What begins as a philosophical exchange between the noted philosopher and broadcaster Bryan Magee and the late Martin Milligan, activist and philosopher blind almost from birth, develops into a personal and intense discussion of the implications of blindness. The debate is vigorous and often heated; sometimes contentious, it is always stimulating. In discussing the range of blind experience, from those born blind to those who become blind—including those who have to cope with the shock of gaining sight they had never before possessed—On Blindness argues strongly against the notion that blindness is a simple experience. In doing so, this extraordinary book casts new light on one of the most fundamental aspects of human experience.
