If physical reality is nonseparable, as quantum mechanics suggests, th
en it may contain processes of a quite novel kind. Such nonseparable p
rocesses could connect spacelike separated events without violating re
lativity theory or any defensible locality condition. Appeal to nonsep
arable processes could ground theoretical explanations of such otherwi
se puzzling phenomena as the two-slit experiment, and EPR-type correla
tions. We find such phenomena puzzling because they threaten cherished
conceptions of how causes operate to produce their effects. But nonse
parable processes offer us an alternative deal of natural order, confo
rmity to which makes such phenomena seem quite normal and not at all u
nexpected. Attempts to answer the further question, as to whether an a
ppeal to a nonseparable process provides a genuine causal explanation,
have something to teach us about our concept of causation, but do not
threaten to undermine the value of the explanation itself.
