The purpose of this thesis is to present, contextualize and interpret the educational philosophy of Natanael Beskow between 1920–1932. The examined source material consists of articles published in the journal Studiekamraten which ordinated from Birkagården folk high school (Birkagårdens folkhögskola) where Beskow served as principal. The content of the articles is related to previous research and to a historical context. This historical context deals primarily with the modernization of the Swedish society. The basic theoretical perspectives are theories about Bildung and liberal adult education presented by Bernt Gustavsson. This thesis finds that Beskow regarded education as an inner process that gradually raised and developed the individual’s moral capacity. Such neo-humanist views dominated pedagogical philosophy of the time. In addition, Beskow saw education as an instrument that could initiate a spiritual awakening. A challenging alternative to the established liberal adult education movement (folkbildningsrörelsen) was the class struggle education (klasskampsbildningen) that was formed within SKP. Its advocates regularly attacked Birkagården folk high school. Beskow was critical of the movement. He represented a contrasting ideal built around mutuality and democracy which partly originated from the foreign settlement movement.
