Can we say that a kind of grammatical chasm exists between the form of the proposition and that of the question? Is there a kind of world, as it were, of the question, whose difference, verging on the suspicion of a kind of lack, sets it in perpetual opposition to that other world, that of the statement? [...] And when it comes to actions, are there those that one could designate as interrogative? And what about objects?
