Why Curiosity Creates Better Thinkers
Whatever exists in the universe, in essence, in appearance, in the imagination, the painter has first in his mind and then in his hand.
- Leonardo Da Vinci
Leonardo never received a formal education. Born out of wedlock to a Florentine notary in 1452, he was barred from university and excluded from studying Latin or Greek. What he got instead was a workshop.
At fourteen, his father secured him an apprenticeship with Andrea del Verrocchio, the leading painter and sculptor in Florence. Verrocchio's studio operated nothing like a modern art school. It was a working shop that took commissions for altarpieces, sculptures, banners, armor, and theatrical sets. The apprentices learned whatever the work demanded: drafting, chemistry, metallurgy, plaster casting, leatherworking, mechanics, woodwork, painting, and sculpting. A single project might require knowledge of pigments, anatomy, perspective, and structural engineering. This system trained the apprentices’ minds to move between disciplines because the commissions required it.
When Leonardo left Florence for Milan in 1482, he wrote a letter to Duke Ludovico Sforza pitching his services. He barely mentioned painting. Instead, he described his ability to design portable bridges, cannons, armored vehicles, and hydraulic systems. Only at the end did he note, almost as an afterthought, that he could also paint.
And it wasn’t just a sense of false modesty: Leonardo's notebooks reveal a mind that treated painting as one thread in a much larger fabric. He dissected cadavers to understand how muscles anchored to bone, then used that knowledge to render figures no one had seen before. He studied the way water curled around obstacles, then applied those observations to canal systems. He watched birds in flight for hours, sketching their wings, trying to understand the mechanics well enough to build a machine that could carry a man into the air.
The modern university wouldn’t know what to do with him.
We’ve organized knowledge into departments, then sub-departments, then research specialties so narrow that colleagues in the same hallway cannot follow each other's work. The incentives are all stacked to narrow our vision, purportedly to better focus on our particular specialization. A graduate student who wanders across fields looks unfocused. A professor who publishes outside their lane risks being taken less seriously within it. But the truth is, nothing exists in a vacuum.
Da Vinci wandered constantly. And the wandering was his method. His anatomical studies fed his paintings. His paintings raised questions only engineering could answer. His engineering sketches circled back to problems of motion and light that belonged to no single discipline at all. His curious mind wove a web of interconnected skills and ideas that fed the brilliance he’s remembered for, and he did it all from a point of genuine wonder and appreciation for the craft.
Specialization has its uses. But the most interesting minds rarely stay in one place for long.
