closely, for we should not find anything very flattering to ourselves. We should see that this movement of relaxation or expansion is nothing but a prelude to laughter, that the laugher immediately retires within himself, more self-assertive and conceited than ever, and is evidently disposed to look upon another's personality as a marionette of which he pulls the strings. In this presumptuousness we speedily discern a degree of egoism and, behind this latter, something less spontaneous and more bitter, the beginnings of a curious pessimism which becomes the more pronounced as the laugher more closely analyses his laughter.
Here, as elsewhere, nature has utilised evil with a view to good. It is more especially the good that has engaged our attention throughout this work. We have seen that the more society improves, the more plastic is the adaptability it obtains from its members; while the greater the tendency towards increasing stability below, the more does it force to the surface the disturbing elements inseparable from so vast a bulk; and thus laughter performs a useful function by emphasising the form of these significant undulations.
