I heard an interesting philosophical question and wanted to hear other people's thoughts on it.

If I drive my car down a really long road and while I drive parts of my car wear out and have to be replaced. My tyres burst, the chassis rusts and so on until after I have driven a million miles every part of my car has been replaced. The question is, is it still the same car?

I personally think that the car changes every time it is driven with the engine wearing out a little more, the tyres becoming a little more worn and so on so it is a different car but i wanted to hear your opinions.

I heard of this.
I think that its somehow something in the middle, not the same car, but not a different (or it is the same car, yet it is also a different one).

This looks like a known paradox with a human and his cells be replaced internally, molecule-wise. I'd say it's the same car but slowly changing in parts. Even if you have replaced the total set of parts (or even more than once) one at a time, it's still the same car. But if you replace all of them at once, you've reforged a new car instead since you don't have a basis to call a "car in repair" while you perform such a replacement. The same actually is true IMHO with a human.

"Same car, but not the same as it was at the beginning of the road" is what comes to my mind.

Defining one thing from another is just something animals do.
Legally and personally it would be the same car but universally "the car" represents a bunch of matter which happens to remain relatively close together for a time, being added to/removed from all the time.
Like a lake which a river runs into and out of.

Well the way I looked at it is, if you have a car and something happens to it the car has changed. If something has changed it is no longer the same, therefore it's a different car. We consider it the same because it effectively is the same but it's not actually the same.

I don't think it's too philosophical. I mean, you'd first have to define 'same' as an axiom or constant for this to have any debatable meaning. If by same you mean exactly what you had when you started, then clearly not. Even if nothing bad happened, the car now weighs more as it has dust on it, therefore it is not the same car. So until we know what you mean by 'the same car' it's a little impossible for me to think about this philosophically. I mean, what represents the integrity of the old car? The materials used to build it? what if the new tire was exactly the same in name, brand, molecule size, and atom distribution. Would that still be 'the same tire'!?
Kinda scary
Idk I'm not good at this

As long as one original piece remains, and as long as every piece replaced is the same as the original, i still would view it as the same car.

the human analogy doesn't really work because nerve cells don't die

If nerve cells didn't die we could essentially live forever. They do die around 100 years after forming.*
*Not an exact number.

I think what he meant about nerve cells not dying is - is that we usually die before they do.

its not the SAME car but it is. it just repaired with identical parts, its like breaking your arm and getting a cast with your bones repairing themselves. sure there's new bone marrow there but its still your arm

Reminds me of one of my old thought experiments. Except the car was an old ship.

I wonder if this is more about the changes one goes through in life and how a person changes because of their choices in life and how those decisions affect them.

Yeah. I'd imagine if someone were to by driving this car, or if the car were driving itself rather, then the car wouldn't drive completely straight for it's 1 million mile journey.

By that do you mean the obstacles one faces in life and the paths one chooses?
