The Besetting Sin Of Able Men Is Impatience Of Contradiction And Of Criticism. Even Those Who Do Their Best To Resist The Temptation, Yield To It Almost Unconsciously And Become The Tools Of Toadies And Flatterers.

And Negatively: In Matters Of The Intellect, Do Not Pretend That Conclusions Are Certain Which Are Not Demonstrated Or Demonstrable.
