The Greeks used the word "epistasin" to express the idea that we express by the word science. Our word means certain knowledge. Theirs was understood to mean "coming to a stand," from "epi," upon, and "staseo," to stand. Science takes account of phenomenon and seeks its law. When you apprehend a phenomenon and discover its law you have accomplished all that the term indicates, even though you fail to comprehend the whys and wherefores of the law. "Certain knowledge," this phrase indicates limitation. All that it demands is that you know that which you profess to know. It therefore follows that the word "science" is equally applicable to the comprehensible and incomprehensible. The word is from "scio," _I know_. As men's knowledge, in the present state, at least, is limited, so science, as presented by man, is also limited; but, as men are progressive beings, science and the sciences may increase, adding more and more of truth. There are, however, shores beyond which science will never carry us, but on the contrary will leave us to settle down, to rest forever in content or discontent, just as we choose. The modern hypothesis of materialistic unbelievers is that there is but one substance in the universe, and that is matter. If this be so, then all knowledge pertains to matter, and when you have reasoned yourself to the last element known, or knowable, in physical analysis, which will be the point of departure as well as your ultimate truth behind which you can not go, then, of course, you are where you must rest satisfied or dissatisfied; you have come to the Rubicon beyond which you will never pass. The mere physicist finds, as a legitimate result of his hypothesis of but one substance, his rest in the ultimate of eternal matter and blind force. The Christian, recognizing spiritual substance also, finds his ultimate or resting place in God, who is the last element in vital and mental analysis, and also the Christian's starting point in his inductive reasonings. We realize that scientific knowledge is profitable, even in the field of matter, but if we refuse to science any domain above matter she will lead us to the dust of the grave, there to forsake us forever amid its gloom and sorrow. Here Colonel Ingersoll's "night birds"--for angels he has no use--move with "rustling of wings." When such men reason themselves back to the germ cells and sperm cells, and stand there upon the last element in the analysis of the human body, they are not able to take another step until they acknowledge the existence of spiritual substance as matters master, which ever was, and is above matter, which takes hold of matter and builds germ cells and sperm cells and inhabits them, as the inherent fore which superintends the building, differentiating the species, and determining the sex.
