That's like New Zealand is prettier than Australia. It is, but it's still freakin' New Zealand.

It's pretty cool. I think it does capture some of what's going on when we talk about possibility For instance, I want to be able to say that if Nixon ...

So to sum up to this point, 1. The ideas of necessity and possibility intuitively conjure possible worlds. 2. The obstacle to addressing modality in p...

What we can do is note this warning and proceed with the article. Is that ok with you?

You don't appear to be available for learning at the moment.

:up: Through European history those two sides revolve around one another since the ideological ancestors of the bourgeoisie were traveling merchants w...

That's fine.

The basic point of extensionality is substitutivity. Extension and intension are ways to define an expression. What were you thinking it was?

I like the idea of weight because weight is a result of gravity. Heavy (or massive) ideas bring other ideas into orbit around themselves. An example i...

When dolphins sleep, only half their brains rest. The other half keeps the opposing eye open, looking for predators and going up to the surface to bre...

I agree. True Marxism is about throwing the baby out with the bathwater, that is, everything we've done up to now has served its purpose and we're on ...

:up:

:up: I was poring over your example trying to get that right.

John asked if Frosty the Snowman is a Christmas themed character. The extension of "is a Christmas-themed character" is {Santa Claus, Mrs. Claus, Rein...

That's a good question. Strictly speaking, Marx was an apocalyptic prophet, not advising about how things should be, but predicting what will be. The ...

Was somebody trying to be compassionate toward vulnerable British women?

So we have multiple domains and interpretations. That gives us extension within worlds, but not across worlds.

Could you quote the passage you're referring to here?

:up: :up: :up:

So with Nixon winning the election, the domain is {Nixon} W(x) = won the election L(x) = lost the election W(Nixon) is true. But in the possible world...

I was talking about the stagflation crisis of the 1970s, which set the stage for the rise of Reaganomics, also called neoliberalism.

:up:

How is the domain set?

I can see that. :up:

Right, and that's the misalignment I was talking about in the OP. They're part of a political force that's trying to help people, but they actually de...

:up:

I wasn't arguing that conservative people are any less compassionate than their progressive brothers and sisters. My point was if you look at the rudd...

I think you mean working-class white men.

1.2 Extensionality Regained A quantifer tells us about the number of items in a domain that have a certain property, like all, or some. So "necessary"...

The kind of expression we're talking about is: Necessarily, all John's pets are mammals. There's no mention of possible worlds in this expression. So ...

Ok. I've got it.

Just a note on extension and intension. When I first learned about those ideas the word "definition" was attached. An extensional definition of "John'...

"Statement" and "proposition" are often used interchangeably. You just have to determine what the author means.

No, I don't think a proposition is something we necessarily agree on. It's a truthbearer. It's the content of a thought or belief, for instance if Joh...

1. Possible Worlds and Modal Logic In this first paragraph, the author of this article, Christopher Menzel, lays out the problem that possible world s...

Extending back to Socrates, there's an aspect of philosophy that is essentially a reflection on how we humans think. The highlights are points where w...

Thanks for starting us out. I think you're right that we could think of possible worlds as opposed to actual, but in this context, we're following Lei...

Hey, how badly can we mangle it?

I know. After saying that it's probably just going to be me commenting on the SEP. :grimace:

Definitely worth pondering, yes

Ok. What practical bullet points emerge from this?

Ok. It was Moliere who asked. I'm sure he will be interested in your perspective.

You can look up information on it if you think the Australian system could benefit from America's greater experience and wisdom. I work in an emergenc...

Maybe if you walkabout in the desert it will help. :grin: Look I'm quoting myself.

Cool.

Your wife is a compassionate person. Hint to her to watch out for scams. It's hard to avoid them these days.

You're such a compassionate person Banno. Thank you.
