. ①Zora Neale Hurston's 1942 autobiography,
Dust Tracks on a Road, has received some of the most negative criticism of any of Hurston's books. ②Among critics' complaints—some from Hurston's warmest admirers-is the work's fragmentary nature, a nature which, while present in other Hurston texts, including the universally acclaimed novel
Their Eyes Were Watching God, is particularly conspicuous in
Dust Tracks. ③The complaints about Dust Tracks are valid if one insists on the cardinal conventions of autobiography: traditional autobiographical structure and formal organization, and a focused projection of the autobiographical persona. ④But
Dust Tracks portrays a persona that resists reduction to a coherent unity—a person of many moods who is in tension with the world in which she moves. ⑤In order to correspond better to this persona,
Dust Tracks focuses on the fragmented life of Hurston's imagination: the psychological dynamics of her family, community stories, and characters of friends.
