Well, I don't know what a materialist might think I think
  subjectivity means, but I'll explain what I think it means:

  I believe the subjective is an amalgam of sorts, a mixture of
  innumerable influences from uncountable inputs.

  The properties of the nervous system is the main structure of
  the subjective with the very nice property of hysteresis [the
  'lag' of input, - see properties of Spin Glass for tangible
  example].

  Innumerable hysteresis [hysteresii?] become embedded within the
  structures of the nervous system, primarily the fatty blob
  within our skulls.

  The neural ... *sigh* circuitry [I didn't want to use yet
  another 'computational brain' model.. but it works here] - works
  similar to a NOR circuit [or Parallel] , comparing recent inputs
  from the nervous system with internal feed-forward inputs within
  the nervous system itself. Loops.

  When a partial match to enough of the inputs takes place, that
  which is stored in the hysteresis storage spots "pulls forward
  into" the processing center ALL partial matches at once. In
  short: NAND or serial.

  The processing continues.

  Experience of consciousness is only possible because of the
  ability of the system to observe itself "as if" it is the same
  as an external set of inputs.

  But the close proximity to the circuitry gives an extremely high
  success rate in correlating "old NOR recent old" and *this*
  makes up the "me".

  The subjective.

  Note: I do not believe the subjective CAN be developed without
  some sort of bootstrapping... what they call imprinting I think?
  I have images of baby ducks following a mop around or something.

  Life is social and its identity AND continuation can only be
  formed through socialization, either with others of its own
  kind, or with what is different, but in any case would die
  without a proper environment that is beneficial for its
  development. That environment includes whatever patterning is
  necessary for its continuation as "life".

  So many words. All over the place. Train of thought.

  I believe I'm real. I believe I'm unique. I also believe I'm
  common in most ways. I consider my typing right now to be a
  social activity.

  How or whether this relates to a materialist view of the
  subjective, I don't know. I'm not well versed there.
