This book delves into the philosophical ideas of Nicolas Berdyaev, a Russian thinker whose concepts of personalism and the divine-humanity of man profoundly influenced religious thought in the 20th century. The author positions Berdyaev as a formidable critic of rationalistic theology, arguing that it has led to a distorted and exteriorized view of God and the human condition. Instead, Berdyaev emphasizes the existential and mystical experience of the divine, urging readers to seek communion with God through the depths of their own consciousness. This book presents Berdyaev's philosophy as a powerful antidote to the alienation and objectification prevalent in modern religious thought, offering a fresh perspective on the nature of humanity, freedom, and the ultimate purpose of existence.
