Early work by the Soviet psychologist Lev Vygostky was connected with the special education of the so-called "defective" children. Vygotsky constructed blindness, deafness, and other functional disorders in children as "defects"  in the social system that alienates them from the so-called normal people. In the chapter, I am analysing Vygotsky's representation of the blind child as a subject of proletarian revolution, and his method of psychological and pedagogical "correction" as an allegory of cultural revolution in general.
