The spirit of the case
Judy Fiskin says that Walker Evans succeeded where his FSA boss Roy Stryker failed "because Evans settled for art. Stryker succumbed to the false promise of photography, strove to represent literally the world’s profusion, and inevitably produced a body of work whose scope seems puny compared to its model." Evans worked in a "more condensed, allusive, and circular manner."
Flannery O'Connor calls it "distortion," and TS Eliot says that it's "pressure" that distinguishes art from experience, and creates a new thing in the world. And in fact, it's this artifice that, according to Michael Chabon, "makes explicit... the yearning... to analogize the world, and at the same time frankly emphasizes the limitations, the confines, of [our] ability to do so.”
