Yes...and thank you!

The approach goes like this.....it has two prongs......rather than asking
mechanistic "how?" questions we ask Aristotealian "why?" questions. second,
we do not look at the material aspects of the system, but at its functional
aspects. We quickly learn that these functional aspects DO NOT neatly
decompose into the material parts and in fact usually DISSAPEAR when such a
fractionation is carried out.

Rosen reformulates schroedinger's "what is life" question as " why are
organisms different from machines, or non-orgamisms?" He then procedes to
look at causal relations and answers the question in a way which gives a
clear categorization of the two entities.

OK........but you will be caused some discomfort...this approach is not
harmoneous with the reductionism we all are used to...

in the organism....there is a function called "metabolism"
for years biochemists and others have worked out the mechanistic details of
these reactions step by step.. to deal with metabolism more holistically we
define a mapping
f:A-->B to represent ALL of it. where does that get us? next we take a
big step.
A and B are sets of real biochemicals...molecules. f , however is a
mapping. It is not "physical" in the sense that it itself has no material
aspects even though it operates on physical things. However, one important
function in an ORGANISM is to repair f continually! Thus we can envision
mappings on mappings and we now are discussing vital life processes far
removed from details about the physical constituents.

I'll stop there...but it goes much further and the results are profound!
