In a recent lecture on Evolution, delivered in Pittsburg, President McCosh said : "My first position is the certainty of evolution. Evolution is but the coming of one thing out of another. No scientific man under thirty years of age in any country denies it, to my knowledge. To oppose it is to injure young men. I am at the head of a college where to declare against it would perplex my best students. They would ask me which to give up, science or the Bible. There is a general progression in nature. The theory that the world was once a vapor from which the earth evolved is not consistent with the scriptures, for they speak of its being 'void without form.' The natural struggles for existence lead to the survival of the fittest, a most benevolent law, and also in accordance with the Scriptures. Man is so constituted with the faculties that God has given him that he learns by experience. Without order, of what benefit would experience be ? Evolution teaches that the present comes out of the past and goes down to the future. Evolution but shows the agencies by which God's plans are carried out. It is but the evolution of Genesis when each 'brings forth after its kind.' Science tells the same story. But what is the limit of the fixedness of the law ? I believe that the evolution of new species is a question in science, and not of religion. It should be left to scientific men."
