  1. 0:07This man is Leonardo da Vinci and he is
  2. 0:09remembered for many things, including
  3. 0:10being the author of some of the most
  4. 0:12famous works in the world, such as the
  5. 0:14Mona Lisa or The Last Supper. But if
  6. 0:16you don't know Leonardo, the real him,
  7. 0:17if you don't understand him, you may
  8. 0:18not understand his works either and may
  9. 0:20just find them beautiful and that's it.
  10. 0:22In this video I'm going to try to tell
  11. 0:23you the story of this incredible
  12. 0:25character, who is much, much more than
  13. 0:27just a painter. He wasn't just any guy,
  14. 0:29he was a painter, engineer, scientist,
  15. 0:31sculptor, architect and theorist. He
  16. 0:33had knowledge in practically everything
  17. 0:35. Painting, cartography, astronomy,
  18. 0:37anatomy and even paleontology. He
  19. 0:39designed armored tanks, flying machines
  20. 0:41, even something like a self-driving
  21. 0:43car and he didn't paint like everyone
  22. 0:45else. In this video you're going to
  23. 0:46understand him, you're going to
  24. 0:48understand his philosophy of life, how
  25. 0:49he thought, his painting techniques
  26. 0:51that make these works so incredibly
  27. 0:52famous. We're going to study Leonardo's
  28. 0:54reasoning when he created them to
  29. 0:56understand why these works are much
  30. 0:57more than just beautiful. I promise
  31. 0:59that if you stay until the end of this
  32. 1:01video, you will never see Leonardo or
  33. 1:02his works the same way. Leonardo was
  34. 1:04born on the night of April 15, 1452, on
  35. 1:07the outskirts of Florence, Italy, in a
  36. 1:09small, modest town called Vincy.
  37. 1:12Leonardo's parents came from completely
  38. 1:14different worlds. His mother, Caterina,
  39. 1:16was only 14 years old, illiterate,
  40. 1:18uneducated, a peasant, and lived in
  41. 1:20great poverty. His father, Serpiero,
  42. 1:22was 24 years of age. He was from the
  43. 1:25upper middle class with a high level of
  44. 1:26formal education and heir to land,
  45. 1:28property, and a lucrative business.
  46. 1:30This greatly affected Leonardo's future
  47. 1:32, since this difference in worlds
  48. 1:33prevented his parents from getting
  49. 1:35married, making Leonardo worthy of the
  50. 1:37title of bastard. Although at first
  51. 1:39glance, being a bastard sounds like a
  52. 1:40problem. In Leonardo's case, it was a
  53. 1:42fortune. But before understanding why,
  54. 1:44we need to know the reason why his
  55. 1:45parents did not marry, this went much
  56. 1:46further than the fear that people would
  57. 1:48see them in a bad light. The most
  58. 1:49scandalous thing about their union was
  59. 1:51not the age difference at all. This was
  60. 1:53relatively normal. Families sought to
  61. 1:55marry off their daughters as young as
  62. 1:57possible, almost always in their teens.
  63. 1:59This guaranteed two things that society
  64. 2:01at the time considered fundamental for
  65. 2:03women: virginity before marriage and
  66. 2:05the greatest number of biological years
  67. 2:07possible to give birth and secure heirs
  68. 2:09. And for men, especially those from
  69. 2:11the middle class, Walter delayed
  70. 2:12marriage until they had completed their
  71. 2:14education, established their
  72. 2:15professions, and accumulated the
  73. 2:17financial stability necessary to be
  74. 2:18able to maintain a home. The real
  75. 2:20problem with Leonardo's parents 'union
  76. 2:22was that they belonged to completely
  77. 2:24different social worlds. Marriage at
  78. 2:26this time had nothing to do with love
  79. 2:29or romance. It was fundamentally and
  80. 2:31legally a corporate function between
  81. 2:32two families. Marrying an orphan with
  82. 2:35no land, no money, and no family did
  83. 2:37absolutely nothing to the family
  84. 2:39business and, in fact, harmed it. This
  85. 2:42was the reason why Leonardo was
  86. 2:43considered a bastard. This is a term
  87. 2:45that was used back in that period for
  88. 2:47children born out of wedlock. Since his
  89. 2:49parents were unmarried, Leonardo was
  90. 2:51not even entitled to a royal surname.
  91. 2:53Da Vinci was not his lineage, it was
  92. 2:55simply the place where he was born,
  93. 2:56Leonardo, de Vinci. In the Italy where
  94. 2:58Leonardo was born, being an
  95. 3:00illegitimate child meant that the doors
  96. 3:02to high society and formal education
  97. 3:04were locked. He could not inherit a
  98. 3:06prestigious business from his father,
  99. 3:08he could not attend university, and no
  100. 3:09one bothered to teach him classical
  101. 3:11Latin or basic mathematics. But what at
  102. 3:13the time seemed like a curse, as I said
  103. 3:15, was probably in reality the greatest
  104. 3:17blessing in Leonardo's history. Imagine
  105. 3:19for a moment what would have happened
  106. 3:21if Leonardo had been a legitimate son.
  107. 3:22He would have been taught to draw up
  108. 3:24contracts, seal inheritances, and
  109. 3:26memorize texts. He would have been
  110. 3:27swallowed up by the bureaucracy of
  111. 3:29Florence. The world would probably
  112. 3:31never have known the Mona Lisa or the
  113. 3:32designs for the first flying machine.
  114. 3:35Freed from the shackles of traditional
  115. 3:36education, Leonardo was raised on his
  116. 3:38own. And your uncle Francesco, a man
  117. 3:40who loved the countryside, noticed that
  118. 3:41the boy had trouble concentrating on
  119. 3:43normal tasks, that his mind would jump
  120. 3:44from one place to another, but instead
  121. 3:46of punishing him, he took him to the
  122. 3:47fields and vineyards of Tuscany. There
  123. 3:49Leonardo found the only school he would
  124. 3:52ever need: nature. And in that school
  125. 3:54he developed what would be his great
  126. 3:55superpower, the secret weapon that
  127. 3:57would take him to the top of history:
  128. 3:59an almost obsessive capacity for
  129. 4:00observation. Leonardo didn't look at
  130. 4:02the world; he scrutinized it, lying on
  131. 4:04the ground watching lizards move their
  132. 4:06legs. He would spend hours meditating
  133. 4:08on the course of a river just to
  134. 4:10understand why the water formed little
  135. 4:11whirlpools when it hit the rocks. He
  136. 4:13would catch fireflies to try to
  137. 4:15understand where their light came from,
  138. 4:16and he studied with fascination how the
  139. 4:18leaves of plants made their way to the
  140. 4:20sun. He proudly called himself
  141. 4:22homosensale tre, a name without letters
  142. 4:24, because he understood something that
  143. 4:26the intellectuals of his time ignored.
  144. 4:28True wisdom was not simply written
  145. 4:29within the books of those men who are
  146. 4:31now dead. It was alive, breathing, and
  147. 4:33beating all around him. That curious
  148. 4:34boy who ran through the hills chasing
  149. 4:36insects and drawing flowers was
  150. 4:38unknowingly building one of the most
  151. 4:40brilliant minds the world would ever
  152. 4:42know. A mind that asked the simplest
  153. 4:44yet most revolutionary questions in
  154. 4:47existence. Why? How? That boundless
  155. 4:50curiosity that was born in the fields
  156. 4:52of Tuscany soon needed a larger stage.
  157. 4:54When Leonardo was 12 years old, his
  158. 4:56father, impressed by the strange and
  159. 4:58detailed sketches that the young
  160. 4:59Leonardo was constantly drawing,
  161. 5:01decided to take him to Florence, Italy,
  162. 5:03and this is where the legend begins. At
  163. 5:05that time, Florence was no ordinary
  164. 5:07city; it was the absolute epicenter of
  165. 5:09the Renaissance. It was the birthplace
  166. 5:11of this movement. But to understand why
  167. 5:13Florence was so important to
  168. 5:15Leonardo’s development, you have to
  169. 5:16understand what the Renaissance was. It
  170. 5:18is simply a name for the new ideas that
  171. 5:20were emerging in this place. Florence
  172. 5:22was a pressure cooker of intellect, art
  173. 5:24, and power. Humanism was being born in
  174. 5:26those years. But to understand what
  175. 5:28humanism is, you have to know the ideas
  176. 5:30that existed before the Renaissance and
  177. 5:32any of the ideas it proposed. All
  178. 5:34explanations of reality, nature,
  179. 5:35history, and politics began and ended
  180. 5:37with what the Church determined. The
  181. 5:39main objective was not to discover new
  182. 5:41knowledge, but to use human reason to
  183. 5:43try to understand and defend the truths
  184. 5:45already revealed by the Christian faith
  185. 5:47. If a sacred text or an author
  186. 5:48approved by the Church said something,
  187. 5:51that was an absolute truth.
  188. 5:52Intellectual debate consisted of
  189. 5:54commenting on and interpreting those
  190. 5:56existing texts, not experimenting with
  191. 5:57reality or questioning the sources.
  192. 5:59This was their greatest mistake, as
  193. 6:01they tested all their knowledge in a
  194. 6:03church that at that time had them
  195. 6:05completely subjugated. The truth is
  196. 6:07that the church at that time prohibited
  197. 6:09the people from reading the Bible.
  198. 6:10Access to the Holy Scriptures was
  199. 6:12extremely limited and was not a common
  200. 6:14experience for the majority of the
  201. 6:15population. Only the clergy and the
  202. 6:17intellectual elite had access to these
  203. 6:20texts. What these people didn’t see
  204. 6:21is that the truth is not afraid of
  205. 6:23being questioned. It’s okay to have
  206. 6:24questions, to keep investigating, to
  207. 6:25look at more sources, because there is
  208. 6:27only one truth. No matter how many
  209. 6:29times you question anything, if you are
  210. 6:30truly seeking the truth, there is
  211. 6:32nothing you cannot question. In the
  212. 6:34scriptures themselves that these people
  213. 6:36were forbidden to read, it said this,
  214. 6:37the truth will set you free. But of
  215. 6:39course, it didn't suit them to tell the
  216. 6:41people. The problem with these people
  217. 6:43is that they weren’t even guided by
  218. 6:44what the scriptures they were supposed
  219. 6:46to defend said, but by what the dogma
  220. 6:48of the Church of that time said. Faith
  221. 6:49and the Scriptures were never the
  222. 6:51problem, people were. Another idea that
  223. 6:54people had before the Renaissance was
  224. 6:56that human beings were worth very
  225. 6:57little. People were deceived into
  226. 6:59thinking that if you were born a
  227. 7:01peasant, your divine purpose was to
  228. 7:02work the land with resignation. Born a
  229. 7:04noble, your duty was to fight.
  230. 7:05Questioning the social order or
  231. 7:07attempting to ascend was not only a
  232. 7:09lack of politics, but an act of hubris
  233. 7:11against the divine design of the church
  234. 7:13. These ideas were what began to be
  235. 7:14questioned in the Renaissance. One of
  236. 7:16the ideas that emerged was humanism.
  237. 7:18People were finally realizing that we
  238. 7:21are incredibly valuable, capable of
  239. 7:23doing wonders. The only creatures on
  240. 7:25Earth with the unique capacity for
  241. 7:27reasoning to understand complex ideas,
  242. 7:29the capacity for creativity and
  243. 7:30creation. People were just beginning to
  244. 7:32realize that questioning was never a
  245. 7:34bad thing, but quite the opposite,
  246. 7:36because asking the right questions
  247. 7:37leads to the right answers. Humans were
  248. 7:39no longer seen as irredeemably fallen,
  249. 7:42sinful, and insignificant creatures.
  250. 7:44They were now seen as the pinnacle of
  251. 7:46divine creation, endowed with immense
  252. 7:48dignity, beauty, and intrinsic worth.
  253. 7:50Leonardo, unknowingly, was in the right
  254. 7:52place at the right time when he arrived
  255. 7:54in Florence. But these ideas did not
  256. 7:55come out of nowhere. These ideas were
  257. 7:57made possible by the minds that came
  258. 7:59together in that place. There were the
  259. 8:01best artists of all kinds there,
  260. 8:03philosophers, mathematicians,
  261. 8:04geographers, chemists. But in order for
  262. 8:06these people to come together in that
  263. 8:08place, the power that moves everything
  264. 8:10in this world was needed: money.
  265. 8:12Florence became what it was precisely
  266. 8:13because the city was being financed by
  267. 8:15the influence of the all-powerful
  268. 8:17Medici family. The Medici were a very
  269. 8:19powerful banking family, since they
  270. 8:21were in charge of the banking center of
  271. 8:23all of Europe thanks to the Florin, a
  272. 8:25currency so stable that it served as
  273. 8:27the dollar at the time. The Medici were
  274. 8:29not only the bankers of the people and
  275. 8:31the middle and upper classes. Their
  276. 8:33power reached an international level
  277. 8:35when they became the official bankers
  278. 8:37of the Pope. In Florence, they ruled
  279. 8:39from the shadows, buying loyalties,
  280. 8:41controlling elections, and economically
  281. 8:43destroying their rivals. For the Medici
  282. 8:45, art was public relations and
  283. 8:47propaganda. They financed the best
  284. 8:49architects, sculptors, and painters.
  285. 8:51Characters such as Michelangelo,
  286. 8:53Donatello and Leonardo da Vinci himself
  287. 8:55were financed by this family. There, a
  288. 8:57teenage Leonardo arrived in Florence as
  289. 8:59the illegitimate son of a wealthy
  290. 9:01notary and as such did not receive the
  291. 9:03education expected of a future notary,
  292. 9:05but rather a very basic training.
  293. 9:07However, he entered as an apprentice in
  294. 9:09the workshop of Andrea de Birrochilo,
  295. 9:11the most sought-after artist in the
  296. 9:12city at that time. But Birrochio's
  297. 9:14workshop was not just a place where
  298. 9:16paints were mixed, it was a laboratory
  299. 9:18for innovation, teaching chemistry,
  300. 9:20metallurgy, mechanics and carpentry.
  301. 9:22For Leonardo's hyperactive mind, it was
  302. 9:24an endless impact of games. Leonardo
  303. 9:26soaked up the new spirit of his time.
  304. 9:29He understood the respect for harmony
  305. 9:30and proportion, something that can be
  306. 9:32appreciated throughout his career and
  307. 9:34that you will soon understand better.
  308. 9:35From here on, he shows something that
  309. 9:37had stood out for him since he was
  310. 9:38young. He was a great observer, very
  311. 9:40curious and especially sought constant
  312. 9:43experimentation over theory or reading
  313. 9:45the classics. From his position as an
  314. 9:47observer, he longed to understand his
  315. 9:49studies of light, the anatomy of optics
  316. 9:50, and human psychology. He poured all
  317. 9:52of this into his art, which in turn was
  318. 9:54the best tool for learning about the
  319. 9:56world. To understand this better, one
  320. 9:58must fully understand a concept that
  321. 10:00Leonardo applied and applied throughout
  322. 10:01his life. The whole is greater than the
  323. 10:04sum of its parts. This is a phrase from
  324. 10:06the Greek philosopher Aristotle, but it
  325. 10:08perfectly represents Leonardo. He
  326. 10:11understood this. He understood that a
  327. 10:14person was not their leg, their arm, or
  328. 10:15their eye. They were the combination of
  329. 10:17all their parts. Leonardo understood
  330. 10:19reality in a holistic way. For him, a
  331. 10:21painting was not a collection of
  332. 10:23isolated figures and a body was not a
  333. 10:25sack of independent organs, but living
  334. 10:27systems in which each element only
  335. 10:29gained meaning when interacting with
  336. 10:30the others. This vision was
  337. 10:32artistically embodied in his famous
  338. 10:34smoke art technique, where he managed
  339. 10:36to dissolve individual features into a
  340. 10:38single atmosphere, making the overall
  341. 10:40expression of the face infinitely more
  342. 10:43profound and mysterious than the simple
  343. 10:45sum of its features. Leonardo did not
  344. 10:47paint parts; he painted the whole.
  345. 10:49Leonardo only finished fewer than 20
  346. 10:51works in his entire life. Fewer than 20
  347. 10:54works. He was obsessed with capturing
  348. 10:55the whole of the work. Each of his
  349. 10:57paintings has such tiny and special
  350. 10:59details that I am sure many of them
  351. 11:01continue to go unnoticed even today.
  352. 11:04This was what made Leonardo special. He
  353. 11:06did not focus on one part of the work
  354. 11:08and leave the rest as secondary. He
  355. 11:10understood that the work should be seen
  356. 11:12and enjoyed in its entirety. And he
  357. 11:14applied this not only to art, but to
  358. 11:15everything he did in his life, but
  359. 11:17there is still much that we have yet to
  360. 11:18understand. The climax of this stage
  361. 11:20came with a collaborative work called
  362. 11:22The Baptism of Christ. He commissioned
  363. 11:25his apprentice to paint one of the
  364. 11:26angels, specifically the one on the
  365. 11:28left. He had used oil paint, a novel
  366. 11:30technique at the time, to give the skin
  367. 11:32a luminosity and depth of shadow that
  368. 11:34the rest of the painting simply did not
  369. 11:36have. Here you can see that Leonardo
  370. 11:38not only focused on the angel's face,
  371. 11:40but also on his clothes, his hair,
  372. 11:41everything. The naturalness in the
  373. 11:43folds, the dynamic pose, the expression
  374. 11:45on his face, the transition between
  375. 11:46light and shadow. Leonardo was painting
  376. 11:49the angel, not the parts of the angel.
  377. 11:51But Leonardo was not so much interested
  378. 11:53in art. For him, painting was simply a
  379. 11:55tool. It was a visual means of
  380. 11:57documenting how the world worked and,
  381. 11:59pragmatically, a way of making money to
  382. 12:02fund his true obsession: research and
  383. 12:04invention. Art was a job. His mind, on
  384. 12:07the other hand, belonged to engineering
  385. 12:09and science. It is impossible to
  386. 12:10understand Leonardo's work without
  387. 12:11understanding the way he observed the
  388. 12:13world. And it is impossible to
  389. 12:14understand his way of understanding the
  390. 12:16world without capturing his sense of
  391. 12:17life. Leonardo was never someone who
  392. 12:19focused on just one thing. He liked to
  393. 12:21experiment, discover, and understand.
  394. 12:23So he worked in Berrocho's workshop
  395. 12:25until 147 AD, that is, until he turned
  396. 12:2825. Having already gained a certain
  397. 12:30amount of fame and confidence, he set
  398. 12:32up his own workshop. But it was a
  399. 12:34disaster. He received three commissions
  400. 12:36in 5 years and did not finish any of
  401. 12:38them, which would become another of his
  402. 12:40hallmarks throughout his life:
  403. 12:41procrastinating and abandoning projects
  404. 12:43. As a result, he left many works
  405. 12:45unfinished and many of the ones he
  406. 12:46finished he never delivered to those
  407. 12:48who had commissioned them. Since he did
  408. 12:49not leave anything written about it,
  409. 12:51there is still much debate today about
  410. 12:52the reasons why he signed projects and
  411. 12:54then did not finish them. But it seems
  412. 12:56that the most plausible hypothesis is
  413. 12:57his character, his unhealthy
  414. 12:59perfectionism. He never finished his
  415. 13:01works. To him they were never perfect,
  416. 13:03he never finished them, he just left
  417. 13:05them. As I said, Leonardo was a
  418. 13:06perfectionist and it seems that he
  419. 13:08preferred to do nothing rather than do
  420. 13:10something that he could consider
  421. 13:11mediocre. Another example of this is
  422. 13:14his work The Adoration of the Magi. In
  423. 13:16this famous biblical scene, we can see
  424. 13:18with a glance at the unfinished
  425. 13:19painting the disproportionate ambition
  426. 13:21of Leonardo's proposal, a scene with
  427. 13:23thirty different characters in
  428. 13:25different planes and where we see once
  429. 13:27again this characteristic so
  430. 13:29distinctive of Leonardo. He understood
  431. 13:31that a work is seen as something alive,
  432. 13:33a story expressed, so he studied all
  433. 13:35angles of the scene, not only the
  434. 13:37composition of the work, but absolutely
  435. 13:39all aspects of it. The whole is greater
  436. 13:41than the sum of its parts. But in order
  437. 13:43to capture the whole of the work, to be
  438. 13:45able to represent the complexity of
  439. 13:47people's emotions, it was necessary for
  440. 13:49him to go down to the root, from their
  441. 13:51anatomy to their emotions, and from
  442. 13:53there analyze all their details: from a
  443. 13:55smile, which has so much in the
  444. 13:56anatomical structure that produces the
  445. 13:58smile with a mechanical study of
  446. 14:00tendons, muscles and bones, to the
  447. 14:01motivations for producing the same
  448. 14:03smile, which implies not only a
  449. 14:05psychological study of that person, but
  450. 14:07also of the interaction with the rest
  451. 14:09of the characters. The definitive proof
  452. 14:11of this came a few years later. Tired
  453. 14:13of Florence and looking for new
  454. 14:15horizons, Leonardo at the age of 30
  455. 14:17decided to move to Milan, Italy. In
  456. 14:19order to get a job, he wrote a letter
  457. 14:21of introduction to Ludovico Esfuerza,
  458. 14:23the Duke of Milan. This letter is one
  459. 14:25of the most extraordinary and strange
  460. 14:26resumes in history, but to understand
  461. 14:28this letter it is necessary to know
  462. 14:30that at this time Leonardo saw himself
  463. 14:31more as an engineer than as a painter.
  464. 14:33Leonardo loved spending his time
  465. 14:35designing pulleys, levers and machinery
  466. 14:37of all kinds. When he sent this resume
  467. 14:40to the Duke of Milan, instead of
  468. 14:41presenting himself as the artistic
  469. 14:43genius he already was, Leonardo sold
  470. 14:44himself as the ultimate military
  471. 14:46engineer. Over the course of several
  472. 14:48paragraphs, he promised the Duke
  473. 14:50weapons, light and indestructible
  474. 14:51bridges that could be transported to
  475. 14:53the battlefield, methods for emptying
  476. 14:55the moats of enemy castles, elegantly
  477. 14:57designed cannons that fired storms of
  478. 14:59shrapnel, and silent underground
  479. 15:01passageways. He even proposed the
  480. 15:03design of an armored car, equipped with
  481. 15:05cannons and secure against any attack.
  482. 15:07In other words, he was offering him the
  483. 15:09first war tank in history 500 years
  484. 15:11before they were invented. And only at
  485. 15:14the end of this long list of weapons of
  486. 15:16destruction, almost as a whim, did
  487. 15:18Leonardo add a brief line: In times of
  488. 15:20peace, I believe I can give perfect
  489. 15:22satisfaction in architecture and in
  490. 15:24painting and sculpture. I can do as
  491. 15:26much as anyone else. This letter
  492. 15:28conceals the deepest and most painful
  493. 15:30paradox in Leonardo's soul. The man who
  494. 15:33designed these terrifying death
  495. 15:34machines to curry favor with the rulers
  496. 15:37was, deep down, one of the greatest
  497. 15:38pacifists of his time. In the 15th
  498. 15:41century, Italy was in a state of
  499. 15:43perpetual war between cities like
  500. 15:44Florence, Milan, Venice, and the papacy
  501. 15:47. A duke or ruler like Ludovico Esforzo
  502. 15:49, to whom Leonardo wrote this letter,
  503. 15:51had no need for a painter. Painters
  504. 15:53were plentiful and cheap. What they
  505. 15:55desperately needed to survive was their
  506. 15:57military technology priority. Leonardo
  507. 15:59knew perfectly well what product his
  508. 16:01client needed: engineering solutions
  509. 16:03for war. While Europe was bleeding to
  510. 16:05death in constant war and human and
  511. 16:07animal lives varied very little,
  512. 16:09Leonardo was a very empathetic person,
  513. 16:11not only with people, but also with
  514. 16:12animals. He was a strict vegetarian, an
  515. 16:15absolute rarity in his time. He refused
  516. 16:17to wear leather clothes so as not to
  517. 16:19dress up the death of a living being,
  518. 16:21because after years of animal biology
  519. 16:22and studies he had come to a very
  520. 16:24obvious conclusion, but one that not
  521. 16:25everyone sees. Animals felt pain and
  522. 16:28anguish exactly the same as humans. On
  523. 16:30the one hand, his mind needed the money
  524. 16:32and protection of tyrants and war dukes
  525. 16:34in order to continue his research. But
  526. 16:36on the other hand, his heart revered
  527. 16:38life in all its forms. To understand
  528. 16:40Leonardo, one must understand the
  529. 16:41golden rule that governed his brain.
  530. 16:43For him, everything in the universe was
  531. 16:45connected. Let us recall once again the
  532. 16:47phrase that also describes Leonardo.
  533. 16:49The whole is greater than the sum of
  534. 16:51its parts. Today in schools we are
  535. 16:53taught biology on one side, physics on
  536. 16:54the other, and art in a different class
  537. 16:56. For Leonardo, these separations were
  538. 16:58absurd. He saw the world as a single
  539. 17:01gigantic organism where everything
  540. 17:02obeyed the same laws. Today we know
  541. 17:04fractals, geometric objects whose basic
  542. 17:07, fragmented or apparently irregular
  543. 17:09structure is repeated at different
  544. 17:11scales and in different things that may
  545. 17:13initially seem unrelated, things that
  546. 17:15unless you were like Leonardo you would
  547. 17:17not have seen before. Everything is
  548. 17:19connected. Everything in this world
  549. 17:21obeys the same architecture at
  550. 17:22different levels. Leonardo did not know
  551. 17:25the term fractal, but he saw it
  552. 17:27everywhere. What he saw was
  553. 17:28mathematical proof that everything is a
  554. 17:30network. This philosophy of Universal
  555. 17:33Connection crystallized in 1490 in one
  556. 17:35of his most famous sketches, the
  557. 17:37Vitruvian Man. Marcubitrubio Poleón
  558. 17:39was a Roman engineer who worked under
  559. 17:41Julius Caesar, but he went down in
  560. 17:42history for a treatise on architecture,
  561. 17:44the only one that survives from the
  562. 17:46classical era. In this book, Pitrupio,
  563. 17:48inspired by Plato and other ancient
  564. 17:50philosophers, proposed using man as an
  565. 17:52example of harmony in the proportions
  566. 17:54that the rest of the elements have to
  567. 17:56follow. Each element of a temple, for
  568. 17:57example, had to follow a proportion
  569. 17:59given by the human body that served as
  570. 18:01a canon of harmony between its parts.
  571. 18:03Although at first glance it is just a
  572. 18:04drawing of a naked name inside a circle
  573. 18:06and a square, it is actually one of
  574. 18:08Leonardo's most profound philosophical
  575. 18:10statements. The square represents the
  576. 18:12earthly world, matter, the physical,
  577. 18:14the tangible. The circle represents the
  578. 18:16universe, infinity, divinity. By
  579. 18:18fitting the human being perfectly in
  580. 18:20the center of both figures, Leonardo
  581. 18:22was making us understand that man is
  582. 18:24capable of accessing both worlds, the
  583. 18:26earthly and the divine. Thoughts that
  584. 18:28he shared with Plato. Plato believed
  585. 18:29that there are two levels of reality.
  586. 18:31The sensible world, what we see,
  587. 18:33objects, people, physical things, and
  588. 18:35the world of ideas, which has always
  589. 18:37been there, our consciousness that is
  590. 18:39perfect, eternal and immutable. We are
  591. 18:41not only the only creatures on Earth
  592. 18:43with these exact proportions, we are
  593. 18:45also the only ones with the
  594. 18:46intellectual capacity to transcend
  595. 18:48irrationality. Leonardo understood this
  596. 18:51perfectly and this graph is the
  597. 18:53ultimate representation of this. So, to
  598. 18:55understand the mysteries of creation,
  599. 18:56it was first necessary to understand
  600. 18:58the human machine. And to achieve this,
  601. 19:00Leonardo crossed a line that few dared
  602. 19:02to tread. He challenged the most sacred
  603. 19:04taboos of his time. In the Renaissance,
  604. 19:06the human body was considered a sacred
  605. 19:08temple, the divine creation that should
  606. 19:10be treated with veneration, not as an
  607. 19:12object of technical study. Leonardo,
  608. 19:14however, overcame this qualm. He showed
  609. 19:16respect for corpses, but he also set
  610. 19:18out to study them in depth. Over the
  611. 19:20course of his life, he examined more
  612. 19:22than 30 cadavers, from old people to
  613. 19:24young women. And what he found changed
  614. 19:26science without anyone realizing it at
  615. 19:28the time. One of his most moving and
  616. 19:30daring drawings was when he opened the
  617. 19:32belly of a pregnant woman who had
  618. 19:34tragically died and became the first to
  619. 19:36depict a human fetus resting peacefully
  620. 19:38inside its mother's womb. But
  621. 19:40Leonardo's mind did not stop with
  622. 19:42contemplation. He wanted to use this
  623. 19:44knowledge not only in his paintings,
  624. 19:46but in everything. Leonardo spent hours
  625. 19:48gazing at the sky. At a time when
  626. 19:50people believed that birds floated by
  627. 19:52magic or like ships at sea, Leonardo
  628. 19:54understood aerodynamics. He realized
  629. 19:57that flight was not a miracle, it was
  630. 19:58pure physics, the resistance of air
  631. 20:00against the shape of a wing. That
  632. 20:02epiphany unleashed a storm of
  633. 20:03inventions. He drew up plans for
  634. 20:05enormous mechanical rooms powered by
  635. 20:07human arms and legs. He designed the
  636. 20:09first parachute. He even encased a
  637. 20:11spinning rotor made of linen designed
  638. 20:13to compress air and lift himself up. He
  639. 20:15was dreaming of the helicopter more
  640. 20:17than 400 years before the first one was
  641. 20:19invented. All of this knowledge that
  642. 20:21Leonardo collected throughout his life
  643. 20:23needed a place to exist, even if it was
  644. 20:25on paper. Leonardo rarely wrote about
  645. 20:28his feelings, but when he did, he
  646. 20:30revealed a solitary soul deeply
  647. 20:31tormented by the passage of time. He
  648. 20:34felt that time was slipping through his
  649. 20:35fingers. Bored with everything quickly
  650. 20:37and jumping from one obsession to
  651. 20:39another, he left dozens of paintings
  652. 20:40and sculptures unfinished, earning him
  653. 20:42a reputation as an unreliable
  654. 20:43individual. At times, he felt like a
  655. 20:45failure. On one page of his diary, the
  656. 20:48man writes this: While I thought I
  657. 20:50learned to live, I learned to die. And
  658. 20:52on another he noted, "Tell me if I ever
  659. 20:53did anything. Tell me if I ever did
  660. 20:55anything." In 1503 in Florence, a silk
  661. 20:58merchant named Francesco de Giocondo
  662. 21:00commissioned a portrait of his wife
  663. 21:03Lisa Gerardini. That portrait became
  664. 21:05his total obsession. Leonardo never
  665. 21:07gave the painting to Francesco de
  666. 21:09Geocondo. He never collected payment
  667. 21:11for it. Instead, he kept it for himself
  668. 21:13. He packed the Mona Lisa in his trunks
  669. 21:15and traveled with her for the rest of
  670. 21:17his life. This man who had spent his
  671. 21:19entire life trying to decipher the
  672. 21:21universe inevitably began to age.
  673. 21:23Constant wars in Italy, political
  674. 21:25instability, and fierce rebellion
  675. 21:27against a new generation of artists
  676. 21:29such as the young Michelangelo ended up
  677. 21:31exhausting his spirit. He was a man in
  678. 21:33his seventies whose right hand, the one
  679. 21:35that had drawn the designs of the
  680. 21:37machines of the future, had become
  681. 21:38partially paralyzed. After suffering a
  682. 21:40stroke, he felt tired, marginalized in
  683. 21:43his own country and at that time he
  684. 21:45felt that his greatest enemy was
  685. 21:46finally winning the race. But fate had
  686. 21:49one last act in store for him. The
  687. 21:51young King Francis I of France, a
  688. 21:53monarch fascinated by the Renaissance,
  689. 21:55made Leonardo an offer he couldn’t
  690. 21:57refuse. He offered him the title of
  691. 21:59first painter, engineer, and architect
  692. 22:02to the king, a generous pension, and a
  693. 22:04beautiful residence. The Château de
  694. 22:06Côte was connected by an underground
  695. 22:08passageway to the royal castle of the
  696. 22:10two. And what did the king expect in
  697. 22:11return? Nothing, he demanded nothing.
  698. 22:13First, Francis gave Leonardo the
  699. 22:15greatest gift anyone could give a mind
  700. 22:17like his: time and peace. The king
  701. 22:20visited him almost daily for the simple
  702. 22:22and pure pleasure of sitting and
  703. 22:24talking with him, listening to his
  704. 22:25ideas on philosophy, water, the stars,
  705. 22:27and anatomy. For the first time in his
  706. 22:29history, Leonardo was paid not for what
  707. 22:31his hands could make, but for what his
  708. 22:33mind held. It was there in the
  709. 22:35tranquility of the French countryside
  710. 22:37that Leonardo spent the last three
  711. 22:39years of his life sorting through his
  712. 22:41papers, trying to make sense of the
  713. 22:4213,000 pages of notes he had
  714. 22:44accumulated. On May 2, 1519, at the age
  715. 22:47of 67, the engine of his mind stopped
  716. 22:50forever. Leonardo da Vinci was
  717. 22:51undoubtedly the greatest genius of his
  718. 22:53time, but his perfectionism paralyzed
  719. 22:55him. He never considered that his
  720. 22:57research was sufficiently finished to
  721. 22:59be ready for printing and publication.
  722. 23:01That is why he never published his
  723. 23:02journals. When he died, those notebooks
  724. 23:04were scattered. They were sold off
  725. 23:06piecemeal or hidden in private
  726. 23:07libraries. However, Leonardo may not
  727. 23:09have cared. He did not work for future
  728. 23:12glory or wealth. Although kings, popes,
  729. 23:14and dukes offered him mountains of gold
  730. 23:16throughout his life, he usually refused
  731. 23:17the commissions and the idea did not
  732. 23:19ignite a spark of curiosity in him. For
  733. 23:21him, anyone who pursued material wealth
  734. 23:23was a fool, because he lacked the true
  735. 23:26and only treasure of existence, pure
  736. 23:28knowledge. He taught us that genius is
  737. 23:30not a magical gift that fell from the
  738. 23:32sky, but the result of a fierce
  739. 23:34curiosity, of never giving up in awe
  740. 23:36and of refusing to accept the world as
  741. 23:37it is presented to us. If we have the
  742. 23:39patience to observe carefully, the
  743. 23:41entire universe is willing to whisper
  744. 23:43its secrets to us. I hope to see you in
  745. 23:45the next one.
