Ce dessin par Paul Otlet illustre avec un génie inventif les moyens de la connaissance. Il commente ainsi : « An instrumentation acting across distance which would combine at the same time radio, x-rays, cinema, and micro photography [and the since then invented television]. All the things of the universe and all those of man would be registered from afar as they were produced. Thus the moving image of the world would be established – its memory, its true duplicate. From afar anyone would be able to read the passage that, expanded or limited to the desired subject, could be projected on his individual screen. Thus, in his armchair anyone would be able to contemplate the whole of creation or particular parts of it ».
