From an old college chum of mine. Can you help?

I’m hoping you and/or friends from PD may be able to help me. My colleagues and I are in the process of putting together a new revision of a book we published several years ago, called Foundations of Freedom. The book is a collection of great speeches, historical documents and other writings that are the essence of America and a tribute to this great nation. We are simply looking for suggestions of other documents or speeches to include in this next revision, so that it may fit the page count required by a few major retailers who wish to carry the book. Would you be willing to ask your readers and contributors on PD to post suggestions as to a speech that inspired them or a historical document they love? Perhaps something they would sit with their family at home one evening and teach their children about. Thanks in advance!
