Nihilism is a popular and heavily studied topic which is prominently displayed in Javier Marí­as' novel Berta Isla. In this article, both Nietzschean and Heideggerian concepts of nihilism will be identified and analyzed within the context of Marí­­as's novel. Through textual analysis, the origin of nihilism will be explored as it relates to the will to power and valuative schema of the individual. It will be suggested that nihilism stems from valuative thinking induced by the herd-mentality of a community and that the fulfillment of such is the acceptance of absolute truth grounded in being and becoming.
