Changing the Subject: Redei on Causal Dependence and Screening Off in Relativistic Quantum Field Theory

In a recent pair of articles (Redei 1996, 1997), Miklos Redei has taken enormous strides toward characterizing the conditions under which relativistic quantum field theory is a safe setting for the deployment of causal talk. Here, we challenge the adequacy of the accounts of causal dependence and screening off on which rests the relevance of Redei’s theorems to the question of causal good behavior in the theory.
