But it is not so easy for mental giants who neither hate nor intend to injure their fellows to realize that nevertheless their fellows hate mental giants and would like to destroy them, not only enviously because the juxtaposition of a superior wounds their vanity, but quite honestly because it frightens them. Fear will drive men to any extreme; and the fear inspired by a superior being is a mystery which cannot be reasoned away. Being immeasurable it is unbearable when there is no presumption or guarantee of its benevolence and moral responsibility; in other words, when it has official status. This is the same trend of thought which Mill (11) follows in his _Essay on Liberty_, noting the originality that characterizes genius and the troubles that result from it, and insisting upon freedom for genius in the interests of the general welfare. It would not be denied by anybody that originality is a valuable element in human affairs. There is always need of persons not only to discover new truths, and point out when what were once truths are true no longer, but also to commence new practices, and set the example of more enlightened conduct, and better taste and sense in human life. . . . It is true that this benefit is not capable of being rendered by everybody alike; there are but few persons in comparison with the whole of mankind, whose experiments, if adopted by others, would be likely to be any improvement on established practice. But these few are the salt of the earth; without them, human life would become a stagnant pool. . . . Persons of genius, it is true, are and are always likely to be, a small minority; but in order to have them, it is necessary to preserve the soil in which they grow. Genius can only breathe freely in an atmosphere of freedom. Persons of genius are, _ex vi termini_, more individual than any other people . . . less capable, consequently, of fitting themselves, without hurtful compression, into any of the small number of moulds which society provides in order to save its members the trouble of forming their own character. If from timidity they consent to be forced into one of these moulds, and to let that part of themselves which cannot expand under the pressure remain unexpanded, society will be little better for their genius. If they are of strong character, and break their fetters, they become a mark for the society which has not succeeded in reducing them to common-place, to point with solemn warning as "wild," "erratic," and the like; much as if one should complain of the Niagara River for not flowing smoothly between its banks like a Dutch canal. Mill says further:
