If you can guess that what Zen and Psychoanalysis have in common is their aspiration towards fuller awareness, you might as well pick a more thorough book. However, if all you need is a straightforward introduction to philosophy, or more specifically, a simple sketch of Western and Eastern forms of humanism, this paper can aid you in this task. With slow, undemanding progression that underlines the crucial aspects repeatedly, it tells us the familiar story about why all modes of being, without proper guidance of trained healers, are left in a state of lower consciousness or if one is particularly unlucky, in madness.
Though I think the focus on the differences rather than the similarities between these distant forms of thought would make the book much more substantial, the author doesn’t want to enlarge the gap between them even further and contrasts them only with the aim of moving them closer. In the more rewarding end, the asymmetry finally outshines his aim – what psychoanalysis or Western thought lacks is awareness that in order to become a united, fulfilled person doesn’t simply mean to dig for one’s faults and traumas and make them productive, but a deeper, positive change of personality, where these faults don’t need a special treatment, but a general one with the rest of one’s traits. Fromm’s vision of psychoanalysis being the basis for further Zen trainings seems a bit far-fetched in this regard, since Zen’s interpretations of human’s shortcomings are entirely different.
