"In the Metaphysics of Quality 'causation' is a meta­physical term that can be 
replaced by 'value.' To say that 'A causes B' or to say that 'B values 
precondition A' is to say the same thing. The difference is one of words only. 
Instead of saying 'A magnet causes iron filings to move toward it,' you can say 
'Iron filings value movement toward a magnet.'"

This is helpful, pointing out that the result must be valued BEFORE it will
occur.  But still it is the POST-condition (= the effect = the iron filings moving
toward the magnet) that is valued, not the PRE-condition (= the iron  filings
lying inert).
So we have: 'A causes B' is to say 'B is the effect of A' is to say 'B is the valued
POST-condition which results from A (so it occurs)'.
