Looking at the breadth of Joan Didion's writing, from journalism, essays, fiction, memoir and screen plays, it may appear that there is no unifying thread, but Matthew R. McLennan argues that 'the ethics of memory' - the question of which norms should guide public and private remembrance - offers a promising vision of what is most characteristic and salient in Didion's works.By framing her universe as indifferent and essentially precarious, McLennan demonstrates how this outlook guides Didion's reflections on key themes linked to namely witnessing and grieving, nostalgia, and the paradoxically amnesiac qualities of our increasingly archived public life that she explored in famous texts like Slouching Towards Bethlehem , The Year of Magical Thinking and Salvador . McLennan moves beyond the interpretive value of such an approach and frames Didion as a serious, iconoclastic philosopher of time and memory.Through her encounters with the past, the writer is shown to offer lessons for the future in an increasingly perilous and unsettled world.
