Tolerance is an attitude of reasoned patience toward evil. A forbearance that restrains us from showing anger or inflicting punishment. Tolerance applies only to persons…never truth. Tolerance applies to the erring, intolerance to the error. Architects are as intolerant of sand as foundations for skyscrapers as doctors are intolerant of germs in the laboratory. Tolerance does not apply to truth or principles. About these things, we must be intolerant, and for this kind of intolerance, so much needed to rouse us from sentimental gush, I make a plea. Intolerance of this kind is the foundation of all stability.
