Above definitions from the Oxford Reference Online Premium.


bilking argument
n.
argument against backward causation posed by Max Black (1956) .
It goes as follows. If an event in the future causes an effect in the past it is possible to pre-empt the future cause between the events such that the effect occurs but not the cause. Thus, "assuming preemption is allowed, backwards causation cannot occur."
See an entry in the Stanford Encyclopedia of Philosophy. Still no word about the origin of the word bilking.


Weyl Curvature
n.
