Medium specificity is the critical doctrine, articulated most forcefully by Clement Greenberg in the 1940s and extended by Michael Fried in the 1960s, that every art form has essential properties proper to its medium and should explore those rather than borrow effects from other media. For painting that meant flatness and the shape of the support; for sculpture, literal three-dimensional presence. The doctrine shaped how modernist painting was valued (Greenberg praised works that admitted their own flatness) and framed the great minimalism debate - Fried's Art and Objecthood (1967) attacked 'theatrical' objecthood against optical art. By the 1990s Rosalind Krauss declared a 'post-medium condition' of pluralism. As an aesthetic the doctrine lives on wherever critics ask what a medium is uniquely good at.
