In addition to the studies of Arguedas and Flaubert, Vargas Llosa has written literary criticisms of other authors that he has admired, such as Gabriel García Márquez, Albert Camus, Ernest Hemingway, and Jean-Paul Sartre. The main goals of his non-fiction works are to acknowledge the influence of these authors on his writing, and to recognize a connection between himself and the other writers; critic Sara Castro-Klarén argues that he offers little systematic analysis of these authors' literary techniques. In "The Perpetual Orgy", for example, he discusses the relationship between his own aesthetics and Flaubert's, rather than focusing on Flaubert's alone.
