Between the conception and the creation, between the invention and the innovation, falls the shadow.
Power runs between the two.
An idea without a bankroll is just an idea. In order for an invention to become an innovation the inventor must persuade someone with a bankroll. Joel Mokyr understands this perfectly well, and calls it 'openness to new information', He quotes a writer who contrasted the delightful stage of alertness with the less delightful stage of persuasion, which is 'a struggle against stupidity and envy, apathy and evil, secret opposition and open conflict of interests, the horrible period of struggle with man, a martyrdom even if success ensues'. Any academic or businessperson can supply instances. What matters, to put Mokyr's theme in rhetorical form, are the conditions for persuasion.
