The Immortal Life of Henrietta Lacks

Tue, 24 Oct 2023 00:00:00 +0000

Some of medicine’s greatest gifts were extracted from people who were never asked. Henrietta Lacks is the clearest case. A Black tobacco farmer and mother of five, she died of cervical cancer at Johns Hopkins on October 4, 1951, after radium treatments failed. During those treatments, the biologist George Gey took a sample of her tumor without telling her or her family. Those cells — labeled HeLa — became the first human cells to survive and reproduce indefinitely outside the body, doubling every 24 hours. They seeded the polio vaccine, chemotherapy, cloning, gene mapping, and in vitro fertilization, and even rode the first space missions to test human cells in zero gravity. Trillions more of her cells now grow in labs than ever lived in her body. Her family had no idea.

Bad Blood: Secrets and Lies in a Silicon Valley Startup

Wed, 30 Aug 2023 00:00:00 +0000

Silicon Valley loves a founder who fakes it until they make it, and that tolerance is mostly harmless — right up until the product is a medical diagnosis. Theranos is the story of what happens when it isn’t. Elizabeth Holmes, who feared needles and had wanted to be a billionaire since she was ten, sold an irresistible pitch: a credit card–sized device that would draw blood from a single pinprick, feed it to a toaster-sized machine called Edison, and test for over 200 diseases cheaply, in every home. By 2014 the company had reached a $9 billion valuation and signed deals with Walgreens and Safeway. The device never worked.

The Republic

Tue, 20 Jun 2023 00:00:00 +0000

Justice, for Plato, is not fairness or rule-following in the everyday sense. It’s order — the right thing ruling in the right place, both inside a person and inside a city. Across the Republic, Socrates works toward a single definition: justice means each part performing its proper function. In the soul, reason should govern appetite; in the city, the wise should govern the many. And because a soul and a state mirror each other, a society falls apart exactly as fast as the character of its citizens does.

All About Love: New Visions

Sun, 13 Apr 2025 00:00:00 +0000

Almost nobody can tell you what love actually is. It saturates our songs and films, usually as a male-dominated fantasy, yet it barely enters serious public conversation, and without a shared definition people flail. They mistake a rush of feeling for love, or need for it, or even abuse for it. bell hooks borrows the definition she finds most useful, from M. Scott Peck: love is “the will to extend one’s self for the purpose of nurturing one’s own or another’s spiritual growth.” The key word is will. Love is an intention and an action, which means it is a choice. We do not love instinctively; we decide to. And anything you can choose, you can learn to do better.

Beyond Good and Evil

Fri, 05 Apr 2024 00:00:00 +0000

Start with the question no one asks: why do we assume truth is worth more than illusion? Nietzsche opens by refusing the comfortable binaries—true versus false, good versus evil—that hold up nearly every philosophy ever written. Those oppositions aren’t discoveries about the world. They’re the philosopher’s own prejudices, promoted to the rank of universal law. In fact, he argues, every philosophy is “a kind of involuntary and unconscious memoir,” a confession of the temperament that produced it. Before you can think honestly, you have to be willing to crush your own moral prejudices and descend somewhere less flattering.

Eating Animals

Fri, 09 May 2025 00:00:00 +0000

Cheap meat is a magic trick, and the trick is keeping you from looking. Jonathan Safran Foer set out to see exactly how the animals we eat are raised and killed, and what he found is a system engineered around consumer ignorance. The low price on a package of chicken isn’t real. It exists only because the true costs — to the animals, to slaughterhouse workers, to rivers and air, to the climate — are paid out of sight. Look directly at the process and cheapness stops working as a defense.

The Art of Loving

Thu, 24 Oct 2024 00:00:00 +0000

Most people treat love as a problem of being loved, not of loving. You assume that if you can make yourself attractive, successful, or interesting enough, the right person will appear and love will simply happen to you. Erich Fromm says this has it exactly backward. Love is an art, a discipline you develop the way you’d develop any real skill, and almost no one bothers to learn it because we’re all too busy trying to be lovable.

The Righteous Mind: Why Good People Are Divided by Politics and Religion

Thu, 22 Aug 2024 00:00:00 +0000

Your moral convictions feel like conclusions you reasoned your way to. Jonathan Haidt argues they’re nothing of the sort. The verdict—that’s disgusting, that’s unfair, that’s wrong—arrives first, in a flash of gut feeling, and your careful arguments show up afterward like a lawyer hired to defend a client who’s already been chosen. Get this backwards and you’ll never understand why political and religious arguments so rarely move anyone, or why people on the other side look not just mistaken but morally rotten.

Permanent Record

Sat, 15 Mar 2025 00:00:00 +0000

The same internet that made life convenient made it cheap to watch everyone at once. That is the discovery at the center of Edward Snowden’s memoir, and he made it from the inside, as a contractor with the keys to the United States’ surveillance machinery. Centralized servers, undersea fiber-optic cables, and quiet partnerships between the government and the biggest tech companies turned blanket, retroactive surveillance from a technical fantasy into something trivial to run by default. Snowden’s argument is that when a capability becomes that cheap, it gets used—and that a society which accepts it has quietly decided its citizens have no rights worth protecting.

Life 3.0

Sat, 03 Jan 2026 00:00:00 +0000

Intelligence is goal-achieving computation. Strip away the mystique and that’s all it is — the ability to accomplish complex goals — and nothing in that definition requires flesh, neurons, or a billion years of evolution. Max Tegmark’s whole argument rests on this: “matter doesn’t matter.” Memory, computation, and learning are physical processes that non-biological matter can run just as well as brains do. Which means a machine could one day out-think us, and the trouble it causes won’t come from hatred. It will come from competence aimed at the wrong target.

A Little History of Philosophy

Mon, 14 Oct 2024 00:00:00 +0000

Philosophy’s real achievement isn’t a stack of settled answers. It’s a relay of sharper questions, handed down. Every thinker since Socrates took something that looked obvious — about God, knowledge, the self, justice — and pushed until the certainty cracked. What you inherit from 2,500 years of argument is a set of tools for examining your own life, not a doctrine to memorize.

Careless People: A Cautionary Tale of Power, Greed, and Lost Idealism

Thu, 20 Mar 2025 00:00:00 +0000

Sarah Wynn-Williams talked her way into Facebook because she believed it could do what governments couldn’t. She’d watched the platform coordinate rescue and relief after the Christchurch earthquake when official channels failed, and after years as a UN diplomat frustrated by bureaucracy, she was convinced this was where one person could actually change things. She pitched the company on a global policy role and got it. What she found was the opposite of what she’d imagined: a leadership so cushioned by wealth and scale that its decisions had come unmoored from their consequences, inside a company that treated anyone who named the harm as the problem.

Just Mercy

Thu, 23 Jul 2026 00:00:00 +0000

A young lawyer walks into a maximum-security prison and comes out changed. Bryan Stevenson was twenty-three, a Harvard law student unsure he even wanted to practice, when an internship sent him to Georgia’s death row in 1983 to deliver one message to a condemned man: you will not be executed in the next year. He expected disappointment. Instead the prisoner, Henry, wept with relief, talked with him for three hours, and, as guards shoved him out in shackles, planted his feet and sang an old church hymn. His argument, built over three decades, is blunt and hard to shake: our justice system condemns people too easily, punishes the poor and the Black most harshly, and makes terrible, irreversible mistakes. Under it runs a single conviction. Each of us is more than the worst thing we’ve ever done.
