“A text does not fully or unambiguously display its history—even the most insightful of interpretations and analyses are only likely to recover some elements of its fuller history, to notice some textual features that allow for uncertain guesses about their origins…All writing draws on writers’ knowledge, beliefs, and practices, built up through experiences of socially and historically situated life events. Writers themselves are only very partially aware of the many debts they owe to these intertextual and intercontextual influences,” (171).
