I'm using DNA as an example that physical properties are influential for the possibilities of life, not just abstract functions. Consciousness is, as far as we know, limited to things made through the activities of DNA. I am saying we can't assume that there is no reason for that to be the case. > > >> You've been asserting that it's the case...not just cautioning about > >> possibilities.

It is clear to me that there are different sense making capacities associated with different levels of physical substance and relation. It is not all interchangeable, although there are many functions which can be imitated successfully. There is room for many different ways of doing the same thing and many different things that can be done in the same way. Consciousness overlaps with the body in some ways and it diverges in other ways. They are independent, they overlap, they influence each other, and they are in another sense, inseparable. No amount of steel gears is going to ever add up to a chicken. Only a chicken made of chicken cells is a chicken and has chicken consciousness. > and no concede that maybe a > silicon or mechanical brain could instantiate human-like consciousness and > that's a > reasonable research goal and you were just cautioning against assuming the > outcome? It's a reasonable research goal because of the collateral knowledge that will come out of it, but no, I think in reality this goal will always be a pipe dream of alchemical proportions. Mortality is a fundamental experience of all life. As long as a brain is based on time-reversible, non-mortal mechanisms, it can never feel what any living thing can feel. Not that time irreversibility and mortality are the only criteria - but I suspect that they are part of the minimum requirements involved in stepping up from the molecular to the cellular level of sense making.
