Dear Bob,

I am not sure if I have right to reply, but you make a very important remark.

The answer is: computing nature performs much more than existing computers.

What is computable in computing nature is what nature is able to perform 
through its continuous changes.
Dialectical processes are also typical in nature and thus in the framework of 
computing nature, those also are computations.

In short the question is: what kind of computations are those dialectical 
processes?

That is what we want to learn.

All the best,
Gordana

Dear Gordana,

I'm not sure I agree here. For much of what transpires in nature (not  
just in the living realm), the metaphor of the dialectic seems more  
appropriate than the computational. As you are probably aware,  
dialectics are not computable, mainly because their boundary value  
statements are combinatorically intractable (sensu Kauffman).

It is important to note that evolution (which, as Chaisson contends,  
applies as well to the history of the cosmos [and even the symmetrical  
laws of force]) is driven by contingencies, not by laws. Laws are  
necessary and they enable, but they cannot entail.

Regards,
Bob
