But nothing will be gained unless [they] are also educated as citizens... to know about the ends, the beliefs, the purposes, to... which their craft and skill is to contribute... about the basic issues which... every generation of free men has had to decide... [I]t is the liberal arts... that is our lighthouse in the dark and uncharted waters of the postwar world."
