Everyone is probably familiar with this classic, but it's a fun one:

From Oxford University's online philosophy course called "Philosophy Gym"

If there was a machine that destroyed all your atoms in Alpha Centurai, and reassembled an identical set here on Earth, would it be transporting you to Earth, or replacing you with a duplicate?

I gotta post this, mostly because I think it's super cool.  I've mentioned before that my other half was gonna be in a documentary, now it looks like it is coming together after a couple of years of development.  They even put up a segment of his interview.  When it comes out, spread the word.  Not because Don's in it, but because I believe everyone should see it.

If you wanna see who I'm so proud of, click "participants" ~ on that page, he's the last hexagon.   Notice all those other names?  He's in good company.  Click it and there's a bio w/ a clip of his interview.

There, I bragged.
