This, however, is only one of the more superficial influences which have helped and fallen in with the working of profounder causes of weakened aspiration and impoverished moral energy, and of the substitution of latitudinarian acquiescence and faltering conviction for the whole-hearted assurance of better times. Of these deeper causes, the most important in the intellectual development of the prevailing forms of thought and sentiment is the growth of the Historic Method. Let us consider very shortly how the abuse of this method, and an unauthorised extension and interpretation of its conclusions, are likely to have had something to do with the enervation of opinion. The Historic Method may be described as the comparison of the forms of an idea, or a usage, or a belief, at any given time, with the earlier forms from which they were evolved, or the later forms into which they were developed, and the establishment, from such a comparison, of an ascending and descending order among the facts. It consists in the explanation of existing parts in the frame of society by connecting them with corresponding parts in some earlier frame; in the identification of present forms in the past, and past forms in the present. Its main process is the detection of corresponding customs, opinions, laws, beliefs, among different communities, and a grouping of them into general classes with reference to some one common feature. It is a certain way of seeking answers to various questions of origin, resting on the same general doctrine of evolution, applied to moral and social forms, as that which is being applied with so much ingenuity to the series of organic matter. The historic conception is a reference of every state of society to a particular stage in the evolution of its general conditions. Ideas of law, of virtue, of religion, of the physical universe, of history, of the social union itself, all march in a harmonious and inter-dependent order.
