"The interest of the Protocols is their bearing on the questions: Have the Jews an organized world system? What is its policy? How is it being worked? These questions all receive full attention in the Protocols. Whosoever was the mind that conceived them possessed a knowledge of human nature, of history and of statecraft which is dazzling in its brilliant completeness, and terrible in the objects to which it turns its powers. If indeed one mind alone conceived them. It is too terribly real for fiction, too well sustained for speculation, too deep in its knowledge of the secret springs of life for forgery. Jewish attacks upon it thus far make much of the fact that it came out of Russia. That is hardly true. It came by way of Russia."
