Darwin denied design and teleology in nature. He denied final causes and ends, which amounts to denying purpose and intention in creation. He was quite proud of this achievement. This was the point of choosing natural selection as the mechanism of evolution. Darwinians after Darwin also deny teleology in nature. As Kellogg said, Darwinism is a non-teleological causal-mechanical theory of nature. I recall a rather sad moment in George Romanes's Scientific Evidences of Organic Evolution where, after putting forth the evidence, he cries out, 'the theist must now despair', 'where is thy God?'. Darwinians are very explicit about all this, but for whatever reason some people just don't get the message.
Au contraire, my friend. Not that we need some man's approval to accept common sense, but Darwin most certainly struggled with ID up until his death.
From Charles Darwin & Intelligent Design Denis O. Lamoureux St. Joseph's College, University of Alberta (Accepted March 2003 in Journal for Interdisciplinary Studies):
...during the last year of his life in a conversation with the Duke of Argyll who recalls: I said to Dr. Darwin, with reference to some of his own remarkable works on the ‘Fertilization of Orchids’ and upon ‘The Earthworms,’ and various other observations he made of the wonderful contrivances for certain purposes in nature–I said it was impossible to look at these without seeing that they were the effect and the expression of mind. I shall never forget Mr. Darwin’s answer. He looked at me very hard and said, “Well, that often comes over me with overwhelming force; but at other times,’ and he shook his head vaguely, adding, ‘it seems to go away” (F. Darwin 1888, I:316).
