Photographs are often invoked as an aid to understanding and tolerance. In
humanist jargon, the highest vocation of photography is to explain man to man.
But photographs do not explain; they acknowledge. Robert Frank was only being
honest when he declared that βto produce an authentic contemporary document, the
visual impact should be such as will nullify explanation.β If photographs are
messages, the message is both transparent and mysterious. βA photograph is a
secret about a secret,β as Arbus observed. βThe more it tells you the less you
know.β Despite the illusion of giving understanding, what seeing through
photographs really invites is an acquisitive relation to the world that
nourishes aesthetic awareness and promotes emotional detachment.
