The relentless failure of Bouvard and Pécuchet to learn anything from their adventures raises the question of what is knowable. Whenever they achieve some small measure of success (a rare occurrence), it is the result of unknown external forces beyond their comprehension. In this sense, they strongly resemble Anthony in "The Temptation of Saint Anthony", a work which addresses similar epistemological themes as they relate to classical literature. Lionel Trilling wrote that the novel expresses a belief in the alienation of human thought from human experience. The worldview that emerges from the work, one of human beings proceeding relentlessly forward without comprehending the results of their actions or the processes of the world around them, does not seem an optimistic one. But given that Bouvard and Pécuchet do gain some comprehension of humanity's ignorant state (as demonstrated by their composition of the "Dictionary of Received Ideas"), it could be argued that Flaubert allows for the possibility of relative enlightenment.
