The statement about Scott's refusal comes from the 1911 Britannica article, and the evaluation there does sound rather negative and some other points of view would be useful, and indeed another has been added, but the Hayley quote would be an interesting addition as well if you have a source (book, article, authoritative web page) for it.  Advice on making your additions:  provide a verifiable citation for statements you make following the examples already in the article.  If you don't have a verifiable citation, it is probably best to leave the statement here on the talk page until one is found.  You may have to do minor edits to the other text to make your new text fit in.  Do your best, but if it's not perfect I'm sure someone else will give their attention to it at some point.  Don't let imperfection prevent a verifiable addition that is worthwhile in your eyes.  Look at the Help pages for more advice.
