From page 44 of An Alternate Style: Options in Composition:
I, for example, try to capture each day some of the moods/events/thoughts/insights that I have experienced—and though some of my “material” may benefit from a Grammar A articulation, a good deal of it would be robbed of its vitality and immediacy if I did not write it down in Grammar B. Much of my journal writing is creative—not “arty,” not the creative of “creative writing class”—but the creative of immediate unhampered recollection, expression, outpouring—and that creative confrontation of the days of my life more freely comes into existence through Grammar B verbalization than through Grammar A verbalization. That’s what my psyche tells me at least. And I am willing to go along with it.
