[ExI] Deep roots of Quantum Mechanics

[Damien Broderick]

By the way, I recommend reading Hawking and Mlodinow's THE GRAND DESIGN 
for a baby-talk-level but still quite cogent discussion of the 
many-histories interpretation of QT. I think there's room in that 
interpretation for psi, especially including causally-retroactive psi, 
which would just be a term used for the selection effects or filters we 
daily apply to the many strands of alternative history contributing to 
the present moment.
