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".  
Like other neo-Stoic authors of the period, Gournay admits that the nature and authenticity of virtue is elusive. But unlike many of her contemporaries, she does not simply dismiss virtue as a mask of the vice of pride. In Vicious Virtue , she argues that the elusiveness of virtue is tied to the hidden motivations behind virtuous acts. While one may observe external actions, one cannot observe the occult motives inspiring the moral agent to act in an apparently virtuous manner. “One cannot remove from humanity all the virtuous actions it practices because of coercion, self-interest, chance, or accident. Even graver are the external virtues which follow on some vicious inclination…To eliminate all such virtuous acts would place the human race closer to the rank of simple animals than I would dare to say.” Much, if not all, of human moral action is motivated by immoral or amoral factors. External virtuous conduct is caused more by personal interest or accident than by conscious virtuous intention. To eliminate all the moral actions inspired by less than virtuous motives is to eliminate practically all deliberative moral action; the only remaining activity is comparable to that manifested by non-rational animals.
