In a sense Fuentes is a philosopher of revolution, and most of his novels deal with the subject to one extent or another. He plans to write a book featuring Emiliano Zapata, one of the heroes of the Mexican Revolution. At times Fuentes seems convinced that Latin American countries are doomed to repeat revolutionary warfare through all their history, obeying Nietzsche's law of eternal recurrence. Unlike Federico Robles and Artemio Cruz, Baltasar Bustos does not betray the cause for which he fought, but retains some of his idealism.
