abstract: The aim of this project is an exploration of health literacy as found in the papal encyclical Humanae Vitae. The rhetoric of the Catholic Church clearly demonstrates its creation and promotion of moral authority over the health practices of the faithful. As such, the encyclical illustrates the means by which Catholic conscience dictates corporal existence. Through its denunciation of the evolving social mores of the 1960s, its condemnation of contraception, and its encouragement in the reception of natural law, the document offers the merits of Catholic marriage as guiding principles beneficial to all good men. Ultimately, group morality is conveyed as the path to health. Consideration of Humanae Vitae through a Burkean logological lens allows an inquiry into the elements of theology and biology, and evaluates the foundational language of each as a form of action. As well, the oracular nature of the rhetoric merits analysis, for the Church continues to maintain the encyclical as the final declaration of sexual rectitude. However, many Catholics and members of secular society disagree, necessitating a forecast which questions the rhetorical retention of the text. / Dissertation/Thesis / Ph.D. English 2010
