So we’re interested in time travel when we think about philosophy of time. This guy claims to have time traveled to the future and visited his future self. He’s got video footage from his mobile phone that he hopes will prove it.
(For the record – I don’t think this is legit. If I had traveled back in time, I would have chosen to bring back more (and better) evidence than what this guy did claims to have done.)
Those two person-stages didn’t seem to be appropriately R-related; I doubt they are part of the same continuant person.
This is nothing… Time travel is possible but not in this way. Search about time travel paradox and multi universe’s and u will realise that u cant meet your self (literally) by travling in time.
Jots,
Of course it is nothing. I posted it as a joke. Like I said, I don’t think it’s legit. I thought it was funny (not serious).
However, many who do work in philosophy of time (and work on paradoxes of time travel) think it is not conceptually incoherent to meet yourself. See for example David Lewis’s “Paradoxes of Time Travel” in one of the footnotes he mentions a story called “All You Zombies” as an example of a conceptually coherent time travel scenario. It involves a person meeting oneself.
The reason it is conceptually coherent, according to philosophers like Lewis, to meet oneself is that it is conceptually coherent that one meet oneself in a previous time without making it be the case that some proposition of the (P and not-P) be true at the same time.
No way. It’s legit. Old guy had the same tattoo as young guy. Therefore, young guy = old guy.
