The Revolt of the Masses by José Ortega y Gasset
In this work, Ortega traces the genesis of the "mass-man" and analyzes his constitution en route to describing the rise to power and action of the masses in society. Ortega is throughout quite critical of both the masses and the mass-men of which they are made up, contrasting "noble life and common life" and excoriating the barbarism and primitivism he sees in the mass-man.
