Responding to the spectacle of postmodernism,
critical artists like Barbara Kruger, Jenny Holzer, and Hans
Haacke have adopted tactics of quotation, citation, and
appropriation that were pioneered some five decades earlier
in Benjamin's examination of international Dada and the
Russian futurists in such essays as "The Work of Art in the
Age of Mechanical Reproduction" and "The Artist as
Producer." The challenge that Benjamin laid down was
for every author to become a producer, every artist a
theorist, in the general remapping of generic boundaries,
aesthetic traditions, and cultural conventions that the age
demanded. Not incidentally, in photography this political
requisite entailed a subversion of "the barrier between
writing and image. What we require of the photographer,"
Benjamin insisted, "is the ability to give his picture the
caption that wrenches it from modish commerce and gives it a
revolutionary useful value. In thus linking
photographic activity to language and signification,
Benjamin's critique of photographic mimesis looks forward to
Roland Barthes' postwar argument that "the conventions of
photography . . . are themselves replete with signs."
In the age of mass communication, as Barthes would go on to
argue in the 1960s, every pictorial form is always already a
linguistic text.
