HELP! What does this quote mean: "But why should we suppose this model of free and fluid 'exchange' between...?

photography and language to be true or desirable? How do we account for the stubbornness of the naïve, superstitious view of photography? What could possibly motivate the persistence in erroneous beliefs about the radical difference between images and words and the special status of photography? Are these mistaken beliefs simply conceptual errors, like mistakes in arithmetic? Or are they more on the order of ideological beliefs, convictions that resist change by ordinary means of persuasion and demonstration? What if it were the case that the “relics” which “obstruct” our view of photography also constitute that view? What if the only adequate formulation of the relation of photography and language was a paradox: photography both is not a language?"
