On the other hand, facts which are not accessible to everybody, and can be got at only after much difficulty and labor, nearly always admit of new combinations and theories; so that, if sound understanding and judgment are brought to bear upon them—qualities which do not involve very high intellectual power—a man may easily be so fortunate as to light upon some new theory in regard to them which shall be also true. But fame won on such paths does not extend much beyond those who possess a knowledge of the facts in question. To solve problems of this sort requires, no doubt, a great ideal of study and labor, if only to get at the facts; whilst on the path where the greatest and most widespread fame is to be won, the facts may be grasped without any labor at all. But just in proportion as less labor is necessary, more talent or genius is required; and between such qualities and the drudgery of research no comparison is possible, in respect either of their intrinsic value, or of the estimation in which they are held.
