Opinion rules the world, and a right appreciation of the influences by which opinion is molded is the surest guide to a knowledge of the time. In ignorant and barbarous ages the notions and beliefs of men are crude, and are controlled by a few, for only a few possess knowledge and influence; and even in the age of Pericles and Augustus, the thought of mankind means the thoughts of some dozens of men. A few vigorous minds founded schools of opinion and style, became intellectual dictators, and asserted their authority for centuries. As the art of printing was yet unknown, and books were rare, the teacher was the speaker; orators held sway over the destiny of nations; and the Christian pulpit became the world's university. But the printing-press in giving to thought a permanent form which is placed under the eyes of the whole world has made the passion, the splendor, the majestic phrase of oratory seem unreal as an actor's speech, evanescent as a singer's tones; and hence the pulpit and the rostrum, though they still have influence, can never again exercise the control over opinion which belonged to them when all men had not become readers. What is true of eloquence may be affirmed of all art. In spite of ourselves, even the best of us find it difficult to make art a serious business; and unless taken seriously, it is vain, loses its soul, and falls into the hands of pretenders and sentimentalists. Once painting, sculpture, architecture, and song were the expression of thoughts and moods which irresistibly appealed for utterance; but with us they are a fashion, like cosmetics and laces. Poetry, the highest of arts, has lost its original character of song, and the poet now deals, in an imaginative way, with problems which puzzle metaphysicians and theologians. The causes that have robbed art of so much of its charm and power have necessarily diminished the influence of ceremonial worship, which is the artistic expression of the soul's faith and love, of its hopes and yearnings. We are, indeed, still subdued by the majesty of dimly lighted cathedrals, by solemn music, and the various symbolism of the ritual, but we feel not the deep awe of our fathers whose knees furrowed the pavement stones, and whose burning lips kissed them smooth; and to blame ourselves for this would serve no purpose. To those who find no pleasure in sweet sounds, we pipe in vain, and argument to show that one ought to be moved by what leaves him cold, is meaningless. Emotion is spontaneous, and adorers, like lovers, neither ask nor care for reasons. There is in fact an element of illusion in feeling; passion is non-rational; and when the spirit of the time is intellectual, men are seldom devout, however religious they may be. The scientific habit of mind is not favorable to childlike and unreasoning faith; and the new views of the physical universe which the modern mind is forced to take, bring us face to face with new problems in religion and morals, in
