The statement he made asserts the truth of Natural selection. And whilst your posts make you think you have refuted it, in fact they assert it.
The principle is a natural occurrence not affected by Arminius’ view about what is or is not “best”.
Nature selects what is ‘best’ not because it is ‘best’. It IS best because it is selected! There is no calculation about value or worth- just simply reproductive success.
I think the confusion lies in his head as he is coming from a teleological theistic perspective that assumes that nature is purposeful.
NS: the process whereby organisms better adapted to their environment tend to survive and produce more offspring. The theory of its action was first fully expounded by Charles Darwin, and it is now regarded as be the main process that brings about evolution.
The adaption is simply measured by reproductive success, and that is what is meant by adaptive.
Nature doe not “know” what is best. Nature does not “know” at all. And the law of Natural Selection is not intensional. What is selected, is simply by definition what remains.
