Boredom
Perhaps it is true … that the openness of the human world (insofar as it is also and primarily an openness to the essential conflict between disconcealment and concealment) can be achieved only by means of an operation enacted upon the not-open of the animal world. And the place of this operation – in which human openness in a world and animal openness toward its disinhibitor seem for a moment to meet – is boredom.
