It cannot be proved that there are _not_ superluminal influences, but  
the results of the tests made e.g. by Salart et al. and Aspect et al.  
are interpreted by holding Bell inequality + extreme empiricism EE as  
premisses, and this gives the interpretation that the tests show that  
there are superluminal influences.    (02)

EE: particles do not have properties which exist prior to the measurement.    (03)

Bell inequality: The results of the "nonlocality tests" (which ought  
to be called the correlation tests) violate one or both of the  
following premisses:
1) particles have properties which exist prior to the measurement, and  
which determine the outcome of the measurement; 2) there are no  
superluminal influences between the particles.    (04)

If the Universe would be nonlocal, then 2) would be violated, but the  
conclusion that the Universe is nonlocal requires EE as a premiss, and  
EE is in contradiction with 1. When EE is explicitly written out, it  
is seen that EE is implicit in the interpretation that the nonlocality  
tests show that there are superluminal influences.    (05)

In short, EE denies ontological realism (particles have properties  
which exist prior to the measurement) which has the effect of bringing  
in a great deal more metaphysics than EE was supposed to shave away. I  
mean the marriage of e.g. three-valued logic, extreme formalism, and  
the transcendental many-worlds interpretation in the interpretation of  
quantun theory.    (06)
