"Since we can never know anything for sure, it is simply not worth searching for certainty; but it is well worth searching for truth; and we do this chiefly by searching for mistakes, so that we can correct them. Science, scientific knowledge, is therefore always hypothetical: it is conjectural knowledge. And the method of science is the critical method: the method of the search for and the elimination of errors in the service of truth." —Karl Popper, In Search of a Better World.

Bangladeş’te bir İslamcı, elinde silahla tıp fakültesini basıp "Kadınların eğitilmesi haramdır!" diye bağırıyor. Önce "Başörtülü bacımız okula giremiyor" diye mağduriyet yaratanlar, güçlenince "Kadının okula gitmesi haram" demeye başlıyor. Olan yine geleceğe oluyor… 🇧🇩

Cute theory, let's play it out. A monkey hoards a trillion bananas. The troop, enraged, beats him to death. They gather around the pile to feast at last. But... oh wait, there is no pile. It turns out the "bananas" were shares in a banana-launching company the dead monkey founded. The shares were worth a trillion because he was alive to run it. Now he is dead and the stock is worth $0. The retarded monkeys have clubbed their way into a recession. But it gets worse. Half the "bananas" were tied up in a rocket that supplies bananas to monkeys on the far mountain who had no bananas at all. Another chunk was tied up in a little satellite dish that beamed banana coordinates to the troop after a flood took out their trees. So now they realized they beat to death the only monkey who knew how the dish worked. So the monkeys sit there. No bananas. No rockets. No coordinates to get more banananas. Just a dead body and a powerful sense of fairness as they all now became infinitely poorer. OH And somewhere a smaller monkey watches the whole thing and quietly decides he will never build anything in front of these animals again.

“To follow socialist morality would destroy much of present humankind and impoverish much of the rest.” Economist Friedrich Hayek pointed out that no group of planners has enough knowledge to run an economy. @ryanmcmaken of @mises explains why Hayek’s ideas matter today:

Most people don't understand the difference between having billions in the bank, liquid, & having ownership shares in companies worth billions. And I think it would behoove the media to explain this once in a while.

Been brushing up on the discourse and I’ve decided that every single person is richer than me is a greedy bastard and every single person poorer than me is a loser. I and only I have the exact right amount of money.

136 kilos de cheveux de femmes iraniennes retrouvés dans des camions en provenance d’Iran par la douane arménienne depuis janvier 2026. Cela fait des mois que nous alertons sur la disparition des corps de femmes iraniennes massacrées en janvier, que nous dénonçons les utérus prélevés sur certains cadavres… Aujourd’hui, l’horreur atteint un nouveau degré avec ces images de cheveux saisis par centaines de kilos. Pourquoi un tel silence de la communauté internationale face à ce régime barbare ?

A lot of people seem angry that Elon is now a trillionaire, so it’s worth reminding them that he didn’t achieve this by making anyone else poorer. Wealth isn't zero-sum. Paul Graham explained it well: paulgraham.com/wealth.html

Every single person who still cringes at the memory of trying to bullshit their way through an interview or exam question: today, the slate is wiped clean. Set down your burden of shame. Nothing - nothing, I say - could touch this.

Elon Musk did not become a different person when he landed in America. In South Africa, he may still have been brilliant, restless, and ambitious, but the environment would not have given him the same room to build SpaceX, Tesla, Neuralink, and everything else. Talent matters. The country you build in decides how much of that talent can become real.

Elon’s stock holding value is because people think/hope he is going to do fabulous good for billions of people. What an age we live in! So instead of sniping let’s hope they are right. If they aren’t he will be worth far less and all of humanity will be poorer.
Elon Musk just became the world's first trillionaire. The typical American household would have to work more than 11 MILLION years to make Elon Musk's level of wealth. We need a wealth tax.

A lovely example of using imagination to get what needs to be done done, rather than being stymied by organisational rules “computer says no”.
In 1920, six-year-old Nancy Bentley was bitten by a venomous snake near Port Arthur, Tasmania. With her condition worsening and medical help far away, her father rushed her to HMAS Sydney, a Royal Australian Navy warship anchored nearby. A problem quickly emerged: naval regulations at the time prohibited civilians from receiving treatment aboard warships, and women and girls were not allowed on naval vessels at all. Determined to save her life, Captain Henry Cayley came up with an extraordinary solution. Nancy was officially enlisted into the Royal Australian Navy and given the rating of "mascot," making her a temporary member of the ship's crew. This allowed doctors to legally treat her onboard. After receiving care, Nancy recovered and was formally discharged from the Navy just eight days later. The remarkable incident made Nancy Bentley both the first female and the youngest person ever enlisted in the Royal Australian Navy.. a title she still holds more than a century later.

In a famous 1972 televised debate, David Susskind argued that a woman could not be president because of the hormonal changes that occur during menstruation. ⁠ ⁠ Germaine Greer immediately put an end to the debate by asking him if he could tell whether she was menstruating at that very moment, which left his argument without a response.⁠
