I will only mention that the independent power of words to affect the writing of history is a thing to be watched out for. They have an almost frightening autonomous power to produce in the mind of the reader an image or idea that was not in the mind of the writer. Obviously they operate this way in all forms of writing, but history is particularly sensitive because one has a duty to be accurate, and careless use of words can leave a false impression one had not intended.
