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.

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.

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 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.

The Blank Slate: The Modern Denial of Human Nature

Fri, 13 Jun 2025 00:00:00 +0000

The Blank Slate — the belief that the mind arrives empty and is shaped entirely by experience — has always looked like the safe, decent position. If nobody is born with fixed traits, then everybody starts equal and any inequality is society’s fault, fixable by reform. Steven Pinker’s argument is that this comfort is an illusion. Equality is a moral commitment about how we treat people, not a prediction about what biology will find. Confuse the two, and every discovery about genes or brains starts to feel like an attack on justice itself.

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.

Behave

Sun, 08 Mar 2026 00:00:00 +0000

Pick any human act — a stranger pulled from traffic, a village burned to the ground — and Robert Sapolsky, a Stanford neurobiologist, wants to know what caused it. Not the single tidy reason, but every layer at once: the neurons that fired a second before, the hormones circulating that week, the childhood and the womb, the genes, the culture, the ecology stretching back generations. Boiled down to one phrase, his answer is “it’s complicated.” Nothing causes anything by itself; everything just modulates something else. That sounds like a shrug until you follow it to the end, where it quietly dismantles the case for punishing people at all.

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.

The Prince

Wed, 22 Jul 2026 00:00:00 +0000

Machiavelli wants to tell you how power actually works, not how moralists wish it worked. Plenty of writers have imagined republics and princes that never existed. He wants the real truth of it, and the real truth is uncomfortable: how people actually live is so far from how they ought to live that a ruler who insists on being good in every situation, surrounded by people who are not, will ruin himself. So a prince has to learn how not to be good, and to use that knowledge or withhold it depending on what the moment demands. Holding a state you inherited is easy enough; you mostly just avoid breaking with your ancestors’ customs. The hard case, the one this book circles, is the new prince building authority from nothing.

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.
