"The Revolt of the Masses" is an influential guide by the Spanish philosopher José Ortega y Gasset, which addresses the social upheaval in Europe at the beginning of the 20th century. In this work, the concept of the 'mass man' is examined, describing mass culture and analyzing its influence on modern life. Ortega y Gasset highlights how mass movements and the associated changes shape society and individual thinking. The author offers a critical perspective on the challenges that come with the dominance of mass culture and encourages reflection on the role of the individual in an increasingly homogenized world. This book is significant not only for those interested in philosophy and social sciences but also for anyone looking to understand the dynamics of modern society.
