Humanity lends itself in the Plato cave, continuing to enjoy, out of centuries-old habit, simple images of the truth but being educated by photographs is not like having been educated by older and more handcrafted images: today there are much more numerous images that require our attention; inventory began in 1839 and since then almost everything has been photographed, or at least so it seems; this insatiability of the photographic eye changes the conditions of captivity in that cave that is our world; teaching us a new visual code, photographs alter and expand our notions of what is worth watching and what we have the right to observe; the greatest consequence of photography is that it gives us the feeling that we can have the whole world in our head, like anthology of images…
