Hi Jason, Usually writers take two directions when writing something A.Informative or B.Persuasive. I f I were writing a book on a subject that may be contradicting or controversial than I would need a plausible case with plausible evidence to support my book. Of course when someone posts on a public forum they have evidence to support their conculsion it is only natural for us all to ask for the evidence to see if it makes any sense. Mr. Silver in one of my links proposed a plausible theory to how Taijiquan came to be with evidence that supports his theory at least enough to entertain the idea that maybe another family had a hand in its creation. Credentials do carry weight in writing and publishing a book which is why on most martial art books the back lists the authors experience. Many people turn to books as a source of authority because to be honest if you are writing a book on the subject your authority on that subject should be on an academic level of understanding of the material. I think connecting the Chinese idea of Qi and the Dantian with Ki and the Hara in the Chinese internal arts and the Japanese arts and using Qigong and Kokyu in Taijiquan and Aikido or Daito ryu might make your conclusion more sound. However your posts and what little evidence you have presented is just not enough to draw a plausible conclusion to the theory you have present. It is the authors job to provide enough support in his or her arguement or thesis for the reader or audience. I really look forward to the book who knows maybe it will be your first draft and with some critques maybe your second edition could be one worth proud of. My English professor in college use to say"Don't worry about your first draft to much its going to be garbage anyway, its just there to get the kinks out"
