If we examine the mental labors of men of genius to whom we owe discoveries which have opened new paths to thought, and have given us new sources of well-being and social progress, we shall have to admit that in themselves they cannot be described as extraordinary processes, inaccessible to mediocrity. "Genius coincides with the possession in a very high degree of the power of association by similarity. This is the essential quality of genius," says Bain. Even at the "central point" of discovery, it is only by accurate observation and a very simple process of reasoning, of which most persons would consider themselves capable, that the discovery is made. At most it is due to a marshalling of "evidences" which, however, passed unnoticed by all but the discoverer.
We may say that genius has the faculty of isolating a fact in the consciousness, and of so distinguishing it from all others that it is as if a single ray of light should fall upon a diamond in a dark room. This single idea, then, causes a complete revolution in the consciousness, and is capable of constructing something infinitely great and precious for all humanity.
But it is the intense significance of ordinary things, and not the abnormal, which is the main factor; it is the isolation in a homogeneous field, not the intrinsic value of the thing, which determines the marvelous phenomenon. Perhaps within countless thousands of chaotic perceptions the gem had existed, stored up amidst a multitude of useless and cumbrous objects, and had never succeeded in arresting attention; meanwhile inertia continued to allow new objects to penetrate continually within the distended and impotent walls. After a discovery, many will perceive that they themselves held the same truth within them; but in this case it is not the truth itself that has value, but the man who is capable of appreciating it and bringing it into relation with action.
But very often it is not the case that the newly discovered truth already exists in the chaos of obscure consciousness; and then the new light, simple though it be, can find no way by which to penetrate into the mind.
It is rejected as something strange and fallacious; and a certain lapse of time is necessary, a certain coordination of the intelligence, to enable the "novelty" to enter. Yet some day it will be considered clear as crystal. It was not the "nature" of man which shrank from it, but his "errors." These errors not only make man incapable of production, but are in themselves hostile to receptivity. Thus it often happens that the pioneers of salvation are persecuted by a sort of unconscious ingratitude, which is the fruit of spiritual darkness.
What was the argument of Christopher Columbus? He thought: "If the earth is really round, he who starts from a certain point and advances steadily, will return to the point of departure." This was the sum of the intellectual work which enriched mankind with a new world.
That a great continent should have lain in the track of Columbus, and that he should have encountered this and not death, was the destiny due to the chance of environment. The environment sometimes rewards "small reasonings" of this kind in a surprising manner.
It was certainly not a great labor of human intelligence which brought about these great results; it was the triumph of this idea over the whole consciousness, and the heroic courage of the man, which gave it its value. The great difficulty, for the man who had conceived the idea, was to persevere until he could persuade others to help him in his enterprise, to give him ships and followers. It was the faith and not the idea of Columbus which triumphed.
That simple and logical reasoning kindled within him something infinitely more precious than intelligence, and enabled a single man of humble origin, and almost uneducated, to present a world to a queen.
