My ideas developed under the influence of the bohemians or rather under Hans Jager [leader of the 'Kristiania Bohemia' since 1883]. Many people have mistakenly claimed that my ideas were formed under the influence of Strindberg and the Germans.... but that is wrong. They had already been formed by then.
