All, I confess I have not followed the mathematical side of this discussion into the blue underlined stuff. Nor do I claim to understand all of the plain text.
However, I am tempted by the idea of a mathematical formalization of "natural design". Here is the argument: What EVERYBODY --from the most dyed in the wool Natural Theologist to the most flaming Dawkinsian -- agrees on is that there is some property of natural objects which we might roughly call their designedness. Tremendous confusion has been sewn by biologists by confusing that property -- whatever it might be -- with the CAUSES of that property, variously God or Natural selection, or what-have-you. So much of what passes for causal explanation in biology is actually description of the "adaptation relation" or what I call, just to be a trouble-maker, "natural design". It seems to me that you mathematicians could do a great deal for biology by putting your minds to a formalization of "natural design". It would put Darwin's theory -- "natural selection begets natural design" out of the reach of tautology once and for all. What I am looking for here is a mathematical formalization of the relations --hierarchy of relations, I would suppose -- that leads to attributions of "designedness". Assuming that one had put a computer on a British Survey Vessel and sent it round the world for five years looking at the creatures and their surroundings, what is the mathematical description of the relation that would have to be obtained before the computer would come home saying that creatures were designed (and rocks weren't). Then -- and only then -- are we in a position to ask the question, "is natural selection the best explanation for this property. My supposition is that ALL current theories will not survive such an analysis. Indeed, we may need a new metaphor altogether. Many of you will be familiar with the notion of fitness landscape. For intuitive purposes, let me turn the landscape upside down, so its peaks are chasms and its valleys are peaks. Now, drop a ball at random into the upside down landscape. Assuming that the landscape is rigid, the ball will roll around until it finds a local minimum. If you put some jitter in the rolling, it might, depending on the size of the jitter and the roughness of the landscape, find the absolute minimum. But all of this assumes that the ball has no effect on the landscape! If we turn the landscape into a semi-rigid net so that the ball deforms the landscape as it rolls through it, then we have a much better metaphor for the relation between an organism's design and the environment in which it is operating. Some organisms -- weedy species -- cause the environment to rise under their feet, so to speak, so they are constantly driven out of whatever valley they settle in; Other organisms modify the environment in their favor and in effect, dig their way into a pit in the landscape. If the ball representing such organisms has inadequate jitter or the landscape is not sufficiently springy, such an organism can dig its way into a pit and then go extinct. In short we need a dynamical theory. But such a theory will never happen until we have a sufficiently subtle (and verbalizable) mathematical formalization of the momentary relation between organisms and their environments that we are trying to explain.
