  [00:05.30]Edison: Inventor of Invention Walter Lippmann
  [00:12.56]It is impossible to measure the importance of Edison
  [00:17.92]by adding up the specific inventions with which his name is associated.
  [00:23.67]Far-reaching as many of them have been in their effect upon modern civilization,
  [00:30.62]the total effect of Edison's career surpasses the sum of all of them.
  [00:37.38]He did not merely make the incandescent lamp
  [00:42.34]and the phonograph and innumerable other devices practicable for general use;
  [00:50.99]it was given to him to demonstrate the power of applied science so concretely,
  [00:57.65]so understandably, so convincingly that he altered the mentality of mankind.
  [01:06.12]In his lifetime,largely because of his successes,
  [01:11.47]there came into widest acceptance the revolutionary conception
  [01:18.03]that man could by the use of his intelligence
  [01:24.19]invent a new mode of living on this planet;
  [01:29.34]the human spirit,
  [01:32.60]which in all previous ages had regarded the conditions of lifeas
  [01:38.77]essentially unchanging and beyond man's control, confidently,
  [01:46.63]and perhaps somewhat naively,
  [01:51.31]adopted the conviction that anything
  [01:55.96]could be changed and everything could be controlled.
  [02:01.31]This idea of progress is in the scale of history a very new idea.
  [02:07.87]It seems first to have taken possession
  [02:12.31]of a few minds in the seventeenth and eighteenth centuries
  [02:18.16]as an accompaniment of the great advances in pure science.
  [02:24.82]It gained greater currency in the first half of the nineteenth century
  [02:31.20]when industrial civilization
  [02:35.14]began to be transformed by the application of steam power.
  [02:41.10]Edison supplied the homely demonstrations which insured
  [02:47.16]the popular acceptance of science,
  [02:52.02]and clinched the popular argument,which had begun with Darwin,
  [02:58.26]about the place of science in man's outlook upon life.
  [03:04.50]Thus he became the supreme propagandist of science
  [03:11.06]and his name the great symbol of an almost blind faith in its possibilities.
  [03:18.92]Thirty years ago, when I was a schoolboy,
  [03:23.57]the ancient conservatism of manwas still the normal inheritance of every child.
  [03:31.62]Perhaps these things would work. Perhaps they would not explode.
  [03:38.98]Perhaps it would be amusing to play with them.
  [03:44.44]Today every schoolboy not only takes all the existing inventions
  [03:51.81]as much for granted as we took horses and dogs for granted,
  [03:57.69]but also he is entirely convinced that all other desirable things
  [04:05.45]can and will be invented.
  [04:09.10]In my youth the lonely inventor
  [04:13.54]who could not obtain a hearing was still the stock figure of the imagination.
  [04:20.41]Today the only people who are not absolutely sure
  [04:25.87]that television is perfected are the inventors themselves.
  [04:32.22]No other person played so great a part as Edison
  [04:37.50]in this change in human expectation,and finally,
  [04:43.45]by the cumulative effect of his widely distributed inventions
  [04:50.51]plus a combination of the modern publicity technique
  [04:57.04]and the ancient myth-making faculty of men,
  [05:02.11]he was lifted in the popular imagination to a place
  [05:08.04]where he was looked upon not only as the symbol but as the creator of a new age.
  [05:16.08]In strict truth an invention is almost never the sole product of any one mind.
  [05:23.74]The actual inventor is almost invariably
  [05:29.20]the man who succeeds in combining and perfecting previous discoveries
  [05:36.46]insuch a way as to make them convenient
  [05:43.01]Edison had a peculiar genius for carrying existing discoveries
  [05:49.68]to the point where they could be converted into practicable devices,
  [05:56.52]and it would be no service to his memory,
  [06:01.06]or to the cause of sciencewhich he serves so splendidly,
  [06:06.92]to pretend that he invented by performing solitary miracles.
  [06:12.87]The light which was bom in his Laboratory at Menlo Park fifty-two years ago

  [06:20.03]was conceived in the antecedent experiments of many men in many countries
  [06:27.58]over a period of nearly forty years,
  [06:32.02]and these experiments in their turn were conceivable
  [06:36.98]only because of the progress of the mathematical
  [06:43.96]and physical sciencesin the preceding two centuries.
  [06:48.22]Because of Edison,more than of any other man,
  [06:53.68]scientific research has an established place in our society;
  [07:00.44]because of the demonstrations he made,
  [07:04.70]the money of taxpayers and stockholders has become available for studies
  [07:12.07]the nature of which they do not often understand,
  [07:17.24]though they appreciate their value
  [07:21.08]and anticipate their ultimate pecuniary benefits.
  [07:26.64]It would be a shallow kind of optimism
  [07:31.00]to assume that the introduction of the art of inventing
  [07:36.78]has been an immediateand unmixed blessing to mankind.
  [07:42.84]It is rather the most disturbing element in civilization,
  [07:48.30]the most profoundly revolutionary thing which has evei let loose in the world.
  [07:55.85]For the whole ancient wisdom of man is founded upon the conception of a life
  [08:03.29]which in its fundamentals chi imperceptibly if at all.
  [08:10.34]The effect of organized,subsidized inven
  [08:15.91]stimulated by tremendous incentives of profit,
  [08:21.55]and encouraged by an insatiable popular appetite for change,
  [08:27.92]is to set all the relation men in violent motion,
  [08:33.78]and to create overpowering problems faster than human wisdom
  [08:39.84]has as yet been able to assimilate them.
  [08:44.51]Thus the age we live in offers little prospect of outward stability,
  [08:51.07]and only those who by an inner serenity
  [08:56.42]and disentanglement
  [09:00.19]have learned how to deal with the continually unexpected can be at home in it.
  [09:07.55]It maybe rhat in time we shall become used to change
  [09:13.61]as in our older wisd we had become used to the unchanging.
