In his preface to his work on the "Descent of Man," Mr. Darwin quotes this author as a high authority. We see him elsewhere referred to as one of the first physiologists of Germany. Vogt devotes the concluding lecture of the second volume of his work on Man, to the consideration of Darwinism. He expresses his opinion of it, after high commendation, in the following terms. He says that it cannot be doubted that Darwin's "theory turns the Creator—and his occasional intervention in the revolutions of the earth and in the production of species—without any hesitation out of doors, inasmuch as it does not leave the smallest room for the agency of such a Being. The first living germ being granted, out of it the creation develops itself progressively by natural selection, through all the geological periods of our planets, by the simple law of descent—no new species arises by creation and none perishes by divine annihilation—the natural course of things, the process of evolution of all organisms and of the earth itself, is of itself sufficient for the production of all we see. Thus Man is not a special creation, produced in a different way, and distinct from other animals, endowed with an individual soul and animated by the breath of God; on the contrary, Man is only the highest product of the progressive evolution of animal life springing from the group of apes next below him."[28]After this no one can be surprised to hear him say, that "the pulpits of the orthodox, the confessionals of the priests, the platforms of the interior missions, the presidential chairs of the consistories, resound with protestations against the assaults made by Materialism and Darwinism against the very foundations of society." (p. 286) This he calls "Das Wehgeschrei der Moralisten" (the Wail of the Moralists). The designation Moralists is a felicitous one, as applied to the opponents of Vogt and his associates. It distinguishes them as men who have not lost their moral sense; who refuse to limit their faith to what can be proved by the five senses; who bow to the authority of the law written by the finger of God, on the hearts of men, which neither sophistry nor wickedness can effectually erase. All Vogt thinks it necessary to reply to these Moralists is, "Lasst sie bellen, bis sie ausgebellt haben" (Let them bark till they are tired). "Ende."
