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 is an Dutch adaptation of an original German manuscript in collaboration with Caspari translated and adjusted by Constant. A summary of the Dutch text was published in 1974 in the exhibition catalogue at Gemeentemuseum Den Haag. Neither the original Dutch text of 125 pages nor the German manuscript of 165 pages was ever published as a whole until 2021.
