The Decline of the West (1918, 1923)
Context: The press to-day is an army with carefully organized arms and branches, with journalists as officers, and readers as soldiers. But here, as in every army, the soldier obeys blindly, and war-aims and operation-plans change without his knowledge. The reader neither knows, nor is allowed to know, the purposes for which he is used, nor even the role that he is to play. A more appalling caricature of freedom of thought cannot be imagined. Formerly a man did not dare to think freely. Now he dares, but cannot; his will to think is only a willingness to think to order, and this is what he feels as his liberty.
