...[Prayer] to some may seem impractical. They feel about it as a man may feel, who, not understanding what astronomy has done for life, goes into an observatory and sees the astronomer studying the stars. That the world needs ploughs and looms and locomotives is as plain as a pike-staff; that the real wants of men are on the earth, not in the heavens, appears so obvious that this hard-headed man of common sense may wonder what use could be made of a star-gazing tube that looks away from the earth and seeks the sky. But the fact is that the star-gazer sets the clock by which we time our simplest tasks; he made the almanac by which we measure our days. We never caught a train, nor figured time on contracts, nor set ourselves to any common duty, that we did not put ourselves under obligation to the astronomer. Men never understood this earth until they looked away from it. It never was truly seen until it was seen in its infinite relationships. Galileo and Kepler and Copernicus did not idly dream in impractical aloofness from the needs of men: they rather fought out in their observatories a conflict for the truth that has remade the world.
