The 20th-century figure that influenced modernist literature through his groundbreaking work on the subconscious is <em>Carl Jung</em>. Modernist authors broke with previous ways of writing. They were highly influenced by the horrors of World War I and by the new ideas of the subconscious mind of both Carl Jung with his idea of the collective unconscious and Sigmund Freud's ideas of the fight between the conscious and the subconscious mind.
