Thanks very much for this David, it is most intriguing. I am trying to wrap my head around this as I think it may be significant in my thinking on time. Not sure if you read my series on dual aspect monism, but one this is required of the psychophysical neutral foundation is that it cannot be limited by time and space, as time applies to mind not physical matter, and space applies to physical matter but not to mind. The neutral foundation therefore must be neither.

My question is about the comment I highlighted and copied. Are there no probabilities in the past? It seems the collapse happens in the present during observation so until that happens, is the physical reality of the past not undetermined? This is what John Archibald Wheeler and Eddington taught as you can see in my series or by reviewing the Atmanspacher and Rickles book on dual aspect monism. Wheeler created the delayed choice experiment to show that in the far distant past when a photon left a distant star it somehow exhibited the properties that were revealed when the collapse happened millions or billions of light years later. It's hard to fathom this idea of time and the role of the conscious observer, but it seems to be a well developed interpretation (among a great many others). Thoughts?
