Is it possible that the universe could be eternal??...

[GrandizerII]

The fact that it has no relevance to what I wrote is an important point.  Did you think that just Googling something that shared a few terms and posting it was smart?  It wasn't.

I think that the superposition principle from quantum mechanics casts doubt on the Aristotelian dialectic framework, or, to quote the philosopher John Locke,

Nah, it's a language matter, nothing more. The superpostion can be seen as comprising different instances of the "same" particle existing simultaneously at different positions, rather than the exact same particle existing at different positions at the same time.

Then again, I'm only addressing one of the two points make in Locke's quote, and possibly not understanding the point you're making here.
