According to your creed--according to your Bible--the same Being who made the mind of man, who fashioned every brain, and sowed within those wondrous fields the seeds of every thought and deed, inspired the Bible's every word, and gave it as a guide to all the world. Surely the book should satisfy the brain. And yet, there are millions who do not believe in the inspiration of the Scriptures. Some of the greatest and best have held the claim of inspiration in contempt. No Presbyterian ever stood higher in the realm of thought than Humboldt. He was familiar with Nature from sands to stars, and gave his thoughts, his discoveries and conclusions, "more precious than the tested gold," to all mankind. Yet he not only rejected the religion of your brethren, but denied the existence of their God. Certainly, Charles Darwin was one of the greatest and purest of men,--as free from prejudice as the mariner's compass,--desiring only to find amid the mists and clouds of ignorance the star of truth. No man ever exerted a greater influence on the intellectual world. His discoveries, carried to their legitimate conclusion, destroy the creeds and sacred Scriptures of mankind. In the light of "Natural Selection," "The Survival of the Fittest," and "The Origin of Species," even the Christian religion becomes a gross and cruel superstition. Yet Darwin was an honest, thoughtful, brave and generous man. Compare, I beg of you, these men, Humboldt and Darwin, with the founders of the Presbyterian Church. Read the life of Spinoza, the loving pantheist, and then that of John Calvin, and tell me, candidly, which, in your opinion, was a "monster." Even your brethren do not claim that men are to be eternally punished for having been mistaken as to the truths of geology, astronomy, or mathematics. A man may deny the rotundity and rotation of the earth, laugh at the attraction of gravitation, scout the nebular hypothesis, and hold the multiplication table in abhorrence, and yet join at last the angelic choir. I insist upon the same freedom of thought in all departments of human knowledge. Reason is the supreme and final test. If God has made a revelation to man, it must have been addressed to his reason. There is no other faculty that could even decipher the address. I admit that reason is a small and feeble flame, a flickering torch by stumblers carried in the starless night,--blown and flared by passion's storm,--and yet it is the only light. Extinguish that, and nought remains.
