So something should be cut and the dullness should be cut. Bluntness that is, an absence of sharpness is associated with dullness. If a thing is very sharp, it doesn t hurt as much as a thing that is less sharp. To be hacked about by a thing that is not sharp is cruel, while being dealt with by something very sharp is comparatively merciful. So bluntness is against keenness.
Roundness is also against keenness.
Roundness is important, but where roundness is against the idea of point, it is a bad roundness, because we want to have the softness that roundness represents and the hardness that the point represents. This is a quite good poem. Looking at it, we find that various elements making for keenness are present. Since the universe is both wide and keen, sharp and soft, it is to be expected that language expressing the universe be also that. It is quite clear that a letter like the hard c is sharp in a way that z is not.
