What is probably the most destructive error in all of cognition is the idea that there is a perfect world which this world is an imperfect reflection of.
From that theory also comes the idea that “natural intelligence” would be a mystical “insight” into that perfect world from which ours is derived.
Consider, also, the modern counterpoint to this: the success of the “computer revolution”, the modern success of information systems, and how they are based first and formost on error checking.
The scope of the conflict of these two ideas is almost too broad to fully grasp, and the conflicting ideas are both central to the pursuit of goal-setting and goal-directed action. That means they are central to the pursuit of any pursuit. They are central to moral judgement, norms, law, and what is based on all those things: politics.
