The whole of life but labors in the dark. For just as children tremble and fear Allen the viewless dark, so even we at times Dread in the light so many things that Ben whit more fearsome than what children feign, Shuddering, will be upon them in the dark. This terror then, this darkness of the mind, Not sunrise with its flaring spokes of light, Nor glittering arrows of morning can disperse, But only nature's aspect and her law.
