Excerpt: As we know well enough from our own experience, at that level of elaboration, the “permanence” or “universality” of our cognitive constructs tends to become precarious. But even if it did not, even if we could achieve perfect intersubjective agreement of structures, it still would not get us across the border of the black box, because all it would tell us with certainty is that we, collectively, have found one viable construction. Such a construction becomes no more “real,” in the ontological sense, if we share it – it would still be based solely on signals on our side of the construct we have called “experiential interface,” and on the particular way in which we have categorized, processed, and coordinated these signals as input to, or output from, the construct we have called “universe.”
