It is otherwise with the _constructions and the interpretations_ which the scientists place upon the facts of science. For instance, there is an evident similarity of structure in many animals; they are built on a similar plan; their organs have similar or even identical functions. These are simply facts ascertained by observation. Their acceptance does not place any burden on Christian faith. But scientists interpret these facts to mean that there is progressive development in animal and plant life. They have found certain laws (Natural Selection and others) by means of which they require only forces resident in matter to explain the universe. On their hypothesis there is no necessity of miracles nor need we believe in God. Observe, this is the result of speculation, not observation; interpretation of facts, but not a conclusion drawn from facts themselves. It is not science but scientists that are opposed to the Christian religion. This view is supported also by the reflection that the history of speculative thought has ever revealed an anti-Christian intent and purpose, a fatal bias of scientists and philosophers against the teachings of Christianity. The modern anatomist and physiologist may declare that his science precludes the necessity of faith in God and of prayer; that through his research he has become a materialist, an atheist. But even in the Middle Ages, when practically all of anatomy and physiology was yet unexplored, the physicians of that day were as materialistic as those of our own. The medieval saying was: "Tres physici, duo athei," "of every three physicians, two are atheists." The science of the Middle Ages differed very materially from the science of our own day. Is it not clear that the same result cannot be produced by causes so dissimilar? That materialism and atheism which scientists announce as a result, is really the starting point of their speculations. Otherwise, how account for the fact that physicists are, as a rule, gross materialists now as they were forty years ago, although all theories regarding the composition of matter have been radically altered since that day? Evidently, the modern scientist is not on account of his research and speculation induced to proclaim himself as agnostic; quite the reverse, the fact that on _any_ system of physics, zoology, psychology, the conclusions remain the same, proves that these conclusions were in the mind before the facts were investigated. Unbelief is not a product of scientific and philosophic speculation, it is rather their origin and source. There is a settled purpose in relation to which the facts are classified and interpreted. Not all scientists are as honest as Huxley who announces this purpose in the introduction of his _"Science and Hebrew Tradition:"_ "These essays are for the most part intended to contribute to the process of destroying the infallibility of Scripture."
