In early 1940, just before he attempted to escape to Spain from Vichy France, the Marxist theorist and art critic Walter Benjamin penned his Theses on the Concept of History. In twenty numbered paragraphs, Benjamin sketches his vision of the task of the materialist historian. In contrast to the historicist, whose method consists of merely adding “a mass of facts, in order to fill up a homogeneous and empty time,” the materialist historian employs a “constructive” method (XVII), piecing together the “tradition of the oppressed” (VIII) from the rubble of the catastrophic past into a “constellation” (XVII) that most accurately reflects the fragmented character of modern reality.
