7. In pursuing our investigations, even into the bowels of the Earth, and into the blue depths of the sky above us, science has demonstrated in an undeniable manner the errors of the Mosaic Genesis taken in its literal sense, and the material impossibility of things having taken place literally as they are there represented to have done. It has thus given severe shocks to some ancient doctrines. The orthodox faith is disturbed; it believes that its very cornerstone is removed by the adoption of these new ideas. But which is most likely to be right, science marching prudently and progressively over the solid ground of figures and observation, without affirming anything before the proof of it is at hand, or history written at an epoch when means of observation were absolutely lacking? Should we believe the person who affirms that two and two make five, and refuses to verify it, or he who says two and two make four, and proves it?
