different places, and at different times? Even in such a case, the idea of the unity of mankind would only lose its real basis, if at the same time we were permitted to think also anti-teleologically--if we were permitted to suppose that that which came into existence, repeatedly, and in different places, had each time entirely different causes without a common aim and a common plan. If we think teleologically, we see the unity of mankind, also in case of a polygenetic origin, in the unity of the metaphysical and teleological cause which called mankind into existence; and to rational beings, endowed with mind, as men are, the metaphysical bond is certainly stronger than the physical. {341} Precisely the Darwinian ideas of the origin of species through descent would show us in such a case the real bond which unites mankind. For then we should only have to go back from the different points on the stem-lines of the prehistoric generators of these primitive men, at which men originated otherwise than by generation, in order to arrive finally at a common root of all these stem-lines: the members of mankind would even then remain consanguineous among one another, not only in an ideal, but in a real sense. Now that the idea of the unity of mankind was holy and important to St. Paul, is to be inferred in advance from such a universal mind. And when in Acts XVII, 26, he expresses this idea before the Athenians, so proud of their autochthony, with the words that "of one blood all nations of men dwell on all the face of the earth"; or when, in Romans V, and 1 Corinthians XV, he makes use of the idea in order to explain and to glorify the universal power of redemption of Christ by putting Adam and Christ in opposition to one another, as the first and the second Adam, so that he sees sin and death coming forth from Adam, grace and justice and life from Christ and extending over mankind; then we find this idea quite convincing and natural, and adhere firmly to the quintessence of these truths, even if we acknowledge neither in these passages, nor in Genesis I and II, the intention of God to give us a supernatural manifestation of the exterior process of the creation of man. Paul himself gives us a hint not to follow slavishly a literal interpretation, when he says, in Romans V, "as by one man sin entered into the world and death by sin," and calls this man Adam, although he knows that according to the {342} Biblical relation, Eve was the one who was first seduced, and although he expressly points out and makes use of this priority of the sin of Eve in another connection, and for another reason. Finally, we may here also take into consideration the contradictions which have come up by reason of more recent investigations, in reference to the _prehistoric conditions of man_, and which, especially in England, have been designated as the contradiction between the _elevation theory_ and the _depravation theory_.
