I am currently in a PhD program in History, but I have long realized that my real passion is for literature and languages and that I cannot see myself as a professional historian. Part of this decision was sparked when a professor of history advised me not to refer to some of my favorite poets in a paper, even though these references were quite appropriate to my argument. There is a professor in Comparative Lit. in Boston who has urged me on a number of occasions to apply to his institution. When I told this professor I was going to apply he was happy and assured me that he would give it the utmost attention. In other words, I have a great shot of getting in.
After submitting his recommendation for this application, my professor told me that he had voiced serious misgivings in his letter. The misgivings were twofold: 1.) he thought the professor who advised me away from literary references was wrong to do so, which means I am basing my decision to apply elsewhere on misinformation and 2.) he thinks I can do the same project I plan to do at the other institution where I am now with the comp. lit. professor as an external adviser. He also said that the department would hate to lose me. This, according to him, would be the "best of both worlds." Personally, I think that these misgivings are, at least partly, motivated by departmental territoriality on his part and also partly by his lack of knowledge about how serious I actually am in my vocational questions.
My query has two parts. First, I would like to know, generally speaking, how much weight recommendations carry with respect to the whole package (I know this is an impossible question to answer). Second, I want to know if my professor's misgivings seem to be a deal-breaker. I know this professor thinks very highly of my work and wants me to stay, so the misgivings were not directed at me or the quality of my work but at my motivation and the conditions under which I applied.
All other parts of my app. are in top condition: very high GRE scores, 2 forthcoming publications, two other good recs., many international conferences, and so forth. Given the whole app. and the professor at the receiving school and his avowed support, what weight do you think my professor's recommendation will hold among all the other considerations?
Thanks for your help!
