"This is the first book to systematically analyze the structure and craft of Lincoln's speech-making." -Harvard University English and History Professor John Stauffer. He goes on to say, Abraham Lincoln and the Structure of Reason is "…one of the most stunningly original works on Abraham Lincoln to appear in years…"
For the first time anywhere, we tell the story of Abraham Lincoln's mastery pure logic: Six elements, each labeled with a single word, and each defined by a single sentence. The system itself was nearly lost in the dustbin of history.
Authors David Hirsch and Dan Van Haften demonstrate that it was Lincoln’s study of plane geometry provided the structure for Abraham Lincoln's great speeches. Although Lincoln’s fascination with geometry is well documented, most historians concluded that Lincolns study of geometry was little more than mental calisthenics. In fact Lincoln embedded the ancient structure of geometric proof into the Gettysburg Address, the Cooper Union speech, the First and Second Inaugurals, his legal practice, and much of his substantive post-1853 communication.
The book reveals the structure of the Cooper Union speech (which helped make Lincoln president), offers a startling revelation about the Declaration of Independence that connects Lincoln to Thomas Jefferson more closely than previously realized, and shows how the structure of the legal system itself played an important role in Lincoln’s greatness.
Modern science can be traced back to Greek geometric method. But rhetoric, which morphed into speech and then into communications, barely advanced since Aristotle. Lincoln’s location-based, persuasive structural system emancipates speech from Aristotle; logical persuasion is unleashed. For over 150 years, Lincoln's use of geometric method in rhetoric and writing was a secret hiding in plain sight. Virtually any literate person can harness structure to enable Lincoln's iron logic:
Abraham Lincoln and the Structure of Reason explains how location-based structure leverages logical persuasion.
