Paul Schuitema. Rationalisatie en de 6 urige arbeidsdag / Arthur Müller Lehning. Amsterdam: Nederlandsch Syndicalistisch Vakverbond, 1931
“For Schuitema, the innovation of form was not a goal in itself, but derived from a desire to play a real role in the production process as an artist. In his texts, he repeatedly emphasised the importance of the then existing technical means of production. Schuitema believed their acceptance was an important condition for the actualisation of a new prospective culture. Yet he was nevertheless convinced from the start that technology in itself was incapable of solving societal problems. He therefore applied his design capacities not only in advertising, but also in support of the political cause.”
