 In her treatment of the novel , María Regina Ruiz claims that power gives its wielder the ability to make prohibitions ; prohibitions that are reflected in history , the study of which reveals what is and what is not told . The government 's actions in The Feast of the Goat demonstrate the discourse of prohibition : foreign newspapers and magazines were prohibited from entering Trujillo 's country as they were seen as a threat to the government 's ideas . Mario Vargas Llosa takes part in this discourse by recounting what was prohibited . Ruiz notes that writing also has the power to transform reality . It brings the reader back to the past , allowing the reader to comprehend myths or distorted stories told by historians . Ruiz contends that knowing the past is crucial to one 's understanding of the present that takes us to postmodernism , and argues that The Feast of the Goat can thus be seen as a postmodern discourse that gives power to history recreation . The construction of fictions surrounding the events of Trujillo 's regime allow a degree of freedom from the horrors that took places . Author Julia Alvarez contends that these events can only finally be understood by fiction , only finally be redeemed by the imagination  , while Richard Patterson claims that Vargas Llosa  reconfigures , and to a large degree demythologizes  Trujillo and his brutal reign through use of narrative structure . Vargas Llosa 's writing acts as a cathartic force for this period in history . fill in the blank  :  The construction of fictions surrounding the events of _________ 's regime allow a degree of freedom from the horrors that took places
