All are represented in it, but not all are equally representative of it. Of the four attitudes suggested above, it is the last which is most characteristic. The first fundamental assumption which is taken over by the sixteenth century is that the ultimate standard of human institutions and activities is religion. The architectonics of the system had been worked out in the Summae of the Schoolmen. In sharp contrast to the modern temper, which takes the destination for granted, and is thrilled by the hum of the engine, medieval religious thought strains every interest and activity, by however arbitrary a compression, into the service of a single idea. The lines of its scheme run up and down, and, since purpose is universal and all-embracing, there is, at least in theory, no room for eccentric bodies which move in their own private orbit. That purpose is set by the divine plan of the universe. “The perfect happiness of man cannot be other than the vision of the divine essence.”12
Hence all activities fall within a single system, because all, though with different degrees of immediateness, are related to a single end, and derive their significance from it. The Church in its wider sense is the Christian Commonwealth, within which that end is to be realized; in its narrower sense it is the hierarchy divinely commissioned for its interpretation; in both it embraces the whole of life, and its authority is final. Though practice is perpetually at variance with theory, there is no absolute division between the inner and personal life, which is “the sphere of religion,” and the practical interests, the external order, the impersonal mechanism, to which, if some modern teachers may be trusted, religion is irrelevant.
There is no absolute division, but there is a division of quality. There are—to use a modern phrase—degrees of reality. The distinctive feature of medieval thought is that contrasts which later were to be presented as irreconcilable antitheses appear in it as differences within a larger unity, and that the world of social organization, originating in physical necessities, passes by insensible gradations into that of the spirit. Man shares with other animals the necessity of maintaining and perpetuating his species; in addition, as a natural creature, he has what is peculiar to himself, an inclination to the life of the intellect and of society—“to know the truth about God and to live in communities.”13 These activities, which form his life according to the law of nature, may be regarded, and sometimes are regarded, as indifferent or hostile to the life of the spirit. But the characteristic thought is different. It is that of a synthesis.
The contrast between nature and grace, between human appetites and interests and religion, is not absolute, but relative. It is a contrast of matter and the spirit informing it, of stages in a process, of preparation and fruition. Grace works on the unregenerate nature of man, not to destroy it, but to transform it. And what is true of the individual is true of society. An attempt is made to give it a new significance by relating it to the purpose of human life as known by revelation. In the words of a famous (or notorious) Bull: “The way of religion is to lead the things which are lower to the things which are higher through the things which are intermediate. According to the law of the universe all things are not reduced to order equally and immediately; but the lowest through the intermediate, the intermediate through the higher.”14 Thus social institutions assume a character which may almost be called sacramental, for they are the outward and imperfect expression of a supreme spiritual reality. Ideally conceived, society is an organism of different grades, and human activities form a hierarchy of functions, which differ in kind and in significance, but each of which is of value on its own plane, provided that it is governed, however remotely, by the end which is common to all. Like the celestial order, of which it is the dim reflection, society is stable, because it
