I guess the question is whether the mind can see its own fallacy, its erroneous thinking. This is actually quite hard and could be perhaps represented in the analogy of whether water can know that it is wet or a rock that it is hard (the metaphysical question kept aside, i.e. can inanimate things know anything or not). As such the question is if our mind and its operation of thought can look ourside of itself so to speak. What do you think?
