Philippe Soupault
Back in Paris, Breton joined in Dada activities and started the literary journal "Littérature" along with Louis Aragon and Philippe Soupault. They began experimenting with automatic writing—spontaneously writing without censoring their thoughts—and published the writings, as well as accounts of dreams, in the magazine. Breton and Soupault continued writing evolving their techniques of automatism and published "The Magnetic Fields" (1920).
