Circular Insanity is a book containing fragmentary texts by the French writer and Dadaist Henri Michaux. His writings arose from him seeing himself as a “case of circular insanity.” Tormented by his constant inner restlessness, he describes cities that are breaking apart and tells of giants mutilating themselves. He feels “simultaneously lethargic, limp, and under pressure, nervous.” Sometimes he sees himself as a “skier at the bottom of a well,” sometimes as a “word trying to move forward with the speed of thought.” At first, the reader is only slightly disoriented; the type area begins to dance and the lines initially take on barely perceptible wave forms. Later, the entire construction of the text disintegrates, with total confusion created by printed transparent sheets that superimpose texts and are moved by the reader.
