The ladder whose ascent implies spiritual progress has a long pedigree.  Hebrews, Greeks and Christians all gave special value to the heights, and Western morality tends to put all better things up high and worse things down low. By the last century growth became inexorably caught in this ascensionist fantasy. Darwin’s thesis The Descent of Man became, in our minds, the ascent of man. Each immigrant moved upward in social class as buildings moved upwards with their elevators to more expensive levels. By now the upward idea of growth has become a biographical cliché. To be an adult is to be a grown-up. Yet this is merely one way of speaking of maturity, and an heroic one at that. For even tomato plants and the  tallest trees send down roots as they rise toward the light. Yet the metaphors for our lives see mainly the upward part of the organic motion.
