Maybe “You don’t want to be a robot ghost/occupied inside a human host” isn’t their finest hour, lyrically speaking, but it’s made up for later, both in ‘God Is Dead?’ (which not only rhymes tomb, gloom and doom, but contains “The blood runs free, the rain turns red/give me the wine, you keep the bread”) and also ‘Loner’. ‘Loner’ is pure bedroom existentialism for alienated metalheads, which is Black Sabbath’s stock in trade: “Communication’s an impossibility/his own best friend but he’s his own worst enemy.” [Source]
