Don’t misunderstand. One ain’t more valuable or important than the other. They’re simply different. Knowing it is the key to know what we’re to write. We can’t satisfy if we don’t know which to use. Feeling is heavy and will miserably sink a light easygoing piece to lift up spirits. Sentimentality will vanish overnight in a “master piece of world Literature”. What is it that you write? The first requires the reader to do your job and mastery to get them to do it. The second, to guide the reader. Neither requires less work than the other.
