Excerpt from The Monist, Vol. 18: A Quarterly Magazine Devoted to the Philosophy of Science HE following essay contains an argument which, I believe, has never yet been stated by any one else much less refuted. Once I did publish it in the January number of The M must for 1899; but I was completely mis understood by the Editor, Dr. Paul Carus. My reply to him came late; and was not published. In offering this argument now for publication, I throw down the gauntlet to the whole philosophic world, especially to Prof. Ernst Haeckel of Jena, whose recent famous publication briefly sums up the pronouncements of nineteenth century science on the opposite side.
