Jacobi, an eminent algebraist, was fond of saying: “Invert, always Invert”

So based on the above and the regular "rationality quotes" feature I figured why not try a thread for quotes that are not rational? Obviously we do not plain stupidity, but I think quotes that appeal on first listen would qualify. As a side benefit of analyzing specific errors this might serve as an inoculation from rhetoric.
I am using "arational" rather than irrational to highlight this distinction.
