Genius is intensity. Abraham Lincoln possessed such power of concentration that he could repeat quite correctly a sermon to which he had listened in his boyhood. Dr. O. W. Holmes, when an Andover student, riveted his eyes on the book he was studying as though he were reading a will that made him heir to a million.
A New York sportsman, in answer to an advertisement, sent twenty-five cents for a sure receipt to prevent a shotgun from scattering, and received the following; "Dear Sir: To keep a gun from scattering put in but a single shot."
It is the men who do one thing in this world who come to the front. Who is the favorite actor? It is a Jefferson, who devotes a lifetime to a "Rip Van Winkle," a Booth, an Irving, a Kean, who plays one character until he can play it better than any other man living, and not the shallow players who impersonate all parts. It is the man who never steps outside of his specialty or dissipates his individuality. It is an Edison, a Morse, a Bell, a Howe, a Stephenson, a Watt. It is Adam Smith, spending ten years on the "Wealth of Nations." It is Gibbon, giving twenty years to his "Decline and Fall of the Roman Empire." It is a Hume, writing thirteen hours a day on his "History of England." It is a Webster, spending thirty-six years on his dictionary. It is a Bancroft, working twenty-six years on his "History of the United States." It is a Field, crossing the ocean fifty times to lay a cable, while the world ridicules. It is a Newton, writing his "Chronology of Ancient Nations" sixteen times. It is a Grant, who proposes to "fight it out on this line if it takes all summer." These are the men who have written their names prominently in the history of the world.
A one-talent man who decides upon a definite object accomplishes more than the ten-talent man who scatters his energies and never knows exactly what he will do. The weakest living creature, by concentrating his powers upon one thing, can accomplish something; the strongest, by dispersing his over many, may fail to accomplish anything. Drop after drop, continually falling, wears a passage through the hardest rock. The hasty tempest, as Carlyle points out, rushes over it with hideous uproar and leaves no trace behind.
A great purpose is cumulative; and, like a great magnet, it attracts all that is kindred along the stream of life.
A Yankee can splice a rope in many different ways; an English sailor only knows one way, but that is the best one. It is the one-sided man, the sharp-edged man, the man of single and intense purpose, the man of one idea, who turns neither to the right nor to the left, though a paradise tempt him, who cuts his way through obstacles and forges to the front. The time has gone forever when a Bacon can span universal knowledge; or when, absorbing all the knowledge of the times, a Dante can sustain arguments against fourteen disputants in the University of Paris, and conquer in them all. The day when a man can successfully drive a dozen callings abreast is a thing of the past. Concentration is the keynote of the century.
Scientists estimate that there is energy enough in less than fifty acres of sunshine to run all the machinery in the world, if it could be concentrated. But the sun might blaze out upon the earth forever without setting anything on fire; although these rays focused by a burning-glass would melt solid granite, or even change a diamond into vapor. There are plenty of men who have ability enough; the rays of their faculties, taken separately, are all right, but they are powerless to collect them, to bring them all to bear upon a single spot. Versatile men, universal geniuses, are usually weak, because they have no power to concentrate their talents upon one point, and this makes all the difference between success and failure.
Chiseled upon the tomb of a disappointed, heart-broken king, Joseph II. of Austria, in the Royal Cemetery at Vienna, a traveler tells us, is this epitaph: "Here lies a monarch who, with the best of intentions, never carried out a single plan."
Sir James Mackintosh was a man of remarkable ability. He excited in every one who knew him the greatest expectations. Many watched his career with much interest, expecting that he would dazzle the world. But there was no purpose in his life. He had intermittent attacks of enthusiasm for doing great things, but his zeal all evaporated before he could decide what to do. This fatal defect in his character kept him balancing between conflicting motives; and his whole life was almost thrown away. He lacked power to choose one object and persevere with a single aim, sacrificing every interfering inclination. He vacillated for weeks trying to determine whether to use "usefulness" or "utility" in a composition.
One talent utilized in a single direction will do infinitely more than ten talents scattered. A thimbleful of powder behind a ball in a rifle will do more execution than a carload of powder unconfined. The rifle-barrel is the purpose that gives direct aim to the powder, which otherwise, no matter how good it might be, would be powerless. The poorest scholar in school or college often, in practical life, far outstrips the class leader or senior wrangler, simply because what little ability he has he employs for a definite object, while the other, depending upon his general ability and brilliant prospects, never concentrates his powers.
