It is true a man (a silly man) might make change itself his object or ideal. But as an ideal, change becomes unchangeable. If a change-worshiper wishes to estimate his own progress he must be sternly loyal to the ideal of change; he must not begin to flirt gaily with the idea of monotony. Progress itself cannot progress. It is worth a remark in passing, that when Tennyson, in a wild and rather weak manner, welcomed the idea of infinite alteration in society, he instinctively took a metaphor which suggests an imprisoned tedium. He wrote—Let the great world spin forever down the ringing grooves of change. He thought of change itself as an unchangeable groove; and so it is. Change is about the narrowest and hardest groove a man can get into.
I wonder if Barack Obama has ever read Chesterton?
UPDATE: Here is a good analysis of the "changes" Obama seeks.
