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.
