A new quantum paradox throws the foundations of observed reality into question (theconversation.com)

What I like about this article is that it is written in simple language that even I can almost understand.  Therein lies a paradox.  Can something involving a truly complex subject be expressed simply?  Okay, E equals M times C-squared seems simple enough, but if that is as far as one goes, he has not understood relativity.  Can anyone?  Or more precisely, can anyone ever adequately understand nature?  The deeper we dig, the more abstract our conclusions become.  Reality is not just abstract theory; it is what we experience.

The article mentions that some theories of reality do not require (or even exclude) free will.  But the absence of free will introduces insurmountable paradoxes, one of which was alluded to by JBS Haldane, when he pointed out that, if materialism is true, we could never know that, because our brains would be material.

Therefore, at the basis of any adequate theory of reality, there must be the fundamental property of free will (and therefore, consciousness, and therefore life).  Once we understand that we cannot understand, we will have a basis for making the most of what we do understand.
