They are but sailing foam-bells Along thought's causal stream, And take their shape and sun-colour From that which sends the dream." No doubt the Jew of Amsterdam in his small room grinding his lenses, living on milk-soup and a few raisins, found his piercing mental vision no more shut in by the city-roof above him than had he slept with Jacob's desert-stone for a pillow; and no doubt there are as rare souls, immersed externally in the very noisiest civilization about us, who yet see serenely over and above it. But, with the mass, this is not so; we cannot see past the little material conditions that press on us. When one bends over an ant-heap on a vast plain, that ant-heap with its little millions of existences toiling there are to the one bending over it but an infinitesimal part of the vast landscape, where a hundred other ant-heaps, broken and new, lie around, and over which the sun shines and about which the mighty mountains rise; but to the ant, down in the ant-heap, it is the universe; he does not even know that his ant-heap was heaped out of the red sand and will return to it to-morrow; he knows nothing of the fallen ant-heaps or of the great human eyes looking down at him; were it possible for him to climb to the top of his ant-heap and raise himself up on his tiny legs, and once to look round, he might know something of what the ant-heap was. Most of us in our human ant-heaps are unable to lift ourselves out of them; we mistake the handful of dust we have accumulated round us, and which we call our cities and civilization, for the universe; and the noise we make in gathering it we think is the sound of eternity. Were it not for two things which we cannot obliterate in our civilization--the wail of the newborn child, and the long straight, quiet figure, knowing nothing and seeing nothing, which the hearse carries away--it might well be that we should sink into a state of ignorance and superstition so profound that we should believe, not merely every day but in our sanest moments, that the will of man was the ruling power of life, his work the end, and we ourselves the universe, and beyond us, nothing!
