  So let me remind you,  This is "the official dogma",  Maximize welfare, by maximizing freedom Maximize individual freedom, by maximizing choice The one that we all take to be true,  and It's all false,  It is not true .  There's no question that some choice is better than none.  But it doesn't follow from that  that more choice is better than some choice.  There's some magical amount, I don't know what it is.  I'm pretty confident that we have long since passed the point  where options improve our welfare.  Now, as a policy matter, I'm almost done.   As a policy matter, the thing to think about is this,  what enables all of this choice in industrial societies  is material affluence.  There are lots of places in the world,  and we have heard about several of them,  where their problem is not that they have too much choice.  Their problem is they have too little.  So the stuff I'm ta...

  After all, it's about survival of the fittest. But survival of the fittest what? I mean, most people think of natural selection as being about the survival of the fittest individual? animal? Individual Individual  Individual  Animal - (group)  Animal?  Okay, so it's like an individual.  Yeah.  Which makes sense. I mean, individuals best adapted to their environment have increased odds of survival and therefore a higher likelihood of passing on their genes.  So it follows that each individual should do everything it can to survive and reproduce.  That is, it should be selfish .  But if that's true, then how do you explain this?  Worker bees will sting predators to protect the hive, even though it might kill them in the process.  Female worker ants are sterile, so they can't reproduce, but regardless, they work for the colony for their entire lives until they die.  Monkeys adopt orphans,  Wolves bring meat to non-hun...

  We call the point where those two curves meet the equilibrium. The point where supply and demand are in agreement is the equilibrium. That is the point at which suppliers are willing to sell roses at the same price consumers are willing to pay for them. So with 600 roses, 600 boxes of roses or whatever it is the equilibrium price is $3.  Well, it's a rose, So with 600 rose the equilibrium rice is $3. That is, both parties are happy in equilibrium. The key point about equilibrium , as the name implies, as the term equilibrium implies, It's the point where the system has come to rest.. Where both parties are happy with the outcome.  Both parties are happy because it's on the demand and supply curve. Since it's on the demand curve, consumers are willing to pay $3 for 600 roses. They wouldn't pay $4 for 600 roses, but they'd pay $3.  Since it's on the supply curve, suppliers are willing to accept $3 for 600 roses. They wouldn't accept $2 for 600 roses, but...

  The next question was what makes them go around?   Or how can we understand this in more detail?  Or is there anything else to say?  In the meantime, Galileo was investigating the laws of motion. Incidentally at the time of Kepler, the problem of what drove the planets around the sun was answered by some people by saying that there were angels behind here, beating their wings and pushing the planet along around the orbit. As we'll see that answer is not very far from the truth the only difference is that the angels sit in a different direction, and their wings go this way.. But the point that the angels sit in a different direction is the one that I must now come to. Galileo in studying the laws of motion and doing a number of experiments such as seeing how balls rolled down incline planets and how pendulums swung. and so on. Discovered an idealization, a great pinciple called the principle of inertia, which is this that if a thing has nothing acting on it, if an o...

I'm an identical twin. And I've always gotten along absolutely perfectly with my twin sister. Her name is Lorna, She lives in france. She's a very fine painter and She shows in Paris and Actually also in China and Japan.   She's a fine painter.  We've never had an argument. And one thing about being an identical twin is everybody asks you about yourself. Everybody does.  Do you have the same cavities in your theeth?  Do you like the same food?  Do you have the same friends?  Everybody does And one time we were maybe around eight or nine. And we were told to assemble in the foier of our house, when one of mother's friends came over. She leaned down to me and she said, asked the standads questions. And then she said,  Do you think alike?  And at the time, I thought to myself as I looked up at her.  Well how would I know how she thinks? I mean that's ridiculous. But I came to realize that there are patterns to personality that are genetical...

  If you want to know if someone really understands evolution, just ask them this one weird question .  Why does poop smell bad?  Oh... Oh, gosh. Because it has bacteria in it, I guess?  Microbiome, probably.  Trash- Yeah, trash from the gut of the body.  The food we eat?  Because of the chemicals?  Farts don't always smell bad.  Yeah. Well, that's a different question entirely.  Do you think it objectively smells bad?  Yes, I think so. Yes.  How do you think it smells to flies?  Like the fly?  Yeah- They like it. They love it.  They like it, yeah. They love it.  Animals love stinky things. Yeah.  They're attracted to it.  Poop smells good to flies because poop is full of nutrients. They use it as food. But it's also full of bacteria that can be life-threatening to humans.  So the real reason poop smells bad to us is because if anyone ever thought it smelled good, they would pro...
