Madness as the price of consciousness
Thomas Midwinter argues that schizophrenia is not a random defect but a by-product of the evolutionary leap that gave humans self-consciousness and language. On this view, early humans experienced one brain hemisphere's output as external voices, which they took for gods, and the auditory hallucinations of the modern schizophrenic are a residue of that older arrangement. Madness persists in every population because it is bound to the same mechanism that makes us human.
