Human (logical) reasoning revolves around an empty middle. We try to understand reality by modelling reality, although a model can’t fuse with what it models. The end of the modelling instead meets a double contradiction: it is both either of two incompatible alternatives and both of them.
However, since we avoid contradictions like the plague, we do not acknowledge this fundamental contradiction, but instead continue revolving around it. It means that we will never understand reality, but instead infinitely revolve around such an understanding.
