This view seems at first to reduce the probability that accident will at any time sensibly alter the course of affairs.
But if we take historical action and reaction at their moments of equilibrium, we see that the tide of affairs may sometimes appear to follow the drift of a feather. Consider, for instance, the declaration of the Duke of Wellington that the issue of the battle of Waterloo turned upon the closing of the gates of Hugomont Castle by the hand of one man. Wellington was certainly in a position to know if this was true; and in the light of the tremendous events that depended upon the trifling act, does it not appear that accident for one moment outweighed in consequence any necessity that inhered in the character of the French people or that of the nations arrayed against them at Waterloo? It may be the function of Contingency to correct the overconfidence of the evolutionist.
