Why Leonardo was a saboteur, Gutenberg went broke, and Florence was weird – Ada Palmer
Dwarkesh Patel (host), Ada Palmer (guest)
In this episode of Dwarkesh Podcast, featuring Dwarkesh Patel and Ada Palmer, Why Leonardo was a saboteur, Gutenberg went broke, and Florence was weird – Ada Palmer explores renaissance humanism’s messy pipeline to science, power, printing, and progress Palmer argues the Renaissance wasn’t a simple “rediscover classics → get science” story but a long, stepwise process: building libraries, expanding access to texts, learning new ways to use information, and only later applying those habits to nature.
Renaissance humanism’s messy pipeline to science, power, printing, and progress
Palmer argues the Renaissance wasn’t a simple “rediscover classics → get science” story but a long, stepwise process: building libraries, expanding access to texts, learning new ways to use information, and only later applying those habits to nature.
She contrasts idealistic humanist goals (Petrarch’s dream of virtuous Roman-style rulers) with how elites used antiquity as propaganda and legitimacy, especially in socially “weird” Florence where merchants ruled without nobility.
The episode also reframes the printing press as an information revolution with delayed payoffs: Gutenberg and early printers went broke because mass production arrived before distribution networks, which later emerged via Venice’s hub logistics and book fairs.
Finally, Palmer stresses that historical actors rarely get the future they want; they create ecosystems that can “go well” in unexpected ways—an analogy the host connects to modern AI governance and unintended consequences.
Key Takeaways
Italian republics clustered where cities could self-sustain after Rome fell.
Palmer links republican survival to local agricultural capacity and urban wealth: strong cities could maintain security and governance; weaker ones gravitated toward lordly protection and monarchic structures.

Humanism began as a moral technology for training rulers, not a science program.
Petrarch and successors sought to recreate the educational environment of Rome (Plato, Cicero, Livy) to produce leaders who would serve the state over family—yet the first “classically trained” elites often became more effective warmakers.

Classical culture functioned as legitimacy and status-judo for upstarts.
The Medici and other non-noble powers used art, architecture, Greek-learning, and curated “Roman” symbolism to invert diplomatic hierarchies—making nobles feel culturally inferior and inducing alliances.

Machiavelli reframed classics as case studies—an early move toward social science.
After observing virtuous rulers fail and ruthless ones succeed, he rejects ‘virtue by osmosis’ and proposes comparing historical examples to infer what works—an analytic method later echoed in Baconian empiricism.

Florence was structurally ‘weird’: an anti-noble, merchant-oligarchic republic using sortition.
Unlike Venice/Genoa’s noble senates, Florence expelled or forced renunciation of nobility and lottery-selected guild elites to govern, locking officials in a tower for short terms to reduce capture—until the Medici learned to game the system.

The Medici’s rise shows how finance + patronage can capture republican institutions.
As papal bankers they controlled huge cash flows and networks; domestically, employing a large share of citizens meant “random” councils reliably included their clients, enabling de facto control without abolishing republican forms.

The ‘Scientific Revolution’ depended on a new social norm: publish and share.
Palmer calls Leonardo a “saboteur” of progress because he hid discoveries; Bacon’s ideal scientist is the honeybee—collecting from nature, processing it, and producing shared, useful knowledge via academies and publication.

Italy’s lack of an Industrial Revolution reflects incentives, not capability.
Palmer suggests Italy’s agricultural/finance dominance reduced pressure to industrialize; political fragmentation, land value, and preference for luxury artisanal output also mattered—even when proto-industrial methods existed.

Today I'm chatting with Ada Palmer, who is a Renaissance historian, a novelist, a composer based at the University of Chicago. And today we're discussing your book, Inventing the Renaissance. Ada, thanks for coming on the podcast.
Been looking forward.
First question. You've got in this period in the late fifteenth century, early sixteenth century in Italy, all these different republics, Venice, Florence, Genoa, um, and that seems unusual both for the time period and for the place.
Yeah.
What gives?
One of the big reasons that the Italian city republics are clustered in Italy is that when the Roman Empire dissolved in the West, individual cities then needed to self-govern. And this is true all across Europe, right? And those individual cities could no longer get the centralized Roman government to oversee supply routes, keep the roads free of bandits, uh, you could no longer import and export goods at scale, you could no longer rely on central infrastructure. You had to support things yourself. Larger, wealthier towns were able to make this transition because they could support themselves from the local resources and the farms attached to them. So the larger, wealthier towns surrounded by good agricultural land were more successful at converting over to, okay, let's have a senate like the old Roman Senate. Let's have our top families form a council. They will rule. We'll set up a republic. A weaker town that can't support itself as well is much more prone to one wealthy family realizes that they can get goons and take over and declare themselves the monarch of the area. Or worse, this town cannot self-sustain. It doesn't have enough. People there can't get food. They are scared. They're afraid of being robbed by people who are desperate. But outside of town, there is a wealthy villa that belongs to a noble family, and they have bodyguards. "Hey, noble family, if I move next to your villa and work for you, will you protect me with your bodyguards?" So towns emptied out and villages, as in villa and its environs-
Mm.
-developed as a result, and a village was a monarchal structure in this sense, that was the migration of people out of a town into the protection zone of a local lordling, right? And then those villages grew to different scales, some of them cities, some not. So Italy had great agriculture and great agricultural land, so more of Italy's cities were able to sustain themselves as towns and be republics.
I feel like the big take of your book is they were trying to resuscitate Roman virtues. What were the things that-- what were the virtues that the Roman emperors had which allowed this, you know, the safety and good government-
Stability.
-et cetera, to work? And, um, I don't understand the connection between reading Cicero and contemplating the virtues of a great emperor to dot, dot, dot science and technology.
[laughing]
Uh, maybe there isn't one, but d-do you think there is one, and what, what exactly is that connection?
