I'll try to be succinct and clearer and shuffle along:
While anti-positivism is fine and dandy, you wouldn't be able to discuss it without the real science that exists that created that fine computer of yours. It doesn't run on philosophical bents. If you are against positivism, I can understand. It may not provide all the answers. But positivism is not science. And when science works, you get to post ant-positivistic posts against science (not positivism) using the very computer that science has provided you.
If one limits themself to evolution then they have a problem, which has gone hilariously unaddressed in this forum when I bring it up, or ridiculed by those with no understanding of science or physics: evolutionary mechanisms are better understood, by a huge scale, than gravitational ones.
I, however, doubt that most that attempt to attack evolution with continuously disproved "scientific" arguments or with positivism believe that we will not, someday, discover that one of the four forces of physics cannot be described scientifically but is instead outside science's bounds.
Interestingly, and totally contradicting myself, if one force were to seem somehow the work of a deity it would be gravity: it seems to come from another world (dimension actually) according to many, leaked into ours, and explaining why gravity is so very weak. . .
Quite simply, anti-positivism is a position, and a philosophical way of thinking, and it may very well be the right one. However, if we are arguing about a singular subject, anti-positivism cannot describe to me, for instance, how speciation does or does not occur-- and science does, and it is right and demonstrably so. Evolution is NOT a philosophical subject matter. To say so is to construct an elaborate ruse to confound rather than to inform.
