It is sometimes claimed that Lorentz covariant classical theories which allow superluminal propagation of signals are unviable because one can “violate causality” in such a theory by “building a time machine”. I will explain why such claims are unconvincing. I will then discuss a certain theory that can be formulated in either a superluminal or a subluminal form. It turns out that there is a sense in which the superluminal version is more predictive than the subluminal version. I will present theorems explaining why this is true more generally.
