It is a great folly to wish to be wise alone.
In "Reflections; or Sentences and Moral Maxims" (1665–1678). François de La Rochefoucauld (1613–1680) was a noted French author of maxims and memoirs. The view of human conduct his writings describe has been summed up by the words "everything is reducible to the motive of self-interest", though the term "gently cynical" has also been applied.
