This process of assimilation, which takes place in depth, requires a state of relaxation that is becoming rarer and rarer. If sleep is the apogee of physical relaxation, boredom is the apogee of mental relaxation. Boredom is the dream bird that hatches the egg of experience. A rustling in the leaves drives him away. His nesting places - the activities that are intimately associated with boredom - are already extinct in the cities and are declining in the country as well. With this the gift for listening is lost and the community of listeners disappears. For storytelling is always the art of repeated stories, and this art is lost when the stories are no longer retained.

Ursprung des deutschen Trauerspiels (Origin of German Tragic Drama 1928). A completed manuscript which Benjamin had carried in his suitcase disappeared after his death and has not been recovered. In 1917 he transferred to the University of Bern; there he met Ernst Bloch and Dora Sophie Pollak (née Kellner) (1890–1964) whom he later married.

His turn to Marxism in the 1930s was partly due to the influence of Bertolt Brecht whose critical aesthetics developed epic theatre and its Verfremdungseffekt (defamiliarisation alienation). Benjamin committed suicide in Portbou at the French–Spanish border while attempting to escape from the Nazis. Combining elements of German idealism or Romanticism Historical Materialism and Jewish mysticism Benjamin made enduring and influential contributions to aesthetic theory and Western Marxism and is associated with the Frankfurt School.
