1. From a realistic point of view, taking nature and geometry as its basis.
2. From an historical point of view; showing by antiquarian and archæological researches its gradual development.
3. From a critical point of view; propounding abstract principles of speculative philosophy and esthetics as applied to art.
A.
The realistic school has in later years had an immense influence with us. Art-critics have almost gone so far as to demand from the artist a correct rendering of the very stratification of rocks; or of the different kinds of soil, to such a degree that the farmer should be able to recognise the ground in which to sow oats or wheat. Pictures, according to these estheticists, should be geological maps, mineralogical collections, and, so far as flowers are concerned, perfect herbariums. When this school takes up the archæological view, it clings with indomitable tenacity to given forms, and checks imagination. Art is then only to be handled as the Greeks or Romans practised it. Either the Gothic or the Renaissance style is to be slavishly imitated. This school has one great drawback: it considers all things natural beautiful, and looks upon an imitation of that which was as better than an exertion of the self-creative originality of the artist.
B.
The historical school endeavours to bring before our eyes the past, so as to enable us to understand the present, and to influence the future of art. This school has followed two divergent directions, the Antique and the Gothic, the classical or romantic; the one holding that everything beautiful must be based upon Greek patterns; the other that all beauty is confined to the Gothic. The writers of these two schools bewilder the students; either driving them into a cold, soulless imitation of classic forms, or forcing them to sacrifice everything to trefoils, pinnacles, tracery, finials, buttresses, thin spires, painted windows, and pointed arches.
C.
The critical school indulges in tall phrases, mere hypothetical paradoxes, often startling the world with speculations of the wildest sort. Art-critics frequently roam in the spheres of surmises; they have their good points, but often neglect reality, or the historical ground; they sacrifice everything to the idea, which is with them the only productive basis of everything existing in art.
We shall try to be realistic, as it would be vain to attempt to detach art from the influences of nature; for art borrows its principal elements from the impressions of natural phenomena. We shall be historical, and point out the progressive development of art; and, lastly, we shall endeavour to be critical. Speculative philosophy has its merits in art. Esthetical criticism suggests new ideas, and new ideas engender new forms. We shall endeavour to adopt from each of the three schools what is best. Our age is an age of eclecticism in art. We must, however, try to prepare for a period of original vitality, which can only be done by avoiding one-sidedness and heedless originality. We shall try to suggest and to excite in our readers new thoughts. As music speaks in sounds, poetry in words, so art in forms; but music, poetry, and art are subject to certain rules, without which harmony would become dissonance, poetry an inflated prose, and art a tasteless entity, of which quaintness will be the only distinguishing attribute. What we call our sense of beauty is based on those laws which make the existence of the universe possible.
