curriculum into Yale using Dummer's donated Enlightenment books. Johnson offered what he called "The New Learning", which included the works and ideas of Francis Bacon, John Locke, Isaac Newton, Robert Boyle, Copernicus, and literary works by Shakespeare, John Milton, and Joseph Addison. Enlightenment ideas were introduced to the colonists and diffused through Puritan educational and religious networks especially through Yale College in 1718. Religious tolerance Enlightened Founding Fathers, especially Benjamin Franklin, Thomas Jefferson, James Madison and George Washington, fought for and eventually attained religious freedom for minority denominations. According to the Founding Fathers, the United States should be a country where peoples of all faiths could live in peace and mutual benefit. Madison summed up this ideal in 1792 saying, "Conscience is the most sacred of all property." A switch away from established religion to religious tolerance was one of the distinguishing features of the era from 1775 to 1818. The ratification of the Connecticut Constitution in 1818 has been proposed as a date for the triumph if not the end of the American Enlightenment. That new constitution overturned the 180-year-old "Standing Order" and The Connecticut Charter of 1662, whose provisions dated back to the founding of the state in 1638 and the Fundamental Orders of Connecticut. The new constitution guaranteed freedom of religion and disestablished the Congregational church. Intellectual currents The American Enlightenment on the one hand grew from works of European political thinkers such as Locke, Michel de Montaigne, and Jean Jacques Rousseau, who derived ideas about democracy from admiring accounts of American Indian governmental structures brought back from European travelers to the New World in the 16th century. Concepts of freedom and modern democratic ideals were born in "Native American wigwams” and found permanence in Voltaire's Huron. While between 1714 and 1818, an intellectual change took place that seemed to change the British Colonies of America from a distant backwater into a leader in various fields—moral philosophy, educational reform, religious revival, industrial technology, science, and, most notably, political philosophy, the roots of this change were home grown. America saw a consensus on a "pursuit of happiness" based political structure based in large part on Native sources, however misunderstood. A non-denominational moral philosophy replaced theology in many college curricula. Yale College and the College of William & Mary were reformed. Even Puritan colleges such as the College of New Jersey (now Princeton University) and Harvard University reformed their
