The authors broke "Lincoln"s code" regarding how he wrote his speeches. Unknown to previous Lincoln scholars, he used a regular template and it is replicatable. Anyone can do it. We prove it in our book, explain it line by line, and show you how it is done. Now anyone can speak and argue like Lincoln. For more than 150 years, historians have speculated about what made Abraham Lincoln great. How did Lincoln create his iron logic, his compelling reason, his convincing oratory, and his memorable writing? Some point to Lincoln"s study of grammar, literature, and poetry. Others believe it was the deep national crisis that elevated Lincoln"s oratory. Most agree though that he honed his persuasive technique in his work as an Illinois attorney.Authors Hirsch and Van Haften persuasively argue, for the first time, that it was Lincoln"s in-depth study of geometry that gave our sixteenth president his verbal structure. Although Lincoln"s fascination with geometry is well documented, most historians have concluded that his study of the subject was little more than mental calisthenics. In fact, conclude the authors, 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.Modern science can be traced back to Greek geometric method, but rhetoric, which morphed into speech and then into communications, has barely advanced since Aristotle. Lincoln"s structure emancipates speech from Aristotle and unleashes limitless possibilities. Indeed, his use of geometric method in rhetoric and writing has long been a secret hiding in plain sight. Virtually any literate person can become an Abraham Lincoln by structuring speech with iron logic, as aptly demonstrated by this remarkable new study.Among other things, the authors artfully demonstrate the real importance of the Cooper Union speech (which helped make Lincoln president), offer a startling revelation about the Declaration of Independence that connects Lincoln to Thomas Jefferson more closely than anyone previously realized, and show how the structure of the legal system played an even more important role in Lincoln"s greatness than heretofore realized.With the publication of Abraham Lincoln and the Structure of Reason, Lincoln immediately takes on a new importance that will open an entirely new avenue of scholarly study.About the Authors: David Hirsch is an attorney in Des Moines, Iowa.

Hirsch co-authored the technology column for the American Bar Association Journal for over a decade. The idea for this book came from a column he co-authored for the ABA Journal in 2007.Dan Van Haften lives in Batavia, Illinois. He has BS, with high honor, and MS degrees in mathematics from Michigan State University, and a Ph.D. in electrical engineering from Stevens Institute of Technology. He began his career with ATandT Bell Laboratories in 1970, and retired from Alcatel-Lucent in 2007. His work involved software development and system testing on telecommunication systems. REVIEWS "No one has examined Euclidian logic alongside Lincoln"s rhetorical and written construction as thoroughly as Mssrs. Hirsch and Van Haften, and the results are startling. We continue to shed our shopworn image of Lincoln as a low-gear country lawyer as we learn more about his cases, and now with this study we see a wholly new angle of his brilliance -- which nevertheless must keep us wondering, How did Lincoln do it? Picking apart his Cooper Institute speech for its inner structure, for example, they reveal how deeply Lincoln had imbibed the classical principles of organization, and how it made him the lawyer and politician he was. Hirsch and Van Haften also offer a guidebook not just for attorneys bent on the same self-improvement, but the simple tools for anyone to do as Lincoln did: learn how to learn, and then demonstrate the rightness of your position."- James M. Cornelius, Curator, Lincoln Collection, Abraham Lincoln Presidential Library and Museum"A brilliant study. . . . The authors conclusively demonstrate how the self-taught Lincoln mastered Euclidean Geometry and used Euclid"s elements in his most famous speeches, including the Gettysburg Address and the Cooper Union Address. Understanding geometry helped organize Lincoln"s mind, his writing, and his political skills. To David Hirsch and Dan Van Haften, all students of Abraham Lincoln and our democracy are indebted."- Frank J. Williams, Chair, The Lincoln Forum, and Retired Chief Justice of the Supreme Court of Rhode Island
