De dialektiek van het experiment
1965
In De dialektiek van het experiment (The Dialectic of the Experiment) Constant looks back at the preceding period in his career and the radical transformation that took place in his artistic development during the 1950s. He declares that while he can visualize ‘unitary urbanism’, the present state of society is fundamentally different from the societal situation essential to the realization of such a revolutionary programme. Consequently, unitary urbanism remains limited to isolated experiments and a programme.
New Babylon: een schets voor een cultuur

A summary of the Dutch text was published in 1974 in the exhibition catalogue at Gemeentemuseum Den Haag.
