"'Question' was open because it had not yet received any form; it was a kind of prime matter, or a substance that existed in a realm of potentiality, an indefinite state that had not yet become anything in particular and maybe never would. But any formed object, on the other hand, would have denied all that: if it has already received form it is over, closed, ended; it has slid from the vague cloud of potentiality into a collision with the flat wall of fact that lay hidden behind it.
