" Our estrangement from nature and the unconscious became entrenched roughly two thousand years ago, during the shift from the Age of the Great God Pan to that of Pisces that occurred with the suppression of the pagan mysteries and the rise of Christianity. The psychological shift that ensued left European civilization staring into two millennia of religious mania and persecution, warfare, materialism, and rationalism.
The monstrous forces of scientific industrialism and global politics that have been born into modern times were conceived at the time of the shattering of the symbiotic relationships with the plants that had bound us to nature from our dim beginnings. This left each human being frightened, guilt-burdened, and alone. Existential man was born. "
