The trouble with attempting to apply formal logic systems to
humans is that they are incompatible systems. Cognitively, the
amygdala puts the emotional "push" into the pre-frontal cortex
at a greater speed and "width of the pipe" (physical analogy)
than the pathway going from the pre-frontal cortex back to the
amygdala. Emotions come before logic most of the time. To expect
humans to follow formal logic systems in their life choices is
not logical. Also, certainty is an emotional state codified as
"truth" in logic systems. The systems are from humans, based
upon our limited understanding of the cognitive systems as they
existed at the time of the formulation of the logic systems and
then carried on utilizing their own rules once removed from our
misunderstanding of human cognitive systems. Unless you believe
in a platonic realm where such things as formal logic exist in
an permanent state that we can draw from and never changes. But
that's just silly. == was getting tired of the continual appeal
to formal logic as if it's a system that really matters for
anything except conversational games, at least in how I've seen
it used. ==
