Samenvatting

Sometimes dreams become reality, but there are also many examples in which manic ideas for image-defining projects turn into fiascos. How do you find the right balance in the planning and decision-making of image-defining projects between taming manic mechanisms that cause these projects to fail and unleashing manic mechanisms that are necessary to make these projects happen? This article attempts to answer this question by exploring how the taming of mania (through welfare-economic analysis) and the unleashing of vision and ambition (through imagination) can be combined in a better way. We call this a search for an ‘imaginative utilitarianism’ and draw up three preconditions under which this approach can work: (1) more attention to incremental and less grotesque projects, (2) a different appreciation and historiography that places individuals less centrally and also appreciates what has not been built, and (3) a stronger interweaving between the design process and a welfare-economic approach.
