Quantum theory suggests that an electron could be simultaneously present in multiple distinct positions. However the human being can only grasp the existence of such an electron at one position at a time which is that the human decides to look at. You look at it in one position and it disappears in the other, and vice versa.
The process of biological thinking is led by the flow of electrons across our neurons, and shall therefore be influenced by the rules of quantum theory. Which leads us to the following: There is nothing wrong about having two polary opposing opinions about exactly the same subject and in exactly the same time; this in fact must be the norm.
You should feel totally comfortable about expressing your great admiration of Professor Noam Chomsky during the starter course at a dinner party and then expressing your indignation towards him before the mains have arrived. This state of ultimate self-contrariety and of total uninhibited cognitive dissonance is completely natural and shall not make your opinions any weaker; in fact it makes them much more interesting. Those who strive for cognitive harmony are torturing themselves as they only show such coherence on the concious level, whilst their unconcious mind is booming with disparity and flooding with inconsonance. And for that, they will deeply suffer. Consistency is indeed the last refuge of the unimaginative.
