The theme of this book is *the documentarian—*what the documentarian is and how we can understand it as a concept. Working from the premise that the documentarian is a special—extended—sign, the book develops a model of a quadruple sign structure for-and-of the documentarian, growing out of enduring traditions in philosophy, semiotics, psychoanalysis, and documentary theory. Dan Geva investigates the intellectual premise that allows the documentarian to show itself as an extremely sophisticated, creative, and purposeful being-in-the-world—one that is both embedded in its own history and able to manifest itself throughout its entire documentary life project, as a stand-alone conceptual phase in the history of ideas.
