In 2013 he became known to the public through his Spiegel bestseller “Why There is no World”. The book has been translated into many languages and has become a best-seller in Japan, among others. The Ullstein publishing house recently published "The Sense of Thought", in which Gabriel deals with digitization and artificial intelligence issues, as well as the philosophical foundations of ethics for society in the 21st century. Among other things, he has given interviews and written articles for Der Spiegel, Die Zeit, Frankfurter Allge-meine Zeitung, Süddeutsche Zeitung and Die Welt.
He is the creator of a new philosophical current called the new German realism, in opposi-tion to the old realism, materialism and postmodernism, the latter which he qualifies as a variant of constructivism.
As a fascinating speaker, he introduces the world of philosophical thought that we all face in one form or another, and connects this with the great social issues of our time. He is in demand as a speaker at conferences around the world and has given several lectures on topics such as AI and the future of work at the economic summit of the Süddeutsche Zeitung.
He speaks nine languages: English, German, Italian, Portuguese, Spanish, French, Chinese, Ancient Greek, Latin, and Biblical Hebrew.
