Award-winning essay in philosophical anthropology meditating on who, in terms of history of ideas, modern western man was, is, and will perhaps become. The author focuses on developments of modern man’s self-knowledge, understood both as concept of his own human nature and as individual self-consciousness, made possible by the idea that each human being is an autonomous rational agent. The book examines how Selfhood and self-governed individuality connect to science and technology, and offers an imaginative exploration of various modern narratives of human singularity, from Robinson Crusoe to Zarathustra, and to contemporary individual Facebook profiles.
