Study of the Classics and humanities slowly returned in the fourteenth century, which led to increased study of both Ancient Greek and Latin. In the fifteenth and sixteenth centuries, liberal education focused mostly on the classics. Commoners, however, were not too keen on studying the classics, so they instead took up vernacular languages and literature, and also the sciences. Until at least the twentieth century, both humanist and classicist influences remained in the liberal education, and proponents of a progressive education also embraced the humanist philosophy. Study of the classics continued in the form of the Great Books program. Robert Maynard Hutchins brought this program to the University of Chicago. Upon Hutchins' resignation, the university got rid of the program, but an adapted version still exists at Shimer College.
