How so? Were the sun not shining, would there be one single shadow? Yes; there would be just one single shadow; all would be shadow. There would be none of those things we call shadows. True; all would be shade; there would be no shadows. By such a little stair was Cosmo landed at a door of deep question. For now _evil_ took the place of _shadow_ in his _solo_ disputation, and the law and the light and the shadow and the sin went thinking about with each other in his mind; and he saw how the Jews came to attribute evil to the hand of God as well as good, and how St. Paul said that the law gave life to sin--as by the sun is the shadow. He saw too that in the spiritual world we need a live sun strong enough to burn up all the shadows by shining through the things that cast them, and compelling their transparency--and that sun is the God who is light, and in whom is no darkness at all--which truth is the gospel according to St. John. And where there is no longer anything covered or hid, could sin live at all? These and such like thoughts held him long--till the noisy streets of the granite city lay far behind. Swiftly the road flew from under the sixteen flashing shoes of the thorough-breds that bore him along. The light and hope and strength of the new-born day were stirring, mounting, swelling--even in the heart of the sad lover; in every _honest_ heart more or less, whether young or old, feeble or strong, the new summer day stirs, and will stir while the sun has heat enough for men to live on the earth. Surely the live God is not absent from the symbol of his glory! The light and the hope are not there without him! When strength wakes in my heart, shall I be the slave to imagine it comes only as the sap rises in the stem of the reviving plant, or the mercury in the tube of the thermometer? that there is no essential life within my conscious life, no spirit within my spirit? If my origin be not life, I am the poorest of slaves!
