 De Kadt was a prodigiously productive – if often acerbic and polemical – writer who, at his best, was a writer of great elegance and style.Bart Tromp, an editor of a posthumously published collection of essays, referred to him as "an Orwell of Oss".In "Het fascisme en de nieuwe vrijheid", De Kadt predicts the coming of the Second World War, the ultimate defeat of Fascism and the emergence of the United States of America and the Soviet Union as the dominant global powers.
