In most cases use gives to this politic agreement the peace and permanence of settled habit; the body proves itself so far amenable that it is accepted as a needful if uninspiring companion, and its plain usefulness ends by dulling the edged criticisms of the mind. But wherever there is a permanent incompatibility too profound for compromise, an elemental difference keeping the personality continually distraught, then shyness, in the sense in which I understand it, assumes its inalienable dominion. The flame of rebellion may smoulder unobserved while the sufferer is in his own home, but among strangers it will blaze fiercely, as the mind protests against the misinterpretations of its unworthy partner. This burning shame is not the proof of a foolish conceit, as unsympathetic criticism proclaims it, but the visible misery of a keen spirit thwarted by physical defect. The man who manifests it is angered with himself because through a physical hindrance he has failed to take the place which would otherwise be his. He is proud, it may be, but not fatuous; for shyness as a rule implies a comparative quickness and alertness of intellect: its exceeding sensibility is exclusive of dulness; and it is frequently due to the presence in a reluctant body of a mind endowed with active powers. Inasmuch as diffidence appears where the subtler formalities of life are compulsory, it is clear that it essentially belongs to the class called gentle, for this class alone enforces that exacting code of etiquette to which our discomfiture is so largely due. Shyness has seldom place in the patriarchal life where men live, "sound, without care, every man under his own vine or his own fig-tree," nor among those who, perforce pursuing a too laborious existence, have no leisure for superficial refinements. Though here and there you may find a Joseph Poorgrass, it is rare among the simple; it is not a popular weakness, and therefore wins no popular sympathy. Such is its first social limitation: it is almost restricted to the classes which are outwardly refined.
