Look for the bottom of the world and you will not find it. Every floor you reach turns out to be standing on another. Nothing carries its own weight. Eighteen centuries ago a philosopher in India followed this thought further, and more honestly, than anyone before him or since. His name was...

What if one life is simply not enough?At thirty-five, Boris Kriger set out to live a thousand of them. He washed floors and wrapped the dead, escaped the claims of two armies, crossed countries and languages, built businesses, wrote books, studied medicine and cosmology, bought a house in a...

Nothing in this book can be seen.The forces that hold the world together announce themselves only through their effects: a needle that twitches, a filing that stands on end, a wire that jumps when nobody has touched it. For most of human history this was taken as evidence that such forces were...

In the autumn of 1934, in the garden behind a physics institute in Rome, a group of young men lowered cylinders of silver into an ornamental pond with goldfish in it, and discovered slow neutrons. The pond was not chosen for its elegance. It was chosen because it held water, it was ten steps...

His family cut stone in Salzburg for three generations. Christian Doppler was too frail to lift it, so he was sent off to do arithmetic instead, which everyone agreed was a lesser calling. In May 1842, in a half-empty room in Prague, he stood up before a learned society and explained why the...

In 1948 a shy, unicycling engineer at Bell Laboratories published a paper that quietly rebuilt the twentieth century, and he did it by refusing to answer the most interesting question in his field. Claude Shannon wanted to know how much could be sent through a wire. He did not want to know what...

He left school at fifteen to learn his father’s wool business, used his position as a company officer to keep himself out of the trenches, and sat his high school examinations at the age of twenty-four alongside boys nine years younger. Then he founded the most bookish school of thought of the...

A century ago, an American philosopher made a claim so simple that almost no one believed he meant it. William James said there is nothing hidden behind our experience. No invisible matter propping up the world from below. No cosmic Mind holding it together from above. Whatever joins one moment...

Everyone knows the headline. Heisenberg proved there are things we can never know. It is the most quoted result in modern science and one of the most thoroughly misunderstood, and this book explains why the misunderstanding has survived so long and what the discovery actually was.In 1925 a...

On the night of 25 March 1655, a young Dutchman aimed a telescope he had ground himself at Saturn and noticed a faint point of light beside it. He wrote it down and went to bed. That point was Titan, and while he watched it, methane rain was falling into rivers that had been cutting channels...

NASA had a problem. It wanted to know whether there was life on Mars, and the only way to find out appeared to involve landing a very expensive machine on it and scraping the dirt. The consultant they hired suggested something cheaper. Do not look at the ground, he said. Look at the air. A...

A Quaker schoolmaster who could not tell a scarlet geranium from its leaves, and who believed until his dying day that the fluid in his own eyeball was tinted blue, gave chemistry the one thing it had been missing for two thousand years. It was not the atom. Atoms were free. Democritus had them...

A Greek poet left behind a single line about a fox and a hedgehog. Twenty-six centuries later, an Oxford professor who had watched a man torn apart by a crowd in Petrograd turned that line into the most famous classification in modern thought, then spent the rest of his life insisting he had...

Als Denker von tiefgreifender Originalität und berüchtigter Schwierigkeit bleibt Martin Heidegger eine der umstrittensten Figuren des 20.

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.

You wake up every morning convinced that someone is home. There is a self in there, you assume, a small steady captain at the wheel, the same one who went to sleep the night before, the same one who will sign your name and remember your childhood and answer when called.

Everyone who writes about Henry Miller begins by taking a side. Either he was a liberator who tore the last Victorian veil off human life, or he was a vulgar egotist who mistook his own appetites for wisdom. This book refuses both chairs at that tired table.

If François Rabelais were alive today, he would not be “problematic” — he would be impossible. His books would not be debated, contextualized, or gently criticized; they would be reported, flagged, algorithmically buried, and ceremoniously uninvited from public life.

How do we tell the difference between knowledge and a story that merely sounds like knowledge? For most of the twentieth century, one answer dominated. A claim deserves the name scientific, Karl Popper argued, not because it can be proven, but because it can be proven wrong.

Nobody read him. Not one of his discoveries entered science through him. Every single one had to be found again, from scratch, by people who had never heard his name.This is a book about what that costs — and about the method that produced the discoveries in the first place. Leonardo da Vinci...
