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.
