Paperback August 2015:

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.

Professor Stauffer 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…"

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.

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 it 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 six element structure of the Cooper Union speech which helped make Lincoln president. It offers a startling revelation about the Declaration of Independence that connects Lincoln to Thomas Jefferson more closely than previously realized. And it 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 logic emancipates rhetoric. Fact anchored 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. The system can be replicated. Any literate person can harness the structure Lincoln used to improve persuasive skills with iron, fact based, logic.

Abraham Lincoln and the Structure of Reason explains how location-based structure leverages logical persuasion.
