Professor Simon Newcomb, one of the most brilliant minds our country has produced, says: "It is perfectly reasonable to suppose that beings, not only animated but endowed with reason, inhabit countless worlds in space." Professor Mitchell of the Cincinnati Observatory, in his work, "Popular Astronomy," says,--"It is most incredible to assert, as so many do, that our planet, so small and insignificant in its proportions when compared with the planets with which it is allied, is the only world in the whole universe filled with sentient, rational, and intelligent beings capable of comprehending the grand mysteries of the physical universe." Camille Flammarion, in referring to the utter insignificance of the earth in the immensity of space, puts forward his view thus: "If advancing with the velocity of light we could traverse from century to century the unlimited number of suns and spheres without ever meeting any limit to the prodigious immensity where God brings forth his worlds, and looking behind, knowing not in what part of the infinite was the little grain of dust called the earth, we would be compelled to unite our voices with that universal nature and exclaim--'Almighty God, how senseless were we to believe that there was nothing beyond the earth and that our abode alone possessed the privilege of reflecting Thy greatness and honor.'" The most distinguished astronomers and scientists of a past time, as well as many of the most famous divines, supported the contention of world life beyond the earth. Among these may be mentioned Kepler and Tycho, Giordano Bruno and Cardinal Cusa, Sir William and Sir John Herschel, Dr. Bentley and Dr. Chalmers, and even Newton himself subscribed in great measure to the belief that the planets and stars are inhabited by intelligent beings.
