The deepening of the feeling came rapidly, and took exquisite form in the prophet's assurance that his people should "draw water out of the wells of salvation." But here mysticism was beginning to blend with symbolism, and the later developments of the idea pass over almost wholly into the sphere of reflective analogy. So far as the nature-mystic is concerned, he emphasises the continuity of the feeling, from the earliest ages to the present, that in the phenomena of water gushing from a source we have a manifestation of self-activity, as immanent Idea and concrete will. And convinced of the validity of his contention, he is not surprised, as some may be, at the influence which wells and springs have wielded, and still do wield, over the human soul. CHAPTER XIX BROOKS AND STREAMS There is a striking passage in Tylor's "Primitive Culture" which will admirably serve as an introduction to this chapter and the one which is to follow, on "Rivers and Waterfalls." "In those moments of the civilised man's life when he casts off hard dull science, and returns to childhood's fancy, the world-old book of nature is open to him anew. Then the well-worn thoughts come back fresh to him, of the stream's life that is so like his own; once more he can see the rill leap down the hill-side like a child, to wander playing among the flowers; or can follow it as, grown to a river, it rushes through a mountain gorge, henceforth in sluggish strength to carry heavy burdens across the plain. In all that the water does, the poet's fancy can discern its personality of life. It gives fish to the fisher, and crops to the husbandman; it swells in fury and lays waste the land; it grips the bather with chill and cramp, and holds with inexorable grasp its drowning victim. . . . What ethnography has to teach of that great element of the religion of mankind, the worship of well and lake, brook and river, is simply this--that what is poetry to us was philosophy to early man; that to his mind water acted not by laws of force, but by life and will; that the water-spirits of primeval mythology are as souls which cause the water's rush and rest, its kindness and its cruelty; that lastly man finds, in the beings with such power to work him weal or woe, deities with a wider influence over his life, deities to be feared and loved, to be prayed to and praised and propitiated with sacrificial gifts."
