Words, words, words. Francis Bacon said that "words are wise men's counters", but he was talking of a language that he hoped to purge of its deceptions. He was an early logical positivist, but not above the use of vicious emotive rhetoric when it suited his turn. In the Four Quartets Eliot said that "words slip and slide". Milton, another rhetorician, spoke of "calumnious art of counterfeited truth". Milton's Satan, confronting the Archangel, grandiloquently proclaims: "err not that so shall end The strife which thou call'st evil but we style The strife of glory."
