Since ancient times, civilizations have reflected on the future of humanity, but few voices have done so with the depth and clarity of René Guénon. In The Reign of Quantity and the Signs of the Times, the author presents a relentless analysis of the spiritual collapse of the modern era and the West, drawing a parallel between the growing dominance of the quantitative and the decline of the qualitative values that once governed human life. In this astonishingly prophetic essay, Guénon exposes how the unbridled advance of technology and profane science have reduced the world to a material realm, where quantity prevails over quality and the sense of the sacred vanishes. Drawing on traditional sources ranging from Hindu metaphysics to Christian theology, the author reveals the signs of a final crisis in the cycle of humanity, which is inexorably advancing toward its culmination. For those seeking to understand the spiritual background of contemporary chaos, this work is essential reading, revealing a vision imbued with ancient wisdom. The relevance of its ideas, originally written in 1945, resonates even more strongly today, making it an indispensable text for apocalyptic times.
