"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."
