We put forward the following, physically motivated premiss for constructing a theory
that underlies the standard model in four-dimensional space-time: The Euler-Lagrange
equations of such a theory formally resemble some equations of motion underlying
fluid-dynamics equations in the kinetic theory of gases. In support of this premiss, we
point out local and covariant Lagrangians whose Euler-Lagrange equations contain a
subsystem equivalent to the Euler-Lagrange equations of the standard model with
covariantly regularized propagators, and a subsystem describing faster-than-light effects.
