" The effective, present, ultimate and primary being, the thing itself, are in principle apprehended in transparency through their perspectives, offer themselves therefore only to someone who wishes not to have them but to see them, not to hold them as with forceps, or to immobilize them as under the
objective of a microscope, but to let them be and to witness their continued being—to someone who therefore limits himself to giving them the hollow, the free space they ask for in return, the resonance they require, who follows their own movement, who is therefore not a nothingness the full being would come to stop up, but a question consonant with the porous being which it questions and from which it obtains not an answer, but a confirmation of its astonishment. It is necessary to comprehend perception as this interrogative thought which lets the perceived world be rather than posits it, before which the things form and undo themselves in a sort of gliding, beneath the yes and the no. "
― Maurice Merleau-Ponty , The Visible and the Invisible
