[here is what's left of a previous post. KPC]
as is explained in AoK, the 'time' 'sense' that you address reduces
=directly= to relative TD E/I-minimization... =everything= is discussed,
concisely, and the necessary refs. cited, in AoK.
old 'finitizations' (AoK, Ap1, Ap4) are neural-activation 'states' in which
TD E/I is inherently relatively-low and relatively-stable, while new
'finitizations' are both relatively unstable, and relatively-high TD E/I
neural-activation 'states'.
'recency' is 'sensed' along a continuum running from relatively-low to
relatively-high TD E/I.
in addition, the way that TD E/I simultaneously determines behavioral
directionalities is thoroughly integrated with 'time' 'sense' in AoK...
relatively-small TD E/I(up) is "attractive", and is the stuff that underpins
'curiosity'. behavioral directionality derives in the stuff of the 'ramp
architecture' discussions that are distributed within AoK.
remember, as is explained in AoK, 'finitization' [TD E/I-minimization]
occurs via either 'moving toward' or 'moving away from'.
'dangerous' environmental conditions, which are innately TD E/I(up,
up)-generating, are, nevertheless, 'finitized' by manifestations of 'moving
away from' behavior.
the only 'difficulty' is that, be-cause the fact that nervous systems
produce behavior only as a by-product of blindly-automated TD
E/I-minimization, =any= environmental circumstance that results in the
experience of TD E/I(up, up), whether or not it is innately TD E/I(up,
up)-generating, will be 'finitized' by 'moving away from'.
a Sorrow-filled ultimate example of such was in the News today (Sat,
24Jul99)... the slaughter of 14 Serbian farmers by ethnic Albanians in
Kosovo.
the farmers were not an objectively-TD E/I(up, up)-generating environmental
circumstance. nevertheless, be-cause the ethnic Albanians did not understand
how nervous systems process information via blind, automated TD
E/I-minimization, they 'moved away from' the Serbian farmers by killing
them.
they did the work of 'The Beast', Abstract Ignorance.
