knives
V
Not all the knives of the lamp-posts,
Nor the chisels of the long streets,
Nor the mallets of the domes
And high towers,
Can carve
What one star can carve,
Shining through the grape-leaves.
VI
Rationalists, wearing square hats,
Think, in square rooms,
Looking at the floor,
Looking at the ceiling.
They confine themselves
To right-angled triangles.
If they tried rhomboids,
Cones, waving lines, ellipses --
As, for example, the ellipse of the half-moon --
Rationalists would wear sombreros.
