Henry Ford believed the soul of a person is located in their last breath and so captured the last breath of his best friend Thomas Edison in a test tube and kept it evermore. It is on display at the Henry Ford Museum outside Detroit, like Galileo’s finger in the church of Santa Croce, but Edison’s last breath is an invisible relic.
Edison was by far the most successful and, probably, the last exponent of the purely empirical method of investigation. Everything he achieved was the result of persistent trials and experiments often performed at random but always attesting extraordinary vigor and resource. Starting from a few known elements, he would make their combinations and permutations, tabulate them and run through the whole list, completing test after test with incredible rapidity until he obtained a clue. His mind was dominated by one idea, to leave no stone unturned, to exhaust every possibility.
When we set about accounting for a Napoleon or a Shakespeare or a Raphael or a Wagner or an Edison or other extraordinary person, we understand that the measure of his talent will not explain the whole result, nor even the largest part of it; no, it is the atmosphere in which the talent was cradled that explains; it is the training it received while it grew, the nurture it got from reading, study, example, the encouragement it gathered from self-recognition and recognition from the outside at each stage of its development: when we know all these details, then we know why the man was ready when his opportunity came.
The recurrence of a phenomenon like [Thomas] Edison is not very likely. The profound change of conditions and the ever increasing necessity of theoretical training would seem to make it impossible. He will occupy a unique and exalted position in the history of his native land, which might well be proud of his great genius and undying achievements in the interest of humanity.
As Edison is credited with saying, "Opportunity is missed by most people because it is dressed in overalls and looks like work." We all want to be successful, but most of us aren't willing to do what those who are successful did to attain it. We want success without sacrifice, but you can't have one without the other!
If he [Thomas Edison] had a needle to find in a haystack, he would not stop to reason where it was most likely to be, but would proceed at once with the feverish diligence of a bee, to examine straw after straw until he found the object of his search. … Just a little theory and calculation would have saved him ninety percent of his labor.
I came from Paris in the Spring of 1884, and was brought in intimate contact with him [Thomas Edison]. We experimented day and night, holidays not excepted. His existence was made up of alternate periods of work and sleep in the laboratory. He had no hobby, cared for no sport or amusement of any kind and lived in utter disregard of the most elementary rules of hygiene. There can be no doubt that, if he had not married later a woman of exceptional intelligence, who made it the one object of her life to preserve him, he would have died many years ago from consequences of sheer neglect. So great and uncontrollable was his passion for work.
