Note 240 — XX
Reading edition
There is no evidence that Gutenberg had been taught xylography, or any of the many branches of book-making. He was not, for that reason, incompetent to invent an entirely new branch. The history of great inventions shows that many inventors never received a thorough technical instruction in the arts or trades which they undertook to reconstruct. Jacquard, inventor of the automatic loom, was, in his boyhood, a bookbinder and a type-founder. Arkwright, inventor of the spinning jenny, was a barber until he was thirty years of age. Stephenson, inventor of the locomotive, tended a steam boiler, but had not served time as a machinist nor as a carriage-builder. Fulton, inventor of the steamboat, was not a sailor, machinist nor ship-builder. Morse, inventor of the electric telegraph, was an artist, not a mechanician, nor even a man of science. Koning, inventor of the cylinder printing machine, was not a printer. The greatest inventions have been made by men not within, but without, the arts they improved. It would seem that a thorough technical education in any art or trade cramps the inventive faculties, disqualifying the expert from making any attempt at radical changes, permitting him to attempt improvement in the details only.
