The test of a first grade intelligence is the ability to hold two opposing thoughts in mind at the same time, and still retain the ability to function. It's funny because one of my I'm going to use a quote to explicate a quote. So one of my other favorite quotes is, I don't know who discovered water, but I thought it was a fish. And we have no insight into the way language and our brain chunks the world. But if you look at things, the prefrontal cortex is essentially binary. So when you look at things like black, it's in contrast to white or boy, it's in contrast to girl or tall, it's a contrast is short.

So our mind basically breaks things into two opposing things. And in my classes, I always show those optical illusions like rabbit duck or old woman knew a younger woman. And that was funny what I just did you hear that? I said, old woman, new woman. So you see what see how the mind works it. So it juxtaposes.

And so what what f Scott Fitzgerald is saying here is that if you think you can hold that rabbit duck image at the same time, or if you really can do it, you're a genius. But to me, what happens is you can make things flicker, but you really can't hold opposing ideas in the mind. So there's a certain irony here because I'm your mind is breaking down the world and chopping it into pieces. And it's always doing so in contrast to what is not. And that's really interesting. I make a joke all the time.

I said, if you ask my grandmother in the 1970s, what are the chances of there someday being transgender bathrooms or gay people could marry or Marijuana would be legal or black man with precedent to set zero. You know, just like I would have said on September 10 2001. If someone said what are the chances of those two World Trade Center towers not being there at the end of your life, I would have said zero, then I would have been wrong. So it's interesting, the way you know when you think of transgender, but we really can't think of that because our mind is binary and thinks boy girl, but if you really think about it, and you think of transgender now your mind is going to juxtapose it with heterosexual. So it's really fascinating the way your mind always looks for the other. Right?

And I you know, that's why it's so beautiful that 100 years ago, Ken Scott, this journal thought of this
