Les arts peuvent-ils et doivent-ils « unir leurs forces » ?

Symbolism acted as a pioneer in the artistic movements of the 20th century. The Belle Epoque was followed by the fracture brought about by World War I and by attempts to rebuild the world (with scientific research, various artistic experiments, practice of dialogue between the arts). In addition to contemporary testimonies and commemorations, some artists decided to wipe up the past (Dadaists) and to suggest a new reality (Surrealists). This article reports their activity in Paris (poetry, music, dance) and the revolution of Russian Ballet in order to document the revival and renewal in thought and creativity. The innovative, even provocative dialogue between the arts during the War and even more the immediate post-war period greatly contributed to another remembrance and to the credibility of an alternative future.
