  Assuming λ-independence (see section 2), any empirically adequate theory will have to violate OI or PI. A common view has it that violations of PI involve a different type of non-locality than violations of OI: Violations of PI involve some type of action-at-a-distance that is impossible to reconcile with relativity (Shimony 1984, Redhead 1987, p. 108), whereas violations of OI involve some type of holism, non-separability and/or passion-at-a-distance that may be possible to reconcile with relativity (Shimony 1984, Readhead 1987, pp. 107, 168-169, Howard 1989, Teller 1989).
