Twentieth-century avant-garde artists established chance operations as a critique of rational order
The use of chance in art emerged as a cultural response to industrialized violence and Newtonian determinism. Dada artists (Arp, Duchamp) used dropped objects and dice to reject rational structures; John Cage deployed the I Ching to remove composer preference from music; Tinguely built self-destroying machines to mirror the atomic age. This genealogy matters because contemporary generative coders inherit these moves: every call to random() in creative code participates in a lineage that is explicitly political, not merely aesthetic. Knowing the history helps practitioners articulate why they use randomness and avoid treating it as a neutral technical convenience.
Examples
Duchamp’s Three Standard Stoppages (1913): string dropped from 1 m height determined its own unit of measure — a critique of the metric system. Cage’s Music of Changes (1951): I Ching hexagrams determined pitch/duration.
Assessment
Name three pre-digital artists who used chance operations and describe the specific method each used to introduce randomness into their work.
