I don't have time to discuss that broad topic right now, but I agree it is a mistake to exaggerate or overextend the competence of any discipline.
When I argue for evolution on these threads it is purely concerning worldly knowledge in a particular area. I do not think evolution tells us anything about how we should behave.
It might, however, make useful predictions about how people are likely to behave.
Still, I do think that life/non-life is not the same topic as matter/spirit and that both distinction are legitimate.
Plus, the difference between life and non/life is empirically demonstrated without much difficulty at all unless, (e.g. Doctor Stochastic and Zeno) we have to take into consideration the paradox of viewpoints, which is an epistemological difficulty, not, as I image StJacques would say "a scientific one."
