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.
