A bit of frustration

More than halfway through the semester, I find myself a bit frustrated. This frustration comes from my inability to see Ottoman history from multiple perspectives. Despite the unique approach offered in class, I find myself reverting to the old teachings of Western textbooks. Specifically, the notion that the Ottomans were the so-called "sick man of Europe". I usually consider myself to be a very open-minded student of history, always seeking to explore alternate approaches. I also have a great deal of respect for the Ottomans. My studies have led me to believe that had the Ottomans captured Vienna, they would have gone on to take the rest of Europe. So I don't think it is a lack of respect for the Ottomans that leads me to question their abilities during the late part of their existence. I truly believe the Ottomans were enlightened, but I am convinced that the reforms of the 19th Century were defensive mechanisms, not forward-looking. I only question this because it seems so many in our class agree with this idea. I suppose the best thing i can do it consult more readings related to the subject. If anyone has a book that can show me a side of the Ottoman empire not usually covered in high school classrooms, please direct me to it. I would be extremely interested in understanding both sides of the argument.
