In the space of a single year, a cautious German professor who disapproved of revolutions produced two numbers that would shape the century after him. One of them was measured. The other was manufactured. Nobody, including him, ever wrote the difference down. The first was the quantum of action, squeezed out of infrared readings taken by instrument builders in a Berlin laboratory founded to help the lamp industry sell brighter lamps. It was a real quantity, extracted from real dials, and it has survived every revision physics has thrown at it since.

He got the disease right and the cure wrong, and almost nobody noticed, because the disease was so well described that the listener arrived at the prescription already grateful. Alasdair MacIntyre spent forty years arguing that our moral vocabulary is salvage—words rescued from a wreck and used with conviction by people who no longer possess the framework that made them mean anything. He then proposed a remedy: that a human life has the unity of a story, and that we become answerable by knowing which story we are in.

Every description of anything is a projection. Physics describes the world in space and time; mathematics in number; philosophy in existence and cause. Each of these is a medium, and none of them need belong to the thing described. So a simple question follows, and it turns out to have a precise...

Nine hundred years before “think for yourself” became a slogan, Pierre Abélard, known to English readers as Peter Abelard, said it out loud in a world that answered such talk with fire and the knife. He argued that we should understand in order to believe, not the reverse. He insisted that guilt lives in intention, not in the deed. He held that even saints and scriptures could be wrong, and that doubt was not a sin but a method.

For a hundred years the cosmological constant has been served up as physics' most embarrassing riddle. Empty space, we are told, has no structure at all —no grain, no direction, no preferred place to stand —and yet it presses outward on the universe, stretching the heavens apart with a quiet, relentless force. How can the same nothing be both featureless and full of push? How can emptiness shove? This book answers by refusing the trick question. The word “structureless,” it turns out, smuggles two very different ideas into one.

For nearly eighty years George Orwell has been read as a prophet, which is a comfortable way of reading him, because prophecies are always about somebody else. This book reads him instead as an experiment that has now run its full course. The results are in, and they are worse than the prophecy.

Three men who believe themselves to be the Teacher, the Messenger and the Awakened share a locked ward, get along like brothers, and regard the hospital staff as the only genuinely disturbed people in the building. A fourth patient, who appears on no list, lies with the blanket over his head and sighs. When the consultant schedules them all for a lobotomy, they climb the highest mountain on earth without leaving the ward and ask God to make the human race slightly wiser. The results are not encouraging. They then try the opposite.

Every age believes it has finally found the one key that unlocks everything. In the nineteenth century it was Theosophy, the bold and improbable system assembled by Helena Blavatsky, who promised to braid together science, religion, and the vanished wisdom of the East into a single shining...

For sixteen centuries, the same mistake has been made by men who meant no harm: the mistake of confusing what belongs to the soul with what belongs to the state. The state can build roads, run courts, and supply clean water. It cannot save anyone. The soul can hold truth, suffer, and find peace. It cannot administer a city. When these two orders are mixed, the reaction is slow but inexorable. It produced the holy empires of Byzantium and Muscovy. It produced the secular messianisms of the twentieth century. It is producing, in milder forms, the political theologies of our own moment.

Carl Sagan established that the surface of Venus is hot enough to melt lead, that the seasonal color changes on Mars are blowing dust rather than creeping vegetation, and that the orange smog of Titan is made of complex organic molecules drifting down onto an alien shore. He briefed the Apollo astronauts. He designed the first physical message our species ever sent beyond the Solar System. He also spent a portion of his youth calculating, for the United States Air Force, what a nuclear detonation on the Moon would look like from Earth.

In an age when digital worlds are no longer fantasies but emerging realities, the question is no longer whether simulations will host conscious life — but whether humanity is prepared for the moral weight of creating it. The Ethics of Simulated Worlds confronts this new frontier with philosophical clarity and unflinching honesty.

In 1889 a broke ex-actor sat down to write a serious history of the River Thames. He meant to cover the abbeys, the charters, the battles, and the kings. His editor cut all of it. What survived was a book about three incompetent men, a fictional dog, a tin of pineapple that could not be opened, and a cheese so powerful it emptied a railway carriage. It has never once been out of print.

For a hundred years Martin Buber has been read with bowed heads. The gentle prophet of dialogue, the bearded sage who taught a tired century to say “Thou,” he became the conscience of a people and the symbol of an age. His slim book I and Thou is quoted everywhere and examined almost nowhere. This is the examination it never received.

He was not a doctor. He was admitted to the Academy of Medicine by a majority of exactly one vote, and once, after explaining to that same Academy where chicken cholera comes from, he was challenged to a duel by an eighty-year-old orthopedic surgeon who did not believe in germs and did not intend to start. Louis Pasteur also saved more human lives than anyone else alive in his century. The Invisible World follows him from a tanner's yard in the Jura to a crypt lined with gold mosaic, and argues that everything he did came out of a single stubborn conviction formed when he was twenty-five...

A shy Oxford mathematician who spent his professional life defending Euclid against modernizers wrote, almost by accident, the strangest books in the English language. For a century and a half we have explained them badly. We have blamed opium, blamed migraine, blamed a temperament we would...

This book tells the story of the Rubicon as a symbol that has refused to die—clinging stubbornly to the imagination of humankind from Caesar’s fateful step right up to our own modern dilemmas, those moments when we make choices that turn the world upside down. The river itself becomes more than water and stones: it becomes destiny incarnate, the line that separates what was from what will be, hesitation from decision, trembling fear from reckless courage.

We are the first people in history to be free in theory and stalled in practice. We have more choices than any generation before us and somehow fewer lives actually lived. We rehearse our existence endlessly—planning, optimizing, curating, postponing—while the thing itself keeps getting moved to next quarter, next year, the version of us that has finally gotten it together. Jean-Paul Sartre had a blunt name for this kind of self-deception: bad faith. He thought it was a private failing. It has since become a business model.

Why does every prosperous society keep manufacturing the same private griefs? The names change with the decade, but the shape does not: addiction that slides from one substance to the next without ever loosening its grip; anxiety that arrives without an enemy; the slow erosion of the bonds that were supposed to hold a life together; the quiet exhaustion of the generous, who keep a community alive until they themselves go dark. We treat each of these as a separate misfortune with a separate cure. This book argues that they are not separate at all. They are the symptoms of one missing thing.

Pavel Florensky was a priest who electrified a godless state, a mathematician who defended holy folly, and a theologian who insisted that the deepest truths arrive in pairs that refuse to be reconciled. He stayed in Russia when the door to escape stood open, and the century that ground him to dust on a prison island has spent the decades since not quite knowing where to put him. Too philosophical for the Church, too devout for the academy, too playful for the martyrologists, he remains gloriously unfiled. This is not a biography in the ordinary sense, and it is certainly not a canonization.

Everyone remembers Denis Diderot as the man who tried to squeeze all the knowledge in the world into one enormous alphabetical order. Almost no one notices where he actually hid his most dangerous ideas. Not inside the entries, where the censors were looking, but in the invisible links between them. A page on cannibals that quietly points the reader toward a page on Holy Communion. Each entry innocent on its own. Together, a small controlled explosion. This book argues that Diderot's real invention was not a reference book at all.
