Sir Humphrey Davy found in Franklin's scientific papers a language lucid and decorous, "almost as worthy of admiration as the doctrine"[i-160] they contain. S. G. Fisher buoyantly maintained that Franklin's "is the most effective literary style ever used by an American." After reading Franklin's paper on stoves he was "inclined to lay down the principle that the test of literary genius is the ability to be fascinating about stoves."[i-161] Whether he writes soberly (albeit tempered by Gallic fancy) of the mutability of life, as in _The Ephemera_, or of sophisticated social amenities, as in the letters to Madame Brillon and Madame Helvétius, or in his memoirs, in which solid fact follows solid fact, sifted by the years of good fortune, Franklin's style never loses its compelling charm and vigor. If he never wrote (or uttered) less than was demanded by the nature of his subject, neither would he have disgusted the Clerk of Oxenford who Nought o word spak he more than was nede. He was no formal literary critic such as Boileau, Lessing, or Coleridge, and no acknowledged arbiter of taste, such as Dr. Johnson. Yet Franklin, in voluminous practice, enjoying tremendous international vogue, proved that his theories bore the acid test of effectiveness. Indirectly he challenged his readers to honor principles of rhetoric which could so trenchantly serve the demands of his catholic pen, and make him one of the most widely read of all Americans. IV. FRANKLIN AS PRINTER AND JOURNALIST Franklin was a printer chiefly because of two proclivities which were basic in his personality from childhood to old age--a bent toward practical mechanics ("handiness") and a fondness for reading (bookishness). Further, he was a journalist and publisher chiefly because he was a printer. A thorough printer is both an artisan and an artist; he has both the manual dexterity of a good workman and the aesthetic appreciation of the amateur of beauty. Franklin always took pride in his ability to handle the printer's tools, from the time when, at the age of twelve, he became "a useful hand"[i-162] in the print shop of his brother James, until the very end of his life. One of the pleasantest anecdotes of the old printer is that which tells of his visit to the famous Didot printing establishment in Paris, when he stepped up to a press, and motioning the printer aside, himself took possession of the machine and printed off several sheets. Then the American ambassador smiled at the gaping printers and said, "Do not be astonished, Sirs, it is my former business."[i-163]
