In June, 1776, he was appointed a member of the Committee of Five that drafted the Declaration of Independence. Although he was temporarily disabled by gout and unable to attend most meetings of the Committee, Franklin made several small changes to the draft sent to him by Thomas Jefferson. In December, 1776, Franklin was dispatched to France as commissioner for the United States and remained in France until 1785. Franklin retained a lifelong commitment to the Puritan virtues and political values with which he had grown up. Through his civic work and publishing, he succeeded in passing these values into the American culture permanently.

Andrew Dickson White (November 7, 1832 – November 4, 1918) was a U.S. diplomat, author, and educator, best known as the co-founder of Cornell University. In 1869 White gave a lecture on "The Battle-Fields of Science", arguing that history showed the negative outcomes resulting from any attempt on the part of religion to interfere with the progress of science. Over the next 30 years he refined his analysis, expanding his case studies to include nearly every field of science over the entire history of Christianity, but also narrowing his target from "religion" through "ecclesiasticism" to "dogmatic theology."
