Don't Be So Certain

"One of the most important things in life is what judge Learned Hand described as 'that ever-gnawing inner doubt as to whether you're right.' If you don't have that, if you think you've got an inside track to absolute truth, you become doctrinaire, humorless and intellectually constipated. The greatest crimes in history have been perpetrated by such religious and political and racial fanatics, from the persecutions of the Inquisition on down to Communist purges and Nazi genocide."-Saul Alinsky
