Paolo Naldini, director of Cittadellarte, proposes an editorial on the Venice Bienniale: “Having imagination in power”, he says, “is not enough, just as the power of imagination is not enough: we also need a good dose of practices, methods, prototypes and their actual results. The instances and ideas that inhabit the worlds that this Biennale invites us to (re)discover, not only seem to me to be fully valid, but I believe it would be appropriate for them to form the basis of any contemporary cultural operation committed to tackling the epochal challenges we are facing. So, fine. But in the Bienniales I would like to see, and which we need, there should be, in my opinion, much more. So what is missing in this milk of dreams? The rennet, the enzyme that makes dreams precipitate and gives them substance”.
