...in Achilles' dream at the beginning of Book 23 of the Iliad, the psyche of the dead Patroclus visits him, and when he tries to hug it in his arms, it sinks gibbering into the earth. The grizzly scenes in Hades in Books 11 and 24 of the Odyssey use psyche in a similar way. The term in these instances has an almost opposite sense from its meaning in the rest of both Iliad and Odyssey. Not life, but that which exists after life has ceased. Not what is bled out of one's veins in battle, but the soul or ghost that goes to Hades, a concept that is otherwise unheard of in Greek literature until Pindar, around 500 B.C. In all the intervening writers we have been looking at through the eighth and seventh centuries B.C., psyche is never the ghost-soul, but always has its original meaning of life or livingness. Now, no amount of twisting about in semantic origins can reconcile these two gratingly different significations for psyche, one relating to life and the other to death. The obvious suggestion here is that these alien incongruities in Homer are interpolations of a period much later than the ostensible period of the poems. And indeed this is what the majority of scholars are sure of on much more ample grounds than we can go into here. Since this meaning of psyche does not appear until Pindar, we may be fairly confident that these passages about Hades and the souls of the dead abiding there in its shades were added into the Homeric poems shortly before Pindar, sometime in the sixth century B.C. The problem then is how and why did this dramatically different concept of psyche come about? And let us be clear here that the only thing we are talking about is the application of the old word for life to what survives after death and its separability from the body. The actual survival, as we have seen in previous chapters, is not in doubt. According to the theory of the bicameral mind, hallucinations of a person in some authority could continue after death as an everyday matter.
