The Watchmaker: my fav argument

[Angrboda]

Hmm there is no arguments from the heap being made by Quine:

"Quine’s most powerful argument is usually seen to be his claim that there is no way to mark out the distinction between changes within and changes between frameworks in a way that is scientific and does not beg the question" (Godfrey-Smith, 2003, p 118).

Reference: Godfrey-Smith, P. (2003). Theory and reality: An introduction to the philosophy of science. Chicago: Chicago University Press.

My argument was addressed to you, not to Quine, but what you've posted seems to be a classical example of the fallacy of the beard which says that if no specific demarcation can be made, then the two things are the same. I'm not familiar with Quine's writings to know that he is saying this, and you haven't presented any evidence that he has, but it does seem that this is what you are trying to say, which is fallacious as noted.
