The exaggeration which this rhetorician employs is not caricature but prophecy; and it would be a fair formulation to say that true rhetoric is concerned with the potency of things. The literalist, like the anti-poet described earlier, is troubled by its failure to conform to a present reality. What he fails to appreciate is that potentiality is a mode of existence, and that all prophecy is about the tendency of things. The discourse of the noble rhetorician, accordingly, will be about real potentiality or possible actuality, whereas that of the mere exaggerator is about unreal potentiality. Naturally this distinction rests upon a supposal that the rhetorician has insight, and we could not defend him in the absence of that condition. But given insight, he has the duty to represent to us the as yet unactualized future. It would be, for example, a misrepresentation of current facts but not of potential ones to talk about the joys of peace in a time of war. During the Second World War, at the depth of Britain’s political and military disaster, Winston Churchill likened the future of Europe to “broad sunlit uplands.” Now if one had regard only for the hour, this was a piece of mendacity such as the worst charlatans are found committing; but if one took Churchill’s premises and then considered the potentiality, the picture was within bounds of actualization. His “exaggeration” was that the defeat of the enemy would place Europe in a position for long and peaceful progress. At the time the surface trends ran the other way; the actuality was a valley of humiliation. Yet the hope which transfigured this to “broad sunlit uplands” was not irresponsible, and we conclude by saying that the rhetorician talks about both what exists simply and what exists by favor of human imagination and effort.[16]
