The Math Book That Made Abraham Lincoln a Genius

Lincoln had almost no formal education. Yet, he memorized 173 geometric propositions from Euclid's Elements. He committed Euclid to memory on horseback, by candlelight and tested himself with a pencil and paper. Not to pass an exam, mind you. To learn what it means to truly demonstrate something. Not just to validate propositions in a court of law. But to establish the principle of equality. That practice transformed how he argued, how he reasoned, and how he wrote the Gettysburg Address. And in this video, I break down exactly what Lincoln memorized, how he studied it, and show you how I used the Magnetic Memory Method to memorize Euclid myself. 🎓 Get "The System" FREE and discover How to Take Back Your Education by Restoring the Missing Liberal Arts That Shaped History's Greatest Minds: 👉 https://www.magneticmemorymethod.com/ts 📺 Watch next — Thomas Jefferson's Secret to Learning Anything Deeply: https://www.youtube.com/watch?v=zrmsVLJr-zc ⏱️ TIMESTAMPS: 0:00 The memory method Lincoln used to become a genius 0:22 I tried Lincoln's method myself 0:33 How Lincoln memorized Euclid in sequence 0:54 173 propositions memorized in order 1:01 Why Lincoln didn't want to be a mathematician 1:33 The principle that applies to ANY subject you're learning 1:49 Why structured chains beat isolated facts 2:32 The biggest mistake soo many students make 3:17 How to give everything you learn a scaffold 3:41 What Euclid's Elements actually is 4:14 How I'm using this same structure to memorize anatomy 4:47 Lincoln's study habits (the second principle) 5:13 The farm implement test that reveals how Lincoln thought 5:56 The Benjamin Franklin connection 6:28 Subscribe for the upcoming Nikola Tesla episode 6:47 Lincoln carried Euclid on horseback (and why it matters) 7:15 An important learning tactic we should all emulate 7:37 Why your body is part of your memory system 8:18 Thomas Jefferson's traveling study table 8:50 "Road work" and why studying in multiple locations works 9:14 Write the chains of reasoning by hand 9:52 Advice for medical board and bar exam students 10:19 How I memorized Euclid using a Memory Palace 10:46 "A point is that which has no parts" ... huh?? 11:18 Why I disagree with "never memorize what you don't understand" 11:47 Where Lincoln's practice leads: Gettysburg 12:01 "Moral, physical, mathematical demonstration" 12:52 Lincoln reinvented a 2,000-year-old classical tradition 13:09 The true origin of "Dedicated to the proposition" 13:47 How memorizing Euclid changed my personal sense of conviction 14:46 Lincoln's boldest claim about Euclid 15:26 How propositional thinking separates you from everyone else 15:40 Connect what you memorize to questions that matter to YOU 16:13 How one of Seneca's best learning principles connects to Lincoln 17:11 What Lincoln would think of today's education system 17:53 Imagine having the complete structure for learning 18:19 How to get "The System" to help you restore the 12 Liberal Arts 20:04 Why memory is the foundation underneath all 12 Liberal arts 20:56 One thing you can use starting tonight 21:26 Lincoln's wake-up call for all of us 22:00 Your memory challenge for today 22:25 Thomas Jefferson's Secret to Learning Anything Deeply The books I'm displaying and drawing upon in today's video are: 📘 Oliver Byrne's Elements of Euclid 📘 Lincoln by David Herbert Donald 📘 Senecas's Letters on Ethics translated by Margaret Graver and A.
