Re: nature -> "human brain" -> "language terms" ==>> knowledge ?
Alex,
The issues concerning urges, desires, inclinations,
motivations, purposes, intentions, etc., are central
to any theory about intelligence, knowledge, thinking
processes, etc. Whether they are conscious or not
is of secondary importance, since unconscious
motivations can be made conscious through analysis
(psycho- or otherwise).
The main point I was trying to make is that I don't
believe that the distinction between objective and
subjective is clear or useful for explaining much,
if anything.
Mathematics is extremely important for science,
engineering, computer systems, philosophy, psychology,
etc. But it's not necessary to add the word "objective"
to justify using math.
In any case, this entire subject is far too complex
to solve in a few email notes, and as John B. said,
all our mailboxes are filling up.
