Your ideas are his ideas, your prejudices are his prejudices, your outlook is his outlook. In this way you achieve the congruence between your paper and the teacher's perusal of that paper, which will denote intelligence to him and a hence good grade for you. Organization is the supreme virtue, not for any abstruse reason, but because professors are usually very careless readers, and easily become inpatient. They must not be allowed to miss your points. The only way to hold their attention is by the most rigorous organization, including topic sentences at the beginning AND at the end of each paragraph.
Summaries are mandatory to capture the attention of dozing academic noggins.
If they miss it, it's you who lose. Words can be quite plain, in which condition they denote sincerity, or that can be fancied up a bit to infer higher intelligence. Academics do hate this situation. Second, fine writing may suggest to the teacher that you are plagiarizing, and whether you did or not, there is surely some passage in some book which may infer that you did. A determined professor with an axe to grind is a formidable hangman, even with a mixed metaphor.
