In one famous instance during the mid-1950s Mises stormed out of a meeting of the Mont Pelerin Society, concerned that the young organization he helped create was falling under the sway of the Chicago school and corrupting its advocacy for uncompromising laissez-faire . One witness to this event was the rising Chicagoite star Milton Friedman, who years later recalled the story as proof of Mises’s intransigence. Mises’s adherence to principle was a strategic error in Friedman’s view, one that would cost Mises influence and money.
Candide underwent one major revision after its initial publication, in addition to some minor ones. In 1761, a version of Candide was published that included, along with several minor changes, a major addition by Voltaire to the twenty-second chapter, a section that had been thought weak by the Duke of Vallière.  The English title of this edition was Candide, or Optimism, Translated from the German of Dr. Ralph. With the additions found in the Doctor's pocket when he died at Minden, in the Year of Grace 1759.  The last edition of Candide authorised by Voltaire was the one included in Cramer's 1775 compilation, l'éditions encadrées , meaning "supervised editions".
