I passed on to the next necessity of any ideal of progress. Some people (as we have said) seem to believe in an automatic and impersonal progress in the nature of things. But it is clear that no political activity can be encouraged by saying that progress is natural and inevitable; that is not a reason for being active, but rather a reason for being lazy. If we are bound to improve, we need not trouble to improve. The pure doctrine of progress is the best of all reasons for not being a progressive. But it is to none of these obvious comments that I wish primarily to call attention. The only arresting point is this: that if we suppose improvement to be natural, it must be fairly simple. The world might conceivably be working towards one consummation, but hardly towards any particular arrangement of many qualities. To take our original simile: Nature by herself may be growing more blue; that is, a process so simple that it might be impersonal. But Nature cannot be making a careful picture made of many picked colours, unless Nature is personal. If the end of the world were mere darkness or mere light it might come as slowly and inevitably as dusk or dawn. But if the end of the world is to be a piece of elaborate and artistic chiaroscuro, then there must be design in it, either human or divine. The world, through mere time, might grow black like an old picture, or white like an old coat; but if it is turned into a particular piece of black and white art-- then there is an artist. If the distinction be not evident, I give an ordinary instance. We constantly hear a particularly cosmic creed from the modern humanitarians;
