Tristan Tzara’s lecture, delivered in March 1946 in Prague, is introduced with an apology for “the Munich betrayal” and French political participation in it. Tzara then presents a thorough reflection on the birth and development of the Dada movement. Emphasising the feelings of frustration of the 1914-1918 war generation, he shows how “Dada was born out of moral necessity, out of the unshakeable determination to achieve moral absoluteness.” As one of Dada’s lasting contributions he singles out choosing “spontaneity” as “our one life rule”. Without disregarding the movement’s scandalous aspects, Tzara carefully and eruditely points out its continuity with the revolutionary spirit of French poetry, esp. Rimbaud, Verlaine, Jarry and Apollinaire.This excerpt ends on Tzara’s noting how “out of the ashes of Dada that saw its role as finished” surrealism was born.
