From 1200 to 1800 A.D. the population of the Western World remained almost constant. In the last 100 years in Europe and America the population has tripled in numbers. Out of this has arizen the phenomenon of the mass-man.
Can Western culture survive the encroachments of the mass-man? Can republican institutions survive this chaotic democracy? These are the problems to which Ortega's book seeks a realistic solution.
"What Rousseau's 'Contrat Social' was for the eighteenth century and Karl Marx's 'Das Kapital' was for the nineteenth, Senor Ortega's 'Revolt of the Masses' should be for the twentieth century." (Atlantic Monthly)
