18. _Hydrostatics_.--This science teaches us that several cases reported in the Bible of the waters of rivers and seas being separated and erected in perpendicular columns so as to form embankments, are contradicted by all the laws governing fluids, and hence are wholly incredible. The sciences of optics, meteorology, philology, and psychology might also be included in the above list as being ignored and practically set aside by Bible writers. And yet, in the face of all these facts, Dr. Cheever says, "There is a beautiful harmony between the principles of science and the teachings of the Bible throughout the whole book." And this seems to have been the universal conviction of the disciples of the Christian faith before the progress of scientific discovery in modern times laid bare the errors of the Holy Book. Since that juncture in biblical theology culminated, a new theory has been set on foot to dispose of the scientific errors of the Bible. We are told, as an apology for these errors, that "the Bible was designed to teach religion and morality, and not science." This is too true; but a true system of religion must be based on the principles of science. The plea also discloses a scientific ignorance on the part of the objector in not knowing "there is science in every thing." Hence it is impossible to write on any subject without coming in contact with the principles of science, which you must either conform to or violate. Persons destitute of scientific knowledge, as were Bible writers, are liable, in their ignorance, to stumble into scientific errors in writing on any subject.
