“Sure as the most certain sure … plumb in the uprights, well entreated, braced in the beams, Stout as a horse, affectionate, haughty, electrical, I and this mystery we stand. Clear and sweet is my soul … and clear and sweet is all that is not my soul, Lack one lacks both … and the unseen is proved by the seen Till that becomes unseen and receives proof in its turn. To elaborate is no avail … Learned and unlearned feel that it is so.”
