Notice that I have made no claim about the exact process involved.

It may be a physical cause we don't yet know, but that is not the same as a supernatural cause. The history of science is that the number of things considered unexplainable, and previously magical, is diminishing all the time. > ---------------------------------------------- > You claim the putative non-physical influence is ubiquitous in living cells, > so it would not be unreasonable to expect that it would have been observed, > overturning all of science.

The "hard problem" is still hard. It is still hard but *nothing* would offer a satisfactory explanation. If you say the explanation for consciousness is x someone can still ask, But why should x be associated with consciousness? > ------------------------- > to other parts: "observable" in our poor understanding and explanatory power > of the so far discovered knowledge? > Explained by those incomplete causes we SO FAR think we detected?

Saying "I dunno" is OK. It's the scientific way. Saying "I dunno, so it must be magic" is not OK. -- Stathis Papaioannou -- You received this message because you are subscribed to the Google Groups "Everything List" group.
