As the first United States Ambassador to France, he exemplified the emerging American nation . Franklin was foundational in defining the American ethos as a marriage of the practical values of thrift, hard work, education, community spirit, self - governing institutions, and opposition to authoritarianism both political and religious, with the scientific and tolerant values of the Enlightenment . In the words of historian Henry Steele Commager, "In a Franklin could be merged the virtues of Puritanism without its defects, the illumination of the Enlightenment without its heat ."
