Why the joint stock company was one of the world’s best inventions

A company pools capital for entrepreneurs, and distributes risk for investors.

The oldest forms were extensions of the state, typically time-bound efforts to reach some goal of an empire. Victorian England introduced “limited liability,” in which investors were not liable for anything beyond their investment, and tradable shares.

This invention of invention helped fuel the Industrial Revolution. That’s from the 2003 book The Company: A Short History of a Revolutionary Idea by journalists John Micklethwait and Adrian Wooldridge.

More than 20 years old, the short snappy book was written in the wake of the Enron and Worldcom scandals. Before even the Great Recession, these business journalists were already asking: “Is the company essentially a private association, subject to the laws of the state but with no greater obligation than making money, or a public one which is supposed to act in the public interest?”

That questions remains important today. Even as it’s become far easier to start a company, as the authors write: “The modern company still needs a franchise from society”

How a poem’s 1417 rediscovery shaped the Enlightenment

The concept hooked me: Lucretius’s On the Nature of Things, a materialist Roman poem, gets rediscovered in 1417 by book-hunter Poggio Bracciolini, and its ideas — atoms, a universe without divine design, pleasure as a worthy pursuit — help crack open the modern world.

That’s the setup of The Swerve: How the World Became Modern, a 2011 book by historian Stephen Greenblatt that won both the Pulitzer Prize and National Book Award. I just read it.

What I actually wanted was the origins story: how could anyone in the centuries BCE arrive at “atomism” at all, with no microscopes and no evidence? The book gave me less of that than I hoped, so I went digging on my own — and that turned out to be the more rewarding part. The answer: ancient atomism wasn’t a discovery. It was a logical deduction. Parmenides had argued that nothing can come from nothing and therefore change is impossible; Democritus’s answer was tiny, eternal, uncuttable bits (atomos) rearranging in a void. It only looks like modern science because the word survived. The concept was independently rebuilt on real evidence 2,000 years later.

Which reframed the whole book for me. The Swerve isn’t really a book of ideas — it’s a beautifully written, story-forward narrative built on a single irresistible image: a lone bibliophile pulling a lost masterpiece off a monastery shelf at exactly the right moment to change everything. That’s why it won: gorgeous prose, a great yarn, and a secular-humanist thesis that landed perfectly in the science-vs-religion mood of 2011.

The insight I want to keep: Greenblatt’s book is itself an example of its own thesis. It’s a work that met its moment — the right idea, well-told, arriving when the culture was primed to reward it. Drop it into today and I’m not sure it wins anything. Books, like the texts they’re about, get lucky in their timing.

Below I share my notes from the book for future reference.

The corporation was invented to serve the people

Apple and Amazon are valued by public markets far in excess of their tangible assets, because of their “intangibles” in R&D and brand recognition. By historic standards, they own very little.

In contrast, AerCap and Prologis are among the world’s largest owners of the “means of production.” One leases aircraft to most large airlines. The other is the world’s largest industrial real estate company, leasing warehouses and data centers. They own the stuff.

Both “are nevertheless rather unimportant intermediaries in the modern economy” that now reflect “a long chain of intermediation” that means the system is more distributed. Yet our view and language about how companies fit into our world hasn’t changed.

That’s from The Corporation in the Twenty-First Century: Why (Almost) Everything We Are Told About Business Is Wrong, a 2024 book by knighted economist John Kay.

The old industrial meaning of “capital” meant the owned means of production — mills, railways, steel plants, assembly lines. In many modern firms, Kay argues, those assets are fungible, often rented, and less important than the firm’s collective capabilities.

Among his criticisms is how today’s shareholder priority has distracted from the corporation’s origins as a device of the state. Executives can extract value in the short term, but this narrow-mindedness is provably harmful to corporations in the medium term. Business and economics thought has become far too self interested. Its champions treat “collective action” and “collective knowledge” as accidental overflow rather than our truly natural state. The book is thoughtful and important, given that its from among its closest insiders.

The deadliest infectious disease of all time is curable

Tuberculosis (TB) is the deadliest infectious disease in history, having caused more than 1 billion deaths over the past 200 years. It is currently the leading infectious killer globally, recently surpassing COVID-19 to regain this status. TB has plagued humanity for thousands of years.

And yet, it is a preventable and curable disease. Most cases of active TB can be successfully treated and cured with a standard course of antibiotics. Tuberculosis death isn’t really caused by the bacteria anymore but by social determinants of health. Something should be done.

That’s from “Everything Is Tuberculosis: The History and Persistence of Our Deadliest Infection,” a March 2025 book by American author, novelist and Youtuber John Green. It is short, charming, insightful and harrowing. I recommend reading, and joining his cause.

“The real cause of contemporary tuberculosis is, for lack of a better term, us,” he writes. “So we have entered a strange era of human history: a preventable, curable infectious disease remains are deadliest. That’s the world we are currently choosing.”

Where the American policy of backing violent insurgents started

The Cold War was a sprawling, decades-long global imperial campaign advancing American-style capitalism. It worked, at least for those who orchestrated it. Anywhere any unaligned effort, and certainly any movement connected toward the Soviet communistic system, faced direct or indirect American military and special forces. 

Little known strategies from Indonesia and Brazil in the 1960s, as poorly known as they are, became models exported worldwide. That’s from The Jakarta Method: Washington’s Anticommunist Crusade and the Mass Murder Program that Shaped Our World, a 2020 book by American journalist Vincent Bevins.

As he writes: “I am not saying that the United States won the Cold War because of mass murder. The Cold War ended mostly because of the internal contradiction of Soviet communism, and the fact that its leaders in Russia accidentally destroyed their own state. I do want to claim that this loose network of extermination programs, organized, and justified by anti-communist principles, was such an important part of the US victory that the violence profoundly shaped the world we live in today.”

Below I share notes from the book for my future reference.

Guerrilla war follows long-standing principles that powers often overlook

Insurgencies are usually won or lost less by battlefield tactics than by political legitimacy. Once a population comes to see the dominant power as foreign (or foreign-backed), the occupier’s position becomes structurally fragile.

That’s the central idea of William R. Polk’s 2007 book Violent Politics: A History of Insurgency, Terrorism, and Guerrilla War, from the American Revolution to Iraq. Polk argues (across 11 case studies, which I summarized below) that insurgencies follow recurring social and political patterns, and that “hearts and minds” is ultimately a legitimacy contest that outsiders rarely can win on durable terms.  Polk (1929-2020) was a long-established political scientist, foreign policy analyst and former Dept. of State official.

It is common in history for guerrilla movements to succeed enough that some leader thinks it’s time to go more traditional in their war. But this is missing the lesson altogether: Conventional war is for defense but offense benefits from guerrilla. Below I share my notes for future reference.

Great men are rarely good; good men are rarely great.

Great men are rarely good; good men are rarely great.

This perspective has long influenced my thinking, and it comes to mind again in the context of the longstanding rivalry between the late Apple cofounder Steve Jobs and Bill Gates.

I was always uncomfortable with people valorizing Jobs, because the track record seemed clear: he treated people very badly. Meanwhile, Bill Gates has done objective good with his wealth since. And yes, rehabilitating a reputation by investing in meaningful global health projects… that is a good.

But, though we don’t know the final word on the Epstein files, Gates’s relationship there does not look good, especially in light of a noncommittal interview done by his ex-wife Melinda.

A History of the Eleven Rival Regional Cultures of North America

There was not just one American war for independence, and there are whole nations inside the United States that do not conform to state boundaries. Linguists in accents, anthropologists on material culture and political scientists on voting patterns recognize this.

That’s from American Nations: A History of the Eleven Rival Regional Cultures of North America, the influential 2011 book by writer-researcher Colin Woodward. It sparked much follow-on research, and the Nationhood Lab, which continues developing the book’s premise today.

Below my notes for future reference.

A vision for Philadelphia 250 years in the future

I’m deeply proud and honored to have helped develop a vision statement for Philadelphia for the next 250 years. An earlier version was shared last summer here. I shared this new version more widely for one last round of resident feedback in an Inquirer op-ed here.

The statement, a place to give feedback and information on the process can be found at PH.LY.

Below is the vision statement as it stands now.

The Gulf War Did Not Take Place

The Gulf War was a seemingly decisive military action led by the United States against Iraq in 1991.

Over a series of essays, French philosopher Jean Baudrillard argued the war was an expression of his concept of “hyperreality,” in which emerging visual media could be used to create something false that appears even realer than reality itself.

By 1995, he assembled these essays into a final, short book called The Gulf War Did Not Take Place.
