Now, from the beginnings of conscious life, man has found himself surrounded and besieged by un-calculable phenomena. Beaten upon by forces he could not estimate or predict or control, he has sought to solve their sphynx-like riddle, to establish some plausible relation between them, to erect a logical scheme of things. Primitive man, as Worringer demonstrates in his "Form Problems of the Gothic," strove to achieve something of certitude and fixity through the crude but definite lines and forms of neolithic art. Classical man brought into play the vigour and subtlety and ingenuity of intellect in its primal and most dynamic form, expressed through static propositions of almost mathematical exactness. The peoples of the East rejected the intellectual-mathematical method and solution and sought a way out through the mysterious operation of the inner sense that manifests itself in the form of emotion. With the revelation of Christianity came also, and of course, enlightenment, which was not definite and closed at some given moment, but progressive and cumulative. At once, speaking philosophically, the intellectual method of the West and the intuitive method of the East came together and fused in a new thing, each element limiting, and at the same time fortifying the other, while the opposed obscurities of the past were irradiated by the revealing and creative spirit of Christ. So came the beginnings of that definitive Christian philosophy which was to proceed from Syria, Anatolia and Constantinople, through Alexandria to St. Augustine, and was to find its fullest expression during the Middle Ages and by means of Duns Scotus, Albertus Magnus, Hugh of St. Victor and St. Thomas Aquinas. It is an interesting fact, though apart from my present consideration, that this philosophical fusion was paralleled in the same places and at the same time, by an aesthetic fusion that brought into existence the first great and consistent art of Christianity. This question is admirably dealt with in Lisle March Phillipps' "Form and Colour." This great Christian philosophy which lay behind all the civilization of the Middle Ages, was positive, comprehensive and new. It demonstrated divine purpose working consciously through all things with a result in perfect coherency; it gave history a new meaning as revealing reality and as a thing forever present and never past, and above all it elucidated the nature of both matter and spirit and made clear their operation through the doctrine of sacramentalism.
