Leonardo da Vinci Quotes

“Vision without execution is hallucination. .. Skill without imagination is barren. Leonardo [da Vinci] knew how to marry observation and imagination, which made him history’s consummate innovator.”
― Walter Isaacson, Leonardo da Vinci

“Above all, Leonardo’s relentless curiosity and experimentation should remind us of the importance of instilling, in both ourselves and our children, not just received knowledge but a willingness to question it—to be imaginative and, like talented misfits and rebels in any era, to think different.”
― Walter Isaacson, Leonardo da Vinci

“If we want to be more like Leonardo, we have to be fearless about changing our minds based on new information.”
― Walter Isaacson, Leonardo da Vinci

“Leonardo had almost no schooling and could barely read Latin or do long division. His genius was of the type we can understand, even take lessons from. It was based on skills we can aspire to improve in ourselves, such as curiosity and intense observation. He had an imagination so excitable that it flirted with the edges of fantasy, which is also something we can try to preserve in ourselves and indulge in our children.”
― Walter Isaacson, Leonardo da Vinci

“But I did learn from Leonardo how a desire to marvel about the world that we encounter each day can make each moment of our lives richer.”
― Walter Isaacson, Leonardo da Vinci

“The tongue of a woodpecker can extend more than three times the length of its bill. When not in use, it retracts into the skull and its cartilage-like structure continues past the jaw to wrap around the bird’s head and then curve down to its nostril. In addition to digging out grubs from a tree, the long tongue protects the woodpecker’s brain. When the bird smashes its beak repeatedly into tree bark, the force exerted on its head is ten times what would kill a human. But its bizarre tongue and supporting structure act as a cushion, shielding the brain from shock.1 There is no reason you actually need to know any of this. It is information that has no real utility for your life, just as it had none for Leonardo. But I thought maybe, after reading this book, that you, like Leonardo, who one day put “Describe the tongue of the woodpecker” on one of his eclectic and oddly inspiring to-do lists, would want to know. Just out of curiosity. Pure curiosity.”
― Walter Isaacson, Leonardo Da Vinci

“men who desire nothing but material riches and are absolutely devoid of the desire for wisdom, which is the sustenance and truly dependable wealth of the mind.”
― Walter Isaacson, Leonardo Da Vinci

“In addition to his instinct for discerning patterns across disciplines, Leonardo honed two other traits that aided his scientific pursuits: an omnivorous curiosity, which bordered on the fanatical, and an acute power of observation, which was eerily intense. Like much with Leonardo, these were interconnected. Any person who puts “Describe the tongue of the woodpecker” on his to-do list is overendowed with the combination of curiosity and acuity. His curiosity, like that of Einstein, often was about phenomena that most people over the age of ten no longer puzzle about: Why is the sky blue? How are clouds formed? Why can our eyes see only in a straight line? What is yawning? Einstein said he marveled about questions others found mundane because he was slow in learning to talk as a child. For Leonardo, this talent may have been connected to growing up with a love of nature while not being overly schooled in received wisdom.”
― Walter Isaacson, Leonardo Da Vinci

“His lack of reverence for authority and his willingness to challenge received wisdom would lead him to craft an empirical approach for understanding nature that foreshadowed the scientific method developed more than a century later by Bacon and Galileo. His method was rooted in experiment, curiosity, and the ability to marvel at phenomena that the rest of us rarely pause to ponder after we’ve outgrown our wonder years.”
― Walter Isaacson, Leonardo da Vinci

“There have been, of course, many other insatiable polymaths, and even the Renaissance produced other Renaissance Men. But none painted the Mona Lisa, much less did so at the same time as producing unsurpassed anatomy drawings based on multiple dissections, coming up with schemes to divert rivers, explaining the reflection of light from the earth to the moon, opening the still-beating heart of a butchered pig to show how ventricles work, designing musical instruments, choreographing pageants, using fossils to dispute the biblical account of the deluge, and then drawing the deluge. Leonardo was a genius, but more: he was the epitome of the universal mind, one who sought to understand all of creation, including how we fit into it.”
― Walter Isaacson, Leonardo Da Vinci

“One mark of a great mind is the willingness to change it. We can see that in Leonardo. As he wrestled with his earth and water studies during the early 1500s, he ran into evidence that caused him to revise his belief in the microcosm-macrocosm analogy. It was Leonardo at his best, and we have the great fortune of being able to watch that evolution as he wrote the Codex Leicester. There he engaged in a dialogue between theories and experience, and when they conflicted he was receptive to trying a new theory. That willingness to surrender preconceptions was key to his creativity.”
― Walter Isaacson, Leonardo da Vinci

“This inability to ground his fantasies in reality has generally been regarded as one of Leonardo’s major failings. Yet in order to be a true visionary, one has to be willing to overreach and to fail some of the time. Innovation requires a reality distortion field. The things he envisioned for the future often came to pass, even if it took a few centuries. Scuba gear, flying machines, and helicopters now exist. Suction pumps now drain swamps. Along the route of the canal that Leonardo drew there is now a major highway.”
― Walter Isaacson, Leonardo da Vinci

“Look longer at the picture. It vibrates with Leonardo’s understanding that no moment is discrete, self-contained, frozen, delineated, just as no boundary in nature is sharply delineated. As with the river that Leonardo described, each moment is part of what just passed and what is about to come. This is one of the essences of Leonardo’s art: from the Adoration of the Magi to Lady with an Ermine to The Last Supper and the Mona Lisa, each moment is not distinct but instead contains connections to a narrative.”
― Walter Isaacson, Leonardo Da Vinci

“While at Windsor Castle looking at the swirling power of the “Deluge drawings” that he made near the end of his life, I asked the curator, Martin Clayton, whether he thought Leonardo had done them as works of art or of science. Even as I spoke, I realized it was a dumb question. “I do not think that Leonardo would have made that distinction,” he replied.”
― Walter Isaacson, Leonardo da Vinci

“So did Einstein, who wrote to another friend, “You and I never cease to stand like curious children before the great mystery into which we were born.”5 We should be careful to never outgrow our wonder years, or to let our children do so.”
― Walter Isaacson, Leonardo da Vinci

“While some may see them as the crazy ones, we see genius. Because the people who are crazy enough to think they can change the world are the ones who do.”3”
― Walter Isaacson, Leonardo da Vinci

“Those who are in love with practice without theoretical knowledge are like the sailor who goes onto a ship without rudder or compass and who never can be certain whither he is going,” he wrote in 1510. “Practice must always be founded on sound theory.”11”
― Walter Isaacson, Leonardo da Vinci

“Be curious, relentlessly curious. “I have no special talents,” Einstein once wrote to a friend. “I am just passionately curious.”4 Leonardo actually did have special talents, as did Einstein, but his distinguishing and most inspiring trait was his intense curiosity. He wanted to know what causes people to yawn, how they walk on ice in Flanders, methods for squaring a circle, what makes the aortic valve close, how light is processed in the eye and what that means for the perspective in a painting. He instructed himself to learn about the placenta of a calf, the jaw of a crocodile, the tongue of a woodpecker, the muscles of a face, the light of the moon, and the edges of shadows. Being relentlessly and randomly curious about everything around us is something that each of us can push ourselves to do, every waking hour, just as he did.”
― Walter Isaacson, Leonardo Da Vinci

“Leonardo became known in Milan not only for his talents but also for his good looks, muscular build, and gentle personal style. “He was a man of outstanding beauty and infinite grace,” Vasari said of him. “He was striking and handsome, and his great presence brought comfort to the most troubled soul.”
― Walter Isaacson, Leonardo da Vinci

“An object will display the greatest difference of light and shade when it is seen in the strongest light. . . . But this should not be much used in painting, because the works would be crude and ungraceful. An object seen in a moderate light displays little difference in its light and shade, and this is the case towards evening or when the day is cloudy; works painted then are tender, and every kind of face becomes graceful. Thus, in everything extremes are to be avoided: Too much light gives crudeness; too little prevents our seeing.”
― Walter Isaacson, Leonardo da Vinci

“Leonardo da Vinci liked to boast that, because he was not formally educated, he had to learn from his own experiences instead”
― Walter Isaacson, Leonardo da Vinci

“The glory of being an artist, he realized, was that reality should inform but not constrain.”
― Walter Isaacson, Leonardo da Vinci

“Kenneth Clark referred to Leonardo’s “inhumanly sharp eye.” It’s a nice phrase, but misleading. Leonardo was human. The acuteness of his observational skill was not some superpower he possessed. Instead, it was a product of his own effort. That’s important, because it means that we can, if we wish, not just marvel at him but try to learn from him by pushing ourselves to look at things more curiously and intensely. In his notebook, he described his method—almost like a trick—for closely observing a scene or object: look carefully and separately at each detail. He compared it to looking at the page of a book, which is meaningless when taken in as a whole and instead needs to be looked at word by word. Deep observation must be done in steps: “If you wish to have a sound knowledge of the forms of objects, begin with the details of them, and do not go on to the second step until you have the first well fixed in memory.”
― Walter Isaacson, Leonardo da Vinci

“Leonardo’s Vitruvian Man embodies a moment when art and science combined to allow mortal minds to probe timeless questions about who we are and how we fit into the grand order of the universe. It also symbolizes an ideal of humanism that celebrates the dignity, value, and rational agency of humans as individuals. Inside the square and the circle we can see the essence of Leonardo da Vinci, and the essence of ourselves, standing naked at the intersection of the earthly and the cosmic.”
― Walter Isaacson, Leonardo da Vinci

“he never finished any of the works he began because, so sublime was his idea of art, he saw faults even in the things that to others seemed miracles.”
― Walter Isaacson, Leonardo da Vinci

“how the ability to make connections across disciplines—arts and sciences, humanities and technology—is a key to innovation, imagination, and genius.”
― Walter Isaacson, Leonardo da Vinci

“Leonardo’s relentless curiosity and experimentation should remind us of the importance of instilling, in both ourselves and our children, not just received knowledge but a willingness to question it—to be imaginative and, like talented misfits and rebels in any era, to think different.”
― Walter Isaacson, Leonardo da Vinci

“He had an imagination so excitable that it flirted with the edges of fantasy, which is also something we can try to preserve in ourselves and indulge in our children.”
― Walter Isaacson, Leonardo da Vinci

“Men of lofty genius sometimes accomplish the most when they work least,”
― Walter Isaacson, Leonardo da Vinci

“That goes a step too far, I think. Leonardo did not invent the scientific method, nor did Aristotle or Alhazen or Galileo or any Bacon. But his uncanny abilities to engage in the dialogue between experience and theory made him a prime example of how acute observations, fanatic curiosity, experimental testing, a willingness to question dogma, and the ability to discern patterns across disciplines can lead to great leaps in human understanding.”
― Walter Isaacson, Leonardo da Vinci
