It is a well- known thing that only idiots are not contradictory; they are absolutely consistent.
It needs a little intelligence to be inconsistent, and it needs immense intelligence to be contradictory. Why does it need immense intelligence? -- because unless you can prove your contradictions are complementaries of an organic unity, you don't have the right to make any contradictions. I have never made any contradiction, because I can prove to you each contradiction has its own function in the organic whole where opposites meet and merge and mingle into one unity.
