There is a "matching" issue existing between professors/students and the dynamics in the classroom is not purely determined by either. In other words, neither students or the professor can completely control the style of that particular class.
My personal suggestion regarding the lack of inner logic is 1) following him/her up in class no matter what and 2) build up your own logic tree after class. BTW, talking to the professor will help some time, but I'm totally aware how strong headed even stubborn some professors can be.
