You need to take your dubiousness up with Michael T Ghiselin LOL
No, I'm taking it up with you. Sadly, there are no retraction or admission of previous errors on your part. Dare you address your prior misconstruals?
I looked up Ghiselin's book, and it seems at first glance to be a philosophical work, not a biology text. The quote by Darwin in question was written down in a pocket notebook. I found a cite for it here:
Paul H. Barrett, Peter J. Gautrey, Sandra Herbert, David Kohn, and Sydney Smith, editors, Charles Darwin's Notebooks, 1836-1844: Geology, Transmutation of Species, Metaphysical Enquiries (Cornell University Press, 1987), p. 539.
