41. Now, I must very earnestly warn you, in the beginning of my work with you here, against allowing either of these forms of egotism to interfere with your judgment or practice of art. On the one hand, you must not allow the expression of your own favourite religious feelings by any particular form of art to modify your judgment of its absolute merit; nor allow the art itself to become an illegitimate means of deepening and confirming your convictions, by realising to your eyes what you dimly conceive with the brain; as if the greater clearness of the image were a stronger proof of its truth. On the other hand, you must not allow your scientific habit of trusting nothing but what you have ascertained, to prevent you from appreciating, or at least endeavouring to qualify yourselves to appreciate, the work of the highest faculty of the human mind,—its imagination,—when it is toiling in the presence of things that cannot be dealt with by any other power.
42. These are both vital conditions of your healthy progress. On the one hand, observe that you do not wilfully use the realistic power of art to convince yourselves of historical or theological statements which you cannot otherwise prove; and which you wish to prove:—on the other hand, that you do not check your imagination and conscience while seizing the truths of which they alone are cognizant, because you value too highly the scientific interest which attaches to the investigation of second causes.
For instance, it may be quite possible to show the conditions in water and electricity which necessarily produce the craggy outline, the apparently self-contained silvery light, and the sulphurous blue shadow of a thunder-cloud, and which separate these from the depth of the golden peace in the dawn of a summer morning. Similarly, it may be possible to show the necessities of structure which groove the fangs and depress the brow of the asp, and which distinguish the character of its head from that of the face of a young girl. But it is the function of the rightly-trained imagination to recognise, in these, and such other relative aspects, the unity of teaching which impresses, alike on our senses and our conscience, the eternal difference between good and evil: and the rule, over the clouds of heaven and over the creatures in the earth, of the same Spirit which teaches to our own hearts the bitterness of death, and strength of love.
43. Now, therefore, approaching our subject in this balanced temper, which will neither resolve to see only what it would desire, nor expect to see only what it can explain, we shall find our enquiry into the relation of Art to Religion is distinctly threefold: first, we have to ask how far art may have been literally directed by spiritual powers; secondly, how far, if not inspired, it may have been exalted by them; lastly, how far, in any of its agencies, it has advanced the cause of the creeds it has been used to recommend.
44. First: What ground have we for thinking that art has ever been inspired as a message or revelation? What internal evidence is there in the work of great artists of their having been under the authoritative guidance of supernatural powers?
It is true that the answer to so mysterious a question cannot rest alone upon internal evidence; but it is well that you should know what might, from that evidence alone, be concluded. And the more impartially you examine the phenomena of imagination, the more firmly you will be led to conclude that they are the result of the influence of the common and vital, but not, therefore, less Divine, spirit, of which some portion is given to all living creatures in such manner as may be adapted to their rank in creation; and that everything which men rightly accomplish is indeed done by Divine help, but under a consistent law which is never departed from.
The strength of this spiritual life within us may be increased or lessened by our own conduct; it varies from time to time, as physical strength varies; it is summoned on different occasions by our will, and dejected by our distress, or our sin; but it is always equally human, and equally Divine. We are men, and not mere animals, because a special form of it is with us always; we are nobler and baser men, as it is with us more or less; but it is never given to us in any degree which can make us more than men.
45. Observe:—I give you this general statement doubtfully, and only as that towards which an impartial reasoner will, I think, be inclined by existing data. But I shall be able to show you, without any doubt, in the course of our studies, that the achievements of art which have been usually looked upon as the results of peculiar inspiration have been arrived at only through long courses of wisely directed labour, and under the influence of feelings which are common to all humanity.
But of these feelings and powers which in different degrees are common to humanity, you are to note that there are three principal divisions: first, the instincts of construction or melody, which we share with lower animals, and which are in us as native as the instinct of the bee or nightingale; secondly, the faculty of vision, or of dreaming, whether in sleep or in conscious trance, or by voluntarily exerted fancy; and lastly, the power of rational inference and collection, of both the laws and forms of beauty.
46. Now the faculty of vision, being closely associated with the innermost spiritual nature, is the one which has by most reasoners been held for the peculiar channel of Divine teaching: and it is a fact that great part of purely didactic art has been the record, whether in language, or by linear representation, of actual vision involuntarily received at the moment, though cast on a mental retina blanched by the past course of faithful life. But it is also true that these visions, where most distinctly received, are always—I speak deliberately—always, the sign of some mental limitation or derangement; and that the persons who most clearly recognise their value, exaggeratedly estimate it, choosing what they find to be useful, and calling that "inspired," and disregarding what they perceive to be useless, though presented to the visionary by an equal authority.
