“The Seeds of Invention”
Sir William Armstrong maintains, as a half-truth, that Invention is the fruit of the circumstances that call for it almost more than of the mind from which it springs. In a sense it is true, as Sir William Armstrong says, that “the seeds of invention exist, as it were, in the air, ready to germinate whenever suitable conditions arise;” but it depends not the less on the genius of individual inventors to determine whether the germination shall happen in one century or the next. The history of the locomotive is itself the strongest argument against relying too much on these floating seeds of invention and favouring circumstances, and taking too little account of inventors. If the Killingworth brakesman had died in his youth, it is scarcely too much to say that we should probably not yet be travelling by steam. We owe it to George Stephenson’s keen insight and resolute temper that the locomotive was forced upon an unbelieving world, no one can say how long before circumstances would otherwise have called it into existence. The seed had been floating, it is true, and had been in a manner detected centuries before; but it remained without life, not because the occasion had not called it forth, but because the right man had not arisen.
