Now, such persons undoubtedly represent a variation toward suggestibility of the most delicate and singular kind. They surpass the teachers from whom they learn. It is hard to say that they "learn to judge by the judgments of society." They so judge without seeming to learn, yet they differ from the man whose eccentricities forbid him to learn through the discipline of society. The two are opposite extremes of variation; that seems to me the only possible construction of them. It is the difference between the ice boat which travels faster than the wind and the skater who braves the wind and battles up-current in it. The latter is soon beaten by the opposition; the former outruns its ally. The crank, the eccentric, the enthusiast--all these run counter to sane social judgment; but the genius leads society to his own point of view, and interprets the social movement so accurately, sympathetically, and with such profound insight that his very singularity gives greater relief to his inspiration.
Now let a man combine with this insight--this extraordinary sanity of social judgment--the power of great inventive and constructive thought, and then, at last, we have our genius, our hero, and one that we well may worship! To great thought he adds balance; to originality, judgment. This is the man to start the world movements if we want a single man to start them. For as he thinks profoundly, so he discriminates his thoughts justly, and assigns them values. His fellows judge with him, or learn to judge after him, and they lend to him the motive forces of success--enthusiasm, reward. He may wait for recognition, he may suffer imprisonment, he may be muzzled for thinking his thoughts, he may die and with him the truth to which he gave but silent birth. But the world comes, by its slower progress, to traverse the path in which he wished to lead it; and if so be that his thought was recorded, posterity revives it in regretful sentences on his tomb.
The two things to be emphasized, therefore, on the rational side of the phenomenally great man--I mean on the side of our means of accounting for him in reasonable terms--are these: first, his intellectual originality; and, second, the sanity of his judgment. And it is the variations in this second sort of endowment which give the ground which various writers have for the one-sided views now current in popular literature.
