Reading through Eric Wargo's Time Loops

I'm a little confused how that would even qualify as retro causation?
Would a tree that burned in a forest fire have some complicity  in the fire?

I think he's talking about the retrocausal "influence" in the aforementioned Dixon 2009 paper. So because the future influences the past - under a particular interpretation of the experiment - the dissolved state of the sugar is, in part, pulling the sugar cube into that dissolved state.

But it seems that for this to be an effective argument, IMO, there should be something missing in our understanding of dissolution...which again may be true but I've never heard of anything like that...

edit: Well I suppose one could say dissolution, like call causal processes, needs some explanation for causation itself but that IMO is different than something missing from the efficient. forward time description provided by chemistry on why sugar dissolves in water.
