A New Paradigm: Beyond Graphic User Interface...Now?

And it is true in every field, in science as in politics, in morals, in art. Every idea is thought, every picture painted, out of certain assumptions or conventions which are so basic, so firmly fixed for the one who thought the idea or who painted the picture that he neither pays heed to them, nor, for that matter, introduces them into his picture or his idea; nor do we find them there in any guise except as presupposed and left, as it were, at one side. This is why we sometimes fail to understand an idea or a picture; we lack the clue to the enigma, the key to the secret convention. —- José Ortega y Gasset, What is Philosophy
