The prophet engages in futuring fantasy. The prophet does not ask if the vision can be implemented, for questions of implementation are of no consequence until the vision can be imagined. The imagination must come before the implementation. Our culture is competent to implement almost anything and to imagine almost nothing. The same royal consciousness that make it possible to implement anything and everything is the one that shrinks imagination because imagination is a danger. Thus every totalitarian regime is frightened of the artist. It is the vocation of the prophet to keep alive the ministry of imagination, to keep on conjuring and proposing futures alternative to the single one the king wants to urge as the only thinkable one.
