Jean Dubuffet (1901-1985)

“Dubuffet’s anti-relational imagery translates a freedom from hierarchical imperatives, a freedom won at the expense of composition, illusionism, perspective, color interaction, in a word, at the expense of “art” as his generation knew it. Psychologically, it was achieved by observing madness of the disintegration of categorical thought. Like the Art Brut artists he admires, Dubuffet freely constitutes celebrations, based on delusions, which he offers as an alternative to everyday life.”
