 In 1752, Franklin printed a fine if expensive first edition in Philadelphia, while a lower cost second edition printed in London in 1754 appeared with Johnson's corrections and an introduction by Dr. William Smith, provost of the College of Philadelphia.It has been estimated that about half the students in American Colleges between 1743 and 1776 were taught Johnson's moral philosophy.According to Colonial College Historian, J. David Hoeveler, "In the middle eighteenth century, the collegians who studied" the ideas of the new-model colleges "created new documents of American nationhood".
