed that trial by fire). This is a sophisticated and comprehensive book that has been poorly marketed to a niche readership that would be turned-off by anything "intellectual."
