Rhetoric completes the tools of learning. Dialectic zeros in on the logic of things, of particular systems of thought or subjects. Rhetoric takes the next grand step and brings all these subjects together into one whole.
William BlakeI turn my eyes to the schools & universities of Europe And there behold the loom of Locke whose woof rages dire, Washed by the water-wheels of Newton. Black the cloth In heavy wreaths folds over every nation; cruel works Of many wheels I view, wheel without wheel, with cogs tyrannic Moving by compulsion each other: not as those in Eden, which Wheel within wheel in freedom revolve, in harmony & peace.
William Blake
