"Dick paints Eldritch as a nefarious and possibly alien figure, his "three stigmata" (a prosthetic arm, eyes, and teeth) symbolizing what Dick saw as the "negative trinity of alienation, blurred reality, and despair" we all risk by losing our capacity for empathy and by giving into the technology of control." --Erik Davis; http://www.techgnosis.com/index_pkdnet.html
