Well-known in the French-speaking world for his devastating critiques of the decadence of thought in the West since Descartes's Cogito ergo sum, Marcel De Corte published Intelligence in Danger of Death as the final stage of his reflections in 1969. To grasp the profound mutation which man and society have undergone, Marcel De Corte offers a merciless analysis that relies on classical philosophy and insight from Christian Revelation. He outlines the genealogy of contemporary evils and indicates the ways to correct these. What Orwell and Huxley turned into novels, Marcel De Corte predicted through reasoning and analysis in the light of Wisdom. His thesis: man's speculative and practical intelligence has been replaced with his working intelligence, that is, the intelligence that produces new things and can only know the world that it has produced. This is how man has ultimately become detached from reality and how his mind has become apt only to grasp a manufactured world as presented to him by those in command of the production of information: scientists, media, governments.
