Among the writers who defend teleology, we can mention two who, starting from the analogy of human teleological action, have pointed out the idea that teleology itself requires a necessity, conformable to law, in the activity of the forces of nature. One of the two is K. E. von Baer, in his oft-quoted essays on striving towards end; and the other is the Duke of Argyll. At a time when the assault against teleology had just begun, this noble author perceived the whole importance and weight of these attacks, and most energetically defended teleology. The expression of the just-mentioned ideas, {289} among others, forms one of the fundamentals of his work, "The Reign of Law" (London, Strahan & Co., first edition published in 1866, and since then in frequently repeated editions); a work which is well fitted to instruct us, in the most interesting manner, regarding the present state of the related questions as they are treated of in Great Britain. * * * * * {290} CHAPTER II. THE DARWINIAN THEORIES AND POSITIVE CHRISTIANITY. Sec. 1. _The Creation of the World._ Now that we have come to a clear understanding of the position of the Darwinian theories in reference to the basis of all religion and of all living religiousness, to theism in general, it remains to be seen what position those of the theories which are reconcilable with theism take in reference to the positive Christian view of the world. We naturally omit all those objects and parts of Christian dogmatics which have no points of contact, or are very indirectly connected with the Darwinian ideas, or which--as, _e.g._, their position in reference to the idea of God in general--have found their principal illustration in our investigation just finished. We shall nevertheless have now to take into consideration once more, although from another side, some objects which we have discussed in treating of the relation of the Darwinian ideas to theism, on account of the specific part which theism has in Christianity. This is especially the case with those Christian facts which belong to the first article of the Apostolic Creed, and immediately also with the doctrine of the creation of the world. {291} At first sight it seems that the evolution theory and Christianity are in no other place more sharply opposed to each other than in that of the history of creation. Darwinism claims for its theory immense periods of time; and geology seems to furnish them according to its demand. The Holy Scripture, on the other hand, teaches a creation of the world in six days. With the attempt to find the right way to end this conflict, we enter upon that part of the border-land between theology and natural science, which, among all others, is most contested, and which has offered to the most luxuriant fancy the widest field of action and the one most profitably taken advantage of.
