An astronomer who can devote his life to the sublime study of the heavenly bodies, and not exclaim, with deep humility of spirit, Great and marvelous are thy works, Lord God Almighty! Thou art worthy to receive glory, and honor, and power, for thou hast "created all things, and for thy pleasure they were created," is a madman indeed.
