a reorganization all along the line. When a change is made which immediately touches only a minor point in the scheme, the consequent derangement of the structure of conventionalities may be inconspicuous; but even in such a case it is safe to say that some derangement of the general scheme, more or less far-reaching, will follow. On the other hand, when an attempted reform involves the suppression or thorough-going remodelling of an institution of first-rate importance in the conventional scheme, it is immediately felt that a serious derangement of the entire scheme would result; it is felt that a readjustment of the structure to the new form taken on by one of its chief elements would be a painful and tedious, if not a doubtful process. In order to realize the difficulty which such a radical change in any one feature of the conventional scheme of life would involve, it is only necessary to suggest the suppression of the monogamic family, or of the agnatic system of consanguinity, or of private property, or of the theistic faith, in any country of the Western civilization; or suppose the suppression of ancestor worship in China, or of the caste system in india, or of slavery in Africa, or the establishment of equality of the sexes in Mohammedan countries. It needs no argument to show that the derangement of the general structure of conventionalities in any of these cases would be very considerable. In order to effect such an innovation a very far-reaching alteration of men's habits of thought would be involved also at other points of the scheme than the one immediately in question. The aversion to any such innovation amounts to a shrinking from an essentially alien scheme of life.
