'In philosophizing we may not terminate a disease of thought. It must run its natural course, and slow cure is all important. (That is why mathematicians are such bad philosophers.)'
'Popeye is still very much alive in oral tradition, but for some reason he chiefly features in verses which are obscene.'

Appropriateness - necessity - complexity - metaphorical overtones.
III Metaphor and Other Figures of Speech

Instinctive: the essay - required effect - exordium.
Constructional: scaffolding - the novel.
Part II: Rhetoric
