Painting, music, architecture, dance were all important, but the heartbeat of Western culture was the turning pages of a book.

America’s roots spring from documents—the Constitution, the Declaration of Independence, and, indirectly, the Bible. The country’s success depended on high levels of literacy, a robust free press, allegiance to the rule of law (found in books), and a common language across a continent. American prosperity and liberty grew out of a culture of reading and writing. We became People of the Book.
