The book "The End of Modernity / Power" by Romano Guardini offers a profound analysis of the societal and cultural changes that characterize the end of modernity. Guardini, one of the first thinkers of his generation, addresses the transition from a belief in progress to a cultural pessimism that points to the limits of humanity. In his essay, the question of power and its abuse in the post-war period is raised, particularly in the context of the experiences of National Socialism. The author calls for a critical engagement with power and its limits to preserve humanity in its essence. This work is significant not only for those interested in philosophy and religion but also encourages reflection on current societal challenges.
