Child continues: "Astronomy is without question, the grandest of sciences. It deals with masses, distances, and velocities, which in their immensity belong specially to itself alone, and of which the mere conception transcends the utmost stretch of our finite faculties. In no other branch of science is the limited grasp of our intellect more forcibly brought home to us, yet, though baffled in the effort to rise to the level of its requirements, our strivings are by no means profitless. Is it not truly a precious privilege to be able to trace, imperfect though it may be, the hand of the Almighty Architect in these, His grandest works, and to obtain by this means a broader consciousness of His Omnipotence? "Could each one be privileged to look through Herschel's telescope on a clear night, and visibly behold the wonders of the Heavens, our faith in the realities of astronomy would pass with a sudden bound from theory into practice; planets and stars would become henceforth distinct and solid existences in our minds, our doubts vanish, and our belief settle into conviction. We should behold the mysterious moon of our childhood, mapped into brilliant mountain-peaks, and dark precipices, and softly lighted plains; we should see Jupiter shining like another fair Luna, with attendant satellites moving round him in their well-known paths; or turn with admiration to Saturn encircled by his famous ring, with outlines as distinct as if that glorious creation lay but a few miles distant. Perhaps we may behold the beauteous Venus shining with resplendent circular disk, or curiously passing through her many phases in mimic rivalry of the Moon. Or, leaving these near neighbors far behind, we may penetrate more deeply into space, and mark how the bright flashing stars are reduced to a small, round, unmagnifiable point. Such a privilege would give us a more realizing sense of the power of the great Creator." _THE DISCOVERY OF THE MOTION OF THE EARTH AND HEAVENLY BODIES_.
