It was terribly humiliating to the people who had sacrificed everything for a national ideal. But the Congress was not interested in the private feelings of “subjects,” and the debate was closed. Did anybody object? Most assuredly. As soon as the first feeling of hatred against Napoleon had quieted down—as soon as the enthusiasm of the great war had subsided—as soon as the people came to a full realisation of the crime that had been committed in the name of “peace and stability” they began to murmur. They even made threats of open revolt. But what could they do? They were powerless. They were at the mercy of the most pitiless and efficient police system the world had ever seen. The members of the Congress of Vienna honestly and sincerely believed that “the Revolutionary Principle had led to the criminal usurpation of the throne by the former emperor Napoleon.” They felt that they were called upon to eradicate the adherents of the so-called “French ideas” just as Philip II had only followed the voice of his conscience when he burned Protestants or hanged Moors. In the beginning of the sixteenth century a man who did not believe in the divine right of the Pope to rule his subjects as he saw fit was a “heretic” and it was the duty of all loyal citizens to kill him. In the beginning of the nineteenth century, on the continent of Europe, a man who did not believe in the divine right of his king to rule him as he or his Prime Minister saw fit, was a “heretic,” and it was the duty of all loyal citizens to denounce him to the nearest policeman and see that he got punished. But the rulers of the year 1815 had learned efficiency in the school of Napoleon and they performed their task much better than it had been done in the year 1517. The period between the year 1815 and the year 1860 was the great era of the political spy. Spies were everywhere. They lived in palaces and they were to be found in the lowest gin-shops. They peeped through the key-holes of the ministerial cabinet and they listened to the conversations of the people who were taking the air on the benches of the Municipal Park. They guarded the frontier so that no one might leave without a duly viséd passport and they inspected all packages, that no books with dangerous “French ideas” should enter the realm of their Royal masters. They sat among the students in the lecture hall and woe to the Professor who uttered a word against the existing order of things. They followed the little boys and girls on their way to church lest they play hookey.
