_______ wrote to German revolutionary Karl Blind on 10 April 1865, "The progress of humanity seems to have come to a halt, and you with your superior intelligence will know why. The reason is that the world lacks a nation [that] possesses true leadership. Such leadership, of course, is required not to dominate other peoples but to lead them along the path of duty, to lead them toward the brotherhood of nations where all the barriers erected by egoism will be destroyed."
