I would like to see some actual evidence. The Lewontin quote for instance indicates only Lewontin's view of how science should operate. Yes, it indicates a strong attachment to methodological materialism but - as has been pointed out in other threads - that is not philopsophical materialism. Nor is there anything in the quoted material that attributes Lewontin's stance on this issue to Darwinism.
So far no evidence has been produced that Darwinism is a philosphical view rather than a scientifc theory.
