The subject of this dissertation is the Finland-Swedish author Gunnar Björling (1887-1960) and his journey towards Modernism. The principle thesis of this dissertation, the idea that Björling's distinctive language cannot be understood without an underlying modernistic current, is outlined in Chapter I. It also discusses the idea that Modernism cannot be reduced to a matter of style, but encompasses particular values, ideological stances and practical matters, such as the forming of alliances, writing manifestos and publishing journals.
