It was to no advantage for the scholar to investigate any new fields, for all knowledge which was possible for the mind to discover had already been revealed in the Scriptures. Thus declared the Church. We understand why it was that Copernicus did not permit his book to be published until he was dying. We understand also that when Galileo and Bruno had the courage of their convictions, and gave voice to their beliefs, they were persecuted. Galileo was made to recant a discovery that the youngest of children now takes for granted. Bruno was burnt at the stake. We know that astronomy was at a standstill under Church domination, chemistry was forbidden, and the study of natural philosophy was contradicted; while anthropology, which showed on what mythical foundations the story of the fall of man rests, was squelched. The attitude of the Church on geography was hostile to the truth, as witness the persecutions of those who dared to venture that the earth was round. Botany, mathematics, and geometry, as well as the natural sciences, slumbered. Geology, which proved that the earth was more than 6000 years old, was anathematized; archeologists had the greatest difficulty to expound the truth concerning the antiquity of the human race. In purely civil matters, the clergy opposed fire and marine insurance on the ground that it was a tempting of Providence. Life insurance was regarded as an act of interference with the consequence of God's will. Medicine met the most strenuous of opposition. It is impossible in this short study to analyze the specific forms of retardation which the Church exhibited to all of these branches of learning, whose only endeavor it was to search for the truth, to state the facts, and to alleviate and make more bearable man's sojourn on this earth. However, a few of the many instances of retardation on the part of the Church will be pointed out. CHAPTER VII RELIGION AND MEDICINE _Now, when physiologists study the living brain of an ape, they have no grounds for supposing that they are dealing with a dual structure. The brain is not a tenement inhabited by a spirit or soul. The spirit or soul is but a name for the manifestations of the living brain. The leading neurologists of the world are agreed that the same is true of the human brain. It was only when they abandoned the dual conception--an inheritance from the dark ages of medicine--that they began to understand the disorders of man's mind and how to treat them._ _Modern medicine thus strikes at the very root of Christian doctrine. For, if man is truly mortal, if death ends all, if the human soul is but the manifestation of the living brain, as light and heat are the manifestations of a glowing bar of steel, then there can be no resurrection of the dead. Man has the seeds of immortality in him, but the gift is for the race, not for the individual._ SIR ARTHUR KEITH.
