Why do we do math in school? When I asked this question as a kid, my teachers always told me, "You'll use it one day." That's almost always false. Most adults are never going to be in a sticky situation with two binomials, thinking, thank goodness I can FOIL...

.David Deutsch: Bertrand Russell and Whitehead spent 300 pages or whatever it was proving that 1 plus 1 is 2. And then it was realized that you can't define things by axioms anyway, because there's no such thing as proving that an axiom system is consistent. Godel proved that. Alex O'Connor: Yes, the Godel's irresoluteness theorem. David Deutsch: Yes. So this search for justified truth, even in pure mathematics where you might think that, you know, true, there's unambiguous truth about numbers 2 and 1 and equals and plus and so on, but it's not true. That whole system is just a conjecture. Alex O'Connor: Okay. So to be clear, when you say we can't have truth, you're not implying that, you know, there is no truth and truth and falsia. You mean literally that we can't have it. It's there. It's just that we can never have it because we'll only have something like half truth. So, for example, if I said to somebody, like, every homo sapiens, every human being under the age of six is an ape. That's true. David Deutsch: Yes. Alex O'Connor: But it's like there's something missing from that picture. It's kind of misleading. It's going to lead us into all sorts of trouble if I'm not more clear. And so, okay, what I mean to say is that every human being is an ape, but then that itself will rely on understandings of what taxonomy is and categories. And if you really want to get the fullness of truth in every possible respect that could even possibly be relevant to that statement, you'd probably basically require like infinite knowledge, right? Because you would need to understand how language works. You'd need to understand taxonomy. You'd need to understand like the philosophy of taxonomy. You'd need to understand whether objects can exist. You'd need to study myriology and parts, and you'd need to know all of this. And the only reason that we don't on a practical level need that is because on a practical we only ever go so deep. David Deutsch: We only ever go as deep as is needed to solve the problem that we're currently solving. Alex O'Connor: I see. I see. And so knowledge becomes relatively practical because if you can't have knowledge in the sense that the philosophers define it, then when people are talking about things that they know, they're getting at something slightly different, which is like a practical certainty or a practical confidence. David Deutsch; Well, practical is the wrong word because it need not have any practical application as in vacuuming your carpet. It might be an issue of pure mathematics. It might be an issue of pure mathematics that only you are interested in, and yet it's still knowledge. What we are seeking is knowledge, but it's not truth. We can find knowledge in the sense that we can correct existing knowledge by removing errors. And that's what the growth of knowledge always is. It's always removing errors. When I realize what you meant by first left and second right, it's by removing the misconception that I had before. It's not that what you told me is false or that the idea that I had is entirely false through and through. It contained truth. Both of them contained truth. Both of them contained error. To get to my destination, it's enough if I remove errors to the extent that they are relevant to the problem that I want to solve. Alex O'Connor: Is there anything that you know is true? Like in the Cartesian sense of, I think, therefore I am. Maybe that's all I can know with certainty, but is there anything that comes to mind? David Deutsch: No. I can think of things that are more certain than that, which are still not certain. There is no such thing as certain truth. Descartes was already assuming that such a thing as I exists, and yet these experiments with memory, first of all, memory in any case consists of confabulation. When we remember something, what we're really doing is conjecturing what happened using the structures in our brain as clues to test our conjectures against. This process is fallible. In particular, the statement, I think, is extremely fallible because there are now experiments you can do to show that people have false memories of having thought something that they couldn't possibly have thought because they didn't know the thing they were thinking about, that they thought they were thinking about at the time.

my new song “BREAKDOWN.” is out on the 21st of June!!! 🖤🖤🖤 I wrote this poem because it’s been the hardest year for my mental health. In my life I’ve always never felt good enough, it’s just the thing that’s eaten me up. For as long as I can remember i have felt constantly afraid of how quickly my head can turn dark. It’s always been so hard to fight the darkness that i inevitably have. A lot of people will say it’s a phase and it will go away. But it doesn’t and the reality of the situation is I have to find strategies to deal with it. To put it plainly the things I don’t like about myself will probably never change, people tell me one day I’ll come-to terms with them one day but I want that day to be FUCKING NOW. This song is a message to myself to try and exist alongside my insecurities and my darkness by grounding myself and remembering what is real in life and the world is so much bigger than me. Try and get out of your head and notice the world around you, notice the things and people around you. Connect with them, the chances are they probably feel the same. Don’t let the bullshit inside your head consume you. It just wastes precious time. Remember what is real. Help people, be kind, help the world, help yourself. If you think you can’t do it, you can. You can get through this, trust me. Use this poem in a mornin to get u out of bed, use it when youre about to back out of something last minute, use it when you’re at your darkest. It’s got a little bit of light in it. Don’t forget to put your feet in the grass … Mind

🛑 Burkina Faso 🇧🇫 - Captain with school boys and girls! The young Captain was having a conversation with the pupils, and here is what he saying, “I was telling you a while ago, in school they were telling us that we couldn’t do it here. They lied to us. We grow wheat here, and it works well, and we will develop it. Some people have started, this year, I was able to see people who did it, as part of the presidential initiative, and I was told that in the past, some were able to do it and they produced it well. Currently, we are sowing wheat in some farmlands as part do the presidential initiative. What you eat must be produced here. So, this is why I say that we will teach you many things, and we will review the curricula they teach you. For those who drink coffee, they told us that your coffee, chocolate, it is only in the countries with abundant rainfalls, that here is only savanna, desert, it does not rain, we cannot farm. Again, they lied to us. It’s not true! Coffee grows well here, cocoa grows well too. There are people here who have the farms here, even in Ouagadougou here, there are people who have cocoa trees in their yards. This means that, chocolate that children envy those from well to do familes can be manufactured here in Burkina and all the children can eat chocolate in Burkina. We found out it is possible. As for milk, why do we have to import it? We can do it. I just want to tell you that there are many things that they never told us the truth about. You guys are lucky, we are now teaching you, and we promise you that we will do all we can so that you can eat your fill. As we say, you will eat well in the morning before you go to school, you will go to school for free, you will eat lunch, you will have fun, and in the afternoon, when you return home, you will have fun in the neighborhood, then in the evening, you will learn and review your homework and sleep. This is the dream we have. As long as the children in Burkina are not in these conditions, our fight will not stop. Ok? (Claps). So, we know these are your aspirations and it is right and legal. Any parent is fighting for this. Even those who do not have children fight in the hope of having children and to take care of them, so that they can live in better conditions, and be better than them. This is the fight of everyone, this is the fight of every generation. We are lucky God gave us everything. Do you know that everywhere in Burkina we can farm? Everywhere! In the Sahel where they tell you it is the desert, it is only sand, we can farm. As for us, we have been lied to so much, it is the brainwashing of the colonizer. He did that so that we may not think 💭. But we finally found out that everything was a lie ( damn lie, emphasis is mine). If God left many lakes in that desert, He knows why. We can farm everything in Burkina, we can do everything, the land is fertile. And there are so many natural things in Burkina that we never planted but they were here, isn’t it ? Have you ever learned how to plant a shea tree in Burkina? You were born and found them already here right? It is there in the wild in nature. You know it is a gift from God. There are many things in the shea fruit. You have the shea butter, that is oil; do you know that there is chocolate in it? There are seven derivatives in the shea fruit. You also have the Parkia biglobosa (also known as the African locust bean) which is a natural fruit. We have many things, it is not only the minerals in the soil. Even with the soil, we were told that it’s ferralitic soil, that it is not fertile, everything is a lie. You see that today there is so much gold in Burkina. But it is just poorly managed. Our mission is to well manage these resources, and to take good care of you, so that you can be in your basic rights, to lead a good life, to go to school, and that we may protect you. And also that you may fulfill your duties, because your duties are very important, aren’t they?…

Algorithms and the Affections John Piper (Nov. 2025): “If you had thought that your essence of humanness in the image of God was your reasoning capacity, over an ape or a porpoise, you’re in trouble. Because, guess what? ChatGPT is smarter than you are and more creative than you are in expressing things in language that is good. It can write prayers better than you can, and it can reason through hard problems better than you can. Therefore, there are people who are going to forsake the faith because they thought to be a human in the image of God was to be a reasoning person over against the animals, and they discovered a machine can do it better than they can. Crisis of faith. This to me is no crisis because of my Christian Hedonism. I do not think that my reasoning capacities are my essence. I think the soul’s capacity to delight in God is my essence. The soul’s capacity to enjoy God. No machine will ever enjoy, period. It will have the language of enjoyment. You can tell it to write a poem of enjoyment and it will use the language. That machine is not enjoying *her*. It’s not. It never will. Only human beings created in the image of God can enjoy God. Therefore, enjoyment matters. I mean, affections are who we are ultimately. The end of history, the end of creation, is not going to be merely rational creatures thinking rightly about God, little computers. It’s going to be people who are so perceptive spiritually of the glories of God that they are full of affections that are appropriate for those glories and can give expression to them. That’s what eternity will be.” Source: Sovereign Grace Churches, Pastors Conference PreCon (November 2025)

To My Day. 🐻: But really as I always say, the reason our concerts can be so fun is really because of you! I'm not just saying this~ When people come to our shows, the friends and family we've invited always say the same thing. I mean sure they say our songs are good or that we sing well but those are kind of like extra factors. They always tell me "Your fans are insane!" Your energy and the atmosphere we create together is honestly what makes the concerts so fun and makes people want to come! That's why we always tell you that you're really people who can do well no matter where u go! That's how we see you! Seriously! So you should feel proud of yourselves! Not just proud of us but proud of yourselves too. Because the way we see you is filled with pride as well. That's why why we can think and speak this way. But for real, thank you. I'm really grateful for the kind of relationship we formed in the first place, but I'm even more thankful that you kept it going like this. I really appreciate that. So, this is not about raising your self esteem. This is really what we see. You know me. I'm not the type of person who says things I don't mean. I can't even make up things even if I wanted to and it's obvious when I lie. So what I say is coming straight from my heart, so I hope you can just take it as it is because that's how I really see you. I don't know what our individual lives are like outside the concert venue because I've never seen that. But you all seem people who can do anything. And you always show that at our concerts. That's how trust builds with between us. But honestly, you do all really sing well. Even better than us at times. We try our best with harmonies and all. But like what you during the fanmeeting*, you pull everything together and leave people amazed. That's just how it is. Just the fact that it keeps coming back in conversations says something, right? I think so too and I felt it back then. It was so touching. If something can move me to tears, and I'm someone who makes music, I'm a singer... but the fact that you made me feel that way, that's saying something. And I'm someone who sings for a living. I have such high standards but you were able to touch my heart like that, then I think it would be the same for anyone watching. The emotions really come through. And I think that's ultimately the most important thing. *

Bret Weinstein cuts straight to the chase: "We are going to have an endless battle in which those of us who see what we believe is clear evidence of some kind of election rigging or fraud are faced with indignation from a vast array of people portraying themselves as more rigorous and careful who say, 'Where is your evidence? Where exactly is your evidence that there was something wrong with this election?' And we are gonna be caught in the following predicament. No piece of evidence is sufficient to establish that case. And the sum total of all of the evidence contains true things and false things. So it is also no good. So the question is, can you logically deduce that something has gone wrong? I believe you can easily. Can you prove it? No. And not being able to prove it means that the election will proceed. It will be validated by all of the structures, including the courts. And that means that those who take on the power that derives from these elections will be the result of whatever process we just went through, whether it was an election that happened to be anomalous through organic means, or it was the result of some kind of fraud or election rigging. That is not an accident. That is not an accident. And the point that I wanna make primarily is the primary evidence against elections that look like this being organic is not actually in the trickle of evidence that we are actually able to see, the moment by moment vote count that does something strange during the night when some large tranche of ballots is suddenly counted or something like that. The evidence is in the structure of how the elections are actually carried out. These elections are designed to allow fraud that cannot be detected and will not be prosecuted. And that's really the thing that we must focus on." Bret Weinstein
