Empirical data seems to suggest that "timing" is all there is to
information in the neural code, see the Flynculus threads!

Do you observe how that elates "difference" as a first class abstract
concept, not unlike what Lester suggests? (This is not to say I agree
with his arguments, only that difference could be treated more
carefully)

Minsky also argues that much of subjective experience is a direct
consequence of analysis of differences, i.e. if the input is static
subjective experience dissolves, both in reactive and reflective
states. There may be a subtle issue of knowledge and experience here,
but I cannot quite pin it down.

That is well taken, indeed.

I have a problem with such theories when they don't lead to a
mathematical insight. I try to back up my arguments with some small
complexity "fact" / "hypothesis", if you recall how I presented a
mathematical interpretation of the irreducibility of mental processes.
