Eric, I love your 'project'. Do not despair by my liking it, it does make sense to me even outside of the orthodox physicalistic thinking. I don't copy the long text, everybody got it, only some little parts of it, to which I paste some comments (marked - [JM]:)

([JM]: I know: on this list of physicists one can not escape from the word 'energy'. Could anybody DEFINE its meaning - not identifying what it does or how it compares to other concepts (measurements) or why we have to think of it, just the term, in a classically identified meaning) SNIP > Characteristics of a living organism: > ----------------------------------- > 1. It self-replicates (aka reproduces). [JM]: since the prokaryotes nothing reproduces. Nothing replicates 'self'. Especially since the invention of sexes: two organisms activate a process in which a third one is produced as a result, not matching either of the instigating parents. It is the 'species' that may said to reproduce, even this only superficially meant, because the ever changing environmental circumstances result in variations (mutations?) of the reaction-product. The variant can be applicable to the (changed, new) environment, or not, when it does not proliferate. The first case - as observed after some time (many generations, in science) are called "adaptation and natural selection". The 'bad' product died out and are not even observed. (Concurring ideas in Appendix B). SNIP > 3. It is an autonomous agent (within some environmental constraints.) [JM]: perfect with the parenthesis, viewed WITHIN the set boundaries of our modelled observation. (Similarly expressed further on). SNIP > Thesis ... [JM]: I might have (similar?) ideas - expressed in a less physiclistic mode, which, by some, may sound 'just less precise'. Exactly, since I think in not-so-restricted boundary-enclosed modelling and so the equations of identical values are more fuzzy (influenced by the 'neglected' data outside the circle of the actual observational model). This was also an 'unprecise' statement. I concur with the par (in a sense that 'environment is beyond boundaries): > Definition-weakening 3: ENVIRONMENT-DRIVEN METABOLISM< extended to more than just metabolism. The Appendices require more time to my readings. Appendix A is formulated in a rather 'physicalistic' language.A short remark concerning App. B is included above. So I skip the rest. I thank Eric for a great idea and its excellent exposition. [JM] > SNIP
