I discuss the mass parameters appearing in the gauge theory of the strong interactions, concentrating on the two flavor case. I show how the effect of the CP violating parameter θ is simply interpreted in terms of the state of the æther via an effective potential for meson fields. For degenerate flavors I show that a first order phase transition is expected at θ=π. I speculate on the implications of this structure for Wilson's lattice fermions.
