The prisons of possibility are the many faces unfolding from a world that has been left to itself. They name the emergence of a problem running through the experience that anyone can gain today from reality: the experience that everything is possible yet we can do nothing. The experience that everything can be said yet there is nothing relevant to add. The experience that beyond the horizon there is only more of the same, a reiterated confirmation of what we have. How is it possible that in every option, alternative or choice the obviousness of this same world is reproduced?

At a moment when new emancipatory discurses are trying to recuperate the concept of possibility ("another world is possible") as a horizon for hope, it becomes urgent to explore deeply the place this concept occupies in our discurses, in the relationship we can maintain with reality, with the production of other realities. This is what the book En las prisiones de lo posible [In the Prisons of Possibility] proposes. Here we reproduce its central chapter, where we expound the principal paradoxes by which the law of possibility appears to confirm and form a solitary world.
