What I'd like to know - is the beach still there or did it get washed away again in the last year?

Still there -- would be news again here in Ireland if that happened.

It's probably not the same sand, or at least not very much of it.

Lol is my vehicle a 97 Plymouth Grand Voyager or is it something newer? I call it a Theseus Grand Voyager.

Every seven years (or 10, depending on which story you hear) we become essentially new people, because in that time, every cell in your body has been replaced by a new cell. (Including the Brain)

Same person, or new person??

Why would you post a link to an article that disproves your own comment?

Both the 7 years portion and the brain cells being replaced?

I don't get it.

And tattoos. And teeth.

Give him a break, he only uses 10% of his brain, you know.

If I read Larry Niven's "Protector" in 2002, and re-read it again today in 2018, is it the same book, or a new book?

Is it the same person reading?

Or "Pierre Menard, Author of the Quixote" - https://en.wikipedia.org/wiki/Pierre_Menard,_Author_of_the_Q...

There are stories I reread after many years, where I had a rather different understanding the second time. I'm fine with saying that it's the same text but a different story, because the text is interpreted by the reader to become the story.

I'm also fine with saying it's the same story. The Mississippi is the Mississippi even though it isn't the same river.

Or in the UK the canonical example is still "Trigger's Broom"

I was wondering if someone had already posted this. Absolute classic.

This is great, how can I find more of these thought experiments?

@spacehome: “It's probably not the same sand, or at least not very much of it.”

What was wrong with that comment that it got voted into invisibility?

Interesting comment, but I suspect others disagree and they downvoted it.

Perhaps because it's rather obvious that it's different sand?
