To celebrate the reopening of the newly renovated David M. Rubenstein Rare Book & Manuscript Library, we have brought together books, manuscripts, photographs, recordings and artifacts that document human aspirations. They include legal documents, religious writings, literature, propaganda, advertising, and the visual arts. Some, like Thoreau’s Walden, seek to guide individual conduct. Others, like the Haitian Declaration of Independence, layout out a roadmap for a nation. Still others, like the Ford’s ad campaign in 1943 provide a mirror for collective yearnings. Together these materials demonstrate the breadth of vision of our collective humanity and its endless capacity to change.
