It seems to me that a belief in the great truths of science are fully as essential to salvation, as the creed of any church. We are taught that a man may be perfectly acceptable to God even if he denies the rotundity of the earth, the Copernican system, the three laws of Kepler, the indestructibility of matter and the attraction of gravitation. And we are also taught that a man may be right upon all these questions, and yet, for failing to believe in the "scheme of salvation," be eternally lost.
