Famous quotes containing the word terms:
“The mystic purchases a moment of exhilaration with a lifetime of confusion; and the confusion is infectious and destructive. It is confusing and destructive to try and explain anything in terms of anything else, poetry in terms of psychology.”
—Basil Bunting (1900–1985)
