"The dark dangerous forest is still there, my friends. Beyond the space of the astronauts and the astronomers, beyond the dark, tangled regions of Freudian and Jungian psychiatry, beyond the dubious psi-realms of Dr. Rhine, beyond the areas policed by the commissars and priests and motivations-research men, far, far beyond the mad, beat, half-hysterical laughter... the utterly unknown still is and the eerie and ghostly lurk, as much wrapped in mystery as ever." —Fritz Leiber (via 1five1two)
