Poetry is a sort of inspired mathematics, which gives us equations, not for abstract figures, triangles, squares, and the like, but for the human emotions. If one has a mind which inclines to magic rather than science, one will prefer to speak of these equations as spells or incantations; it sounds more arcane, mysterious, recondite.
Ezra PoundNo picture is made to endure nor to live with but it is made to sell and sell quickly with usura, sin against nature, is thy bread ever more of stale rags is thy bread dry as paper.
Ezra PoundWith Usura With usura hath no man a house of good stone each block cut smooth and well fitting.
Ezra Pound
