Such as:
OK, so by necessary primitive, you mean the syntactic or microscopic layer. But take this away, and you no longer have emergence. See endless discussions on emergence - my paper, or Jochen Fromm's book for instance. Does this mean "magical emergence" is oxymoronic? > > You can't use an object derived using the contents of > consciousness(observation) to explain why there are any contents of > consciousness(observation) at all.

How can you construct (eg an animal) without having a complete discription of that animal. So how can an animal self-reproduce without having a complete description of itself. But this then leads to an infinite regress. The solution to this conundrum was found in the early 20th century - first with such theoretical constructs as combinators and lambda calculus, then later the actual genetic machinery of life. If it is possible in the case of self-reproduction, the it will also likely to be possible in the case of self-awareness and consciousness. Stating this to illogical doesn't help. That's what people from the time of Descartes thought about self-reproduction. > COLIN > <snip> > > So this means that in a computer abstraction. > >> d(KNOWLEDGE(t)) > >> --------------- is already part of KNOWLEDGE(t) > >> dt > > RUSSEL > > No its not. dK/dt is generated by the interaction of the rules with the > environment. > > No. No. No. There is the old assumption thing again. > > How, exactly, are you assuming that the agent 'interacts' with the > environment?

Just that chemical potential is not an EM field. The confusion may arise because your head is full of ionic chemistry (for which chemical potential is for all intents and purposes identical to the electrical potential between the ions), but there are two other types of chemical bonds - the covalent and the hydrogen bond. Both of these types of bonds occur between neutral molecules, for which the only electric field is the rather weak van der Waals interaction. > RUSSEL > > You're obviously suggesting single neurons have qualia.

I await the announcement of the Nobel prize committee awarding you a prize for this discovery with interest. In the meantime, I'll just go back to my evolutionary agents, and retain my scepticism about your claims.
