The person, furthermore, because of his particular class affiliation, with the attainment in the way of skill and insight which this imparts, is always naturally under constraint not merely to overcome the specialism, but also to apply the special training beyond the immediate sphere of its development to all sides of the nature that is within him. Out of the depth and breadth of his personal character, bounded only by the unity of experience, he must ever react against the narrowness and the factional ritual, and taking this ritual--or special professional technique--to be valid mediately rather than immediately, in spirit rather than merely in letter, must ever seek to translate his factional experience, its skill and its insight, to all parts of human life. Only so can he be true both to his special classification and to his personal wholeness. But an insistent question: Is such translation possible? On the possibility the case for either personality or a class-divided society must finally depend. On the possibility hangs also the worth of this case to the general argument of this book. Logically, there certainly can be but one answer, and that an affirmative one, since analogy, the primal condition of translation, must be universal [p.166] among the parts of any unity as well as between any part and the whole. No two parts, it is true, can be literal, prosaic reproductions of each other, but metaphors of each other all parts are bound to be, and any part and the whole must also have this relation of the metaphor, so that any acquired, more or less highly developed power of thought or action, however special and however technical, may and must have meaning throughout the whole life of the person or of humanity. Accordingly, with the acquired freedom of any part, the metaphors, relating part to part, may, if not must, flash to the remotest regions of the person's experience-world. The left hand, with its unconsciously developed power, of course usually unexercised, of mirror-writing, affords only a very crude illustration of what this implies, and a very imaginative illustration is in the flashing of the morning light as it reaches height after height of the beholder's outstretched world.
