ANNOTATION:
Evolution is unstable

You state that "it must be that evolution produces stability". I don't agree. If you look at e.g. predator-prey or parasite-host interaction, evolution may produce a highly unstable sequence of improvements on both sides, which could even lead to the extinction of either side: if the predator evolves some trait that gives it a large advantage over the prey, in the short term this trait might become prevalent in the predator population, but in the longer term it might lead to extinction of the prey, and eventually of the predator itself.

Although one could say that genes strive for immortality by surviving from one generation of the next as many times as possible, short-term success might lead to long-term failure. Predator-prey cycles are notoriously chaotic, and small (evolutionary) changes may have large effects. I am inclined to think that evolution itself produces a chaotic system, in which each mutation holds the potential of a radical disturbance of the complete system.

I therefore think that your statement that "the will to immortality is now not only desirable, but also evolutionarily demanded" is based on shaky grounds. Furthermore, this will to immortality is individual, i.e., we want *ourselves* to be immortal. Evolution, which only operates from generation to generation, does not care for individual immortality, and not even for immortality of genes. As argued above, short-term survival of genetic material may lead to long-term extinction.

I do agree with you on the issue of free choice, but why do you try to find a justification for the will to immortality in evolution, while at the same time stating that "values cannot be derived from facts about nature"?

One remark about "survival of the fittest" being a tautology: fertility and sexual selection also play a role in reproduction, and can be affected by a creature's features. Such features might even be disadvantageous to direct survival, (see e.g. the long tail of a peacock), but they help the genes to survive into the next generation. The phrase is therefore only a tautology if with "survival" one means survival of genes.

REPLY: Evolution is meta-stable

As far as I can see the fact that evolution is unstable does not in any way contradict the statement that evolution must produce stability. In fact, one depends on the other. Here is a quote from my introduction article on system theory and complexity called Back to Basics:

"...Although various emergent phenomena are very different from each other they do have some things in common. A very important concept that connect all emergent phenomena is meta-balance. It is a very strange concept and perhaps *the* key to understanding emergence. A system that is in meta-balance may be viewed from two different perspectives. On the level of detail the system is completely *out*of*balance*. However, from a global perspective the system seems to be stable and ordered. The strange thing is that the system MUST be out of balance in order to produce global order. This is perhaps the most counterintuitive aspect of systems theory...."
